Description

[0001] VALVE FOR FILLING AND SIMULTANEOUS REMOVAL OF TWO MEDIA COMPONENTS

[0002] Technical area

[0003] The present invention relates to a valve for filling a first media component into a first container and a second media component into a second container, which can be arranged, in particular is arranged, inside the first container, and for simultaneously removing the two media components from the two containers. The invention also relates to a filling method for a two-media component removal system that includes the valve according to the invention.

[0004] State of the art

[0005] For example, for polyurethane foams in aerosol cans, a 2K valve system (2K = two-component) is known, which makes it possible to dispense the two components from an aerosol can and mix them outside of it in an adapter.

[0006] This well-known valve was developed at a time when CFCs were the primary propellant used for aerosol products, which meant that the requirements for valve systems regarding gas loss, chemical resistance of valve materials, moisture diffusion to the inside, and non-flammability of the propellants were completely different. Even today, this barely developed valve still requires a HFC as the propellant, as the gas loss is too high with commonly used propellants such as propane, dimethyl ether (DME), or isobutane.

[0007] A further disadvantage of the existing system is the fact that the two dispensing openings are located next to each other on the outside of the valve. This requires special effort during production when it comes to gassing or filling the individual components. As a rule, liquid components are poured directly into the cans, and the cans are then closed and gassed through the valve. Due to the round aerosol can, aerosol filling machines can only ever gass or fill from the center from above, as the position of the can does not remain constant during production. Therefore, it is only possible to automatically fill the aerosol can with propellant via the appropriate valve position with considerable technical effort. Aerosol cans are known from the prior art, for example, from WO 01 / 89956.

[0008] This problem was solved by manually applying a filling adapter to the valve after crimping, which allows for centered gassing of the propellant. However, this adapter must be removed manually after gassing.

[0009] The practical application of the product also requires special attention when attaching the application adapter, ensuring that the two dispensing pins in the adapter are correctly positioned in the valve to avoid malfunctions. To assist (better orientation), an arrow marking is usually applied to the release mechanism, or a locking pin is provided to prevent incorrect insertion.

[0010] Description of the invention

[0011] Therefore, it is an object of the invention to provide an improved valve of the generic type. It is also an object of the invention to provide an improved filling method for two-media component dispensing systems. These objects are achieved by the features of claim 1 and claim 15, respectively.

[0012] The present invention relates to a valve for filling and / or gassing a first media component into a first container and a second media component into a second container, which valve can be arranged, in particular is arranged, inside the first container and is designed for the simultaneous removal of the two media components from the two containers, wherein the valve comprises: (a) a valve housing with a longitudinal axis and having a first connection for connecting the valve to the first container, at least one lateral housing passage, a first valve opening, a second connection for connecting the valve to the second container and a second valve opening, (b) a first closure sleeve which is mounted within the valve housing such that it can be moved back and forth along the longitudinal axis and relative to the valve housing between a closed position in which the first closure sleeve closes the first valve opening,and an open position in which the first closure sleeve completely or partially releases the first valve opening and the lateral housing passage thus gains access to the first valve opening, (c) a second closure sleeve, which is mounted in sections within the first closure sleeve and in sections within the valve housing such that it can be moved back and forth along the longitudinal axis and relative to the first closure sleeve and the valve housing between a closed position in which the second closure sleeve closes the second valve opening, and an open position in which the second closure sleeve completely or partially releases the second valve opening and the second connection thus gains access to the second valve opening, (d) a first spring element which is arranged and designed such that it holds the first closure sleeve in the closed position by a first prestressing force, and (e) a second spring element,which is arranged and designed so that it holds the second closure sleeve in the closed position by a second prestressing force.,

[0013] In some embodiments, the first spring element pushes the first closure sleeve away from the second container. In other words, the first preload force of the first spring element is directed away from the second container, i.e., outward, away from the interior.

[0014] In some embodiments, the second spring element pushes the second closure sleeve away from the second container. In other words, the second preload force of the second spring element is directed away from the second container, i.e., outward, away from the interior.

[0015] In some embodiments, the first closure sleeve and the second closure sleeve are formed separately from each other. In other words, the first closure sleeve and the second closure sleeve are not designed as a single piece. This allows the two containers to be filled and / or emptied independently of each other.

[0016] In particular, the first container encloses the second container and a large part of the valve.

[0017] In particular, the valve housing can be constructed in one or more parts. For example, the second connection can preferably be manufactured as a single part, i.e., with properties specifically designed for connection to the second container, but then rigidly and tightly connected to the rest of the valve housing.

[0018] In particular, the first connection has elements or active areas by means of which a tight, and in particular permanent, connection with the first container can be established. For example, a first metallic collar is provided on the first connection, which is designed to form a positive and / or material-locking connection with a second metallic collar of the first container. The first connection can also have a pressure-resistant shape.

[0019] In particular, the valve housing has a generally cylindrical shape, especially with one or more outer shoulders or steps. The longitudinal axis defines the rotational axis of the generally cylindrical shape. The valve housing is not necessarily rotationally symmetrical. Preferably, the valve housing forms a substantially cylindrical cavity on the inside, provided with shoulders.

[0020] In particular, the at least one lateral housing passage is formed as an opening in the outer shell of a central region of the valve housing. Specifically, this can be a bore or a radially evenly distributed number of bores in the shell of the valve housing.

[0021] In particular, the first valve opening is arranged inside the valve housing and, in particular, is defined there by a radial shoulder on the inner surface of the valve housing.

[0022] In particular, the first closure sleeve rests sealingly on this radial shoulder with a frontal shoulder in the closed position.

[0023] In particular, this contact is released in the open position and the first media component can flow through the annular valve opening thus released via the lateral housing passage.

[0024] In particular, the reciprocating displacement of the first closure sleeve is provided by the first spring element elastically supporting the first closure sleeve and guiding it along an outer surface of the second closure sleeve. This guidance can be realized, for example, by a sealing element, which simultaneously serves to seal the valve.

[0025] In particular, the second valve opening is arranged in the interior of the valve housing and, in particular, is defined there by a radial shoulder on the inner surface of the valve housing.

[0026] In particular, the second closure sleeve rests sealingly on this radial shoulder with a frontal shoulder in the closed position.

[0027] In particular, this contact is released in the open position and the second media component can flow through the annular valve opening thus released via the second connection.

[0028] In particular, the reciprocating displacement of the second closure sleeve is provided by guiding the second closure sleeve along an inner surface of the valve housing and along an inner surface of the first closure sleeve. This guidance can be realized, for example, by appropriately arranged sealing elements, which are simultaneously provided for sealing the first container from the second container and for sealing the valve, respectively. In particular, the first preload force and second preload force have a directional vector parallel to the longitudinal axis.

[0029] In some embodiments, with respect to the longitudinal axis, the first port is arranged at a first end of the valve housing and the second port is arranged at a second end opposite the first end.

[0030] In particular, the second connection is formed by a pin at the second end of the valve housing, which is designed for a fastening mechanism. Specifically, the second connection may have a thread intended to cooperate with a thread on or in the second container.

[0031] In particular, the second connection can also have a sealing element, in particular an O-ring, which rests against the second container when it is connected.

[0032] In particular, at the first end of the valve, one end of the first closure sleeve and / or one end of the second closure sleeve protrudes from the valve.

[0033] In some embodiments, the first spring element is also designed as a sealing element and contains in particular a thermoplastic elastomer or an elastomer, in particular a rubber.

[0034] In particular, the first spring element is essentially shaped like a tubular segment. The first spring element is particularly designed such that, upon compression along its longitudinal axis, it forms an outwardly directed bulge.

[0035] In some embodiments, the first spring element is arranged between a shoulder of the first closure sleeve protruding from the valve housing and an outer region of the valve housing.

[0036] In particular, the first spring element is arranged under a predetermined compressive stress between said closure sleeve shoulder and the valve housing outer region, i.e., it is clamped, so to speak. This preload or compressive stress presses the first closure sleeve against the first valve opening, thereby keeping it closed.

[0037] In some embodiments, the second spring element is arranged between an end face of the second closure sleeve and an inner shoulder of the valve housing. In particular, the second spring element is designed as a spiral spring, allowing the second media component to flow through the coils of the spiral spring. The use of other spring elements with similar flow characteristics is also possible.

[0038] In some embodiments, the first closure sleeve has a first sealing element, in particular a lamellar seal, for closing the first valve opening. Of course, the use of other spring elements that are permeable in this way is also possible.

[0039] In some embodiments, the second closure sleeve has a second sealing element, in particular a lamellar seal, for closing the second valve opening.

[0040] In some embodiments, the first closure sleeve has at least one first lateral sleeve passage which, in the open position of the first closure sleeve, has access to the first valve opening and leads to at least one first channel which is parallel to the longitudinal axis and located between the first closure sleeve and the second closure sleeve.

[0041] In particular, the at least one first lateral sleeve passage is provided as a transverse bore or oblique bore in the first closure sleeve. This at least one bore then leads to the interior of the tubular or hollow-cylindrical first closure sleeve. Since the second, also essentially tubular, closure sleeve is inserted into the interior of the first closure sleeve at this point, the first channel is defined by the corresponding outer wall of the second closure sleeve and the inner wall of the first closure sleeve.

[0042] In particular, the first channel is formed as a cylindrical cavity. Alternatively, such a cylindrical cavity can be divided by ribs, thereby defining a plurality of first channels.

[0043] In some embodiments, the second closure sleeve has at least one second lateral sleeve passage which, in the open position of the second closure sleeve, has access to the second valve opening and leads to at least one second channel which is parallel or concentric to the longitudinal axis and located in the interior of the second closure sleeve.

[0044] In particular, the at least one second lateral sleeve passage is provided as a transverse bore or oblique bore in the second closure sleeve. This at least one bore then leads to the interior of the tubular or hollow-cylindrical second closure sleeve. The second channel can thus be understood as the interior of the second closure sleeve. In some embodiments, the at least one first channel opens into at least one first opening on the outside of the valve, with the at least one second channel opening into at least one second opening on the outside of the valve.

[0045] In particular, the second opening protrudes beyond the first opening, which allows for simplified separate filling of the containers with the media components.

[0046] The invention further relates to a two-media component dispensing unit comprising the valve as described herein and at least one of: a dispensing actuator and the second container.

[0047] In particular, the second container is cylindrical and dimensioned such that it - like the valve - fits through an opening in the first container, which is later connected to the first connection.

[0048] In some embodiments in which the two-media component removal unit has the removal actuator, the removal actuator can be plugged onto the respective said orifices, wherein the removal actuator, in the plugged-on state, rests with a first contact surface on the first orifice and rests with a second contact surface on the second orifice.

[0049] In particular, this simultaneous contacting makes it possible for both valve openings to move into the open position simultaneously when the removal actuator is actuated.

[0050] In some embodiments, the extraction actuator comprises a mixing chamber, a first extraction actuator channel and a second extraction actuator channel, wherein the first extraction actuator channel leads from the first contact surface to the mixing chamber and the second extraction actuator channel leads from the second contact surface to the mixing chamber.

[0051] In particular, the first and the second removal actuator channel undergo a deflection, which can be 90° to the longitudinal axis, and only then lead to the mixing chamber, where the two media components come together and are mixed and, in particular, already begin to react chemically with each other.

[0052] In particular, the extraction actuator can be a spray cap or a gun or a component thereof. In some embodiments, a throttle is arranged in the first extraction actuator channel and / or the second extraction actuator channel, which throttle influences a volume flow of the respective component. In particular, a throttle is arranged only in the first extraction actuator channel.

[0053] The invention further relates to a two-media component removal system comprising the two-media component removal unit, the first container and the second container.

[0054] In particular, the two-media component dispensing system is to be understood as the complete 2K can or as a 2K can without spray cap or gun (ie dispensing actuator).

[0055] In particular, the second container is smaller than the first container.

[0056] In an exemplary embodiment, the dual-media component dispensing system also includes a lever arranged to translate movement of the dispensing actuator. This allows a user to achieve more precise operation of the dispensing actuator.

[0057] The invention further relates to a filling method of such a two-media component withdrawal system, which comprises the following steps: (a) placing a first filling connection on the first opening, (b) overcoming the first prestressing force by pressing down the first filling connection, wherein the first filling connection does not touch the second opening, (c) filling at least one propellant gas into the first container, in particular together with the first media component, (d) removing the first filling connection from the first opening, whereby the first valve opening closes again, (e) placing a second filling connection on the second opening, (f) overcoming the second prestressing force by pressing down the second filling connection, wherein the second filling connection does not touch the first opening, (g) filling at least one propellant gas into the second container, in particular together with the second media component,and (h) removing the second filling connection from the second orifice, thereby closing the second valve opening again.

[0058] In particular, any removal actuator that may still be plugged in can be unplugged before step (a).

[0059] In particular, the first media component and / or the second media component can be filled before arranging the valve on the first container and / or the second container, so that after arranging the valve on the first and / or second container, only the at least one propellant gas is filled through the valve.

[0060] In particular, the first filling connection is equipped with a shoulder designed to abut the front side of the first closure sleeve in the area of ​​the first opening. A sealing element specifically seals this point from the environment.

[0061] In particular, the first filling connection is further equipped with an interior shaped in such a way that any protruding second opening can sink into it without pressure being exerted on it parallel to the longitudinal axis. Pressing down the first filling connection therefore really only presses down the first closure sleeve, opening the first valve opening. The second closure sleeve remains stationary and the second valve opening is thus closed. This means that the media component delivered by the first filling connection can only be filled into the first container. The first filling connection is retracted, the first closure sleeve follows, i.e. moves back and the preload (compressive stress) of the first spring element keeps the first valve opening closed again.

[0062] In particular, the second filling connection is also equipped with a shoulder designed to abut the end face of the second closure sleeve in the area of ​​the second opening. A sealing element specifically seals this point from the environment.

[0063] In particular, the second opening protrudes from the valve at a distance from the first closure sleeve that is greater than the maximum adjustment travel of the second closure sleeve. This ensures that the second filling connection does not come into contact with the first opening, so that the first closure sleeve remains inactive and only the second valve opening is opened. This allows the media component delivered from the second filling connection to be filled into the second container. The second filling connection is retracted, the second closure sleeve follows, i.e., it moves back, and the preload (compressive stress) of the second spring element keeps the first valve opening closed again.

[0064] In particular, the first opening and the second opening are shaped and / or arranged rotationally symmetrically. This facilitates filling and assembly of the removal actuator because the orientation (rotational position) of the container is irrelevant. In particular, the first opening and the second opening are precisely concentric with a cylinder shell (outer diameter) of the first container.

[0065] In other words, the invention can be further described as follows:

[0066] The present invention enables the use of modern materials and sealing systems, thus ensuring compatibility with all common propellants. In particular, the lamella seal minimizes gas loss. Likewise, the lamella seal prevents the valve from sticking.

[0067] A further advantage is that the dispensing openings or orifices are centered. This eliminates the need for special positioning of a dispensing actuator during the gassing or dispensing process.

[0068] When manufacturing an aerosol product, the valve's design allows both components to be gassed individually, as it is technically possible to operate the individual valve sections individually. Alternatively, both components can be gassed simultaneously.

[0069] Such 2K valve systems offer the unique advantage that the two components are only mixed outside the aerosol can, allowing the can to be reused multiple times (a shut-off system). As a result, aerosol packaging containing such a valve can also be used for large volumes (approx. 750 ml). Existing 2K systems that are mixed inside the aerosol can typically have a maximum volume of 400 ml.

[0070] The valve is designed to dispense two liquid media components, each located in a pressure vessel and propelled by a propellant. One component is located in the outer pressure vessel, and the other component is located in a separate container within the outer pressure vessel, which is attached to the valve.

[0071] When the valve is activated, both chambers open simultaneously, and the liquid components flow through the valve opening outside the pressure vessel into the extraction adapter, where the two components mix for the first time. An application hose can be attached to the nozzle of the extraction actuator, where further mixing occurs and through which the mixture is discharged. Brief description of the drawings

[0072] Further advantages of the present invention will become apparent from the detailed description and the drawings.

[0073] Figure 1 shows a sectional view of a preferred embodiment of the valve according to the invention;

[0074] Figure 2 shows the valve from Figure 1 and sections of the first and second containers;

[0075] Figure 3 shows the valve from Figure 1 and Figure 2 with connected first and second containers with corresponding filling and a spray cap as a removal actuator; and

[0076] Figure 4 shows a two-media component removal system (as in Figure 3 but without removal actuator) and two filling connections with which the two media components can be filled separately.

[0077] Ways to implement the invention

[0078] Figure 1 shows a sectional view of a preferred embodiment of the valve 1 according to the invention. The valve 1 extends essentially along the longitudinal axis L. A first connection 7 is located at the upper end of the valve and serves for attachment or connection to a first container. The second connection 8 at the opposite, lower end serves for attachment or connection to a second container that is smaller than the first container. The second container can thus be recessed or housed in the first container, giving the outward appearance of a single can.

[0079] Generally, the valve 1 comprises a valve housing 9, which, roughly speaking, houses all other components. The first connection 7 and the second connection 8 are considered to be components of the valve housing 9. Here, the valve housing is constructed in several pieces or parts, although in other designs, a single-piece or two-piece design (e.g., as a 3D print) is also possible.

[0080] Within the housing 9, two components 10 and 14 are arranged so as to be movable relative to the housing 9 and relative to themselves. The first closure sleeve 10 is (elastically) supported on the one hand by the first spring element 11 and, on the other hand, guided by the O-ring 35 embedded in the second closure sleeve 14. The first spring element 11 is pressed in there with a defined compressive force so that it permanently presses the first closure sleeve 10 upwards using the protruding shoulder 17. This presses the first sealing element 19 against the first valve opening 12, thus closing the first valve opening 12.

[0081] The second closure sleeve 14 is guided partly within the first closure sleeve 10 and partly directly within the valve housing 9. The second closure sleeve 14 can slide, on the one hand, with the O-ring 36 on the inner wall of the housing 9, and on the other hand, with the O-ring 35 on the inner wall of the first closure sleeve 10. The second spring element 16 is clamped under a defined preload between the second closure sleeve 14 and the inner shoulder 37 of the housing 9. This presses the second sealing element 20 against the second valve opening 13, thus closing the second valve opening 13.

[0082] The special feature of this construction is that the first locking sleeve 10 and the second locking sleeve 14 can be adjusted separately and independently of each other from the shown closed position to an open position.

[0083] Figure 2 shows the valve from Figure 1 and sections of the first container 3 and second container 5. It is indicated that the second connection 8 is to be connected to the second container 5 using the screw threads and then inserted into the first container 3. Then, the first connection 7 is to be connected to the collar of the first container 3 (e.g., by crimping). This creates a two-media component withdrawal system that can be transported to a filling station (see later in Figure 4).

[0084] Figure 3 shows the valve from Figures 1 and 2 with connected first and second containers 3 and 5 with corresponding fillings 2 and 4, as well as a withdrawal actuator 34 as the withdrawal actuator. The spray cap has a mixing chamber 31, to which two withdrawal actuator channels 29 and 30 lead. Channel 29 gains access to the interior 6 of the first container 3 by pressing on the cap 34, which pushes down the first opening at the first contact surface 27, and brings the first sleeve passage 21 to the level of the housing passage 15. A propellant in the first container 3 now pushes the first media component 2 via the lateral housing passage 15, the first sleeve passage 21, the first channel 22, and the first withdrawal actuator channel 29 into the mixing chamber 31.

[0085] Similarly, when the cap 34 is actuated, the second opening on the contact surface 28 is pressed down, causing the second closure sleeve 14 to slide downward. A propellant in the second container 5 forces the second media component 4 into the mixing chamber 31 via the interior 38 of the second connection, the second spring element 16, the second sleeve passage 23, the second channel 24, and the second removal actuator channel 30.

[0086] Due to the shape of the cap 34, both closure sleeves are pressed down simultaneously. Only in the mixing chamber 31 do the two components come into contact and can be dispensed mixed together via the nozzle 39. Often, a tube or pipe is attached to the nozzle 39 (not shown in this figure).

[0087] Figure 4 shows a two-media component withdrawal system (as in Figure 3, but without the withdrawal actuator) and two filling connections 32 and 33, with which the two media components 2 and 4 can be filled separately or alternatively simultaneously. When the connection 32 moves down and abuts the first orifice 25 (at the contact surface 27, see Figure 3), the first closure sleeve 10 is pressed down until the first valve opening 12 is in the open position. The second orifice 26 can then dip unhindered into the interior 40 of the first filling connection 32. The first media component and a propellant can then be filled into the first container. The media component cannot find its way into the second container because the second closure sleeve 14 continues to close the second valve opening 13.By lifting the first filling connection 32, the first closure sleeve 10 is raised again by the pretension in the first spring element 11 and the first valve opening 12 is closed.

[0088] With the second filling connection 33, which is shown here in the background, the second closure sleeve 14 at the second opening 26 can be pressed down singly, i.e., independently of the first closure sleeve 10, thus filling the second container 5 with the second media component and propellant. By raising the second filling connection 33, the second closure sleeve 14 is raised again by the preload in the second spring element, and the second valve opening 13 is closed.

[0089] The advantage of the invention lies in particular in the simplified separate filling of the containers and in the simplified installation of an actuator (also called an application adapter). This effect is achieved by the inventive design, which allows for rotationally symmetrical orifices, i.e., inlets and outlets, on the valve.

[0090] While the invention has been described in terms of its preferred embodiment(s), many other changes and variations may be made without departing from the scope of the present invention. Therefore, it is intended that the appended claims cover such changes and variations as fall within the true scope of the invention.
