Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a bag that is expanded inside a cargo transportation container and receives powder and granular material therein.

(Prior Art) When granular materials such as grains and chemicals are transported in a general container rather than a special container, they may come into contact with the inner wall of the container and get dirty, which may impair the product value. Therefore, an inner bag is expanded inside the container, and powder and granules are loaded into the inner bag.
This inner bag is usually disposable after one use.

By the way, this type of conventional inner bag is provided with a loading port into which a loading pipe is inserted, and a discharge port to which a discharge pipe is connected, on the door side of the container.

(Problems to be solved by the invention) The conventional inner bag has two openings as described above, which is a cause of high manufacturing costs. Another disadvantage is that it takes time and effort to connect the discharge pipe to the discharge port. Furthermore, because the discharge port cannot be made too large due to its design, there is also the problem that the discharge speed of the powder and granular material is kept low.

Furthermore, since air could only enter and exit through small loading and unloading ports, it was necessary to force air into the bag when it was expanded.

The object of this invention is to obtain an inner bag for a container that can eliminate such drawbacks.

(Means for solving the problem) In order to achieve this purpose, this invention includes a bag body having an opening at one end, and upper and lower parts extending from the ceiling and bottom of the bag body, respectively, and working together to close the opening. To provide an inner bag of a container which has a lid and has rising edges connected to the side surfaces of the bag body on both sides of the lower lid.

(Function) When using, expand the inner bag inside the container, raise and secure the lower lid, and lower the upper lid as well. Next, a loading pipe is inserted into the bag between the lids and the powder is loaded. After loading, the upper and lower lids are joined together to close the opening.

When unloading luggage, open the bottom cover and spread it out horizontally. Then, since the lower lid has edges on both sides that connect to the bag body, the lower lid acts as a shooter. Therefore, if you tilt the container,
The powder in the bag is discharged through the shooter,
For example, falling into the trap of acceptance.

(Example) An inner bag as an example of this invention is shown in FIG. This inner bag is entirely made of sheet material such as plastic, and has a rectangular inner bag body.
has a size that corresponds to the inner diameter of the container used.

An opening 2 is provided at one end of the bag body 1 and on the door side of the container.
An upper lid 3 extending from the ceiling of the bag body 1 and a lower lid 4 extending from the bottom of the bag body are provided above and below the opening.

On both sides of the lower lid 4, edges 4a that are continuous with the side surfaces of the bag body 1 stand up.

When using this inner bag, the strings 5a and 5b attached to the ceiling and lower part of the bag body 1 are tied to fasteners inside the container, and the bag body 1 is expanded inside the container.

Next, as shown in FIG. 2, both edges 4a of the lower lid are folded inward to raise the lower lid 4, and the string 5c at the end of the lower lid 4 is tied to the upper part of the container door. Furthermore, the second
As shown by the chain line in the figure, pull the string 5d attached to the edge 4a of the lower lid upward and tie it to the top of the container door.

In this state, the upper lid 3 is lowered, the loading pipe 6 is inserted into the inner bag from between the upper and lower lids 3 and 4, and the granular material is loaded into the inner bag (Fig. 3). When the stacking is finished, tie the strings 5e and 5f of the upper and lower lids 3 and 4 together (the fourth
), close the container door. before closing the door
If necessary, as shown in FIG. 5, a square timber 8 may be placed at the door of the container 7 to prevent the cargo from leaning against the door 9.

When unloading the cargo, open the door and tighten the strings 5e and 5f.
, open the lower cover 4, and tie the string 5 as shown in Figure 6.
The lower lid 4 is extended approximately horizontally by fixing the lower lid 4 on the ground. When the lower cover is extended like this, the lower cover 4
has a rim 4a that connects to the bag body 1, so
The lower lid 4 becomes a shutter.

Therefore, if the container 7 is tilted, the powder inside will slide down from the opening 2 through the shooter.
It flows into a receiving hopper (not shown).

(Effects) According to this invention, the opening at one end of the bag body is covered by the upper and lower lids, so the loading pipe can be inserted between the lids and the powder and granules can be loaded inside. can be included. Therefore, there is no need for a dedicated loading port, which has been associated with conventional products, and manufacturing costs can be reduced.

There are raised edges on both sides of the lower lid that connect to the sides of the bag body, so when the lower lid is opened, it becomes a shooter, through which the powder and granular material of the cargo is discharged to the outside. Therefore, there is no need for a conventional discharge port for connecting a discharge pipe, and the manufacturing cost can be reduced and the trouble of connection can be saved. In addition, the discharge port of conventional devices limited the discharge speed of powder and granular materials, but since there is no discharge port, the cargo can be unloaded in a short time.

Furthermore, since air can freely flow in and out of the inner bag through the opening, there is no need to forcibly inject air when spreading the powder or granules, as is the case in the past.
