Definitions
- Pressure can for mixing and dispensing two-component materials
- the invention relates to a pressure can with a frame, a dome for receiving a valve, a domed bottom, an inner sleeve arranged on a plate, a plunger arranged in the inner sleeve for bursting open the inner sleeve, which can be actuated through the plate, the inner sleeve via a spring cage is connected to the plate, the spring cage contains a spring-loaded trigger which acts on the plunger, which plunger acts against a closure arranged at the end of the inner sleeve on the can side, and the use of such pressure sockets for two-component systems.
- Pressure sockets of this type are particularly suitable for the storage and application of two-component sealing and insulating foams, two-component adhesives and two-component paints.
- the invention also relates in particular to the formation of pressure cans which, in addition to the liquid substances of the main component, accommodate a second component in the inner sleeve, which reacts with the main component to form the finished product, for example a multi-component lacquer.
- the invention can also be used for two-component formulations for other purposes, for example in surface technology or in the generation of plastic foams.
- the substances of the main component contained in the pressure vessel are liquid and consist, for example, of a curable paint binder, solvents and the liquid propellant gas which is used to apply the component.
- the other component is present in a relatively small amount in an inner sleeve and usually consists of a main Fast-reacting component, for example in the 2K polyisocyanate / polyol system. If necessary, catalysts can be present.
- the component in the inner sleeve serves to influence the hardening and the quality of the product, generally by accelerating the hardening, increasing the strength or weather resistance, or the like.
- the second component is introduced into the pressure can shortly before the foam is released by blasting off the lid of the inner container and mixed therein by shaking.
- DE 82 27 229 U discloses a pressure cell with a one-piece base obtained by shaping a molded part made of metal.
- the neck of an additional container which is provided with an external thread, is inserted into a recess in this base and clamped between a shoulder of the additional container and the inner edge of the base recess with the aid of a nut screwed on from the outside and deforming an O-ring seal.
- the rod which in turn is designed and sealed by a piston-shaped seal in the interior of the additional container, is designed as a shaft which rotates in the additional container neck and is supported on the inside thereof. If the shaft is driven from the outside, this leads to the positive engagement of its inner end with the lid of the additional container, which is thereby blasted off against the internal pressure in the can.
- the starting point of the invention is WO 85/00157 A, in which a pressure can for dispensing single- or multi-component substances is described, which has an additional container accommodating a further component in its interior.
- the inner container has an inner lid which can be blasted off via a rod which is guided onto the bottom of the pressure cell and into the interior of the inner container.
- the plunger is movably mounted within the additional container and inserted through a seal arranged in the crimp plate of the can base.
- a pressure can according to WO 85/00157 A is shown in FIG. 1.
- Both pressure cans according to the prior art have an inner sleeve which is generally made from polyolefins.
- the preferred material is polypropylene.
- These plastics have proven themselves in and of themselves, but they do the disadvantage that they are permeable to some propellant gas components and do not withstand solvents such as esters, ketones and aromatics sufficiently.
- 2-component paints in particular generally contain such solvents, which previously made their use from 2-component pressure cans very difficult.
- these cans are relatively complex and costly to manufacture. Due to the material, especially when plastic-metal parts interact, there are always tightness problems that are difficult to control and lead to incorrect batches.
- a pressure can is known which is already improved with regard to the construction of the inner sleeve and which solves the sealing problem in the plate area by means of a molded membrane or an integration of the plate into the inner sleeve, so that no seals are required in this position ,
- the inner sleeve still has a conventional cover, which requires an O-ring for sealing.
- 2-component coating systems which contain aromatics as a solvent and polyisocyanates as the second component, there is a not inconsiderable immigration of both components into the sealing system with long storage times and / or high temperatures, which can lead to problems when the cover is detached.
- the invention is therefore based on the object of developing the known pressure sockets in such a way that their inner sleeve forms an absolutely sealed unit against the content of the pressure socket.
- a pressure can of the type mentioned at the beginning in which the closure is a membrane which hermetically seals the inner sleeve at its can end against the contents of the pressure can, and which is torn open by the plunger when the trigger is actuated.
- the inner sleeve is now equipped on the can side with a membrane, so that in this critical area there is complete separation - without the use of conventional separate sealing elements, for example O-rings - from the remaining can contents, and the membrane can be glued to the inner sleeve or as an integral part of the inner sleeve forms, ie the inner sleeve and membrane are made in one piece.
- the membrane itself preferably has a circumferential edge which, when the membrane is placed on, engages around the inner sleeve by a distance, for example a few millimeters, and is adhesively bonded.
- the edge can also be provided with an internal thread and screwed to an external thread of the inner sleeve at the end on the can side; in this case, too, the sealing effect is brought about by the use of an adhesive.
- conventional two-component adhesive systems are suitable as adhesives, for example amine-curing epoxy adhesives or amine- or OH-curing polyisocyanate adhesives.
- adhesives for example amine-curing epoxy adhesives or amine- or OH-curing polyisocyanate adhesives.
- the choice of adhesive depends on its resistance to the respective can contents; the most suitable adhesive system can be determined by simple tests.
- the inner sleeve used in the pressure sockets according to the invention can be made from conventional materials, but preferably consists of aluminum. Plastic variants, for example made of polypropylene, are also possible. Where the inner sleeve is an integral part of the base plate, however, only a correspondingly pressure-resistant material, preferably aluminum, can be used in the case of pressure cans subjected to higher pressure. The use of tinplate is also possible. The techniques with which corresponding plastic and metal parts are manufactured are known per se to the person skilled in the art.
- the inner sleeve is connected to the base plate or valve plate of the pressure cell via a spring cage.
- the base plate is preferably a plate as used at the valve end of the pressure cell to integrate the valve unit into the can dome.
- Such plates can be manufactured extremely simply and inexpensively. This has the advantage that separate manufacture of a part is not required for the base plate.
- the arrangement of the inner sleeve on the valve plate in the dome of the can is particularly advantageous. In this case, the bottom plate can be omitted.
- the inner sleeve with membrane is connected to the plate via a spring basket.
- the inner sleeve has a receptacle on its plate-side end, which is used for positive and / or non-positive fixing on the spring cage.
- the receptacle and the spring cage are expediently clinched or crimped to one another, the spring cage being able to have a circumferential projection or a circumferential groove to improve the fit, around or into which the receptacle is deformed or deformed. Sealing elements are not required since the membrane can reliably prevent the contents of the can from penetrating into the inner sleeve.
- a second molded membrane is expediently located at the transition from the inner sleeve to the receptacle, which is used as described below.
- a trigger is resiliently mounted within the spring sleeve and acts on the second membrane, through it and on the tappet in the inner sleeve.
- the plate-side end of the trigger - referred to as a trigger pin - protrudes through the plate and out of the pressure cell.
- the pin and trigger can form a unit, but are separated when the inner sleeve is arranged on the valve plate; in this case the trigger has a receptacle into which the pin engages to release the inner sleeve and into which a valve is inserted after the can has been released and the pin has been removed.
- the spring travel is dimensioned so that the trigger reliably drives the plunger against the (first) membrane of the inner sleeve and tears it open.
- a spring travel of about 5 to 10 mm is fully sufficient; the release pin of the plunger protrudes from the plate base by the same travel.
- the can is pushed against a flat and firm surface with the pin, or the pin is pressed in by hand.
- the spring sleeve with at least one opening in order to facilitate pressure equalization between the can space and the interior of the spring sleeve.
- these openings also have the purpose of allowing the pressure can to be filled quickly with propellant gas through the spring cage.
- the filling takes place with pressures of up to 60 bar;
- a rapid pressure relief can be guaranteed. This takes place through the openings, the total cross section of which is expediently in the ratio of 3: 1 to 6: 1 to the free cross section of the filling device.
- the membranes of the inner sleeve thus reliably close the contents of the inner sleeve against the remaining contents of the can during the storage period of the can.
- the second membrane is pierced.
- the plunger tears open the first membrane of the inner sleeve, so that the contents of the sleeve become free and can mix with the contents of the can.
- the pressure cell it makes sense for the pressure cell to contain a mixing aid, for example in the form of a steel ball which can move freely therein.
- the inner sleeve is also anchored to the base plate.
- the spring cage is located inside the inner sleeve, on the inside of the base plate.
- the trigger can be actuated by means of a pin through the plate of the base and, without having to pierce a membrane, acts directly on the plunger, which, as described above, tears open the membrane.
- the formation of a unit consisting of a membrane and an inner sleeve ensures that the inner sleeve is hermetically sealed against the pressure cell contents. On the bottom side, the hermetic seal results from the fact that the inner sleeve and the curved bottom, as well as the bottom plate, are crimped together, including sealing elements.
- the inner sleeve and (first) membrane can also be glued to one another, as previously described.
- the spring cage is fixed in a central shape of the plate. This shape encloses the end of the spring basket which widens outwards on the bottom side and prevents the spring basket from moving into the can with the movement of the pin / trigger.
- the tappet has a plurality of vanes along a central axis, in particular four vanes. This leads to a stabilization of the position of the tappet in the inner sleeve without an excessive volume requirement. In order to further reduce the volume of the tappet, cutouts or openings can be provided. Since the plunger and trigger form separate units, at least in the first variant, separate guiding and stabilization of the plunger is essential.
- the tappet for example, the shape of a bevelled and sharp-edged hollow cylinder at its end on the membrane side, possibly with a tip.
- the tappet there is a contact point between the tappet and the membrane on the periphery of the tappet, which is suitable for perforating the membrane there first and then punching out or cutting an approximately circular opening as the tappet is advanced further.
- the inner container Since the inner container is hermetically sealed against the remaining contents of the can and is filled separately, there is automatically a pressure difference between the contents of the can and the contents of the inner sleeve. As a result, the membrane is under pressure and bulges into the inner cylinder, which leads to the membrane contacting the tappet in the area of the tappet closest to the tappet. This application promotes the tearing open of the membrane.
- the tappet is expediently beveled at its diaphragm-side end, so that a point closest to the diaphragm is created, and has four wings for stabilization within the inner sleeve.
- this four-wing variant is usually completely open.
- the membrane is cut open in a cross shape and tears open completely under the pressure of the contents of the can, so that rapid mixing occurs.
- the central Forming crimped spring basket acts against the seal, so that an escape of the can contents through the plate is excluded.
- the seal for example a rubber seal, has the shape of a pierced circular disk, through the center of which the pin of the trigger protrudes from the pressure cell.
- the trigger has a projection on its plate-side end, which, expediently with a projecting edge, acts against the perforated disk-shaped seal in the plate and also seals off to the outside in the area of the pin.
- the trigger has a further projection on the plate side, directly after the sealing projection, which serves as an abutment for the helical spring guided in the spring cage.
- An inner projection arranged on the valve-side end of the spring cage serves as a further abutment.
- the pressure cell according to the invention is otherwise manufactured and equipped in a conventional manner. This also applies in particular to the valve area and the valve-side equipment that allows the pressure cell to be used both in manual operation and as a cartridge on spray guns.

- Figure 5 shows a trigger for an inventive
- Figure 6 shows an inner sleeve for a pressure cell according to the invention for arrangement on a valve plate
- FIG. 7 shows the plate area of the embodiment according to FIG. 6.
- Figures 1 to 7 are sectional figures.
- the pressure cell 1 consists of a frame 2 which is closed at the upper end with a dome 3.
- the dome 3 has a flanged edge which connects the dome and the frame to one another and at the same time brings about a tight connection of the parts.
- the dome 3 is made from a round plate, a molded part cut out of sheet metal, which has been given the arched shape shown in the drawing by shaping.
- the inner edge of the dome 3 is in turn flanged and receives a valve plate with a valve 4.
- the base 5 is also connected to the frame 2 via a flanged edge and has a base plate 6 in the center, above which the inner sleeve 7 is located.
- the inner sleeve 7 has a detachable cover 8. Inside the inner sleeve 7 . there is a plunger 9, the end of which is guided out of the pressure cell at the bottom by a sealing element 10.
- the plunger 9 has limiting elements on both sides of the sealing element 10, both of which act against the sealing element 10 and limit the free path length of the plunger 9 within the inner container 7. To detach the lid 8 from the inner container 7, the plunger 9 is pressed into a solid surface by striking the bottom of the can and set in an upward movement.
- the can according to FIG. 1 can be equipped with the inner sleeves according to FIG. 2, 3 or 6.
- FIG. 2 shows an inner sleeve 7 manufactured according to the invention and used, with a plunger 9 and cover 8.
- the inner sleeve 7 has a cylindrical wall and is closed off on the plate side by a membrane.
- a cylindrical receptacle 18 adjoins the plate and serves to fix it on the spring cage 11.
- the inner sleeve can be made of a suitable plastic, but is expediently made of aluminum.
- suitable wall thicknesses for the wall are approximately 0.3 to 0.8 mm, for the two membranes approximately 0.05 to 0.10 mm.
- the inner sleeve 7 is closed with a first membrane 8, which can be made of aluminum or plastic.
- the membrane 8 has an edge 25 all around, which extends over the outer edge of the inner sleeve 7. Between the edge 25 and the outer wall of the inner sleeve there is a gapless layer of an adhesive 24 which is resistant to the contents of the can (both outer can and inner sleeve).
- the plunger 9 guided in the inner sleeve 7 has four wings 17 which are cut out laterally to reduce the space requirement.
- On the plate side there is a plate-shaped closure which is located directly on the can side of the second membrane 15.
- On the can side the plunger 9 is chamfered in such a way that it has its point 16 closest to the membrane in the periphery; when the plunger 9 is actuated, the membrane is pierced there first.
- the beveled cylindrical design of the plunger end 16 as a hollow cylinder with sharp edges then leads to a cylindrical opening being punched out / cut from the membrane 8.
- the spring cage 11 itself consists of a plastic sleeve which is provided at its socket-side end with an inner circumferential projection 21 which serves as an abutment for a helical spring 13 mounted therein.
- the coil spring 13 is supported on the plate side on a circumferential projection 22 of the solver 12. In the rest position, the spring 13 exerts a pressure on the trigger 12, so that it is pressed with its sealing seat 23 against the ring seal 20 arranged in the plate 6.
- the trigger 12 ends at its end protruding from the plate 6 in a bolt 14 which protrudes from the can by the length that the trigger 12 has to be pushed in to blow off the cover 8 via the plunger 9.
- the spring sleeve 11 has an extension 27 on the plate side, which engages behind the inner shape 19 of the base plate 6 and ensures an immovable fit on the base plate 6.
- the base plate 19 which has the shape of a valve plate of a conventional aerosol can, is crimped around the seal 20 and the spring basket 11 placed thereon. The crimping process ensures a firm bond between plate 6, spring basket 11 and sealing rubber 20, due to the interaction of the indentation 28 of the plate 6 and the extension 27 of the spring basket 11.
- the trigger 12 is divided into the section located within the spring cage and a protruding pin 14, via which the triggering process is controlled.
- a tip 29 is located directly adjacent to the second membrane 15 and acts when actuated against the bottom end of the plunger 9.
- the second membrane 15 is destroyed, which promotes the leakage of the contents of the inner sleeve into the can and the mixing of the two components.
- a circumferential sealing seat 23 (FIG. 5) which projects out from the pin 14 and acts with its protruding edge against the seal 20.
- FIG. 3 shows a second variant of an inner sleeve of a pressure cell according to the invention, in which the inner sleeve 7 and membrane 8 are integrally connected to one another.
- the inner sleeve 7 is completely sealed off from the remaining can contents on the can and plate side.
- Tappet 9 and spring cage 11 have the rest of the structure shown in Figure 2 and the same operation.
- the membrane 15 is missing. A tip on the trigger 12 for penetrating the second membrane provided in FIG. 2 is therefore no longer necessary.
- inner sleeve 7 is preferably made in one piece according to FIG. H. Inner sleeve 7 and membrane 8 are not subsequently connected to each other.
- the wall thicknesses of sleeve 7 and membrane 8 are also in the range from 0.3 to 0.8 mm. Gluing or soldering the inner sleeve and membrane is also possible.
- the inner sleeve 7 is crimped to both the bottom part 5 and the plate 6 with the introduction of the usual seals.
- the spring cage is introduced into the base plate 6 in the manner described above.
- the plunger 9 is four-winged to ensure proper guidance within the inner sleeve 7, the wings being cut out in the central area.
- the four wings are completely formed and beveled uniformly so that a diaphragm point 16 is formed, which initiates the tearing process on the diaphragm 8 when the trigger and plunger are actuated.
- the tearing process is due to the pressure prevailing in the can, which is significantly higher than that in the inner sleeve, and a bulging of the membrane 8 into the inner sleeve, so that it contacts the pushrod cross in the area of the next point 16 of the tappet created, promoted.
- FIG. 4 shows a spring cage 11 which can be used according to the invention with an abutment 21 on the socket side for the helical spring mounted therein and an extension 27 provided on the plate side for crimping and fixing on the base plate 6.
- the extension 27 in the form of a circumferential bead is accompanied by a cut 30 am inner edge and formation of a peripheral edge 31 which is pressed against the rubber seal 20 during the crimping process with the plate 6.
- FIG. 5 finally shows a trigger 12 used according to the invention with a tip 29, the abutment 22 for the helical spring, the Pin 14 and the sealing seat 23 projecting relative to the part of the trigger and the pin 14 mounted in the spring, but recessing relative to the abutment 22, which is provided with a circumferential edge acting against the seal 20; in the sectional view, this is shown as a slight undercut.
- FIG. 6 shows a further preferred embodiment of an inner sleeve 7 to be used according to the invention with an arrangement on a valve disk 6.
- the arrangement of the inner sleeve on the valve plate 6 has the advantage that the aerosol can does not have to have a specially designed base area.
- the inner sleeve 7 with plunger 9 and cover 8 has the second membrane 15 on the plate side, which hermetically seals the inner sleeve on the plate.
- the inner sleeve 7 On the bottom side, the inner sleeve 7 has a membrane 8 screwed thereon, the outer wall of which is provided with an internal thread which interacts with an external thread on the inner sleeve 7.
- the thread area is provided with an adhesive layer throughout for hermetic sealing.
- the construction of the inner sleeve according to FIG. 6 corresponds to that in FIG. 2.
- the inner sleeve 7 is plugged with its receptacle 18 onto the can-side end of the spring cage 11, so that detachment when the trigger 12 is actuated is excluded.
- the connection expediently takes place in that the receptacle 18 is linked to the spring cage 11, preferably in such a way that the free end of the receptacle 18 is guided around an outer circumferential projection 32 (see FIG. 7) of the spring cage 11.
- the spring cage 11 with the trigger 12 is also part of the valve mechanism, it is expedient to remove the to physically separate solver 12 from trigger pin 14.
- the trigger 12 has a receptacle 33 for the trigger pin 14, which receives the trigger pin for the triggering process, but from which the trigger pin can be pulled out again after triggering.
- the same receptacle then takes up a conventional spray head as used for aerosol cans. So-called female valves with lateral slots and a pin which projects into the receptacle 33 are preferred.
- the pressure can contents can flow through the opening (s) 34 into the spring cage and can be removed from the pressure can by the actuated valve 4.
- the openings 34 have a further function in connection with the filling of the can.
- the filled inner sleeve with the valve plate is applied to the can dome and crimped with it.
- the can is filled with the propellant gas through the valve opening, usually propane, butane, dimethyl ether and / or fluorocarbon (134a).
- the can is filled with a pressure of up to 60 bar in order to keep the process as short as possible.
- a pressure of up to 60 bar there is a risk that the membrane 15 will burst under this pressure itself or through the action of the pressure-operated trigger 12. In order to counter this danger, the gases must be released as quickly as possible after entering the can.
- Such relaxation is achieved by arranging one or more larger passage openings 34 in the spring cage 11. It is expedient to provide these through openings 34 with an overall cross section which corresponds to three to six times the free cross section of the filling needle through which the propellant gas flows into the pressure cell.
- the openings 34 in the valve cage 11 are provided on the plate-side end of the valve cage, as close as possible to the valve itself.
- the valve-side sealing is carried out by a pre-provided on its plate-side end see sealing seat 23 in the form of a circumferential projection, which acts against the seal 20 between the spring cage 11 and plate 6 in the region of the central formation 19.
- the distance of the trigger 12 to the membrane 15 must be reflected in the length of the trigger pin 14, such that the trigger pin has an overall length that the distance of the trigger 12 to the membrane and further on the path of the plunger 9, the this must cover to tear the membrane 8 corresponds.
- the travel is designed to be correspondingly long.
- FIG. 7 shows an illustration of the spring cage with trigger 12 according to FIG. 6 in detail.
- the valve plate 6 has a shape 19 in its central area with an opening, into which a seal 20 in the form of a perforated circular disk, preferably made of a rubber-like material, is inserted on the can side.
- the spring cage 11 is fixed via its extension 27.
- the peripheral edge 31 arranged on the head side acts against the rubber seal 20 and seals the contents of the can against the central opening in the plate and in the seal 20.
- the crimping process during the molding of the spring cage 11 into the central molding 19 of the valve disk 6 means that the individual components are connected to one another in a positive and non-positive manner and in a sealing manner.
- the free end of the receptacle 18 is guided around an outer circumferential projection 32 of the spring cage 11.
- the spring cage 11 has openings 34 immediately below the fixing on the valve plate, which allow the contents of the can to penetrate into the spring cage.
- the coil spring 13 Inside the spring cage H is the coil spring 13, which is supported on an inner projection 21 of the spring cage 11 and against an outer projection 22 of the trigger 12.
- the helical spring 13 presses the trigger 12 with its circumferential edge 23 against the sealing rubber 20, so that the pressure cell is closed in this state.
- the trigger pin 14 is inserted into the recess 33 of the trigger 12 and pressed down vigorously so that the trigger 12 pierces the membrane 15 with its tip 29 and moves the plunger 9 below it against the membrane 8.
- the trigger 12 After the release has taken place, the trigger 12 returns to its rest position, so that the can remains closed to the outside.
- the sealing takes place through the interaction of the flanks of the trigger pin with the rubber seal 20.
- a conventional valve is inserted into the recess 33, which valve is actuated by being pressed in.
- the trigger moves a defined way into the can, so that the can contents can pass through the openings 34 unhindered into the spring cage and out of the valve.
- the openings 34 also have the purpose of filling the already closed can with propellant gas through the central opening in the seal 20, so that the propellant gas can quickly get into the can contents.
- the propellant gas is pressed into the spring sleeve at the intended pressure, so that the trigger 12 moves a defined distance in the direction of the diaphragm 15 without reaching it, however, so that after the Openings 34 allow the gas to escape laterally into the can while relaxing.
- Pressure cans according to the embodiment according to FIG. 6 are used "upside down” during use, that is to say the valve points downwards.
- Pressure sockets according to FIGS. 2 and 3 can be used upright when a riser pipe is inserted, or “upside down” if there is no riser pipe. The use with spray guns is possible and intended.
