Patent ID: 8522995

Claim:
A closure for opening and covering a sealed container comprising a pierce plate, a rotatable locking tab, a cap, a pivot, and a container skirt wherein said closure moves between a first closed position, an open position and a second closed position; wherein said pierce plate comprises an upper surface, a lower surface, a locking plate portion, a piercing portion, a rim lock portion, and an aperture wherein said piercing portion is juxtaposed to the lower surface, and comprises a channel that is aligned with said aperture to permit fluid to flow between the channel and the aperture; wherein the upper surface of said piercing plate sits on an inclined plane at an angle from the locking plate portion to the rim lock portion wherein said angle is determined by orienting the upper surface along a horizontal plane and angling the rim lock portion above the horizontal plane and the locking plate portion below the horizontal plane; wherein said rotatable locking tab comprises a cap connection portion and a toe portion, wherein said cap connection portion is juxtaposed to said cap and moves in response to movement of the cap, wherein said toe portion sits below the locking portion of the pierce plate and rotatably contacts to move said locking plate portion and the pierce plate when the cap and the cap connection portion move from the first closed position to the open position, wherein said toe portion moves substantially tangential to said locking plate portion of the pierce plate but does not substantially move said pierce plate when said cap moves from the open position to a second closed position wherein said cap comprises an aperture cover; wherein said container skirt comprises a rim stop and a container neck, wherein when pierce plate moves in response to the movement of said toe portion said rim lock portion engages said rim stop to substantially hold said pierce plate and to actuate the piercing portion; and wherein said container neck is adapted to mate with a container; wherein said pivot is juxtaposed to the lower surface of the pierce plate.
