Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a packaging bag for powder and granular materials used when transporting powder and granular materials such as feed.

[Conventional technology]

Conventionally, packaging bags as shown in FIG. 8 have been used to transport feed for livestock such as chickens, cows, and pigs. In FIG. 8, reference numeral 1 is a bag body, and the bag body 1 has an inlet 2 at the top and an outlet 3 at the bottom.
is formed. The inlet 2 and the outlet 3 are provided with binding cords 4 and 5, respectively. Moreover, external lids 6 and 7 are provided on the outside of the inlet 2 and the outlet 3, respectively, and these external lids 6 and 7 are provided with drawstrings 8 and 9 and sliders 10 and 11, respectively. .

In addition, on the injection port 2 side of the bag body 1, suspension belts 13...13 are fixed at four locations via suspension cloths 12...12, and these adjacent suspension belts 13, 1
Hanging ropes 14, 14 are installed between the three.
In addition, the reference numeral 15 is a reverse pulling reinforcing belt 15 when the hanging rope 14 is pulled in the opposite direction.

To transport feed using such a packaging bag, first, at a feed company, etc., tie the outlet 3 with a string 5 and leave the inlet 2 open, and after filling feed from the inlet 2. Bind the inlet 2 with a string 4. In this state, it is hoisted up via the hanging ropes 14, 14, loaded onto a truck, and transported to a farm or the like.

The packaging bag transported to the ranch is hung on a hanging rope 14,
14 and placed at the entrance of a silo or the like, the cord 5 is untied, the discharge port 3 is opened, and the feed is sent in. The packaging bag emptied after discharging the contained feed is sent back to the feed company, the outlet 3 is tied again, the inlet 2 is opened, and then the bag is filled with feed.

[Problems to be solved by the invention] However, with such packaging bags, it is necessary to open the inlet 2 and tie the outlet 3 of the returned packaging bag, and these operations are troublesome. It was extremely time consuming. Particularly in the winter when the temperature drops, packaging bags made of synthetic resin become hard, making workability even worse. In addition, feed may be sent back with residual feed remaining in the binding part of the injection port, and when the returned packaging bag is used as a packaging bag for feed for other animals, the remaining feed from the other animal may be left behind. Contaminants were sometimes mixed into animal feed. Furthermore, when stored in the open for a long period of time, the upward facing injection port 2 side becomes depressed.
Water accumulated in this area and mold grew.

In addition, as a solution to the problem of packaging bags with separate injection and discharge ports, there has been developed a packaging bag with only one injection and discharge port, which also functions as an injection and discharge port. . This packaging bag was provided with a cylindrical air vent that could be opened and closed with a string near the inlet/outlet for stability and workability when stacked.

However, this packaging bag has not been put into practical use because feed remains in the air vent, and removing the remaining feed becomes troublesome.

The object of the present invention is to solve the above problems and provide a packaging bag for powder and granular materials with extremely good workability.

[Means for solving problems]

The present invention has been made to achieve the above object, and includes a bag body that accommodates powder and granules, an inlet and outlet formed in the bag body and through which the powder and granules are injected or discharged.
A binding means for binding the inlet and outlet, a hanging rope provided on the opposite side of the bag body from the inlet and outlet, and an air chamber provided on the outer surface of the bag body to form an air chamber between the bag body and the bag body. forming means; a first air venting means formed of a hole formed in the bag body and communicating the inside of the bag body with the air chamber; and a first air venting means formed in the air chamber forming means and communicating the air chamber to the outside. This packaging bag for powder or granular material is characterized in that it is equipped with a second air venting means consisting of a hole that allows the air to escape.

The bag body is for storing powder and granular materials,
An inlet/outlet is formed in this bag body. This inlet/outlet is used for injecting powder or granules from a hopper etc.
This is for discharging powdered materials such as feed to the transport port of a silo, etc.

The binding means is for binding the inlet/outlet to prevent the contained powder from leaking to the outside.
Rope if it can be sealed with some degree of waterproofness,
It can be bound in various ways such as fasteners.

The lifting rope is provided on the side opposite to the inlet/outlet when the lifting rope is used to lift a packaging bag for discharging powder or loading onto a truck. It is preferable that the hanging ropes be fixed at four locations on the bag body and provided in a cross shape, since this facilitates work during slinging and powder filling.

The air chamber forming means is for forming an air chamber interposed between the first air venting means and the second air venting means, and may also be used as a member for connecting the hanging rope to the bag body. .

The first air bleed means and the second air bleed means are
It is for discharging the air inside the bag body to the outside, and may have any size or shape that does not allow powder or granular material to easily pass through, such as a slit shape or a circular shape. The first air bleed means and the second air bleed means are preferably formed of a hard material around the periphery, and are preferably double-layered with their outer sides covered. Moreover, the position and number of air vent holes can be set arbitrarily.

The packaging bag for powder and granular materials of the present invention is used for feed for livestock animals such as cows and pigs, as well as fertilizers, industrial chemicals, foods, limestone, etc.

[Effect]

In the packaging bag for powder and granular material of the present invention, the bag body accommodates the powder and the granular material is injected into the interior through the injection and outlet by tying or opening the inlet and outlet using the binding means, and Or discharge the powder to the outside through the inlet and outlet. The hanging rope is pulled so that it can be moved freely with the inlet and outlet facing downward. The first air bleed means and the second air bleed means release air from the bag body to the outside, thereby preventing the powder and granular material within the bag body from moving, thereby improving stability.

That is, the air inside the bag body flows into the air chamber formed by the air chamber forming means through the first air bleed means, and is discharged from this air chamber to the outside through the second air bleed means.
