Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a transport bag suitably used for transporting powder, granules, pieces, etc.

Conventionally, in this type of transportation bag, various improvements have been made to the opening of the bag body in order to facilitate loading and unloading of the contents. In addition, various improvements have been made, such as using a flexible sheet member to make the bag foldable in order to simplify the transportation of the empty bag after the contents have been discharged.

Various such improvements have been made, and the advent of strong bag-making materials has made it possible to manufacture large-capacity transportation bags, but in this case, the bottom opening of the bag body must be closed with a tightening cord, etc. In this type of transport bag, the operation to open the contents discharge port is performed directly below the bottom of the bag, which is complicated and dangerous. A type of transport bag in which the discharge passage member is appropriately gathered and closed, and the discharge passage member is covered with a cover, has the disadvantage that the bottom of the bag bulges, reducing shaping and loading efficiency.

Therefore, the inventor conducted extensive research to create a transport bag that allows the bottom discharge port to be opened and closed easily and safely, and that also has good loading efficiency.
An inner cover piece and an outer cover piece are arranged around the discharge passage member extending from the discharge port, and a band is extended from the tip of the inner cover piece, and the end thereof is attached to the outer peripheral side of the bag body. A string member is fixedly attached to the bag body, extends from the approximate center of the band to the tip of the inner lid piece, and is provided with a free string material at the end thereof, and a plurality of fastening strings are provided at the end of the band member fixed to the outer peripheral surface of the bag body. Attach a locking loop to the tip of the outer cover piece, and provide a hook and loop fastener holding piece to the bottom of the bag body at the inner end of the outer cover piece,
After holding the inner lid piece with the hook-and-loop fastener holding piece, the discharge passage member with the outlet closed is held by means such as folding, and then the inner lid piece is covered with the outer lid piece and the outer lid piece is locked. It has been found that the intended purpose can be achieved by inserting a string material extending from approximately the center of the band through the loop and then tightening and holding the string material with a fastening string.
