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, for example, a flexible sheet member made of synthetic rubber, turbolin, etc. is used to form a relatively long casing body, and powder is attached to the top and bottom of this casing body, respectively. BACKGROUND OF THE INVENTION A bag body is widely used in which an input path and a discharge path for granules, etc. are attached, and the input path and discharge path are configured to be openable and closable.

By the way, in this type of transportation bag, a metal fitting, a string member, or a tightening device that combines these is used as a means to block the input path, but these tightening devices not only increase the manufacturing cost but also are complicated to open and close. Moreover, when the knot is closed with a string member, it absorbs rainwater and becomes difficult to untie. Therefore, in order to overcome these drawbacks, the inventor conducted extensive research and trial production, and as a result, a holding tube was provided on the outer periphery of the material inputting path to store the inputting path in a folded state, and a holding tube was installed parallel to the opening of this holding tube. By attaching a closing member whose both ends extend slightly outward from the diameter of the opening, and holding this closing member with a holding means provided on the shoulder of the main body, the opening and closing operation of the input channel can be performed. It was discovered that this can be done easily.

SUMMARY OF THE INVENTION Accordingly, a general object of the present invention is to provide a transport bag that is simple in structure and allows for easy opening and closing of material input channels.

The main object of the present invention is to form a transport bag using a flexible sheet, and to have a material input passage and a material discharge passage extending from the top and bottom of the packaging body, respectively, so that these passages can be opened and closed. A holding cylinder is provided on the outer periphery of the material input path to store the material input path in a folded state,
A closing member is attached parallel to the opening of the holding cylinder and both ends thereof extend slightly outward from the diameter of the opening, and means for holding the closing member is further provided on the shoulder of the mounting body. We also provide transportation bags.

In this transport bag, the holding cylinder is a cylindrical or truncated conical cylinder with approximately the same diameter, and the closing member is two opposing flexible plate-like members or rod-like members whose ends are connected and fixed. A member in which the middle portion of the member is curved, or a single plate-like member or a rod-like member is used. The holding means may include a pair of pockets disposed opposite to each other on the shoulders of the main body with the holding cylinder in between, or a midpoint between the pair of pockets and a straight line connecting these pockets, and approximately relative to the straight line. A belt member provided adjacent to a bag portion or a closure member provided in a 90° direction and a buckle member provided on a shoulder portion of the main body are used. Other objects and advantages of the present invention will become more apparent from the following description.

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 this case, since the flexible sheet member constituting the packaging body 10 is in direct contact with the filling material, the flexible sheet member constituting the packaging body 10 has oil resistance, chemical resistance, or food hygiene properties depending on the filling material accommodated in the packaging body. It is necessary to ensure compliance with the standards. Preferably circular powder filling ports 12 and discharge ports 14 are provided at the top and bottom of the main body 10, respectively.
A cylindrical input channel 16 and a cylindrical discharge channel 18 formed of the same sheet material as the main body 10 are attached to the filling port 12 and the discharge port 14 by means such as welding or sewing, and a part of the discharge channel 18 is attached. A tightening tool 20 made of a tightening cord or the like is attached to the outlet 14 so that the discharge port 14 can be opened and closed.

In addition, it is preferable to appropriately arrange hanging tools 22 on each outer surface of the main body 10 to facilitate loading and unloading using a forklift, a crane, or the like. A holding cylinder 24 is provided on the outer periphery of the input path 16 to accommodate the input path 16 in an appropriately folded state.

This holding cylinder 24 is formed into a cylindrical shape with approximately the same diameter using a sheet member similar to that of the main body 10, but preferably has a truncated head with the diameter of the upper opening 26 set to be slightly smaller than that of the base. The opening 26 is closed by attaching a closing member 28 formed into a conical shape and consisting of two opposing flexible plate members or rod members whose both ends are connected and fixed in a flexible manner to the opening 26 of the holding cylinder 24. Configure to retain.
In this case, both ends of the closing member 28 are extended slightly outward from the opening 26, and these extended ends are connected to the locking parts 30, 3.
Configure as 0. On the other hand, at the top of the main body 10, there is a pocket portion 32 at a position opposite to the holding cylinder 24, for example, at a position offset parallel to the diameter line of the holding cylinder 24, preferably on the diameter line of the holding cylinder 24. , 32 are provided, and locking portions 30, 3 of the closing member 28 are provided in the pocket portions 32, 32, respectively.
It is configured to insert and hold 0 respectively.

Next, the mode of use of the transport bag according to the present invention constructed as described above will be explained.

When using the transport bag, first secure the discharge channel 18 with the tightening tool 2.

8 is appropriately folded and then wrapped in a cover piece 34, and this cover piece 34 is further secured with a locking tool 36 to secure the main body 10.
The bottom portion is closed, and then the main body 10 is suspended via the hanging tool 22, and the granular material is filled into the main body 10 through the opening 16a of the input path 16.

In this case, the middle portion of the input channel 16 is held by the closing member 28 of the holding cylinder 24 and is in a closed state, but the weight of the powder and granules to be filled naturally spreads it out, so the powder and granules are There is no risk of hindrance to the filling operation. After filling a predetermined amount of powder into the packaging body 10 in this way,
The input channel 16 is appropriately folded and stored in the holding cylinder 24, and the locking parts 30, 3 attached to the opening 26 of the holding cylinder 24 are
0 into the pockets 32, 32 of the main body 10 and held therein, the input passage 16 is closed (see FIG. 2).
