ABSTRACT:
The device for mixing and dispensing multi-component compositions is distinguished in that a cap (10) acting as a closure initially closes the outlet openings (5) of the components and can be moved into the open position by pressure of the components while they are being discharged, so that the components can be mixed by the mixing helix (13) and emerge from the outlet tube (12).
