ABSTRACT:
A capsule loaded with a pressurized gas has a single front aperture sealed by an internal plug made of resilient material. The cartridge is loaded by placing it inside a pressurized chamber, then drawing the internal plug against the aperture before decompressing the chamber. A self-propelling embodiment comprises an expellable volume of liquid stored in the rear section of the cartridge in contact with its puncturable base, and separated from the pressurized gas by a floating piston. The base is concavely formed into a bell shape to focus the expelled liquid in a rearward direction.
