The inventive task comprises providing a new design for dispensing carbonated, including strong carbonated beverages relating to a “siphon” type and made mainly from polymer materials adapted for using semirigid vessels from polyethyleneterephthalate of the prior art or known structures. A closure is affixed on a neck 1 of a bottle 2 made from polyethyleneterephthalate, the closure comprises a body 3, sealing member 4, pressure part 5 and a feed pipe 6. The body is embodied with recesses 7 and 8 arranged at opposite sides and connected by an orifice 9. The neck is positioned in the recess 7. The body 3 has a spout 11 a cavity of which communicates with the orifice cavity 9 between recesses 7 and 8 of the body 3. The sealing member 4 is disposed inside the recess 7of the body 1 and in the cavity of the neck 2 end portion having a cavity 12, inside which a locking element 13 is arranged and overlapping orifice 9 between body's cavities and connected with the sealing member 4 adapted for displacement and opening the cavity of the orifice 9. The pressure part 5 is fixed oversized along the perimeter in the recess 8 of the body 3 and has an elastic membrane 15 with a stem 16 disposed in the orifice 9 adapted to interact with the locking element 13 for its displacement and opening the cavity of the orifice 9. |
