Description

  The present invention relates to a flexible container used for waste accumulation at a construction site or the like.

Heretofore, it has been mainstream to use large containers for the accumulation of waste at construction sites and the like. However, in recent years, a flexible container about 1 m ³ in size is often used because waste is separated into many items, and waste is separated and stored, and it is a method of carrying it out to a treatment facility or plant as needed. Is becoming mainstream.

  The flexible container used in this manner is formed of a resin sheet or a cloth material into a bag having a shape close to a rectangular parallelepiped. Storage of waste etc. utilizes the opening provided in the upper part of the bag body, and the edge part of the opening is equipped with the hanging belt fixed to reverse U-shape. Moreover, the lower part of a bag body is equipped with the inversion belt, By discharging this with a crane etc., the stored waste etc. can be discharged.

  In the flexible container having such a configuration, it takes time and effort to discharge stored items including work such as transfer to a reversing belt from a hanging belt used at the time of conveyance, and the stored items There is a problem such as being caught inside and hard to be discharged. Furthermore, when taking out the storage thing stuck inside by giving a vibration to a bag body etc., the problem in terms of safety, such as a heavy thing may fall at once, is pointed out.

  Under such a background, there has been proposed a flexible container having an opening / closing portion for discharging on the lower surface of the bag as disclosed in Patent Document 1 and Patent Document 2. Moreover, the flexible container which connected the side material which can expand | deploy all is disclosed by patent document 3 to the four sides of the bottom formed in rectangular shape. In addition, in the flexible container currently disclosed by patent document 3, using a string and a surface fastener for fastening of side material is shown.

JP-A-8-268492 JP, 2014-108830, A Japanese Patent Laid-Open No. 2002-326663

  According to the flexible container as disclosed in Patent Documents 1 and 2 in which the opening / closing portion is provided on the lower surface of the bag body, it is necessary to invert the flexible container when discharging the stored items. There is no For this reason, it is considered that the discharge operation of stored items can be performed simply and quickly. However, in the flexible container having such a configuration, if the stored item is heavy, the load may concentrate on the opening and closing part, and there is a risk of falling. Further, in the case where the stored material is a loose material having a relatively small slice, there is a possibility that the stored material may leak from the gap between the opening and closing part.

  Although the flexible container of a structure which is disclosed by patent document 3 comes to be able to discharge stored goods, without reversing a bag body by partially opening a side surface raw material, any stored goods will be When the load is concentrated to the side of the side, the side may be broken.

  Therefore, it is an object of the present invention to provide a flexible container capable of securing the safety at the time of discharge and ensuring the load resistance at the time of lifting while making the dischargeability of stored items favorable.

  A flexible container according to the present invention for achieving the above object is a flexible container provided with a hanging means on a bag body for storing stored items, comprising a freely openable / closable connection portion on one side surface of the bag body The suspending means includes a first belt provided on an open side having the connection portion and a second belt provided on a non-open side opposite to the open side. The connection portion is released when the belt is lifted.

  In the flexible container having the above-mentioned features, the first belt is configured to be shorter than the second belt. By having such a feature, when the flexible container is lifted via the two belts, the flexible container is inclined to the non-open side. As a result, even when the stored item is a heavy item, the heavy item is biased to the open side, and the open side is not unexpectedly opened.

  In the flexible container having the above-mentioned features, the second belt is fixed to the bottom of the bag and not fixed to at least the upper half of the non-open side. By having such a feature, the second suspension belt can be separated when lifting the flexible container with one belt, and can not be lifted when lifting the flexible container with two belts. It will be in contact with the open side. For this reason, when discharging stored goods, it becomes possible to incline and reverse the bag body of a flexible container, without carrying out the replacement of a suspension belt.

  Further, in the flexible container having the above-mentioned features, a hook-and-loop fastener is provided at the connection portion. By having such a feature, it is possible to open and close the open side easily and quickly.

  According to the flexible container which has the above characteristics, the discharge property of stored goods can be made favorable. In addition, it is possible to secure and improve the safety when discharging stored goods. Furthermore, the load resistance at the time of lifting can be maintained well.

It can be regarded as part of the present invention as long as the effects of the invention can be achieved.

[Constitution]
As shown in FIGS. 1, 2 and 4, the flexible container 10 according to the present embodiment comprises a bottom surface 12, side surfaces (open side surfaces 14a, non-open side surfaces 14b-14d), and lids 16b and 16d. On the basis of the bag 18, hanging means (first belt 20 and second belt 22) for hanging the bag 18 are attached. The bottom surface 12, the side surfaces (open side surfaces 14a, non-open side surfaces 14b-14d), and the lids 16b and 16d are all made of a resin sheet or a cloth material, and joining of necessary places is performed by sewing, welding, or other joining means. It is made. In the drawings, the expressions about the bending and the flexibility of the material are simplified.

[Non-open side]
In the case of the flexible container 10 according to the present embodiment, the bottom surface 12 is formed in a substantially rectangular shape as shown in the developed view of FIG. The material which comprises the non-open side 14b-14d) is joined. On the side, one open side 14a and three non-open sides 14b-14d are defined. The non-opened side surfaces 14b-14d are disposed at opposite positions of the open side surface 14a and the pair of non-opened side surfaces 14b and 14d which are oppositely disposed when the bag 18 is configured. 14c, and the abutting sides are joined to each other. In FIG. 4, hatched portions by oblique lines are the contact sides to be joined.

  In the present embodiment, the material constituting the lids 16b and 16d is joined to the upper end of each of the non-opened side surfaces 14b and 14d disposed opposite to each other. The material constituting the lids 16b and 16d may be configured to have a length equal to or greater than half of the width of the non-open side 14c. When the storage container 30 is placed in the flexible container 10 and the upper part thereof is closed by the lids 16b and 16d, parts of the two lids 16b and 16d overlap.

[Open side]
The open side 14 a is provided with a connection. The connection portion can be configured by, for example, a surface fastener 24. By using the surface fastener 24 as the connection portion, the connection portion can be opened and closed (contact and separation) quickly and easily. When the surface fastener 24 is adopted, the hook surface 24a and the loop surface 24b may be disposed on the open side surface 14a and the non-open side surfaces 14b and 14d adjacent to the open side surface 14a, respectively. Specifically, when the hook surface 24a is disposed on the open side surface 14a, a portion that is to be opposed to the loop surface 24b is disposed to protrude to the outer periphery of the side of the open side surface 14a. On the other hand, the loop surface 24b disposed on the non-open side surfaces 14b and 14d is disposed toward the inner surface with the outer periphery that comes in contact with the side of the open side surface 14a as a base point.

  With the surface fastener 24 in such an arrangement form, when the open side surface 14a is closed, the loop fastener surface 24 is a loop surface in a state where the hook surface 24a is bent from the open side surface 14a to the non-open side surfaces 14b and 14d. Connected to 24b. With such a connection form, the force (force in the opening direction) applied to the open side surface 14 a acts in the direction orthogonal to the connection surface of the surface fastener 24. Therefore, high resistance can be provided. On the other hand, when the surface fastener 24 is to be separated, it is sufficient to pull the hook surface 24a in a direction (surface direction) to be separated from the loop surface 24b, so that separation (opening) can be performed with a small force. . Such surface fasteners 24 may be provided at a plurality of locations (three locations in the example shown in FIGS. 1, 2 and 4) between the open side 14a and the non-open sides 14b and 14d. Even when the arrangement of the hook surface 24 a and the loop surface 24 b constituting the surface fastener 24 is reversed, there is no difference in the function as the surface fastener 24.

  Moreover, in the flexible container 10 which concerns on this embodiment, the junction part with non-open side 14b, 14d is provided in the lower end part of the open side 14a. By providing the joint portion in the lower part where the load is concentrated, it is possible to enhance the resistance when carrying the heavy load. Further, by providing the joint portion at the lower end portion of the open side surface 14a, the lower shape can be stabilized when the bag 18 is formed. Thereby, when the flexible container 10 is installed on a mesh pallet or the like (not shown), the lower part of the bag body 18 can be lifted from the bottom of the mesh pallet or the like, and the installation state can be prevented from becoming unstable.

  The suspending means comprises a first belt 20 provided on the open side 14a and a second belt 22 provided on the non-open side 14c. In the case of this embodiment, the first belt 20 and the second belt 22 are each fixed (joined) to the bottom surface 12. And the 1st belt 20 makes the suspending part 20a project on the upper end side of the open side 14a via the open side 14a. In addition, the second belt 22 causes the suspending portion 22a to protrude to the upper end side of the non-opened side surface 14c via the non-opened side surface 14c. The first belt 20 and the second belt 22 are positioned with respect to the open side surface 14a and the non-open side surface 14c via the temporary fixing portion 26, respectively, so that each side surface (open side surface 14a, non-open side surface 14c) and stable when lifting the flexible container 10.

  The temporary fixing portion 26 may be, for example, a surface fastener or the like. In addition, in the case where the temporary fixing portion 26 is a surface fastener, a hook surface or a loop surface which can be attached to and separated from each belt (the first belt 20 and the second belt 22) is provided on each side surface. good. As shown in FIG. 3, the belts may be sandwiched between surface fasteners in which a hook surface and a loop surface form a pair. By providing the temporary fixing portion 26 having such a configuration on the upper end side of each side surface, it is possible to balance when the flexible container 10 is lifted.

[Hanging part]
The hanging portions 20a and 22a are configured to protrude in an inverted U-shape from the respective upper ends of the open side 12a and the non-open side 14c. With such a configuration, the flexible container 10 can be lifted by hooking the hook 40 (see FIGS. 6 to 9) to the U-shaped portion. In the flexible container 10 of the present embodiment, the length L1 of the suspending portion 20a of the first belt 20 is configured to be shorter than the length L2 of the suspending portion 22a of the second belt 22.

  By setting the length L1 of the suspending portion 20a to be shorter than the length L2 of the suspending portion 22a, when the flexible container 10 is lifted, the flexible container 10 is inclined toward the non-open side 14c. The open side 14a closed by the connecting portion of the surface fastener 24 or the like has lower load resistance than the non-open side 14b-14d joined by sewing, welding or the like. Therefore, by tilting the flexible container 10 toward the non-open side 14c, it is possible to prevent the storage item 30 from being biased toward the open side 14a. Thus, even when the storage item 30 is heavy, it is possible to prevent the open side surface 14a from being opened unintentionally.

[Use form]
Next, storage, conveyance, and discharge of materials by the flexible container 10 having the above-described configuration will be described with reference to FIGS. 5 to 9. First, as shown in FIG. 5, the storage items 30 such as materials and waste are put in the bag-shaped flexible container 10. Here, the shape of the flexible container 10 may be maintained by setting it on a mesh pallet (not shown) or the like.

  Next, as shown in FIG. 6, the lids 16b and 16d of the flexible container 10 are closed, and the hanging portion 20a of the first belt 20 and the hanging portion 22a of the second belt 22 are respectively cranes as lifting means Hook on hook 40 Then, the flexible container 10 is lifted. At this time, the lifting posture of the flexible container 10 is inclined toward the non-open side 14c due to the difference between the length L1 of the hanging portion 20a and the length L2 of the hanging portion 22a.

  After transferring the flexible container 10 to the transport position, as shown in FIG. 7, the flexible container 10 is grounded, and the suspending portion 20 a of the first belt 20 is removed from the hook 40. And the surface fastener 24 which is the connection part which has closed the open side 14a is separated, and the open side 14a is open | released.

  After the open side 14a is opened, the hooks 40 pull up the hanging portion 22a of the second belt 22 as shown in FIG. Here, even if the temporary fixing portion 26 (for example, a surface fastener: see FIG. 4) for temporarily fixing the second belt 22 is released manually by hand, the weight of the flexible container 10 and the pulling up by the hook 40 The reaction of force may be used. Since the second belt 22 separated from the non-open side 14c is fixed to the bottom surface 12, the bag 18 constituting the flexible container 10 is connected to the open side 14a as the second belt 22 is pulled up. You will be inclined to When the bag body 18 whose open side surface 14a is in the open state is inclined, the material or the like which is the storage item 30 is discharged from the open portion of the bag body 18 to the outside.

  By further lifting the hook 40 and lifting the second belt 22 from the state shown in FIG. 8, the bag 18 of the flexible container 10 is inclined in a range exceeding 90 degrees as shown in FIG. 9. . As a result, all stored items 30 such as materials stored inside are discharged, and the discharging process is completed.

[effect]
According to the flexible container 10 configured as described above, by providing the opening portion on one side surface of the bag body 18, the discharge property of the stored item 30 can be made favorable. Also, when the flexible container 10 is lifted by making the hanging portion 20a of the first belt 20 provided on the open side 14a shorter than the hanging portion 22a of the second belt 22 provided on the non-open side 14c. The storage item 30 is not biased toward the open side 14a. As a result, it is possible to secure load resistance at the time of lifting.

  Moreover, since the storage item 30 is discharged from the opening part provided on the side surface of the bag 18, safety at the time of discharge can also be enhanced. Furthermore, since the second belt 22 provided on the non-open side 14c is fixed to the bottom surface 12 and can be separated from the non-open side 14c, the bag 18 is inclined only by lifting the second belt 22. , Can be reversed. As a result, there is no need to replace the belt or lift the flexible container 10 to a high position, and it is possible to avoid the danger of the storage item 30 falling from a high place.

[Modification]
In the above-described embodiment, as an example of the connection portion and the temporary fixing portion 26, it is described that a surface fastener is adopted. However, instead of the surface fastener, a string may be adopted for the connection portion or the temporary fixing portion 26. It is because there is no difference in the function in the point of performing opening and closing simply.

  In the description of the above-described embodiment, in FIG. 8 for explaining the process of discharging the storage item 30, the first belt 20 is shown to be an underlay of the storage item 30 in a state of hanging on the ground. However, when it is not preferable that the first belt 20 underlays the storage item 30, the first belt 20 removed from the hook 40 may be stored in the open side surface 14a. In this case, for example, as shown in FIG. 10, a storage portion such as a pocket 28 may be provided on the open side 14a.

 Further, as shown in FIG. 11, the storage side 30 is discharged by winding the open side 14a itself in a roll and fixing it to the joint with the non-open sides 14b and 14d provided on the bottom surface 12 side. When doing, you can avoid getting under it. The open side surface 14a wound in a roll may be fixed by providing a surface fastener 24 or the like at the corresponding portion of the non-open side surfaces 14b and 14d.

  Further, in the above embodiment, when the storage item 30 is discharged, the second belt 22 is lifted after the open side surface 14 a is opened in advance. However, by lifting only the second belt 22 after removing the hanging portion 20a of the first belt 20 from the hook 40, the weight of the stored item 30 acts on the open side surface 14a to promote opening. It is good.
