Abstract
The invention is directed to a push-pull closure for a drink container including a mouthpiece holder. The container includes a pin, which projects into the through-opening of the mouthpiece holder; several bars, parallel to the pin and arranged around the pin, which are connected to the mouthpiece holder and to the pin; a mouthpiece that is axially displaceable and sealing with respect to the mouthpiece on the outer circumference and accommodating the pin in the further through-opening; at least one circumferential seal element, which blocks and unblocks the passage of liquid through the further through-opening in an closing/opening position of the mouthpiece in the mouthpiece holder; and several ribs of a soft elastic material, axially extending on the circumference of the mouthpiece at the bottom, wherein the mouthpiece may be inserted into the mouthpiece holder, and the bars can engage free spaces and the ribs engage recesses between the bars.
