Abstract: A spray gun is provided with a handle part (6) and a housing (2) having a connecting part (3) for a pressure can, said connecting part being provided with a check valve. The housing (2) receives a nozzle pipe (10) bearing a nozzle (11) at the free end, into which pipe a spring-loaded nozzle needle (12) acting upon the opening of the nozzle (11) extends. The nozzle needle is operable via a pivoted lever (9) mounted in the housing (2). To permit the position of the pressure can to be varied and fixed relative to the handle part (6) while involving a simple structure, the housing part (17) bearing the connecting part (3) for the pressure can is adapted to be rotated around the axis (19) of the nozzle needle (12) relative to the housing part (18) bearing the handle part (6).

Abstract: A two-component pressure container is provided. The pressure container comprises a valve, an outer container for a first component and a foaming agent as well as an inner container sealed against the outer container for the second component and eventually another foaming agent, in which the outer container is provided with a tube extending towards the bottom of the box. The inner container is affixed in a detachable manner and hermetically sealed against the outer container by sealing elements, and in which, by actuating the valve from the outside, the inner container can be opened into the outer container. Such a two-component pressure container is particularly suitable to produce two components foams, e.g., polyurethane foams.
