(54) Container lid


(57) A container lid comprises a metallic screw member (1) detachably fitted onto a container mouth (3), a metallic outer cap (13) fitted around the screw member, and a metallic packing member (7) secured above an open top of the screw member and below a closed top of the outer cap to provide elastic deformation when the lid is fitted onto the container mouth. In a preferred embodiment, the packing member is made hollow to provide an internal closed air chamber (10) which acts as an air cushion or air spring when the container is lidded. The underside of the packing member is preferably covered with a resin layer (9) or metal oxide layer or aluminum foil (7g).
