Abstract
A wine closure replaces the traditional cork and foil and includes a gasket/stopper which engages into the neck of the bottle. Encasing the finish and upper neck of the bottle is a plastic outer closure cap, generally cylindrical, with a top center disc which is adhered to the top of the stopper. A circle of frangible elements at the periphery of the disc provide for breakage of the disc away from the sleeve, causing it to remain with the stopper when the plastic cap is opened. Coarse, shortlength threads are formed on the outside of the container neck, spaced appreciably below the finish, to be engaged by internal thread lugs of the plastic cap. On initial unscrewing of the cap, the disc breaks away from the remainder of the cap. A small vertical clearance is provided in the engagement between the internal cap structure and the gasket/stopper, so that the cap does not begin to lift the gasket/stopper until static friction against the elastomeric gasket/stopper has been overcome.
