Abstract
Abstract A semi-rigid impervious package for liquid products comprising a container which can be cardboard, having therein an impervious lining made, for example of thermoplastic material. The container is polygonal in cross-section and comprises a number of panels each having a flap at each end. The flaps form a continuous flange at each end of the container to which are fixed a rigid end cap and a base, respectively. One panel has tear-line perforations providing a tab for opening the container. The lining is a tube sealed transversely at each end forming two corners at each end which are folded over the end of the tube in such a way that one corner can be drawn through the opening made in the container when the tab is torn and lifted. The corner can then be cut and used as a pouring spout for dispensing the contents of the lining.
