    [0001] [001] The invention reveals an aerosol container, on the opening of the container a valve plate with a spray valve is firmly mounted, the valve disk being made of plastic and has a face of the disk with a piston hole for an element of spray valve valve.
    [0002] [002] An aerosol container with the characteristics described is known from DE 3807156 A1. The valve disc and the valve body of the spray valve are made of a plastic part. The aerosol container is also made of plastic and is welded with a valve plate.
    [0003] [003] In practice, metal aerosol containers are widely used, especially tinplate or aluminum. The valve disc is constructed as a stamped / folded part of tinplate or an aluminum alloy sheet and joined through a metal foil that seals the aerosol container. The disc face of the valve plates is dome shaped, which forms an intake region for the valve body of the spray valve. The valve body, the valve element with a valve shaft (stem) and a seal are used in the dome and fixed by recess inside the dome. A plug-in connection then forms between the valve body and the valve disc. An aerosol container with a metal valve disc and a spray valve attached to it by recoil is known, for example, in DE 2038580 A and FR 2 925 032 A.
    [0004] [004] Aerosol containers are built, in practice, in divided work processes, where the container, the valve disc and the spray valve are often finished by different companies. The valve seats of the spray valve also have standardized dimensions, in most cases, similar or in part. They usually reveal a disc with a front seal, which fits into the inlet region of the valve disc constructed in the form of a dome.
    [0005] [005] For this context the object of the invention is based on an aerosol container with characteristics described above so that the valve disc, made of plastic, can be equipped with a spray valve built separately. In addition, the valve disc must optionally be connected to a metallic aerosol container or an aerosol container made of plastic. Both the connection of the valve disc with the aerosol container and the construction of the valve disc with a spray valve must be easy to assemble.
    [0006] [006] Object of the invention and solution of this problem is an aerosol container according to claim 1. The valve disk of the aerosol container is made of plastic and has a face of the disk with a piston orifice for a valve element of the spray valve. According to the invention, a stable extension is formed on the face of the disc, which constitutes an inlet region for the valve body of the spray valve. The valve body is attached to the inlet region in a seal and is fixed in the inlet region. From this construction, the valve body is fixed firmly in the inlet region of the extension and sealed with a seal, which is positioned between the valve body and the valve disc. The seal is, for example, a circular seal, which can be pre-assembled on a front surface of the valve body. The seal may alternatively consist of a sealing component, which consists of a part in the valve disc. The extension is necessary for the construction of the spray valve essentially only for tensioning. The extension can then be constructed with a relatively small thickness. The valve body is controlled laterally within the intake region below the face of the disc inside the extension formed and has at least one cross section of the container, which it applies at its perimeter inside the container in the intake region.
    [0007] [007] The fixing of the valve body inside the extension inlet region can be done in different ways. In the following, advantageous constructions are described.
    [0008] [008] The valve body is preferably insertable with a pluggable part in the extension inlet region and connected through at least one separable and manipulable fastening element with the extension. The protection element is a separate part. The connection can be made, for example, by bolts, grub screws or screws, which are attached to the extension cover and acting on the valve body. The protection means can be used, for example, holes, threaded holes or also in a groove in the valve body housing. The mechanical connection can be configured with both disconnectable and non-disconnectable fixings.
    [0009] [009] According to the construction of the invention described above, the extension and the valve body of the spray valve are connected by a bifurcated retention spring, which is self-fitting on the outside of the extension, where the retention spring is attached to the extension window and secured behind an axial counterface of the valve body. The fixing ring allows an axial protection condition of the spray valve and can be made of metal or plastic.
    [0010] [010] The valve body and the extension can also be shaped by their shapes or by key-shaped elements, which can be joined to the valve body and / or the extension. If the cross-section is not built cylindrically, a rotating protection can also be carried out simultaneously by means of an adapter of the inlet region shape, so that the valve body can be fixed with a fixed shaft or that they cannot rotate on the valve disk. In particular, the valve body may have a snap hook, which connects to the opening of the perimeter of the extension. The quick fittings can be constructed as arms, which extend the distance even outside the volume of the valve body parallel to the valve body and connect from outside in the openings associated with the extension.
    [0011] [011] A continuous connection between the valve body and the extension can be made further apart in this way, that the valve body has a tapered peripheral surface and the intake region has a complementary tapered peripheral surface and that the peripheral surfaces are provided with toothed profiles, which are fixed with continuous union in vertical contact of the peripheral surfaces of the intake region and the valve body.
    [0012] [012] Another possibility to make the continuous connection of the part made is that the free end of the extension is heated and molded from the inlet of the valve body. In this case, the free end of the extension has a hot forming profile, which attaches a continuous support ring to the perimeter of the valve body.
    [0013] [013] According to the invention, constructive assembly must also fall, which rests on it, that the internal face of the extension and the external face of the valve body have a continuous joining element, which makes the connection through a rotational movement or through a twisting movement in combination with a rotational movement The outer face of the valve body can, for example, be provided with an external thread and have the corresponding inlet region of the extension inlet. The connection can also be made by a type of bayonet lock, through which it is produced by a translational movement in the connection with a rotational movement.
    [0014] [014] The valve body and the extension can also be glued or fused together. The following constructions are based on the fact that the valve body is glued to the extension or is connected by welding materials with the extension. An advantageous construction provides for the valve body to have a glued connection with a ring-shaped face of the extension or to be connected by means of laser welding. Another advantageous construction is that the valve body has a flange, through which the free end of the extension is embedded from the peripheral side and is connected by means of laser welding. The empty space between the free end of the extension and the edge of the body can also be used for adhesion. In this case, the empty space between the interconnected parts is filled with hardened hot glue. For the operation of the aerosol container, it is known that the valve body mounted in the intake region with a determined sealing force. To ensure this, the valve body advantageously has a tapered peripheral surface, which comes in one on the tapered surface of the inlet region for assembly.
    [0015] [015] The disk face of the valve disk preferably has reinforcement ribs. The quantity, geometry and alignment of the reinforcement ribs are then chosen, so that the disc face obtains a sufficiently stable shape, so that it receives the axial forces, which can be produced by means of internal pressure of the aerosol container and either by an assembly spray valve and an aerosol container content. The reinforcement ribs can be directed particularly in the radial direction in relation to the piston orifice. The valve disc can be economically constructed using a plastic injection mold. It is made, in particular, of fiber-reinforced plastic, although a plastic without fiber reinforcement can also be constructed and used. As plastic comes thermoplastic polymers, particularly polyethylene terephthalate (PTE), polyamide (PA), polyethylene (PE), polypropylene (PP) and polybutylene terephthalate (PBT). By using a multi-component injection molding technique, the valve disc may have formed sealing components, composed of, for example, an elastomer, silicone rubber or rubber.
    [0016] [016] According to a preferred construction of the invention, the face of the disc is curved from the outside. The shape of the disc face according to the invention then allows the valve disc to be constructed with a small amount of material. The valve disk also conveniently has a flange, which is connected to a container opening at the limit of the container surface and is supported on the container wall axially. Through the flange the valve disc is centered inside the opening of the container. The axial support facilitates, among other things, the positioning of the valve disc during the assembly process.
    [0017] [017] The aerosol container can be composed of metal or plastic. In the case of a metal container, it is adequately joined by a sheet in continuous connection with the valve disc. In the case of a valve plate for a connection in continuous connection with the metal container is intended, the valve disk has a suitable rim with at least one radial rib, where the rib is flanged in the coating layer of the container and where it is placed a seal between the rim and the coating layer of the container.
    [0018] [018] In the case of a container made of plastic, there are more possibilities for connecting the valve disc with the container considered. Then the valve disc can be welded or glued with the plastic of the container. Through the hot molding of the valve disc, a continuous connection can be produced with the end of the container. In the following manufacturing possibilities, the valve disc and a container made of plastic by means of hot caulking. For connection of the plastic plate with, preferably, a container made of plastic, a non-removable screw connection or a plug-in connection is suitable by applying a recharging unit of more than one part. Construction methods for connecting the valve disc to a container made of plastic or metal are exemplified in claims 19 to 33 and explained below based on construction examples.
    [0019] [019] The measures according to the invention, which refer on the one hand to the connections between the valve body and the valve disc and refer, on the other hand, to the reinforcement of the end of the valve disc in the aerosol container , can be combined with any other.
    [0020] [020] Shown schematically: Fig. 1 a longitudinal section through the object according to the invention, Fig. 2a to 2c views of a valve plate in perspective for the object shown in Fig. 1, Fig. 3 to 14 other constructions of the objects shown in Fig. 1.
    [0021] [021] In Fig. 1 an aerosol container is shown, a valve plate 2 with a spray valve 3 is firmly mounted on the container opening. The valve disk 2 is made of plastic and has a disk face 4 with a piston orifice 5 for a valve element of the spray valve 3. At the bottom of the valve disc a rigid extension 6 is formed, which has an inlet region for the valve body 8 of the spray valve 3. The valve body 8 built in the inlet region on a seal 10 and is mechanically fixed in the inlet region. The valve body 8 is insertable as a socket in the extension 6 and has a body section 81, which connects in its circumference on the internal surface of the intake region. In an assembly example, the body section 81 and the intake region are built cylindrically. Within the scope of the invention it is also proposed that the intake region as well as the body section 81 presented there conveniently fitted in a different cross section in a cylindrical shape, so the valve body 8 is connected, not only axially, but also in a rotating manner on the valve disc 2. The extension 6 and the valve body 8 are joined by means of at least one separate manual safety element. In an example of assembly, the safety element is made of a bifurcated safety spring 7, which is self-locking on the external side of extension 6. In Fig. 1 in connection with Fig. 2a to 2c, it results that the retaining spring 7 engages in the window 61 of extension 6 and attaches behind an axial counterface 9 of the valve body 8. The retaining spring 7 is constructed, in an example of construction, of plastic element. Which, by the built-in retaining spring 7, is still removable.
    [0022] [022] In all example assemblies, the disc face 4 of the valve disc 2 has reinforcement ribs 12, which are aligned radially in relation to the piston orifice 5. The reinforcement ribs 12 are arranged, as described in Fig 2b and Fig. 2c, at the bottom of the disc face. The reinforcement ribs 12 can also be arranged in the upper part of the disc face 4 or both in the upper part and also in the lower part of the disk face 4. The reinforcement ribs 12 give the valve disc 2 a sufficient stiffness for the admission of the internal pressure of the container and for admission of axial forces, which can appear by mounting the spray valve 3 on the valve disc 2 and the contents of the aerosol container in a charged condition. The valve disc 2 shown in Figs 2a to 2c has a shoulder 13, which is connected to a container opening limiting the inner surface of the container and is supported on the container wall axially. The disc face 4 of the valve disc 2 is curved from the outside. The valve disc 2 is made of fiber-reinforced plastic. Suitable plastics are, for example, polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE), polyamide (PA) and polybutylene terephthalate (PBT), where they can contain 30 to 40% by weight of fiber. Depending on the requirement profile, non-reinforced plastics can also be used. Valve disc 2 is economically constructed by injection molding.
    [0023] [023] The aerosol container 1, hereinafter referred to as the container, can be composed of metal or plastic. The construction example shown in Fig. 3 shows a metal container 1, which is joined with the valve disc by means of a continuous joining sheet shape. The valve disc 2 has a lip 14 with two ribs 15, 15 ', where a rib 15 is flanged in the coating layer of the container 1 and a seal 16 is placed between the lip 14 and the coating layer of the container 1.
    [0024] [024] In an assembly example in Fig. 4, the container 1 is made of plastic and has a nozzle 17, which fits into the circular groove 18 of the valve disc 2 and attaches a seal 19 in the form of a circular groove 18. The seal 19 can be inserted into the circular groove as a separate sealing ring or composed of a sealing component, which is formed by valve plate 2 or can be injected into the circular groove 18 for assembly and maintained chemically, thermally or with special light. The circular groove 18 is bounded by an inner wall of the container located on the rim 20 of the valve disk 2 and an outer flap 21. The outer flap 21 has a hot forming profile, which continuously holds the nozzle 17 of the container 1.
    [0025] [025] In Fig. 5 the aerosol container 1 is also made of plastic. The valve disc 2 has a flange 22, which is joined by hot caulking with a container nozzle 23. Between the flange 22 of the valve disc 2 and the wall of the container 1, a seal 24 is positioned. This seal 24 can be formed by a sealing ring. The seal 24 can also consist particularly of a thermoplastic elastomer, which has been formed, for example, by injection molding of multiple components into the wall plate 2. A design variant is shown in Fig. 5a. The seal 24 is formed here by an annular support surface of the valve disc.
    [0026] [026] Fig. 6a and 6b also show a valve plate 2, which has been joined with the nozzle 23 of the plastic container 1 by means of hot caulking. The seal 24 is made of an elastic sealing component, which is formed on a valve plate 2. The valve disc 2 has both the top and the bottom of the reinforcement ribs 12 on the face of the disc 4. Then in a arrangement is provided with circular reinforcement ribs and radial to the reinforcement ribs precisely at the propeller opening.
    [0027] [027] In an assembly example in Fig. 7, the valve disc 2 is joined by laser welding 25 with the pre-existing plastic container 1. Laser weld 25 joins a flange 13 of valve disc 2, which is connected to a container opening at the limit of the inner surface of the container. Laser weld 25 can be produced by a radial laser weld process, whereby the laser beam is reflected by a mirror, which is focused radially on the upper surface symmetrically rotated to the welded part. Alternatively, the laser welding process could also be employed, whereby the part worked would be rotated along its length. With the aid of a laser welding process, a permanent watertight connection can be made. Additional seals could not be made. The solder connection is carried out in a short operating cycle. The wall of the container 1 must be made by laser, while the valve disk 2 is made of a material that absorbs laser. According to a design variant shown in Fig. 7a, laser welding 25 is positioned on a circular front face.
    [0028] [028] In Fig. 8 and 9, connections glued between valve disc 2 and an aerosol container made of plastic are shown.
    [0029] [029] As shown in Fig. 9, the container has a container rim 29 with at least one pocket 30, through which the pocket 30 can be constructed as a circular slot. The valve disc 2 placed on the rim of the container 29 and has a contact element 31 fitted to the pocket 30. The void of the interconnected parts is filled with a hardened hot glue 28. The production of the glued connection takes place in the same way as described above.
    [0030] [030] Fig. 10 and 11 refer to threaded connections between the valve disc 2 and the aerosol container 1. This is constructed as a blow-molded plastic container and has a container rim 32 with a thread that can be made with internal thread 33 or external thread 34. In an assembly example in Fig. 10, the thread is an internal thread 33. The valve disc 2 is joined by means of a threaded connection with the container flange 32, in that a seal 35 is positioned between the container rim 32 and the valve disc 2. In an assembly example in Fig. 11, the threaded connection comprises a nut 36, which is rotated over the outer thread 34 of the container rim 32 and interlock valve valve 2 with the container rim. A seal 35 is also positioned between the container flange 32 and the valve disk 2. This screw connection shown in Figs. 10 and 11 are permanent. They have suitable locking elements, which block the rotational movement of the parts relative to each other in the direction of the opening.
    [0031] [031] Instead of a screw connection, a continuous connection is also possible using a bayonet lock.
    [0032] [032] Fig. 12a shows a connector 37 under the application of a set of clamping elements 38 for connection of the valve disc 2 with a plastic container. The aerosol container made of plastic 1 has a cylindrical neck 39, into which a flange 40 of the valve body 2 fits. In the valve body 2, an outer fixing ring 41 is tightened, which surrounds the neck 39 and limits a wedge circular in cross section between neck 39 and outer fixing ring 41. The outer fixing ring 41 is tightly joined with valve disc 2, for example, by laser welding. Within the outer fixation ring 41, an inner fixation ring 42 is positioned, which fills the circular wedge. The assembly shown in Fig. 12b must also be complemented by the assembly of a spray valve and can then be pressed onto the neck 39. After reaching the position shown in Fig. 12a, the assembly can no longer be removed from the neck 39, as the inner fixing ring 42 is fastened to the outer clamp 41 with the neck 39. When the inner region of the container 1 has a content under pressure, forces will be exerted on the valve disc 2 as well as on the neck. As a result of these forces, the parties 39, 41, 42 will press against each other.
    [0033] [033] In the circular wedge, a seal 43 is positioned to be deformed by a relative movement of both fixing rings 41, 42 and rests an inner surface of the outer fixation ring 41 and an inner surface of the neck 39. In addition, at least one circular seal 44 is positioned on the rim 40 of the valve disc 2, which rests on the inner surface of the neck 39. The surfaces of the inner fixing ring 41 and the neck 39, facing each other, finally show a profile 45 to secure the surface. The connection is no longer removable in this assembly. Due to the prevailing internal pressure of the contents of the aerosol container in the container, the results of the recharge effects increase between the parts. The valve disc can also be joined by a connector with the aerosol container. In an assembly example of Fig. 13, the valve disk 2 has a snap hook 46, which tightens behind a circular connection 47 of the container on the inside of the container. The connector on the inside of the container is inaccessible from the outside and is not removable. In the valve disc 2, an elastomeric sealing surface 48 is firmly formed. As shown in Fig. 14, the snap hook 46 can also tighten behind a nozzle 47 'on the outside of the container. To guarantee the connection on the outer side of the container, a fixing ring not shown can be used, which prevents the hook from being bent.
