Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a container bag suitable for storing and transporting powder and granular materials.

Conventional technology Conventionally, this type of container bag has a configuration in which the contents are discharged by opening the discharge port on the lower side while the hanging hand is suspended from a crane hook. .

Conventionally, as a carrying device, a rectangular hole is punched in the center of a base fabric, a lid is sewn to the back side of the base fabric so that the hole can be opened and closed along one side of the base fabric, and a lid is sewn to the back side of the base fabric so that the hole can be opened and closed. One end of each string is connected to the sewing side edge of the lid on the back side, and the other end of each string is connected to a single conductor, and the free end side of the lid is connected to the sewing side edge of the lid on the back side. A guide ring is attached to the edge of the guide ring and the outer edge of the guide ring, and a guide rope is guided to these guide rings, and this guide rope is connected to the guide ring,
Alternatively, a configuration is known in which it is connected to a base fabric or a hanging rope connected to the base fabric. To use this carrier, support the lid with strings and leads;
With the holes in the base fabric closed with the lid, powder or the like is placed on the base fabric and the lid. Then, the suspension rope is suspended from a crane hook, and the powder is transported so as to be wrapped in the base fabric and the lid. After transportation, by untying the guide rope while it is still suspended as described above, the weight of the granular material causes the guide rope to separate from the guide ring, and the lid is pushed downward, allowing the granular material to fall through the hole. .

Problems to be Solved by the Invention However, in the conventional container bag, in order to open the discharge port, the string that closes the outlet must be operated from the center of the bottom side of the container bag. Therefore, it is troublesome to operate the string, and especially when the weight of the contents is large, the contents are discharged from the discharge port all at once, resulting in problems such as dangerous operation.

On the other hand, in the conventional carrier, one end of each string is connected to the edge of the back side of the base fabric on the sewing side of the lid, and the other end of each string is connected to one guide rope. Because this lead rope is connected to a hanging rope, etc. via a lead ring attached to the base fabric, the entire lid cannot be supported evenly, and the lid comes off from the lead rope, causing powder, etc. to fall. There is a risk of In addition, the string that supports the lid is attached to the sewn edge of the lid, independent of the hanging rope, so when the hanging rope is hung with a crane hook, the base fabric and lid are pulled upward by the hanging rope. On the other hand, since the lid is pushed downward by particles, etc., the load concentrates on the connecting parts between the strings, conductors, etc. that support the lid and the base fabric, and these connecting parts are damaged. It is possible and dangerous. In addition, if the lead rope is connected to the suspension rope, when the base fabric is made larger and a large amount of powder or granules is to be transported, the connection position will be higher when the suspension rope is suspended, making it difficult to untie the lead rope. . Furthermore, when the guiding rope is connected to the base fabric or the guiding ring, a load of powder or the like is applied to the connected portion, so that the task of untying the guiding rope is not only difficult but also dangerous.

The purpose of this invention is to simplify the operation of opening the discharge port.
The object of the present invention is to provide a container bag that can be used safely and has improved durability.

Means for Solving the Problems In order to achieve the above object, the present invention includes a discharge port that can be opened depending on the weight of the contents, covers the discharge port, and protrudes by opening according to the weight of the contents. A bag main body equipped with a lid that can be opened and closed, an even number of hanging belts fixed at approximately equal intervals along the axial direction on the outer surface of the body of the bag main body, and a plurality of adjacent sets of hanging belts, The opening/closing lid support member made of a string or belt is connected between the lower ends of the other sets of suspension belts except for one set, and the opening/closing lid support member is connected to the lower end of one of the suspension belts of the set of suspension belts and separated. A connecting/disengaging opening/closing lid support member made of a string or a belt, which is provided with a connecting portion at an end, and which engages with or separates from the opening/closing lid supporting member at an outer central portion of the opening/closing lid, and the opening/closing lid supporting member. A connecting part is attached to the intermediate part of the other hanging belt that is paired with the hanging belt that is connected to the support member, and is connected to the connecting part of the separation end, and the connecting part of the opening/closing lid support member for engaging and disengaging. By releasing the opening/closing lid supporting member from the connecting portion on the hanging belt side, the respective opening/closing lid supporting members and the opening/closing lid supporting member are disengaged due to the weight of the contents.

Effects The present invention has the following effects due to the above-described configuration.

Powder, granules, etc. are stored inside the bag body and transported by being suspended from a crane hook using a hanging belt. At this point, the outside of the opening/closing lid is supported radially by the opening/closing lid supporting member for engaging/disengaging and the opening/closing lid supporting member, and the opening/closing lid supporting member for engaging/disengaging and the opening/closing lid supporting member are provided with hangings arranged at approximately equal intervals. Since it is connected to the belt, it can support the load by distributing it almost evenly. After transportation, the connecting part is released, but at this time, it is easy to do so because the load is distributed and supported almost evenly as described above, and the connecting part is located on the side of the middle part of the trunk. can be solved. When the connecting portion is released in this way, the weight of the powder, etc. causes the detachable opening/closing lid support member to separate from the other opening/closing lid supporting members, and the opening/closing lid and the discharge port are opened due to the weight of the powder, etc. , powder, etc. can be discharged.

are inserted into the connecting portion 24 and tied, and the connecting portions 26, 24
Connect removably. Therefore, the opening/closing lid support members 22, 22, 23 are radial and can evenly support the entire opening/closing lid 11. Then the second
As shown in the figure, contents such as powder and granules are input and stored through the open input port 9. After storing, as shown in FIG. 2, the input slot 9 is tied with a string 10 and stored inside the body 2, and the opening/closing lid 5 is closed by moving the binding tube 8. This allows it to be used for transportation. After transportation, to discharge the contents, a hook 29 of a crane or the like is hung on the hanger 21 to suspend the container bag, as shown in FIG. After that, when the string 28 is untied, the fasteners 27a and 27b are detached due to the weight of the contents as shown in FIG. Along with this, the fasteners 14a and 14b are detached due to the weight of the contents, and the inner cover 12 and outer cover 13 of the opening/closing cover 11 are opened.
At the same time, the binding band 17 of the outlet 16 comes off due to the weight of the contents, opening the outlet 16 and allowing the contents to be provided.

In the embodiment described above, the opening/closing lid 11 is composed of an inner lid 12 and an outer lid 13, but the inner lid 12 may be omitted, or the inlet 9 and the opening/closing lid 5 may be eliminated, and the hanging handle 21 may be replaced. Also install it on the side to connect the outlet 16 to the input port 9.
It can also be used for both. Further, the opening/closing lid supporting members 22 and 23 may be formed into a belt shape. The present invention can be modified in various other ways without departing from its basic technical idea.

Effects of the Invention As is clear from the above explanation, according to the present invention, the bag body is provided with a discharge port, and an opening/closing lid is provided that covers this discharge port and causes the discharge port to protrude depending on the weight of the contents. An even number of hanging belts are fixed to the outer surface of the trunk at approximately equal intervals along the axial direction, and between the lower ends of each set of hanging belts except for one set among the plurality of adjacent sets of hanging belts. An opening/closing lid supporting member is provided in series, and an opening/closing lid supporting member for engaging/disengaging is provided in succession at the lower end of one of the hanging belts of the set of suspension belts, and connected to a separated end of the opening/closing lid supporting member for engaging/disengaging. Since the opening/closing lid supporting member for engaging/disengaging is engaged with another opening/closing lid supporting member at the outer central part of the opening/closing lid, the opening/closing lid supporting member for engaging/disengaging is provided with a connecting portion on the other hanging belt. By connecting the connecting portion to the connecting portion on the hanging belt side, the opening/closing lid support member and the engaging/disengaging opening/closing lid supporting member can be stretched radially to support the entire opening/closing lid almost equally. Moreover, as mentioned above, since the opening/closing lid support member and the opening/closing lid support member for engaging and disengaging are connected to the hanging belt, when the opening/closing lid supporting member and the opening/closing lid for engaging and disengaging are suspended using the hanging belt, The support member can support the load by distributing it almost evenly. Therefore, it can be supported reliably, and damage to each opening/closing lid support member etc. can be prevented and durability can be improved. In addition, by separating the connection part of the opening/closing lid support member from the connection part on the suspension belt side in the hanging state as described above,
Due to the weight of the contents, the opening/closing lid supporting member is detached from the opening/closing lid supporting member, and this separation allows the opening/closing lid and the discharge port to be opened due to the weight of the contents, thereby allowing the contents to be discharged. At this time, since the load is almost evenly distributed between the locking/disengaging opening/closing lid support member and the opening/closing lid supporting member as described above, it is possible to easily perform the work of releasing the connecting portion. Since it is located on the side of the body, this release operation can be carried out without the risk of the contents falling, and therefore the operation of discharging the contents can be carried out easily and safely. . In addition, since the connection part of the opening/closing lid support member for engaging and disengaging is connected to the connection part on the suspension belt side at the middle part of the body, the height of the body can be increased to transport a large amount of powder, etc. Even if the height is high, the connecting part can be located at a height that can be easily reached when hanging, and therefore, the work of releasing the connecting part can be easily performed.
