ABSTRACT:
On the inside of a cylindrical envelope, an anvil projects from the base of the envelope and has a flat central member extending parallel to an axial plane of the envelope. Flash-holes are formed in the flat areas of the base on either side of the central member so as to create passages in the vicinity of the axial plane of the cylindrical envelope. The central member has two extensions which have a tapered upper portion and connect to the top of the flat central member, forming a relatively flat end, the lower part of the anvil being connected to the cylindrical envelope, forming an integral part of it.
