Definitions

  • the technical sector of the present invention is that of containers for ammunition, intended to ensure the transport thereof or their storage.
  • a plastic container has already been proposed for receiving ammunition with combustible casings.
  • document FR-A-2 477 698 proposes a container made of high pressure polyethylene containing a wedging means made of polyurethane. For this, we inject a polyurethane foam inside the container, we introduce the ammunition or an imprint adapted to the shape and dimensions of the ammunition and allowed to polymerize.
  • the object of the present invention is to propose a new type of container free of polyurethane intended to alleviate the aforementioned drawbacks, while providing improved damping of the ammunition with a lesser amount of material.
  • the invention therefore relates to a container for propellant charge with combustible casing, of the type consisting of an external envelope containing wedging means, characterized in that it comprises a bottom wedge in the form of a part. substantially cylindrical resting on the one hand on the bottom and on the other hand on the side wall of the casing, provided with a blind cylindrical recess adjusted substantially to the caliber of the load, a substantially cylindrical head block arranged in the vicinity of the open end of the container, and a spacer connecting the two wedges spaced from each other.
  • the spacer is in the form of a tube which is engaged in the recess of the bottom wedge and is made integral with the internal wall of the head wedge, for example by hooping.
  • the shims are parts molded by expansion of plastic material, of outside diameter substantially equal to the inside diameter of the envelope, and forced into it.
  • the shims are mechanically linked to the inside of the envelope by clamping and they have a height of approximately one gauge;
  • the tube forming the spacer can be made of kraft cardboard, and a cover of polyethylene / aluminum complex can be placed inside the tube.
  • a cover made of polyethylene / aluminum complex is introduced by hot compression into the spacer.
  • An advantage of the present invention lies in the simplicity of production of the container which only implements molding processes commonly used in the industry and which can be easily automated.
  • Another advantage of the invention lies in the reduction in the mass of the wedging means.
  • Yet another advantage of the invention lies in the choice of the material constituting the wedging means which is a recoverable or destructible material without toxic release, endowed with superior damping properties.
  • the container 10 comprises an envelope 1 obtained in a known manner by injection, the blind end of which delimits a bottom 4.
  • a handle 11 partially shown may be provided to facilitate handling.
  • the open end 6 of the envelope 1 can be closed by a plug 12 making it possible to perfect the setting of the load (not shown) contained in the envelope 1.
  • the load is positioned by a bottom wedge 2, a wedge of head 3 and a spacer for example, such as a tube 7.
  • the wedge 2 is a molded piece of polyethylene endowed with a certain deformability. It is in the form of a substantially cylindrical part, one end 13 of which is in contact with the bottom 4 of the casing 1. It is provided with a blind cylindrical recess 5 opening out at its other end.
  • the cylindrical wall 14 of the wedge has an external diameter adjusted to the internal diameter of the casing 1, so as to obtain a tight fit. This ensures calibration on three axes.
  • the wedge 3 is also in the form of a hollow cylindrical piece whose external diameter is substantially equal to the internal diameter of the casing 1 and whose internal diameter is slightly greater than the size of the load.
  • the wedge 3 is arranged in the vicinity of the open end 6 of the casing 1 and therefore ensures a wedging along two axes.
  • each shim can be delimited by providing for partial thinning 15 and 16 of the envelope 1.
  • the wedging means is completed by a tube 7 made of kraft cardboard and its role is to ensure surface continuity between the two wedges 2 and 3, and to fix their relative position.
  • the internal diameter of this tube is slightly greater than the caliber of the load, in order to facilitate the introduction of the latter.
  • the resistance of this tube is sufficient to absorb any shocks from the load which are passed on to the chocks.
  • the tube 7 is introduced hot into the envelope and made adhering to the shims by mechanical clamping.
  • a cover 8 can be provided inside the tube 7.
  • This cover 8 is conventionally made of polyethylene / aluminum, and opens in the vicinity of the plug 12. It is welded to the tube 7 and shaped on the head wedge by heating to perfect its inlet geometry.
  • the shims 2 and 3 are made of polyethylene foam with a density of the order of 20 to 30 g / l, retaining its damping properties at extreme temperatures of - 40 and + 70 ° C.
  • the weight gain is very significant compared to a polyurethane setting, of the order of 1.5 kg.
