[0002]

2. Description of the Related Art Conventionally, in order to prevent collapse of loads in a rectangular box, a plurality of stacked loads are loaded along an outer edge between a rectangular box above and below the rectangular box which is in contact with the upper and lower sides of an appropriate height. The load was fixed by gluing tape around the box and connecting the upper and lower rectangular boxes.However, fixing with the tape prevents the box surface from becoming dirty when the tape is removed, or the box surface in the case of a paper box. Peeling off The printed letters and pattern on the box will also come off. In addition, the peeled gum tape cannot be used again, and it becomes waste, which hinders the environment and wastes resources.

Therefore, conventionally, as shown in FIG. 4, a surface fastener 2 and a handle 3 are provided at one end of the belt-shaped body 1, and the surface of the other end of the belt-shaped body 1 which is overlapped with the surface fastener 2 and is detachably attached thereto. There is a fastener having a fastener 2'and a handle 3 ', and a slit 4 provided in the longitudinal direction near one of the ends.

[0004]

In order to stack and transport a plurality of rectangular boxes containing various articles, first, they are stacked and placed on a pallet of a lift and moved to a loading platform such as a truck. The square boxes stacked on top of each other cannot be moved because the load collapses unless some fixing means is applied. In addition, even if the cargo is loaded on the truck bed, the cargo collapses during transportation.

Therefore, there is a conventional tightening tool which is wound around and fixed around the outer edge between the upper rectangular box and the lower rectangular box which are in contact with the upper and lower sides of the appropriate height position. In use, first place the box between two rectangular boxes that vertically contact the ends of the bandage of the tightening tool, sandwich the band and temporarily fix the band, and make a round around the cargo so that the temporary lock does not come off. The end part of is fastened with the hook-and-loop fasteners 2 and 2 ', but at this time, the end part where the slit 4 is provided is overlapped on the upper side,
Hold the handle 3'at the lower end through the slit 4, hold the handle 3'at the upper side with the hand on the opposite side, and firmly tighten and fasten it so that both ends overlap with each other.

However, in this method, since the temporary fixing method simply sandwiches the vicinity of the end of the strip between the upper and lower boxes, it may come off if the strip is pulled around the cargo. It has a defect that it occurs frequently and the band-shaped body is twisted and difficult to wind. Further, even when fastening the vicinity of both ends of the belt-like body with the surface fasteners, it was necessary to hold a handle with each hand and tighten with both hands before that, so a very large force was required.

In view of the above points, the present invention is capable of securely fixing the band-shaped body, which is wrapped around a plurality of stacked rectangular boxes, to prevent the collapse of the load to the rectangular box, and facilitates the tightening. The present invention aims to provide a tightening tool for preventing the collapse of the load of a rectangular box.
