Wiederverwendbarer Flaschenverschluß

摘要

The bottle closure has a stopper (1) which can be pressed into the neck. The stopper is designed as a truncated cone (5) and is surrounded by a rubber elastic sleeve in the form of an O-ring (2). It ends at the top in a knob (3) and the O-ring (2) is held in a groove (4) let into the stopper underneath the knob. The stopper can extend into a thickened area (6) whose diameter is preferably no larger than the diameter of the truncated cone in the area of the knob. The length of the cone can be a multiple of the diameter of the knob. ADVANTAGE - The reusable stopper ensures a tight reliable seal.
