Abstract
A sanitary rupture disk apparatus includes a rupture disk member having a periphery and a stitched portion, preferably positioned next to the periphery. A hinge area that is unstitched is provided also at the periphery of the rupture disk member. A peripheral holder or support engages the periphery of the disk member, the peripheral support being comprised of a pair of backup rings and a flexible, preferably polymeric member. The polymeric member can be in the form of a two-part flexible sanitary gasket. A pair of annular flanges of the flexible gasket extend radially inwardly of the peripheral support, each of the flanges overlapping and sealing the stitched portion of the disk member, the flanges enabling a pressure loading of the disk member.
