Abstract

A cartridge for storing and dispensing substances that are in paste form and/or capable of flow is formed by at least one tube, in which a closure piston and a dispensing piston adjustable by means of a piston rod are disposed, so as to form a seal, in such a manner that a chamber is formed between the pistons. At least one passage opening is provided in the closure piston, and at least one projection is provided in the tube assigned to this closure piston and/or an outlet opening, whereby the passage opening and the projection are adapted to one another, in terms of their shape, in such a manner that the closure piston can be displaced between a closure position, in which the chamber is closed, and a dispensing position, in which the chamber stands in a flow connection with the outlet opening, by means of the passage opening.
