US 2011/0011868 A1 · Reclosable Container End

Abstract

A resealable container and/or resealable container end for foods such as beverages. The end includes an opening and a pull-tab closure which includes a plug for sealing the opening. The closure may be fabricated from a thermoplastic coated foil. A portion of the foil is formed as a cup located within the opening to include a lip to engage the edge of the opening or a grove which is engaged by the edge. A resilient material such a cured plastisol fills the cup and cooperates with the cup to form a plug. The thermoplastic hermetically seals the closure over the opening and a tab on the closure permits the user to remove the closure and plug from the opening. The plug can be reinserted into the opening after removal to reseal the opening with a generally fluid-tight seal.
