ABSTRACT:
A pressurized can for the expulsion of building foams such as single-component polyurethane foams, the body of which is a cylinder, with a preferably pushed-in bottom. The body also includes a dome-like top section with a valve which expels the can contents consisting of a product component and a propellant. A floating plunger mounted on the interior wall of the cylinder separates the propellant gas chamber from the product component. The floating plunger has a cavity in its upper side, in which a component reactive with the product component is sealed off from the product component by a seal. A trigger device is placed in the dome-like top section to open the seal when the plunger reaches a position immediately below the dome-like top section.
