Zork

Australia developed alternative closure for bottles, first introduced in 2004 to the public. It consists of the three parts cap, foil and piston. From polyethylene manufactured cap encloses the bottleneck. The foil made of aluminum (like a screw cap ) is welded inside the cap and prevents oxygenation. The also made of polyethylene piston is mounted inside the bottle and extends like a plug into the neck of the bottle. Only this with the film welded piston has contact with the wine. The piston material was from the AWRI (Australian Wine Research Institute) tested and shows no negative effects on the wine. All materials have been approved by the US Food and Drug Administration (FDA) and the EU. Polyethylene is one of the purest types of polymers and has been used in the food and beverage packaging industry for many years. The lower part of the cap consists of a spiral around the neck looped tear-off, with which the lock is released and with a "pop" is removed. A 12-month test series revealed that the degradation of sulfur dioxide slower than with plastic corks, but faster than with screw caps or natural corks. See also below closures,
