ABSTRACT:
A pack for flowable material, includes a tube (1) having at least one longitudinal seam, with a base and a lid (2) mounted at its ends. The lid (2) is made of thermoplastics material without any base material, is welded to the tube (1) and has a pouring device (8). The tube (1) is made of base material such as cardboard, coated with thermoplastics material on at least one side. The lid (2) is a separate, prefabricated part fitted by means of a flange (5) engaging round the top edge (6) of the tube (1) and welded to the edge (6). This lid (2) has a part (21) of its surface at a lower level than its outer surface, with part of the lower level surface (21) extending near to the edge (6) of the tube, in such a way that the lid (2) engages round the edge (6) of the tube substantially in a U shape in the region of said part (21 ) of the lower level surface.
