Abstract: A container assembly for providing a sterile sealed container including a container having a neck provided with an annular mouth defining bead and a multipiece closure having a sealing member, a locking member and a cover secured thereto. The mouth defining bead has an upper surface, an exteriorly disposed downwardly and inwardly inclined closure anchoring shoulder defining surface and an outer surface connecting the upper surface with the shoulder defining surface. The locking member has a top panel with an opening therein and a depending skirt which has a lower surface radially inwardly deformed into locking engagement with the anchoring shoulder. At least two radially outstruck lugs formed within the locking member skirt. A portion of the sealing member compressively secured between the locking member and the container neck. The cover having a top panel and a skirt having a lower portion deformed radially inwardly to a diameter less than the diameter of the locking member taken at the position of at least one outstruck lug. At least one radially inwardly directed embossment formed in the cover skirt at a height generally the same as the lugs. Rotation of the cover with respect to the locking member causes the embossment to permanently inwardly reform the outstruck lugs and permit relative axial separation of the closure and locking member.

Abstract: A sheet metal container closure is provided which has a top panel and a depending skirt for affixation to a container and a sealing liner of resilient deformable material underlying the top panel of the closure for sealing against a sealing surface of the container, and further having a score line centrally located in the top panel of the closure, which score line is rupturable by excessive pressure in a container on which the closure is sealed to provide an aperture in the top panel of the closure through which a portion of the sealing liner can be forced to permit gas to escape from the container between the sealing liner and the sealing surface of the container.
