Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a flexible container capable of easily transporting and storing raw materials such as powder and granules, and more particularly to a safe flexible container capable of safely opening a discharge port on the bottom surface thereof to discharge a filling material.

[0002]

[Prior Art]

 The flexible container is established in JIS Z1651. Conventionally, in the bottom discharge type flexible container, the flexible container is placed on a dedicated stand to untie the bottom discharge port, or the worker is positioned on the bottom while the flexible container is suspended and the discharge port is Either untie the parts, or remove the bottom cover of the flexible container and hang the flexible container to let the filling material discharge naturally.

[0003]

[Problems to be solved by the device]

 There is no particular problem in terms of safety when using the above-mentioned flexible container on a dedicated stand. However, in the case of suspending a flexible container, workers enter under the suspended load, which is a safety problem. Also, in the case where the bottom cover is removed, since the bottom cover is easily fixed, the discharge port part drops with the filler and the binding is removed by its own weight, so immediately after removing the bottom cover. In some cases, the filling material may be discharged, and the discharging position of the filling material may not be determined stably.

[0004]

[Means for Solving the Problems]

 The present invention has been made in view of the above points, and in order to solve the above problems, a velvet fastener is detachably attached to a bottom discharge port of a flexible container so that the discharge port can be opened and closed. The tape for opening / closing the discharge port attached to the flexible container is arranged so as to be bound, and one end side of the tape for opening / closing the discharge port is extended to be arranged on the side periphery of the flexible container. It is an object of the present invention to provide a safety flexible container characterized in that a belt for preventing the outlet from descending is attached to the bottom cover of the bottom portion and is openably and closably arranged on the bottom surface.

[0005]

[Action]

 According to the present invention, when the flexible container is hung to open the discharge port without placing it on the exclusive discharge rack, the end of the tape for opening and closing the discharge port at the side periphery is pulled, By removing the engagement of the velvet fastener attached to the binding side, the binding at the discharge port is released, and the filler can be discharged safely.

Further, the discharge port lowering prevention belt attached to the bottom cover of the bottom portion of the flexible container can prevent the above-mentioned discharge port portion from being lowered, so that the filler does not leak and the discharge port portion is prevented from leaking. The position can be stabilized and the filling material can be discharged to a predetermined position.

[0007]

【Example】

 Hereinafter, the present invention will be described based on embodiments. FIG. 1 and the following figures show one embodiment of the present invention. As shown in FIG. 1, the flexible container 1 is made of a synthetic resin or the like in a sturdy bag having a predetermined diameter and a predetermined length, and has an opening 3 on the upper surface thereof, which can be opened and closed by an opening tape 2, and an upper Kikuza seat. An upper chrysanthemum seat 5 and an upper chrysanthemum seat inner lid 6 which can be opened and closed by a tape 4 are provided, and a hanging loop 7 is attached to the upper peripheral portion for easy transportation.

On the bottom surface side of the flexible container 1, as shown in FIGS. 1 and 2, a cylindrical discharge port portion 8 having a predetermined length is disposed so as to be able to hang down, and its lower peripheral portion and the middle portion. The protrusions 9 and 10 of the rope are provided around the protrusions, respectively, and a tape 12 for opening and closing the discharge port, to which a velvet fastener 11 is attached, is attached between the protrusions 9 and 10 so that they can be bound. There is. By engaging and disengaging the velvet fastener 11, the outlet opening / closing tape 12 is bound to the outlet portion 8 or released. Then, the other end of the outlet opening / closing tape 12 is extended to the lower peripheral portion of the side portion of the flexible container 1, and the outlet opening / closing tape 12 is pulled from the side peripheral portion of the flexible container 1 to be discharged. The binding of the outlet portion 8 is released so that the filler can be discharged.

As shown in FIG. 2, a narrow cross-shaped reinforcing member 13 is sewn on the bottom surface of the flexible container 1, and one end thereof has a circular shape as shown in FIGS. One end of the bottom cover 14 is sewn on and reinforced so that the bottom part can be easily opened and closed by the reinforcing material 13 and velvet fasteners 15 and 16 arranged at appropriate positions on the bottom cover 14. There is.

As shown in FIG. 2, a discharge port lowering prevention belt 17 having a predetermined width is sewn on the central portion of the bottom cover 14, particularly the central portion in the opening / closing direction, and the cover binding string 18 is attached to the end portion thereof. The bottom cover 14 can be opened and closed as described above by attaching it to the other cover bundling string 19 attached to the opposite portion of the lower periphery of the flexible container 1. Reference numeral 20 is a body belt, and 21 is an unpacking string so that the ends of the tape 12 for opening / closing the outlet can be joined and held at the side peripheral portions.

Therefore, when discharging the filling from the flexible container 1 loaded with the predetermined filling as shown in FIG. 3, it is conveyed to a predetermined place by a crane or the like via the suspension rope 7. Then, the cover binding strings 18 and 19 at the lower peripheral portion of the flexible container 1 are released, the bottom cover 14 is opened as shown in FIG. 1, and the discharge port portion 8 appears. The discharge port 8 covering the bottom cover 14 is prevented from descending by the discharge port lowering prevention belt 17 of the bottom cover 14, so that the discharge port 8 is filled with the filling material. It does not descend due to the gravity of and the filler does not leak.

Then, when the unpacking string 21 on the lower side is unwound and the other end of the tape 12 for opening / closing the outlet is pulled, the engagement of the velvet fastener 11 attached to the one end is released. As shown in Fig. 1, the binding of the discharge port 8 is released, the discharge port 8 hangs downward and opens, and the filling material is discharged.

In this way, it is possible to prevent the filler from spontaneously leaking from the discharge port, and to open the discharge port at the side of the flexible container to safely discharge the filler to a predetermined position. can do.

In particular, since the protruding portion of the rope is provided at the discharge port, the tape for opening and closing the discharge port can be firmly attached without breaking the binding of the tape for opening and closing the discharge port during transportation or storage. It is a good thing to be united.

[0015]

[Effect of the device]

 As described above, according to the present invention, the discharge port at the bottom of the flexible container can be restrained by the belt for preventing the discharge port from descending on the bottom cover, and the filler naturally leaks from the discharge port due to its own weight. Can be prevented. In addition, the tape for opening and closing the discharge port, which is bound to the discharge port, can be pulled by the side of the flexible container to release the binding, and the discharge port can be opened, allowing the operator to flex as before. There is no need to enter below the container to perform opening work, and the filling material can be safely discharged into place.
