Abstract: A cardboard container for drinks and a process therefore, the container having a perimetral wall (2) and a bottom wall and being characterised in that it comprises means (4) for the supporting thereof when it is stackedly arranged in a respective container (1).

Abstract: A cup-shaped receptacle has an outer bead in its opening area for clipping on a plastic lid. The lid 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, the U-web of which is situated below the height position of the constriction and the inner leg wall of which forms a part of a dome wall of a dome which extends upwardly beyond the height position of the constriction. The lid recess extends downwards beyond the height position of the constriction 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.

Abstract: The invention is directed to a pile-up lid each having an upper wall (1) and an element (2) arranged around the perimeter of said upper wall (1) and which forms a lip (3) protruding above said upper wall (1), and skirt (4) extending below said upper wall. The lid is made by a process of bringing together in a synchronous manner external sector elements (9) and internal sector element (10) in radially opposite directions so that, owing to the forced approach of the contact surfaces of the external and internal sector elements (9, 10) with said upper lip (3) of said lid interposed between them, a reeding pressure-moulding is obtained on both the inner and the outer surfaces of said upper lip (3), giving said lip (3) an outline apt to allow piling up on other similar lids.
