<p>The flexible packing for the withdrawal of liquid has an insertion section for the fitting of an extraction device (2) such as a drinking straw and is formed by an opening constructed in the sleeve of the flexible packing and closed off by a film in the initial state. The film is constructed in such a way that it lies sealed on the fitted extraction device to form a tent top shape. For a taut covering of the opening in the initial state, overlying strips of the film in the region of the folds are interconnected and/or the film is detachably connected to the sleeve.</p> |
