Abstract
A liquids package is described which comprises a tube (1) comprising side walls (3-6) connected to one another by a longitudinal sealing seam (2) and consisting of synthetic plastics coated paper. The package is provided with a synthetic plastics top injection moulded onto one end of the tube (1). In order to provide greater dimensional accuracy in the top portion of such a package with favorable properties with regard to sealing-tightness and ease of opening, it is envisaged that the tube (1) be at its top end and on at least two oppositely disposed edges (11, 11') extended by respective wall panels (8, 9, 8', 9') which extend at an angle from the side wall (3, 5), the top being integrally moulded on that edge (10) thereof which is towards the center of the top.
