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 shown in FIG. 2, for example, as shown in FIG. 2, a relatively long case body 10 is formed of a flexible sheet material such as synthetic rubber or tarpaulin as a bag for transporting powder or granular materials. Transport bags are widely used in which a filling port 16 and a discharge port 18 for materials such as powder or granules are provided in a surface 12 and a bottom surface 14, respectively, so as to be openable and closable.

However, when a transport bag made of such a flexible sheet member is filled with material, the lower side of the main body bulges outward, making it difficult to maintain its regular shape, which reduces loading efficiency during transport. 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 these problems, for example, a constriction part is provided on the side of the packaging body to improve shaping properties, and the flexible sheet members that make up the packaging body are formed in double layers. Various improvements have been made, such as reinforcing the mesh by inserting a net in between, but in these cases, there are disadvantages in that not only the manufacturing cost increases, but also the folding when not in use is troublesome, making it inconvenient to handle.

[Purpose of the invention]

An object of the present invention is to provide a transportation bag having the simplest structure, which is attached to surround the outer surface of a cube-shaped transportation bag, and has reinforcing plates integrally provided on at least two opposing sides to prevent deformation. An object of the present invention is to provide a shape-retaining support band for a transport bag, which can improve shape-retaining properties and strength during filling with materials, and is convenient for handling during transport.

[Key points of the invention]

In order to achieve the above-mentioned object, the shape-retaining support band for a transport bag according to the present invention is a support band that includes a side surface that surrounds the outer surface of a transport bag that is configured in a cubic shape by a flexible sheet member. The supporting band is characterized in that a reinforcing plate is housed in at least one set 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 configuration in which the support band is composed of three continuous side parts, and reinforcing plates are respectively accommodated in the side parts at both ends of the support band.

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, the embodiment shown in FIG. 1 consists of a support band having side parts 20, 22, and 24 surrounding three sides of a transport bag (see FIG. 2) having a cubic configuration. It is constructed from a flexible sheet material similar to a transportation bag. However, reinforcing plates 26 made of plywood or the like having a thickness that does not easily bend and deform are housed inside the side surfaces 20 and 24 at opposite ends of the support band.

Incidentally, fasteners 28 and 29 are provided at both ends of the side surfaces 20 and 24 to securely hold them together.

The support belt thus constructed is placed around three sides of a transport bag filled with about 173 to 1/2 of the material, and fasteners 28 and 29 are fastened to each other on the other side. By tightening, the side surfaces 20.24 with opposing reinforcing plates 26 press against the sides of the transport bag, and the other side parts 22 reinforce the sides of the transport bag, so that it retains its shape when filling is completed. It is possible to improve the properties and strength (see Figure 3). In addition, if this supporting band is held on the side of the transport bag before filling 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, the side parts 30, 32, 34.3 completely surround the four sides of the transport bag.
This is a support band having 6 parts. In this case, the reinforcing plates 26, 26 are housed inside a pair of opposing side surfaces 30, 34, and the side surfaces 30, 34 at both ends are
．． Fasteners 28 and 29 are provided at the ends of 34, respectively.

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, 44, 46, 48 that surround and hold each side of the bag are extended, and reinforcing plates 26, 26 are housed in at least one set of opposing side parts. In this case, fasteners 28 and 29 are appropriately provided at the upper end of each of the side parts 42, 44, 46, 48, respectively, for tightly holding the opposing side parts together on the top surface of the transport bag.

With ε configured in this way, it is possible to strengthen the shape retention and improve the strength of the transport bag, as in the above embodiment.

〔Effect of the invention〕

As is clear from the various embodiments described above, the shape-retaining support band for a transportation bag according to the present invention is manufactured separately from the cube-shaped transportation bag, and when the transportation bag is used, By enclosing and fixing on the outer surface, it is possible to easily and inexpensively enhance the shape retention and strength of the transport bag. In particular, by providing reinforcing plates on at least one pair of opposing side surfaces of the support belt, not only the shape retention of the transport bag is sufficiently stabilized, but also plywood of a predetermined thickness can 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-mentioned 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.
