ABSTRACT:
A molded tethered safety closure device for use on bottles containing pressurized liquids such as champagne or sparkling wines comprising a cork or closure element and a retainer collar joined by an intercoupling section. The intercoupling section is comprised of a tabbed tear strip and a tether strip that are integrally formed in a helical configuration extending in a plurality of turns from the cork to the collar. The tether strip and the tear strip are interconnected by a pair of grooved frangible webs that can be torn by pulling on the tear strip. This allows the tear strip to be manually removed from the intercoupling section. Following removal of the tear strip, the helical tether strip interconnects the cork and the retainer collar, thus enabling the cork to be released from the bottle without flying free.
