1. A closing and opening device for a bottle with an opening sealed by a membrane, comprising:
- a cap adapted to engage the opening of the bottle for closing the same,means for cutting the membrane of the bottle without pushing the membrane downwardly while cutting, said cutting means being connected to the cap, andmeans for allowing rotation of the cap less than 360 degrees relative to the opening of the bottle, said means for allowing rotation being connected to the cap so that while the cap is rotating, the membrane of the bottle is cut less than 360 degrees without pushing the membrane downwardly to prevent the membrane being cut from detaching from and entering into the bottle.

6. A closing and opening device for a bottle with an opening sealed by a membrane, comprising:
-
a cap adapted to engage the opening of the bottle for closing the same, said cap including a head, a first circular wall integrally connected to the head, and a first female thread formed at the inner periphery of the first circular wall adapted to engage a male thread of the bottle, means for cutting the membrane of the bottle, said cutting means being connected to the cap, and means for allowing rotation of the cap less than 360 degrees relative to the opening of the bottle, said means for allowing rotation including a second circular wall connected to the cap to define a mouth therearound and extending from the head in the direction opposite to the first circular wall, and a second female thread formed at the inner periphery of the second circular wall to extend less than 360 degrees so that when the second female thread is engaged with the male thread of the bottle and the cap is rotated, the membrane of the bottle is cut less than 360 degrees to prevent the membrane being cut from detaching from the bottle. - View Dependent Claims (7, 8, 9, 10, 11)
