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 9-sided 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 with the advent of strong bag-making materials, it has become possible to manufacture large-capacity transport bags, but in this case, the bottom opening of one bag is closed with a bag tightening cord, etc. In transport bags, the operation to open the contents outlet is performed directly below the bottom of the bag, making the operation complicated and dangerous.

In addition, in a type of transport bag in which the filling discharge passage member extending from the bottom opening of the bag body is appropriately gathered and closed, and this discharge passage member is laterally covered, the bottom part of the bag body bulges out, making it difficult to shape the bag. There were drawbacks such as a decrease in loading efficiency.

Therefore, the inventor conducted intensive research to create a transportation bag that allows the bottom discharge port to be opened and closed easily and safely and has good loading efficiency. An inner cover piece and an outer cover piece are disposed on the inner cover piece, a band is extended from the tip of the inner cover piece, the end of which is fixed to the outer peripheral side of the main body, and the inner cover is extended from the approximate center of the band. A string member is provided that extends to the tip of the lid piece and is free at its end, and a plurality of fastening strings are attached to the end of the band that is fixed to the outer peripheral surface of the main body. At the same time, attach a locking loop to the inner end of the outer cover piece and provide a hook-and-loop fastener retainer #+ on the bottom of the case body, and after holding the inner basket piece with the hook-and-loop fastener retainer piece, remove it by folding or other means. When the discharge passage member with the outlet closed is held, and then the inner cover piece is covered with the outer cover piece, the string material extending from the approximate center of the band is inserted through the loose locking of the co-pressure outer cover piece. Afterwards, by configuring this string material to be tightened and held with a fastening string, the desired purpose was achieved and the dancing was stopped.

Accordingly, a general object of the present invention is to provide a transport bag which allows the bottom discharge port to be opened and closed easily and safely, and which has good loading efficiency.

A main object of the present invention is to form a long packaging body using a recursive sheet member, provide a filling inlet and a discharge port at the top and bottom of the packaging body, respectively, and discharge the filling from the discharge port. It consists of a transport bag with a passage member extending therein, an inner cover piece and an outer layer piece are arranged around the discharge passage member, a band is extended from the tip of the inner cover piece, and the end is attached to the packaging body. adheres to the outer part of the
A string material extending 4 degrees from the approximate center of the band to the tip of the inner lid piece and free at the inner end of the band is provided, and a fastening string is attached to the end of the band to form a one-sided lid piece. To provide a transport bag characterized in that a locking loop is attached to the tip of the outer cover piece, and a hook-and-loop fastener holding piece is provided at the bottom of the main body at the inner end of the outer cover piece.

In the above-mentioned transport bag, if the inner lid piece and the outer lid piece are provided symmetrically on both sides of the discharge passage member, the structure can be simplified and handling operations can be facilitated. Alternatively, the bottom of the main body can be made stronger by forming it with more pieces and attaching a locking loop to the tip of each piece.

Furthermore, if a guide pocket for the band is provided at the bottom of the main body, the band can be slid and the discharge port can be opened easily.
