Abstract
A receptacle for the propelling charge for large caliber gun ammunition is combustible, and includes a barrel-protection coating which is applied directly to the interior surface of the receptacle. The coating is composed of a mixture of wax and titanium dioxide. In order to prevent the propelling charge powder in the receptacle from directly contacting the coating, the coating is covered with a thin metal foil, such as a thin lead foil.

A propelling charge receptacle for use with large-caliber gun ammunition, comprising:
- a combustible receptacle which includes a propelling charge container having an upper shell with a shell top and with a generally cylindrical wall portion and having a lower shell with a shell bottom and with a generally cylindrical wall portion, the wall portions of the upper and lower shells being connected at a junction region, the wall portions having interior surfaces;
- and
- a coating of wax and titanium dioxide which is directly applied to the interior surfaces of the wall portions of the upper and lower shells.
A propelling charge receptable for use with large-caliber gun ammunition, comprising:
- a combustible receptacle which includes a propelling charge casing having a combustible cover with a conical interior surface and having a cylindrical casing with an interior surface;
- a coating of wax and titanium dioxide which is applied directly to the conical interior surface of the cover and to at least individual regions of the interior surface of the cylindrical casing;
- and
- a non-combustible stub casing for armor piercing ammunition, the stub casing being connected to the cylindrical casing.
A propelling charge receptacle for use with large-caliber gun ammunition, comprising:
- a combustible receptacle which is to be filled with propelling charge agent, the receptacle having an interior surface;
- a coating of wax and titanium dioxide directly applied to the interior surface of the receptacle;
- and
- a thin metal foil covering the coating of wax and titanium dioxide.
A method for making a propelling charge container which includes a combustible upper shell with a shell top and a generally cylindrical wall portion, and a combustible lower shell with a shell bottom and a generally cylindrical wall portion, the wall portions of the upper and lower shells having interior surfaces, said method comprising the steps of:
- (a) applying a coating of wax and titanium dioxide to the interior surface of the wall portion of the upper shell and to the interior surface of the wall portion of the lower shell;
- (b) covering the coatings on the interior surfaces of the wall portions with thin metal foil;
- (c) fastening the wall portions of the upper and lower shells at a junction region;
- (d) introducing a propelling charge agent into the shells through a fill opening;
- and
- (e) closing the fill opening with a sealing cover.
