Disclosed is a container (1) is provided with a removable lid (2). At the top of the side wall of the container there is provided an outwardly projecting bead or bead portions (5, 5′, 5″) abutted by the lid (2) the lid having a skirt (2a) with downwardly and/or inwardly facing cams (10, 11, 12, 15, 16, 17). The lid (2) is relatively stiff, and the inside of the skirt (2a) has a concave abutment surface (2a′) near its lower edge portion, the abutment surface being of a substantially spherical, conical or superelliptical curvature and abutting the bead or bead portions (5, 5′, 5″). The side wall of the container is provided with a support shoulder (7) beneath the bead or bead portions (5, 5′, 5″). The cams are partially snap cams (10, 11, 12) mounted beneath the abutment surface (2a′) and adapted to catch the abutment surface (2a′) of the skirt when it abuts the bead or bead portions (5), and partially one or more small fulcrum cams (16, 17) projecting inwardly or downwardly seen from the lower edge portion of the skirt (2a) and optionally extending along a considerable angle. The fulcrum cams (16, 17) are of such a height (h) and are arranged with respect to the snap cams (10, 11, 12) in such a way that they allow at least one of the snap cams to be released from the snapped engagement with the bead or the bead portions (5, 5′, 5″) when the lid (2) is tilted around two of the fulcrum cams, while they are made to abut the support shoulder (7).
