  • Patent number: 6467625
    Abstract: A bulk bag comprising a flexible body having a bottom and sidewalls and at least one pair of tubular fork tine receiving members including a rigidifying insert and a flexible sleeve depending from the bottom of the body for removably inserting the rigidifying insert therein. Further, the receiving members are arranged in substantially parallel spaced relation across the bottom of the body such that fork tines from a forklift are insertable into the receiving members to lift the body. In one aspect, the rigidifying insert has a mating component which clamps around the sleeve and onto the rigidifying insert in order to preclude the rigidifying insert from being withdrawn from the sleeve. In another aspect, the sleeve is made from a material with sufficient elasticity to stretch to receive the rigidifying insert and then contract to inhibit the rigidifying insert from being withdrawn from the sleeve.
