Abstract: A closure device for a plastic container includes a liner and a plastic closure. The liner is sealed to the neck of the bottle at the end face of the neck and along a portion of the outer surface of the neck. The plastic closure engages the liner to retain the liner against the neck during sealing and to seal the area between the liner and the closure top from liquids present during cooling of the container. The closure includes a top wall, an annular closure skirt depending from the top wall, an annular outer flexible seal depending from the top wall, and at least one annular pressure ring. The outer flexible seal retains an outer edge of the liner against the outer surface of the container neck and prevents ingress of liquids. The annular pressure ring engages the liner to retain the liner against the end face of the neck during sealing.

Abstract: A container which includes body, neck and cover portions of one-piece plastic construction and a line of weakness defined between the neck and cover portions to permit selective separation of the cover from the neck, further includes an inner closure carried by and removable with the cover portion to prevent spillage of the container contents upon opening of the container. The inner closure is disposed to seal the neck below the line of weakness to isolate the contents of the container from the area of the line of weakness. When the container is heat sterilized, means is provided associated with the chamber defined by the cover and closure to prevent collapse of the cover during the post heat-sterilization cooling cycle. The associated means includes structure to provide moist air in the defined chamber during heating of the container without endangering the sterility of the container contents or nullifying the advantage of the inner closure.
