The insertion part (1) of the drinking straw fits through an opening (6) in the drink-container (9).. The outer piece of straw (2) is outside the container. A middle piece (3) is sealed in the opening and has an elastic, partly conical seal-stopper (4). The front end of the sealing-stopper is next to a cylindrical stopper-piece. The end of the sealing stopper outside the container-opening has a thrust-piece (5) with larger external diameter than the diameter of the container-opening. A link (7,8) is in front of and or behind the sealing-stopper. |
