ABSTRACT:
A closure with internal security for bottles and the like is described, which allows the contents to be immediately and freely poured from the bottle as soon as it is taken from a refrigerator, and therefore has a partial vacuum within it. This closure includes a body which is fixed to the mouth of the bottle and defines a fluid passage, a cap which can be screwed onto the body to close the passage, at least one valve shutter movable along the passage in the body to engage a valve seat in the passage, engagement means between the shutter and the cap for turning of the shutter by the cap as it is unscrewed, a cusp-shaped projection on the body facing the shutter, and a corresponding projection on the shutter for engaging and riding over the cusp-shaped projection upon unscrewing of the cap, to raise the shutter from the valve seat.
