  • Patent number: 7422102
    Abstract: A container for an ammunition cartridge having a conical forward portion includes a generally cylindrical cap having a closed end and an open end; a generally cylindrical main body having a closed end, an open end and a wall, a thickness of the wall at the open end decreasing from a larger thickness to a smaller thickness to form a taper on an exterior surface of the wall; a latch assembly disposed in part on the cap and in part on the main body to lock the cap and the main body in position; a first gasket disposed in the cap; a second gasket disposed around the taper of the main body; a cartridge support disposed inside the main body; a pair of bosses disposed on the main body and axially separated; and a strap connecting the bosses and comprising a middle portion and two end portions, whereby when a load is applied to the middle portion the end portions are forced against the bosses.

  • Patent number: 7121401
    Abstract: A packaging system for a single ammunition includes a cylindrical metal container and a cap therefore. A locking mechanism locks the cap to the top end of the container and a guiding mechanism guides the cap onto the top end of the container before the locking mechanism is locked to assure proper alignment. A plurality of impact rings are located laterally about the container and the cap to provide impact protection therefore. A stacking mechanism for each container allows a plurality of the containers to be securely stacked adjacent one another. The stacking mechanism includes a first top member and a second top member located adjacent the top ring and located 180° from one another about the cap such that the first top member of one cap interlocks with the second top member of an adjacent cap, and a similar arrangement on the bottom ring of the container.

  • Patent number: 6772877
    Abstract: A composite monopack container for mortar ammunition is lightweight, universally adaptable to all existing ammunition types, is capable of fully protecting ammunition without the need of a metal overpack, and is relatively inexpensive to produce, maintain and dispose. The container is also fully back-compatible enables a quicker ammunition re-supply and greater ammunition availability on the battlefield. The monopack container comprises a cap, a main body, a latch assembly that locks the cap and the main body, a pair of alignment features that mate with two corresponding alignment channels on the main body, and three stacking indices that prevent the container from rolling, and that make it stackable with other composite containers.

  • Patent number: 6460694
    Abstract: A container that is a spirally-wound, laminated, and cylindrically shaped is capable of protecting a mortar or other round from a large number of environmental conditions. The laminate material includes a layer of low-density polyethylene (LDPE) heat-bonded to a kraft paper, and is both durable, strong, and moisture-resistant. During the container manufacturing process, multiple layers of the laminate material, augmented by one or more layers of aluminum foil, are wound in a spiral fashion over an interior cylinder of ammunition container board, using conventional tooling and machinery. Layers of the cylinder are bonded to their contiguous neighbors by adhesive. The ends of the containers are sealed with crimped metal end caps, effecting a durable and moisture-resistance seal and giving the cylinder added crush-resistance. The construction of the container requires no high temperature operations, produces no noxious fumes, and does not expose workers to hazardous or toxic materials.
