End wall closure for bulk material transport bag |
摘要 |
A flat reusable fill/discharge closure for the end wall (bottom or top) of a cloth bag for transporting bulk materials comprises a flexible tube folded back into itself to form a long inner fill/discharge tube and a short outer closure tube having a length less than the radius of an opening in the bag end wall; the tube fold is sewn into the periphery of the end wall opening of the bag with the closure and fill/discharge tubes projecting outwardly. A flat closure is effected by tying the fill/discharge tube closed, stuffing it into the bag interior, and then closing the closure tube by a drawstring mounted in its outer end.
