The Vinolok is a special closure made of glass which is popular thanks to its pleasant weight and aesthetic shape. A synthetic sealing ring (high top) creates a good seal. This closure is not only popular for products like oil, but also for spirits (up to 80% vol.). If this cork is used for commercial applications, it must be made tamper-proof in accordance with FPVO, e.g. though the application of a shrink foil (open at the top). This grip cork is not suitable for horizontal storage.
