A container is formed by separating a pushed-in cup in which a lower portion and an upper portion of the side wall are more rigid than a flexible middle portion present in between. The container can be extracted in a simple manner by taking the upper portion of the side wall with one hand and holding a protruding gutter at the bottom with the other hand. Furthermore, the container has a cylinder which is to be pushed downwards between the lower portion and upper portion of the side wall after the cup has been extracted. |
