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).
Claims20
A device for mixing and dispensing multi-component compositions, in particular for dental purposes, with a cartridge with at least two cylindrical chambers arranged in parallel for receiving the components and in each case a plunger for discharging the components, the chambers having outlet openings which are covered by a cap, which has an outlet tube enclosing a mixing helix, the cap being movable from a position closing the outlet openings into a position releasing them, wherein the cap can be moved into the open position by the pressure of the components while they are being discharged and a transverse wall which extends toward the cap and on which the mixing helix is fitted is provided on the cartridge between the outlet openings.
