a high-pressure air canister in the space; a cap including two front through holes, external threads adjacent to the through holes, an internal primer between the through holes, and at least one spacer between the primer and the air canister wherein the cap is in the sleeve with the external threads and the internal threads secured together; and a first washer sandwiched by and between the cap and the inner surface of the space. ## Claims ### Claim 1 A cartridge comprising: a housing disposed in a launching device and including an internal space, a piercing member disposed on a rear end of the internal space, a channel through the piercing member to communicate the internal space with at least one projectile, a metal sleeve disposed at a front end of the space, at least one annular ridge formed on an outer surface of the sleeve, and internal threads formed on an inner surface of the metal sleeve wherein the sleeve and the piercing member are formed integrally in the housing in an injection molding; a high-pressure air canister disposed in the internal space and proximate the piercing member; a cap including two front through holes, external threads adjacent to the front through holes, an internal primer disposed between the front through holes, at least one spacer disposed between the primer and the air canister, and an annular projection disposed on an end of the internal space and configured to complimentarily secure to the piercing member wherein the cap is disposed in the sleeve with the external threads and the internal threads secured together; and a first washer sandwiched by and between the cap and the inner surface of the internal space. ### Claim 2 The cartridge of claim. 1, wherein the number of the at least one projectile is two, the projectiles disposed in two tunnels above and under the internal space respectively, and each of the projectiles including a dart, and wherein one dart is electrically conducive and has a positive electrode and the other dart is electrically conductive and has a negative electrode. ### Claim 3 (depends on 1) The cartridge of claim 1, wherein one of the projectile is disposed in a front chamber, and wherein one of the projectiles is a Capsicum annuum ball or pepper ball. ### Claim 4 (depends on 3) The cartridge of claim 3, further comprising a second washer sandwiched by and between the chamber and a front end of the housing. ### Claim 5 (depends on 1) The cartridge of claim 1, wherein the metal sleeve is made of copper or steel. ### Claim 6 (depends on 1) The cartridge of claim 1, wherein the launching device is attached to a non-lethal weapon. ### Claim 7 (depends on 6) The cartridge of claim 6, wherein the non-lethal weapon includes a light, a butt, and a trigger.
