one
The invention relates to sleeves for hunting cartridges, and more specifically to plastic collection sleeves.
Known plastic pre-assembled sleeve containing a tubular casing with stepped flange and a bottom with an inner conical surface and a socket under the primer-igniter cap.
The disadvantage of this sleeve is reduced shot resistance. This is due to the fact that in the manufacture of a plastic bottom of a large thickness by injection molding, various defects are formed, which lead to the destruction of the sleeve when exposed to it powder gases during a shot.
The purpose of the invention is to increase the strength of the liner when fired.
This goal is achieved by the fact that the bottom of the sleeve is made of the outer part adjacent to the body of the sleeve and forming the base 25 of the sleeve with the slot under the primer-igniter, and the inner part, the front section of which is beveled inward and recessed into the counter groove on the conical surface of the bottom part .
The case is presented in the shell, a longitudinal section.
The sleeve has a plastic tubular body 1 step with a flange 2 and the bottom, consisting of two parts: the outer 3, made of plastic, and the inner 4, made of plastic or any other matter. The back part 3, on the one hand, is associated with the body 1 and forms the base 5 of the sleeve with the nest 6 under the primer cap, and on the other hand covers the inner part 4. Front section 7 of the inner part 4 is bevelled inward and recessed into the counter groove on the conical surface 8 outside part 3.
The proposed implementation of the liner allows reducing the thickness of the plastic parts, eliminating possible casting defects and thereby increasing the liner strength when fired.
