ABSTRACT:
A threaded blade holder for cutting an opening in a flexible externally threaded closure element on a pail or container. The holder comprises a hollow internally threaded tubular body. A retaining member, comprising a pointed spike, is slideably disposed in a central aperture in the top of the tubular body to perforate the closure element and to relieve internal pressure in the pail through space between loosely fitting threads on the blade holder and the closure element. A pointed cutting blade, having a single cutting edge, extends downwardly from the top of the tubular body such that rotation of the tubular body onto the externally threaded closure element of the pail causes the blade to engage the upper surface of the closure element to cut a circular hole therein. However, the blade does not cut into material adjacent the periphery of the hole when the tubular element is removed from the externally threaded closure element. The retaining member, extending through the circular diaphragm portion of the closure element that has been cut out of the end of the closure element, prevents contamination of contents of the pail since the severed diaphragm is retained inside the tubular body.
