Claim 0:
1. A multichamber vessel for storing and mixing a multicomponent liquid coating or adhesive system (M) having a first chamber for a first mixture component (B) and at least one further chamber for a further mixture component (H), where the first chamber and the at least one second chamber are divided from one another in a liquid-tight manner by at least one dividing wall, where the at least one dividing wall comprises a penetrable dividing layer, and having at least one penetrating element for penetrating the penetrable dividing layer in such a way that the first and further mixture components (B, H) mix in the first or the at least one further chamber,
wherein
the at least one further chamber is arranged coaxially relative to the first chamber, where the first chamber further takes the form of an outer vessel, where the at least one further chamber is designed as an insert in the form of a cup in the outer vessel, where the penetrable dividing layer forms part of the area of the at least one dividing wall, where the at least one penetrating element is in hollow form and has at least two longitudinally offset openings for introduction of one of the first or further mixture components (B, H) into the chamber of the respective other mixture component (H, B), where the at least one penetrating element is further braced on a curved brace surface which moves from a first location to a second location when a force above a pressure threshold is exerted, in such a way that the at least one penetrating element is moved from a first position to a second position at the transition from the first to the second location, where the at least one penetrating element penetrates the penetrable dividing layer.
