Abstract
Abstract A closure for use on a container neck may be constructed including a top adapted to be located over the end of the neck, a sealing structure serving as a cork or stopper for engaging the interior of the neck located on the top so as to depend from it and a dependent skirt located at the periphery of the top so as to fit over and extend around the exterior of the neck. The skirt includes a fixed portion and a tear-off portion separated from the remainder of the closure by a severable means such as a line of reduced thickness, perforations or both. A tab is located on the fixed portion. With this structure the tear-off portion of the skirt may be removed from the closure so that the tab and fixed portion may thereafter be used as a handle in removing and replacing the closure upon a container neck.
