Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a transport bag used for transporting powder, granules, pieces, etc.

Conventionally, as a means of transporting powder and granular materials, a relatively long bag is formed using a flexible sheet material such as synthetic rubber or turbolin, and the top and bottom of this bag body are filled with powder. BACKGROUND ART Various bags have been proposed and widely used, each having an input path and a discharge path for granules, etc., which can be opened and closed.

By the way, in this type of transport bag, a metal fitting, a string member, or a tensioning device combining these is used as a means to close the input path and the discharge path, but these tightening devices not only increase manufacturing cost but also have trouble opening and closing. Operation is complicated;
In addition, when the knot is closed with a small material, rainwater and the like are absorbed, causing the knot to come undone and become even more troublesome.

In order to overcome these shortcomings, the inventor conducted extensive research and prototype production, and as a result, the inventor provided a closing plate around the opening of the input channel and/or the discharge channel, thereby turning a part of the closing part inward and symmetrically. By configuring the occluding plate to be closed, a covering means is provided on one side green portion of the occluding plate in the folded state, and the covering means is configured to be fixed on the other side green portion of the occluding plate, It has been found that opening and closing operations of the input channel and/or the discharge channel can be easily performed. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a transport bag which has a simple structure and allows easy opening and closing operations of an input passage and/or an output passage.

In order to achieve the above object, in the present invention, a flexible sheet member is used to form a bag body, and a material input path and a material discharge path are extended from the top and bottom of the bag body, respectively. In a transportation bag configured to be openable and closable and provided with a closing member at the entrance of the material input path and/or the discharge path, a closing plate configured to regularly fold inward at the entrance is provided around the transportation bag. It is characterized in that a pair of opposing outer surfaces of the closing plate in the folded state are provided with coupling means for keeping the entrance portions hermetically sealed from each other.

In the above transport bag, the coupling means may include, for example, a cover piece extending from one side of the closure plate, and a hook-and-loop fastener that connects the inner side of the cover piece and the side surface of the closure plate to each other. Alternatively, a locking band may be provided on one side of the closing plate, and a buckle member coupled to the locking band may be provided on the other side of the closing plate.

Further, by providing a cover on the top of the bag body to cover the material input path, it is possible to prevent rainwater or the like from entering the inside of the bag body.

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

In FIG. 1, reference numeral 10 indicates the main body of a transportation bag filled with powder or granules, etc., for transportation. It is constructed into a cylindrical shape, preferably a rectangular cylindrical shape, using a movable sheet member such as polypropylene cloth or waterproof canvas.

In this case, since the movable sheet member constituting the bag body 10 is in direct contact with the filling, it has oil resistance, chemical resistance, or food sanitation properties depending on the filling contained in the bag body. It is necessary to have compliance with standards, etc.A filling row 2 and a discharge port 14 for powder and granular material are provided at the top and bottom of the main body 10, respectively, and the bag body is inserted into the filling port 12 and the discharge port 14. A cylindrical input passage 16 and a cylindrical discharge passage 18 formed of sheet members similar to those of 10 are attached by means such as welding or sewing, and a tightening device 20 made of a tightening cord or the like is attached to a part of the discharge passage 18. The configuration is such that the discharge row 4 can be opened and closed as appropriate.Hangers 22 are appropriately disposed on each outer surface of the bag body so that the forklift,
It is preferable to use it for convenience when loading and unloading using a crane or the like. Although the input passage 16 may be configured as a cylinder, it is preferably configured as a rectangular cylinder with a substantially square cross section. Obstruction plate 26 made of comb and sexual parts
is attached, and the opposite sides of the entrance part 24 are folded inwardly and symmetrically at the middle part, so that the entrance part 24 is substantially closed.

In this case, the closing plate 26 is formed wide so that the closing portion 24
It is preferable to configure the input passage 16 so that it can stand on its own when opened. A cover piece 28 is attached to one side twill portion of the closing plate 26 in the folded state, and a hook and loop fastener 30 is provided inside the free end of this cover piece 28, and a hook and loop fastener 30 is provided on the outer surface of the other side twill portion of the closing plate 26. A surface fastener 32 is provided, the flap piece 28 is bent, and the surface fastener 30 and surface fastener 32 are engaged to maintain the closed state of the entrance portion 24.

In addition, by fixing a tightening belt 34 to one side of the closing plate 26 and disposing a buckle member 36 on the other side, and locking the belt 34 with the buckle member 36, the entrance portion 24 can be closed. It is configured to hold the bag body I.
A covering body 38 consisting of a movable sheet section similar to that of the main body is provided around the top of the U, and the folded input channel 16 is covered by this covering body 38 and fixed with a stopper (not shown). It is preferable to configure the main body so that the main body is covered with rainwater, etc., because it can prevent rainwater from entering the main body during transportation or bond trading (see Fig. 3).

Furthermore, it is preferable to form the input passage 16 into a cylindrical shape and to integrally provide the closing plate 26 at the entrance 24 of the cylindrical input passage 16, since this greatly simplifies the manufacture of the transport bag. (See Figure 4).

Next, the mode of use of the transport bag according to the present invention constructed as described above will be explained. In use, first, the discharge passage 18 is tightened with the tensioner 20 to close the discharge row 4, and the discharge port 18 is appropriately folded, and then wrapped with the cover piece 40.
Furthermore, the bag body 10 is closed by locking the cover piece 40 with a locking tool 42.

Next, the bag main body 10 is held suspended by means such as a belt via the hanger 22, and the closing plate 26 of the input path 16 is pushed out to open the closing part 24, and the bag body 10 is filled with powder or the like. After filling the inside of the main body with powder and granules in this way, the closing plate 26 is folded inward and the hook-and-loop fastener 30 of the night cover piece 28 is engaged with the hook-and-loop fastener 32, thereby completely blocking the input passage 16. is achieved (see Figure 2). In addition, when opening the input passage 16, it is sufficient to release the engagement of the hook-and-loop fasteners 30 and 32 and then push out the closing plate 26. As mentioned earlier,
According to the transport bag according to the present invention, the structure is simple and easy to manufacture, the opening/closing operation of the powder input channel is easy, and it is possible to reliably prevent rainwater etc. from entering the inside of the transport bag. It has various advantages such as:

Although preferred embodiments of the transportation bag according to the present invention have been described above, the present invention is not limited to these embodiments.
For example, the closing structure of the discharge passage may be constructed in the same manner as the closing structure of the input passage in order to reduce manufacturing costs, or a hook-and-loop fastener may be provided on the inner surface of the closing plate to more reliably maintain the closing state of the entrance. Of course, various design changes can be made without departing from the spirit of the invention, such as configuring it as follows.
