Abstract

The invention relates to a cartridge having a propellant charge casing at least partially filled with a propellant charge powder, and a projectile part connected on a front of the propellant charge casing, wherein the propellant charge casing comprises a casing cover, a casing sheath and a casing base, and the casing sheath is connected to the projectile part via the casing cover and to the casing base via a spring steel sheet. In order to achieve different amounts of propellant charge powder filled into the same propellant charge casing without igniting the propellant charge at undesirable blast waves, a sack-shaped container that is completely filled with the respective amount of propellant charge powder is disposed inside the propellant charge casing so that the container, and thus also the propellant charge powder, extends in the direction of the central longitudinal axis of the cartridge.

Claims

1. A cartridge having:

(a) a propellant charge casing that is at least partially filled with propellant charge powder; and

(b) a projectile part connected to the propellant charge casing at a front end of the propellant charge casing, wherein the propellant charge casing has

i. a casing cover;

ii. a casing sheath; and

iii. a casing base, wherein the casing sheath is connected on one end via the casing cover to the projectile part and the casing sheath is connected on another end via a spring plate to the casing base, and

the propellant charge powder is arranged in a container that is in the form of a sack and extends in a direction of a longitudinal axis of the cartridge.

2. The cartridge as claimed in claim 1, wherein a first end area located at a base end of the container is attached to the casing base by a spring plate, and a second end area located at a projectile end of the container is connected to a composition aid that is arranged transversely with respect to the longitudinal axis of the cartridge, and an edge area of the composition aid is flat, and is connected in a force-fitting manner, or in an interlocking manner, or in a force-fitting and interlocking manner, at a junction area to the casing sheath, or to the casing cover, or to the casing sheath and the casing cover.

3. The cartridge as claimed in claim 2, wherein the composition aid is in the form of a cap and has a hemispherical outward bulge that extends in a direction of the projectile part, and a flat edge area of the composition aid surrounds the outward bulge, wherein an internal diameter of the outward bulge corresponds to an internal diameter of the container.

4. The cartridge as claimed in claim 3, wherein the composition aid has at least two opposite recesses formed therein in the form of slots in the junction area between the outward bulge and the flat edge area, wherein through the recesses two front areas of the second end area of the container pass, wherein the two front areas are in the form of tabs and are axially separated from one another at the projectile end of the container, and the two front areas are connected in an force-fitting manner at a front end of the compositional aid to the outward bulge.

5. The cartridge as claimed in claim 4, wherein the two front areas of the container are knotted to one another.

6. The cartridge as claimed in claim 3, wherein the two front areas are adhesively bonded to the outward bulge on the composition aid.

7. The cartridge as claimed in claim 2, wherein the composition aid is made of a plastic, and the plastic is a sprayable plastic.

8. The cartridge as claimed in claim 2, wherein the end attachment of the composition aid is provided in the junction area between the casing sheath and the casing cover.

9. The cartridge as claimed in claim 1, wherein the container comprises cotton fabric.
