Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging bag, and more particularly to a packaging bag in which two or more types of powders, liquids, solids and the like are packaged as a set and two or more bags are connected.

[0002]

2. Description of the Related Art Conventionally, as a packaging bag in which two or more bags are connected, for example, a long tubular film is heat-sealed at a predetermined length in the length direction, and some heat-sealed positions are skipped. The packaging bag 40, in which several bags are connected as shown in FIGS. In such a packaging bag 40, several bag bodies 41 are connected in the vertical direction by heat seals 41, and the shape thereof is relatively long in the vertical direction and its handling and utilization method is also limited. There is a limit to what can be packaged in such a packaging bag, and there has been a problem that it is difficult to separately package different kinds of liquid substances and the like at the same time.

[0003]

SUMMARY OF THE INVENTION The object of the present invention is to solve the above-mentioned problems by, for example, being able to separately pack a plurality of liquid substances at the same time and separately package them. An object of the present invention is to provide a vertical double-row packaging bag that enables the same, and further to provide a manufacturing method capable of continuously producing the same packaging bag.

[0004]

A vertical double-row packaging bag according to the present invention comprises a long strip-shaped film, both side edges of which are folded, and at least both side edges are superposed on the body material film in a butt-like shape, adhered, and bonded to each other. It is characterized in that it is cut into a predetermined length in the direction and the bottom is heat-sealed.

A method for manufacturing a vertical double-row packaging bag according to the present invention is a method for producing a folded packaging bag in which both side edges of a long strip-shaped film are aligned with a width-determining plate, and at least 1 is provided at a front end of the width-determining plate. It is characterized in that individual cutout recesses are provided, an adhesive agent supply nozzle is provided in the recesses, and both side edges are abutted at the position of the cutout recesses and polymerized and bonded on the body material film.

[0006]

As shown in FIGS. 1 and 4, the vertical double-row packaging bag according to the present invention is a rigid packaging bag having a plurality of laterally-arranged packaging bags and an opening at the top. It becomes possible to put things in bags and package them. What is packaged is not limited to a liquid material, and any material such as powder, granules and small articles that can be put in a bag can be applied.

In the method for manufacturing a vertical double-row packaging bag according to the present invention, since the long strip-shaped film is continuously drawn out, both side edges are bent, and at least both side edges are polymerized and adhered to each other in a butt-like manner, It is possible to continuously create a plurality of vertical packaging bags.

[0008]

The present invention will be described in detail with reference to the drawings. Figure 1
[Fig. 3] is a perspective view of two vertical packaging bags 1 in series. The vertical packaging bag 1 comprises a bag body 1a and a bag body 1b.
As for b, both side edges 6b and 6c of the long strip-shaped film 6 of one school are bent, and are polymerized on the body material film 6a and the adhesive 3
It is formed by being adhered by. Further, the bags 1a and 1b are cut into a predetermined length in the length direction, and the bottom portion is heat-sealed 4 to form the two vertical packaging bags 1.

FIG. 2 is a side view showing the construction of a specific embodiment of the manufacturing method for producing the two vertical packaging bags 1, and FIG. 3 is an enlarged explanatory view of the main parts thereof. The long strip-shaped film 6 is pulled out from the roll body 10 via the guide rolls 11, and the width-determining plate 13 arranged on the table 12.
Both side edges 6b and 6c are bent along and are superposed on the body material film 6a. Cylindrical guide bars 14, 14
Guides the bending of both side edges 6b and 6c, and the pressing rolls 15 and 15 hold the bent both side edges 6b and 6c and guide the width determining plate 13 sufficiently.
The guide bar 14 and the presser roll 15 may be increased in number as necessary, and the mounting angle position and the like may be adjusted and arranged. Both side edges 6b, 6c that are bent are superposed on the body material film 6a in a butt shape.

The width determining plate 13 has a rear end formed in a triangular shape, and at least one notch recess 13a is provided at the front end (see FIG. 3). Here, the front is the traveling direction of the long strip film 6. An opening pin 16 is arranged at a position close to the rear end of the notch recess 13a, and both side ends 6b and 6c of the long strip film 6 which is once superposed in a butt shape are opened, and the adhesive nozzle 17 is provided. Thus, the adhesive 4 is applied to the body material film 6a.

The adhesive nozzle 17 is arranged in the cutout recess 13a, and a small piece such as felt is provided at the tip of the nozzle 17 to apply the adhesive 4 like brush painting.
A pressing plate 18 is provided in front of the adhesion nozzle 17, and presses the adhesive 4 to stabilize the adhesion. A stable pressing force is applied to the holding plate 18 by a balance weight 20 via a fulcrum 19.

The pair of nip rolls 21 are bags 1a, 1
Since b is wound in a stable state, it is provided for folding into a flat shape and may be provided as needed. That is, instead of being wound at the same time as bonding, a packaging bag may be created by cutting directly in the length direction and heat-sealing, but in order to automate the packaging process of the next step, it is wound on a roll body. Is desirable. Then, in the packaging process, the bag 1a,
It is also possible to create a packaging bag while continuously pulling out 1b and package the contents at the same time.

FIGS. 4 and 5 show three continuous vertical packaging bags 20,
The principal part explanatory drawing of the Example of the manufacturing method is shown. The three continuous vertical packaging bag 20 comprises bags 20a, 20b, 20c, and the bags 20a, 20b, 20c are long strip-shaped films 26.
Both side edges 26b and 26c are folded to have a width dimension of 1: 2 and are superposed in a butt-like manner on the body material film 26a and adhered to each other, and a width dimension of one side edge 26c is further divided into 1: 1 at a position 26d. It is formed by being polymerized on the body material film 26e and adhered by the adhesive 5.

At this time, at the front end of the width determining plate 38,
Notch recesses 38a and 38b are provided, and the adhesive 33 is applied to the recess 38a by the nozzle 37a.
At 8b, the adhesive 35 is applied by the nozzle 37b.
The nozzles 37a and 37b have the same structure as the adhesive nozzle 17, and apply the adhesives 33 and 35 thereto. Notch recess 38b
As shown in FIG. 5, it is desirable to extend the nozzle to a position where the nozzle 37b can be easily arranged.

The present invention is not limited to two or three stations, but any number of stations can be applied, and it is possible if consideration is given to a guide for bending, a cutout recess, and the like.

The long strip film applied to the present invention is
Any film can be used as long as it can be adhered with a solvent type adhesive, and examples thereof include polyvinyl chloride, polyethylene, polyolefin, polystyrene and polyamide.
