1. A mechanism for opening and reclosing the outflow opening for emptying a container, especially a beverage container, comprising a latch to open and reclose the said outflow opening in a container lid, wherein the latch is fitted with hatching elements connected slidingly to the container lid, and wherein the lid features an actuating element for initiating movement of the latch form on the top surface of the latch, characterised in that it contains at least one pair of sliding surfaces (3, 103), each of them incorporating at least one section in the shape of a convex arch going down with a respect to a top surface of the lid (1, 101), where moving on said pair of sliding surfaces (3, 103) when shifting the latch (6, 106) is at least one pair of hatching elements (7, 107) formed on the top surface of the latch (6, 106), and where ends (3a, 3b, 103a, 103b) of the sliding surfaces (3, 103) are positioned at different heights with respect to the bottom surface of the lid (1, 101) around the outflow opening (2, 102), so that the end (3a, 103a) of each sliding surface (3, 103) from which the movement of the latch (6, 106) starts towards the opening of the outflow opening (2, 102) is positioned higher relative to the bottom surface of the lid (1, 101) around the outflow opening (2) than its other end (3b, 103b), and where the latch (6, 106) in the closed position contacts the bottom surface of the lid (1, 101) around the outflow opening (2, 102), and wherein the latch (6, 106) is moved downwards relative to the bottom surface of the lid (1, 101) around the outflow opening (2) to the open position so that in the open position the latch (6, 106) is distant from the bottom surface of the lid (1, 101) around the outflow opening (2).
