Summary of the Invention

[0010] The purpose of this invention is to enable the flexible use of conventional valves and / or the simple and cost-effective production of valve arrangement structures and / or distribution equipment.

[0011] The above objectives are achieved by the valve arrangement structure, distribution device, or method according to embodiments of the present invention.

[0012] In particular, this invention provides a remarkably simple possibility for the selective application and / or use of valves known per se and / or conventional valves with different valve plates, which can be selectively constructed of plastic or metal without requiring the valve itself to be adaptable. This enables simple and cost-effective production and / or assembly. Furthermore, it increases flexibility in the production of valve arrangement structures and / or distribution equipment, as different parts, especially valve plates, can be used with the same standard valves.

[0013] The proposed valve arrangement is designed for distributing fluid, particularly from a container. The valve arrangement includes a valve plate for securing it to the associated container. Furthermore, the valve arrangement includes a valve body and a fixing part for securing the valve body to the valve plate. Preferably, the fixing part is a separate component from the valve body. This allows the use of standard valves with different valve plates.

[0014] Preferably, the fixing parts are friction-welded and / or radially welded to the valve plate, wherein both are preferably made of plastic. This facilitates flexible application, cost-effective production, and a robust and / or reliable fixation of the valve body to the valve plate.

[0015] The fixing part is preferably ring-shaped or cap-shaped. This facilitates simple and cost-effective production and / or assembly.

[0016] The retaining component preferably has a coupling portion for rotationally fixing the retaining component to the head during assembly. Specifically, the coupling portion is designed so that the retaining component can be held by the head for friction welding and / or during friction welding. This achieves simple and / or secure coupling between the retaining component and the head for friction welding and / or during friction welding.

[0017] Preferably, the coupling portion is arranged or formed on the columnar, particularly hollow, columnar portion of the fixing part. This achieves simple and / or robust coupling between the fixing part and the head for friction welding and / or during friction welding.

[0018] The coupling portion is preferably arranged or formed on the end face and / or axial end of the fixing part and / or columnar portion. This facilitates a simple and secure coupling between the fixing part and the head during assembly.

[0019] The coupling portion is preferably formed by or has one or more axially extending recesses or protrusions. This allows for a simple and secure coupling of the fixing part to the head.

[0020] The fixed part preferably has a welding area, which is designed to melt and / or plasticize during friction welding to form an adhesive connection and / or welded joint with the valve plate. This allows for the creation of a particularly strong and / or robust connection in a simple manner.

[0021] The welded area and / or welded joint is preferably circumferential and / or annular. In particular, the welded area and / or welded joint has an extension of at least 3 mm, preferably about 5 mm or more, in the axial direction. This facilitates a strong and / or pressure-resistant fixation.

[0022] The fixed parts can be selectively arranged on the inside or outside of the valve plate.

[0023] Preferably, the valve plate, fixing parts, valve body, valve elements, and / or the springs and / or valve arrangement structure of the valve arrangement are integrally made of plastic, particularly PET. This enables cost-effective production.

[0024] Preferably, the valve body can be form-fitted to the valve element, seal, and optionally a reset element to form a valve. Specifically, the valve body, valve element, seal, and optionally reset element are connectable and / or linked together such that they remain connected and / or do not fall apart during normal use and / or in the absence of external influences, allowing the valve to be inserted into and connected to the valve plate as a whole and / or as a pre-assembled component. This, in particular, facilitates assembly.

[0025] According to another aspect, which can also be implemented independently, in the proposed valve arrangement, the fixing parts are laser-welded or ultrasonically welded to the valve plate. In particular, this is provided as an alternative to friction welding of the fixing parts to the valve plate.

[0026] Specifically, the fixing part has a first columnar or conical portion and a second portion that protrudes radially from the first columnar or conical portion. This allows for the formation of a contact surface between the valve plate and the fixing part that is easily accessible to the laser beam.

[0027] The fixed part preferably has a welding area. The welding area is specifically arranged on the second part. Preferably, the welding area has a triangular or rectangular cross-section.

[0028] Particularly preferred is that the valve plate is made of a laser-absorbing and / or dark-colored, particularly black, material, and the fixing parts are made of a transparent, particularly laser-transparent, material. This allows for laser welding and / or ultrasonic welding of the fixing parts to the valve plate in a simple manner.

[0029] According to another aspect, which can also be implemented independently, the present invention relates to a dispensing device for dispensing fluid. The dispensing device includes a container and a valve arrangement having a valve plate fixed to the container.

[0030] Preferably, the valve plate is friction-welded and / or radially welded to the container.

[0031] According to one preferred aspect, the valve plate is axially flush with the container.

[0032] Alternatively or additionally, the valve arrangement, particularly the valve plate and / or container, is made of plastic, especially PET. This enables cost-effective production.

[0033] The valve plate preferably has a coupling device designed for anti-rotation coupling of the valve plate to a tool and / or retainer, for friction welding of the valve plate to the container. Preferably, the coupling device is formed or particularly has the following: radially extending coupling elements, especially radially extending coupling elements arranged on the upper side of the valve plate. The coupling elements are particularly preferably arranged in a particularly annular recess in the valve plate. This allows for reliable coupling in a simple manner.

[0034] The container preferably has a coupling portion designed for anti-rotation coupling with a tool and / or retainer during friction welding of the valve plate to the container and / or during friction welding of the valve plate to the container. The coupling portion is particularly arranged in or on the neck region of the container.

[0035] According to a preferred embodiment, the coupling portion has one or more coupling elements that protrude radially from the container. This enables reliable coupling in a simple manner.

[0036] According to another aspect, which can also be implemented independently, the present invention relates to a method for producing a valve arrangement structure for distributing fluid. Preferably, the valve arrangement structure has one or more of the features mentioned above and / or described below. In this method, in particular, the fixing parts are friction-welded and / or radially welded to the valve plate.

[0037] According to a particularly preferred variant, the valve is inserted from the inside of the valve plate into the assigned receiving portion and / or opening of the valve plate, a fixing part slides on the valve and is arranged on the inside of the valve plate, and then the fixing part is welded to the valve plate.

[0038] According to another variation, the valve can also be inserted from the outside of the valve plate into the assigned receiving portion and / or opening of the valve plate, with the fixing part sliding on the valve and arranged on the outside of the valve plate, and then the fixing part is welded to the valve plate.

[0039] According to another aspect, which can also be implemented independently, the present invention relates to a method for producing a valve arrangement structure for distributing fluid, wherein a fixing part is laser-welded or ultrasonically welded to a valve plate. In particular, this is provided as an alternative to the method described above, in which the fixing part is friction-welded to the valve plate.

[0040] Particularly preferably, the valve is first inserted into the assigned receiving portion of the valve plate, and then the fixing part is inserted or placed into the receiving portion, such that the valve is arranged between the valve plate and the fixing part, particularly clamped between the valve plate and the fixing part, with the fixing part resting against the valve plate. Then, preferably, the valve plate is welded together by irradiating the valve plate with a laser beam passing through the fixing part.

[0041] According to another aspect that can also be implemented independently, the present invention relates to a method for production dispensing equipment, wherein a valve plate is friction-welded to a container such that the valve plate is radially welded to the container and / or axially flush with the container.

[0042] The foregoing and subsequent aspects and features of the present invention can be combined with each other in any way, but can also be implemented independently of each other. Attached Figure Description

[0057] In the accompanying drawings, the same reference numerals are used for equivalent or similar parts and devices, wherein the same or corresponding advantages and features can be obtained, even if repeated descriptions are omitted.

[0058] Figure 1 and Figure 2 The dispensing device 1 according to the first embodiment is shown. Figure 2 The dispensing device 1 according to the first embodiment is shown in a fully assembled state.

[0059] The dispensing device 1 has the proposed valve arrangement structure 2 and container 3. The valve arrangement structure 2 is preferably at least partially arranged or positioned in the opening 3A of the container 3. In particular, in the case of the (fully assembled) dispensing device 1, the container 3 or its opening 3A is closed or sealed by the valve arrangement structure 2.

[0060] Valve arrangement structure 2 has valve 4 and valve plate 8.

[0061] Valve 4 has a valve housing 5, a movable valve element 6, and preferably a reset element 7. In an exemplary embodiment, the reset element 7 is preferably designed as a compression spring and / or a helical spring. However, unlike the exemplary embodiment, the reset element 7 may also have any other geometry, by which (elastic) restoring force and / or spring force are achieved or can be achieved. The reset element 7 may be made of plastic or metal.

[0062] Valve element 6 is preferably movable within valve housing 5 and / or axially movable relative to valve housing 5. Preferably, valve element 6 is preloaded to a position by means of reset element 7, in which valve element 6 closes valve 4 and / or valve 4 is closed.

[0063] In this invention, the "axial" direction or movement is understood as a direction or movement extending along or parallel to the main dispensing direction or central axis and / or longitudinal axis L of the dispensing device 1. Similarly, the term "radial" preferably also refers to the axis L.

[0064] In the figure, the cross-section passing through the valve housing 5 to the left of axis L and the cross-section to the right of axis L extend in different planes, that is, between two ribs in the ribs on the outer side of the valve housing. This can be seen in the figure, rather than passing through one of the ribs. As will be explained later, especially in... Figure 2 This makes it easier to see the fluid path when filling the dispensing device 1.

[0065] The valve plate 8 is preferably designed and / or configured to receive and / or retain the valve 4 and / or to secure the valve 4 to the container 3.

[0066] The valve plate 8 preferably has a receiving portion 9 to receive / accommodate the valve 4. The receiving portion 9 preferably has a centrally or centrally arranged opening or hole 9A.

[0067] Preferably, the container 3 or its opening 3A is fluid-tightly and / or airtightly closed and / or sealed by means of the valve plate 8.

[0068] Furthermore, the valve arrangement 2 and / or valve 4 preferably have a seal 10 for sealing the valve 4 against the valve plate 8. The seal 10 is preferably annular and / or disc-shaped.

[0069] The seal 10 is preferably deformable and / or preferably made of a flexible and / or elastically deformable material.

[0070] Preferably, the valve housing 5, valve element 6, seal 10, and optional reset element 7 can be connected and / or linked together, allowing the valve 4 to be pre-assembled. Specifically, the valve 4 pre-assembled in this manner forms a continuous assembly that can be inserted as a whole into the valve plate 8. In other words, the valve housing 5, valve element 6, seal 10, and reset element 7 can preferably be connected and / or pre-assembled so that the valve 4 can be treated as a continuous valve 4 when assembling the valve arrangement structure 2 and / or the dispensing device 1, particularly ensuring that the parts do not separate during assembly. This facilitates handling due to the reduced number of individual parts to be processed during assembly.

[0071] Preferably, the valve arrangement structure 2 has separately manufactured fixing parts 11 for securing the valve 4 and / or the valve housing 5 to the valve plate 8. The fixing parts 11 are preferably capable of being bonded to the valve plate 8 by adhesive bonding.

[0072] Valve housing 5, valve element 6, reset element 7, valve plate 8, seal 10, and fixing part 11 are preferably formed as components that are structurally separate from each other and / or manufactured separately.

[0073] Preferably, the valve plate 8, the fixing part 11, the valve arrangement structure 2, the valve 4, the valve body 5, the valve element 6, the reset element 7 and / or the container 3 are made of plastic, especially PET / polyethylene terephthalate.

[0074] Preferably, the container 3 and / or the dispensing device 1 may be filled with fluid F, particularly after the valve arrangement structure 2 is assembled. Preferably, the dispensing device 1 and / or the container 3 are filled with compressed gas and / or propellant gas G in addition to fluid F, such that fluid F is pressurized in the container 3 and / or the dispensing device 1. Preferably, overpressure exists in the dispensing device 1 caused by the propellant gas G.

[0075] Furthermore, the dispensing device 1 may have other means for dispensing fluid F, not shown in the figures, particularly in the form of nozzles, spray heads, etc. This particularly enables the dispensing of fluid F in a desired form (controlled) as, for example, foam or spray / aerosol, and / or the generation of the desired dispensing form.

[0076] Valve 4 can preferably be opened and closed, particularly by movement of valve element 6 relative to and / or axially toward valve housing 5.

[0077] Preferably, in order to dispense fluid F, the valve element 6 is pressed and / or moved into the valve housing 5 against the force of the reset element 7 and / or the spring, for example by means of a dispensing head or nozzle (not shown), thereby opening the valve 4. In particular, the dispensing head or nozzle is plugged into or connected to the free end of the valve element 6. Then, the pressure of the propellant gas G discharges fluid F from the container 3 through the valve 4.

[0078] Preferably, a supply or rise / up line 12 is provided, which is arranged at and / or connected to the valve 4 and / or valve housing 5, through which fluid F can first rise during distribution so that it can be distributed via the valve 4 in the normal use position when the container 3 is pointing downward.

[0079] During dispensing, fluid F enters the internal space 5B of valve housing 5 from riser line 12. When valve element 6 is pressed downward, preferably the lateral passage and / or radially extending passage 6A of valve element 6 is released, which is sealed by seal 10 when valve 4 is closed. After passing through passage 6A, fluid F emerges at the top of valve element 6. The path of fluid F during dispensing is... Figure 2 The arrow on the right indicates this.

[0080] Valve 4, and in particular valve housing 5, is preferably held and / or fixed to valve plate 8 by means of fixing part 11.

[0081] The valve plate 8 preferably has an inner side and an outer side. The inner side of the valve plate 8 is the side that supplies the interior of the container 3 and / or faces the interior of the container 3 after assembly. Figure 1 and Figure 2 In this configuration, the lower or bottom side of the valve plate 8 is the inner side. The outer side of the valve plate 8 is the side of the valve plate 8 that faces away from the interior of the container 3. Figure 1 and Figure 2 In the middle, the upper or top side of the valve plate 8 is the outer side.

[0082] exist Figure 3 The image shows a fixing part 11 according to the first embodiment.

[0083] The fixing part 11 is preferably designed as an annular and / or at least substantially cylindrical and / or hollow cylindrical or sleeve-shaped.

[0084] Preferably, the fixing part 11 has a coupling portion 13. The coupling portion 13 is preferably designed to couple the fixing part 11 to a head and / or tool (not shown) in a rotation-resistant manner during assembly. The head is preferably designed to complement the fixing part 11 and / or the coupling portion 13.

[0085] The coupling portion 13 is preferably arranged on or formed on the columnar portion or area of ​​the fixing part 11.

[0086] Particularly preferably, the coupling portion 13 is arranged and / or formed on the end face and / or axial end of the fixing part 11 or the columnar portion, particularly as shown in the example. Figure 3 As shown in the image.

[0087] The coupling portion 13 preferably has or is formed by one or more axially extending protrusions or recesses 14.

[0088] exist Figure 3 In the illustrated embodiment, the recess 14 is preferably elongated and / or formed as an axially extending notch or cut.

[0089] The cuts or recesses 14 are preferably evenly distributed circumferentially around the fixing part 11. According to... Figure 3 In one embodiment, the fixing part 11 and / or the coupling portion 13 have six recesses 14. However, other solutions are also possible here.

[0090] In order to assemble the valve arrangement structure 2 according to the first embodiment, the valve 4, having a valve housing 5, a valve element 6, a reset element 7, and a seal 10, is preferably arranged in the assigned receiving portion 9 of the valve plate 8, and is inserted into the receiving portion 9 from the inside or underside of the valve plate 8. Before, simultaneously, or after this, the fixing element 11 preferably slides on the valve 4 and / or the valve housing 5.

[0091] Subsequently, valve 4 and / or valve body 5 and / or fixing part 11 are held and / or fixed to valve plate 8, preferably by means of material bonding, especially by welding, particularly preferably by friction welding, to connect fixing part 11 to valve plate 8.

[0092] Friction welding is performed by pressing two parts to be joined together against each other and rotating them at high speed relative to each other. Due to the high-speed rotation, the parts to be joined heat up due to friction to the point that the parts melt or are melted or plasticized at least at their contact surfaces, thus bonding them together. Preferably, the parts to be welded are of the same type or made of the same or similar materials. However, friction welding can also be used to weld together parts made of different materials, such as metal and plastic parts, if desired.

[0093] Particularly preferably, the fixing part 11 is radially welded to the valve plate 8. Thus, in particular, the weld or welded joint forms a connection that extends radially between the fixing part 11 and the valve plate 8 or a portion of the valve plate 8, or radially extends, and / or radially connects the fixing part 11 and the valve plate 8 to each other.

[0094] The weld or welded joint is preferably annular and / or circumferential relative to the axis L.

[0095] The fixing part 11 preferably has a welding area 15.

[0096] At least in the first embodiment, the welding area 15 is preferably located on the outer side and / or circumferential surface of the fixing part 11 or the columnar portion of the fixing part 11.

[0097] Preferably, the welding area 15 is annular or bead-shaped, and / or the welding area 15 particularly completely surrounds the fixing part 11. Specifically, the welding area 15 is formed like an annular groove, and / or the welding area 15 forms a thickened portion of the fixing part 11. Preferably, the welding area 15 protrudes or extends radially from the fixing part 11. The welding area 15 preferably forms a shoulder, step, or protrusion on the outer side of the fixing part 11.

[0098] The welding area 15 is specifically designed to be melted and / or plasticized during welding or friction welding in order to create an adhesive connection and / or welded connection between the fixed part 11 and the valve plate 8.

[0099] In this invention, "plasticization" is understood to specifically refer to the process by which a material, particularly a plastic or metal, is preferably transformed into a plastically deformable state by heating.

[0100] The welding area 15 is preferably designed to have a particularly large area.

[0101] Specifically, the welding area 15 has an extension E of at least 3 mm, preferably about 5 mm or more, in the axial direction or axially or parallel to the longitudinal axis L.

[0102] Preferably, the welding area 15 is arranged in the center in the axial direction and / or at a distance from the axial end side of the fixing part 11. However, other arrangements are also possible.

[0103] exist Figure 4 The valve plate 8 according to the first embodiment is shown in the figure.

[0104] The valve plate 8 and / or the receiving portion 9 preferably have a receiving space 16 to accommodate / receive the valve 4 and / or the valve body 5. In particular, the receiving space 16 is arranged at the valve plate 8, in the middle and / or centrally and / or symmetrical about the axis L.

[0105] According to Figure 4 In an exemplary embodiment, the receiving space 16 is located inside the valve plate 8. The receiving space 16 is preferably at least substantially columnar.

[0106] The receiving portion 9 is preferably formed by the formation of the receiving space 16 and / or the valve plate 8 and / or the wall defining the receiving space 16. The wall of the valve plate 8 preferably has a columnar, particularly axially extending wall portion 16A and a disk-like wall portion 16B extending laterally or perpendicularly to the longitudinal axis L, the wall portion 16B axially defining or closing the receiving portion 9 and / or the receiving space 16. The wall portions 16A and 16B will also be simply referred to below as portions 16A and 16B. Preferably, the columnar portion 16A laterally defines the receiving portion 9 and / or the receiving space 16, and / or the columnar portion 16A forms the side surface of the receiving space 16 and / or the receiving portion 9.

[0107] The disc-shaped portion 16B of the wall preferably has a central opening or hole 9A for the valve element 6 to the outside or for pushing the valve element 6 in from the outside.

[0108] The opening or orifice 9A of the valve element 6 has a smaller diameter than the receiving space 16, such that part 16B can axially retain the valve 4 and / or valve housing 5 and seal 10 in the receiving part 9 and / or receiving space 16 by means of form adaptation.

[0109] Preferably, the fixing part 11, particularly together with the valve 4 and / or the valve body 5, is arranged in the receiving space 16, particularly radially between the portion 16A of the valve body 5 and the valve plate 8, particularly as in Figure 2 It can be seen in the image.

[0110] The outer diameter of the fixing part 11 and / or the welding area 15 is preferably matched with the (inner) diameter of the receiving space 16, such that the outer diameter of the fixing part 11 and / or the welding area 15 is slightly larger than the associated (inner) diameter of the receiving space 16 and / or the portion 16A, particularly by at least 0.1 mm and / or at most 2 mm, so that the fixing part 11 can be friction welded to the receiving space 16 and / or the portion 16A of the valve plate 8.

[0111] In an exemplary embodiment, the retaining part 11 is preferably not, or not fully, or not until its assembled position can be axially inserted into the receiving space 16 without deformation. Preferably, the welding area 15 extends radially from the retaining part 11 such that, before the initial and / or friction welding process begins, the retaining part 11 can be partially axially inserted into the receiving space 16 and / or can be centered in the receiving space 16 until the shoulder formed by the welding area 15 contacts the portion 16A.

[0112] The “excessive” diameter of the fixing part 11 has the following effect: during the rotation of the fixing part 11 and / or during the friction welding of the fixing part 11 to the valve plate 8, when the fixing part 11 is axially moved into its assembly position, the welding area 15 is melted and / or plasticized by frictional heat, so that the fixing part 11 is deformed at least in the welding area 15 and can be fully inserted into the receiving space 16, and the fixing part 11 is bonded to the valve plate 8.

[0113] The opposite approach is also possible, in which, instead of the fixing part 11, the receiving space 16 or portion 16A specifically has a welding area 15 on the inside. In this case, the foregoing description preferably applies in reverse or similarly.

[0114] Preferably, the valve 4 and / or the valve housing 5 are axially held in the valve plate 8 in a form-fitting manner by means of the fixing part 11 on the one hand and by means of part 16B of the valve plate 8 on the other hand.

[0115] Preferably, the valve body 5 has or forms a widened portion or shoulder 5A, particularly on the outer side. The shoulder 5A preferably protrudes radially from the valve body 5. Preferably, the shoulder 5A is formed by one or more elements or ribs that radially protrude and / or extend from at least a substantially columnar portion of the valve body 5.

[0116] The valve body 5 is preferably axially supported on the fixing part 11 by a shoulder 5A or vice versa. The shoulder 5A preferably forms a stop for fixing the part 11.

[0117] Preferably, when the dispensing device 1 and / or valve arrangement structure 2 are fully assembled, the fixing part 11 is firmly placed against the valve housing 5 and the valve housing 5 is firmly placed against the valve plate 8, such that the valve housing 5 is (at least axially) firmly and / or immovably fixed between the valve plate 8 and the fixing part 11.

[0118] Radially, the valve housing 5 is preferably held firmly and / or immovably and / or form-fittedly in the receiving portion 9 and / or receiving space 16, because the ribs having and / or forming the shoulder 5A are radially resting against the portion 16A or its inner side.

[0119] The valve plate 8 preferably has a coupling device 17. The coupling device 17 is preferably designed to anti-rotately couple the valve plate 8 to the tool and / or retainer 27, such that the valve plate 8 can be held and / or rotated, particularly during friction welding with the tool and / or retainer 27, by form adaptation.

[0123] Particularly preferably, the coupling device 17 is formed or has the following: a radially extending web, ribs, or coupling element 17A. The coupling element 17A is preferably arranged or formed on the outside of the valve plate 8, particularly in the annular space 18.

[0124] exist Figure 4 In the embodiment shown, the coupling element 17A is formed by a wall or wall element extending radially in the annular space 18, preferably wherein the coupling element 17A divides the annular space into a plurality of sectors.

[0125] According to another aspect, which can also be achieved independently, on the dispensing device 1, the valve plate 8 is preferably friction-welded to the container 3.

[0126] Preferably, the valve plate 8 has a collar 19 at its outer edge. However, embodiments without the collar 19 are also possible, which will be discussed later, particularly with reference to Figure 10 and Figure 12 .

[0127] Preferably, the collar 19 is formed with an annular groove that opens at the bottom and / or along the direction of the container 3 for receiving the edge 3C of the container 3.

[0128] Preferably, the valve plate 8 is friction-welded to the wall that forms or defines the opening 3A of the container 3 in the region of the collar 19. Preferably, the collar 19 surrounds the wall that forms the opening 3A.

[0129] A seal or sealing ring may also be provided, which is preferably arranged in the collar 19 before the valve plate 8 is welded to the container 3, in particular to ensure a tight seal of the container 3.

[0130] The container 3 preferably has a coupling portion 20. The coupling portion 20 is particularly arranged in the neck region 3B surrounding and / or forming the opening 3A of the container 3.

[0131] The coupling portion 20 is preferably designed for anti-rotation coupling of the container 3 with the tool and / or retainer 28 during friction welding of the valve plate 8 and the container 3. This is particularly important in... Figure 11 and Figure 12 As shown in the image.

[0132] Preferably, the coupling portion 20 is formed by or has one or more coupling elements 20A that protrude radially from the container 3 and / or the neck region 3B. The coupling elements 20A may be evenly distributed on the neck region 3B and / or the container 3. Alternatively, the coupling portion may have only one annular coupling element 20A surrounding the container 3 and / or the opening 3A.

[0133] In the neck region 3B, the walls of container 3 are preferably thicker and / or reinforced.

[0134] Preferably, a step and / or protrusion are formed in the neck region 3B of the container 3 and / or in the collar 19 of the valve plate 8, which allows the valve plate 8 to be easily centered and / or positioned or initially guided in the opening 3A before friction welding.

[0135] The weld or welded joint formed between the container 3 / neck region 3B and the valve plate 8 during friction welding preferably has an axial extension of at least 3 mm, particularly 5 mm or more. This ensures a secure fixation of the valve plate 8 to the container 3.

[0136] The propellant gas is preferably introduced under high pressure into a (fully assembled and preferably already filled with fluid F) dispensing device 1, in which a fixing part 11 is rigidly connected to a valve plate 8 and the valve plate 8 is rigidly connected to a container 3. Due to the high pressure, the propellant gas G deforms the seal 10, creating a gap between the seal 10 and part 16B. The propellant gas G can then first pass between the valve element 6 and part 16B, and then through the gap between the seal 10 and part 16B. The propellant gas G then passes through a channel 5C formed between the rib forming the shoulder 5A in the valve housing 5 and part 16A, through the valve housing 5 and the fixing part 11, and enters the interior of the container 3. The path of the propellant gas G during filling the dispensing device 1 is determined by... Figure 2 The arrow on the upper left indicates this.

[0137] The second embodiment of the distribution device 1 and / or valve arrangement structure 2 will be described in particular below.

[0138] Figure 5 and Figure 6 The dispensing device 1 according to the second embodiment is shown. Figure 7 and Figure 8 The image shows the fixing part 11 and the valve plate 8 according to the second embodiment.

[0139] Preferably, the following will only address the differences between the second and first embodiments, such that unless otherwise explicitly stated, the preceding descriptions and features are particularly applicable to the second embodiment, even if repeated descriptions are omitted.

[0140] Preferably, the second embodiment differs from the first embodiment in that the fixing part 11 and the valve plate 8 are designed differently.

[0141] The fixing part 11 is preferably designed as a cap. In particular, the hollow cylindrical, sleeve-shaped and / or annular portion of the fixing part 11 is adjacent to the end wall 21 at the end side, which extends transversely to and particularly perpendicular to the axis L.

[0142] The end wall 21 preferably has a hole 22 for valve 4 and / or valve element 6, which is preferably arranged in the center or middle.

[0143] exist Figure 7 In the illustrated embodiment, the coupling portion 13 has a recess 14 or is formed by a recess that takes the form of an elongated and / or axially extending radial indentation in the outer edge of the fixing part 11 or its columnar portion. However, other options, such as radial protrusions, are also conceivable here.

[0144] The recesses 14 or indentations are preferably arranged symmetrically on the fixing part 11. According to... Figure 7 In the exemplary embodiment, the fixing part 11 and / or the coupling portion 13 have six recesses 14. However, other solutions are also possible here.

[0145] In the second embodiment, the fixing part 11 is preferably arranged on the outside of the valve plate 8.

[0146] In order to assemble the valve arrangement structure 2 according to the second embodiment, the valve 4, which has a valve housing 5, a valve element 6, a reset element 7, and a seal 10, is preferably arranged in the assigned receiving portion 9 of the valve plate 8, and is inserted into the receiving portion from the outside or top side of the valve plate 8. Before, simultaneously, or after this, the fixing part 11 preferably slides on the valve 4 and / or the valve housing 5.

[0147] Subsequently, valve 4 and / or valve body 5 are preferably held and / or fixed to valve plate 8. The holding and / or fixing of valve 4 and / or valve body 5 to valve plate 8 is preferably carried out by bonding, particularly by welding, to connect fixing part 11 to valve plate 8.

[0148] Particularly preferably, the fixing part 11 is friction-welded to the valve plate 8.

[0149] The difference between the valve plate 8 according to the second embodiment and the valve plate 8 according to the first embodiment preferably (mainly) lies in the design and / or construction of the receiving part 9 and / or the receiving space 16.

[0150] Preferably, the receiving portion 9 and / or the receiving space 16 are at least substantially columnar. However, compared to the first embodiment, the receiving space 16 and / or the receiving portion 9 are preferably not defined on one side by the (wall) portion 16B of the valve plate 8 extending transversely to the longitudinal axis L. In the second embodiment, the function of portion 16B is preferably handled by the cover 21 of the fixing part 11.

[0151] Preferably, a support surface 23 and / or a protrusion are formed or arranged in the receiving portion 9 and / or the receiving space 16. Due to the support surface 23, the diameter of the receiving space 16 preferably decreases in the region of the support surface 23.

[0152] The support surface 23 may be formed by a plurality of individual elements arranged in the receiving space 16. Preferably, the support surface 23 is designed as a one-piece circumferential ring and / or an axial stop for the shoulder 5A of the valve housing 5.

[0153] The support surface 23 is preferably designed to axially hold the valve 4 and / or valve housing 5 in the receiving portion 9 and / or receiving space 16 in a form-fitting manner and / or prevent the valve 4 and / or valve housing 5 from sliding through the receiving portion 9 and / or receiving space 16.

[0154] The support surface 23 is preferably designed to rest against and / or be assigned to the shoulder 5A of the valve housing 5. The support surface 23 preferably forms a stop.

[0155] In the second embodiment, the support surface 23 preferably at least partially takes over the function of the fixing part 11 in the first embodiment, which fits into holding the valve housing 5 in the receiving part 9 and / or receiving space 16 by supporting it on the shoulder 5A of the valve housing 5.

[0156] In the second embodiment, the fixing part 11 preferably has a welding area 15 on the inner side and / or inner edge of the columnar portion. The welding area 15 preferably protrudes radially inward from the fixing part 11 or the columnar portion. Preferably, the welding area 15 on the fixing part 11 according to the second embodiment is not arranged and / or formed at the fixing part 11 with any axial offset or displacement about the coupling portion 13.

[0157] In the case of the fixing part 11 according to the second embodiment, the welding area 15 is preferably arranged on the inner side or inner surface of the fixing part 11 or on the inner side or inner surface of the columnar portion of the fixing part 11.

[0158] The inner side of the fixing part 11 is preferably welded to the wall portion 16A, which forms the inner boundary and / or inner wall of the annular space 18.

[0159] The inner diameter of the fixing part 11 and / or the welding area 15 preferably matches the outer diameter of the portion 16A, such that the inner diameter of the fixing part 11 and / or the welding area 15 is slightly smaller than the outer diameter of the portion 16A, particularly by at least 0.1 mm and / or at most 2 mm, allowing the fixing part 11 to be friction-welded to the portion 16A. Therefore, the fixing part 11 preferably does not slide on the portion 16A and / or the receiving space 16 without deformation. The “too small” diameter of the fixing part 11 has a particular effect that during rotation of the fixing part 11 and / or during friction welding of the fixing part 11 with the valve plate 8, the welding area 15 is melted and / or plasticized by frictional heat, making the fixing part 11 deformable at least in the welding area 15 and able to slide on the receiving space 16, with the fixing part 11 bonded to the valve plate 8 or the wall portion 16A of the valve plate.

[0160] In the second embodiment, the opposite arrangement is also possible, in which the welding area 15 is arranged on the outside of the portion 16A instead of on the inside of the fixing part 11.

[0161] In the following text, based on Figure 9A , Figure 9B , Figure 10 , Figure 11 and Figure 12 The third and fourth embodiments of the present invention will be described in detail. In particular, the differences from the first and second embodiments will be mainly explained. Unless otherwise explained, the above explanations preferably also apply to the third and fourth embodiments described below.

[0162] Compared to the embodiments described so far, it is preferable that in the third and fourth embodiments, the fixing part 11 is laser-welded or ultrasonically welded to the valve plate 8 instead of friction welding.

[0163] The fixing part 11 according to the third and / or fourth embodiments preferably has a first segment / part 24 and a second segment / part 25.

[0164] The first part 24 is preferably columnar or hollow columnar. However, the first part 24 may also be slightly conical. In this way, a clamping effect can be achieved when the fixing part 11 or the first part 24 is inserted into the receiving space 16 of the valve plate 8.

[0165] The second part 25 preferably protrudes radially from the first part 24 and / or is arranged at least substantially perpendicular to the first part 24.

[0166] The second part 25 is preferably arranged at the axial end of the fixed part 11.

[0167] The second part 25 is preferably flange-shaped or ring-shaped.

[0168] Preferably, the second portion 25 is designed to contact the lower surface and / or the radially extending defining surface of the annular space 18 of the valve plate 8.

[0169] The fixing part 11, particularly the second part 25, preferably has a welding area 15. In particular, the welding area 15 is annular and / or arranged coaxially with the first part 24. However, in principle, the welding area 15 can be formed by multiple discontinuous protrusions, particularly small-area and / or dotted protrusions, so that a continuous weld 26 is not formed during welding, but only a spotted weld joint is formed.

[0170] according to Figure 9A In the embodiment shown, the welding area 15 (in cross-section) is rectangular. However, the welding area 15 can also have a triangular cross-section, particularly as in... Figure 9B As shown in the figure. However, in principle, other shapes of the cross-section of the welded area 15 are also possible, such as circular, especially semi-circular or other cross-sections.

[0171] The welding area 15 is specifically designed to be plasticized during laser welding and / or ultrasonic welding, thus forming a weld 26 between the retaining part 11 and the valve plate 8. Specifically, it is possible that the retaining part 11 welded to the valve plate 8 does not abut against the valve plate 8 with its entire surface, but preferably only in the area of ​​the weld 26. This compensates for unevenness and / or tolerances of the valve plate 8 and / or the retaining part 11. In particular, this reliably ensures that the seal 10 is securely clamped in place and / or the valve body 5 is positioned without clearance within the valve plate 8 and / or the valve body is clamped without clearance between the valve plate 8 and the retaining part 11.

[0172] The welding area 15 preferably forms a raised portion and / or excess material of the second portion 25. The (axial) thickness and / or height of the welding area 15 is preferably more than 0.2 mm and / or less than 1.2 mm, particularly about 0.8 mm. Preferably, this allows for axial tolerance and / or compensation for unevenness of the valve plate 8 and / or the fixing part 11.

[0173] In order to produce and / or connect the valve arrangement structure 2, it is preferable to first insert the valve 4 into the receiving part 9 and / or the receiving space 16, particularly from the inside of the valve plate 8. Then, preferably, the fixing part 11 is also inserted into the receiving part 9 and / or the receiving space 16, such that the valve 4 is arranged between the valve plate 8 and the fixing part 11, particularly clamped between the valve plate and the fixing part.

[0174] Valve plate 8, valve 4 / valve housing 5 and fixing part 11 are preferably sized and / or matched relative to each other, such that when fixing part 11 is fully inserted into receiving part 9 and / or receiving space 16 and / or valve 4 is clamped between valve plate 8 and fixing part 11, second part 25 and / or welding area 15 rest against the underside of valve plate 8, in particular utilizing its surface.

[0175] Preferably, the valve plate 8 is made of a laser-absorbing and / or dark, particularly black, material, and the fixing part 11 or at least the second part 25 is made of a transparent, particularly laser-transparent, material, so that the valve plate 8 can be irradiated with a laser beam through the fixing part 11 to create a welded connection with the fixing part 11. Therefore, the laser beam can preferably pass through the fixing part 11 without being absorbed.

[0176] To connect / weld the valve plate 8 to the fixed part 11, laser transmission welding or ultrasonic welding is preferably used.

[0177] Preferably, a laser beam is used to irradiate the valve plate 8 and / or the inner side of the valve plate through the fixing part 11. If the valve plate 8 is made of a laser-absorbing material, the material is thus heated. Preferably, the laser beam passes through the welding area 15 and / or the laser beam is directed onto the welding area 15. Due to absorption in the valve plate 8, the material of the valve plate 8 is heated and thus melts and / or plasticizes. This occurs particularly at the immediate adjoining and / or contact surface with the welding area 15. The heat conduction process preferably also causes the welding area 15 to heat and thus melt and / or plasticize, resulting in a weld 26 between the valve plate 8 and the fixing part 11, and the valve plate 8 and the fixing part 11 are bonded together by material bonding.

[0178] For laser welding and / or ultrasonic welding, the valve plate 8 and the fixing part 11 are preferably made of plastic, particularly PET.

[0179] High-power diode lasers, preferably high-power diode lasers with wavelengths greater than 900 nm and / or less than 1100 nm, or solid-state lasers, particularly fiber lasers or Nd:YAG lasers, preferably solid-state lasers with wavelengths greater than 1060 nm and / or less than 1090 nm, are preferably used for laser welding.

[0180] Particularly preferred is that the valve plate 8 is laser-welded or ultrasonically welded to the fixed part 11, and the valve arrangement structure 2 is friction-welded to the container 3, as described above.

[0181] The valve plate 8 may also be collarless and / or lack a collar 19 for the edge 3C of the container 3. This is particularly true in... Figure 10 and Figure 12As shown in the figure. In this case, the valve plate 8 is preferably flush with the container 3 or with the edge 3C of the container (axially).

[0182] In order to connect the container 3 to the valve plate 8 and / or the (pre-assembled) valve arrangement structure 2, especially by friction welding, the valve plate 8 and / or the valve arrangement structure 2 are first inserted into the container 3.

[0183] The valve plate 8 can be inserted in a defined position / rotational position relative to the container 3.

[0184] When the valve arrangement 2 is connected to the container 3, the valve arrangement 2 is preferably held by a first retainer and / or tool 27, and the container 3 is preferably held by a second retainer and / or tool 28. This is illustrated in... Figure 11 and Figure 12 As shown in the image.

[0185] according to Figure 11 In the illustrated embodiment, the coupling element 20A is designed as a collar surrounding the container 3 and / or the opening 3A and / or as a radially projecting element. Preferably, the coupling element 20A has one or more engagement elements, particularly opposite to each other, designed for engagement with the retainer 28. In the exemplary embodiment, the engagement elements are formed by recesses.

[0186] For friction welding, the container 3 and the valve arrangement structure 2 are moved axially toward each other and simultaneously rotated relative to each other about axis L. Specifically, one part, preferably the container 3, is kept in a fixed position, while the other part, preferably the valve arrangement structure 2, is rotated relative to the container about axis L.

[0187] The valve plate 8 is preferably held and / or rotated or rotated by means of a tool 27, which is adapted to engage in the valve plate 8 and / or the coupling device 17 of the valve plate and / or to hold and / or retain the valve plate 8 at the coupling element 17A.

[0188] During friction welding, the valve plate 8 and the container 3 are preferably moved axially toward each other until the valve plate 8 has reached a defined end position and / or axial position relative to the container 3. For this purpose, the valve plate 8 is preferably designed to be without a collar and / or the valve plate 8 does not have a collar 19.

[0189] Preferably, the valve plate 8 is axially flush with the container 3 or the edge 3C of the container at its end position and / or a defined axial position. However, other arrangements are also possible.

[0190] The flush connection allows for a simple and reliable inspection of the established connection between the container 3 and the valve plate 8 and / or the valve arrangement structure 2, as the flush connection and / or the defined positioning of the valve plate 8 is an indication of a correct or error-free connection. In particular, if, after connection has been made, the (columnless) valve plate 8 is not axially flush with the edge 3C of the container, it indicates an error in the connection and / or welded joint.

[0191] Alternatively or additionally, a limited number of rotations, such as precisely 12 rotations, are performed during the friction welding of the vessel 3 and the valve plate 8. This ensures an effective, rapid, and reproducible connection / welding between the valve arrangement structure 2 and the vessel 3.

[0192] During friction welding of the container 3 and the valve plate 8, a welding area 29, particularly circumferential and / or radial, is preferably created. The welding area is specifically the area where, during friction welding, the materials of the container 3 and / or the valve plate 8 are plasticized, thereby forming an adhesive connection and / or weld.

[0193] The width of the welded area 29 and / or the radial extension of the welded area 29 is preferably more than 0.1 mm and / or less than 0.5 mm, particularly about 0.3 mm. The length of the weld 29 and / or the axial extension of the weld 29 is preferably more than 0.5 mm, particularly more than 1 mm and / or less than 2 mm, particularly less than 1.5 mm.

[0194] In operation, the dispensing device 1 preferably has a dispensing head for dispensing fluid F, which is not shown in the figure.

[0195] exist Figure 10 and Figure 12 In the illustrated embodiment, the edge 3C is preferably thickened and / or annular and / or flange-shaped. The edge 3C extends radially from the neck region 3B in particular.

[0196] This allows the dispensing head to be positioned directly at the edge 3C of the container 3, for example, by means of a snap-fit ​​connection with the edge 3C.

[0197] Preferably, the dispensing head is connected and / or attached to the edge 3C via a form adapter. Alternatively or additionally, the dispensing head may be supported on the edge 3C and / or the valve plate 8, particularly when the valve plate 8 is flush with the edge 3C.

[0198] According to another embodiment not shown in the accompanying drawings, the coupling element 20A may be omitted or formed by a (thickened) edge 3C. In this case, it is not necessary to provide the coupling element 20A except for the edge 3C. The edge 3C then preferably has the features described above for the coupling element 20A.

[0199] Various aspects and features of different implementation methods can be implemented and are advantageous individually and in any combination.
