ABSTRACT:
A container for liquids in the form of a foldable box with an internal flexible bag for containing the liquid. The box is formed in a manner which enables it to be expanded from a folded flat configuration to a three dimensional configuration. Two opposed sides of the box and the box end panels feature centrally positioned fold or crease lines. As the box is expanded from its folded flat to its three-dimensional configuration, open slots are formed at the ends which enable the bag to be inserted into the box. The bag is thereafter filled and the open slots at the box ends are sealed using tape or another fastening system. Following use, the box can be readily reused by cutting the fastening tape, refolding it flat and later refilled it with another bag.
