Abstract
A multiple-domed, scored rupture disc (28) having a non-apertured disc body (62) provided with separate, side-by-side, semi-circular concavo-convex bulges (76) and an arcuate line of weakness (68) circumscribing the bulges is provided with a diametrical ridge (74) extending across and serving as a divider between the bulged areas of the disc body. The distance between the outer margin of the ridge and a plane through the annular planar section of the disc body is from about 0.3% to about 3% of the diameter of the bulged area to increase the rigidity of the divider ridge. The greater rigidity of the divider ridge decreases the burst pressure of the disc.
