Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a flexible container having a structure in which a discharge tube is provided at the bottom of the flexible container body and the contents are discharged from the discharge tube.

Conventionally, flexible containers for storing and transporting contents such as powder and granular materials have been shaped like cylinders, with an opening for filling at the top and a discharge tube for discharging at the outer bottom. have.

When storing contents such as powder or granular material inside the flexible container, a string is wrapped around the discharge tube and tied, and the contents are introduced through the filling opening with the opening of the discharge tube closed. It has various configurations.

However, with the above configuration, the discharge tube is simply tied with a string wrapped around it, so during storage and transportation, the weight of several tons of contents is applied to the string, causing it to loosen, causing the contents to leak out. This is often the case.

In particular, if the contents are ultrafine powder or water-containing substances, even the slightest loosening of the string may cause the ultrafine powder or water to leak out, and if this leakage occurs, There are problems that impede storage and transportation, which are the functions of containers.

In addition, in order to discharge the contents inside the container, the worker must crawl under the container and untie the aforementioned string, and at this time, a large amount of contents, weighing several tons, are suddenly released from the discharge tube. This exposes workers to extremely large risks and poses safety issues.

Moreover, in order to prevent the leakage mentioned above, the strings are tied very tightly, but when tied so tightly, the work required to untie them becomes more troublesome, and the worker is therefore exposed to more danger when discharging. There is.

The present invention was developed under such circumstances, and its purpose is to reliably prevent the leakage of contents within a flexible container, especially the leakage of water when the contents are in a water-containing state. Moreover, the purpose is to provide a flexible container that can greatly improve worker safety.

Hereinafter, the present invention will be explained according to the embodiments shown in the drawings.

First, in Figs. 1 and 2, reference numeral 1 denotes a flexible container body made in a cylindrical shape from a material sheet having flexibility, in which the surface of polyester fabric is coated with a synthetic resin. At the outer bottom of the cylindrical part, a discharge tube 2 is made of a sheet of material similar to that of the container main body 1 and extends to have flexibility, and at the top of the cylindrical part there is a filling opening (not shown). figure)
It has an imposing shape.

Reference numeral 3 denotes a locking belt having a tongue plate 4 at its tip 3a, and by fusing a round patch 5 provided at the base end 3b to the discharge tube 2, the locking belt 3 is attached to the discharge tube 2.
It is attached to the top.

Next, 6 is a buckle for releasably locking the tongue plate 4, which has a belt short piece 7, and by fusing a round patch 8 tied to this belt short piece 7 to the discharge pipe 2, etc.
The buckle 6 is attached to the upper part of the discharge pipe 2 so as to be located on the side facing the locking belt 3.

Here, the buckle 6 and the tongue plate 4 will be further explained with reference to FIGS. 4 to 7.
Regarding the buckle 6, 9 is a buckle base having a substantially U-shape having an upright plate 9a, 10 is a buckle bottom plate extending from the buckle base 9, 11 is a belt short piece 7 insertion hole formed in an elongated shape in the buckle bottom plate 10, Reference numeral 12 denotes a locking hole formed in the buckle base 9, 13 a front half piece located next to the locking hole 12 and protruding from the buckle base 9, and 14 formed so as to face the standing plate 9a at both ends of the bottom half piece 13. It is a protrusion.

Reference numeral 15 denotes a buckle cover which is rotatable up and down, that is, in the direction of arrow A, by being pivoted to the standing plate 9a of the buckle base 9 via a pin 16; 17, the standing plate 1 of the buckle cover 15;
The stopper hole 18 formed in 5a is a belt stopper pin provided at the tip of the buckle cover 15, that is, at the end opposite to the pivot.

Further, regarding the tank plate 4, 19 is an elongated belt insertion hole through which the locking belt 3 is passed, 20 is a locking protrusion whose tip is slightly bent downward, and 21 is a part of a stopper.

In order to lock the tongue plate 4 to the buckle 6, the locking protrusion of the tongue plate 4 is pressed while the buckle cover 15 is rotated upward as shown in FIGS. 4 and 5. 20 side in the direction of arrow B until the stopper part 21 comes into contact with the standing plate 9a as shown in FIG. 6, and the locking protrusion 20 is locked in the locking hole 12.

In this state, when the buckle cover 15 is rotated downward as shown in FIG.
5, the half piece 13 is pressed in the direction of the arrow C shown in FIG. and is locked.

In this locked state, no matter how much you try to pull the tongue plate 4 out, it will not come out.

On the other hand, to unlock this lock, please use the buckle cover 1.
5 is rotated upward, the elasticity of the half piece 13 causes the stop hole 17 to disengage from the protrusion 14, and the lock is immediately released.

In FIG. 1, reference numeral 22 indicates a cover attachment belt attached to the outer peripheral surface of the flexible container main body 1 in a hanging state, and 23 indicates a cover attachment buckle provided at the tip of the belt 22.

Furthermore, in FIGS. 8 and 9, 24 is a cover having a substantially circular shape, and has a predetermined extending portion 25 on the periphery.

26 is a belt that is passed over the cover 24 in a cross shape, 27
is a tongue plate for attaching a cover provided at the tip of the belt 26.

Next, to explain the operation, first, as shown in FIG. 2, the entire discharge tube 2 and the lower part of the flexible container body 1 are folded up.

Next, as shown in FIG. 3, the discharge tube 2 is rolled up in multiple layers from the lower end to the base end 3b of the locking bell (3) to form the rolled up part 28. is covered and fixed by the locking belt 3, and furthermore, the tongue plate 4 is inserted into the buckle 6 as described above and locked, thereby fixing the winding part 28 to prevent it from unraveling.

Thereafter, with the flexible container main body 1 hanging down as shown in FIG. 1, contents such as water-containing powder or granular material are introduced into the container main body 1 through the above-mentioned filling opening.

Then, as shown in FIG. 1, the flexible container main body 1 inflates, and the discharge pipe 2 and the roll-up portion 28 come to function as the bottom of the flexible container main body 1.

Next, attach the cover mounting tongue plate 27 to the buckle 2.
3, the cover 24 is attached to the flexible container main body 1 as shown in FIG. 8, and covers the second volume 28 to improve its appearance.

Now, in this embodiment, when the contents are put into the flexible container main body 1, the roll-up part 28 and the discharge tube 2 play the role of the bottom of the flexible container main body 1, as described above. The weight of several tons of contents is applied to the rolled up part 28, causing the rolled up part 28 to collapse in the vertical direction as shown in Figure 1, and its flexibility, that is, the flexible material sheets, come into close contact with each other. , to seal the discharge tube 2.

This prevents the contents from leaking.

Furthermore, since the winding portion 28 is rolled up many times as described above, it is sealed in as many layers as the number of times it is rolled up, and the above-mentioned leakage prevention effect is ensured. .

As a result, unlike in the past, no leakage occurs even if the contents are extremely fine particles or water-containing materials.

Furthermore, in the conventional method of simply wrapping and tying the discharge tube with a string, there is a problem that the greater the weight of the contents, the more likely the string is to loosen, increasing the risk of leakage.

In this respect, this embodiment has the advantage that the greater the weight of the contents, the more tightly the material sheets I of the flexible container main body 1 come into close contact with each other, making the sealing that much more stringent.

Furthermore, when discharging the contents, if the operating belt 29 is passed through the belt fixing pin 18 of the buckle cover 15 of the buckle 6 as shown in FIGS. 6 and 7, one end of the operating belt 29 The buckle cover 15 can be easily rotated by an operator simply pulling it from a distance, thereby unlocking the buckle 6 and the tongue plate 4.

Once the lock is unlocked in this way, the opening of the discharge tube 2 will open naturally depending on the weight of the contents, and the contents will be discharged.

Therefore, in this embodiment, the discharge tube 2 can be opened extremely easily by remote control using the operating belt 29.

Since remote control can be performed in one step in this manner, there is no problem of the operator being exposed to great danger by crawling under the flexible container main body 1 to untie the strings, unlike in the conventional case.

In addition, the ejection tube 2 is not folded in a random manner, but rolled up in a regular manner.
Another advantage is that the discharge tube 2 and the flexible container body 1 can be easily restored to their original states.

Moreover, although it has many excellent effects as explained above, in addition to the ejection tube 2, which has been conventionally used for tying with a string, the structure includes a locking belt 3, a buckle 6, etc. It also has the advantage that it requires only an extremely simple configuration.

In the above embodiment, the material of the flexible container main body 1 is a polyester fabric coated with synthetic resin on the surface, but it is not limited to this, and in short, any material having flexibility can be used. Bye.

In addition, the present invention is not limited to the embodiments described above and shown in the drawings; for example, the content is not limited to extremely fine powder or granules or those in a water-containing state, but can be widely applied to ordinary powder or granules. Of course.

As explained above, the present invention has a structure in which the discharge tube itself is attached to the top of the discharge tube itself, which extends to the outer bottom of the cylindrical part of the flexible container body.
A locking belt with a tongue plate at the tip is attached, and a buckle for releasably locking the tongue plate is attached to the upper part of the discharge tube itself on the side opposite to the locking belt, and the discharge tube is attached to the lower end. Roll it up into a nori roll shape from the beginning,
This roll-up part is covered and fixed by the locking belt, and the tongue plate has a bottom structure that is locked to the buckle. This allows a simple structure to prevent leakage of the contents within the flexible container body. It has excellent effects, such as being able to reliably prevent water leakage, especially when the contents are in a water-containing state, and also being able to open the discharge tube by remote control, making it much safer for workers. We can provide flexible containers.
