Definitions

  • the invention relates to a pressure cell having a frame, a dome for receiving a valve, a vaulted bottom, an inner sleeve disposed on a plate, a ram arranged in the inner sleeve for rupturing the inner sleeve, which can be actuated through the plate, and the use of such Pressure boxes for 2-component systems.
  • Such pressure cans are particularly suitable for the storage and application of 2K sealing and insulating foams, 2K adhesives and 2K paints.
  • the invention also relates in particular to the formation of pressure cans, which in addition to the liquid substances of the main component in the inner sleeve receive a second component which reacts with the main component to the finished product, such as a multicomponent varnish.
  • a second component which reacts with the main component to the finished product, such as a multicomponent varnish.
  • the invention can also be used for 2K formulations for other purposes, such as in surface technology or in the generation of plastic foams.
  • the substances contained in the pressure vessel of the main component are liquid and consist for example of a curable lacquer binder, solvents and the liquid propellant, which is used to dispense the component.
  • the further component is present in a relatively small amount in an inner sleeve and usually consists of a fast-reacting with the main component compound, such as in the 2K system polyisocyanate / polyol.
  • catalysts may be present.
  • the component in the inner sleeve serves to cure and the quality of the product to influence, usually by accelerating the curing, increasing the strength or weather resistance, or the like.
  • the second component is usually introduced shortly before the application of the foam by blowing the lid of the inner container in the pressure cell and mixed by shaking therein.
  • a pressure cell is known with a formed by forming a metal molded part one-piece bottom.
  • a recess of this bottom of the externally threaded neck of an additional container is inserted and braced by means of a nut screwed from the outside under deformation of an O-ring seal between a shoulder of the additional container and the inner edge of the bottom recess.
  • the executed in turn by a piston-shaped seal in the interior of the additional container and sealed rod is designed as a shaft which rotates in the forme knownerhals and internally supported on this. 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 cell for discharging single- or multi-component substances is described, which has in its interior a further component receiving additional container.
  • the inner container has an inner lid, which can be blasted off via a guided on the bottom of the pressure cell to the interior of the inner container rod.
  • the plunger is movably mounted within the additional container and inserted through a arranged in the sickle plate of the can bottom seal.
  • a pressure cell according to WO 85/00157 A is shown in FIG.
  • Both prior art pressure cans have an inner sleeve, which is usually made of polyolefins.
  • Preferred material is polypropylene.
  • These plastics have been proven in and of themselves, but have the disadvantage that they are permeable to some propellant gas components and solvents, such as esters, ketones and aromatics, do not sufficiently support.
  • 2-component paints usually contain such solvents, what hitherto made their use of 2-component pressurized cans very difficult.
  • these cans because of the large number of items required for the production and their construction relatively expensive and expensive to manufacture. Due to the material, in particular in the interaction of plastic metal parts, there are always tightness problems that are difficult to control and lead again and again to faulty batches.
  • the invention is therefore the object of developing the known pressure doses so that the inner sleeve forms an absolutely tight against the contents of the pressure cell unit.
  • a pressure cell of the type mentioned in which either the inner sleeve is connected via a spring cage with the plate, the spring cage contains a trigger spring-mounted, which acts on the plunger, which plunger against a arranged at the can end of the inner sleeve cover and this detaches when actuated, between plunger and Trigger a membrane is arranged, which hermetically seals the inner sleeve at its plate-side end against the contents of the pressure cell, or wherein the inner sleeve is integrally formed on the arranged in the bottom of the can plate, the plate is mounted inside the inner sleeve, a spring cage, the spring cage has a trigger springs mounted, which acts on the plunger, which arranged the plunger against a at the can end of the inner sleeve Cover acts and this breaks off when pressed.
  • the inner sleeve is now provided on the plate side with a membrane or alternatively molded onto the bottom or sickening plate, so that in this critical region a complete separation - without the use of sealing elements - is given against the remaining contents of the can.
  • the inner sleeve used in the pressure cans according to the invention can be made of 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 bottom plate, however, only a corresponding pressure-resistant material can be used in pressurized pressurized with higher pressure, preferably aluminum. The use of tinplate is also possible. The techniques with which corresponding plastic and metal parts are manufactured are known to the skilled person in and of themselves.
  • the inner sleeves of the pressure cell according to the invention are made in one piece, both as the inner sleeve with membrane and as far as the inner sleeve with molded base plate.
  • the inner sleeve is connected via a spring cage to the base or valve plate of the pressure cell.
  • the bottom plate is preferably a plate, as it is used at the valve end of the pressure cell to integrate the valve unit in the can end.
  • Such plates can be made extremely simple and inexpensive. Thus, there is the advantage that the separate production of a part is not required for the bottom 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 cage.
  • the inner sleeve has a receptacle at its plate-side end, which serves for positive and / or non-positive fixing to the spring basket.
  • the Spring basket to improve the seat may have a circumferential projection or a circumferential groove around or into which the receptacle is or deformed into. Sealing elements are not required because penetration of the can contents into the inner sleeve is reliably prevented by the membrane.
  • the membrane is expediently at the transition of the inner sleeve for receiving.
  • a trigger is resiliently mounted, which acts on the membrane, through it and on the plunger in the inner sleeve.
  • the plate end of the trigger called trigger pin - protrudes through the plate out of the pressure box.
  • Pin and trigger can form a unit, but are separated when the inner sleeve on the valve disc; the trigger in this case has a receptacle in which engages the pin for triggering the inner sleeve, and in the after release of the can and removal of the pin a valve is used.
  • the spring travel is dimensioned so that the trigger reliably drives the plunger against the cover of the inner sleeve and this effetsprengt from its anchorage.
  • a spring travel of about 5 to 10 mm is fully sufficient; by the same spring travel of the trigger pin of the plunger protrudes from the plate bottom.
  • the can is pushed with the pin against a flat and solid surface, or the pin pressed by hand.
  • the spring sleeve with at least one opening in order to facilitate the pressure equalization between the box space and the interior of the spring sleeve.
  • these openings also have the purpose of allowing rapid filling of the pressure cell with propellant gas through the spring cage.
  • the filling takes place with pressures of up to 60 bar;
  • a rapid pressure relief must be guaranteed.
  • the total cross section is expediently in the ratio of 3: 1 to 6: 1 to the free cross section of the filling device.
  • the membrane of the inner sleeve thus closes the contents of the inner sleeve during the storage time of the can reliably against the remaining contents of the can.
  • the ram drives the cover of the inner sleeve in the pressure box, so that the sleeve content is free and can be mixed with the can contents.
  • the pressure cell contains a mixing aid, for example in the form of a freely movable steel ball.
  • the inner sleeve is integrally connected to the bottom plate, d. H.
  • Inner sleeve and plate are integrally formed.
  • the spring cage is inside the inner sleeve, on the inside of the bottom plate.
  • the trigger is actuated by means of pin through the plate of the soil and acts without having to pierce a membrane, directly on the plunger, which, as described above, the lid off. Due to the formation of a unit of base plate and inner sleeve, the plate-side hermetic closure of the inner sleeve against the pressure-dose contents is also ensured here.
  • the spring basket is fixed in a central configuration of the plate. This formation encloses the end of the spring basket, which widens outward on the bottom side, and prevents the spring cage from moving into the can with the movement of the pin / trigger
  • the inner sleeve of the pressure cell according to the invention is provided on the can side with a lid, which is sealed in the usual way with a groove mounted in an O-ring.
  • the groove is expediently in a part of the lid, which projects into the valve-side end of the inner sleeve.
  • the inner sleeve in the region of the lid seal has an inner projection which cooperates directly with the protruding part of the lid and gives the seat of the lid stability.
  • the plunger has, in an expedient embodiment, several wings along a central axis, in particular four wings. This leads to a stabilization of the position of the plunger in the inner sleeve, without an excessive volume requirement arises. To further reduce the volume of the plunger, may be provided recesses or openings. Since ram and trigger form separate units at least in the first variant, a separate leadership and stabilization of the plunger is essential. In the second embodiment, ram and trigger can form a unit.
  • the lid is expedient to provide a contact point between the plunger and the lid in the periphery of the plunger, for example in that the plunger has its cover-nearest point on the periphery of a wing. In this way, the lid is applied decentrally with force, which promotes the detachment process.
  • the festerkkrimpte in the central shape spring cage acts against the seal, so that leakage of the can contents is excluded by the plate.
  • the seal for example, a rubber seal, has the form of a pierced circular disk, through the center of which the pin of the trigger protrudes from the pressure box.
