Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to beverages such as sports drinks and fruit juices, seasonings such as alcoholic beverages, sauces and dressings, various liquids such as shampoos, lotions and liquid detergents, and liquid materials having viscosity. The present invention relates to a method for producing a bag-like container with a plug which is optimal for filling the contents of the above.

[0002]

2. Description of the Related Art Conventionally, for example, a self-standing container called a standing pouch is known as a bag-shaped container made of a sheet. Such containers are used for filling contents such as various liquids such as sports drinks and fruit drinks.

The container has a container body 40 made of a flexible sheet as shown in FIG. 6, and a spout 41 for taking out the liquid filled in the container body 40.
The container main body 40 has a pair of left and right side walls 43, 43 and a bent gusset-shaped bottom 44. The plug 41 heats the upper edges 43a of the side walls 43, 43 in a flat shape. It is attached to the upper edge by sealing.

[0004] In addition, campaigns, such as various kinds of prizes, are frequently carried out on products in which the beverages and the like are filled in containers, in the case of such campaigns. An application sticker (label) on which a dedicated display is printed is attached to the side wall 43 of the container body 40. In addition, besides the application seal, a label such as a glossy label subjected to hologram processing for improving the visibility of the product may be separately attached to the surface of the container.

[0005]

[Problems to be solved by the invention]

At the time of applying the label, the operator attaches the label to the container body 40 after the bag is made. The container body 40 is made of a flexible sheet. Since the beverage or the like is filled, the beverage is deformed and becomes unstable, making it difficult to attach a label, resulting in poor workability. In addition, since the plug 41 is attached to the upper edge of the container body 40, the plug 41 inflates the container body 40 to make it difficult to attach a label. Even before the beverage or the like is filled, the container body is not flat in the vicinity of the spout, so that it is similarly difficult to attach. As a result, at present, the operator attaches the label to a portion that is more easily attached than a portion that is easily visible.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems. A label is affixed to a predetermined position of a sheet before bag making, and the label-attached sheet is made into a bag. It is an object of the present invention to easily attach a label to a desired position of a container body, to easily automate a series of bag making steps including a label attaching step, and to improve productivity.

DISCLOSURE OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the feature of the present invention is to continuously form a bag-shaped container body from a supplied long sheet. ,
A method for producing a bag-like container with a plug for attaching a plug to an upper edge portion of the container body, wherein a label is attached to a predetermined position of a long sheet before bagging the container body. .

Since the label is affixed to the long sheet before the container body is made into a bag, the label is continuously placed at a predetermined position of the flat sheet which is stably fed out and supplied. Can be stably and reliably attached. Then, by forming a bag from the sheet body to which the label is attached, a container body having the label attached to a predetermined portion can be manufactured. In addition, the operation of attaching the label to the long sheet can be easily performed by the labeler.

Further, it is preferable that the label attached to the container body is simultaneously cut when the continuous container bodies are cut individually.

BEST MODE FOR CARRYING OUT THE INVENTION

An embodiment of the present invention will be described below with reference to the drawings. FIGS. 1 to 3 show an embodiment of the present invention, and FIG. 3 shows a container as a standing pouch which can stand on its own. In FIG. 1, reference numeral 1 denotes a container body formed by forming a long sheet 2 having flexibility into a bag shape. In the container body 1, a sports drink, a fruit juice drink, a lotion,
Various liquids such as liquid detergent are filled.

The container body 1 has rectangular side walls 5 and 5,
A bottom wall 6 is provided to extend freely from the lower edges of the side walls 5 and 5 and bent inward into a gusset.
Note that the portions with dots indicate the heat seal portions of the sheet 2. In the present embodiment, the side edges 9 and the upper edge 1a of the container body 1 are heat-sealed.

The material of the sheet 2 constituting the container body 1 is not particularly limited as long as it has flexibility. For example, a polyester film such as polyethylene terephthalate or a polyamide film or the like and an aluminum foil Laminated film in which a heat-sealing resin layer such as polyethylene or polypropylene is formed on the inner surface of a film in which a gas barrier film such as an ethylene-vinyl alcohol copolymer film or a film on which an inorganic substance is deposited is laminated, or other synthetic resin Any material such as a film can be used. In short, any material can be used as long as the inner surface can be heat-sealed and a beverage or other object to be stored can be stored inside.

Reference numeral 10 denotes a cylindrical stopper for taking out the liquid from the container body 1, and the stopper 10 is simultaneously held when the upper edges 1a of the container body 1 are sealed by heat sealing. The mounting portion 12 and the conduit portion 13 extending from the mounting portion 12 into the container main body 1 are integrally molded with the inner surface of the sheet body 2 using a synthetic resin having good heat sealing properties. A cap 16 is detachably screwed to the mouth 14 of the part 12.

At an arbitrary position of the container body 1, a label 15 for a campaign or the like on which a predetermined display is printed is attached. The label 15 has, for example, a rectangular shape as shown in FIG. 3, and is affixed to the upper corner of one or both side walls 5.

Next, a method for producing the bag-like container with a plug will be described. In FIG. 1, first, for example, a roll 2
The raw film 2 as a long sheet unwound from 0 is folded into two folds via a raw material feeding step 21. In the web feed step 21, the web film 2 is formed into a flat portion 2a that is substantially horizontal,
The label 15 is continuously attached to a predetermined position of the flat portion 2a by a labeler not shown (for example, a tack label in the case of a tack label). The flat portion 2a may be horizontal or inclined. The position where the label 15 is affixed, for example, when the bag is made in the container body 1 shown in FIG. The original film 2 is folded in two such that the outer side is outside.

Next, in the bottom folding step 22, the original film 2 is folded with the folded bottom component. Thereafter, the folded portion of the raw film 2 is heat-sealed by the lower sealing device 24 disposed in the bottom sealing step 23. Further, in the side sealing step 25, the film is nipped at predetermined intervals by a side seal bar (side sealing device) 26 and heat-sealed.

Then, the continuous side seal portion 9 is punched out by a punching device 28 in a punching step 27 to be divided and formed into a self-supporting bag (see FIG. 2A). In the punching step 27, the raw film 2
In addition, an extra portion 15a of the label 15 can be punched. In such a case, the label 15 can be stably adhered to the edge of the corner of the container body that is unstable and difficult to stick. Since the label can be attached in this manner, for example, in the case of a decorative label such as a hologram label, the decorative property can be improved while having a sense of unity with the container body.

Further, the upper edge 1a of the container body 1 is opened, and a plug 10 is inserted and supplied between the opened upper edges 1a. The upper edge 1a and the mounting portion 12 of the plug 10 are heat-sealed by a welding device (not shown), and after the liquid is filled into the container body 1 through the plug 10, the plug 10 is closed.
After being sealed with, it is discharged as a self-supporting package with a stopper.

As shown in FIG. 2B, when the label 15 is provided on both upper corners of the container body 1, the label 1
5 may be affixed to a portion of the long sheet extending over both adjacent container bodies 1.

In the manufacturing method shown in FIG. 1, the case where the container body 1 is formed from one sheet body 2 is exemplified. However, the method for manufacturing the container body 1 from a plurality of long sheet bodies is described. An example is shown in FIG. In the manufacturing method of FIG. 4, the raw material supply unit 30 supplies the bottom raw material sheet 31 in a folded state, and unwinds a pair of side wall raw sheets 32 from the raw material roll. The sheet 31 is supplied so as to be sandwiched.

The label 15 is attached to one or both of the side wall raw sheets 32 in the raw sheet feeding step 21 of the bottom raw sheet 31 and the side wall raw sheet 32. When the labels 15 are applied to both the side walls 32, the labels can be applied to both side walls 5, 5 of the container body 1.

Further, similarly to the case shown in FIG. 1, after the container body 1 to which the label 15 has been affixed through a bottom sealing step 23, a side sealing step 25, and a punching step 27, a plug 10 is attached to the container body 1. Attach.

The present invention is not limited to the manufacturing method shown in FIGS. 1 and 4. For example, in the side sealing step 25, the long sheet can be heat-sealed and cut. In the later punching process 2
7 can be omitted. In the punching step 27, the sheet body may be simply cut.

The position at which the label 15 is attached to the container body 1 is not particularly limited. As shown in FIG. 5, the label 15 is attached to a portion of the side wall 5 which is swollen by the plug 10. Is also possible. Also in this case, the label can be attached without being affected by the plug since the container is attached to a long sheet before the container body 1 is manufactured. Moreover,
The label 15 may have any shape other than a rectangular shape, and the number of labels 15 is not particularly limited.

Further, the shape of the container body may not necessarily be self-supporting, and the lower portion may not be formed in a gusset shape.

[0028]

As described above, according to the present invention, a bag-shaped container body is continuously formed from a supplied long sheet, and a plug is attached to the upper edge of the container body. In the method for manufacturing a container, a label is attached to a predetermined position of a long sheet before bagging the container body, so that the container body has flexibility and a spout is attached. The label can be easily and easily attached to a desired position on the container body.

In addition, a label can be attached to a long sheet to be fed by a labeler or the like, and a series of automation of a bag making process can be easily achieved, thereby improving productivity.
