Title:
非貫入型発射体
Document Type and Number:
Japanese Patent JP2004505230
Kind Code:
A
Abstract:
A non-lethal projectile or a projectile for delivery of a substance has a casing 1 which surrounds a compartment 2 for containment of the substance 3. A hollow tube 5 projects forward within an ogival nose cap 8. An inflatable membrane 7 is located within the nose cap 8. The rear end of the compartment 2 has a piston 4 the rear side of which communicates through passageway 14, valve 12 and orifice 11 with the rear end of the projectile whereby propulsive gases on firing are stored in the cavity 15 to the rear of the piston. The nose cap 8 is of a readily breakable plastics material. On target impact the nose is displaced and permits a small amount of substance from compartment 2 to bleed through opening 6 allowing piston 4 to move forward uncovering ports 16. This action allows pressure gas to pass through the ports 16 and ducts to inflate the membrane 7 to spread the impact over a wide area. The piston is also free to move forward to discharge the substance through needle 5. In another construction (Fig. 6) a membrane 33 forms the nose of a non-lethal bullet and contains a gel 36. On impact the gel moves valve plate 38 back to allow pressure gas in casing 30 to act through ports 40 to inflate the membrane 33.
