Abstract

In a two-component container (1), a connection between two chambers (6, 7) can be produced by the ejection of a stopper (5). By screwing the one container (3) into a thread (4) connected to another container (2), the stopper (5) is ejected out of its retaining element (14). An intermediary piece (19) is provided between the containers (2, 3) and rests with a support (20) on the upper rim (21) of the lower container (3). A sealing lip (30) between the connecting piece (10) and the intermediary piece (19) can be deflected elastically outward so that it produces a valve action in the event of an overpressure in the two-component container (1). The two-component container (1) is suited for separately storing peroxide and hair color.
