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. |

1. A push-pull closure for a drink container, comprising:
a mouthpiece holder (2), which has a through-opening (7) and means for holding (5), by way of which the mouthpiece holder is sealingly and detachably fastenable on the edge of an opening of the drink container; a pin (12), which projects into the through-opening (7) of the mouthpiece holder (2), wherein a circumferential gap exists between the pin (12) and the through-opening (7) of the mouthpiece holder; several bars (9), parallel to the pin (12) and arranged around the pin (12), which are connected to the mouthpiece holder (2) at the top and to the pin (12) at the bottom; a mouthpiece (3) with a further through-opening (16) for a beverage, which can be inserted into the circumferential gap so as to be axially displaceable and sealing with respect to the mouthpiece (7) on the outer circumference and accommodating the pin (12) in the further through-opening (17), at least one circumferential seal element (22, 23) between the pin (12) and the further through-opening (17), which blocks the passage of liquid through the further through-opening (17) in a closing position of the mouthpiece (3) in the mouthpiece holder (2), and unblocks the passage of liquid through the further through-opening (17) in an opening position of the mouthpiece (3) in the mouthpiece holder (2), and several ribs (24) of a soft elastic material, axially extending on the circumference of the mouthpiece (3) at the bottom, between the several ribs are axially extending free spaces (25), wherein the mouthpiece (3) is insertable into the mouthpiece holder (2), so that the bars (9) engage into the free spaces (25) and the ribs (24) engage into recesses (10) between the bars (9), stopping surfaces (26) present at the top edge of the ribs (23) bear against the bottom side of the mouthpiece (3) in an upper position of the mouthpiece (3), and the bars (9) bend over neighboring ribs (24) into the free spaces (25) when the mouthpiece (3) is rotated with respect to the mouthpiece holder (2), and the mouthpiece (3) is displaceable from the through-opening (7) under reduced extraction force. |
