A snap-action non-separable connection between a lid and a container, comprising snap-action profiles formed in a top part of the container around an opening for filling the container, and the snap-action profiles formed in the lid, where said profiles interlock, characterised in that the snap-action profiles in the top part (8) of the container (6) are formed on a front surface (8a) of the top part (8) into segments (9) which do not contact one another, where formed on a side surface of each segment is at least one snap protrusion (10), and where in the top part (1a) of the lid (1) are slots (2), on the side surface of which formed is at least one snap ledge (4), and where a number of the slots (2) in the lid (1) is equal to the number of said segments (9) formed around an opening (7) of the container (6), where said segments (9) fit into said slots (2) in the lid (1) so that resting on said snap ledges (4) in the slots (2) in the lid are said snap protrusions (10) of the segments (9), and the top parts of the segments above the snap protrusion (10) contact tightly the slots (2) in the lid (1), and a bottom surface (1c) of the lid (1) contacts the front surface (8a) of the top part (8) of the container (6), and wherein, formed in the lid the snap ledge (4) around its bottom edge is a socket (5) to accommodate a flange (11) of the container (6).
