ABSTRACT:
A bag of tough, flexible material, sealed to be liquid tight except for filling and emptying access ports, is designed for mounting in a standard transportation container. The bag is then filled with a bulk liquid and transported in the container to a desired destination where it is again emptied. To avoid the transportation cost of returning many such bags to the point of origin, while nevertheless not simply discarding them, the present invention provides the third alternative of so constructing each bag that, after use, it can be cut to become suitable for use as a tarpaulin. For this purpose the bag is constructed of a central, generally cylindrical, elongated portion extending at each end into a curved end portion. Tie down devices, i.e. flaps each containing a rigid eye for receiving a tie down rope, are arranged in a pair of circumferential rows extending around the periphery of the central portion near each end portion and in a further pair of adjacent parallel rows extending longitudinally along the central portion between the circumferential rows. By cutting the used bag longitudinally between the latter pair of rows and peripherally outwardly of the circumferential rows, the central portion is transformed into a rectangular sheet with the tie down devices disposed around its periphery.
