BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container bag for encapsulating and transporting a soil stabilizer, lime, cement, fertilizer, etc. More specifically, it is a one-way flexible container bag of about 300 to 1500 kg. The present invention relates to a container bag for carrying a relatively large amount of contents.

[0002]

2. Description of the Related Art The above container bag is 1750 denier.
The tetoron fibers of about 10 mils are woven and knitted, the guide part a is provided on the head, the cylindrical body part b is arranged in the middle, the bottom face c is arranged on the lower end, and they are sewn together by a sewing machine or the like. However, the seam d is in contact with the ground. Therefore, if the bag filled with the contents is placed on the ground as it is, the water will pass through the pores of the seam between the bottom surface and the body part after rain or when the ground is wet with night dew. Permeates into. As a result, if the filled contents are soil stabilizers, lime, cement, fertilizers, etc., they will absorb the moisture, the soil stabilizers will be altered, and lime will generate heat and become hydroxides. Change and cause serious problems in quality such as cement hardening In that case, if you place it in a dry place on the ground such as indoors, there is no problem, but as mentioned above, the one-way flexible container bag, Since the space is kept in a bag having a relatively large capacity of about 300 to 1500 kg, when the number is large, it is necessary to place the bag not only indoors but also outdoors.

[0003]

Therefore, the present invention is intended to obtain a container bag that is not adversely affected by the moisture of the ground even when it is left on the ground as it is indoors or outdoors.

[0004]

[Means for solving the problems] The container bag of the present invention is
In a container bag in which a body portion and a bottom surface are sewn together to form a tubular bag, at least the material of the bottom surface is made of water-repellent fiber, and the seam between the body portion and the bottom surface is at least 20 mm or more from the grounding surface. It is characterized by being formed at a height that does not allow water to penetrate from the ground.

[0005]

Since the container of the present invention has at least the bottom surface made of water-repellent fiber, it repels moisture and suppresses the action of osmotic pressure that rises from the ground to permeate and prevents moisture from entering. Furthermore, since the seam is formed at a height of at least 20 mm or more above the ground contact surface so that moisture from the ground does not penetrate, even if osmotic pressure acts, gravity reacts and moisture contained in the ground is absorbed. Prevent the penetration of.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Explaining an embodiment of the present invention, in FIG. 1, 1 is a so-called one-way flexible container bag, which is a container suitable for efficiently transporting a relatively large capacity of about 300 to 1500 kg. In the back, the head is provided with an inverted conical guide part 2 with a slight constriction toward the upper part, and the body part 3 formed endlessly with a folding diameter of 1700 mm and a height of about 1000 mm is provided on the lower part. The bottom surface 4 described later is continuously provided at the lower end.

The material is a polypropylene fiber in which at least the bottom face 4 is woven and knitted with a density of 15.times.15 single filaments of 1500 denier, for example, and a water repellent fiber obtained by laminating is applied. Of course, it is desirable that the body portion 3 and the guide portion 2 are also water-repellent fibers, but the fibers may not necessarily be used in consideration of the type of contents and economy.

The seam 5 for sewing the body 3 and the bottom surface 4 to each other is set at a height of at least 20 mm or more, preferably 50 mm or more from the ground, and moisture from the ground causes pores in the seam. Maintain a height that does not penetrate through. Specifically, the sewing is performed by cutting a circular bottom surface fabric fiber into a diameter larger than the diameter of the body portion, and folding back each other at a portion protruding from the diameter of the body portion to form a double tack portion 4a. The rising wall is formed so that its diameter is the same as that of the body. Then, the rising wall and the body are joined and sewn twice with a water-repellent thread by a sewing machine, and tightly sew each other (FIG. 2).
reference).

Next, the operation of this embodiment will be described. First, the container bag of the present invention is filled with a content which may be adversely affected by moisture such as soil stabilizer or lime, cement, etc. A case will be described in which the guide part is bound and the input port is closed, and it is placed outdoors. When it is placed outdoors, not only when it rains and the ground contains a lot of water, but also when the dew drops in the summer and frost in the winter, when the ground contains water, The water penetrates the inside of the bag through the pores of the seam, and if the content is a dried powder or granule, the water is absorbed more and more by the osmotic pressure action.

However, since at least the bottom surface 4 of the container of the present invention is made of water-repellent fiber, it can repel water and suppress the action of the osmotic pressure that rises from the ground to penetrate. It is possible to prevent water from entering. Furthermore, the seam 5 is at least 20 mm from the ground contact surface.
As described above, since it is preferably formed at a height of 50 mm or more so that water from the ground does not permeate, even if osmotic pressure acts, gravity acts to counteract the permeation of water contained in the ground, Prevent intrusion.

At this time, the double-folded tack portion 4a can buffer the burst pressure due to the weight of the contents filled in the bag with a double structure to increase the strength of the bag bottom portion.

[0012]

[Effect of the Invention] The container bag of the present invention based on the above construction can prevent moisture from penetrating from the ground even outdoors, so that contents such as soil stabilizers are adversely affected by moisture, such as alteration. However, it also has an excellent effect that the quality can be protected, and at that time, it does not require a special instrument or device, which is economical. In addition, even when the bottom surface is torn and the contents are taken out after the conveyance, the shape of the bottom surface has a deeper roundness than the conventional one, and therefore the taking out becomes easy.
