ABSTRACT:
An interference threaded closure assembly includes a container and a cap. The container has a neck portion extending therefrom, the neck portion forming an opening and having on an outer surface screw threads and at least one interference bead on the screw threads. The cap has on an inner surface screw threads and a seal for releasably engaging the opening of the neck portion to form a leak free seal. The interference bead of the screw threads engages the screw threads of the cap to create an interference fit when the screw threads are threadably engaged, thereby maintaining the leak free seal of the seal within the opening.
