ABSTRACT:
A multiple-dome, scored rupture disc presents opposing first and second disc faces, and is provided with a circular, central region and a flat annular flange surrounding the central region. An arcuate line of weakness is formed in the disc circumscribing the central area except for a portion of the circumference of the central area defining a hinge about which the central region pivots upon rupture. The central region is divided by a diametrical ridge into two side-by-side semicircular halves within which the disc is bulged to form a plurality of separate concavo-convex bulges in the body.
