Bottle stopper means for wine bottles

摘要

A tamper-proof bottle stopper intended to be used for closing wine bottles. The stopper means is of a composite nature and includes a stopper body having an integral upper flange portion which is situated in the closed position above the annular end surface of the neck of a bottle and abuts against the latter when the stopper body proper is pressed into the neck. The upper portion of the stopper body is corrugated or fluted on the radially outer surface thereof. The stopper body defines a cavity open at the upper end and closed at the lower end into which a gas-tight stopper insert is placed. The composite stopper means further includes a fluted cap that engages and coacts with the fluted portion of the stopper body so as to prevent a rotary motion of the cap relative to the stopper body. The cap is provided with a skirt projecting downwardly on the outer surface of the neck of a bottle. The cap, and more particularly its skirt, are of relatively small diameter and of a resilient material adapted to be expanded and mounted on a neck of relatively large diameter of a bottle and then to contract to said relatively small diameter. The cap includes a readily removable annular tearoff strap which, when torn off, severs the cap peripherally, and allows removal of the stopper body and of its insert from the neck of the bottle.
