ABSTRACT:
A cup-shaped receptacle has an outer bead in its opening area for clipping on a plastic lid, which has a circumferentially continuous clamping groove for receiving the bead. The clamping groove is continued outwards by an elastically deformable constriction, and inwards by an outer wall of a circumferentially continuous, U-shaped lid recess, whose U-web of is situated below the height position of the constriction and whose inner leg wall forms a part of a dome wall of a dome which extends upwardly beyond the height position. The lid recess extends downwards beyond the height position and has an outer diameter at its outer surface which is adapted to the inner diameter of the receptacle wall such that the lid recess functions at least as a centring and guide projection for the lid-clip-on action, which projection slidingly co-operates with the receptacle wall already at least while the bead passes the constriction.
