sealing facilities. SUBSTANCE: invention relates to devices designed for tight sealing of vessels, particularly, to caps made of elastic material. Proposed cap has cylindrical side wall with inner thread and cap bottom. Sealing projection in place of conjugation of wall bottom engages with end face part of vessel neck. Stopping element made on inner surface of cap bottom engages with side surface of vessel neck. Stopping element is made in form of radial distance ring. Sealing projection has ring flat parallel to inner surface of cap bottom and adjoining cylindrical side wall of cap. It has also ring conical surface mating through larger base with ring flat ands through smaller base, with radii distance ring in place of its contact with cap bottom. Stiffening ribs are made on inner surface of cap bottom inside radial distance ring. EFFECT: simplified design, provision of high degree of vessel sealing. 2 cl, 1 dwg |
