    DEVICE FOR PACKAGING AND DISPENSING A PRODUCT, WITH BOTTLE AND METERING CAP WITH FILTER
    TECHNICAL FIELD OF THE INVENTION
    The present invention relates to the technical field of packaging of fluid products, and more particularly to that of packaging and distribution of a semi-fluid or suspended liquid product intended to be stored in a sealed and sterile manner, typically without the addition of a preservative, and to be dispensed in the form of precise unit doses using a dispenser assembly provided with a nozzle.
    The invention more particularly relates to a device for packaging and dispensing a sterile product, and which comprises:
    - a container intended to contain the product to be dispensed, and
    a metering assembly suitable for dispensing a dose of the product, this metering assembly or head comprising a dispensing end for dispensing the portion or dose of the product, and a mounting interface provided with a portion for fixing the assembly of dosage on the container.
    TECHNOLOGICAL BACKGROUND OF THE INVENTION
    Such devices are known, patent FR 2873358 (see also its equivalent EP 1773676) describing for example a device whose metering nozzle is of the type without air intake. The dispensing is actuated by a pressure exerted against a flexible wall of the container. The plastic container is typically obtained by injection molding. After the distribution, the air renewal results from a pressure rebalancing allowed via an air inlet orifice (rebalancing to compensate for the depression created by the distribution of a dose of product). The air inlet port is placed in the bottom of the container or in the nozzle, and is associated with a filter element. The filter element is used to sterilize the incoming air.
    The actuation of the dispensing is not necessarily very precise with this type of device, the actuation area being very far from the dispensing end of the nozzle.
    Patent FR 2873358 describes a valve associated with the filter and operating in such a way that it can allow air to enter the bottle and oppose any air or liquid outlet to the outside of the bottle.
    In devices having this type of complex dispensing head, actuable by pressing on the nozzle, the air intake assembly is formed on the side of the bottom of the container.
    However, the combination of the filter element and the bottle implies that the bottom must be rigid and of precise dimensions, which in practice limits its manufacture to injection molding of plastics.
    With this type of device integrating the filter into the bottom of the bottle, the demolding operation requires that the container be of cylindrical shape and provided with a unblocking collar whose dimensions are sufficiently large. This limits the possibilities of marketing the device.
    Thus, this type of device is not simple to miniaturize.
    The large dimensions of the unblocking neck which must necessarily be at least equal to those of the inside of the body of the bottle so that it can be removed from the mold impose large dimensions of the dispenser assembly so that it adapts to the dimensions of the collar. The importance of these dimensions leads to an increase in the manufacturing costs of the parts that this dispenser contains.
    Another drawback of existing devices lies in the fact that the filter is a source of brittleness. Deterioration of the filter by an external action (involuntary or not) renders the device inoperative.
    Another drawback of the existing devices lies in the fact that the renewal air inlet orifice being in the bottom of the bottle, the latter can be blocked or the filter clogged by the simple contact with a liquid making the renewal of looks ineffective.
    Another drawback of existing devices lies in the fact that the renewal air intake orifice being located in the bottom of the bottle, the latter allows communication from the inside of the bottle with the outside atmosphere thus allowing variations pressure which is detrimental to the proper functioning of the device and which may cause the liquid to leak to the outside of the bottle.
    There is therefore a need for reliable devices which are compatible with mass production methods, at least with regard to the bottle, typically by allowing:
    - the use of plastic bottles of any shape, not necessarily cylindrical, and / or
    - The use of bottles made of a material other than plastic such as glass or aluminum for example, and / or the manufacture of the neck of the bottle in dimensions independent of the shape of the body of said bottle.
    Alternatively or in addition, it would be desirable for the devices of the aforementioned kind to be provided with a dispensing accessory adaptable to the neck of the bottle in dimensions as small as possible and therefore of a cost much lower than that of the existing devices.
    More generally, the object of the invention is to remedy the drawbacks of similar devices of the prior art and to propose such a device which is better suited to the various requirements of the practice than the known devices.
    GENERAL DESCRIPTION OF THE INVENTION
    The invention aims to improve the situation, in P a lli an t one or more of the aforementioned drawbacks.
    To this end, there is proposed according to the invention a device for packaging and dispensing a product, generally liquid or gel (for example a generally liquid semi-fluid composition or a mixture with suspended particles), the device comprising :
    - a container delimiting an internal volume and intended to contain the product,
    - a dispensing head, provided with a dispensing end and an actuating part, for dispensing a portion or dose of the product;
    - A mounting interface, belonging to the dispensing head and adapted to be fixed on the container by an annular fixing portion;
    - an air renewal and filtration assembly, the air renewal and filtration assembly comprising an external air intake orifice and a non-return valve allowing the air entering through the external orifice to enter the interior volume after dispensing a product;
    with the particularity that the external orifice is formed at a distance from a bottom of the container, the air renewal and filtration assembly comprising a filter element which is:
    mounted in the dispensing head;
    - placed in an air circulation duct which extends between the external orifice and the non-return valve; and at a distance and offset inwards with respect to at least one of the container and said annular fixing portion.
    According to a preferred option, the shape and dimensions of said accessory do not depend on those of the container neck (or similar end of the container), the air renewal and filtration assembly being positioned inside the accessory forming the dispensing head so that it is not accessible from the outside, said assembly being able to be closed by fitting a cover.
    With this arrangement, the air renewal assembly is advantageously isolated inside the bottle, making it inaccessible to any external action which may either damage it or make it inoperative.
    The arrangement of the filter element at a distance from the container is, of course, an arrangement at a non-zero distance (which means that there is a spacing visible to the naked eye if the device were cut).
    This also reduces the size. The dispensing head can be longer axially than wide, in an option.
    In one embodiment, the dispensing head is axially tapered (narrower) on the side of the dispensing end, opposite the container. The device thus has a compact head.
    Advantageously, the device is of the type that can be actuated by pressure on one side of the dispensing head and / or by any type of compression of at least one metering chamber. Thus, the non-return valve allows air previously filtered by the filter element to pass into the container, only after a portion or dose of product has been dispensed by compression of the metering chamber or chambers.
    By using a simple cover, it is also possible to isolate the interior of the bottle or container from variations in external pressures. Indeed, the cover can seal off the access to the external orifice (where the air circulation duct opens).
    Optionally, the filter element can be a simple disc of fibrous material.
    In one option, the filter element comprises a hydrophobic material or is made of a hydrophobic material.
    According to one feature, the external orifice is formed in the dispensing head, outside the actuating part.
    According to one feature, the container has an opening opposite the bottom, and a side wall extending around a longitudinal axis, the mounting interface being fixed on the container on the side of its opening and extending from annularly around the longitudinal axis. The fixing portion is annular to define a sealed, preferably radial, annular contact against the container.
    According to one feature, the container is formed in one piece.
    Optionally, the wall of the container is less compressible than the actuating part and preferably rigid.
    The container forms an external face of the device, all or part of the external face being adapted to allow the gripping of the device.
    Optionally, the duct opens radially outward, and / or the air circulation duct comprises a section which extends radially between a portion of duct, preferably bent, including the external orifice and a bent zone located upstream of the filter element according to the incoming air flow direction.
    More generally, a typically narrow section can be provided, which extends from the external orifice to a bent or deflection zone, preferably located upstream of the filter element according to the incoming flow direction of the air.
    With this arrangement, the filter is not opposite the external outlet of the duct, which improves its protection.
    The direction of filtration can be an axial direction, optionally parallel to the general direction of air injection into the interior volume in an open side of the non-return valve. This arrangement allows significant miniaturization.
    Alternatively, the filtration can be carried out at least in part in a radial direction, for example centripetal. A configuration with centripetal filtration can optimize the surface of filter media on the upstream side, especially when the filter media has an annular conformation. Such an option can be provided when it is desired to guarantee a very high quality of filtration.
    According to one option, the external orifice forms a lateral outlet of the air circulation duct through an external wall of the dispensing head, a cover preferably being provided to cover the dispensing head and the external orifice.
    Preferably, the cover defines a tight annular contact against the mounting interface, complementary to a tight annular contact of the fixing portion against the container, in a hermetic storage configuration (with the cover mounted and fixed on the interface of mounting). At least one of these contacts, preferably the two contacts, are made in a continuous zone of radial contact.
    According to another option, the air circulation duct comprises a section which extends axially between:
    - the external opening;
    - And a duct widening zone, located upstream of the filter element in the direction of incoming air circulation.
    Provision may be made for the external orifice to form an axial outlet for the air circulation duct through the dispensing end, the duct possibly being formed by a rigid tubular element formed in one piece.
    In various embodiments of the device according to the invention, one can optionally have recourse to one and / or the other of the following provisions:
    the filter element is placed in the interior volume or on the side of an internal face of the dispensing head which extends opposite the axial dispensing end.
    the filter element is positioned internally in a hollow of the non-return valve.
    the air circulation duct comprises a narrow section extending between the external orifice and an enlargement zone formed by or communicating with the central cavity.
    the partition element comprises a base (optionally transverse) and a longitudinal extension formed in one piece.
    the non-return valve comprises an elastically deformable part which forms a valve extended by a female element, the female element being tightly connected to a male tubular portion belonging to the dispensing head.
    the male tubular portion is part of a partition element which separates said interior volume from a metering chamber, the male tubular portion being integrally formed with a rigid internal rod of the
    distribution head which extends to the end of distribution (thus a single piece can form the conduit).- the check valve is a valve beak of duck.the device includes a hood fixed at 1'interface mounting and covering the head of distribution, , the hood being configured to shut off
    the external orifice (in a sealed manner).
    the non-return valve has a valve formed integrally with a tubular fixing portion, this tubular fixing portion surrounding and connecting by a radial annular contact against an external face of a tubular connection formed by the partition element.
    the dispensing head has two metering chambers, preferably distributed symmetrically on either side of a median XY plane (separating two container halves), this XY median plane comprising the central X axis of the container and a Y axis perpendicular to the X axis and perpendicular to a Z axis defining the direction of thrust on the actuating part associated with each metering chamber.
    the dispensing head includes a metering chamber and a partition element separating the metering chamber from the interior volume, a central cavity being formed by the partition element (the latter having for example a cylindrical or annular conformation) to allow accommodation and / or attach the filter element, the central cavity constituting all or part of one end of the air circulation duct.
    the dispensing head is adapted to dispense a portion or dose of the product in response to a pressure exerted on the actuating part.
    - The thrust is typically carried out on a flexible part of the dispensing head, the head having a rigid part which remains stationary relative to the container and which delimits (in part) the metering chamber; thus, the device makes it possible to distribute portions or doses of product by simple pressure on the flexible part of the endpiece with which the accessory is provided, and to compensate for the depression thus created in the container by an air intake, preferably sterile, through the renewal and filtration assembly positioned inside said accessory so that it can be isolated from the outside.
    Advantageously, the accessory (forming the dispensing head) in which the air renewal and filtration assembly is positioned consists of two parts molded separately and assembled in leaktight manner, one of which flexible allows the distribution of '' a dose of product by compressing a metering chamber and opening its end by spreading the other corresponding rigid part, and said other rigid part comprising in its center the filtration and renewal assembly of the air composed of a filter and a valve making it possible to isolate the filter from the liquid, and a channel for the arrival of the renewal air situated either laterally or axially.
    According to a particular feature, the filter element is a sterilizing filter medium.
    Optionally, the filter element cooperates with a one-way passage valve, allowing outside air to enter the interior volume of the container (by joining a free space in the container which is complementary to the product), but not allowing liquid product to escape to the outside of the container, or to be in contact with the filter element.
    The device according to the invention can be used for the packaging of drops of a product for ophthalmic use or for other applications requiring the delivery of precise doses of a product stored sterile in the container.
    The container is preferably made in one piece.
    The container may be made of glass.
    The mounting interface is optionally formed by an adapter ring (allowing adaptation to a variety of containers without modifying the structure of the functional parts of the accessory).
    Other characteristics and advantages of the invention emerge from the description given below, with reference to the appended drawings, which represent, by way of non-limiting examples, embodiments and implementation of the subject of the invention. In these drawings:

    - Figure 6 is a schematic view in axial section of a device according to an alternative embodiment, showing the circuit for the supply of replacement air through a central channel, the filter and the valve.
    - Figure 7 is a schematic view in axial section of a device according to Figure 1 on which is positioned a cover closing the inlet opening of the renewal air.
    As shown in FIG. 1, the packaging and distribution device 100 comprises a container 1 in which the product to be dispensed 2 is contained, and a dispensing accessory or dispensing head 7 composed of a rigid part 3 cooperating with a part flexible 4, all of these parts 3, 4 delimiting the metering chambers 5. In the nonlimiting example illustrated in FIGS. 1 and 2, the metering chamber or chambers 5 can be situated completely outside the internal volume V delimited by the container 1. A partition element including or forming the rigid part 3 can form a separation between the internal volume V and the metering chambers 5. The side wall of the container 1 extends around a longitudinal axis X (forming typically a central axis of the device 100) which can pass through the axial end 7a where the dose or drop 14 is expelled.
    The end 7a of the flexible part 4 cooperates with the end 6 of the rigid part 3 in order to allow the product contained in the chambers 5 to be expelled from the interior of said chambers 5 when the latter are compressed but not allowing outside air not to enter said chambers 5 when they are no longer compressed. The actuation of the dispensing is enabled by at least one actuation portion 7b, formed for example laterally on the dispensing head 7. The actuation portion 7b is movable by depressing, in the manner of a push button.
    In the nonlimiting example of FIG. 5, each chamber 5 extends between the rigid part 3 (internal side) and an internal face of the flexible part 4 radially spaced from the rigid part. While the distribution head 7 has no air intake opening in the lateral zone covering the metering chamber (s) 5, the distribution head 7 is however provided with an external orifice 10, 10 ′, allowing a pressure rebalancing after dispensing a dose, as clearly visible in FIGS. 4 and 6. Such an orifice 10, 10 ′ is located on the side of one end of the dispensing head 7, ie in the mounting interface 27, or surrounded by the end 7a situated opposite the mounting interface 27, in the axial extension of the metering chambers 5.
    The device 100 also includes a non-return valve 8 allowing the product 2 to flow from the interior of the container 1 to the chamber or chambers 5 but not allowing said product to return from the chambers 5 towards the interior of the container 1, a renewal air filtration assembly comprising a sterilizing filter or similar filter element 11 associated with a non-return type valve 12 which allows outside air to penetrate inside the container 1 but prevents any air or product outlet 2 from inside to outside of container 1.
    The content of the interior volume V thus remains sterile when the filter element 11 is of sterilizing grade or with sufficient barrier / screen effect. This type of filter element 11 is for example composed of polymers having pores of submicron size, for example of the order of 0.20 or 0.22 μm. To avoid any risk of clogging, the filter element 11 or a feed zone upstream of this filter element 11 may include a pre-filter.
    It is understood that the external orifice 10, 10 ′ can be formed at a distance from the bottom 1a of the container 1, just like the assembly (11, 12) for renewing and filtering the air which includes the filtering element 11. In a preferred embodiment, the filter element 11 is mounted in the dispensing head 7 by being placed in an air circulation duct 16 or 16 ′ which extends between the external orifice 10 or 10 ′ and the non-return valve 12. The filter element 11 is for example inserted in a central cavity formed by the partition element which covers the interior volume V. The cavity here forms an enlargement zone of the conduit 16. The valve 12 can close this central cavity. Optionally, the valve 12 envelops all or part of the filter element 11, for example so that the filter element is placed internally in a hollow of the non-return valve 12.
    The filter element 11 extends at a distance and can be offset inwardly with respect to at least one of the container 1 and the fixing portion 20 allowing a snap-fastening of the container 1 with sealing or similar sealing fixing portion between the dispensing head 7 and the container 1.
    The valve 8 can be fixed to the mounting interface 27, so that it is completely distant from the container 1, and preferably located outside of the interior volume V. It can be seen in the drawings that this valve 8 (distant from the longitudinal axis X) may be closer to the annular fixing portion engaged with the container 1 than is the filter element 11, the latter being closer to the longitudinal axis X.
    The device 100 as shown in Figures 2, 3, 4 and 5 operates as follows.
    According to FIG. 2, a pressure exerted on the flexible part 4 (typically by targeting the actuation portion or portions 7b) according to the arrows A and A 'compresses the product contained in the chambers 5 and expels said product towards the outside of the device 100 via the end 7a of the flexible part 4 which departs from the end 6 of the rigid part 3 then returns to its initial position under the effect of its own elasticity after releasing a drop 14 of product.
    Optionally, the dispensing head 7 has two metering chambers 5 as in the example in FIGS. 1 and 5. These two chambers 5 are preferably distributed symmetrically on either side of a median XY plane (separating two container halves), this median plane XY comprising the central X axis of the container 1 and a Y axis perpendicular to the X axis and perpendicular to a Z axis defining the direction of thrust on the actuation part 7b associated with each chamber dosing 5.
    According to FIG. 3, the flexible part 4 returns to its initial position according to the arrows B and B ′ when the external pressure exerted ceases, creating a vacuum inside the chambers 5 which causes the valve 8 to open and the passage of the liquid 2 from the inside of the container 1 towards the inside of the chambers 5 through the orifice 9 along the arrow C (with a flow substantially parallel to the axis X, along the central rod belonging to a rigid part 3 of the dispensing head 7).
    The passage of a part of the product 2 towards the interior of the chambers 5 has the effect of creating a depression in the free part 13.
    Figure 4 shows the flow of renewal air to compensate for this depression. The outside air enters the container 1 through the orifice 10 of the lateral channel defining the duct 16, along arrow D, then through the filter element 11 along arrow D 'and of the elastic valve 12 which opens under the effect of the relative overpressure of the renewal air. When the vacuum existing in the free part 13 is compensated by the arrival of the renewal air, this air intake ceases and the elastic valve 12 returns to its initial closed position preventing any contact between the filter element 11 and the product. 2 and preventing any exit of said product 2 from the inside to the outside of the device 100.
    FIG. 6 shows the path of the renewal air represented by the arrows E and E 'according to the same principle as that described above but through the orifice 10' of an axial channel forming the conduit 16 'for circulation d 'air.
    FIG. 7 shows the device 100 at rest after the installation of a protective cover 15. Said cover 15 closes the end (orifice 10) of the channel or conduit 16 by cooperating in a sealed manner with the accessory 7, in preventing any communication between the interior of the device 100 and the exterior.
    With reference to FIG. 7, it can be seen that the cover 15 defines a sealed annular contact C2 against the mounting interface 27, complementary to a sealed annular contact C1 of the fixing portion 20 against the container 1, in a configuration hermetic storage (with the cover 15 mounted and fixed on the mounting interface 27). At least one of these contacts, preferably the two contacts C1, C2, are made in a continuous zone of radial contact.
    The cover 15 can make a sealed contact C3 against an external shoulder or simi 1 external surface of the dispensing head 7, in order to prevent the air 25 trapped under the cover 15 from communicating with the intake orifice d air 10, in a peripheral zone around the mounting interface 27 where the conduit 16 opens (via the orifice 10).
    The device 100 thus represented comprises an air renewal assembly comprising a filter element 11 located at a location inaccessible from the outside, thus guaranteeing its perfect integrity.
    The shape and dimensions of the dispensing head 7 or similar accessory completing the container 1 does not depend on those of the open end (typically the neck) of the container 1. The coupling of the renewal and filtration assembly of the air (11, 12) with the dispensing head 7 is compatible with a reduction in the size of this head 7 (less bulk) and makes it possible to hide / protect the filter element 11, which makes the device 100 more reliable ( minimizing the risk of alteration).
    Other embodiments are possible without departing from the scope of the invention. Thus, it is possible to produce such a device 100 comprising only a single metering chamber 5, or one or more metering chambers of a shape different from that shown in FIG. 5, such as for example a metering chamber as described in FIG. Patent EP 1773676.
    Also, a metering chamber defined in the accessory forming the dispensing head 7 can extend at least partially inside the interior volume V of the container 1, in alternative embodiments.
