Mechanism for opening and reclosing the outflow opening for emptying a container

A mechanism for opening and reclosing an outflow opening in a lid of a container for emptying the container comprising

• a latch comprising a protrusion to initiate movement of the latch, located on a top surface of the latch, wherein the latch is connected rotationally to the lid;
• at least one arched guide (4) formed on a bottom surface (1b) of the lid (1), with an arched guiding surface (4a) going down rotationally with respect to the bottom surface (1b) of the lid (1);
• at least one arched hatch (5) with an arched surface (5a) shaped on a bottom surface (2b) of the latch (2), wherein said arched surface (5a) goes down rotationally with respect to the top surface (2a) of the latch (2), wherein the hatch (5) is fitted slidingly on said arched guide (4), so that the arched surface (5a) of the latch (2) contacts the arched guiding surface (4a) of the arched guide (4), wherein the lid (1) and the latch (2) are configured such that in a closed position the top surface (2a) of the latch (2) contacts the bottom surface (1b) of the lid (1) at least around the outflow opening (3) for emptying the container, whereas in an open position the top surface (2a) of the latch (2) is distant from the bottom surface (1b) of the lid (1);
• and wherein the open and closed positions are based on the rotation of the latch (2) by application of force on the protrusion to rotate the latch (2) along the arched guide (4).
