<p>A method of making an improved seal between a drinking container (1), or part of a drinking container (14), and a drinking straw (20). This is achieved by providing the drinking container (1) or an associated part (14) with a permanent bulge (2a, 2b) that forms a double seal (6, 19) against the drinking straw (2) after insertion. The same device also provides increased resistance against the drinking straw (20) unintentionally slipping out.</p> |
