Abstract

A cartridge casing body for an ammunition article has a first end and a second end; an attachment device at the first end, the attachment device being adapted to secure a projectile to the first end of the cartridge casing body; the cartridge casing body further including an internal volume for holding a propellant, wherein the internal volume is open at the first end of the cartridge casing body such that the internal volume is adapted to be closed at the first end by the projectile when the projectile is attached to the cartridge casing body; and the second end of the casing body includes an ignition device; wherein the cartridge casing body is made from plastic, ceramic, or a composite material.

Claims

1. A cartridge casing body for an ammunition article, the casing body comprising:

a first end and a second end;

an attachment device at the first end, the attachment device being adapted to secure a projectile to the first end of the cartridge casing body;

the cartridge casing body further including an internal volume for holding a propellant, wherein the internal volume is open at the first end of the cartridge casing body such that the internal volume is adapted to be closed at the first end by the projectile when the projectile is attached to the cartridge casing body; and

the second end of the casing body includes an ignition device;

wherein the cartridge casing body is made from plastic, ceramic, or a composite material.

2. The cartridge casing body of claim 1, wherein the cartridge casing body is made from plastic.

3. The cartridge casing body of claim 1, wherein the cartridge casing body is made from ceramic.

4. The cartridge casing body of claim 1, wherein the cartridge casing body is made from a composite material.

5. The cartridge casing body of claim 1, wherein the attachment device includes circumferential flange arranged around the inside of the first end of the casing body.

6. The cartridge casing body of claim 1, wherein the attachment device includes a plurality of flanges arranged around the inside of the first end of the casing body.

7. The cartridge casing body of claim 2, wherein the attachment device includes circumferential flange arranged around the inside of the first end of the casing body.

8. The cartridge casing body of claim 2, wherein the attachment device includes a plurality of flanges arranged around the inside of the first end of the casing body.

9. A cartridge casing body for an ammunition article, the casing body comprising:

a first end and a second end;

attachment means at the first end, the attachment means being adapted to secure a projectile to the first end of the casing body;

the casing body further including an internal volume for holding a propellant, wherein the internal volume is open at the first end of the casing body such that the internal volume is adapted to be closed at the first end by the projectile when the projectile is attached to the casing body; and

the second end of the casing body includes an ignition device;

wherein the cartridge casing body is made from plastic, ceramic, or a composite material.

10. The cartridge casing body of claim 9, wherein the cartridge casing body is made from plastic.

11. The cartridge casing body of claim 9, wherein the cartridge casing body is made from ceramic.

12. The cartridge casing body of claim 9, wherein the cartridge casing body is made from a composite material.

13. The cartridge casing body of claim 10, wherein the attachment means includes circumferential flange arranged around the inside of the first end of the casing body.

14. An ammunition article, comprising:

a cartridge casing body having a first end and a second end;

an attachment device at the first end;

a projectile secured to the first end of the casing body with the attachment device;

the cartridge casing body further including an internal volume for holding a propellant;

a propellant in the internal volume;

wherein the internal volume is closed at the first end of the cartridge casing body by the projectile; and

the second end of the cartridge casing body includes an ignition device;

wherein the cartridge casing body is made from plastic, ceramic, or a composite material.

15. The ammunition article of claim 14, wherein the cartridge casing body is made from plastic.
