    DEVICE AND METHOD FOR PRESSURE CONDITIONING OF A
    CONTAINER FOR TREATMENT AND PACKAGING MACHINE
    ASSOCIATED PRESSURE
    The present invention relates to the field of bottling, and relates in particular to a device and a method for conditioning under pressure of a container to be treated at least partially filled with a content and sealed in a sealed manner by a stopper disposed above of a head space of the container, and on an associated pressure conditioning machine.
    Subsequently, by content is meant a liquid or semi-liquid food product intended to be marketed outside the cold chain such as an acid fruit juice, in a container, a container within the meaning of the present invention being an envelope made of polymeric material such as a bottle, provided with a cap of known type, intended to hermetically seal the bottle after filling, generally with a screw.
    The liquid or semi-liquid food contents are sensitive to microbial development and the organoleptic qualities are very quickly modified in the absence of a sterilization treatment for pathogenic organisms and / or the presence of oxygen.
    In known manner, the high temperature heat treatment of the order of 90 ° C. for a few seconds, also called flash pasteurization, is also applied to edible liquids or semi-liquids having a pH of less than 4.7, such as juices by example. In this known process, the liquid is treated in a specific unit, prior to filling which must be carried out in a sterile manner. Care must therefore be taken to keep the chain sterile.
    This known filling method consists of cold filling in a sterile environment, the container and its cap being sterilized cold using a sterilization liquid and then rinsing and the content is then introduced into this container in an aseptic atmosphere. The advantage is to use packaging which requires little material because the necessary mechanical properties are limited. The process does not generate volume variations related to temperature variations. In addition, the necessary mechanical properties being limited, the external aesthetic forms are freer. However, the oxygen contained in the headspace can be consumed and there is then a depression in the bottle. It is therefore necessary to provide either a bottle resistant to this depression, or a compensation for this depression.
    This sterile technique results in complex, costly installations and rigorous maintenance, which itself is costly. In addition, quality control can only be carried out by sampling, there is therefore no systematic control and therefore no certainty as to the sterilization of the liquid or semi-liquid food content thus conditioned.
    Another known solution is that of sterilization simultaneously with filling by introducing a sterilizing liquid. It is understood that the addition of a sterilizing product, which is a chemical compound, is not necessarily accepted by all the health laws of the countries and that the consumer himself may be reluctant to absorb not only the liquid food product or semi-liquid he chose but also the residual sterilizing product introduced. Such preservatives can induce changes in organoleptic qualities both during storage and after opening the packaging.
    A last solution among the main solutions known from the prior art, consists of filling a package with heat, that is to say of introducing the content brought to a high temperature directly into the container without it having undergone a sterilization treatment. In this case, it is the content itself which ensures the sterilization of the container because it is introduced at a temperature allowing the destruction of pathogenic organisms, therefore greater than 73 ° C., generally 85 ° C. The packaging is closed and immediately agitated, generally by inversion, in order to heat treat all the internal surfaces of the container, including the internal face of the stopper.
    The stopper in the case of hot stoppering is a stopper of known type, single material, obtained by molding, checked before installation to avoid any fitting of a defective stopper. Such caps are extremely inexpensive.
    This solution is interesting because it guarantees that each package is necessarily sterilized internally, without there being any shortage.
    If the stopper is inexpensive, the drawback of hot filling is that it requires packaging which is resistant on the one hand to the temperature and on the other hand to the phenomenon of collapsing linked to the shrinking of the volume of the liquid during cooling, this which depresses the interior of said container. In addition, the oxygen in the air trapped during filling is also consumed after cooling by the liquid or semi-liquid food composition, which causes a delayed depression which
    can also cause a 4deformation additional of container. The packaging must so be mechanically resistant and / or deformable, need a quantity of
    important material and often a specific architecture with panels to resist deformations of this packaging and / or to compensate for depression by appropriate deformations. Thus funds can take two positions, one of which is inwardly deformed under the effect of the depression so as to compensate for the said depression. The deformation of the bottom being under the bottle, this does not cause any problem of stability of the bottle when it is placed on said bottom, only the digging of the bottom is more pronounced, which is invisible, except when looking from below. It is understood that such a background must be sophisticated, complex to produce and involves an obvious additional cost.
    It should be noted that this also goes in the opposite direction of the needs for sustainable development which aim at a reduction in the quantities of polymer material used, which also has an impact on the price of manufacture and an impact on recycling therefore on the final price.
    However, this process is the one that requires the simplest packaging lines both for installation and maintenance, which is simple to control since the main control relates to a single parameter: the temperature of the content.
    Other compensation solutions have been implemented, one of them for example consists in introducing a drop of liquid nitrogen into the headspace immediately before capping. Liquid nitrogen passes to the gaseous state with a very large increase in volume, which places the volume of the bottle under pressure and makes it possible to compensate, as and when cooling, the volume of retraction of the liquid. In the final state, at room temperature, equilibrium is found and nitrogen can only cause additional inerting. However, this process is relatively complex to master and fairly difficult to reproduce.
    Advances in the processes and materials of the containers have improved performance. Nevertheless, the aim which is also that of the present invention, is to be able to carry out in particular the hot filling using bottles having an overweight of material as low as possible compared to the containers used for filling in a sterile environment, cold.
    It is also useful to be able to compensate for depression in cold-filled containers which can also undergo deformation by depression, or even to improve their mechanical strength, especially if the containers themselves have low mechanical resistance, which is also a objective of the present invention.
    It is therefore necessary to propose a method for compensating for the depression in a container, at a minimum, and more generally for controlling the overpressure, in particular in the case of hot filling. This overpressure, after cooling, makes it possible to compensate for the reduction in volume of the head space which is a few percent on cooling. This overpressure also makes it possible to compensate in the long term for the reduction in pressure linked to the consumption of oxygen.
    These different sources of pressure reduction, when no compensation or even overpressure is provided, cause the bottle to deform and make it unfit for sale. These depressions also lead to poor grip by consumers but also to poor mechanical strength of the containers during transport by pallets, even filmed.
    Patents are known which have proposed a compensation process, such as patent applications FR 2322062 A1 and US 2015/0121807 A1 which propose to inject a gaseous fluid into the headspace through a specific closure member. Such a device consists in introducing a needle through the closure member, injecting a gas through the needle into the head space and removing said needle, the closure member itself ensuring the seal. It turns out that you need a sealing device with specific means, which is totally unacceptable in terms of the price of packaging. In addition to the price and in addition, this generates complex problems related to the presence of several materials, the complexity of quality control, the difficulties in recycling and the uncertainty of the quality of the capping. In this case, a membrane is provided which can only act as a barrier to the liquid during hot filling, for example because the liquid will not pass behind the membrane, then the sealing member is perforated, which introduces possible organisms. included behind the membrane which will migrate into the container.
    Another device also uses an even more specific plug, that described in patent application WO 2009142510 A1. This plug comes from manufacturing with an opening. After filling, the head space is placed in a pressurized enclosure, a plugging plug is introduced into the hole provided for this purpose, said plug being immobilized in the hole by mechanical means. Such a process is totally unthinkable industrially, both from the point of view of rates and price, as well as difficulties of control and even implementation.
    In addition, the devices known in the prior art do not make it possible to precisely check the quality of sealing the hole formed in the stopper in order to guarantee perfect sealing of the container.
    The present invention aims to solve the drawbacks of the prior art, by proposing a device and a method for conditioning under pressure of a container to be treated at least partially filled with a content and sealed in a sealed manner by a stopper disposed above a head space of the container, said device comprising a cover with a needle and a heating cannula arranged therein so that their respective axes of movement intersect at a point located in the material of the stopper or above the material of the stopper when the cover is docked on the stopper, the end of the heating cannula being convex, preferably hemispherical, which makes it possible to be able to carry out in particular a hot filling using bottles having a the lowest possible material overweight compared to the containers used for filling in a sterile cold environment, and this allows and also to compensate for the depression in cold filled containers which can undergo deformation by depression, especially if the containers themselves have low mechanical strength. In addition, the convex shape of the end of the heating cannula makes it possible to carry out a precise verification of the quality of closure by the heating cannula of the hole formed in the plug by the needle.
    The subject of the present invention is therefore a device for conditioning the pressure of a container to be treated at least partially filled with a content and sealed in a sealed manner by a stopper disposed above a head space of the container, said device comprising a cover which comprises inside of it a piercing needle, means for injecting fluid and a heating cannula for obturation by fusion, said cover being configured to be docked sealingly on the external surface of the stopper , said needle being able to move linearly to pierce a hole through the plug, said fluid injection means being configured to introduce a fluid into the head space via said hole, said heating cannula being able to move linearly to close said hole by melting the material of the plug, characterized in that the needle and the heating cannula are disposed in the cover so that their respective axes of movement intersect at a point located in the material of the stopper or above the material of the stopper when the cover is approached on the stopper, and by the fact that the end of the heating cannula is convex.
    The end of the heating cannula is preferably hemispherical.
    Thus, said pressure conditioning device for a container to be treated makes it possible in particular to carry out hot filling by using bottles having an overweight of material as low as possible compared to the containers used for filling in a cold sterile environment, and also makes it possible to compensate for the depression in cold filled containers which can undergo deformation by depression, especially if the containers themselves have low mechanical resistance.
    The needle and the heating cannula are inclined with respect to each other so that their respective longitudinal axes of movement intersect at the same point in the material of the plug or above the material of the plug. Preferably, said point is located at the center of the upper surface of the stopper.
    A person skilled in the art can easily proceed by tests and measurements to ensure that in the closed position of the heating cannula on the stopper, the top of the convex shape of the cannula coincides with the hole formed by the needle: the axes of movement are thus intersecting on the material of the plug or above it, depending on the convex shape adopted by the end of the heating cannula.
    The needle is movable, in the position of docking of the cover on the plug, between a retracted position and a drilling position to pierce the plug. The heating cannula is movable, in the position of covering of the cover on the stopper, between a rest position and a closing position to close by fusion the hole formed in the stopper by the needle, the plastic material of the stopper melting in contact with the heating cannula.
    The needle is never in contact with the contents during drilling.
    The stopper used in the context of the invention and therefore in this process is a conventional one-piece stopper, without an internal membrane and therefore inexpensive and easy to recycle. The invention is not, however, limited in this regard. By way of nonlimiting example, the following plugs also come within the scope of the present invention, and can be used with the process of the invention:
    - a stopper comprising an annular membrane (or inner covering or liner) hollowed out in its central part, - a stopper comprising a full membrane (or inner covering or full liner) but with a central thickness less than the minimum thickness necessary for a car -tightness in the case of drilling and subsequent withdrawal of a needle from the stopper, this minimum necessary thickness being below 0.2 mm, - a stopper comprising a full membrane (or inner coating or full liner) 0.2 mm to 0.8 mm thick, with a polyethylene / ethylene vinyl acetate (PE / EVA) material which does not have a proven self-sealing characteristic after removal of a needle drilling diameters between 0.1 mm and 3 mm.
    This device is preferably used for hot content filling, but can also be used for cold content filling.
    The heating cannula allows the hole formed in the stopper by the needle to be filled, by melting the plastic of the stopper, which guarantees the final tightness of the container while compensating for the depression in the container.
    The container thus contains a content with a balanced pressure to say the least and preferably under a slight pressure so that the pressure difference π
    internal with the external pressure of the container avoids generating any collapsing of the container.
    In addition, the convex, preferably hemispherical, shape of the end of the heating cannula makes it possible to carry out a verification with precision of the quality of closure by the heating cannula of a hole formed in the plug by the needle. Indeed, the shape of the obturation formed by the convex heating cannula depends on the shape of the end of the heating cannula, the temperature of the end of the heating cannula, the contact time of the heating cannula with the plug and the depth of penetration of the heating cannula into the plug. Once the convex shape of the end of the heating cannula is known, the temperature of the end of the heating cannula determined as a function of the material constituting the stopper, the contact time determined as a function of the desired treatment time, the those skilled in the art will be able to adapt the depth of penetration into the plug by tests and measurements. A characteristic mark of a certain diameter will be formed on the upper surface of the stopper, which, the shape, the temperature of the end of the cannula and the contact time being known, will ensure that the heating cannula has had sufficient penetration to guarantee a tight seal. It is understood that the person skilled in the art can, only the convex shape of the end of the heating cannula being imposed, fix two parameters among the temperature of the end of the heating cannula, the contact time and the depth of penetration to adapt the third parameter in order to determine the mark of the heating cannula on the upper surface of the stopper which guarantees optimal sealing.
    According to a particular characteristic of the invention, the device further comprises an optical means configured to check the quality of closure of the hole in the plug by the heating cannula. The optical means can be a camera or an optical fiber connected to an optical sensor. The optical means can be arranged in the cover or on a downstream station on a production line having the device of the invention.
    Thus, it can be checked optically, using the optical camera, whether the quality of filling the hole with the heating cannula is good or bad, in order to carry out the fusion filling step again or to throw away the stopper / container in the event that poor sealing quality is detected.
    According to a particular characteristic of the invention, the device further comprises an optical or inductive means arranged in the cover and configured for
    check Integrity of the needle after the piercing of hole. So we can optically check, using of this way optical or inductive, if the needle is where no
    broken after the piercing step, to replace the needle and discard the contents of the container in the event that a break in the needle is detected.
    A remote optical camera can monitor the filling level of the container at the end of the pressure conditioning process to detect any breakage of the needle. In fact, during normal processing, the content level must drop to a predetermined level, while in the event of non-drilling and therefore of no introduction of fluid, the content level will not drop.
    A proximity sensor system could also monitor the presence of the full, unbroken needle. Such proximity sensor systems could for example be a photoelectric or magnetic cell.
    According to a particular characteristic of the invention, the needle has a pointed end in the shape of a cone.
    Thus, said needle is more solid compared to a hypodermic needle with beveled end used in the prior art, which makes it possible to prevent said needle from breaking during the piercing step.
    Said needle provides a hole by penetration into the plastic of the plug, by deformation and pushing back of the material, without tearing of material. No plastic waste from the plug thus falls into the contents of the container.
    The diameter of the drilling hole must allow a rapid inflation (the largest possible diameter) and a welding safety (the smallest possible diameter) to be combined. By way of nonlimiting example, a needle with a diameter of 0.7 mm seems to constitute a good compromise. It is understood that the invention is not limited in this regard, the diameter of the needle can be between 0.3 and 0.8 times the thickness of the plug. The thickness of the plug is defined as the maximum thickness of the flat surface of the plug from which extends the skirt of the plug carrying the thread.
    According to a first embodiment of the invention, the needle is full, the fluid injection means comprising at least one fluid inlet capable of receiving a fluid under pressure and of injecting it inside the cover docked tightly on the cap.
    Thus, during the injection of fluid, the solid needle is withdrawn from the hole formed in the stopper in order to allow the introduction of the fluid into the head space of the container via said hole. In this first embodiment, sterilization of the outer surface of the stopper before the cover comes into contact with the stopper is compulsory so as not to pollute the content during the introduction of the fluid into the head space.
    The withdrawal of the needle during the injection of fluid also makes it possible to avoid splashing the needle when connecting said needle to any content on the introduction of fluid which creates a turbulence of the surface of the content, for improved hygiene.
    According to a second embodiment of the invention, the pointed end of the needle is full, and the rest of the needle comprises a longitudinal central bore and at least two opposite lateral holes central bore with the outside close to the pointed end of the needle, the fluid injection means comprising at least one fluid inlet capable of receiving a fluid under pressure and of injecting it into the central bore of the needle at the level of the end of the needle opposite the pointed end of the needle.
    Thus, the needle is full at its tip but pierced in its center with two lateral openings, which makes it possible to introduce fluid into the head space of the container while the needle is still in its piercing position, the fluid being diffused laterally in the headspace through the two lateral holes of the needle, thus making it possible to avoid any turbulence of the content and splashes during the introduction of fluid. This second embodiment makes it possible to avoid prior sterilization of the external surface of the stopper, which is an important point from an industrial point of view.
    According to a particular characteristic of the invention, the needle is heated by a heating means.
    Thus, heating the needle makes it possible both to sterilize the needle and to facilitate the piercing of the plastic material of the stopper. The needle is preferably heated to a temperature above 95 ° C for sterilization and below 130 ° C to avoid possible melting of the plastic of the plug during drilling and sticking of plastic particles on the needle which could then come off when piercing the cap of another container in a next cycle.
    The temperature of the needle is preferably maintained and continuously monitored by a resistor / probe placed in the holder of the needle.
    The present invention also relates to a process for conditioning under pressure of a container to be treated at least partially filled with a content and sealed in a sealed manner by a stopper disposed above a head space of the container, at the using a pressure conditioning device as described above, characterized in that it comprises the following steps: docking in a sealed manner of the cover of said device on the external surface of the plug; drilling a hole through the plug using the needle of said device; the introduction of a fluid into the head space of the container via said hole, formed through the plug, using the fluid injection means of said device, so as to obtain a residual pressure at the less equal to atmospheric pressure in the headspace of the container; closing said hole by melting the material of the plug using the heating cannula; and removing the cover.
    Thus, said pressure conditioning process of a container to be treated makes it possible in particular to carry out a hot filling using bottles having an overweight of material as low as possible compared to the containers used for filling in a cold sterile environment, and also makes it possible to compensate for the depression in cold filled containers which can undergo deformation by depression, especially if the containers themselves have low mechanical resistance.
    The temperature of the heating cannula and the contact time can be set individually to obtain the desired penetration / welding and are continuously monitored by the pressure conditioning device.
    The temperature at the end of the heating cannula is of the order of 140 ° C - 220 ° C to ensure the rapid melting of the plastic of the plug.
    A minimum force, for example using a cylinder controlled at 7 bars, is applied to the heating cannula to ensure significant compression of the plastic during the melting phase to fill the hole. Insufficient pressure from the heating cannula despite the right temperature and good contact time compromises the quality / tightness of the weld. Experimentally, the Applicant has found good weld imprints for a contact time of 0.4-0.5 seconds, at 7 bars, with a temperature of 180 ° C. at the end of the cannula, for high density polyethylene plugs ( HDPE).
    The cannula is heated by a resistance / temperature probe connected to the device.
    A water cooling circuit placed in the hood preferably ensures that the hood is kept at a "reasonable" temperature.
    According to the first embodiment of the pressure conditioning device of the invention, the needle is withdrawn from the hole before the step of introducing fluid.
    Thus, the docking of the cover on the cap being carried out in a sealed manner, the needle can be raised, before the step of injecting fluid, while maintaining the pressure between the cover and the cap, the drilling is therefore clean without shavings or waste by pushing back the plastic material from the stopper only, the withdrawal of the needle during the injection of fluid also making it possible to avoid possible splashing of the contents on the needle during the introduction of fluid which creates turbulence on the surface of the contents, for improved hygiene.
    According to the second embodiment of the pressure conditioning device of the invention, the needle is held in the hole during the step of introducing fluid, the introduction of fluid taking place through the central bore and the at least two side holes of the needle.
    Thus, the fluid is diffused laterally in the headspace through the two lateral holes of the needle, thus making it possible to avoid any turbulence of the content and splashes during the introduction of fluid, and also allowing '' avoid prior sterilization of the outer surface of the cap.
    According to a particular characteristic of the invention, the method further comprises, after the sealing step, a step of verifying the quality of sealing the hole in the plug using optical means.
    Leak test systems are currently available to test the quality of the weld. However, for a hole of about one micron (which allows the return of the atmospheric pressure of the container in a week), the control time is approximately thirty seconds, so there would have to be a number of control covers fifteen times greater than the number of treatment covers, which is prohibitive.
    The optical means therefore makes it possible to verify the quality of the shutter immediately after the shutter step when the cover is still docked on the plug, or at a post downstream on a production line in which the device is placed according to 1 'invention.
    According to a particular characteristic of the invention, the verification step comprises the following sub-steps: the capture, by optical means, of an image of the plug at the level of the circular obturation formed by the convex heating cannula; measuring the diameter of the captured circular obturation; and comparing the measured diameter to a threshold value to determine whether the shutter quality is acceptable or not.
    Thus, the optical means allows a visual control of the obturation by fusion to measure the penetration of the cannula and guarantee the quality of the weld.
    According to a particular characteristic of the invention, the step of introducing fluid into the head space comprises introducing fluid in an initial phase at a first pressure value, then introducing fluid in a final phase at a second pressure value lower than the first pressure value for acceleration of the process according to the invention.
    Thus, it is possible to greatly increase the pressure in the initial phase of pressurization immediately after drilling, and to have a lower pressure in the final phase in order to adjust the final pressure just before obturation by fusion.
    According to a particular characteristic of the invention, in the case of hot filling at a temperature above 73 ° C, the fluid is introduced into the head space after the contents have cooled to a temperature below 45 ° C .
    According to a particular characteristic of the invention, the fluid introduction pressure is configured to generate a residual pressure in the container, between 1.01 bars and 2.5 bars, and preferably between 1.01 bars and 1, 4 bars.
    According to a particular characteristic of the invention, the fluid is an inert and sterile gas such as nitrogen, in particular in gaseous form.
    Thus, the inert and sterile gas makes it possible not to cause subsequent oxidation of the content, after bottling. This avoids overcollapsing due to the subsequent consumption of oxygen since there is none or very little, the inert gas having largely replaced the initially confined air.
    According to a particular characteristic of the invention, the method further comprises, before, during and / or after the step of docking the cover on the stopper, a step of circulating sterile fluid between the cover and the stopper, preferably an inert gas, more preferably nitrogen.
    Thus, this circulation of sterile fluid makes it possible to prevent bacteria from entering the space between the cover and the stopper from the outside, in order to ensure the sterility of the container. An overpressure is created between the cap and the cover to maintain a positive pressure greater than or equal to the internal pressure of the container until the obturation by fusion.
    According to a particular characteristic of the invention, the method further comprises, before the step of docking the cover on the stopper, a step of sterilizing the external surface of the stopper by one or more from one-off heating, chemical sterilization , steam, pulsed light emission, or the like.
    Thus, punctual heating or chemical sterilization using a sterilizing liquid ensures the destruction of pathogenic organisms present on the outer surface of the stopper.
    The present invention further relates to a pressure conditioning machine comprising at least one pressure conditioning device as described in pressure
    above, said machine conditioning including in besides a means of maintenance in containing by report to which the 1 'hood device of conditioning in pressure es
    between a rest position distant from the means for holding in the container position and a docking position in which the cover is sealingly approached on the cap of the container to be treated.
    To better illustrate the object of the present invention, two preferred embodiments will be described below, by way of illustration and without limitation, with reference to the accompanying drawings.
    In these drawings:
    - Figure 1 is a perspective view of a pressure conditioning device of a container to be treated according to the present invention;
    - Figure 2 is a sectional view of the device of Figure 1 in the non-docked position;
    - Figure 3 is a sectional view similar to Figure 2 during the docking step;
    - Figure 4 is a sectional view similar to Figure 21or the drilling step;
    - Figure 5 is a sectional view similar to Figure 2 during the fluid introduction step according to a first embodiment of the invention;
    - Figure 6 is a sectional view similar to Figure 2 during the sealing step;
    - Figure 7 is a sectional view of the heating cannula of the device of Figure 1;
    - Figure 8 is a perspective view of the end of the heating cannula of Figure 7;
    - Figure 9 is a sectional view of the needle of the device of Figure 1 according to a second embodiment of the invention.
    If we refer to Figure 1, we can see that there is shown a pressure conditioning device 1 of a container to be treated 2.
    The container to be treated 2 is at least partially filled with a content and sealed in a sealed manner by a plug 3 disposed above a head space of the container 2.
    In the case of the current description, the containing 2 undergoes a hot filling, and is a bottle, especially in FART (polyethylene terephthalate) , of
    low grammage, with a content, such as a fruit juice, brought to a temperature capable of destroying pathogenic organisms, namely a temperature above 73 ° C, in this case 85 ° C.
    Once the container 2 is filled with the hot content, it is closed by the plug 3 of known type, namely a screw cap injection or compression molded, monolithic and single-material free of any additional sealing element.
    The seal is obtained by contact under mechanical pressure of the material of the plug 3, in this case its inner face on the material of the peripheral edge of the neck 2a of the container 2, the screwing making it possible to exert said necessary mechanical pressure.
    During the closing, said plug 3 leash subsist an area of head. This space results from filling without overflow because the content does must in In no case overflow and meet on the lip of neck 2a before closing because the contents would then a door input under the plug 3 and the containing 2 would be improper on sale
    The plug 3 is free of any mechanism or any other pressure compensation accessory. The air trapped in the headspace is hot but at atmospheric pressure.
    It should be noted that the present invention also applies to certain plugs commonly used, in particular in the United States, which are of the bi-material type with an internal membrane used to ensure only the seal between the surface of the neck of the container 2 and the plug 3 by compression during screwing, unlike the inner lip for single-type plugs. However, this inner membrane for such a bi-material stopper does not have the characteristics necessary to ensure self-sealing of the stopper in the case of drilling with a needle and then withdrawal of the needle from the plug.
    The container 2 is capable of receiving a content at the sterilization temperature adopted without degradation but is free from means of compensation for depression.
    The container 2 is set in motion immediately after filling with the content, in order to bring all the internal surfaces of the container 2 into contact with the content brought to sterilizing temperature.
    The container 2 and its contents are then cooled in a cooling tunnel by spraying water, for example to bring the assembly close to ambient temperature.
    When the containing 2 reaches a temperature below 75 ° C , of makes material which constitutes it, said container 2 is collapse because volume gas and liquid gets reduced up to 3 to 5 O.where inside the container 2. This reduction increases at as and as
    cooling. The collapsing phenomenon is close to its maximum at a temperature less than or equal to 45 ° C.
    The pressure conditioning device 1 comprises a cover 4, also called docking head, which comprises inside of it piercing means 5, fluid injection means 6 and means for closing by merger 7.
    The pressure conditioning device 1 further comprises a horizontal lower support 8 on which the container 2 is positioned, a horizontal upper support 9 comprising a notch 9a into which the neck 2a of the container 2 is inserted, and a vertical support 10 to which are connected the lower support 8 and the upper support 9.
    The cover 4 is vertically movable, by means of a vertical displacement motor 11, between a rest position distant from the upper support 9 and a docking position in which the cover 4 is docked in a sealed manner on the plug 3 of the container to be treated 2. It is understood that the invention is not limited in this respect: either the cover is movable, docked on the container brought under the cover, or the cover is fixed, the container being brought into the hood.
    The pressure conditioning device 1 is configured to implement a pressure conditioning process for the container to be treated 2 which comprises the following steps: sealingly approaching the cover 4 on the external surface of the plug 3; drilling a hole through the plug 3 by lowering the drilling means 5 towards the plug 3; the introduction of a fluid into the headspace of the container 2 via said hole, formed through the plug 3, using the fluid injection means 6, so as to obtain a residual pressure at least equal to atmospheric pressure in the headspace of the container 2; closing said hole in the plug 3 by melting the material of the plug 3 by lowering the plugging means by fusion 7 towards the plug 3; and removing the cover 4. The different stages of the process will be described in more detail in FIGS. 2 to 6.
    The docking of the cover 4 on the plug 3 being carried out in a sealed manner, in the first embodiment of the invention, the piercing means 5 can be reassembled, before the fluid injection step, while maintaining the pressure between the cover 4 and the plug 3, the drilling is therefore clean without chips or waste by pushing back the plastic material of the plug 3 only, the withdrawal of the drilling means 5 during the injection of fluid also making it possible to avoid possible splashing of the content on the piercing means 5 for improved hygiene.
    The stopper 3 used in this process is a conventional one-piece stopper, without an internal membrane and therefore inexpensive.
    The container 2 thus contains a content with at least a balanced pressure and preferably under a slight pressure so that the difference in internal pressure with the external pressure of the container 2 avoids generating any collapsing of the container 2.
    If we refer to Figure 2, we can see that there is shown the pressure conditioning device 1 in the non-docked position of the cover 4.
    The container 2 is partially filled with a content 12 so that a headspace 13 without content remains at the neck 2a of the container 2, the container 2 being tightly sealed by the plug 3 disposed above the head space 13 of container 2.
    The piercing means 5 comprise a piston 14 at the end of which a needle 15 is fixed, said piston 14 being able to move linearly in a cylinder 16 formed on the cover 4, the stroke of the piston 14 being limited by a piston 17 formed in the upper end of cylinder 16.
    Thus, the needle 15 is configured to pierce the plug 3 when the cover 4 is approached on the plug 3 and the piston 14 is in its deployed position.
    The sealing means 7 include a piston 18 at the end of which is fixed a heating cannula 19, said piston 18 being able to move linearly in a cylinder 20 formed on the cover 4, the stroke of the piston 18 being limited by a piston chamber 21 formed in the upper end of the cylinder 20.
    Thus, the heating cannula 19 is configured to close by fusion the hole formed in the plug 3 by the needle 15 when the cover 4 is approached on the plug 3 and that the piston 18 is in its deployed position, the plastic material of the plug 3 melting in contact with the heating cannula 19.
    The needle 15 and the heating cannula 19 are located in an internal cavity 22 of the cover 4.
    The pistons 14 and 18 can be actuated electrically or hydraulically. In order not to overload the figures, the electrical power or hydraulic actuation wires of the pistons 14 and 18 have not been shown in the figures. Likewise, the heating elements making it possible to heat the needle 15 or the heating cannula 19, as well as their respective electrical supplies, have not been shown so as not to overload the figures.
    The fluid injection means 6 comprise several fluid inlets capable of receiving a pressurized fluid and of injecting it inside the internal cavity 22 of the cover 4, the cover 4 being able to contain up to five inlets of fluid 6.
    In the first embodiment of the invention, the pressure conditioning process also comprises, before the step of docking the cover 4 on the plug 3, a step of sterilizing the external surface of the plug 3 by punctual heating, by chemical sterilization using a sterilizing liquid, by steam, by emission of pulsed light or by another similar process, in order to ensure the destruction of the pathogenic organisms present on the external surface of the stopper 3.
    The internal cavity 22 of the cover 4 is always under overpressure of sterile gas by a first fluid inlet 6, even before docking to maintain the sterility of the plug 3 produced beforehand.
    There are two other sterile gas inlets 6 for the fluid introduction step, also called the inflation step.
    The last two fluid inlets 6 could be used for injecting a sterilizing fluid after docking and drilling and rapid evacuation by suction of the sterilizing fluid before drilling.
    The device 1 further comprises an optical camera C disposed in the internal cavity 22 of the cover 4 and configured to check the quality of sealing the hole in the plug 3 by the heating cannula 19. This step of checking the quality of the sealing will be described in more detail with reference to Figure 6.
    If we refer to Figure 3, we can see that there is shown the pressure conditioning device 1 during the docking step.
    During the docking step, the pistons 14 and 18 respectively of the needle 15 and the heating cannula 19 are in their retracted positions, also called rest positions.
    The cover 4 is docked in a sealed manner on the external surface of the plug 3 so that at least part of the plug 3 is inserted into at least part of the internal cavity 22 of the cover 4.
    The pistons 14 and 18 are arranged in the cover 4 so that their respective axes of movement intersect at a point located in the material of the plug or slightly above it when the cover 4 is approached on the plug 3, said point preferably lying at the center of the upper surface of the plug 3 or slightly above, eccentric, depending on the shape of the heating cannula 19.
    The pressure conditioning process may also include, after the step of docking the cover 4 on the plug 3, a step of circulating sterile fluid, preferably an inert gas such as nitrogen, in the internal cavity 22 of the cover 4 via some of the fluid inlets 6. An overpressure is thus created between the plug 3 and the cover to maintain a positive pressure greater than or equal to the internal pressure of the container 2 until the obturation by fusion.
    If we refer to Figure 4, we can see that there is shown the pressure conditioning device 1 during the drilling step.
    During the drilling step, the piston 14 of the needle 15 is in its deployed position, so that the needle 15 is lowered to the plug 3 and drills a hole 23 through the material of the plug 3.
    The needle 15 is never in contact with the content 12 during drilling.
    The needle 15 makes the hole 23 by penetration into the plastic of the plug 3, by deformation and pushing back of the material, without tearing of material.
    In the first embodiment of the invention, this piercing step is immediately followed by a step of raising the needle 15 into the rest position of the piston 14.
    The pressure conditioning process can also include a step of verifying, using an optical camera or optical fiber connected to an additional sensor (not shown in FIG. 4) disposed in the cover 4, of the integrity of the needle 15 after the step of raising the needle 15, thus making it possible to optically check whether the needle 15 is broken or not after the piercing step.
    An additional optical camera remote from the cover can check the filling level of the container 2 at the end of the pressure conditioning process to detect a possible breakage of the needle 15. In fact, during normal processing, the level of the content 12 must drop to a predetermined level, while in the event of no drilling and therefore no introduction of fluid, the level of the content 12 will not drop.
    A proximity sensor system could also monitor the presence of the complete and unbroken needle, without departing from the scope of the present invention.
    If we refer to Figure 5, we can see that there is shown the pressure conditioning device 1 during the fluid introduction step according to the first embodiment of the invention.
    In the first embodiment of the invention, the needle 15 is cylindrical and solid and has a pointed end in the form of a cone.
    The needle 15 is preferably heated by a heating means (not shown in FIG. 5), the heating of the needle 15 making it possible both to sterilize the needle 15 and to facilitate the piercing of the plastic material of the plug 3. The needle 15 is preferably heated to a temperature above 95 ° C for its sterilization and below 130 ° C to avoid possible melting of the plastic material of the plug 3 during drilling and bonding of plastic particles on the needle 15 which could then come off when piercing the plug 3 of another container 2.
    The temperature of the needle 15 is preferably maintained and constantly monitored by a resistor / probe placed in the piston 14.
    In the first embodiment of the invention, during the step of introducing fluid, the pistons 14 and 18 respectively of the needle 15 and of the heating cannula 19 are in their rest positions, the needle 15 full thus being withdrawn from the hole 23 formed in the plug 3. In this first embodiment, sterilization of the external surface of the plug 3 before the cover 4 comes into contact with the plug 3 is compulsory so as not to pollute the content 12 during the introduction of fluid into the head space 13.
    A fluid 24 is introduced into the internal cavity 22 of the cover 4 and then into the head space 13 of the container 2 via the hole 23, formed through the plug 3, using one of the inputs of fluid 6, so as to obtain a residual pressure at least equal to atmospheric pressure in the head space 13 of the container 2.
    The fluid 24 is an inert and sterile gas such as nitrogen in particular in gaseous form, which makes it possible not to cause subsequent oxidation of the content 12, after bottling. This avoids overcollapsing due to the subsequent consumption of oxygen since there is none or very little, the inert gas having largely replaced the initially confined air.
    In the case of hot filling at a temperature above 73 ° C, the fluid 24 is introduced into the head space 13 after the content 12 has cooled to a temperature below 45 ° C.
    The fluid introduction pressure 24 is configured to generate a residual pressure in the container 2, between 1.01 bars and 2.5 bars, and preferably between 1.01 bars and 1.4 bars.
    The step of introducing the fluid 24 into the head space 13 preferably comprises an introduction of fluid 24 in an initial phase at a first pressure value, then an introduction of fluid 24 in a final phase at a second pressure value lower than the first pressure value. It is thus possible to greatly increase the pressure in the initial phase of pressurization immediately after drilling, and to have a lower pressure in the final phase in order to adjust the final pressure just before obturation by fusion. .
    If we refer to Figure 6, we can see that there is shown the pressure conditioning device 1 during the sealing step.
    During the sealing step, the piston 18 of the heating cannula 19 is in its deployed position, so that the heating cannula 19 is lowered to the hole 23 formed in the plug 3 by the needle 15.
    The heating cannula 19 allows the hole 23 formed in the plug 3 to be filled, by melting the plastic material of the plug 3, which guarantees the final tightness of the container 2 while compensating for the depression in the container 2.
    The shutter step is performed within a time of between 0 and 5 seconds.
    The pressure conditioning process can also include a step of verifying, using the optical camera C arranged in the internal cavity 22 of the cover 4, the quality of closure of the hole 23 by the heating cannula 19, which thus makes it possible to optically check whether the quality of closure of the hole 23 by the heating cannula 19 is good or bad. The closure leaves on the upper surface of the cap a mark characteristic of the quality of closure by the heating cannula 19.
    Said verification step comprises the following sub-steps: the capture, by the optical camera C, of an image of the plug 3 at the level of the circular obturation formed by the hemispherical heating cannula 19; measuring the diameter of the captured circular obturation; and comparing the measured diameter to a threshold value to determine whether the shutter quality is acceptable or not.
    The optical camera C thus allows visual control of the shutter to measure the penetration of the heating cannula 19 and guarantee the quality of the weld.
    The obturation step is followed by a step of raising the heating cannula 19 to the rest position of the piston 18, then of a step of removing the cover 4 from the plug 3.
    The process according to the present invention allows hot filling in containers 2, for example in PET, with reduced grammages of the order of 15% compared to the hot filling process with deformation of the container, which is a reduction. considerable material in view of the multiplying coefficient of the number of containers 2 products.
    No particular architecture should be studied for the wall, any technical panel and / or complex petaloid background becomes useless.
    The container shapes 2 are in fact much freer and more sober, and recycling is less costly since the quantity of material used is less.
    Having the container 2 under atmospheric pressure or light pressure allows better stacking and palletizing.
    The method according to the present invention applies to all filling methods and even for pressurizing cold-filled containers 2 in a sterile environment which one would not only want to compensate for a possible reduction in the volume of the head space 13 by consumption of oxygen but also put a slight overpressure to strengthen the mechanical strength, or even inject a neutral gas to replace the air confined in the head space 13 in order to preserve all the organoleptic qualities of the products that the oxidation can alter.
    If we refer to Figure 7, we can see that there is shown the heating cannula 19 of the pressure conditioning device 1.
    The heating cannula 19 comprises a cannula end 25 (which will be described in more detail in FIG. 8) and a hollow and cylindrical cannula support 26 in which is force-fitted part of the cannula end 25, part of the cannula support 26 being force fitted into the lower part of the piston 18 which is hollow.
    A heating resistor / temperature probe 27 is disposed inside the hollow cannula support 26, the lower part of the heating resistor / temperature probe 27 being in contact with the cannula end 25, and the upper part of the heating resistor / temperature probe 27 being connected to two electric wires 28 configured to supply electrical power to the heating resistor / temperature probe 27.
    The temperature of the cannula end 25 and the contact time can be individually configured to obtain the desired penetration / welding and are continuously monitored by the pressure conditioning device 1.
    The temperature of the cannula end 25 is of the order of 140 ° C - 220 ° C, preferably of the order of 180 ° C - 200 ° C, depending on the material constituting the plug 3, to ensure rapid melting of the plastic of the plug 3.
    A minimum force, for example using a cylinder controlled at 7 bars, is applied to the heating cannula 19 to ensure a significant compression of the plastic during the melting phase to fill the hole 23. An insufficient pressure of the heating cannula 19, despite the right temperature and the right contact time, would indeed compromise the quality / tightness of the weld.
    A water cooling circuit (not shown in Figure 7) placed in the cover 4 preferably ensures that the cover 4 is kept at a "reasonable" temperature.
    Yes We are refers to the Figure 8, we that he there is represented The end cannula 25. The end cannula 25 understands a whose 1 'a faces understands a protrusion 25b
    can be seen to force fit into the cannula support 26, and the other opposite face comprises a pin of hemispherical shape 25c. It should be noted that the hemispherical shape shown is not limiting, and that any convex shape of the end of the heating cannula is within the scope of the present invention.
    The hemispherical shape of the stud 25c makes it possible to carry out a verification with precision of the quality of sealing by the heating cannula 19 of the hole 23 formed in the plug 3 by the needle 15. In fact, the sealing formed by the shaped stud hemispherical 25c is circular, which makes it possible to measure, using the optical camera C, the diameter of the circular shutter produced to determine whether or not the shutter quality is acceptable.
    If we refer to Figure 9, we can see that there is shown a needle 29 of the
    conditioning pressure 1 according to second mode of realisation of The invention. In this second mode of production of the invention, 1 ' pointed end 29a of 1 needle 29 East
    solid, and the rest of the needle comprises a longitudinal central bore 30 and two opposite lateral holes 31 connecting said central bore 30 with the outside of the needle 29 near the pointed end 29a of the needle 29.
    It should be noted that the needle 29 could also include at least three lateral holes 31, without departing from the scope of the present invention.
    In this second embodiment, the fluid injection means 6 comprise at least one fluid inlet adapted to receive the fluid 24 and to inject it into the central bore 30 of the needle 29 at the end of the needle 29 opposite the pointed end 29a. The needle 29 is held in the hole 23 during the step of introducing fluid, the introduction of fluid taking place through the central bore 30 and then the two lateral holes 31.
    An introduction of the fluid 24 into the head space 13 of the container 2 is thus carried out while the needle 29 is still in its piercing position, the fluid 24 being diffused laterally in the head space 13 through the two lateral holes 31, thus making it possible to avoid possible turbulence of the content 12 and splashes during the introduction of fluid. This second embodiment also makes it possible to avoid prior sterilization of the external surface of the cap.
    3.
    The device, method and machine according to the invention can be implemented in a production line, with one or more stations upstream or downstream, in which case a conveying device will transport the container to the station on the line of production implementing the invention.
