Description

  The present invention is used as a container for refilling detergents, bleaches, softeners, laundry glue, shampoos, rinses, etc., and when these contents are refilled into other containers, the contents are poured out. The present invention relates to a refill pouch provided with a nozzle portion for performing the refill pouch, a refill pouch inspection method, and a refill pouch manufacturing method.

In recent years, with the increasing awareness of recycling, there are many refill pouches with a nozzle part for pouring the contents as refill containers that are used by refilling the contents into other containers such as plastic bottles and glass bottles. It has come to be used.
This type of refill pouch is formed by cutting out the tip of the nozzle part and opening it, so that a spout is formed in the nozzle part. Normally, the nozzle part is easily opened. Thus, easy-opening processes, such as forming a tear line along the site | part used as a spout, are given (for example, patent document 1 etc.).

JP 2003-327255 A

  By the way, this type of refillable pouch is generally manufactured by making a bag while sequentially feeding out a long raw material made of a soft packaging material such as a resin film. In the bag making process, for example, Each process such as heat sealing, easy opening, and cutting is performed in a flow-oriented manner. At this time, there is no particular problem as long as the raw material is fed out with high accuracy, but if the raw material is meandered and fed out, there will be a shift in the processing position in each step.

  In particular, the tear line formed in the easy-opening process determines the shape of the spout from which the contents are poured out, and the position where the tear line is formed and the shape of the tear line are only the unsealing property of the nozzle part. In addition, since it is determined by comprehensively considering the content pouring property and the insertion property when inserting the nozzle into the inlet of another container, the misalignment of the tear line is a characteristic of these products. Will be significantly impaired.

  For this reason, products manufactured with the position of the cut line shifted must be removed as defective products.Even if the amount of shift is small, the product characteristics are greatly affected, and visual sorting is difficult. there were. In particular, when a cut line is formed by laser grooving on the surface of the material, the cut line is hidden by the shape and printing of the nozzle part and is difficult to see. After determining the position, it has been necessary to actually measure how much the deviation is, which is very laborious.

Also, if the misalignment of the cut line is detected at an early stage that exceeds the allowable range, the production is stopped at that point and the raw material is set again to minimize the occurrence of defective products. However, the meandering at the time of unwinding the raw material is not obvious at first glance, and the displacement of the cut line gradually increases by a small amount. In addition, as described above, a complicated operation is required to detect the misalignment of the cutoff line.
For this reason, there are many cases where the production is continued without noticing that the position where the cut line is formed is shifted.In such a case, a large number of defective products are generated and the yield is reduced. In addition, a lot of manpower is required for the sorting work, and there is a manufacturing problem that the production efficiency is remarkably lowered.

  The present invention has been proposed in order to solve the above-described problems of the prior art, and facilitates determination of whether or not the position of the cut line formed in the nozzle portion is displaced. The purpose of the present invention is to provide a refill pouch that does not require time and effort to sort out defective products, and can easily detect the occurrence of defective products, a refill pouch inspection method, and a refill pouch manufacturing method. To do.

The refill pouch according to the present invention comprises a nozzle portion for pouring out the content when the content is refilled into another container, and the tip portion of the nozzle portion is cut off on both the front and back surfaces of the nozzle portion. Te, Note with cut lines for forming an outlet is formed close to the corners of the heat-sealed portion in the tip section, and the both sides of the flat portion, a predetermined said cut line of said nozzle portion marker for determining whether they are formed in positions, is a configuration in which a relative positional relationship between the cut lines are formed to be constant.

  By adopting such a configuration, it is not necessary to look at the cut line itself and determine whether the formation position is appropriate, but the cut line is placed at a predetermined position by a marker that is formed much easier to see than the cut line. It can be determined whether or not it is formed, and thereby, defective products can be easily selected.

In particular, the distance between the top edge and the side edge of the refill pouch and the marker is determined by forming the marker on both the front and back surfaces of the flat portion near the corner of the heat seal portion at the tip portion. It becomes possible to easily measure with a simple measuring instrument such as the above, and it is possible to easily measure the positional deviation of the cut line.

And, by forming the cut line and the marker on both front and back surfaces of the nozzle part, each of the cut line formed on the front side of the nozzle part of the refill pouch and the cut line formed on the back side Not only can it be easily determined whether or not it is formed at a given position, but the direction of the misalignment of the cutting line is different on the front side and the back side, even if there is a problem that the unsealing performance will deteriorate, This can be easily discovered.

  In the refill pouch according to the present invention, in order to form the cut line and the marker so that the relative positional relationship is constant, it is preferable to form the cut line and the marker substantially simultaneously. In addition, the occurrence of a problem due to the shift of the cut line formation position is particularly noticeable when the cut line is formed in a curved shape, but according to the refill pouch according to the present invention, It is possible to easily select defective products.

Moreover, the refilling pouch according to the present invention may have a configuration in which an engaging portion that engages with the opening peripheral edge of the inlet of the other container is formed at the base portion of the nozzle portion.
Even when such a configuration is adopted, according to the present invention, the formation position of the cut line is shifted, and the engaging portion disappears or is missing when the tip portion of the nozzle portion is cut off. It is easy to find things that have such problems.

Further, the refill pouch inspection method according to the present invention is a refill pouch provided with a nozzle part for pouring out the contents when the contents are refilled into another container. An inspection method for determining whether or not cut lines formed on both front and back surfaces of the nozzle portion in order to cut and form a spout are formed at predetermined positions of the nozzle portion, the cut line being the nozzle When forming the portion , a marker is formed on both the front and back surfaces of the flat portion near the corner of the heat seal portion at the tip portion so that the relative positional relationship with the cut line is constant. , the refill from the top on the edge and side edge of the pouch measuring the distance to the marker, the method determines the cut line, or positional deviation of the degree occurs entirety in .
Thus, whether or not a cut line is formed at a predetermined position of the nozzle portion is determined based on the position where the marker is formed, and thereby it becomes possible to easily select defective products.

In the inspection method of the refill pouch according to the present invention, said marker is, so as to be formed on the heat-sealed portion of the tip portion of the nozzle portion of the refill pouch, in this case, the marker is If the refill pouch is not formed in the heat seal portion at the tip of the nozzle portion, it can be determined that the cut line is not formed at a predetermined position of the nozzle portion. Selection of non-defective products becomes easier.

Moreover, the manufacturing method of the refilling pouch according to the present invention is a process in which a refilling pouch having a nozzle portion for pouring the contents is made while the long raw material is sequentially fed. A method for manufacturing a refill pouch in which a cutting line for forming a spout in the nozzle part by cutting off a tip portion of the nozzle part is formed on both front and back surfaces of the nozzle part , wherein the cutting line is formed. A marker for determining whether or not the cut line is formed at a predetermined position of the nozzle part on both the front and back surfaces of the flat part close to the corner of the heat seal part in the tip part , the cut line As a method of forming such that the relative positional relationship is constant.
This makes it easy to know the occurrence of defective products due to misalignment of the cut line, and it is effective to continue production without noticing the occurrence of defective products, resulting in a large number of defective products. Can be avoided.

  In the refill pouch manufacturing method according to the present invention, it is preferable that the cut line and the marker are formed by a laser marker in the same step, and thereby the relative positional relationship between the cut line and the marker is easy. Can be constant.

  As described above, according to the present invention, the marker for determining whether the cut line is formed at a predetermined position of the nozzle portion is formed so that the relative positional relationship with the cut line is constant. Therefore, it is not necessary to look at the cut line itself and determine whether or not the formation position is appropriate, but depending on whether or not the marker formed is much easier to see than the cut line is formed within a predetermined range. It is possible to determine the misalignment and thereby easily select defective products.

  Furthermore, since it is possible to easily know the occurrence of a defective product in which the cut line is not formed at a predetermined position, it is possible to continue manufacturing without noticing the occurrence of the defective product, resulting in a large number of defective products. Such a situation can be effectively avoided, and the production of defective products can be minimized by stopping production at an early stage when defective products are generated.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[Refill pouch]
FIG. 1 is a plan view showing an outline of a refill pouch according to the present embodiment, and a refill pouch 10 includes a body 11 and a bottom 12 formed of a soft packaging material such as a resin film. . A side seal 13 is applied to the peripheral edge of the body 11 with the bottom 12 folded, and a bottom seal 14 is applied between the body 11 and the bottom 12.

  Such a refilling pouch 10 is formed by folding the bottom member 1c between the front surface material 1a and the back surface material 1b (see FIG. 6). Although it manufactures by performing each process, such as a sealing process, an easy opening process, and a cutting process, in flow work (refer FIG. 7), the detail of a manufacturing method is mentioned later.

In the example shown in FIG. 1, the top portion of the refill pouch 10 is an unsealed portion, but the top portion of the refill pouch 10 is normally transported to the content filling step in an unsealed state, and the content is filled. After the top seal is applied.
The refill pouch 10 filled with the contents expands at the folding line 12a in the folded bottom 12 so that the refill pouch 10 becomes a cone or a pyramid and can be made to stand on its own.

Further, in the illustrated example, a nozzle portion 16 that protrudes obliquely upward is formed at the corner of the upper left body portion 11 in the drawing. A cut line 18 that intersects the nozzle portion 16 is formed in the nozzle portion 16, and a notch 15 is formed at the cut start position.
The cut line 18 is formed to cut and open the tip portion 19 of the nozzle portion 16, and the nozzle portion 16 after the tip portion 19 is cut along the cut line 18 contains other contents. A spout 16a serving as a spout when refilling the container is formed (see FIG. 5).

Further, in the illustrated example, the side seal 13 is partially inclined from the midway portion of the left side seal 13 in the drawing to the base of the nozzle portion 16 to form a relief portion 17.
The escape portion 17 is formed in order to avoid interference between the refill pouch 10 and another container in which the contents are refilled during the refilling operation, and the escape portion 17 side of the base portion of the nozzle portion 16 Is formed with an engaging portion 17a for engaging with the peripheral edge of the inlet of another container to stabilize the posture of the refill pouch 10.

In the refilling pouch 10 according to the present embodiment having such a shape, the cutoff line 18 is formed by performing groove processing on the surface of the soft packaging material using, for example, an optical reflective laser marker. be able to.
The optical reflection type laser marker can move the focal point of the laser by manipulating the optical axis (angle) of the mirror, and can easily process complex patterns and patterns by manipulating the optical axis (angle) of the mirror. Can do. As the laser, it is preferable to use a carbon dioxide laser capable of selective processing according to the type of the resin film.

At this time, the cut line 18 is preferably not formed by a single continuous groove or a single broken line-shaped groove, but, for example, as a set of grooves in which a plurality of continuous grooves are arranged in parallel. . Thereby, the unsealing property of the nozzle part 16 and the stability of the unsealing direction at the time of unsealing are improved, and it is possible to easily form the spout 16a having a predetermined shape by cutting the tip part 19 of the nozzle part 16 with a finger. It becomes.
In addition, the easy opening process which this applicant proposed in Unexamined-Japanese-Patent No. 2003-94532 is applicable to such a tear line 18. FIG.

In the example shown in the drawing, the cut line 18 is formed by five curved grooves arranged at almost equal intervals. Each groove constituting the cut line 18 is formed to be curved convexly toward the nozzle base portion 16b.
If the cut line 18 is formed in such a manner, the side edge of the nozzle portion 16 after the tip portion 19 of the nozzle portion 16 is cut and the spout 16a is formed within a range that does not impair the unsealing property of the nozzle portion 16. Can be long. Thereby, the length of the whole nozzle part 16 is securable. As a result, the nozzle portion 16 can be easily inserted into the inlet of another container in which the contents are refilled, so that the contents can be prevented from spilling during the refilling operation. .
Furthermore, if the cut line 18 is formed as described above, the spout 16a is formed in a curved shape, the cross-sectional area of the nozzle portion 16 can be substantially expanded, and the amount of content to be poured is increased. The refilling operation can be completed quickly.

Thus, since the cut line 18 determines the shape of the spout 16a, if the cut line 18 is formed out of the proper position, the unsealing property of the nozzle portion 16 and the contents are poured out. This greatly affects the product characteristics of the refill pouch 10, such as the insertion performance when the nozzle portion 16 is inserted into the inlet of another container.
Here, an example in which the formation position of the cut line 18 is deviated from that in which the cut line 18 is formed at an appropriate position will be described below.

  FIG. 2 shows a state in which a cut line 18 is formed at an appropriate position of the raw material that is sequentially fed when the refill pouch 10 is manufactured. The cut line 18 is formed in the raw material with a certain margin, but the portion protruding from the nozzle portion 16 is cut along the contour line of the refill pouch 10, thereby cutting as shown in FIG. 4. A line 18 is formed in the nozzle portion 16. And if the front-end | tip part 19 of the nozzle part 16 is cut along the cut line 18, the spout 16a as shown in FIG. 5 will be formed.

On the other hand, FIG. 3 conceptually shows a state in which the cut line 18 is formed so as to be shifted from the state in which the cut line 18 is formed at an appropriate position (FIG. 2). An outline of a state in which a cut line 18 is formed at an appropriate position is shown.
The contour line indicated by the alternate long and short dash line in FIG. 3 shows an example in which when the cut line 18 is formed, the raw material is shifted downward in the figure, and the cut line 18 is relatively shifted upward in the figure. Yes. 3 is an example in which when the cut line 18 is formed, the raw material is shifted upward in the figure, and the cut line 18 is relatively shifted downward in the figure. Is shown.
In addition, in the example shown in the figure, for the sake of easy understanding, it is assumed that meandering occurs in the feed of the raw material, and the cut line 18 is formed so as to be shifted only in the direction orthogonal to the feed direction. However, in actuality, the shift in the feed direction must be taken into account, and the position shift of the cutoff line 18 is actually more complicated.

In this way, when the cut line 18 is formed out of the proper position, the unsealing property of the nozzle portion 16 is impaired, or the shape of the nozzle portion 16 after unsealing and the shape of the spout 16a are intended. The product characteristics such as the content pouring property and the insertion property when the nozzle portion 16 is inserted into the inlet of another container may be impaired. Further, the engaging portion 17a formed at the base portion of the nozzle portion 16 may be cut out together with the tip portion 19 and disappear or be lost.
Such a problem becomes particularly noticeable when the cut line 18 is formed in a curved shape as in the illustrated example.

Since the cut line 18 is formed so as to deviate from its proper position beyond its allowable range, it has to be removed as a defective product because of the above-described defects.
However, as described above, the effect on the product characteristics is large even with a small deviation, and in particular, when the cut line 18 is formed by grooving the surface of the material with a laser, the shape of the nozzle portion 16 and the clogging are reduced. The cut line 18 is difficult to see behind the printing applied to the replacement pouch 10, and it is difficult to select defective products by determining whether the position of the cut line 18 itself is appropriate.

For this reason, in this embodiment, when forming the cut line 18, the marker 20 for determining whether or not the cut line 18 is formed at a predetermined position of the nozzle portion 16 is the same as the cut line 18 shown in FIG. By forming the nozzle portion 16 together with the cutoff line 18 while maintaining the positional relationship, the relative positional relationship with the cutoff line 18 is formed to be constant. As a result, the defective product formed by shifting the cut line 18 from the proper position can be easily selected.
That is, according to the present embodiment, when inspecting whether the manufactured refill pouch 10 is a non-defective product or a defective product, the cutting line 18 itself is viewed to determine whether the cutting line 18 is formed properly. Instead of determining, it is possible to determine whether or not the cut line 18 is formed at a predetermined position of the nozzle portion 16 by using the marker 20 formed so as to be much easier to see than the cut line 18. Good products can be easily selected.

  Specifically, as in the example shown by the two-dot chain line in FIG. 3, if the cut line 18 is formed to be shifted upward, the marker 20 is also formed to be shifted upward. In FIG. If the cut line 18 is formed to be shifted downward as in the example, the marker 20 is also formed to be shifted downward, so that the marker 20 is positioned within a predetermined range of the nozzle portion 16. Thus, it is determined whether or not the cut line 18 is formed at a predetermined position of the nozzle portion 16, and thereby, it is only necessary to inspect whether the manufactured refill pouch 10 is a good product or a defective product.

  At this time, if the marker 20 is formed in the heat seal part at the tip part 19 of the nozzle part 16 which is close to the corner and flat as in the example shown in the figure, the top upper edge and the side side edge of the refill pouch 10 are formed. The distance from the marker 20 to the marker 20 can be easily measured with a simple measuring instrument such as a ruler, thereby making it possible to easily measure how much misalignment has occurred.

  In addition, when actually trying to measure the positional deviation of the cut line 18, it is necessary to perform measurement by setting different standards for each product in accordance with the shape of the nozzle portion 16, but in the present embodiment, this is not necessary. If the position where the marker 20 is formed is determined, the same measurement can be performed for all products. In addition, the nozzle portion 16 and its vicinity are generally subjected to a three-dimensional process in order to improve the pouring property of the contents. In order to actually measure the positional deviation of the cut line 18, such a three-dimensional process is performed. The measurement must be performed while avoiding the processing, and the measurement involves complicated work, but this is not necessary in the present embodiment.

Position for forming the marker 20 is the location as described above in which the formation position is whether within a predetermined range can be easily determined, by forming the site where heat seals are subjected Refill It is possible to prevent the sealing performance of the pouch 10 from being lost as much as possible.
Further, as long as the marker 20 is formed so that the relative positional relationship with the cut line 18 is constant, its forming means is not particularly limited, but using an optical reflective laser marker as described above, It is preferable to form the cut line 18 almost simultaneously with the cut line 18 in the same process as the cut line 18 because the relative positional relationship between the cut line 18 and the marker 20 can be easily made constant.

  Further, in the illustrated example, the marker 20 is formed by marking “+”, but the shape of the marker 20 itself is not particularly limited, and for example, “◯”, “△”, “◇”, “□”. Various markings such as “☆” may be given, and the marker 20 may be formed by punching. Also, the amount of misalignment can be measured by printing a lattice pattern or the like in a range that does not affect other printed patterns applied to the refill pouch 10 at the portion where the marker 20 is formed. You can also.

The size for forming the marker 20 is also arbitrary. For example, when the marker 20 is formed on the heat seal portion at the tip portion 19 of the nozzle portion 16, the shape and size of the marker 20 and the shape and size of the heat seal portion are determined. If the marker 20 protrudes from the heat-sealed portion by appropriately setting, it can be determined that the positional deviation of the cut line 18 exceeds the allowable range.
In particular, if the marker 20 is not formed at the heat seal portion of the tip portion 19 of the nozzle portion 16 of the refill pouch 20, it is set so that it can be determined that the cut line 18 is not formed at a predetermined position of the nozzle portion 16. For example, it is obvious whether the product is a non-defective product or a defective product, and the inspection of the manufactured refill pouch 10 becomes much easier.

Further, cut lines 18 are formed on both sides of the front and rear side of the nozzle portion 16 of the refill pouch 10, the relative positional relationship between the cut lines 18 formed on each side is constant Thus, if the markers 20 are also formed on both the front surface side and the back surface side, the cut line 18 formed on the front surface side and the cut line 18 formed on the back surface side are at predetermined positions. It can be easily determined whether or not it is formed.
In particular, even if the positional deviation of the cut line 18 is within an allowable range between the front side and the rear side of the nozzle portion 16 of the refill pouch 10, the direction of the positional deviation of the cutoff line 18 is the front side and the rear side. If the cut line 18 formed on the front surface side and the cut line 18 formed on the back surface side intersect with each other, the unsealing property is deteriorated. The marker 20 is formed on the front and back surfaces of the nozzle portion 16 of the refill pouch 10 so that such a problem can be easily found .

  Moreover, in this embodiment, there is no restriction | limiting in particular as a material of the soft packaging material used for the refilling pouch 10. FIG. Examples of the resin material suitable for constituting the soft packaging material include crystalline polypropylene, crystalline propylene-ethylene copolymer, crystalline polybutene-1, crystalline poly-4-methylpentene-1, low-, and medium- Or polyolefins such as high-density polyethylene, ethylene-vinyl acetate copolymer (EVA), ethylene-ethyl acrylate copolymer (EEA), and ion-crosslinked olefin copolymer (ionomer); polystyrene, styrene-butadiene copolymer Aromatic vinyl copolymers such as polymers; halogenated vinyl polymers such as polyvinyl chloride and vinylidene chloride resins; nitrile polymers such as acrylonitrile-styrene copolymers and acrylonitrile-styrene-butadiene copolymers; nylon 6, nylon 66, polyamides such as para or metaxylylene adipamide It can be exemplified thermoplastic resins such as polyacetal such as polyoxymethylene or the like, such as, polyethylene terephthalate, polyesters polytetramethylene terephthalate; various polycarbonates. In addition to these thermoplastic resins, paper may be used. Soft wrapping materials made of these materials are used after being unstretched, uniaxially stretched, or biaxially stretched.

  Furthermore, the soft wrapping material used for the refill pouch 10 can be constituted by a single layer of these soft wrapping materials or by laminating two or more kinds, or a kind of these soft wrapping materials, or Further, two or more kinds and a metal foil such as aluminum, a vapor-deposited film of metal or metal oxide, paper, cellophane, or the like can be bonded together. As a preferred soft packaging material, for example, a stretched nylon film as an outer layer, a low-density polyethylene, a two-layer structure having a polyolefin film such as polypropylene as an inner layer, a stretched polyester film as an outer layer, and a two-layer structure having a polyolefin film as an inner layer, In addition, among these, a film having a three-layer structure in which a metal foil such as aluminum is laminated between outer layer films, etc. are included. In the production of these laminated films, an adhesive and an anchor agent are interposed between the respective layers as necessary. It can also be made.

  And the layer structure of the soft wrapping material is selected according to the properties of the contents to be filled in the refill pouch 10, for example, when a low cost is required like a refill pouch for a refill detergent, When a laminated film having a two-layer structure is used and storage stability is required like a seasoning refill pouch, a laminated film having a three-layer structure or more including an aluminum foil may be used.

[Manufacturing method of refill pouch]
Next, an embodiment of a method for producing a refillable pouch according to the present invention will be described. FIG. 7 is a process diagram schematically showing a manufacturing process of the refill pouch 10 in the present embodiment. The refill pouch 10 sequentially forms the long raw material 1 made of the soft packaging material as described above. Manufactured by making bags while feeding.
Specifically, as shown in FIG. 6, the bottom member 1c that forms the bottom portion 12 is folded between the surface material 1a that forms the front surface side of the refill pouch 10 and the back material 1b that forms the back surface side. It is manufactured by carrying out each process such as heat sealing processing, easy opening processing, cutting processing and the like as described below in a flow manner while sequentially feeding the raw material 1 that is sandwiched between and stacked.

In performing the heat sealing process, first, the bottom seal 14 is applied by the bottom seal device 101. Thereby, the bottom member 1c is heat-sealed to each of the front surface material 1a and the back surface material 1b to be integrated, and the bottom portion 12 folded at the folding line 12a is formed.
Next, the side seal 13 is applied by the side seal device 102. At this time, a part before one step corresponding to the side periphery of the right side seal 13 in FIG. 1 and a step after one step corresponding to the side periphery of the left side seal 13 in FIG. The part is heat sealed at the same time. Thereby, the surface material 1a and the back surface material 1b are integrated in the bag shape by the side seal 13, and the heat sealing process is completed.

Next, an easy-opening process is performed. At this time, the cut line 18 is formed in a portion corresponding to the nozzle portion 16 and the cut line 18 is set so that the relative positional relationship with the cut line 18 is constant. And the marker 20 are formed almost simultaneously. At this time, the cutoff line 18 and the marker 20 are formed in the nozzle portion 16 in a state where the positional relationship shown in FIG. 2 is maintained.
In the illustrated example, the first laser processing device 103 forms the cut line 18 and the marker 20 on the surface material 1a side, and the second laser processing device 104 forms the cut line 18 and the marker 20 on the back surface material 1b side. Is formed.
In the present embodiment, it is preferable to form the cut line 18 and the marker 20 with an optical reflection type laser marker. At this time, the light of the mirror is formed so that the cut line 18 and the marker 20 are formed almost simultaneously in the same process. If the axial movement is programmed, the relative positional relationship between the cut line 18 and the marker 20 can be easily made constant.

Finally, cutting is performed by the cutting device 105, and cutting is performed along the contour line of the refill pouch 10, whereby the refill pouch 10 is manufactured.
In the present embodiment, two refill pouches 10 are manufactured at the same time in order to improve manufacturing efficiency. However, the refill pouches 10 may be manufactured one by one.

In the refill pouch 10 manufactured as described above, the marker 20 whose relative positional relationship with the cutoff line 18 is constant is formed. Therefore, whether or not the marker 20 is formed within a predetermined range. Thus, it is determined whether or not the cut line 18 is formed at a predetermined position, and it is possible to easily know the occurrence of a defective product.
Further, since the cut line 18 and the marker 20 are formed on both the front surface side and the back surface side of the nozzle portion 16 of the refill pouch 10, the direction of displacement of the cut line 18 differs between the front surface side and the back surface side. Further, it is possible to easily find a case where the opening property is deteriorated by the intersection of the cut line 18 formed on the front surface side and the cut line 18 formed on the back surface side.

Therefore, according to the manufacturing method of the refill pouch according to the present embodiment, it is possible to easily know the occurrence of a defective product due to the positional deviation of the cutoff line 18, and continue the manufacturing without noticing the occurrence of the defective product, It is possible to effectively avoid a situation in which a large number of defective products are generated.
That is, at the initial stage when a defective product has started to be generated, it is possible to easily know the occurrence of a defective product. At that time, the production is stopped and the raw material 1 is set again. Can be minimized.

  Although the present invention has been described with reference to the preferred embodiment, it is needless to say that the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention. .

  For example, the applicant previously proposed in Japanese Patent Application Laid-Open No. 2004-67142, Japanese Patent Application Laid-Open No. 2004-90932, and the like, and the three-dimensional processing for improving the content pouring property is applied to the nozzle portion 16 and the vicinity thereof. Various configurations applicable to this type of refillable pouch can be arbitrarily added.

  Further, the shape of the cut line 18 is not limited to the curved shape as in the above-described embodiment, and various shapes such as a linear shape, a V shape, or a combination of these and a curve may be adopted. it can.

  As described above, the refill pouch according to the present invention is suitably used as a refill container for detergents, bleaches, softeners, laundry glue, shampoos, rinses, and the like.
