CA 2043508

ABSTRACT A self-closing membrane closure that is an integral part of the shoulder of a tube container provides for an efficient method for packaging and dispensing paste-like products. The self-closing membrane is formed at the same time as the supporting shoulder by compression molding or a related technique. This negates the need for any assembly and the potential for leakage. In addition to the self-closing membrane closure, there can also be cap fitted over the membrane closure. ?
