Abstract

A cartridge is made up of a synthetic resin case member and a synthetic resin lid. The case member contains a first receiving chamber for receiving an igniter charge and a second receiving chamber for the accommodation of a propellant charge. A synthetic resin ignition pin flexibly connected to the lid extends into the first receiving chamber. Upon the exertion of pressure by a striker on the rear end of the ignition pin, the pin is advanced further into the first receiving chamber, a pointed forward percussion end of this ignition pin acting on the igniter charge to ignite the charge. The igniter charge is accommodated in funnel shape in a conical depression of the first receiving chamber. The percussion end of the ignition pin, extending into the igniter charge, upon displacement, causes friction in the igniter charge material and thus generates frictional heat therein. Owing to this "broaching-type igniter principle", it is possible to obtain a reliable ignition of the igniter charge in spite of the use of synthetic resin, substantially softer as compared with metal, as the material forming the case member and forming the ignition pin.
