Description

The present invention relates to the production how labeled pouch label affixed to the side gusset portions which are folded inwardly.

Conventionally, as a container for filling a filling such as beverages, jelly-like foods, retort foods, etc., it is made of a flexible film, and includes a front surface portion and a back surface portion, and a side gusset portion folded inward between the front and back surface portions. A pouch with side gussets is known.
Such a pouch is used in a state in which a filling is enclosed inside, or in the form of a pouch container with a spout in which a spout for filling filling is attached to the top of the pouch and the filling is enclosed inside.

When a pouch having such a side gusset portion is mechanically made, the procedure is as follows.
As shown in FIG. 10, a long surface film original fabric 120 and a rear film original fabric 130 that form the front and back portions of the pouch (in each of the front and rear film original fabrics 120, 130, individual pouches that are bag-made). Corresponding to the above, the long side original film forming the side gusset portion 150 is sandwiched between both sides of the same design display (printed at a predetermined interval in the longitudinal direction). While feeding this, it is heated from above and below the front and back film original fabrics 120 and 130 by the vertical seal device 210, and the inner surfaces of the side end portions of the front and back film original fabrics 120 and 130 and the side end portions of the respective side film original fabrics 150 The inner surface is heat-sealed with a predetermined width. Then, the lower end part is heat-sealed with the horizontal sealing apparatus 220, and this is cut | disconnected in the horizontal direction with the cutter 230, and the pouch 100 by which one design display was represented by the front and back part is obtained. By performing this continuously, a large number of pouches 100 can be manufactured. Thereafter, the opening putting packing from the top opening by heat-sealing can be produced pouches were sealed packing. Moreover, the pouch container with a filled spout can be manufactured by heat-sealing this with the spout sandwiched in the opening, filling the spout, and attaching a spout cap.

By the way, conventionally, various labels such as campaign labels used as application tickets for lotteries and giveaways are affixed to various products such as beverage containers and food containers.
When affixing such a label to the side gusset part of the pouch, the label cannot be attached unless the folded side gusset part is unfolded before the filling is sealed, and the label affixing operation is difficult. . On the other hand, after filling, the side gusset part expands as the entire pouch swells, but even if the label is pressed against the side gusset part, the side gusset part curves inward, so the label is attached with sufficient pressing force. Can not.

From this point, when manufacturing the pouch, a label is affixed to the outer surface of the side film original fabric 150 at a predetermined interval so that one label corresponds to each pouch to be bagged. It is conceivable that the side film original fabric 150 is folded between the front and back film original fabrics 120 and 130 to form a bag.
However, in the above manufacturing method, the front film original fabric 120, the back film original fabric 130, and the side film original fabric 150 are composed of separate and independent long films. The front and back film original fabrics 120 and 130 and the side film original fabric 150 are displaced in the longitudinal direction.
Thus, since the front and back film original fabrics 120 and 130 and the side film original fabric 150 are displaced in the longitudinal direction during bag making, the design indication printed on the front film original fabric 120 (or the back film original fabric 130) is displayed. As a reference, there is a problem in that the label of the side film original fabric 150 is not in a predetermined position, and a large number of pouches whose label application positions are shifted with respect to the design display on the surface portion are manufactured.

Accordingly, the present invention is to surface portion (or the back surface) as a reference, and to provide a manufacturing how that can mass-produced labeled pouch label in a predetermined position of the side gusset portions is affixed.

The present invention is a method for manufacturing a pouch that is formed of a single film and has a front surface portion and a back surface portion, a side gusset portion that is folded between the front and back surface portions, and a spout attached to the upper end portion of the front and back surfaces. Folding step of folding the side gusset portion forming region of one long film original fabric between the front and back surface forming regions of the film original fabric, side end portions and front and back surface forming regions of the side gusset portion forming region Adhesive process for heat-sealing the side end of the bag, and after bag making, a spout is sandwiched in the opening at the upper end of the front and back surfaces, and the upper end is heat-sealed together with the spout, before the folding process or the folding process during, between the side edge that will be heat-sealed folds before SL side surface gusset portion forming region and a outer surface of the side gusset portion forming region is formed in the widthwise center portion of the side gusset portion forming region, label To provide a method of manufacturing a label with a pouch to be attached.

According to the method for manufacturing a labeled pouch, before or during folding of the side gusset portion forming region of the original film, the outer side surface of the side gusset portion forming region is formed at the center in the width direction of the side gusset portion forming region. since locating the label between the folds and the front SL side surface gusset portion side end portion is heat sealed Ru forming region to be, there is no need to deploy the side gussets for labeling.
And since the front and back surface forming area and the both side gusset forming area are made of a single film, when the side gusset forming area is folded between the front and back surface forming areas, the front and back surface forming area and the side gusset forming The region is not displaced in the longitudinal direction.
Therefore, a large number of the same pouches with labels attached to predetermined positions of the side face gusset portion can be manufactured with reference to the front surface portion (or back surface portion).

The method for manufacturing a labeled pouch according to the present invention can manufacture a large number of the same labeled pouches with labels attached to predetermined positions of the side face gusset portion with reference to the front and back surfaces.
In addition, since the above-described manufacturing method only attaches a label to a predetermined position on the outer surface of the side surface gusset portion forming region before or during folding the side surface gusset portion forming region into the front and back surface portion forming region, for example, to an existing pouch bag making machine. By simply adding a label attaching device, a large number of the same labeled pouches with labels attached to predetermined positions of the side gusset portion can be manufactured.

Hereinafter, the present invention will be specifically described with reference to the drawings.
1 to 3, 1 is folded between the front surface portion 2 and the back surface portion 3 and the front and back surface portions 2 and 3 (hereinafter, the front surface portion and the back surface portion may be collectively referred to as the front and back surface portions). In addition, a pouch with a label having both side gusset portions 5 and 5 is shown, and a label 7 is attached to the outer surface of the side gusset portion 5.

Corresponding to the position indicated by this sticking instruction display, the label 7 is stuck on the gusset portion 15, whereby the sticking position of the label 7 can be accurately recognized by the user.
A design display may also be printed on the side gusset portion 5.

The pouch can be mechanically manufactured in the following bag making process, for example.
<Pre-process>
First, a single long film original 10 having a width capable of forming one pouch 1 (front and back surface portions 2, 3 and both side gusset portions 5, 5) is prepared.
This film original fabric 10 is used when forming one row of pouches 1 in the width direction, but when forming two rows of pouches 1 in the width direction, the film original fabric 10 is more than double the width of the film original fabric 10. In the case of preparing an X film pouch and forming X rows of pouches in the width direction, a film original that is X times wider than the film original 10 may be prepared. Hereinafter, a case where one row of pouches 1 is formed in the width direction will be described as an example.
On the outer surface of at least the surface portion forming region 12 of the long film fabric 10, the same design indication (only the arrow marks are shown in the figure) corresponding to the individual pouches 1 to be produced in the longitudinal direction. Are printed at predetermined intervals.
A label affixing step of attaching the label 7 to the outer surface of the side gusset portion forming region 15 of the one sheet of original film 10, and the side gusset portion forming region 15 of the film original fabric 10 10 through the folding step of folding between the front and back surface forming regions 12 and 13 and the bonding step of bonding the side end portions of the side surface gusset forming region 15 and the side end portions of the front and back surface forming regions 12 and 13. 1 is manufactured. Hereinafter, each process will be described in order.

<Creasing process>
As shown in FIG. 4, the above-mentioned long film original fabric 10 wound up in a roll shape is pulled out, and a roller of the crease forming device is provided on the inner surface side (or the outer surface side) of the film original fabric 10. As a result, a plurality of creases 16 and 17 (represented by alternate long and short dash lines) are formed linearly in the longitudinal direction in the width direction. Via the crease 16, the original film 10 is composed of a surface portion forming region 12 that forms the surface portion 2, a side surface gusset portion forming region 15 that forms one side surface gusset portion 5, and a back surface portion forming region that forms the back surface portion 3. 13 and is divided into side gusset portion forming regions 15 that form the other side gusset portion 5. A crease 17 is formed at the center of the side gusset portion forming region 15.
Depending on the bag making apparatus, the crease forming step may be omitted.

<Labeling process>
The original film 10 is pulled out, and the label 7 is stuck to a predetermined position on the outer surface of the one side gusset portion forming region 15 by a label sticking device. The label 7 is affixed at a predetermined position on the basis of the design display printed on the front surface forming region 12 (or the back surface forming region 13) or the design display printed on the side surface gusset forming region 15. For example, when a sticking instruction display such as the arrow mark is printed on the surface portion forming region 12, the label 7 is stuck at a position corresponding to the sticking instruction display. A plurality of such labels 7 are affixed in the longitudinal direction of the side gusset portion forming region 15 with a predetermined interval (with an interval such that the label 7 is affixed to each pouch 1 to be produced). . Since the label 7 is affixed to a predetermined position of the side gusset portion forming area 15, even when an important design display such as component display is printed on the side gusset portion forming area 15, It is possible to prevent the label 7 from being stuck on the top.
The label 7 includes a fold 16 formed at the boundary line between the side gusset portion forming region 15 and the front and back surface forming regions 12 and 13, and a fold 17 formed at the center in the width direction of the side gusset portion forming region 15. It is affixed between.
In addition, a label sticking process can also be performed before the said crease formation process.

<Folding process>
Next, as shown in FIG. 5, the original film 10 is folded along the folds 16 and 17 by a folding device. That is, the fold 16 between the side gusset portion forming region 15 and the front and back surface forming regions 12 and 13 of the original film 10 is folded outward and the side fold 17 is formed at the center of the side gusset portion forming region 15. The gusset portion formation region 15 is folded inward, and the side gusset portion formation region 15 is folded between the front and back surface formation regions 12.13.
As shown in FIG. 6, the original film 10 that has undergone the folding process is in a state in which the side gusset portion forming regions 15, 15 are folded in a substantially V shape between the front and back surface forming regions 12, 13. ing.
In addition, it is also possible to perform the said label sticking process in a folding process. For example, the label 7 may be attached to a predetermined position of the side gusset portion forming area 15 while the side gusset portion forming area 15 is folded inward. However, it is preferable to perform the label attaching step before the folding step because the label 7 can be reliably attached to the side gusset forming region 15.

<Adhesion process>
Next, the longitudinal sealing device heat seals both side ends of the side surface gusset portion forming regions 15 and 15 and both side end portions of the front and back surface forming regions 12 and 13 in the longitudinal direction by a predetermined width, The lower end portions of the front and back surface forming regions 12 and 13 are heat-sealed in the width direction. Thereby, a pouch continuum in which a plurality of pouches are connected in the longitudinal direction is obtained.

<Cutting process>
Then, in order to obtain individual pouches from the pouch continuum, the upper surface portion is cut in the width direction while cutting off excess portions of the heat seal portions formed at the lower end portions of the front and back surface forming regions 12 and 13. Open pouches are obtained. Open pouches are mass-produced by cutting the pouch continuum that is sequentially sent.

<Spout mounting process>
Finally, the pouch 1 with the spout is manufactured by sandwiching a spout in the opening of the pouch with the upper end opened and heat-sealing the upper end together with the spout.

Since the label 7 is pasted at a predetermined position of the side gusset portion forming region 15 before folding the side gusset portion forming region 15 of the original film 10, the side pouched portion is used for label sticking. There is no need to expand 5.
Furthermore, since the front and back surface forming regions 12 and 13 and the both side gusset forming regions 15 and 15 are made of a single film original 10, the side gusset forming region 15 is folded between the front and back surface forming regions 12 and 13. At this time, the front and back surface forming regions 12 and 13 and the side surface gusset forming region 15 are not displaced in the longitudinal direction.
Therefore, according to the said manufacturing method, many same pouches 1 with a label by which the label 7 was affixed on the predetermined position of the side surface gusset part 5 can be manufactured on the basis of the design display of the surface part 2 (or back surface part 3). .
Moreover, since the manufacturing method should just affix the label 7 in the predetermined position of the outer surface of the side gusset part formation area 15 before folding the side gusset part formation area 15, the existing pouch bag making machine equipped with a label application apparatus A large number of the same labeled pouches 1 can be produced simply by adding a labeling device to a machine or an existing pouch bag making machine.

  The present invention is not limited to the above-described embodiments, and can be modified, substituted, replaced, added, and the like. Hereinafter, parts different from those of the above embodiments will be mainly described, and the same configuration may be referred to using terms and figure numbers, and the description thereof may be omitted.

The labeled pouch 1 of the present invention can be used in the form of a pouch container with a spout as described above, or in the form of a bag in which a filling is enclosed without attaching the spout 8.
In addition, the filling material enclosed in the pouch 1 is not particularly limited, in addition to jelly-like foods, frozen desserts such as ice cream, cooked foods such as beverages and curries, uncooked foods such as dried foods, and foods such as powders. And non-food products such as chemicals, medical-related products, chemical products such as detergents, toys, and industrial product parts.

Further, in the above, the pouch 1 in which the side gusset portions 5 are formed on both sides is illustrated, but as shown in FIG. 7, the present invention is applied to the pouch 1 in which the side gusset portions 5 are formed only on one side. You can also
Moreover, in the above, although the pouch 1 which consists of the front and back surface parts 2 and 3 and the side gusset part 5 is illustrated, for example, a separate film is interposed under the front and back surface parts 2 and 3, and these are heat-sealed. Thus, the present invention can also be applied to pouches having front and back surface portions 2, 3, side gusset portions 5, and a bottom surface portion.
The front and back surface portions 2 and 3 are not limited to those formed in a front hexagonal shape, but may be formed in a front rectangular shape, or may be formed in a front rectangular shape, a front octagonal shape, or the like.

Moreover, in the manufacturing method of the said labeled pouch 1, although an adhesion process is performed after a folding process, an adhesion process can also be performed in two steps before and after a folding process.
Specifically, in the same manner as described above, after the pre-process, the crease forming process, and the label attaching process, the following process is performed.
<First bonding step>
As shown in FIG. 8, one sheet of original film 10 with folds 16 and 17 formed (in the case where the crease forming step is omitted as described above, the original film 10 without the folds 16 and 17). The inner surfaces of both side end portions are overlapped, and heat sealing is performed in the longitudinal direction by a vertical sealing device. As a result of this adhesion, one sheet of original film 10 is formed into a long cylindrical body as shown in FIG.

<Folding process>
Next, the said cylindrical film original fabric 10 is bend | folded along the crease | folds 16 and 17 with a folding apparatus. The folding method is the same as described above. As a result, as shown in FIG. 9B, a cylindrical body is obtained in which the side gusset portion forming regions 15, 15 are folded in a substantially V shape between the front and back surface forming regions 12, 13.

<Second bonding step>
Next, in the same manner as in the above-described embodiment, the vertical sealing device heat-seal both side ends of the side surface gusset portion forming region 15 and both side ends of the front and back surface forming regions 12 and 13 in the longitudinal direction, and The lower end portions of the front and back surface forming regions 12 and 13 are heat-sealed in the width direction by the horizontal sealing device. Thereby, a pouch continuum in which a plurality of pouches are connected in the longitudinal direction is obtained.
Thereafter, through the steps after the cutting step, a number of the same labeled pouches 1 with the label 7 attached to a predetermined position of the side face gusset portion 5 are manufactured.

  Furthermore, in the manufacturing method of the pouch according to the modified example in which the bonding process is performed before and after the folding process, the label sticking process is performed before the first bonding process. A label sticking process can also be performed between 1 adhesion process and a folding process. That is, after a single film original 10 is formed into a cylindrical body in the first bonding step, the label 7 is attached to a predetermined position of the side surface gusset portion forming region 15 of the cylindrical body, and then the side surface gusset The part forming region 15 can be changed to a procedure of folding between the front and back surface forming regions 12 and 13.
