<p>Most of the problems with containers, especially those containing a liquid, are experienced when tilting on a filling opening, particularly when the container is completely filled. For such containers (1), a cap (2) is proposed, which comprises a bottom, a hollow cylindrical body and an external flange (4). The face of the flange orientated towards the cap bottom is fixed to bellows (5) linked to the container (1) or being part of the latter. One or several emptying openings (7) are arranged in the portion of the hollow body which is surrounded by the bellows (5). By means of such arrangement, the content of the container can flow out only when a downward pressure is exerted on the cap (2).</p> |
