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.
