An ejection device for a mass-containing package () includes at least one piston rod () having a toothing () extending along its longitudinal extent, and a drive unit () for displacing the at least one piston rod () and having at least one gear wheel () engageable with the toothing () of the at least one piston rod () and displaceable from a first position, in which it engages the toothing () of the at least one piston rod (), to a position in which it is disengaged from the toothing () of the at least one piston rod, and a drive motor () for driving the at least one gear wheel ().

Ejection device

An ejection device () for cartridges containing multi-component compounds has an ejection mechanism () and a receptacle () for the cartridge, with the receptacle () being limited on the front side by a head plate () and on the rear side by a stop plate () and in order to hold the cartridge in a first position, a first stop () provided at the head plate () and a second stop () provided in the area of the stop plate (), and a third stop () in order to hold the cartridge in a further position.

A cartridge () used as a container for a compound that can be ejected by an ejection device, has two receptacles () and a head part (), each receptacle () having a receptacle chamber () for components of the compound with the head part () having a base plate () with an outlet opening () for the compound and, at a contact surface () of the base plate (), two guide portions () for joining to an end () of the corresponding receptacle (), a guide element for the receptacle () arranged adjacent to the guide portion () at the contact surface () of the head part ().
