Definitions

  • the invention relates to a pressure cell with a frame, a arranged in a dome valve, a bottom, an arranged on the bottom inner sleeve with absprengbarem closure and arranged in a holding element and reaching through the bottom into the inner sleeve movable shaft, the part of the trigger mechanism for the Inner sleeve is, wherein the inner sleeve is connected via the retaining element to the ground.
  • Such pressure can be used for example for the application of 2-component mounting foams or 2-component paints.
  • the invention relates to the formation of pressure cans, which in addition to the main component, which is required for the manufacture and application of polyurethane foams or paints, in the inner sleeve have a second component which reacts with the main component to the finished product, the actual foam or paint , Equally, however, the invention can also be used for 2-component formulations for other purposes, for example in surface technology and for adhesives.
  • the substances contained in the pressure vessels are usually liquid and consist of a prepolymer, conventional additives and the liquid propellant, which is used for discharging the contents of the pressure vessel.
  • the further component is present in an inner sleeve in a relatively small amount and usually consists of a compound which reacts rapidly with the main component, in the case of polyurethane prepolymers with reactive isocyanate groups, for example, a crosslinker in the form of a hydroxy compound, an amine, optionally together with catalysts.
  • the component in the inner sleeve serves to influence the curing and the quality of the product, generally accelerating the curing.
  • the second component is introduced shortly before the dispensing of the contents of the can by breaking the lid of the inner container in the pressure cell and mixed by shaking therein. The finished mixture must then be applied within a defined time to prevent curing in the can.
  • Out DE-U-82 27 229 is a pressure cell with a by forming a metal-made molded part obtained one-piece soil known.
  • 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 guided in turn by a piston-shaped seal into the interior of the additional container and sealed rod is designed as a shaft which rotates in the forme knownerhals and is supported inside 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-A-85/00157 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 through the bottom of the pressure cell into 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 corresponding pressure cell is in FIG. 1 shown.
  • Both pressure cell according to the prior art also have systemic sealing problems, which is based on the - after filling with propellant gas - automatically building pressure difference between outer prepolymer and existing in the inner sleeve hardener component.
  • this pressure difference is essentially due to the fact that the outer prepolymer penetrates into the inner sleeve. Although slow, this process involves only small amounts, so that the actual chemical reaction that leads to the curing is not affected.
  • a problem is the reaction product, which deposits in the area of the seals and in particular in the area of the lid and leads to adhesions.
  • the resulting particles in the case of a 2-component paint spray for the quality of the paint coating produced therewith are disadvantageous.
  • the invention is therefore based on the object, the pressure cell according to WO-A-85/00157 educate so that the parts of the inner sleeve can not only easier to assemble a captive and absolutely dense unit, but also to defuse the occurring due to the pressure difference occurring leakage problem between the outer space of the pressure cell and inner sleeve.
  • a pressure cell of the type mentioned above in that in the inner sleeve a movable piston member in the longitudinal direction of the inner sleeve is arranged, which seals against the inner wall of the inner sleeve and cooperates with the shaft in such a way that upon movement of the shaft into the inner sleeve the piston element is located in the inner sleeve liquid under pressure, so that the shutter is blown off.
  • Essential for the pressure cell according to the invention and in particular the operation of the inner sleeve is that the piston element is arranged to be movable inside the pressure cell.
  • the piston element is arranged to be movable inside the pressure cell.
  • the piston member moves upwardly within the inner sleeve until within the inner sleeve the pressure prevailing in the outer space of the can has been established. This eliminates the pressure difference responsible for the seepage of prepolymer into the inner sleeve.
  • the inner sleeve has a closure or lid on the valve side, which can be fitted in any manner there form fit.
  • a sealing element which may for example be in the form of an O-ring, which is mounted in a groove of the lid and engages in a groove on the inside of the inner sleeve.
  • O-ring an O-ring
  • a lip seal is preferred, which rests sealingly against the inner wall of the inner sleeve and optionally cooperates with a circumferential groove or a projection there.
  • the piston element At the bottom end of the inner sleeve is the piston element, which is preferably designed as well as the closure or the lid.
  • a sealing element located in the periphery of the piston member is a sealing element, preferably a lip seal, which acts against the inner wall of the inner sleeve.
  • groove and the like on the inner wall is not provided to allow a simple displacement of the piston member for the purpose of pressure equalization and also in the blasting of the lid.
  • blasting or "absprengbar” is to be understood according to the invention that it refers to the pushing out, pushing out or loosening of the closure element or lid at the valve end of the inner sleeve.
  • triggering refers to the activation of the inner sleeve by the breaking of the cap after actuation of the shaft.
  • the piston element preferably has on its underside a recess in a cylindrical shape into which engages the piston shaft or plunger and is supported.
  • the stem or plunger is part of the triggering mechanism and the movable element with which during the release process force is transferred from the outside of the can to the piston element and thus to the filling located in the inner sleeve, usually a more or less viscous liquid.
  • the hydraulic pressure then causes the break-off of the closure element or lid.
  • the stem is thus the central element of the triggering mechanism, but not the only element. What is essential is the more or less complete transfer of the pressure exerted by the shaft on the fluid in the inner sleeve.
  • the invention is based on the recognition that it is readily possible to dispense with a ram reaching to the cap when the pressure on the sleeve liquid can be transferred to the cap. In fact, some of the problems of pressure cans known in the art are due to the relatively rigid plunger-to-closure cap arrangement.
  • the piston solution used according to the invention allows a pressure equalization in that the piston element shifts slightly into the inner sleeve under the pressure of the prepolymer component in the outer container. The pressure is transferred according to the invention solely by the liquid column in the inner sleeve from the piston member to the cap.
  • the inner sleeve itself is mounted on a holding element which projects through the bottom of the can and accommodates the shaft or plunger in it.
  • the retaining element serves primarily as a guide for the shaft. It may, for example, be sprayed on a sickle plate, wherein the sickle plate is part of the can bottom and is crimped with a vaulted bottom element.
  • the floor element itself is crimped with the frame of the box.
  • the holding member may also be passed through a central opening in the bottom floor, which is useful especially when drawn aluminum cans.

  • Retaining elements with seal are clamped by a suitable securing element on the outside of the can bottom against the bottom of the can.
  • a securing element is for example a conventional spring washer.
  • Inner sleeve and retaining element are connected to each other, for example via suitable locking elements. It may be useful to design this compound sealing, but this is usually not necessary; to simplify the pressure balance between the contents of the can and the contents of the inner sleeve, it is expedient to allow the contents of the can to enter freely into the lower space of the inner sleeve up to the piston element. For this purpose, openings may be provided in the sleeve wall in the bottom region below the piston.
  • limiting elements on the shaft or plunger in particular an inner limiting element which limits the downward movement of the shaft towards the bottom of the can.
  • This limiting element can also be designed as a sealing element which acts sealingly against the inner wall of the holding element.
  • An approximately in height of the bottom element circumferential projection serves as an abutment for the limiting element and thus limits its downward movement. At the same time this projection causes an additional sealing effect, especially when the limiting element is designed to be elastic.
  • the shaft may have a further limiting element which limits the upward movement of the shaft when the inner sleeve is triggered.
  • this limitation is via a protruding collar, which can be braced against the circumferential projection at the level of the bottom element.
  • this outer limiting element so that it is in the assembly from above, So from the valve side, can be pushed or plugged through the holding element with its inner circumferential projection.
  • both closure and piston element have the same seal, preferably lip seal.
  • a lip seal which acts both upwards and downwards against the inner wall, also has the advantage that the piston / cover is properly guided on the wall.
  • the holding element is inventively designed as a tube-like structure through which the shaft extends from the piston element through the bottom of the can through to the outside of the can.
  • An outer peripheral projection serves to secure the retaining element on the bottom of the can, either by injection molding on the inner edge of the bottom element, or by bracing with the bottom element.
  • An inner circumferential projection in height of about the can bottom serves as an abutment for limiting elements that may be provided on the shaft.
  • the bottom end of the shaft which projects outwardly through the bottom of the can, expediently engages in a sleeve which can be actuated to trigger the snap-off mechanism.
  • An upward movement of the sleeve causes the shaft with the piston element located above it to move upwards and the closure is pushed out or blasted out by the hydraulic pressure triggered thereby.
  • the sleeve may be formed for example as a push button, which is suitably guided with a cylindrical guide on the outer wall of the outer part of the support member, but for example, be slidably mounted within a recess of a cap arranged on the bottom of the can.
  • the retaining element has on its bottom-side part concentrically around the shaft an internal thread into which engages a sleeve with an external thread.
  • the bottom end of the shaft extends into a central bore of the screw. Screwing the sleeve into the retaining element thus causes the upward movement of the shaft and piston element and thus the triggering of the inner sleeve.
