One way closing system uses plastic closing device used to seal bottle contents according to thermal contraction principles and able to be opened using fingers through its perforation

摘要

Plastic closing device is employed, which according to thermal contraction principles is used to seal the contents of a bottle and can be opened by the fingers without appliance by its perforation. Through a wider perforation, it can prevent harmful over-pressurization of the bottle. Inside the top of the closing device, control over the pressure and/or quality of the contents is given through its integrated material properties. The surface of the closing device can be used to display advertising. The tip of the closing device can be provided with functional or decorative imitations of other closing systems in form of crown seals.
