Abstract
A container closure having a multiple liner seal is disclosed. The closure comprises a plastic closure cap having a circular top wall portion and a depending annular skirt portion. The skirt portion has an internal thread formation for threadedly engaging a cooperative container. In a typical closure, a pilfer band depends from the skirt portion. The closure cap has an abutment internal thereto, generally at the juncture of the top wall portion and the skirt portion. A first resilient, molded-in plastic seal is positioned in the cap adjacent to and against the top wall portion, and a second resilient plastic seal is positioned in the closure and extends thereacross resting upon the abutment. When the closure is threadedly engaged with a container, the second seal provides a top/side seal to seal the contents from the environs. The closure will seal a container with or without the second seal in place because of the independent sealing capabilities of the first seal.
