Abstract
In a two-component container (,) a connection is formed between two chambers (,) by ejecting a sealing plug (,). By screwing one container (,) into a thread (,) connected to another container (,) the sealing plug (,) which is provided with two stoppers (,) is pressed out of its retaining members (,). Sealing takes place in a reliable manner by two separate stoppers (,) of the sealing plug (,). When the container (,) is screwed in, first the lower stopper (,) is ejected by the upper stopper (,) and then the upper stopper (,) is ejected by an ejection member (,). The two-component container (,) is suitable for holding peroxide and hair dye separately. After it has been ejected, the sealing plug (,) assists in the mixing of the said two components.
