ABSTRACT:
A reusable closure for containers having an opening in a surface thereof. A seal of size and shape sufficient to cover the opening in the container and having a bore therethrough is positioned such that the bore generally is aligned with a portion of the opening including opposed edges thereof. A threaded cap has a diameter less than that of the bore, whereby threaded engagement between the cap and opposed edges of the opening is achieved. Tightening the cap holds the seal firmly in place, thereby maintaining a positive closure of the opening. The seal may abut a lip of the container thereby restricting lateral movement of the cap. The seal and the threaded cap may be separate elements or of integral construction. The invention is particularly suited for use in containers having a convenience opening known as pop-top cans.
