Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and an apparatus for manufacturing a sealed packaging bag in which two or more types of seasonings and the like are housed in the same packaging bag.

[Conventional technology]

BACKGROUND ART Today, simple packaging bags are widely used as seasonings for instant ramen noodles and the like, in which liquids such as seasoning liquid and oil or liquids and powders are separately stored in the same packaging bag. This is because it has advantages such as low packaging cost and low bulk. For example, in a bag of this type, a rectangular bag is provided with a parallel partition on the vertical edge as shown in Fig. 4, and the area defined by the partition is filled with liquid, etc. There is.

However, when two types of contents are taken out at the same time from the packaging bag of the form shown in FIG. 4, there is a problem that the bag is difficult to open because the distance to cut the bag becomes long.

This problem can be solved by making the packaging bag as shown in FIG. However, a packaging bag that separately accommodates two or more types of contents is usually as shown in Fig. 4, and is manufactured, for example, by the method described in Japanese Patent Publication No. 5'l-59127. If this method is applied as is to the packaging bag shown in FIG. 1, various problems will occur. That is, in the bag shown in FIG. 1, there is a diagonal seal part in the inner partition, so if this seal is formed with the first roll, one of the content storage areas will be formed here, and the content will not be filled. The nozzle must be installed above the first roll. In such a case,
Since it is not possible to fill the liquid, etc. until the above-mentioned content storage area is almost completed, the liquid, etc. to be filled can be filled into the packaging bag after the partition is sealed to the top of the packaging bag. The containment area must be filled within a short time before the top edge is sealed.

Therefore, since the filling liquid etc. must be discharged all at once from the nozzle for filling the contents, the liquid etc. may splash and splash outside or onto the sealing area, resulting in excess or deficiency in the amount of storage, or the sealing area may burn, reducing the product value. A problem arises in that the performance decreases.

On the other hand, if the above-mentioned filling time were to be extended, the rotation of the rolls would have to be slowed down in order to fill the bag without discharging the liquid all at once, which would cause a problem in that the productivity of the packaging bag would be reduced.

[Problem that the invention seeks to solve]

Therefore, an object of the present invention is to provide a manufacturing method and apparatus that can efficiently and easily manufacture a sealed packaging bag in which the partitions are concentrated at the corners of the packaging bag as shown in FIG. do. Another object of the present invention is to provide a method and apparatus for sealing contents that can easily fill different contents separately and store a uniform amount of contents.

[Means for solving problems]

The present invention is based on the knowledge that the above-mentioned problems can be effectively solved by forming a partition halfway along the longitudinal direction of a packaging bag sheet, and then forming a diagonal portion of the partition seal. It was done.

That is, in the present invention, a compartment-forming partition provided for separately accommodating two or more kinds of substances in the same sealed packaging bag extends from the upper edge of the packaging bag in the vertical direction. In a method for producing a sealed packaging bag formed by sealing up to a point and diagonally sealing from the point toward one of the corners at the lower edge of the packaging bag, the following steps are provided: ■: The packaging bag Step of sealing along the longitudinal direction of the forming sheet to form the partition partway; II: Sealing the lower edge of the packaging bag forming sheet and sealing the diagonal part of the partition to form the partition. III: Filling the compartments formed by the seals with the contents, and IV: Sealing the upper edge of the packaging bag forming sheet to seal the contents. Provided is a method for manufacturing a sealed packaging bag characterized by:

The continuous manufacturing method described above is performed using, for example, the following equipment. In other words, the compartment-forming partition provided to separate and accommodate two or more types of substances in the same sealed packaging bag is

This device includes a pair of sealing protrusions provided in the circumferential direction of the roll for sealing along the longitudinal direction of the packaging bag forming sheet sandwiched between the gaps 6 and forming the partition halfway. First roll: A sealing protrusion is provided on the peripheral wall of the roll for sandwiching the packaging bag forming sheet sent out from the first roll and sealing the diagonal part of the partition, the lower edge and the upper edge of the packaging bag. A sealed packaging bag, characterized in that a nozzle for filling the contents is disposed through a pair of second rolls and a recess formed in a non-projecting part between the first roll and the second roll. This is the manufacturing equipment.

In the present invention, the packaging bag forming sheet may be a cylindrical sheet with open upper and lower edges, a sheet in the form of one sheet folded into two along the longitudinal direction, or two sheets. It is possible to use one in the form of overlapping. When using a sheet formed by folding one sheet into two along the lengthwise direction, a seal-forming protrusion for sealing the released longitudinal edge is placed on the first roll. established in
Preferably, the longitudinal edges are sealed at the same time as the longitudinal partitions. On the other hand, even when two sheets are used, seal-forming protrusions are provided on the first roll to seal the edges that occur on both sides in the vertical direction, and at the same time as the partitions along the vertical direction, Preferably, the edges on both sides of the direction are sealed.

Hereinafter, details of the present invention will be specifically explained using the drawings.

As shown in FIG. 1, the sealed packaging bag l produced according to the present invention has 1. A compartment-forming partition 2 provided for separately accommodating two or more types of substances in the same packaging bag starts from one location on the lower edge 3 of the packaging bag 1 and extends in the longitudinal direction of the packaging bag 1. The packaging bag 1 is sealed along the packaging bag 1 up to a midway point 4, and from the location 4 toward one corner 5 of the packaging bag 1.

The above-mentioned packaging bag 1 may be in the form of one sheet folded and sealed at the open side edge, or in a stacked form such as two sheets with the open side edge sealed. Suitable materials for the sheet used here include polyolefin resins such as polypropylene and polyethylene, and thermoplastic resins such as nylon and polyester. or,
In order to improve the storage stability of the contents, a single film or laminate film made of polyvinylidene chloride, ethylene vinyl acetate copolymer, nylon, etc., or a laminated film of aluminum foil or the like as appropriate is also preferable. Furthermore, depending on the contents, cellophane or laminated paper may also be used. Moreover, at least one surface can be made transparent so that the contents can be seen through.

Further, the above-mentioned sealed packaging bag 1 accommodates a large number of things such as powder, liquid, paste, etc. Specifically, various combinations such as seasoning liquid such as soy sauce and oil, coffee concentrate and cream, or wasabi and soy sauce can be stored.

A method of manufacturing the above-mentioned sealed packaging bag 1 using a single sheet folded in the vertical direction as a packaging bag forming sheet will be explained with reference to FIGS. 1 to 3. First, the packaging bag of the forming sheet is sealed in the vertical direction. That is, the second

That is, by continuously repeating the above-described steps, the sealed packaging bag 1 can be efficiently manufactured, and productivity can also be improved.

Note that the above sealing is performed under known heat sealing conditions.

〔Effect of the invention〕

In the present invention, since the vertical and middle partitions of the packaging bag are sealed and formed in advance by the first roll, sufficient time can be taken for filling liquid, etc. in the next step. Therefore, there is no need to discharge the liquid etc. all at once from the filling nozzle, so it is possible to prevent the liquid etc. from scattering. Therefore, an even amount of liquid etc. can be filled into the packaging bag. Moreover, since the liquid and the like do not adhere to the sealed area, there is no possibility that liquid or the like is likely to burn at the sealed area after heat sealing and that the appearance of the packaging bag becomes poor. Such remarkable effects can be obtained.

Furthermore, a remarkable effect of improving the productivity of packaging bags can also be obtained.
