Definitions

• the invention relates to a pressure can with a container and a metering valve arranged in a container opening for the separate reception of components for a mixture or compound before their use.
• the separation of the components is also expedient if, when combined, they develop special properties, for example foams.
• foams In the case of such mixtures or compounds as well, it is known to store the components separately and to add them together only when in use.
• An example of this are the known polyurethane foams, which are used as materials in many fields of work. They essentially consist of two Grundkompone 'nth and- from small amounts of additives which one of the two components are admixed. 'If you combine the two components and mix them together, the polyurethane foam develops.
• the invention is based on the object of designing a pressure can of the type described at the outset in such a way that storage of any length is ensured and the components can be combined in the simplest manner, the processing of the mixture or the compound also being carried out without problems when in use ⁇ can be performed.
• At least one closed container containing a component is mounted in the range of movement of the metering valve or a movement member actuated by the metering valve such that it is actuated by the valve or of the movement member opens and releases the component for mixing with the further component or the further components.

• the valve 20 has a valve body 21 extending through the opening 16 with an inner valve seat body 22 and a spring and guide sleeve 23, in which a valve stem 24 with a longitudinal channel 25 is arranged.
• the valve stem 24 has a collar 26 on which the spring and guide sleeve 23 of the valve body 21 is supported, and an inside flange end 27, the outer edge of which seals the valve with the valve seat body 22. Outlet openings 28 are arranged in the valve stem 24 directly on the flange end 27. When the valve stem 24 is tilted, the flange end 27 is

• the design of the valve is of secondary importance. It is only necessary that a movable part, in FIG. 1 the valve stem 24 with the flange end 27, of the valve 20 ′′ projects into the interior of the can 2.
• the connecting part 15 is formed in FIG. 1 as a sleeve 35, one end of which has an inwardly drawn-in shoulder 36, which forms an opening .37.

• a container 40 is inserted, which is supported on the shoulder 36.
• the container 40 contains a component of the mixture or compound to be made for use. It is also possible to insert more than one container 40 into the sleeve 35.
• the container 40 of glass or other material that destroy by pressure or can be opened, for example at a predetermined breaking point '. The opening takes place by opening the valve 20 in that the valve stem 24 is pressed against the container 40, as a result of which the container or containers 40 are destroyed or opened by the flange closure 27.
• the contents of the container or containers 40 are emptied through the Mouth 37 and comes together with the component filled in the can 2 and can by shaking in this be distributed evenly, creating the desired mixture or compound.
• connection part 15 is also designed as a sleeve 35, but in its cylindrical or conical part it has a double bead 41 ' and a concave shoulder 36 ', to which a connecting piece 42 connects.

• a movement member 45 which in FIG. 2 is a plate 46 with an opening 47, is used to transmit the movement of the flange end 27 of the valve stem 24.
• the plate 46 can also be different, e.g. cruciform or wheel-shaped.
• the openings in the movement member 45 serve for the passage of the mixture or connection when the valve 20 is actuated.
• the plate 46 When the valve stem 24 is actuated, the plate 46 is pressed against the container 40, which is destroyed or opened in the process. The component runs into the concave part of the shoulder 36 and merges with the component in the container 40 via the openings 43.
• the slots 43 are usually closed or only slightly opened so that the pressure equalization between the can and the interior of the sleeve 35 can take place. If the plate 46 is pushed onto the double bead 41, the sleeve 35 is deformed in the lower region, as a result of which the slots 43 are opened. The plate 46 is held in the bead 41. If the valve stem .24 is pressed further, the

If the plate 46 is snapped into the double bead 41, the component flows out of the destroyed or opened container 40 through the openings 43. A membrane 49 is provided so that the liquid cannot flow through the nozzle 42. When the outflow of the component through the openings 43 has ended, the plate 46 is brought into the position shown in FIG. 4 below the double bead 41, in which it closes the openings 43. If the can contents are processed after the components have been mixed, the membrane 49 is destroyed by the internal pressure of the can, and the can contents can be processed.
