Abstract
A coaxial cartridge for storing and discharging a flowable multi-component composition, contains a hollow-cylindrical inner wall and a hollow-cylindrical outer wall arranged coaxially around the inner wall. The coaxial cartridge has an inner chamber for a first component, which is delimited radially by the inner wall, and an outer chamber for a second component, which is arranged radially between the inner wall and the outer wall. The coaxial cartridge also contains a cartridge front wall, which firmly closes the inner and the outer chamber on one end face of the cartridge and has one discharge opening per chamber; an inner and an outer piston which each close the relevant chamber at the rear and are axially movable; and an integrated reinforcement embedded inside the outer wall or fastened to its surface and having a plurality of rings or spiral turns, made of a material that is stable against tensile stresses.
