ABSTRACT:
An inverting, rupturable, pressure relieving apparatus includes a structure having a wall for containing pressurized fluid and an asymmetrical indentation in the wall. The indentation has a base connecting the indentation to the wall, a protuberant side for contacting the pressurized fluid, a recessed side opposite the protuberant side, and an axis about perpendicular to the base and extending through the center of the indentation at the base. The asymmetry of the indentation creates an inversion initiation face in the indentation having a smaller angle with the base and less resistance to inversion than the remainder of the indentation.
