Description

[Detailed explanation of the invention] Conventionally, a discharge tube was provided at the bottom of a container bag, and the bottom of the bag was provided in a conical shape.
Many container bags having a structure for discharging stored items are known. However, if a structure that can be discharged is provided, the cutting and sewing of the fabric will be more complicated than with a container bag that simply has a closed bottom, and it will take time and effort to manufacture it, making it difficult to manufacture it efficiently. It required skill.

Therefore, an object of the present invention is to provide a container bag which has a discharge structure at the bottom and is formed into a rectangular cylindrical shape, and which has a simple structure and can be easily manufactured.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention will be explained below according to the embodiments shown in the drawings.

FIG. 1 is a perspective view showing the assembly process of the bottom of the container bag according to the embodiment of the present invention. First, the main body 1 made of flexible fabric is formed into a flat cylindrical body.
A notch 3 is provided at the center of the side edge 2, and notches 4 are provided on both sides of the notch 3.

As shown in FIG. 2, the notches 4 are provided at predetermined lengths 2a-2c and 2b-2d from both ends 2a and 2b of the side edge 2, narrowing the notch 3 and being symmetrical on both sides. There is.

In the example, the length of the cut 4 is 2a-2
slightly longer than the length of c or 2b-2d, 2c-
The length of 2d is twice the length of 2a-2c or 2b-2d.

Moreover, although the cutout part 3 is cut out in a circular shape to match the outer periphery of the discharge tube 9, the cutout part 3 may be simply provided by a notch as shown in FIG. 2B.

If the cutout portion 3 and the notch 4 are provided in the state where the main body 1 is formed into a flat cylindrical body in this way, the cutout portion 3 and the notch 4 that face each other will be provided on the side edge 2.

Next, if you assemble the corner of the square bag on the extension line of the notch 4 provided in this way, the first
As shown in Figure B, two pairs of opposing opening pieces 5 and 6
A rectangular cylinder having 7 and 8 is formed. By bending a set of the opening pieces 5, 6, 6, 7, and 8 provided with the cutout portion 3 inward, the rectangular cylindrical main body 1 is formed as shown in FIG. 1C. form the bottom. At this time, since the length of the notch 4 is long as described above, 5b and 6b of the opening pieces 5 and 6 are
The added length is longer than the length of 7a or 8a of the opening pieces 7, 8, and when the opening pieces 5, 6 are bent inward, the side edges 5a and 6a overlap, and in this overlapping part, the opening piece 5 and Join 6. Furthermore, the opening piece 5,
The portions 5b and 6b where 6 contacts the opening pieces 7 and 8 are joined.

Next, the discharge tube 9 that fits into the hole formed by the notch 3 is joined. The discharge tube 9 is formed into a cylindrical body as shown in FIG. 3, and 16 indicates a joint portion when forming the cylindrical body. One end of the cylinder is cut in several places to form several pieces 15, and these parts are brought into contact with the insides of opening pieces 5 and 6 having cutouts 3 on the bottom surface of the main body 1 to be joined.

FIG. 4 is a bottom view of the main body 1 formed into a rectangular cylindrical shape, showing the locations 10 to be joined. That is, the overlapping portion 13 of the side edges of the opening pieces 5 and 6, the outer periphery 14 of the hole formed by the cutout 3, and the opening piece 7,
8 and the opening pieces 5, 6 are provided along the contact portions 11, 12. The joint can be made by sewing or welding, but in the case of sewing, all the parts can be made by sewing on the outside, making the sewing work easy and efficient.

5 to 7 show examples of the bottom structure of the main body 1. FIG.

17 is a binding tape that closes the discharge pipe 9, 18,1
9 and 20 are tapes for closing the bottom of the main body 1 as a lid with the opening pieces 7 and 8, and 21, 22, 23, 2
4 and 25 are slits through which the tapes 18, 19, and 20 are passed. The tapes 18 and 20 are joined to the opening pieces 6 and 5 forming the bottom surface, and the tape 19 is joined to the opening piece 7 at 31, 32 and 33, respectively. As shown in FIG. 7, the tape and slit thus provided are structured so that the opening pieces 7 and 8 cover the bottom of the main body 1, and the tape is brought out through the slit and tied up to close it.

In this way, the opening pieces 7 and 8 are structured to close and cover the entire discharge tube at the bottom of the main body, so even if the main body is dragged one by one when transferring to the cargo bed of a vehicle, etc. The cylinder is protected and cannot be damaged. In addition, the bottom surface is square,
This prevents the main body from falling when placed.

FIG. 8 shows an embodiment of the upper structure which is the injection port of the main body 1. 8A is provided with an inlet 29 that has the same inner diameter as the main body 1 and extends to the upper end, and FIG. 8B is provided with a cylindrical body 30 similar to the discharge pipe provided at the bottom of the main body 1. be.

28 is a binding tape for closing the injection port 29 or the cylinder body 30, and 26 is a belt for suspending the main body 1, which is connected between the main bodies 1 and 34. Reference numeral 27 denotes an auxiliary belt whose both ends are wound around and connected to the hanging belt 26, respectively.

The present invention having the above-mentioned configuration includes a flat cylinder having a notch on the side edge for attaching the discharge pipe, and a notch at a predetermined distance from both ends of the side edge. The extension line is used as the corner of the square bag to form a rectangular cylinder shape having two sets of opposing opening pieces, and the pair of opening pieces facing each other having the cutout part is bent inward to make a heavy bag. The side edge portion of the bent opening piece and the part that contacts the adjacent opening piece are joined to form the bottom surface of the square bag, and a discharge tube that fits into the cutout is further joined to form another set of opposing opening pieces. The square bag is characterized in that it has a lid at the bottom.

According to the present invention, since the notches are provided in the flat cylindrical body, the square cylindrical body can be manufactured with several cuts, and the joints when assembled into the square cylindrical body are one set with cutouts. It is only necessary to join the opening piece along the outer periphery of the opening piece, and there is no need to create an extra part of the fabric for assembly, so the structure is simple and easy to manufacture.
