ABSTRACT:
An expandable, externally-threaded collar member which is adapted to cooperate with an internally-threaded cap member to form a closure for a container. Advantageously, the expandable, externally-threaded collar member can be applied to the top, neck portion of the container by merely sliding said collar member over the rim of the container. Once in place, the container can then be sealed by applying the internally-threaded cap member to the externally-threaded collar member.
