Description

[Detailed description of the invention]

(Technical M field) This invention is a flexible container for storing granular materials such as grains and chemical raw materials.
tl. Here, "J" refers to "I+" for inputting powder into a flexible container or ejecting powder from a flexible container. (Prior art) Flexible containers have the advantages of not being used (PI 11+), can be folded, does not take up much storage space, do not rust, are easy to maintain, etc.
Currently, it is widely used in various industries.

[1] It is formed from a rq flexible material net that is the same as or similar to the flexible material. When storing powder or granular material in a flexible container or discharging it one by one, a person must tie the granules with ropes, etc., or untie the ropes, etc. work is being carried out. This work is extremely tedious and must be carried out in an atmosphere filled with dust from the powder and granules, which is not good for the health of the workers. On the other hand, in a flexible container that stores powder and granular materials, the dumping date tied with a robe or the like protrudes from the flexible container, and this protrusion becomes an obstacle when viewing a large number of flexible containers. The reality is that there are. In other words, the protrusion of the discharge port bound by lobes or the like causes the flexible containers stacked in one level to tilt, making it difficult to stack the flexible containers in multiple levels. In addition, as mentioned above, conventional flexible container throwing JJI■ requires a worker to open and close it using a robe, etc., but it is now possible to automatically perform this work using a machine, etc. It is very difficult to do so. This is a 7 lexiple container whose main body and discharge port are 511
This is because it is made of an octane material. (Purpose) 1 unfired! J was created in view of the above-mentioned circumstances, and its 14 main points are that it maintains the advantages of conventional flexible containers of this type while making the opening/closing process easier and shorter. ('≧)) To minimize the protruding portion when closed. (2) To provide a chess slot that has a simple and light structure and can reduce manufacturing costs. That is, the gist of the present invention is as follows. Membrane force [A base material that constitutes the main part of the mouth and is made of a flexible material such as rubber or synthetic 4#l resin, and this film attached to this base material], (

The present invention includes a reinforcing material fixed to the base fabric located between the vertical fold line and the diagonal fold line. In other words, the present invention makes it possible to easily open and close the dumping port by pre-applying creases to the dumping port so that it can always be folded into a fixed shape. This is an attempt to minimize the protruding parts of the (Structure) Below, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a perspective view of a flexible container (10) equipped with a dumping port (20) according to the present invention. This flexible container (10) has a main body (II) formed into a bag shape from +i (flexible material) such as synthetic resin, and the outer periphery of this main body (11) is
A robe (12) is also included for use when hanging objects. In addition, cultivation ports (20) (20) are fixed to the first side and the bottom surface of the main body (11), respectively, and a plurality of cultivating bodies (13) are fixed around the cultivation ports (20).
- (13) are fixed so as to surround each inlet/outlet (20). A lobe (14) is inserted through the tip of each body (13), and each body (13) is closed by squeezing this lobe (I4). Each discharge port (20) has a cylindrical base material (21) formed of a flexible material such as rubber or synthetic resin, and this base material (21) as shown in FIGS. 3 to 6. ) between one end and the rigid wire (22) attached to the other end.

A reinforcement 71f (25) cut into a triangular shape from the same material as the base material (21) is attached to the part located between the double folds Ij (23) and (24) of 1). to partially increase the rigidity of the base material (21). In this case, each reinforcement 1I-f (25) is arranged so as not to interfere with each fold (23) (24). Next, the adhesion margin (21b) of the base material (21) is fixed to the base material (
21] The other end is fixed to make the base material (21) into a cylindrical shape. After that, as shown in FIG. 6, each rigid wire (22
) can be attached to both edges of the base material (21) using the screw (2]a). Each of these rigid wire rods (2

By folding the base material (21) along each of the fold lines (23) and (24), a shape as shown in FIG. 4 is obtained, 7ff. The stacking opening (20) is then entirely folded to give a final folded state. At this time, it is preferable to apply a release agent to the base A4 (21) and the reinforcing cloth (25) in advance so that they do not fuse together. After doing this, one end edge of the material (21) is attached or welded to the periphery of the opening of the main body (11) constituting the container (10), as shown in Figure t4'S6. By this, the flexible container (10) is thrown 4A.
[:+ (2o)]. In this way, each stack (20) is made of the same material as the main body (11) of the container (10, 1), without the need to form a rope for closing and a hole for passing it through. It can be formed using only wires 1 and piano wire, has a simple structure, and can reduce manufacturing costs. (Achievement of objective (2) of the present invention) (Operations and effects) Therefore, the following can be achieved. The stack p (20) configured as in 1- is used as follows. That is, on the stack p (20) on the second side of the container (10), the rigid wire (22
), the stacking opening (20) opens as shown in FIGS. 1 and 3 by slightly rotating and lifting the opening end formed in a circular shape. − force, the throw #Jll located at the bottom of the container (lO) +−+ (20
), if the opening end of the scraping port (20) is left free, the stack o (20) will open naturally due to its own weight. In this case, in each stack [j (20), a predetermined rigidity is imparted to the open end 1j by the rigid wire (22). As shown in Fig. fiS1, the container (10) has a circular opening and a hole for putting the powder into the container (10).
It can be easily connected to the outlet of a container or the input port of another container or container that stores powder or granular material. Also, if you want to close each box (20), 11.1-

In the eye (20), the base material (21) is folded in a certain direction.
The double-fold IJ (23) (24) is attached in advance so that it can be bent by 1, and the rigidity of the reinforcement 4i (25) allows the base material (21) to be folded inside (23) ( 24), so each stage is 4J.
tl r-+ (20) is always reliably folded into the state shown in the miniature in FIG. and. Each part of the folded material (21) intersects with each other to avoid gaps, and the contents of the container (10) do not leak out. In the opening and closing work of J5, each stage JE IJ (20), the opening II of each throw t41-port (20)
The rigid wire rod (22) on the edge side always holds the edge of each folded portion of the base material (21) in a fixed position. Therefore, each part of the material (21) to be folded is not randomly folded (folded), but is neatly folded (11 folded) while being held in a predetermined position by the rigid wire (22). −ζ・Each stage JJ) r−+

Therefore, when stacking a large number of containers (10), it is possible to stack them in an orderly manner compared to the conventional method of closing them with ropes, etc. It is i). As a result, the stacking work can be done easily and within a short period of time without having to worry about tilting the containers. CObjective of the present inventiont? ) Achievement of the above-mentioned steps (20) according to the present invention are not closed by binding with a conventional robe etc. Since it can be easily closed using the restoring force of the ball, it does not necessarily require human work and can promote mechanization more than the conventional throwing and hitting 111. be. Furthermore, the stack n (20) according to the present invention can be simply attached to the main body (11) of the flexible container (lO) as it is, so the stack n (20) of the flexible container that has already been used in the past can be By attaching it in place of the container, it is possible to easily improve a flexible container that is already out of use into a one-ton container. In addition, in the example described in -1-1, an example was explained in which the number of double folds l:l (23) and (24) on the stacking date (20) was set to 6 trees, respectively, or these double folds (23) (
The number of items 24) may be changed accordingly. In this case, there is no problem with vertical folds I'' (23) just by making them at equal intervals of 4 = j, but for j, + folds [1 (24), between each vertical fold (23) The distance between and the length t of the opening (20) must be 14', 1° to ensure the diagonal angle of each longitudinal fold [, + (23)].
