[0001] Related application information of division

[0002] This case is a divisional application. The parent application of this divisional application is the invention patent application filed on April 16, 2019, with application number 201980026122.9 and invention title "Outer Bag for Product Storage and Manufacturing Method Thereof and Bag Body Supply Method". Technical Field

[0003] This invention relates to a tubular outer bag, and more particularly to a tubular outer bag that wraps multiple articles in a fixed relative position to form a single unit. Furthermore, this invention relates to an article storage bag that uses a tubular outer bag to wrap articles, and further to a rolled or folded article of an article storage bag obtained by rolling, twisting, or folding the article storage bag in a flat cross-section. Furthermore, this invention relates to a method for manufacturing these items and a method for supplying a bag body containing articles to be removed from the article storage bag. Furthermore, this invention relates to a tubular outer bag with a fitting and a method for using the tubular outer bag. Background Technology

[0004] Generally, the form of goods directly packaged for sale is called primary packaging. The form of goods that are repackaged in boxes or bags in specified quantities in primary packaging is called secondary packaging. Goods are delivered to consumers in primary or secondary packaging. The form of goods in secondary packaging being placed in specified quantities into packing boxes, etc., for bulk processing, warehousing, and transportation is called tertiary packaging. Furthermore, sometimes, goods in primary packaging are also considered tertiary packaging without undergoing secondary packaging.

[0005] For example, there is a technique in which the cylindrical side of a small roll (equivalent to a "product") is wound onto a packaging film, and the side of the packaging film is heat-sealed, thereby sealing the packaging film located on the upper and lower surfaces of the cylinder and heat-sealing it to package the small roll once (for example, see Figures 25 to 29 of Patent Document 1).

[0006] Furthermore, for bag manufacturers, the goods to be sold are the bag body, which serves as packaging material (for example, see Patent Document 2). Therefore, in this specification, when the bag body, which serves as packaging material, is a good for sale, it is sometimes referred to as an "article" to distinguish it from goods that are not packaging materials (ordinary goods, hereinafter also referred to as non-packaging material goods). In addition, the packaging that wraps the bag body is sometimes referred to as an outer bag.

[0007] Before the bag with the gusset that accommodates the non-packaged material goods is displayed in the retail store, it is usually first subjected to the following processes, i.e., (1) a bag-making process in which a bag maker manufactures a bag body and then accommodates the bag body in an outer bag; (2) a transport process 1 in which the bag body is delivered to a manufacturer of the non-packaged material goods; (3) a bag-provision process in which the bag body is taken out of the outer bag; (4) a filling process in which the non-packaged material goods are filled into the bag body; and (5) a transport process 2 in which the non-packaged material goods filled into the bag body are transported to the retail store for delivery to ordinary consumers.

[0008] The conventional bag-making process is performed in the following order. That is, the product, i.e., the bag with the gusset, manufactured by the bag-making machine is temporarily stored in a container such as a tray, and a bundling operation of bundling a fixed number of the product, i.e., the bag with the gusset, by hand is performed by a person. The product, i.e., the bag with the gusset, bundled with the fixed number of the product is fixed by a bundling mechanism such as a rubber band, and then put into an outer bag with the gusset, after which the gusset of the outer bag is closed. Further, a plurality of the outer bags with the gusset are packed in a case. The case is shipped after being covered with a waterproof film to prevent attachment of dust, dirt, or water immersion. These processes are all performed by hand by a person.

[0009] Further, the conventional bag-provision process is performed in the following order. That is, the manufacturer of the non-packaged material goods performs the following operations in order to fill the non-packaged material goods into the bag with the gusset, i.e., peels the waterproof film, takes out the outer bag from the case, releases the engagement of the gusset of the outer bag, takes out the bundled bag with the gusset, and removes the bundling mechanism such as the rubber band that performs the bundling, so as to restore the bag with the gusset to the individual state. These processes are also performed by hand by a person.

[0010] Further, the conventional filling process is performed in the following order. That is, the respective bags with the gusset are supplied to a bag body supply portion of a filling machine. This process is also performed by hand by a person. The bag with the gusset taken out one by one from the bag body supply portion of the filling machine is opened to fill the non-packaged material goods. This process is performed by the filling machine.

[0015] [PROBLEMS TO BE SOLVED BY THE INVENTION]

[0016] However, in the bagging process, the work speed or accuracy at the time of bagging depends on the ability of each bagger, and thus the speed of the packaging bag production line needs to be adjusted according to the processing ability of each person, and in addition, the bagger needs to take a break. As a result, the productivity is reduced, and in addition, the productivity is easily unstable, and the production efficiency is poor. In addition, the bags stored in the pallet are limited in the number of storage pieces depending on the difference in the storage place or the instability of the stacking, and a wide space is required. Also, when the bundled bags are put into the outer bag, the rubber band needs to be fixed, and when put into the outer bag, the fitting piece needs to be opened and closed, and in addition, the bagging, waterproof film application needs to be performed, and these operations take time and labor.

[0017] In addition, in the bag supply process, the bagged outer bag with a waterproof film is taken out and the engagement of the fitting piece is released, and the bag with the fitting piece is restored to the respective state by removing the rubber band or the like, but these operations need to be performed by hand by a person. In particular, the bag with the fitting piece has a curved mark due to the rubber band or the like, and has to be subjected to an operation to restore it to a flat state, and these operations are also performed by hand by a person. Further, there is a case where the bag with the fitting piece that has come into contact with the rubber band or the like is wrinkled, and sometimes has a hole. In this way, it is easy to frequently occur operation errors or product waste. Further, whenever the bag with the fitting piece is placed in the filling machine is ended, the next outer bag needs to be returned to the fitting piece opening process and the operation is repeated by hand by a person, and in this way, time and labor will be consumed. As a result, in addition to the high labor cost and high cost, operation errors and the like are also inevitable. In addition, it is difficult to secure human resources due to a shortage of manpower, and thus the cost becomes higher.

[0018] Further, the outer bag itself needs to be bagged, and thus like the bag product, time and cost are consumed. In addition, various outer bags need to be stored with a waterproof film, and a warehouse needs to be managed, and thus the cost is very high, and time is also consumed.

[0019] In addition, the waterproof film, the shipping box, and the outer bag are discarded after the filling process, and thus a large amount of resources is wasted.

[0020] In addition, the bundling, the outer bag loading, the bagging, the opening of the bag, and the opening of the outer bag are performed by hand by a person, and thus there is also a concern about the attachment of dirt by the person.

[0021] Therefore, the present application aims to provide a bag body with a fitting member, a bag body, an article storage bag, a rolled article storage bag, a manufacturing method thereof, and a bag body supply method, which are (1) capable of achieving high speed of a packaging bag production line by seeking labor saving of human work, and capable of achieving stabilization of production speed, reduction of manufacturing waste caused by human work errors, and suppression of quality reduction of bag bodies caused by human work errors, and (2) capable of preventing cost increase caused by bag making and storage of the bag body and saving management effort.

Thus, from the viewpoint of the filler, the bag making machine does not need to be maintained, and the production line can be substantially reproduced. Furthermore, from the viewpoint of a bag maker, a bundling operation of the bag body does not need to be performed, and further, a quality inspection process accompanying the bundling operation can also not be needed.

[0049] Furthermore, in the coiled product of the outer bag for products, air in the outer bag is removed by coiling, and thus the contact state of the inner wall of the outer bag with the bag body and the contact state of the bag bodies with each other do not shift even during transportation, and thus when the bag body is opened and taken out, the state after the bag body is filled can be reproduced as it is.

In the present embodiment, the bag 1 with the fitting member has at least one opening portion 6. In the case where the opening portion 6 is one, the base material becomes one belt-shaped film by unfolding the opening portion. Figure 2 As shown in Figs. 1 and 2, the opening portion 6 is provided on the base material 5 along the length direction X of the cylinder. In the present embodiment, the bag 1 with the fitting member has at least one opening portion 6. In the case where the opening portion 6 is one, the base material becomes one belt-shaped film by unfolding the opening portion. Figures 1-7 As shown in Figs. 1 and 2, the opening portion 6 is provided on the base material 5 along the length direction X of the cylinder. In the present embodiment, the bag 1 with the fitting member has at least one opening portion 6. In the case where the opening portion 6 is one, the base material becomes one belt-shaped film by unfolding the opening portion.

[0106] As shown in Figs. 1 and 2, the opening portion 6 is provided on the base material 5 along the length direction X of the cylinder. In the present embodiment, the bag 1 with the fitting member has at least one opening portion 6. In the case where the opening portion 6 is one, the base material becomes one belt-shaped film by unfolding the opening portion. Figure 1 As shown in Figs. 1 and 2, the opening portion 6 is provided on the base material 5 along the length direction X of the cylinder. In the present embodiment, the bag 1 with the fitting member has at least one opening portion 6. In the case where the opening portion 6 is one, the base material becomes one belt-shaped film by unfolding the opening portion. Figure 2 As shown in Figs. 1 and 2, the opening portion 6 is provided on the base material 5 along the length direction X of the cylinder. In the present embodiment, the bag 1 with the fitting member has at least one opening portion 6. In the case where the opening portion 6 is one, the base material becomes one belt-shaped film by unfolding the opening portion. Figure 4 As shown in Figs. 1 and 2, the opening portion 6 is provided on the base material 5 along the length direction X of the cylinder. In the present embodiment, the bag 1 with the fitting member has at least one opening portion 6. In the case where the opening portion 6 is one, the base material becomes one belt-shaped film by unfolding the opening portion. Figure 4The convex base portion 4al and the concave base portion 4bl of the fitting member 4 are adhered to the inner wall surface of the base material 5. Further, as shown in Figure 5 The fitting member 4 can also have a collet structure having a concave portion 4d extending in the length direction X of the cylinder and a convex portion 4c extending in the length direction X of the cylinder, which is closed by engaging the convex portion 4c in the concave portion 4d. Figure 5 The convex portion 4c and the concave portion 4d of the fitting member 4 shown in the drawing are integrally formed with the base material 5. In the present embodiment, the fitting member 4 is not limited to Figure 4 and Figure 5 The collet structure shown in the drawing can also have a structure in which the concave portions engage each other.

[0107] The bag 1 with the fitting member is wound into a cylinder, twisted, or folded in a state in which the cross section is flat. The state in which the cross section is flat means a state in which the inner wall surfaces of the cylindrical shape face each other and are in contact. The winding into a cylinder includes a winding around a core, a coreless winding, and the like. In the state in which the cross section is flat, the space in the cylinder is deaerated, and thus the bag 1 with the fitting member is in a belt shape. In this case, it is preferable to wind the bag 1 with the fitting member in a state in which the flat outer wall surfaces face each other. The volume of the bag 1 with the fitting member can be reduced. Further, even in a state in which the bag 1 with the fitting member is folded in a zigzag shape, the space in the cylinder is deaerated in the state in which the cross section is flat, and thus the bag 1 with the fitting member is in a belt shape. In this case, it is preferable to fold the bag 1 with the fitting member in a state in which the flat outer wall surfaces face each other. The volume of the bag 1 with the fitting member can be reduced.

[0108] (Article Storage Outer Bag: First Example)

[0109] Next, the article storage outer bag 100 (first example) of the present embodiment will be described with reference to Figures 1-3 , Figure 6 and Figure 7 The article storage outer bag 100 of the present embodiment is an outer bag in which a plurality of bag bodies 3, which are stacked in a row in a manner in which the bag bodies (pl, p2, p3, p4,..., pn) as articles are overlapped, are integrated while being wrapped with the bag 1 with the fitting member, and the stacked state of the bag bodies is maintained. The bag 1 with the fitting member is formed of a resin film as the base material 5, has a cylindrical shape extending continuously in the length direction X of the cylinder with the same inner diameter, has at least one opening portion 6 opened in the length direction X of the cylinder, and has the fitting member 4 engaged along the edge 6a of the opening portion 6 on the inner wall side of the base material 5.

[0110] In the product storage outer bag 100 (first example) of the present embodiment, the product storage outer bag 100 is preferably formed by stacking a plurality of bag bodies 3 in a state of being partially overlapped in a row on a base material 5 of a resin film for an outer package provided in a flat sheet shape, folding the base material 5 to wrap the plurality of bag bodies 3 with the base material 5, and integrating the bag bodies 3 in a state of being stacked while the bag bodies 3 are held.

[0111] The product storage outer bag 100 of the present embodiment stores a plurality of bag bodies as products in the inside of the outer package of the bag body 3. Figure 6 and Figure 7 As shown in FIG. 1, the bag body pi as a product is a plastic resin bag body having an opening portion 8 and a storage portion 7, and a chuck 9 is provided at the end portion of the opening portion 8. The chuck 9 has a fitting structure, for example, the same structure as the fitting member 4 of the bag body 3, and is freely opened and closed. The bag bodies p2, p3, p4,..., and pn as products are bag bodies having the same structure as the bag body pi. The bag bodies as products (pi, p2, p3, p4,..., and pn) have a flat structure, and thus, as shown in FIG. 2, a plurality of bag bodies 3 can be stacked in a state of being partially overlapped in a row. Figure 3 Here, the plurality of bag bodies 3 can be arranged in a continuous row along the length direction X of the bag body 3, or can be arranged intermittently, that is, in a row having a portion where the bag bodies 3 are not arranged. The intermittent arrangement is preferably an arrangement in which, for example, a specific number of bag bodies are stacked in a state of being partially overlapped in a row, a gap is provided, and then the same number of bag bodies are stacked in a state of being partially overlapped in a row, and then a gap is provided again. In this case, the number of bag bodies can be easily confirmed. In the present embodiment, the plurality of bag bodies 3 stacked in a state of being partially overlapped in a row are integrated by being formed in the product storage outer bag 100, and thus, are sometimes simply referred to as "a plurality of bag bodies 3" or "bag bodies 3".

[0112] As shown in FIG. 3, the product storage outer bag 100 is formed by wrapping the plurality of bag bodies 3 with the bag body 3. Figure 2 Here, the width of the bag body 3 when the plurality of bag bodies 3 are housed is preferably slightly larger than the width of the plurality of bag bodies 3, and is preferably, for example, 1 to 10 mm larger. In this case, the bag body 3 preferably has a holding force to the extent that the arrangement of the plurality of bag bodies 3 is not deformed when the fitting member 4 is closed. The plurality of bag bodies 3 can be further integrated while being held in a stacked state, and the inside of the bag body 3 does not enter excess air, and thus, the increase in volume can be suppressed. The bag body 3 is integrated in a state of containing the plurality of bag bodies 3 by engaging the fitting member 4.

[0113] The article storage outer bag 100 can not only handle a plurality of bag bodies 3 in batches when transporting or storing, or both, but also can fix the arrangement state of the bag bodies sequentially manufactured from a bag making machine, so that a production line can be substantially reproduced even if the bag making machine and the filling machine are located at different places.

[0114] The bag body 3 is wrapped with the bag body 3 in a clamshell fitting form, and the engagement of the engagement member 4 is easily performed. Therefore, the device can be manufactured with a simple configuration. Further, when the engagement of the engagement member 4 is released, the opening form can be used. More preferably, as shown in Figure 2 Figure 2 The engagement member 4 is located at the central portion of the stacking surface of the bag body 3. This can more stably perform the engagement and release operations, and can more stably roll into a cylinder, twist, or fold.

[0115] (Article storage outer bag: second example)

[0116] Next, the article storage outer bag 200 (second example) of the present embodiment will be described with reference to Figure 8 and Figure 9 The article storage outer bag 200 of the present embodiment preferably has an engagement member 14 located at either side end side of the bag body 13 and engaged. As shown in Figure 9 The article storage outer bag 200 is the same as the article storage outer bag 100 except for the position of the engagement member 14. That is, the article storage outer bag 200 integrates the bag body 13 by wrapping a plurality of bag bodies 13 with the bag body 3 and engaging the engagement member 14. In the article storage outer bag 200, the adhesion of the base material 15 to the bag body 13 is higher. In the article storage outer bag 200, as in the case of the article storage outer bag 100, the width of the bag body 3 when storing a plurality of bag bodies 13 is preferably slightly larger than the width of the plurality of bag bodies 13, and is preferably, for example, 1 to 10 mm larger. Figure 9 In the article storage outer bag 200, the opening portion 16 is provided at the left end portion and the left edge becomes the edge 16a of the opening portion 16 by the engagement member 14 being located at the left end side of the bag body 3. Figure 9 In the article storage outer bag 200, the engagement member 14 is located at the left end side of the bag body 3, but can be located at the right end side. The article storage outer bag 200 of the present embodiment is a form in which the bag bodies (p1, p2, p3, p4,..., pn) are arranged in order by gravity when the bag bodies are put into the bag body 3, and the bag bodies 13 are more neatly arranged in the article storage outer bag 200 after the bag bodies 13 are integrated with the bag body 3.​

[0117] (Product storage bag: third example)

[0118] Next, refer to Figure 10 and Figure 11 The article storage outer bag 300 of this embodiment (third example) will be described. In the article storage outer bag 300 of this embodiment, the cylindrical outer bag 21 with fittings preferably has two fittings 24a and 24b, and the fittings 24a and 24b are located on the left end side and the right end side of the bag body 23 respectively and engage with each other. Figure 11 As shown, the outer bag 300 for storing products is the same as the outer bag 100, except that it has two fittings 24a and 24b, and their positions are different. That is, the outer bag 300 for storing products wraps multiple bag bodies 23 with a cylindrical outer bag 21 with fittings, and the fittings 24a and 24b are engaged, so that the cylindrical outer bag 21 with fittings is integrated in the state of containing the bag bodies 23. In the outer bag 300 for storing products, as in the outer bag 200 for storing products, the substrate 25 has a higher adhesion to the bag bodies 23. In the outer bag 300 for storing products, also as in the case of the outer bag 100 for storing products, the width of the cylindrical outer bag 21 with fittings when containing multiple bag bodies 23 is preferably slightly larger than the width of the multiple bag bodies 23, preferably for example, 1 to 10 mm larger. Figure 11 In this embodiment, the fitting member 24a is located on the left end of the cylindrical outer bag 21 with the fitting member, so that the opening 26 is located on the left end, and the left edge becomes the edge 26a of the opening 26. Furthermore, the fitting member 24b is located on the right end of the cylindrical outer bag 21 with the fitting member, so that the opening 27 is located on the right end, and the right edge becomes the edge 27a of the opening 27. In this embodiment, the product storage outer bag 300 can be opened by disengaging the fitting members 24a and 24b respectively, by dividing the base material 25 of the cylindrical outer bag 21 with the fitting member into base material 25a (also called another base material 25a) and base material 25b (also called one base material 25b), thus facilitating the removal of the bag body 23.

[0119] (Product storage bag: Example 4)

[0120] Next, refer to Figure 12 and Figure 13An article storage outer bag 400 (fourth example) of the present embodiment will be described. The article storage outer bag 400 of the present embodiment is an outer bag closed by adhesion or heat fusion. The article storage outer bag 400 of the present embodiment is an article storage outer bag in which a plurality of bag bodies 33, which are stacked in a row in a manner that bag bodies (pl, p2, p3, p4,..., pn) as articles are overlapped as a part of the bag bodies, are integrated while being wrapped with a cylindrical outer bag 31 for outer packaging and the stacked state of the bag bodies is maintained, the cylindrical outer bag 31 is formed in a cylindrical shape extending continuously in the same inner diameter along the length direction X of the cylinder with a resin film as a base material 35, has at least one cutout portion 36 along the length direction X of the cylinder, and the inner walls of the base material 35 are adhered or heat fused to each other or the inner wall and the outer wall along the edge 36a of the cutout portion 36.

[0121] The article storage outer bag 400 of the present embodiment stores a plurality of bag bodies as articles inside the cylinder of the cylindrical outer bag 31 for outer packaging. The bag bodies as articles (pl, p2, p3, p4,..., pn) are the same as the bag bodies (pl, p2, p3, p4,..., pn) described in the article storage outer bag 100. Figure 6 Figure 7 In addition, the state of the plurality of bag bodies 33 is the same as the state of the plurality of bag bodies 3 in the article storage outer bag 100.

[0122] The article storage outer bag 400 is as shown in FIG. 9. Figure 13 ​As shown, a plurality of bags 33 are wrapped in a cylindrical outer bag 31. In this case, the inner walls 38a and 38b of the substrate 35 in the cylindrical outer bag 31 are bonded or heat-fused together to form a joint 39. Here, the width of the cylindrical outer bag 31 containing the plurality of bags 33 is preferably slightly larger than the width of the plurality of bags 33, preferably, for example, 1 to 10 mm larger. The degree to which the cylindrical outer bag 31 secures the plurality of bags 33 preferably has a holding force sufficient to prevent deformation of the arrangement of the plurality of bags 33. This maintains the stacked state of the bags 33, further integrating them, and prevents excess air from entering the cylinder, thus suppressing volume increase. The cylindrical outer bag 31 is integrated while containing the bags 33 by bonding or heat-fusioning the inner walls 38a and 38b of the substrate 35 together. Alternatively, the tubular outer bag 31 can also be integrated (not shown) while containing the bag body 33 by bonding or heat-sealing the inner wall 38a and outer wall 38d of the substrate 35 together. In this embodiment, bonding is performed using an adhesive such as a paste or tape, and heat-sealing is performed using heat sealing, ultrasonic, high frequency, spot sealing, instant sealing machine, or laser. The cut portion 36 refers to the discontinuous portion in the tubular outer bag 31 located at the joint portion 39 in the direction surrounding the main body of the substrate 35. The cut portion 36 can be provided outside the joint portion 39 of the film so that opposing films are not bonded to each other, or it can be omitted. The cut portion 36 in the tubular outer bag 31 can be not only for Figure 13 The single form shown can also consist of two or more. For example, it can also be in the following form (not shown), namely, respectively in the equivalent of Figure 11 Cutouts are provided at the positions of the fittings 24a and 24b, and a total of two cutouts are provided.

[0123] The outer bag 400 for product storage is the same as that for outer bags 100, 200 and 300. It can not only process multiple bags 33 in batches when handling, storing or doing both, but also fix the arrangement of bags manufactured sequentially from the bag making machine. Therefore, even if the bag making machine and the filling machine are in different places, the production line can be substantially reproduced.

[0124] The tubular outer bag 31 can be sequentially removed by cutting the substrate 35 along the length X of the tube. The cutting point is preferably the cut portion 36. When opening the tubular outer bag 31, in addition to... Figure 13 In addition to the method of peeling off the joint 39 to open the seal, another method is to provide a vulnerable part such as a scratched part or a half-cut part on the film of the tubular outer bag 31, and open the seal from the vulnerable part.

[0125] (Rolled-up items for storing products)

[0126] The rolled product 50 in the outer bag for storing the product in this embodiment Figure 14and Figure 15 The product storage outer bag 100, 200, 300, 400 of the present embodiment is wound into a cylindrical shape in a state where the cross section is flattened. Figure 14 In the present embodiment, as one form of winding into a cylindrical shape, a form in which the product storage outer bag 100, 200, 300, 400 is wound around the winding shaft 51 is shown. Figure 14 and Figure 15 In the present embodiment, winding is performed by rotating the winding shaft around the rotation axis 95. It is also possible to provide a form in which, instead of the winding shaft 51, winding is performed around a cylindrical core (not shown), or a form in which winding is performed without a core (not shown). Further, the product storage outer bag 100, 200, 300, 400 can be twisted or folded in a state where the cross section is flattened (not shown) instead of being wound into a cylindrical shape in a state where the cross section is flattened. Here, the state where the cross section is flattened refers to a state in which the flat surfaces of the plurality of bag bodies 3, 13, 23, 33 housed in the product storage outer bag 100, 200, 300, 400 come into contact with the inner wall surface of the cylindrical base material 5, 15, 25, 35, and the cross section assumes an elongated shape reflecting the cross-sectional shape of the plurality of bag bodies 3, 13, 23, 33. Figure 15 In the present embodiment, a form in which the cross section of the product storage outer bag 100, 200, 300, 400 is flattened, for example, into a substantially rectangular shape, is shown. In the product storage outer bag 100 having the fitting member 4, if wound into a cylindrical shape, the fitting member 4 assumes a lying state, that is, a state in which it is bent in a manner in which the opening portion 6 straddles the base material 5. The product storage outer bag 100, 200, 300, 400 makes the space inside the cylinder into a degassed state by being flattened in cross section, and thus assumes a band-like shape, at which time, it is preferable to be wound in a manner in which the outer wall surfaces of the product storage outer bag 100, 200, 300, 400 come into contact with each other. This makes it possible to reduce the volume of the product storage outer bag 100, 200, 300, 400 after winding. Further, in a folded form, that is, a form in which it is zigzag folded, the product storage outer bag 100, 200, 300, 400 makes the space inside the cylinder into a degassed state by being flattened in cross section, and thus assumes a band-like shape, at which time, it is preferable to be folded in a manner in which the outer wall surfaces of the product storage outer bag 100, 200, 300, 400 come into contact with each other. This makes it possible to reduce the volume of the product storage outer bag 100, 200, 300, 400 after folding.

[0127] (Method for manufacturing a wound product of a product storage outer bag)

[0128] Next, with reference to Figure 16A manufacturing method of the product storage outer bag of the present embodiment will be described. The manufacturing method of the product storage outer bag of the present embodiment is a manufacturing method of a product storage outer bag in which a plurality of bag bodies 3, which are stacked in a row in a manner that portions of the bag bodies (p1, p2, p3, p4,..., pn) as products overlap, are wrapped with a tubular outer bag 1 with a fitting member for outer packaging, and the stacked state of the bag bodies 3 is maintained, and the manufacturing method is a manufacturing method of a product storage outer bag in which the tubular outer bag with a fitting member is formed in a cylindrical shape that continuously extends in the same inner diameter along the length direction X of the cylinder with a resin film as a base material 5, has at least one opening portion 6 that opens along the length direction X of the cylinder, and has a fitting member 4 along the edge 6a of the opening portion on the inner wall side of the base material 5, and has a configuration in which the opening portion 6 is closed by engagement of the fitting member 4, and the manufacturing method has: a first step of preparing the tubular outer bag with a fitting member 1 for outer packaging; a second step of releasing the engagement of the fitting member 4 and bringing the tubular outer bag with a fitting member 1 for outer packaging into an unfolded state; a third step of continuously or intermittently stacking the bag bodies in a row on the base material 5 in a manner that portions of the bag bodies (p1, p2, p3, p4,..., pn) overlap along the length direction Y of the base material 5; and a fourth step of moving the base material 5 on which the plurality of bag bodies 3 are placed along the length direction Y of the base material 5 while folding the base material 5 to wrap the plurality of bag bodies 3 with the base material 5, and bringing the fitting member 4 into engagement to obtain the product storage outer bag 100.

[0129] (First manufacturing method)

[0130] In the first manufacturing method, the tubular outer bag with a fitting member for outer packaging and the product storage outer bag are the tubular outer bag with a fitting member 1 for outer packaging and the product storage outer bag 100 illustrated in FIG. 1, and the bag body is the bag body p1 illustrated in FIG. 2, and the product storage outer bag 100 is wound on the same spool as the spool 51 illustrated in FIG. 3 and FIG. 4, and further, the length direction Y of the base material 5 is the same direction as the length direction X of the cylinder with the base material 5 as a reference. Figures 1-5 Figure 6 Figure 7 Figure 14 Figure 15

[0131] (First step)

[0132] An outer bag winding product 53 of the tubular outer bag with a fitting member for outer packaging 1 is prepared that is wound on a spool 52. The tubular outer bag with a fitting member for outer packaging 1 is wound on the spool 52 in a flat state in which the cylinder is deformed in a manner that the fitting member 4 is engaged and the fitting member 4 is positioned at the side end. The tubular outer bag with a fitting member for outer packaging 1 is unwound in the direction of the length direction X of the cylinder and is fed out to a dancer roll 61a and a pinch roll 62a. In addition, in a case where the fitting member 4 is separated from the base material 5, the first step includes a process 1A of preparing a tubular film or a half-cut film to which the fitting member 4 is not attached, and a process 1B of installing a fitting member tape on the tubular film or the half-cut film.​​​​​

[0133] (2nd process)

[0134] The engagement of the fitting 4 is released, and the bag 1 with the fitting is brought to an unfolded state. That is, the bag 1 with the fitting is unfolded by the pawl guide rollers 63a, 63c releasing the engagement of the fitting 4 of the outer bag 1 with the fitting for the outer package by the pinch roller 62a, and is fed to the pinch roller 62b in a state where the overlapping of the base material 5 is removed.

[0135] (3rd process)

[0136] The bag bodies (pl, p2, p3, p4,..., pn) are placed on the base material 5 in a flat sheet shape. Specifically, the bag bodies are continuously or intermittently stacked in a row on the base material 5 in a state where the base material 5 is unfolded in the bag 1 with the fitting for the outer package in a manner that a part of the bag bodies (pl, p2, p3, p4,..., pn) overlap in the length direction Y of the base material 5. Figure 16 In the drawing, a state where the bag bodies are stacked in a row in a manner that the bag bodies (pl, p2, p3, p4,..., pn) are continuous is shown. Here, the bag bodies (pl, p2, p3, p4,..., pn) are placed on the conveyer 65 located on the downstream side of the bag making machine (not shown) one by one. The bag bodies, for example, the bag bodies p4, p5, p6, p7 on the conveyer 65 are placed on the base material 5 in order.

[0137] (4th process)

[0138] While the base material 5 on which the plurality of bag bodies 3 are placed is moved in the length direction Y of the base material 5, the plurality of bag bodies 3 are wrapped with the base material 5 by the pawl guide roller 63b, and the product storage outer bag 100 is obtained by engaging the fitting 4. The product storage outer bag 100 whose fitting 4 is engaged is preferably fed to the contact roller 64, the pinch roller 62c, and the dancer roller 61b in a state where the opening 6 is laid horizontally near the root of the fitting 4. The inside of the product storage outer bag 100 is degassed, and thus the volume is reduced.

[0139] (5th process)

[0140] The product storage outer bag 100 is wound on the reel 51 in a state where the cross section is flat, and the wound product 50 of the product storage outer bag is obtained. Figure 16 In the drawing, the product storage outer bag 100 is wound in a cylindrical shape, but the product storage outer bag 100 can be twisted or folded in a state where the cross section is flat.

[0141] In the first manufacturing method, the bag 1 with the fitting member has one fitting member 4, in the second step, the base material 5 is spread horizontally, in the fourth step, the fitting member 4 is arranged on the stacking surface of the bag body 3, and the fitting member 4 is engaged. According to the first manufacturing method, the bag 1 can be easily wrapped around the bag body 3 in a palm-pressing engagement, and the fitting member 4 can be easily engaged. Therefore, the product can be manufactured by a simple device. Further, when the fitting member 4 is disengaged, the bag 1 can be easily opened.

[0142] (Second manufacturing method)

[0143] Next, the second manufacturing method of the product storage outer bag of the present embodiment will be described with reference to Figure 17 The second manufacturing method of the product storage outer bag of the present embodiment will be described with reference to Figure 8 and Figure 9 The bag body is the bag body pi shown in Figs. 1 and 2, and the product storage outer bag 200 is wound around the same winding shaft as the winding shaft 51 shown in Figs. 1 and 2 (the winding shaft is omitted in Fig. 1). Further, the length direction Y of the base material 15 is the same direction as the length direction X of the cylinder with the base material 15 as a reference. Figure 6 and Figure 7 The bag body is the bag body pi shown in Figs. 1 and 2, and the product storage outer bag 200 is wound around the same winding shaft as the winding shaft 51 shown in Figs. 1 and 2 (the winding shaft is omitted in Fig. 1). Further, the length direction Y of the base material 15 is the same direction as the length direction X of the cylinder with the base material 15 as a reference. Figure 14 and Figure 15 The bag body is the bag body pi shown in Figs. 1 and 2, and the product storage outer bag 200 is wound around the same winding shaft as the winding shaft 51 shown in Figs. 1 and 2 (the winding shaft is omitted in Fig. 1). Further, the length direction Y of the base material 15 is the same direction as the length direction X of the cylinder with the base material 15 as a reference. Figure 17 (First step)

[0144] The same as the first manufacturing method.

[0145] The first step is omitted in the present embodiment. In the case where the fitting member 14 is separated from the base material 15, the first step includes a step 1A of preparing a cylindrical film or a semi-cut film to which the fitting member 14 is not adhered, and a step 1B of mounting a fitting member tape on the cylindrical film or the semi-cut film. Figure 17 (Second step)

[0146] The bag 1 with the fitting member is spread in a U-shaped or V-shaped manner in the cross section of the length direction Y of the base material 15, the engagement of the fitting member 14 is released, and the bag 1 with the fitting member is brought to an unfolded state.

[0147] (Third step)

[0148]

[0149] ​The bag bodies are preferably placed in the inside of the U-shaped or V-shaped base material with either the left or right side end side of the bag body facing downward. The bag bodies are aligned by gravity, and thus the bag bodies are more neatly arranged in the product storage outer bag. That is, the bag body (pl, p2, p3, p4,..., pn) is continuously or intermittently stacked in a row along the length direction Y of the base material 15 in the inside of the U-shaped or V-shaped base material 15 by the position alignment device 68 in a manner in which a portion of the bag body (pl, p2, p3, p4,..., pn) overlaps, with the tubular outer bag 11 with the belt fitting member unfolded. Figure 17 In the drawing, the bag bodies are stacked in a row in a manner in which the bag bodies (pl, p2, p3, p4,..., pn) are continuous. Here, the bag bodies (pl, p2, p3, p4,..., pn) are placed on the conveyor 65 on the downstream side of the bag making machine (not shown) one by one and conveyed. The bag bodies, such as the bag bodies p4, p5, p6, and p7, on the conveyor 65 are sequentially placed in the inside of the base material 15.

[0150] (4th process)

[0151] While the base material 15 with the plurality of bag bodies 13 placed in the inside is moved along the length direction Y of the base material 15, the plurality of bag bodies 13 is wrapped with the base material 15 by the claw abutting member 67, and the fitting member 14 is engaged to obtain the product storage outer bag 200. In the product storage outer bag 200 after the fitting member 14 is engaged, the inside of the product storage outer bag 200 is degassed, and thus the volume is reduced.

[0152] (5th process)

[0153] The product storage outer bag 200 is wound on a reel in a state in which the cross section is flat to obtain a wound product 54 of the product storage outer bag. Figure 17 In the drawing, the product storage outer bag 200 is wound in a tubular shape, but the product storage outer bag 200 can be twisted or folded in a state in which the cross section is flat.

[0154] (Third manufacturing method)

[0155] Next, the third manufacturing method of the wound product of the product storage outer bag according to the present embodiment will be described with reference to Figure 18 The third manufacturing method of the product storage outer bag according to the present embodiment will be described. Here, the outer packaging tubular outer bag with the belt fitting member and the product storage outer bag are the tubular outer bag 21 with the belt fitting member and the product storage outer bag 300 described in Figure 10 and Figure 11 The bag body is the bag body pl described in Figure 6 and Figure 7 The product storage outer bag 300 is wound on the same reel as the reel 51 described in Figure 14 and Figure 15 Furthermore, the length direction Y of the base material 25 is the same direction as the length direction X of the tubular shape with the base material 25 as a reference.

[0156] (Step 1)

[0157] An outer bag product 55 of the bag-in-bag-out type outer bag 21 with fitting members for outer packaging is prepared to be wound on a winding shaft 56. The bag-in-bag-out type outer bag 21 with fitting members for outer packaging has two fitting members, and is wound on the winding shaft 56 in a flat state in which the bag is deformed so that the fitting members 24a, 24b engage and are located at both end sides, respectively. The bag-in-bag-out type outer bag 21 with fitting members for outer packaging is unwound and fed to the claw opening member 66 in the direction of the length X of the bag. In addition, in the case where the fitting members 24a, 24b are separated from the base material 25, the first step includes a step 1A of preparing a bag-shaped film or a half-cut film to which the fitting members 24a, 24b are not attached, and a step 1B of mounting a fitting member tape on the bag-shaped film or the half-cut film.

[0158] (Step 2)

[0159] With respect to the bag-in-bag-out type outer bag 21 with fitting members for outer packaging that has passed through the claw opening member 66, one of the base materials 25b that has been divided into two by releasing the engagement of the fitting members 24a, 24b is spread horizontally above the other base material 25a. The one base material 25b is fed to the nip roller 62a. The other base material 25a is also fed to a nip roller (not shown).

[0160] (Step 3)

[0161] It is preferable that the one base material 25b be a flat sheet, and that the bag bodies (pl, p2, p3, p4,..., pn) be placed on the one base material 25b in such a manner that the fitting members 24a, 24b located at both end sides in the width direction of the one base material 25b are located at the left end side and the right end side of the bag bodies (pl, p2, p3, p4,..., pn), respectively. That is, the one base material 25b is spread, and the bag bodies are continuously or intermittently stacked in a row in such a manner that a portion of the bag bodies (pl, p2, p3, p4,..., pn) overlap each other in the length direction Y by the position alignment device 68. Figure 18 In the drawing, a state in which the bag bodies are stacked in a row in such a manner that the bag bodies (pl, p2, p3, p4,..., pn) are continuous is shown. Here, the bag bodies (pl, p2, p3, p4,..., pn) are placed on the conveyor 65 located on the downstream side of the bag making machine (not shown) one by one. The bag bodies, such as the bag bodies p4, p5, p6, p7, on the conveyor 65 are sequentially placed on the one base material 25b.

[0162] (Step 4)

[0163] Preferably, multiple bag bodies 23 are moved along the length direction Y while being placed on a substrate 25b, simultaneously covering another substrate 25a moving along the length direction Y. The interlocking members 24a and 24b are engaged by the claw-like abutment 67. The product storage outer bag 300 is obtained through the engagement of the interlocking members 24a and 24b. When the product storage outer bag 300 with the interlocking members 24a and 24b engaged passes through the pinch rollers 62b and 62c, the interior of the product storage outer bag 300 is degassed, thereby reducing its volume. The bag bodies 23 can be placed into the cylindrical outer bag 21 by simply dividing the cylindrical outer bag 21 with interlocking members into one substrate 25b and another substrate 25a, placing the bag bodies 23 between them, and then sealing it as is.

[0164] (Step 5)

[0165] The outer product storage bag 300 is rolled onto the roller 51 in a flat cross-section to obtain the rolled product 57 of the outer product storage bag. Figure 18 The text indicates a rolled-up form, but the product can also be stored in an outer bag 300 with its cross-section flattened by twisting or folding.

[0166] Next, refer to Figure 19 This invention describes a method for manufacturing rolled-up product storage outer bags using the product storage outer bag of this embodiment, wherein the outer bag is a type of cylindrical outer bag without fittings. The product storage outer bag manufacturing method of this embodiment involves wrapping multiple bag bodies 33 with an outer packaging cylindrical outer bag 31 and maintaining the bag bodies 33 in a stacked state to create an integrated product storage outer bag. The multiple bag bodies 33 are stacked continuously or intermittently in a row, overlapping as part of the bag bodies (p1, p2, p3, p4, ..., pn) that are products. The manufacturing method includes: step A, preparing a resin film of equal width as a substrate 35; step B, unfolding the substrate 35; and step C, placing the multiple bag bodies along the length Y direction of the substrate 35. In step D, the substrate 35 is continuously or intermittently stacked on the substrate 35 in such a way that a portion of the bag bodies (p1, p2, p3, p4, ..., pn) overlaps; while moving the substrate 35, which carries a plurality of bag bodies 33, along the length direction Y of the substrate 35, the substrate 35 is folded to wrap the plurality of bag bodies 33, and the inner walls 38a, 38b of the substrate 35 or the inner wall 38a and the outer wall 38d are bonded or heat-fused along the edges 35a, 35b at both ends of the width direction of the substrate 35, thereby forming the substrate 35 into a cylindrical shape to obtain the product storage outer bag 400.

[0167] (Fourth Manufacturing Method)

[0168] (Process A)

[0169] Continue to refer to Figure 19The fourth manufacturing method will be described in more detail. A resin film in the form of a band of uniform width is prepared as the base material 35. Figure 19 A coiled product 58 of a tubular outer bag 31 is prepared, which is a tubular resin film manufactured by blow molding, and which is formed in a tubular shape continuously extending at a uniform inner diameter along the length direction of the tube. Figure 19

[0170] (Step B)

[0171] The base material 35 is brought into an unfolded state. The resin film in the form of a band of uniform width is obtained by forming a slit in a portion of the main body portion along the length direction of the tube. That is, the tubular outer bag 31 passing through the guide roller 74 is formed with a slit in a portion of the main body portion along the length direction of the tube by the cutter 72, and the base material 35 is brought into a horizontal unfolded state by the guide roller 73, and is fed to the pinch roller 62b in a state where the overlapped portions of the base material 35 are removed. Alternatively, in Step A, a coiled product obtained by winding the resin film in the form of a band of uniform width after cutting on a spool is prepared, and in Step B, the cutter can not be used, but the base material 35 can be directly fed to the pinch roller 62b in a horizontal unfolded state.

[0172] (Step C)

[0173] The base material 35 is brought into a flat sheet shape to place the bag bodies (pl, p2, p3, p4,..., pn). Specifically, a plurality of bag bodies are continuously or intermittently stacked in a row on the unfolded base material 35 in a manner that a portion of the bag bodies (pl, p2, p3, p4,..., pn) overlap along the length direction Y of the base material 35. Figure 19 In this embodiment, a state where the bag bodies are stacked in a row in a manner that the bag bodies (pl, p2, p3, p4,..., pn) are continuous is shown. Here, the bag bodies (pl, p2, p3, p4,..., pn) are placed on the conveyor 65 located on the downstream side of the bag making machine (not shown) by being conveyed one by one. The bag bodies, for example, the bag bodies p4, p5, p6, and p7 on the conveyor 65 are sequentially placed on the base material 35.

[0174] (Step D)

[0175] ​While moving the base material 35 on which the plurality of bag bodies 33 are placed in the length direction Y of the base material 35, the plurality of bag bodies 33 are wrapped with the base material 35 by the claw guide roller 63b, and the inner walls of the base material 35 are adhered or heat-fused to each other 38a, 38b along the edges 35a, 35b at both ends in the width direction of the base material 35 by the heat sealer 69 to form the joint 39, and the base material 35 is shaped into a tubular shape to obtain the product storage outer bag 400. Here, it is preferable to adhere or heat-fuse the edges at both ends in the width direction of the base material 35 above the stacked surface of the bag bodies 33. The bag bodies 33 can be easily wrapped with the outer bag in a form of a palm-joined fit, and in addition, the adhesion or heat-fusion can be easily performed. Therefore, it is easy to manufacture with a simple configuration. In the product storage outer bag 400, the plurality of bag bodies 33 are in a state of being wrapped with the outer packaging tubular outer bag 31. The heat-sealed product storage outer bag 400 is preferably sent to the contact roller 64, the pinch roller 62c, and the dancer roller 61b. At this time, it is transported in a state of lying on the joint 39. The inside of the product storage outer bag 400 is degassed, and thus the volume is reduced. Figure 19 In the above, the form in which the inner walls of the base material 35 are adhered or heat-fused to each other 38a, 38b is described, but the form in which the inner wall 38a and the outer wall 38d are adhered or heat-fused, or the form in which the inner wall 38b and the outer wall 38c are adhered or heat-fused can also be provided. Figure 19 In the above, the form in which heat sealing is performed by the heat sealer 69 is described, but the adhesion can also be performed using a paste. In the process A, in either of the form in which the take-up product 58 of the tubular outer bag 31 is used, and the form in which the cut-off equal-width band-shaped resin film is wound on the spool to obtain a take-up product, after the joint 39 is formed, a state in which the plurality of bag bodies 33 are wrapped with the outer packaging tubular outer bag 31 can be obtained.

[0176] (5th Process)

[0177] The product storage outer bag 400 is taken up on the spool 51 in a state of a flattened cross section to obtain a product storage outer bag take-up product 70. Figure 19 In the above, the form in which the product storage outer bag 400 is wound into a tube is described, but the product storage outer bag 400 can also be twisted or folded in a state of a flattened cross section.

[0178] (5th Manufacturing Method)

[0179] Next, the 5th manufacturing method will be described. The 5th manufacturing method is the same as the 2nd manufacturing method except that, instead of engaging the fitting member to obtain the product storage outer bag, the base material is adhered or heat-fused to obtain the product storage outer bag. That is, in the process A, one base material is prepared, in the process B, the base material is spread in a U-shaped or V-shaped form in the cross section in the length direction of the base material, and in the process C, the bag body is placed inside the U-shaped or V-shaped base material in a state in which either of the left and right side ends of the bag body faces downward. Figure 19In the present embodiment, the horizontally flatly spread form is shown as the form of the base material 35 after being spread, but it can also be configured as Figure 17 The form shown in FIG. 6, that is, the form in which the base material is in a U-shaped or V-shaped cross section, and the pouches 33 are stacked in a vertical state with the side ends abutting against the base material. In this form, the joint portion of the base material is located at the side end side of the pouches 33.

[0180] (Sixth manufacturing method)

[0181] Next, the sixth manufacturing method will be described. The sixth manufacturing method is the same as the third manufacturing method except that, instead of obtaining the product storage outer bag by engaging the fitting members, the product storage outer bag is obtained by bonding or heat welding the base materials. That is, in Step A, two base materials are prepared, in Step B, one base material is spread horizontally, and the other base material is spread horizontally above the one base material, in Step C, the one base material is made into a flat sheet with the width direction both ends of the one base material located at the left side end side and the right side end side of the pouches, and the pouches are placed on the one base material, and in Step D, the other base material is made to cover the pouches, and the one base material and the other base material are joined. The pouches can be put into the outer bag by simply arranging the two base materials one above the other, arranging the pouches therebetween, and closing them. In this form, the joint portion of the base material is located at the side end side of both sides of the pouches 33.

[0182] (Pouch supply method)

[0183] Referring to Figure 20 The pouch supply method of the present embodiment will be described. The pouch supply method of the present embodiment has: a sixth step of opening the outer bag of the product storage outer bag 100 of the present embodiment or the wound product 50 of the product storage outer bag of the present embodiment while drawing out the outer bag; and a seventh step of sequentially supplying the pouches 3 in the outer bag that has been opened to a filling machine. The product storage outer bags 200, 300, 400 can also be used as the product storage outer bag. Further, the wound product 54, 57, 70 of the product storage outer bag can also be used as the wound product of the product storage outer bag. In the case of using the product storage outer bag 400 or the wound product 70 of the product storage outer bag, the joint portion or the portion other than the joint portion in the outer bag is opened while the outer bag is drawn out. Furthermore, the folded product of the product storage outer bag can also be used. In the case of opening the portion other than the engaging portion in the outer bag, the joint portion, or the portion other than the joint portion in the outer bag, it is preferable to use a cutter to open it. Further, in the case where the portion other than the engaging portion in the outer bag, the joint portion, or the portion other than the joint portion in the outer bag is provided with a weak portion, it can also be opened from the weak portion.

[0184] (Sixth step)

[0185] As Figure 20As shown, a process opposite to the outer bag manufacturing process of the article storage outer bag 100 or the article storage outer bag's wound product 50 is performed. That is, the article storage outer bag's wound product 50 is sent to the dancer roll 80, the pinch roll 81, the contact roll 82, and then the horizontal fitting member 4 is made to stand up by the guide roll 83. Then, the claw guide roll 84 guides the female member 4b and the male member 4a, respectively, and the fitting member 4 is opened at the engaged portion or at a portion other than the engaged portion in the outer bag. In addition, in the case of using the article storage outer bag 400 or the article storage outer bag's wound product 70, the outer bag is extracted while the joint portion or a portion other than the joint portion in the outer bag is opened. In the sixth process, the state in which the bag body 3 has been loaded into the bag 1 can be directly reproduced. In addition, the outer bag 1 is sent to the pinch roll 87, the contact roll 93, and further wound by the winding shaft 91 to produce the outer bag 1's wound product 90. The outer bag 1 wound into the outer bag 1's wound product 90 is discarded after use.

[0186] (Seventh Process)

[0187] The bag body 3 in the opened outer bag 1 is sequentially supplied to the filling machine. Here, the leading bag body p4 in the bag body 3 placed on the base material 5 is detected by the bag detection tool 86, the leading bag body p4 is taken out by the suction tool 85, and placed on one end side of the positioning device 92 to become the bag body p3. The bag body p3 placed on one end side of the positioning device 92 is moved to the other end side of the positioning device 92 by the suction tool 88 to become the bag body p2. Whether or not the bag body is present at the position of the bag body p2 is detected by the bag detection tool 89. Then, the bag body p2 is supplied to the filling machine (not shown) as the bag body p1.

[0188] In the sixth process and the seventh process, the article storage outer bag 100 or the article storage outer bag's wound product 50 can substantially reproduce the bag making machine, and the bag body 3 can be supplied to the filling machine at high speed. That is, it can be said that the production line of the bag making machine can be substantially reproduced in the filling machine. Furthermore, it can be seen that the bag bundle work is not required, and in addition, the quality inspection process accompanying the bundle work is not required.

[0189] The present embodiment has multiple forms, and variations can be implemented by appropriately replacing a part of each embodiment within a range in which the effects of the present application are exerted.

[0190] In the present embodiment, a form in which the article storage outer bag is made by wrapping a plurality of bag bodies with a cylindrical outer bag with a fitting member is described, but the article is not limited to Figure 8 and Figure 9The bag body shown, for example, can also be applied to a product in the shape of a card. The product is preferably a product stacked in a column in a partially overlapping manner, and can also be a paper product such as an advertisement, a brochure, or a booklet, a sheet-shaped desiccant, a pet pad, or a sheet-shaped food material such as a snack or nori. In addition, it is also possible to wrap the product with the bag body using the tubular outer bag with the fitting member or the tubular outer bag in a manner such that the product not having the shape of a card is arranged in a column at equal intervals and is held in this state.
