Retaining ring

Cork stopper retention system for sparkling wines

The proposed solution solves a well-known safety issue related to the risk that when a sparkling wine is uncorked, the cork, expelled from a bottle with an overpressure of 6 bar, can reach high speeds and may strike the operator or bystanders, causing severe physical damage, such as the loss of or injury to an eye.  With the proposed system, the cork is retained by a polymer strap connected, with two rings of the same material, on one side to the cork, on the other to the neck of the bottle, thereby ensuring its retention, without detracting from the traditional ritual associated with uncorking sparkling wine. The retention system is produced with a biodegradable polymer that means it can be disposed of together with the cork stopper.
