Abstract

See full text

A cartridge (1) is provided which includes an elongate tube (3) having a central body (5) that is closed at each end (11, 13) and containing a gas producing substance (30) therein. The tube (3) is made from a plastics material that is capable of outward deformation and a band (15) of an elastically deformable material is provided about the tube (3) adjacent each closed end. The tube (3) is configured such that internal pressure in the tube (3) caused by initiation of the gas producing substance (30) results in outward deformation of the body (5) and each band (15) and subsequent rupture of the body (5) prior to the closed ends being ruptured or opened.
