The invention relates to caps for sealing beverages in PET bottles for the food industry. The cap for sealing beverages in PET bottles, which has an elongated upper chamber on the roof thereof, said chamber having a top surface and a side wall abutted by vertical stiffening ribs, the bottom edges of which rest on the roof of the cap, wherein the roof of the cap rests on a lower side wall having a thread on the inside thereof and fine ribbing on the outside to facilitate unscrewing, is characterized in that a rubber coating is applied to the vertical stiffening ribs that rest on the roof of the cap and abut the side wall of the elongated upper chamber. The technical result is a reduction in slippage on the surface of the upper part of an elongated cap comprising an elongated upper chamber (1) that is reinforced around the outside by vertical stiffening ribs (2), and the possibility of unscrewing the cap during use in any weather conditions, while fulfilling present-day requirements with respect to ease of opening and also making it possible to retain standard capping equipment at bottling plants. |
