Pressured container for delivering assembly foam, especially one-component polyurethane foam

摘要

In the case of a pressure can for dispensing assembly foams, in particular one-component polyurethane foam, the frame of which has a cylinder, a preferably indented bottom and a dome-like upper part with a closure, into which a valve for dispensing the can filling consisting of a blowing agent and foaming agent is inserted, to limit the Propagation of propellant gas in the atmosphere and to facilitate the application technology proposed that the inside of the wall of the cylinder of the frame leads the shirt of an overhung piston which is overhung between the propellant or foaming agent filling housed in separate can spaces and that of the Can bottom and a variable lower length of the cylinder wall enclosed propellant gas space from the overlying, the foam-forming space that is enclosed by the piston crown and the remaining length of the cylinder and the closure.
