Abstract
A housing has a scored cylindrical casing that is designed to slidably fit into the barrel of a weapon and that is delimited by two side walls. After the casing breaks, due to the pressure of gases generated by a propellant charge, the housing is divided into at least two parts that are free to move relative to each other. Each housing part carries one casing element, ensuring gas tightness.
Claims23
A propellant charge housing for loading into a weapon barrel, the housing comprising:
- a cylindrical casing slidably fit within the barrel and having at least one annular score, the casing being of minimum thickness at the score and extending continuously across the score;
- and
- at least two side walls for delimiting the casing;
- wherein the propellant charge causes the casing to break, at the at least one annular score, into at least two casing parts so that the housing is divided into at least two housing elements that are freely movable relative to each other, each housing element comprising one of the at least two casing parts;
- and
- wherein the propellant charge urges each casing part against the barrel so that a gas-tight seal is established between each casing part and the barrel.

A propellant charge housing for loading into a weapon barrel, the housing comprising:
- two half-housings, each half-housing comprising a cylindrical casing slidably fit within the barrel, each casing having at least one annular score;
- and
- at least one side wall for delimiting the casing of each half-housing;
- wherein the propellant charge causes each casing to break, at the at least one annular score of each casing, into at least two casing parts so that the housing is divided into at least two housing elements that are freely movable relative to each other, each housing element comprising one of the at least two casing parts;
- and
- wherein the propellant charge urges each casing part against the barrel so that a gas-tight seal is established between each casing part and the barrel.

- a cylindrical casing slidably fit within the barrel and having at least one annular score;
- and
- at least two side walls for delimiting the casing, one of the side walls comprising a lid linked to the casing;

- and
- wherein the propellant charge urges each casing part against the barrel so that a gas-tight seal is established between each casing part and the barrel.
