ABSTRACT:
A pressure relief vent on a container includes a flat diaphragm fastened to the exterior of a container so as to cover an opening in the container. The diaphragm is fastened to the container at its perimeter and at at least one point within its perimeter. The shape of the peripheral fastening seam and the number of and size of the point fastenings determine and stabilize the vent pressure at which the diaphragm ruptures.
