Reloadable non-lethal training cartridge
View Patent ↗A reloadable non-lethal training cartridge is provided comprising a cartridge case, a rear high pressure chamber removably disposed within the base thereof, and a non-lethal payload portion removably disposed adjacent the forward end of the cartridge case. The rear high pressure chamber is provided with a base capable of interacting with a removal tool, such as a hexagonal shaped base capable of interacting with a standard socket. Further, the non-lethal payload portion is comprised of a base and a non-lethal payload, the non-lethal payload and base being removably attached such that one or both of said components may be reused. In addition, the non-lethal payload may be weighted, so as to increase the accuracy thereof.

(b) a circumferential portion adjacent said base defining an exterior portion and an interior portion, said interior portion defining a low pressure chamber; and
(b) a forward end adjacent said circumferential portion,
ii. a rear high pressure chamber removably disposed within the base threaded aperture of the cartridge case, said rear high pressure chamber having:
(c) a base comprising an outer circumference capable of engagement with a removal tool, an inner portion, and a firing blank insertion aperture formed through said inner portion;
(d) a circumferential portion adjacent said base, said circumferential portion comprising an exterior portion having threads formed thereon, and an interior portion defining an interior firing blank containment portion; and
(e) a forward end adjacent said circumferential portion, said forward end having a propellant vent hole formed therethrough, said propellant vent hole having an outer circumference,
iii. a non-lethal payload portion removably disposed adjacent the forward end of said cartridge case, said non-lethal payload portion having:
(f) a base comprising a rear face, a rear edge adjacent the rear face having a frictional engagement means capable of frictional engagement with the forward end of said cartridge case, and a circumferential portion adjacent the rear edge having a non-lethal payload engagement portion; and
(g) a non-lethal payload disposed adjacent the non-lethal payload engagement means of said base,
wherein the high pressure chamber may be threadably removed from the cartridge case after firing of the reloadable non-lethal training cartridge.
2. The reloadable non-lethal training cartridge of claim 1 , wherein the high pressure chamber further comprises an o-ring disposed around the circumferential portion and adjacent the base, so as to contact the cartridge case base threaded aperture and the high pressure chamber base and thereby create a seal.
3. The reloadable non-lethal training cartridge of claim 1 , wherein the cartridge case is comprised of a plastic or polymeric material.
4. The reloadable non-lethal training cartridge of claim 1 , wherein the cartridge case is comprised of a metallic material.
5. The reloadable non-lethal training cartridge of claim 1 , wherein the non-lethal payload engagement means and the non-lethal payload of the non-lethal payload portion are removably engaged.
6. The reloadable non-lethal training cartridge of claim 1 , wherein the non-lethal payload engagement means and the non-lethal payload of the non-lethal payload portion are fixedly engaged.
7. The reloadable non-lethal training cartridge of claim 5 , wherein the non-lethal payload engagement means is comprised of a threaded portion, an interlocking means, or a frictional engagement means.
8. The reloadable non-lethal training cartridge of claim 7 , wherein the non-lethal payload comprises an engagement portion and a payload portion, said engagement portion capable of removable engagement with the non-lethal payload engagement means of the non-lethal payload portion.
9. The reloadable non-lethal training cartridge of claim 8 , wherein the non-lethal payload portion is comprised of a hollow or solid foam head, a hollow or solid rubber head, a hollow or solid plastic head, or a hollow or solid head comprised of a combination of foam, rubber or plastic.
10. The reloadable non-lethal training cartridge of claim 8 , wherein the non-lethal payload portion further comprises weighted material disposed within the hollow head.
11. The reloadable non-lethal training cartridge of claim 1 , wherein the high pressure chamber further comprises a washer removably disposed within the interior portion adjacent the forward end of the high pressure chamber, said washer having an aperture formed therethrough, said aperture having a diameter smaller than a diameter of the propellant vent hole formed in the forward end of the high pressure chamber.
12. The reloadable non-lethal training cartridge of claim 1 , wherein the threads formed on the circumferential portion of the high pressure chamber are double threads.
13. The reloadable non-lethal training cartridge of claim 1 , wherein the threads formed on the circumferential portion of the high pressure chamber are single threads.
14. The reloadable non-lethal training cartridge of claim 1 , wherein the circumference of the base of the rear high pressure chamber is square, pentagonal, hexagonal or octagonal in shape.
15. A reloadable cartridge comprising:
i. a cartridge case having:
(a) a base comprising an exterior portion, an interior portion, and a base threaded aperture formed within said base from the exterior portion;
(b) a circumferential portion adjacent said base defining an exterior portion and an interior portion, said interior portion defining a low pressure chamber; and
(b) a forward end adjacent said circumferential portion,
ii. a rear high pressure chamber having:
(c) a base comprising an outer circumference having a non-circular shape so as to allow engagement with a removal tool, an inner portion, and a firing blank insertion aperture formed through said inner portion;
(d) a circumferential portion adjacent said base, said circumferential portion comprising an exterior portion having threads formed thereon, and an interior portion defining an interior blank containment portion; and
(e) a forward end adjacent said circumferential portion, said forward end having a propellant vent hole formed therethrough,
iii. a payload portion removably disposed adjacent the forward end of said cartridge case, said payload portion having:
(f) a base comprising a rear face, a rear edge adjacent the rear face having a frictional engagement means capable of frictional engagement with the forward end of said cartridge case, and a circumferential portion adjacent the rear edge having a payload engagement portion; and
(g) a payload disposed adjacent the non-lethal payload engagement means of said base,
wherein the high pressure chamber may be threadably removed from the cartridge case after firing of the reloadable non-lethal training cartridge, and the payload portion may be removed and replaced after firing.
16. The reloadable non-lethal training cartridge of claim 1 , wherein the non-lethal payload portion further comprises a rotating band disposed around the circumferential portion of the base, said rotating band capable of interacting with a barrel rifling groove.
