FIELD: transport, package.
SUBSTANCE: proposed plug two types of cork material mix strongly chemically bonded and produced from two types of granular material with different distribution in sizes at the following percentage: a) from 10 to 90% of cork material mix produced from granules 1 with granule size of 2 to 10 mm; b) from 90 to 10% of cork material mix 2 made from granules 2 with granule sizes of 0.25 to 4 mm. Note here that total surface between two said mixes is irregular because of mutual penetration while mix 2 stays in contact with wine. Invention covers also the method of fabrication of described corks.
EFFECT: cork made up of two parts reliably glued together.
