Multicomponent cartridge for single use

摘要

A multicomponent cartridge which is designed for single use includes two separate supply chambers arranged coaxially of each other and two pistons. The two pistons are movable via a plunger to simultaneously discharge two components. A guide element guides the two pistons in the respective supply chambers and contains a discharge opening for discharging the first component. The guide element is movable relative to a housing via a movement element in order to open the discharge opening.
