ABSTRACT:
A closure fitting is provided for a container which itself has no threads or other closure securing means formed on it. The fitting, which can be pressed down over the mouth of a container, provides its own securing means by which an outer, closure portion of the fitting can be removed from and resecured to an inner attachment portion which remains on the container after opening. The closure fitting may have a stretchable or distendable conical hoop molded inside a surrounding skirt. Cooperating sets of threads, lugs, or the like are formed on the outer face of the conical hoop and on the inner face of the skirt. In the closure as formed, the closure securing means of the hoop do not operably engage those of the skirt. They are progressively brought into cooperating engagement by stretching and enlarging the hoop outwardly as the closure fitting is press-fitted onto a container. The hoop is severably joined to the skirt; twisting or otherwise removing the skirt from the hoop in the first opening breaks the connections of the hoop to the skirt, so that the closure can be removed from the hoop. The closure can thereafter be used in the same manner as a conventional closure.
