<p>The container is formed from a hollow vessel, with its opening, once the container is filled, surmounted by a push-on lid. The lid has the shape of an inverted dish. The lower edges (4) of the vertical walls of the lid comprise indentations. Its inner face, as well as that of the bottom of the container, has rough surfaces, generally in the form of grooves. The horizontal wall of the lid is pierced with small holes along a line parallel to its periphery. Its vertical walls are pierced with small holes (12) along a line parallel to its periphery. In an alterntive form, the horizontal wall of the lid comprises a central hole, slots which are situated on lines connecting the centre of the lid to the centres of the sides, and slots which are situated on lines connecting the centres of two adjacent sides of the lid. Other alternative forms are envisaged. <IMAGE></p> |
