Description

[Detailed description of the invention] This invention relates to an improvement of a transport bag suitably used for transporting powder, granules, pieces, etc.

Conventionally, a relatively long bag body is formed using a flexible sheet member such as synthetic rubber or tarpaulin as a means of transporting powder or granular materials, and powder is attached to the top and bottom of the bag body, respectively. BACKGROUND ART Various bags have been proposed and widely used, each of which has an input path and a discharge path for granules and the like, and which are configured to be openable and closable.

By the way, in this type of transportation bag, a hanging device is provided at a predetermined position on the bag body to facilitate loading and unloading operations using a forklift, etc., but this hanging device is not attached to the bag body. It consists of hanging rings placed at the top of each outside and hanging strings that connect these hanging rings to each other, so when inserting the hanging strings into the forks of a forklift during loading or unloading work, It is necessary for the worker to hold the suspension string and insert it into the fork each time, which has the disadvantage that the work becomes troublesome.

From this point of view, a self-supporting suspension strap has been proposed in which a rigid yet flexible suspension strap is attached to the top of a transport bag in an inverted U-shape. However, although these conventional slings are convenient for use with forklifts, when stacking multiple transport bags during loading etc., the flexibility of the slings is used to forcibly bend them. Therefore, when stacking transport bags are held from the side, the bottom part gets caught on the free-standing suspension strap, making it difficult to work, and when used frequently, the free-standing function is impaired. There are other difficulties.

Therefore, the inventor made repeated improvements and prototypes to create a transport bag that would allow for smooth and easy loading and unloading operations. It is configured in a substantially portal shape and the pair is arranged so as to intersect at the top of the transporter,
On the other hand, a plurality of pockets are provided at predetermined locations on the outer surface of the bag body, a flexible portion is provided at the end of the sling, the flexible portion is attached to the inside of the pocket, and a shape-retaining portion of the sling is provided. It has been found that by configuring the bag to be able to be taken in and out of the pocket together with the flexible part, the transport bags can be stacked without applying stress to the shape-retaining part of the sling, and the above problem can be solved.

Therefore, an object of the present invention is to provide a transportation bag with a self-supporting suspension strap on the top, by providing a pocket portion on the side of the transportation bag and configuring the end of the suspension strap to be freely put in and taken out. To provide a transport bag that allows loading and unloading work to be performed smoothly and easily without applying unnecessary stress to the shape-retaining portion of the sling, and that can maintain the self-sustaining function of the sling well for a long period of time. There is something to do.

In order to achieve the above object, the transportation bag according to the present invention uses a flexible sheet member to form a bag body, and a material input path and a material discharge path extend from the top and bottom of the bag body, respectively. In the transportation bag, the suspension straps are configured to be openable and closable, and a suspension strap with a shape-retaining member inserted is attached to the outer surface of the bag main body, and the suspension strap is configured in a substantially gate shape, and a pair of the suspension straps are configured to cross each other. A flexible portion is extended for a predetermined length at the end of these suspension bands, and the tip of the flexible portion is attached to the inside of a pocket provided on the outer surface of the bag main body to suspend the bag. The present invention is characterized in that the shape-retaining part of the band can be freely put in and taken out of the pocket together with the flexible part.

Next, preferred embodiments of the transportation bag according to the present invention will be described in detail with reference to the accompanying drawings.

In FIG. 1, reference numeral 10 indicates a transport bag main body in which powder or granules are filled and transported, and this main body 10
is made of waterproof and tough flexible sheet material such as synthetic rubber, vinyl chloride tarpaulin, polypropylene cloth, or waterproof canvas, and is formed into a cylindrical shape, preferably a rectangular cylindrical shape. It is. In this case, since the flexible sheet member constituting the bag body 10 is in direct contact with the filling material, it has oil resistance, chemical resistance, or food hygiene properties depending on the filling material accommodated in the bag body. It is necessary to ensure compliance with the standards.

A filling port 12 and a discharge port 14 for powder and granular material are provided at the top and bottom of the main body 10, respectively, and a cylindrical input channel formed of the same sheet material as the bag main body 10 is provided in the filling port 12 and the discharge port 14, respectively. 16 and the discharge path 18 are attached by appropriate means such as welding or sewing, and the input path 16 and the discharge path 1 are attached by appropriate means such as welding or sewing.
A tightening device 20 made of a tightening cord or the like is attached to a part of the opening 8 so that the input port 12 and the discharge port 14 can be opened and closed as appropriate.

Further, each outer surface of the bag body 10 has the body 10
Pockets 22 formed of a sheet member similar to the above are provided, and inside these pockets 22, suspension bands 24,
Both ends of the suspension strap 24 are fixed to each other, and the suspension strap 2
4 and 24, a gate-shaped shape-retaining piece 26 made of, for example, a thin steel plate is inserted and arranged. In this case,
Each end of the suspension straps 24, 24 is attached to the bottom (see FIG. 2) or the inner upper part (see FIG. 3) of each pocket 22, and the shape-retaining piece 26 is attached to the suspension strap 24,
Rather than inserting and arranging the entire length of the sling 24, a flexible portion 28 of a predetermined size is provided at both ends of the sling 24, and when the suspension straps 24, 24 are not used, a part of the shape retaining piece 26 is inserted along with the flexible portion 28. It is constructed so that it can be stored in and out of each pocket 22 at will.

Note that it is preferable that a reinforcing band 30 for reinforcing the pocket 22 is provided continuously. Also,
In the embodiment shown in FIG.
Although the suspension bands 24, 24 are shown in the case where they are arranged in a crosswise manner, the suspension bands 24, 24 can also be arranged in parallel, as shown in FIG.

Next, the functions and effects of the transport bag according to the present invention constructed as described above will be explained.

When using, first tighten the discharge passage 18 with the tightening tool 2.
