    Hand operated applicator suitable for gun valve containers
    SCOPE OF THE INVENTION
    This invention relates to containers, cans or cans containing a compound under pressure, in particular disposable containers, in the first place those provided with a gun valve so that the container can be coupled to an apparatus, which is typically referred to as a dispensing gun , to apply the compound. The compound is usually reactive and curable, may contain one or more active ingredients, and may be suitable for forming, for example, a seal (e.g., silicone paste), a polyurethane (PU) foam, or a two component adhesive. The invention relates in particular to providing an improved hand-operated applicator to also allow safe and easy hand-operated use for such gun valve containers.
    BACKGROUND OF THE INVENTION
    Containers under pressure, which contain compounds such as pastes, foams or adhesives, are increasingly being used in the construction industry as well as in DIY activities. These containers are usually disposable containers, closed by a relatively simple valve, but which must nevertheless be able to withstand the important pressure that can occur inside the container.
    The containers themselves are usually made of metal and are usually cylindrical in shape. The bottom is usually formed by a plate, with a flange attached to the cylinder, and is usually concave to withstand the internal pressure while maintaining the ability for the container to stand upright on a flat surface. The top is usually provided with a container head, also with a flange mounted on the cylinder, and which is usually convex for the same reason of the higher pressure resistance. A filling opening is usually provided centrally in the cylinder head. When preparing the container for the market, the empty container is usually filled with the compound via this central filling opening in the head, which can then be closed by flanging the container valve onto the filling opening. Many compounds can be filled into the container under atmospheric pressure, and a higher pressure can then be built up or introduced into the container, usually after it has been sealed as described. An example where the pressure builds up after the container is closed are the polyurethane foam connections, in particular one-component foam (OCF), in which, after filling the container, an exothermic chemical reaction between the compounds can be started , such as by shaking the container, and the reaction produces heat and builds up the pressure through chemical production and / or the evaporation of propellants. Propellants for building up the pressure can also be introduced at the time of filling the container, such as a cold liquid, which can then evaporate after the container is closed.
    Two types of applicators are generally used in current practice. Occasional and do-it-yourself users generally prefer a simple hand-operated applicator, usually also a disposable one, which is usually screwed onto the stem of the container valve and which usually comprises a hose or tube for guiding the flow from the compound to the intended location (also called "a straw"), and a tiltable adapter or lever. The container valves for such hand-operated applicators have a threaded stem on which the applicator is screwed, and can be referred to as "straw valves." Such hand-operated applicators are characterized in that they do not themselves have a valve for stopping or controlling the flow of compound, but for this purpose act upon the valve provided on the container.As a result, all compound that has already passed through the container valve and the manual applicator invaded, is exposed to the atmosphere, and can, if susceptible, continue to react and in its final and usually For these reasons, these adapters are simple in design and production, inexpensive, but usually only usable once, and therefore to be discarded afterwards.Typically, acting on the tiltable adapter or lever provided as part of the manual applicator in a tilt of the stem of the container, such that one or more openings in the stem of the valve are at least partially released into the contents of the reservoir, and thereby open the straw valve. The assembly is such that the user can hold the container and at the same time press the handle of the manual applicator, which provides a rough way of controlling and dosing the compound flow. US Patent 4165825 describes suitable valves for such manual operation applications. However, the dosage of a compound with such manual control systems is rather inaccurate, and such a system is therefore more suitable for filling large gaps or cavities, such as those wider than 2 cm.
    A variety of handheld or handheld applicators are known in the art. All of these applicators connect to the straw valve via a screw connection to the threaded section that is always provided on the stem of the valve with a straw valve, and open the valve by tilting the stem of the valve. They are therefore specific and only suitable for containers with a straw valve. They therefore retain the disadvantage that the dosage of the compound remains difficult to predict and control, e.g. because the position of the lateral openings at the bottom of the stem is unpredictable with respect to the direction of tilting. These hand-operated applicators are usually only provided with a handle to tilt the stem of the valve by pushing the handle with the fingers of the hand, and require the palm of the hand to engage with the container itself. The disadvantage of such systems is that, during hand intervention, the bonding bond between the applicator and the container is tensioned, and usually in a direction that creates a risk that the bond would loosen and creates a risk that the compound would inadvertently be released .
    The more intensive users, such as professionals or more experienced do-it-yourself users, usually prefer a more sophisticated dosing device, such as a dosing gun, for applying the compound, such as a foam compound. With such dosing devices, the user holds the device or dosing gun and handles the device or dosing gun with the compound container attached to the gun. Such guns are characterized in that they contain their own valve, preferably a needle valve for higher accuracy and better closure, for stopping or controlling the flow of the compound, and this valve is usually located at the tip of the gun barrel and is much more advanced than the container lid. It usually permits a much better control of the flow of the compound compared to the container valve. Because the gun control valve is at the tip of the barrel, the compound in the dosing gun remains under pressure and sealed off from the atmosphere. Thus, after use, little or no volume of the compound remains that has been exposed to the atmosphere and could react, become stiff and affect the operation of the gun for subsequent use. The compound inside the gun can only be exposed to the atmosphere for the short time required to exchange a container on the dosing gun. This time is usually short, and the dosing gun is usually used immediately after the exchange, so that the compound within the dosing gun is refreshed and after use this new compound remains under pressure and fresh in its liquid state. These dosing guns are usually complex and expensive and are usually reused several times after replacing the previous empty container with a fresh and full one. The use of these dosing guns is more comfortable for the user, and allows higher accuracy and dosing when applying the compound than the manual control system. Dosing guns are therefore also preferred for filling in smaller gaps, such as those smaller than 2 cm wide. The higher dosing accuracy makes it possible to work with less redundant compound, which usually has to be removed later and ends up as waste. This reduces the amount of aftercare work required and entails greater material use efficiency. Both advantages are of great importance for the professional or the intensive user.
    Containers intended for the intensive user are conveniently provided for this purpose in an assembly with a first coupling piece, usually made of a plastic material, which makes the container suitable for attachment to the dosing gun or dosing device, and which corresponds to a connecting element integrated in the dosing gun or with a second coupling piece attached to the dosing gun, also referred to as a gun adapter, usually made of metal, such as aluminum or bronze, for establishing the connection to the dosing device or dosing gun. A suitable foam dispensing gun is described, for example, in US Patent 5,271,537, wherein the device comprises a screw connection into which a container can be screwed, which has a suitable screw connection, usually by means of a suitable coupling piece on the container. A particularly useful first coupling piece for such screw connections is described in our pending European patent application EP-A-10164924.2, filed on 4 June 2010. Instead of a screw connection, the container and the dosing gun can be connected by means of an even more convenient and safe bayonet type coupling, also known as the "Click & Fix" coupling, as described in WO 98/43894. An improved first coupling piece for such Click & Fix coupling is described in our pending European patent application EP-A-10164927.5, filed on June 4, 2010.
    The containers themselves, which are intended for intensive use with a dosing gun, are closed with another type of valve, also known as a gun valve to distinguish them from the so-called straw valve described above, and which is more suitable for this type of use. The gun valve does not include a threaded section that the straw valve requires for screwing the manual control adapter onto the valve stem. Many gun valves are also not made to be tilted. The piston valve is built to be fully opened by coupling the container with the pistol by pressing the stem of the valve down into the contents of the reservoir, thus offering as much opening as possible for a relatively small movement of the stem. Another difference between the two types of valves is that the straw valve is provided with an extended stem, provided with a threaded section for screwing on the hand-operated applicator. This connection between the stem of the straw valve and the associated hand-operated applicator must be strong enough such that it allows the transmission of the force of an intervention on the hand-operated applicator such that the straw valve is tilted and thereby opened. Gun valves are not designed to be tilted, and therefore do not have a stem extension or a threaded section. Consequently, straw valve containers cannot be used with equipment designed for gun valve containers. Gun valves are designed to be opened by depressing the stem in the container, by a movement along the axis of symmetry of the stem of the valve.
    Therefore, due to the different valves used to close the containers, the container or canister intended for use with the dispensing gun is usually different from the container intended for manual operation, i.e. with a manual applicator. Accordingly, the supply chain maintains two types of containers with different designs, one designed for use with the dosing gun, i.e., gun valve containers, and the other for use with the manual applicator, i.e., straw valve containers. The manual applicators are also specially made to work with the straw valve. The threaded connection is incompatible with gun valves, and the known hand-operated applicators designed for straw valve containers are unable to work on a gun valve container.
    Thus, there is a need for a manual applicator that would be suitable for use with the gun valve container, ie a container intended for use with the dispensing gun, and which is sealed for that purpose with a gun valve.
    WO 2007/112758 describes a hand-operated applicator that can be mounted on the valve stem of a conventional gun valve. The manual applicator can be "clicked" directly onto the valve stem. By pressing a lever that is provided as part of the manual applicator, the stem of the valve is tilted and the valve is opened. The difficulty with this design is that attaching the manual applicator to or separate from the valve stem must be performed very carefully, because any unintended tilting of the valve during this operation would cause premature and unintended spread of the compound and any damage to the valve can lead to a safety risk.
    US 2007/0181610 A1 describes a hand-operated applicator suitable for being clicked on the flange around a gun valve. In an embodiment illustrated by Figures 3 and 4 in US 2007/0181610 A1, the applicator is provided with a gripping ring with a circumferential groove that can be pressed onto the pleated lip of the dome of the bushing, that is to say on the flange which container valve, or more precisely the valve plate thereof, connects to the container head. This flange connection is made by crimping the container valve on the container head, which usually also closes the container after it has been filled. The applicator described is further provided with a safety plate, which prevents accidental opening of the valve until the safety plate has broken off from the applicator. A disadvantage of this proposal is that the assembly of the applicator with the container offers the same ergonomics of a conventional manual operator applicator assembly during use. Another drawback is that the removal of the safety plate is irreversible. Once broken off, the accidental opening protection cannot be reinstalled. Another disadvantage is that the hand-operated applicator of US 2007/0181610 A1 does not comprise a compartment for storing, for example, protective gloves, useful for the user for protecting his hands against contact with the contents of the container.
    WO 2009/147250 describes another hand-operated applicator for use with gun valve containers of various sizes. This applicator is an assembly of at least 3 separate pieces, namely the jacket, the adapter, a connecting piece, and the handle. During operation, the adapter moves vertically and must provide a seal with the head of the valve stem. The adapter is described as an interchangeable part, such that with different adapters the same applicator can be suitable for different types of valves. The connecting piece connects to the sprayer or hose. While using the container with the head down, this trunk comes down under the hand of the user. The applicator is equipped with a removable safety lip for locking the handle. A disadvantage of this applicator is that it comprises at least 4 parts that must be produced separately and then assembled. Another drawback is that it requires an adapter suitable for the type of valve for which it is intended, and an assembled applicator is only suitable for a certain type of valve. Another disadvantage is that the trunk comes under the hand, which is difficult to aim accurately. Another disadvantage is that the removal of the safety lip is irreversible. Once broken off, the accidental opening protection cannot be reinstalled. Another disadvantage is that the manual applicator of WO 2009/147250 does not include a compartment for storing an accessory object, e.g. protective gloves, useful for the user for protecting his hands from contact with the contents of the container.
    Hand-operated applicators for use with gun valve containers are also described in US 5215225, US 5549226 and WO 2009/004097. However, these applicators also have the same disadvantages as the applicator described in US 2007/0181610 A1 and which are discussed in more detail above.
    The containers of the present invention can include compounds under pressure, which are still highly reactive and further react after the compound has been applied to its final location, such as in a gap or on a substrate. Contact of the contents of the container with the skin, or even more important with the eyes, should therefore be avoided. For safety reasons, the container valve and in particular the stem of the valve must be protected against damage, tear or contact and displacement relative to the valve bowl. Separate hoods are designed, and the head of connectors that are clicked onto the containers can be fitted with hoods to close the valve compartment. When a gun valve container is not intended for delivery with a clicked-on coupling piece, but rather with a manual applicator, adequate measures must be taken to properly protect the gun valve from damage, tear or contact and displacement relative to the valve bowl .
    Thus, there remains a need for a manual applicator for gun valve containers that provides improved ergonomics over conventional manual operation, offers dosing and aiming capabilities comparable to those of a dispensing gun, and can be produced simply and cheaply as one single product in a single production step. That applicator is preferably provided with a reversible safety seal, more preferably also as an integrated part.
    The present invention has for its object to obviate or at least to limit the problem described above and / or to provide improvements in general.
    SUMMARY OF THE INVENTION
    According to the invention there is provided a manual actuator in an assembly of a pressure container therewith, a method for its production, and the associated uses, as defined in the accompanying claims.
    The invention provides an assembly of a pressure container containing a composition suitable for forming a silicone paste, a polyurethane (PU) foam, or an adhesive, wherein the container is sealed with a container valve that is a gun valve, and a manual actuator suitable for applying the contents present in the pressure container, characterized in that the manual applicator comprises a fixed part for attachment to the pressure container, and which fixed part further provides a grip surface for contact with the palm of the hand, the fixed part a forming the pistol grip, and that the hand-operated applicator further comprises an integrated movable member which provides a lever surface for engaging at least one finger of the same hand, preferably by two and more preferably by three fingers of the hand, and further provided by its movement for engaging the container valve and through the action for opening the container container valve by pressing down the stem of the container valve into the contents of the reservoir, by a movement along the axis of symmetry of the stem of the valve.
    We have found that the hand-operated applicator of the present invention provides excellent ergonomics to the user, and is very simple and intuitive to use for non-experienced end users. A particularly advantageous feature is that the hand-operated applicator not only provides a lever surface for the engagement of the finger or multiple fingers, but also a grip surface for contact with the palm of the hand. With both surfaces integrated in the same applicator, it is avoided that acting on the applicator would put the connecting connection between the applicator and the container under voltage. As a result, the risk is considerably reduced and usually eliminated that the manual applicator inadvertently comes loose from the container during the incorporation, and the compound would inadvertently be released in relatively uncontrollable and potentially dangerous directions for the user. This entails a considerable extra safety feature.
    The hand-operated applicator offers the additional advantage that it can be produced as a single piece, eliminating complex and expensive assembly steps, and therefore it can become available at a low cost. The applicants have further found that the manual applicator can be designed such that the flow of the compound can be controlled by applying more or less force to the applicator, and this without any set screw. It has further been found that the excellent ergonomics of the hand-operated applicator and its design can offer the user improved targeting and dosing capabilities, which broadens their suitability over a wider range of applications. The assembly can thus also be suitable, for example, for filling smaller gaps with PU foam, and allows the reduction of the amount of surplus compound, which is usually applied and which must be removed later and thus ends up as waste. This reduces the amount of aftercare work required and entails greater efficiency in material consumption.
    In yet another embodiment, the invention provides a method for producing the hand-operated applicator as part of the assembly of the present invention comprising a step of injection molding, preferably only a single step of injection molding.
    The production process according to the present invention is simple and fast, and is capable of producing the hand-operated applicator at a low cost.
    In a further embodiment, the invention provides for the use of the assembly according to the present invention for applying the compound from the pressure container with a manual operation method.

    DETAILED DESCRIPTION
    The containers for compounds under pressure are usually designed as cylinders. The bottom is usually sealed by a concave bottom plate that is flanged on the cylinder. The top of the cylinder is usually closed by flaring up a convex head plate, with a central opening therein through which the container can be filled with its contents. This opening is then usually closed with a valve, whereby the contents of the container can be released with the aid of the pressure that is built up in the container. This container valve is usually also flanged on the container head. This flange connection of the valve is formed by crimping the container valve on the container head, whereby the container is usually closed at the same time after filling.
    At room temperature, the pressure within a filled and ready-to-use container is typically about 5 bar overpressure. The containers are usually able to remain intact up to a pressure of 18 bar overpressure, and are designed not to burst until a pressure of below 21.6 bar overpressure. The valve is usually designed to withstand a pressure of at least 22 bar overpressure. Other containers exist, which are only able to remain intact up to a pressure of 12 or 15 bar excess pressure. The container valve usually consists of a valve cup, ie. a round metal cup which is flanged or "shrunk" along its circumference at the central filling opening of the container, optionally in addition with the aid of a rubber seal, usually an O-ring, to prevent leakage of any contents via this valve flange.
    In the conventional valve design, the valve cup supports a central rubber seal, gasket, or "grommet" through which a generally plastic stem protrudes from a valve. The stem is usually stiff and has a central conduit which, just before the stem ends at its lower end, turns into a blind flange, laterally, into one or more, usually four, side openings. In a state of rest, the rubber gasket pulls the blind flange. against the bottom of the gasket and thus seals the openings. The valve is designed to be opened by depressing the stem relative to the gasket or cup, with the gasket usually deforming elastically and wherein at least one of the side openings in the stem of the valve becomes available for the container contents.
    Because the rubber of the gasket of the conventional valve, especially when carbon powder is used as a filler in the rubber, allows diffusion of water, which can then react with certain compounds in the container to form a sticky solid, the conventional valve the drawback that the stem of the valve can become clogged over time, or when the container is in a horizontal position for a while. This can already happen when the container is on its side for a period of only 3 to 6 weeks. Another disadvantage is that the rubber of the seal also allows the diffusion of propellant gases outside the container, such that the container can lose most or all of its pressure after a while. For these reasons, other types of valves have been developed which should not include a rubber gasket as described for the conventional valve. Such container valves can also be referred to as "feststof" valves, and suitable variants thereof are described, for example, in WO 2009/004097, US 5,014,887, WO 03/062092, or the United States patents 5215225, 5549226 and 6058960. These valves do not have a rubber seal , or just a rubber seal on the outside of the valve that does not come into contact with the contents of the container. These "feststof" valves can therefore be characterized in that the materials of the valve parts that come into contact with the contents of the reservoir are virtually impermeable to water and / or propellant gases. The valves can for instance be provided with one or even more than one metal springs , being a coil spring or a leaf spring or a combination thereof The spring or springs can be provided and adjusted in such a way that the valve can be opened more easily than a conventional valve, and thus offers a further improved ergonomics to the user, as well as an improved directional and dosing capability The springs can also provide a faster closure of the valve as compared to the conventional valve A valve with an internal coil spring is described, for example, in US 5,014,887 Valves with external coil springs can be found as part of the family of the valves MIKAVent PU-RF, available from Mikropakk, valves with a leaf spring can be found in the US 6058960, WO 03/062092 and WO 2009/004097.
    Just like conventional valves, these "feststof" valves usually also have a valve cup and a stem. The valve cup of such valves can still be sensitive to deformation under the internal pressure inside the container. These valves are usually provided with at least one seal section on the outside of the valve stem, suitable for forming a seal, when brought into contact with a gun adapter, a dosing gun, or a manual applicator. These sealing sections may consist of slats for improving the sealing action, and these slats may be provided at suitable locations on the outside of the valve. Examples of such slats are described in US 5014887, US 6058960 and in WO 2009/004097.
    In one embodiment of the hand-operated applicator from the assembly of the present invention, the applicator is suitable for use with all types of gun valves. Thus, these types may also include the conventional gun valve that includes the rubber seal, the gun valve that includes the external seal, the gun valve that includes an internal coil spring, the gun valve that includes an external coil spring, and the gun valve that includes a leaf spring. The manual applicator can therefore be provided with a number of sealing sections, optionally additionally provided with blades. These sealing sections may be provided on the various internal surfaces that may contact external surfaces of one of the valves, such as, for example, on the inside of the strictly cylindrical portion of the receiving device, or on conical sections provided as part of the receiving device, or on the bottom of the hollow cylinder or of a receiving device with a different shape. We prefer at least one sealing section on the inside of the strictly cylindrical portion of the receiving device, but we also prefer a sealing section on at least one of the other internal surfaces mentioned, and most preferably on all of the said surfaces .
    Applicants have found that the manual applicator from the assembly of the present invention can also be made suitable for operation with a straw valve container. The applicator can be provided to also engage the stem of a straw valve in such a way that the movement of the movable part of the applicator results in pushing down the stem of the straw valve into the contents of the straw valve. container, preferably by a movement along the axis of symmetry of the stem of the valve.
    In one embodiment of the applicator from the assembly according to the present invention, the intervention of the hand on the applicator is a pinching motion. Pinching is by far the most natural and the easiest action that can be performed with one hand, and offers the best control of the force exerted by the hand on the applicator. This provides further improved ergonomics, targeting and dosing options for the user.
    In an embodiment of the applicator from the assembly according to the present invention, the lever surface provides a trigger in cooperation with the grip surface, preferably in addition to the gun handle, if present. This entails the advantage that the use of the manual applicator is closer to the use of the more ingenious dosing device or dosing gun, with all the associated advantages in terms of ergonomics, aiming and dosing capacities.
    In an embodiment of the applicator from the assembly according to the present invention, the fixed portion further comprises a grip surface for contact with at least one finger, preferably for the index finger, more preferably for closing the hand around the applicator in cooperation with the thumb of the hand. This brings the resemblance to the use of a dosing gun even closer.
    In an embodiment of the applicator from the assembly according to the present invention, the total grip surface on the fixed part for contact with the palm of the hand has an area of at least 10 cm 2, preferably at least 20 cm 2, more preferably at least 30 cm 2, even more preferably at least 40 cm 2 and most preferably at least 45 cm 2, typically about 50 cm 2, and / or the lever surface on the movable member has an area of at least 4 cm 2, preferably at least 5 cm 2, more preferably at least 6 cm 2, even more preferably in the range of 7-9 cm 2 and typically 9 cm 2, preferably the grip surface for contact with the palm of the hand and / or the lever surface, more preferably at least the grip surface for contact with the palm of the hand, provided as a surface with at least partially a rough texture.
    In an embodiment of the present invention, the applicator is further provided with a transport tube for discharging the contents of the container, preferably this transport tube is provided with a connection for collecting a hose or hose, to allow the contents discharge the container from the container in a targeted manner, wherein preferably the transport tube and / or the hose or hose, when connected to the connection, is provided for passing between two fingers of the hand, preferably between the index finger and the middle finger when the hand grips around the applicator, preferably around the pistol grip if present, to act upon it. Applicants have found that this entails the advantage that the compound can be applied with a higher precision, allowing for a further reduction of the amount of excess compound that is usually applied and which must later be removed and ends up as waste. This means a further reduction in the amount of aftercare work required and entails even greater efficiency in material consumption.
    In an embodiment of the applicator from the assembly according to the present invention, the movable member is connected to the fixed member by means of a resilient member adapted to allow, due to its reversible deformation, to pivot the movable member relative to the fixed part, wherein the pivoting preferably runs around a virtual axis of rotation, and more preferably, that virtual axis of rotation lies approximately in an imaginary plane which runs through the point of engagement between the movable part and the lid of the container, perpendicular to the direction of movement of the valve stem, and the resilient member is preferably provided as an integral part of the applicator. Applicants have found that this location of the resilient member relative to the stem of the valve has the advantage that it acts on the applicator, causing the movable member to pivot or rotate at least a small angle with respect to the fixed member , translates into a substantially linear movement of the stem of the valve straight into the container, and this with a minimum of friction between the applicator and the stem of the valve. This entails the advantage of minimizing the force that must be exerted on the applicator to reach a certain opening of the valve, which further improves ergonomics, as well as the targeting and dosing options. We have found that that resilient member can be provided as an integrated part of the applicator, such as by a portion that is suitably designed to bend and that, when produced from a material with a certain resilience, such as a plastic, can act as bending through a resilient member, thereby providing a virtual axis of rotation.
    In an embodiment of the applicator from the assembly according to the present invention, the fixed part is provided with a first cylindrical part which comprises a protruding edge for clicking or sliding over the applicator on the valve flange of the container, as described above is the flange connecting the plate of the valve and the head of the container, and / or a second cylindrical portion that includes a protruding edge to snap or slide the applicator onto the head flange of the container, preferably on and / or over both, and thereby attach the applicator to the container. Applicants have found that by having a substantially full circular contact of the applicator with the container where it is clicked on one of the flanges, it offers the advantage of an improved attachment of the applicator to the container, stronger in comparison with a only partial contact and completely reliable in terms of recording the relative positions of the container and the applicator. Applicants prefer to snap the applicator onto the flange of the container valve, because this flange is the smaller flange, and this connection can therefore be most easily achieved with a minimum of building material for the applicator, and proved to be sufficient for the purpose. . Nevertheless, the applicator can alternatively or additionally be clicked on the head flange of the container to achieve and / or improve the connection of the two elements of the assembly.
    In one embodiment of the present invention, the applicator further comprises a hollow cylinder as a receiving device for engaging the container valve, a conveying tube for discharging the contents of the container movably arranged on the receiving device, the conveying tube being provided to the action to be engaged on the stem of the valve and whereby the seal of the valve, if any, is compressed in the direction of the engaging action on the stem and extends perpendicularly to this direction and thereby against the hollow cylinder of the valve the applicator is pressed, thereby reinforcing or tightening the seal, which may preferably already exist between the valve and the applicator receiving device, and which seal is preferably further improved by slats provided on the outside of the valve and / or on the inside of the hollow cylinder, more preferably on both sides. Applicants have found that this engagement between the hollow cylinder of the applicator and the outside of the gun valve provides a seal that protects the compound leaving the container from contact with the environment on one side and the compound on the other side. leaves the container impossible to inadvertently escape or leak sideways instead of flowing through the transport tube intended to guide the flow of the compound. Each slat provided as part of this seal provides a further improvement of the sealing action of the sealing sections.
    In an embodiment of the applicator from the assembly according to the present invention, the receiving device is flexibly connected to the transport tube such that, due to the action on the applicator, the transport tube is displaced vertically with respect to the receiving device, preferably the flexible connection is made with a shoulder on the transport tube and / or the flexible connection is realized by means of a membrane, whereby the movement of the transport tube in the direction of the valve is facilitated and one end of the hollow cylinder is closed, with most the flexible connection and / or the membrane are preferably provided as an integral part of the applicator. Applicants have found that, especially when the membrane is made of a material impervious to liquids and gases such as air, this offers the advantage of a further seal of the compound leaving the container from contact with the environment, and prevents furthermore unintended leakage of the compound.

Applicants have found that such plastics provide sufficient strength, together with sufficient resilience, to be able to provide all essential and desirable parts of the applicator as integral or integrated parts, and that due to a suitable mold design, the applicator can be produced as a single product in a single step of injection molding. Applicants have found that with these building materials, by adjusting the design and material thicknesses of the various parts, those parts of the hand-operated applicator that must be flexible and / or resilient can be formed as flexible and / or resilient parts, and which parts that must be rigid can be formed as rigid parts.
    In the assembly of the present invention, the container is a gun valve container, and more preferably, the container valve is then a so-called "feststof valve", ie. a valve which in contact with the contents of the reservoir comprises only materials that have little to no permeability to water and / or propellant gases, such as rigid plastic and / or metal, but no rubber parts, in particular no parts of rubber powder supplemented with carbon powder and wherein the assembly preferably provides a seal between the valve and the applicator receiving device, and which is preferably further improved by lamellae provided on the outside of the valve and / or on the inside of the hollow cylinder, more preferably on both sides. These "feststof" valves can also be characterized in that the materials of the valve parts that come into contact with the contents of the reservoir are virtually impermeable to water and / or propellant gases. The valves can for instance be provided with at least one metal spring, and can therefore be opened more easily and closed more quickly, and among other things offer even more improved ergonomics for the user and improved targeting and dosing possibilities.The other advantages have already been discussed above.Another advantage is that these valves are less sensitive to distortion by the internal pressure in the container, especially when the container is sealed and the internal pressure and temperature builds up, for example as a result of chemical reactions in the container, which means that there is less risk of the stem of the valve being moved from its original position, which reduces the risk that the stem of the valve is no longer in the optimum position i s, suitable for the manual control applicator of the present invention.
    In another embodiment, the assembly according to the present invention further comprises a hose or hose which is preferably connectable or connected to the connection, if present, and which is suitable for allowing the efficient discharge of the contents of the container, wherein the trunk or hose is preferably clicked into a clamp, which is provided as part of the applicator and / or container, possibly the trunk or hose is made of a resilient material and is bent or folded in the clicked position, at preferably such that by releasing the trunk or hose from the clamp, the trunk or hose extends into its un-bent or extended position, which is preferably the position of the trunk or hose that is ready for use. This trunk forms a further supplement to the assembly with the elements that the user expects to be required for the application of the compound in the container. The preferred embodiments are very useful for storage and transport of the assembly from the place of production through the distribution chain to the consumer.
    In an embodiment of the assembly according to the present invention, the assembly further comprises an accessory item, which is preferably provided in a cavity for providing an accessory item, if present. Such an accessory article can for instance be at least one and preferably a pair of gloves suitable for protecting human skin against contact with the contents of the container.

    In another embodiment of the method according to the present invention, the mold further comprises one or two casting cores for forming at least one opening that is internal to the hand-operated applicator, such as a transport tube or a hollow cylinder. This method allows the applicator to be produced as a single product with all essential and desired elements as integral parts thereof, and in a single production step.
    The method of the present invention further comprises the step of assembling the applicator with a container. We prefer to provide means for ensuring that the applicator does not tilt with respect to the container, or means for ensuring alignment of the applicator with respect to the container. This can be achieved, for example, by specific conductors or by inserting a "conductive head" into the applicator during the mounting step, such that the alignment remains guaranteed and tilting is avoided.
    In another embodiment of the method according to the present invention, the applicator is picked up by means of a vacuum applied by a suction cup provided on the external flat surface on the applicator, preferably on top of the closure covering the cavity for the accessory object, and the applicator is released by breaking the vacuum after the applicator is brought into a position on the container suitable for clicking the applicator on the container.
