Snap lugs on the second part engage bead segments on the firt part to hold the second part in closed position. The diameter of the skirt of the first part includes a radial flange that extends circumferentially about most of the periphery of the skirt. The flange is connected integrally to an outer radially deflectable wall panel. The skirt of the second part is smaller than the diameter of the flange so that the flange projects radially beyond the lid skirt and the lid skirt cannot be raised readily. A shoulder projects axially from the flange to center the lid and support the skirt against radial deflection. By pr…
