A snap-action non-separable connection between the lid and container, comprising snap-action profiles formed in the top part of the container around the opening for filling the container, and snap-action profiles formed in the lid, where the said profiles interlock, characterised in that the snap-action profiles in the top part (8) of the container (6) are formed on the front surface (8a) of that part into segments (9) which do not contact one another, where formed on the 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 the number of the slots (2) in the lid (1) is equal to the number of the said segments (9) formed around the opening (7) of the container (6), where the said segments (9) fit into the said slots (2) in the lid (1) so that resting on the said snap ledges (4) in the slots (2) in the lid are the 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 the bottom surface (1c) of the lid (1) contacts the front surface (8a) of the top part (8) of the container (6).
