Abstract: This invention relates to a non-detonating cartridge containing an explosive composition, and more particularly but not exclusively to a non-detonating cartridge having enhanced safety characteristics. The cartridge includes a container including a cavity suitable for receiving a low explosive composition; an initiator, for in use initiating the explosive composition inside the cavity; and a shielding member which is displaceable relative to the container between a safe position, in which the initiator is shielded from the cavity such that initiation of the initiator does not result in initiation of the explosive composition, and a live position in which the initiator is exposed to the cavity to permit initiation of the explosive composition. The cartridge is characterised in that the shielding member is slideably displaceable relative to the container.

Abstract: 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.
