ABSTRACT:
A cartridge (24) for explosively operated industrial tools is disclosed. The tool (10) is of the type that has a piercer pin (46) that pierces through a surface of the cartridge during assembly of the cartridge within the tool. Then, upon firing of the cartridge, the residual gases (72) formed by the explosion are vented to the atmosphere by moving the piercer pin out of the pierced opening (70). The present cartridge includes a depression (64) in a surface of the base (62) that is in alignment with the piercer pin. There is a relatively thin section (66) of the base left at the bottom of the depression. The thin section is sized so that when it is unsupported, as for example when a defective piercer pin is used, it will fracture under the forces of the exploding powder (38) and the residual gases formed by the explosion will be vented through the fracture and into the atmosphere.
