(54) Pasteurizable container closure


(57) A closure for bottles (10) is disclosed which includes an internal radius support disc (48) or cylinder (58) for positioning within the mouth (12) of the bottle to enable the bottle to resist radial inward deformation when subjected to pasteurisation or other post-bottling heat treatment. The closure (40) can be formed by coining a conventional aluminium roll-on cap blank using a pressure block (60) having a central land (64) projectable into the mouth of the bottle to form the support disc or cylinder from the top of the cap blank. Also the cap (50) can be moulded thereby providing a moulded cylinder (58).
