Abstract

A multicomponent cartridge (1) for one-time use, comprises a first supply chamber (6) for a first component (8), and a second supply chamber (7) for a second component (9), which are separate. The first supply chamber (6) is arranged coaxially around the second supply chamber (7) to form a circular space (10), wherein a first piston (3) is movably arranged in the first supply chamber (6) while a second piston (4) is movably arranged in the second supply chamber (7). A plunger (5) simultaneously moves the first piston (3) and the second piston (4) to simultaneously discharge two components (8, 9). A guide element (11) is arranged to guide the first piston (3) in the first supply chamber (6) and the second piston (4) in the second supply chamber (7). The guide element (11) includes a discharge opening (13) for discharging the first component (8) out of the first supply chamber (6), and is mounted in a housing (2). A movement element (12) moves the guide element (11) relative to the housing (2) such that a discharge opening (13) is opened.

Description

technical field

[0001] The present invention relates to a multi-component cartridge for single use, which is suitable for the simultaneous discharge of two components which are ready to be mixed before use. Background technique

[0002] Such a multi-component cartridge is already known from DE 20 2008 007 801 U1.

[0003] A disadvantage of the above described devices is that a large number of components must be used. Multi-component cartridges according to the prior art are designed both for single use and for multiple uses. However, it has been shown that after multiple uses of such multi-component cartridges the mixing may be uneven and once such a multi-component cartridge has been used for the first time it may be difficult to seal it. For this reason, multi-component cartridges which have already been used once can only be stored to a limited extent. Due to poor sealing, the filling material comes into contact with air and its properties can thereby be changed, that ...
