Abstract (en)
[origin: WO2013150462A1] A cartridge (10) is provided having a receptacle (12) with propellant (14) therein and an open end with a stemming device (16) secured to the open end to form a substantially closed container. The stemming device (16) is operable to result in radial expansion thereof and has a static member (18) secured to the receptacle (12) and a piston (20) movable, at least partially within the container, relative to the static member (18) and the receptacle (12). The cartridge is configured such that ignition of the propellant (14) causes movement of the piston (20) to operate the stemming device (16) and cause radial expansion thereof before the receptacle (12) ruptures.
