ABSTRACT:
A bottle cap having a cutting means located inside the cap for selectively opening a sealed bottle is described. The cap can be rotated in either direction over the seal to cause the seal to be punctured and to cause a "C"-shaped cut in the seal. In the preferred embodiment, the center of the "C"-shaped cut portion of the seal is dragged away from the center of the mouth of the bottle, and a portion of the linear remains uncut as the cap is rotated to prevent the liner from dropping down into the bottle.
