Abstract
Unitary cartridge of plastic material for discharging a pyrotechnic mixture, smoke flare, chaff round, and the like is disclosed. A slidable piston is contained within a hollow casing forming the cartridge to engage with a portion of the casing to provide an internal integral seal for sealing a replaceable impulse cartridge and/or blank plug therein. A moisture proof seal is thereby maintained when the cartridge is armed by the insertion of an impulse cartridge or downloaded by the insertion of a blank plug. To facilitate the assembly of the cartridge, a rupturable closed end is provided with an internal lip adapted for engagement with an end plug to facilitate its alignment and positioning therein.
