Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to an inner bag used for container transportation.

[0002]

[Prior art]

 When transporting luggage using container containers, generally, an inner bag that has a bag-shaped body that has a substantially hexahedral structure during expansion is used. To store and transport your luggage. By using the inner bag, for example, it is possible to protect the luggage from dew condensation, prevent the luggage from polluting the container container, or prevent foreign matter from entering the luggage.

Conventionally, various types of inner bags have been proposed, and one of them has a structure in which a load such as a powder or granular material is unloaded by dumping up. In the inner bag of this structure, an extension portion extending in the outflow direction of the luggage is provided on the front surface of the bag-shaped body, and a flow path for the luggage is formed in this extension portion. At the time of unloading, the bag-shaped body is inclined by dumping so that the front side is lower than the rear side, and the baggage is poured from the extension part into the unloading container used for storage or small-quantity transportation. .

[0004]

[Problems to be solved by the device]

 In a conventional inner bag that is unloaded by dumping up, generally, the opening width at the starting end position of the extension channel is made smaller than the distance between the left and right side surfaces of the bag-shaped body. For this reason, when the bag-shaped body is tilted and unloaded, the baggage that slips on the bottom surface of the bag-shaped body and reaches the boundary between the bottom surface and the front surface of the bag-shaped body does not flow out to the extension channel. Remains at the boundary of this.

Therefore, the applicant of the present invention thought that the following items (1) and (2) should be used in order to reduce the load remaining inside the inner bag. (1) The opening at the starting end of the flow path of the extending portion is provided almost entirely between the left side surface portion and the right side surface portion of the inner bag. (2) At the beginning portion of the flow path of the extension part, the extension part and the bottom part of the bottom part of the extension part are arranged so that the position of the inner surface of the bottom part of the bag part is substantially the same. Join the bottom part.

[0006] On the other hand, in order to prevent foreign matter from entering the luggage during unloading or to prevent dust generated from the luggage from spreading at the unloading place at the time of unloading, a string is usually used for the extension portion. The flow path of the extension part can be closed by opening and closing. Then, the end opening (loading port) of the extension channel is connected to the load inlet of the unloading container, and then the extension channel is opened for unloading. At this time, if the portion near the end of the extension channel is closed and the extension channel is closed, the cargo will flow into the extension channel up to the narrowed portion. It is difficult to connect the end opening of the to the load inlet of the unloading container. Therefore, in order to improve workability, it is better to narrow the portion as close as possible to the starting end of the extension passage.

However, in the case where the extension passage is formed as described in (1) and (2) above, if the portion near the start end of the extension passage is squeezed, the extension portion extends in the squeezed state. When the length is short and the squeezing is released, the extension length of the extension portion becomes long and the difference between these lengths becomes large. Therefore, after connecting the container and the container for unloading and then releasing the squeeze, move the container and / or the container for unloading to increase the separation distance between these containers, which causes the baggage to stagnate in the extension passage. This work is troublesome because it is necessary to eliminate the slack in the extension channel to the extent that it does not exist.

Further, although the extension channel is not so large as in the case where the extension channel is formed as described in (1) and (2) above, such a slack in the extension channel is the starting end of the extension channel. It also occurs when the opening width in a portion is made smaller than the distance between the left and right side surfaces of the bag-shaped body.

The present invention has been made in view of the above-mentioned points, and therefore, an object of the present invention is that even if the extension passage is opened in a state in which it is connected to an unloading container, the slack in the extension is almost eliminated. Not to provide an inner bag.

[0010]

[Means for Solving the Problems]

 In order to achieve this purpose, the inner bag of the present invention has a bag-shaped body having a substantially hexahedral structure having a front surface portion, a rear surface portion, left and right side surfaces, a top surface portion and a bottom surface portion, and the bag-shaped body inside a container container. A lid member for connecting to a wall surface, a front surface portion having an extending portion extending in the outflow direction of the luggage and forming a passage for the luggage, and a lid member for opening and closing the extending portion passage in an openable and closable manner. And an operating portion for opening the lid member from the outside of the bag-shaped body.

[0011]

[Action]

 As described above, according to the present invention, the lid member that opens and closes the extension passage is provided, and the operation portion that opens the lid member from the outside of the bag-shaped body is provided. Therefore, the lid member can be opened from the outside of the bag-like body through the operating portion while the extension passage is still connected to the unloading container. Further, since the extension channel is opened and closed by opening and closing the lid member, the length of extension of the extension from the front surface portion hardly changes when the extension channel is opened and when the extension channel is closed.
