Abstract
A cartridge for use in an extension tool is arranged to receive one or more foil bags containing a single component or a multi-component mass and is formed of a cylinder (3) defining one or more receiving chambers (13) open at the opposite ends thereof. An axially displaceable piston (5) has opposite end faces (5b, 5c) extending across the cylinder (3) and each end face is symmetrical about its axis. The end faces of the piston can be used alternately for dispensing the mass out of the one or more foil bags.
