ABSTRACT:
A method for forming at least one opening in a receptacle comprises the steps of providing a receptacle having a cover with an exterior surface and an interior surface covering a cavity. A cutting mechanism is also provided having at least one blade. The cover is pierced with the blade, and the blade is moved through the cover to cut a portion of the cover and create an opening in the cover to provide access into the cavity. Further, the cut portion curls on top of the exterior surface as the opening is created.
