Abstract:
One embodiment of the present invention provides a polymeric ammunition cartridge and methods of making and using the same. The cartridge includes a substantially cylindrical insert connected to a substantially cylindrical polymeric middle body. The substantially cylindrical insert includes a top surface opposite a bottom surface and a substantially cylindrical coupling element that extends from the bottom surface, a primer recess in the top surface that extends toward the bottom surface, a primer flash hole positioned in the primer recess to extend through the bottom surface, and a flange that extends circumferentially about an outer edge of the top surface. The substantially cylindrical polymeric middle body includes a substantially cylindrical polymeric bullet-end and a substantially cylindrical polymeric coupling end connected by a powder chamber, wherein the substantially cylindrical polymeric coupling end extends over the substantially cylindrical coupling element and covers a circumferential surface of the primer flash hole.

Claim (Index 1):
An ammunition cartridge having polymer casing and aninjection molded primer insert comprising:\n an injection molded primer insert for polymer ammunition comprising\n a top surface opposite a bottom surface, \n a substantially cylindrical coupling element extending away from the bottom surface forming an interior surface inside the substantially cylindrical coupling element, \n a primer recess in the top surface that extends toward the bottom surface, \n a primer flash aperture positioned in the primer recess to extend through the bottom surface, \n a flash hole groove positioned in the primer recess and extends around the primer flash aperture, and \n a flange that extends circumferentially about an outer edge of the top surface, wherein the flange is adapted to receive a polymer overmolding; \n a polymeric middle body molded over the injection molded primer insert to extend to a cylindrical middle body coupling region molded from a first polymer, wherein the first polymer is molded over the substantially cylindrical coupling element to the flange and into the primer flash aperture to the flash hole groove; a polymeric projectile end mated to the polymeric middle body, wherein the polymeric projectile end comprises a second polymer composition forming a projectile end coupling region that extends to a shoulder region that reduces to a neck region having a projectile aperture wherein the projectile end coupling region couples to the middle body coupling region; and a propellant chamber defined between the primer flash aperture and the projectile aperture.
