Description

[Detailed description of the invention] [Technical field to which the invention pertains] The present invention relates to a shape-retaining support band for a transport bag that is suitably used for transporting powder or granular materials formed into a cubic shape by a flexible sheet member. Regarding.

[Prior art and its problems]

Conventionally, as a bag for transporting powder or granular materials, a relatively long bag body 10 is formed of a flexible sheet member such as synthetic rubber or tarpaulin, as shown in FIG. A filling port 16 and a discharge port 1 for materials such as powder or granules are provided on the surface 12 and the bottom surface 14, respectively.
Transport bags equipped with 8 can be opened and closed are widely used.

However, when a transportation bag made of such a flexible sheet member is filled with materials, the lower side of the bag body bulges outward, making it difficult to maintain its regular shape, which reduces loading efficiency during transportation. However, there are drawbacks such as a decrease in the amount of water and an increase in transportation costs, and the fact that it is easily torn by sharp objects such as nails or knives, resulting in the contents leaking out. Therefore, as a means to overcome such problems, for example, a constriction part is provided on the side of the bag body to improve shaping properties, and the flexible sheet member that makes up the bag body is formed in double layers. Various improvements have been made, such as inserting a net or inserting a net for reinforcement, but in these cases, not only do manufacturing costs increase, but folding when not in use is troublesome, making handling inconvenient.

[Purpose of the invention]

It is an object of the present invention to attach to the outer surface of a cube-shaped transportation bag so as to surround it, and to attach at least two opposing
A reinforcing plate is integrally provided on the side to prevent deformation, which improves the shape retention and strength of the transport bag when it is filled with materials, making it convenient for handling during transport. To provide a support band for bag shape retention.

[Key points of the invention]

In order to achieve the above-mentioned object, the shape-retaining support band for a transportation bag according to the present invention includes a support band that includes a side surface that surrounds the outer surface of a transportation bag configured in a cubic shape using a flexible sheet member. The supporting band is characterized in that a reinforcing plate is housed in at least one pair of opposing side surfaces of the supporting band, and a tightening fastener is provided at each opposing end of the supporting band.

In this case, manufacturing costs can be reduced by using plywood of a predetermined thickness as the reinforcing plate.

In the above-mentioned shape-retaining support band, it is possible to suitably adopt a structure in which the support band is composed of three continuous side parts, and reinforcing plates are housed in each of the side parts at both ends.

The supporting band can also be constructed of four continuous side parts.

Furthermore, as an alternative, the support band may have a side surface that abuts the bottom surface of the transport bag, and a side wall extending from each side edge of the side surface that surrounds the outer surface of the transport bag.

[Embodiments of the invention]

Next, embodiments of the shape-retaining support band for a transport bag according to the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a perspective view showing an embodiment of a shape-retaining support belt according to the present invention. That is, in the embodiment shown in FIG. 1, a side surface portion 20 surrounding three sides of a cube-shaped transportation bag (see FIG. 2);
22 and 24, and the support band is constructed of a flexible sheet member similar to a transport bag.
However, the side surfaces 2 at opposite ends of this support band
0 and 24, there is a reinforcing plate 26 made of plywood or the like having a thickness that does not easily bend or deform.
Place them in their respective storage locations. Incidentally, fasteners 28 and 29 are provided at both ends of both side surfaces 20 and 24, respectively, for mutually tightening and holding.

The supporting band constructed in this manner is placed around three sides of a transport bag filled with about 1/3 to 1/2 of the material, and fasteners 2 are placed on the other side.
By mutually concluding and tightening 8 and 29,
Side parts 20 and 24 with opposing reinforcing plates 26 press the sides of the transport bag, and the other side part 22 reinforces the sides of the transport bag, improving its shape retention and strength when filling with material is completed. (See Figure 3). Note that if this support band is held around the side of the transport bag before being filled with material, the transport bag can be erected and the material filling operation can be facilitated. Furthermore, even if the shape-retaining support band of this embodiment is arranged with the side surface portion 22 in contact with the bottom surface of the transportation bag, the side surface of the transportation bag can be reinforced in the same manner as described above.

FIG. 4 shows another embodiment of the shape-retaining support band according to the present invention. That is, in this embodiment, a support band is constructed that has side parts 30, 32, 34, and 36 that completely surround the four sides of the transport bag. In this case, a reinforcing plate 2 is installed inside a pair of opposing side surfaces 30 and 34 as in the above embodiment.
6, 26 are housed and arranged, and side parts 30, 34 at both ends are arranged.
Fasteners 28 and 29 are provided at the ends of each.

With this configuration, all sides of the transport bag are surrounded and held by the support band, and as a result, the shape retention and strength of the transport bag are further strengthened.

In the embodiment shown in FIG. 4, the reinforcing plate 16 may be arranged to be accommodated on all three or four side surfaces of the support band.

FIG. 5 shows still another embodiment of the shape-retaining support band according to the present invention, which has a side surface portion 40 that comes into contact with the bottom surface of the transport bag, and has side edges 40 attached to each side edge of the transport bag. Side parts 42, 4 surrounding and holding each side of the bag
4, 46, 48, and at least the opposing 1
The structure is such that reinforcing plates 26, 26 are housed on the side surfaces of the set. In this case, each side part 4
Fasteners 28 and 29 are appropriately provided at the upper ends of the bags 2, 44, 46, and 48, respectively, for tightly holding the opposing side portions together on the top surface of the transport bag.

With this configuration as well, it is possible to strengthen the shape retention and improve the strength of the transport bag, as in the embodiments described above.

[Effects of the Invention] As is clear from the various embodiments described above, according to the shape-retaining support band for a transportation bag according to the present invention, it is manufactured separately from the cube-shaped transportation bag, and By encircling and fixing it to the outer surface of the transport bag during use, it is possible to easily and inexpensively strengthen the shape retention and improve the strength of the transport bag. especially,
By providing reinforcing plates on at least one set of opposing side surfaces of the support belt, the shape retention of the transport bag is not only sufficiently stabilized, but also plywood of a specified thickness should be used as the reinforcing plates. Therefore, the support band can be manufactured at extremely low cost.

In addition, since this support band is manufactured separately from the transport bag, the transport bag can have the simplest structure with no internal or external reinforcement, and it is also easier to fold the transport bag after use. Moreover, the supporting band can be easily folded, and it is possible to rationalize the transportation work of powder and granular materials and to significantly reduce the transportation cost.

Furthermore, in the above-described embodiment, the most typical fastener was shown as a means for tightly holding the shape-retaining support band to the transport bag, but various bands and strings may be used for this type of fastener. Not only can it be obtained, but its mounting position, length, direction, etc. can be arbitrarily modified.

Although the preferred embodiments of the present invention have been described above, it goes without saying that various design changes can be made without departing from the spirit of the present invention.
