Description

[Technical Field]

[0001] The present invention relates to a palm-seam gusset bag, and also to a method for manufacturing a sheet for a palm-seam gusset bag. [Background technology]

[0002] Patent Document 1 describes a logistics monitoring support system that assigns codes (IC tags, bar codes, two-dimensional codes) to logistics items and manages the logistics items by querying the codes (checking the logistics history). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2011-204031

[0004] At work sites that handle relatively heavy (e.g., around 25 kg) bagged goods, multiple goods are loaded onto a pallet (loading platform), and the pallet is transported using a forklift or other device, and then stored in a warehouse or other location. Because multiple goods are loaded onto a pallet, the code attached to a goods may be hidden by other goods next to it. In this case, in order to manage the goods with the hidden code (to read the code), the goods must first be unloaded from the pallet. Summary of the Invention [Problem to be solved by the invention]

[0005] The object of this invention is to expose the identification codes attached to each of the multiple distribution items, even when multiple distribution items are loaded on a pallet, so that the identification codes of each of the multiple distribution items on the pallet can be read without unloading the distribution items from the pallet.

[0006] The above-mentioned object of the present invention is achieved by the gable gusset bag provided by the present invention. The gable gusset bag has gusset sections on both the left and right sides, and becomes a rectangular parallelepiped when contents are placed inside, with top and bottom seal sections at the top and bottom ends and a back seal section at the back. The gable gusset bag can store, for example, granular materials such as chemicals, pesticides, and resins, as well as powdery materials. When no contents are placed inside the gable gusset bag, the gusset sections do not expand, making the bag compact. When contents are placed inside the bag, the gusset sections on both sides expand, forming a roughly rectangular parallelepiped shape, and the gable gusset bag has four sides (top, bottom, left, and right), a front (top surface), and a back (bottom surface, ground surface).

[0007] The gusseted bag of this invention is characterized in that a unique and identical identification code is printed on each of the four sides (top, bottom, left and right) of the rectangular shaped gusseted bag.

[0008] According to this invention, a unique and identical identification code is printed on each of the four sides (top, bottom, left, and right) of a rectangular parallelepiped gusset bag, so if any of the four sides is exposed (if it can be photographed by a camera), the identification code can be read, making it possible to confirm the logistics history, etc. In particular, when rectangular parallelepiped gusset bags are stacked in multiple layers vertically on a pallet, the identification code of a gusset bag that is not on the top layer can be read from any of the four sides (top, bottom, left, and right).

[0009] In one embodiment, the identification code is printed on the front (top) of the gusseted bag. By printing the identification code on the front of the gusseted bag as well, the identification code of the gusseted bag stacked on the top shelf of the pallet can be read from above.

[0010] Preferably, one of the identification codes on the left and right side surfaces that have the gusset portions is printed near the upper side surface, and the other is printed near the lower side surface. For example, if both of the identification codes on the left and right side surfaces are printed near the upper side surfaces of the gusseted bag, the distance between the identification codes of adjacent gusseted bags may become close when multiple gusseted bags are loaded on a pallet. By printing one of the identification codes on the left and right side surfaces near the upper side surface and the other near the lower side surface, the distance between the identification codes of adjacent gusseted bags can be increased, thereby reducing the risk of misreading the identification codes.

[0011] Preferably, one of the identification codes on the top and bottom sides that do not have the gusset is printed near the left side, and the other is printed near the right side. As with the above, the distance between the identification codes of adjacent gusseted bags can be increased, which can prevent errors in reading the identification codes.

[0012] In one embodiment, the gusseted bag is made of a laminated film made by laminating multiple types of film. Identification codes can be fixed by printing at multiple positions on the gusseted bag (positions that will become the four sides (top, bottom, left, and right) when the bag is roughly shaped like a rectangular parallelepiped).

[0013] This invention also provides a method for manufacturing a sheet for a gusseted bag as described above. The method for manufacturing a sheet for a gusseted bag according to this invention is a method for manufacturing the sheet for a gusseted bag formed from a single laminated film sheet, having gusset sections on both left and right sides, and having top and bottom seal sections on the top and bottom ends and a back seal section on the back surface, which becomes a rectangular parallelepiped when contents are placed inside, and is characterized in that a unique and identical identification code is printed on each of the sheets at positions that will become the four sides (top, bottom, left, and right) when the sheet is formed into a rectangular parallelepiped when contents are placed inside. [Brief explanation of the drawings]

[0014] [Figure 1] FIG. 2 is a front perspective view of the gusseted bag. [Figure 2] FIG. 2 is a perspective view of the gusseted bag shown in FIG. 1 as seen from the back. [Figure 3] FIG. 2 is a development view of the gusseted bag shown in FIG. [Figure 4] Shown is a stack of five gusset bags on a pallet. [Example]

[0015] Fig. 1 is a perspective view of the gusseted bag 1 as seen from the front, and Fig. 2 is a perspective view of the gusseted bag 1 as seen from the back. Fig. 3 is a development view of the gusseted bag 1 (sheet 1A for manufacturing the gusseted bag 1).

[0016] The gable gusset bag 1 is formed from a single laminated film sheet 1A. For example, a sheet laminated from the front to the back of the bag may be used, in which grip varnish / biaxially oriented nylon film (15 μm thick) / pattern ink / adhesive / aluminum (7 μm thick) / adhesive / biaxially oriented nylon film (25 μm thick) / adhesive / linear low-density polyethylene film (120 μm thick) is used. Instead of laminating grip varnish and biaxially oriented nylon film on the outermost surface, a non-slip biaxially oriented nylon film (15 μm thick) may also be laminated. Any layer configuration can be adopted depending on the contents to be stored in the gable gusset bag 1 and the desired functions (light blocking, water resistance, etc.).

[0017] The gusseted bag 1 (sheet 1A) has a rectangular front portion (top portion) 10, side portions 11, 12 continuing from the left and right ends of the front portion 10, first and second back portions (bottom portion, base portion) 13A, 13B continuing from the side portions 11, 12, respectively, and first and second back seal portions 19A, 19B continuing from the first and second back portions 13A, 13B, respectively. The left and right side portions 11 have folds 11A, 12A formed in them that extend vertically to form gusset portions. Hereinafter, the folds 11A, 12A will also be referred to as gusset portions 11A, 12A.

[0018] When no contents are stored in the gusseted bag 1, the gusset portions 11A and 12A of the gusseted bag 1 do not expand, and the gusseted bag 1 can be flattened. When contents are stored, the gusset portions 11A and 12A expand, and the gusseted bag 1 assumes a generally rectangular parallelepiped shape. Figures 1 and 2 show the gusseted bag 1 that has been converted into a rectangular parallelepiped by storing contents. When contents are stored, upper side portions 14A, 14B, and 14C are formed at the upper ends of the front portion 10 and the back portions 13A and 13B, and lower side portions 15A, 15B, and 15C are formed at the lower ends of the front portion 10 and the back portions 13A and 13B.

[0019] The gusseted sack 1 is made as follows. First, the first and second back seal portions 19A, 19B on the left and right sides of the sheet 1A are overlapped and heat-sealed to form a cylindrical body with openings at the top and bottom. With the gusset portions 11A, 12A closed (with the side portions 11, 12 folded inward along the creases 11A, 12A), the bottom end portion 18 of the sheet 1A is heat-sealed, thereby closing the bottom opening (forming the bottom seal portion 18). After the contents are placed through the top opening, the top end portion 17 of the sheet 1A is heat-sealed, and the top opening is also closed (top seal portion 17). The rectangular gusseted sack 1 with the contents placed inside is completed.

[0020] Two-dimensional codes 10a, 11a, 12a, 14a, and 15a are printed on the front portion 10, left and right side portions 11 and 12, upper side portion 14A, and lower side portion 15A of the gusseted bag 1, respectively. The two-dimensional codes 10a, 11a, 12a, 14a, and 15a are printed in advance on the sheet 1A using, for example, a thermal printer (see FIG. 3). In the case of the sheet 1A having the layer structure described above, the two-dimensional codes 10a, 11a, 12a, 14a, and 15a can be printed on the front or back of a 15 μm-thick biaxially oriented nylon film or non-slip biaxially oriented nylon film.

[0021] The five two-dimensional codes 10a, 11a, 12a, 14a, and 15a printed on a specific gusseted bag 1 (sheet 1A) are the same code (recording the same information). On the other hand, the two-dimensional codes printed on other gusseted bags 1 (sheet 1A) are different codes (recording different information). Each gusseted bag 1 (sheet 1A) is identified by the two-dimensional codes 10a, 11a, 12a, 14a, and 15a.

[0022] Two-dimensional codes 10a, 11a, 12a, 14a, and 15a represent, for example, a unique URL (uniform resource locator) for each gusseted bag 1. When one of two-dimensional codes 10a, 11a, 12a, 14a, and 15a is scanned with a two-dimensional code reader (a two-dimensional code reader application on a smartphone), the URL represented by two-dimensional code 10a, 11a, 12a, 14a, and 15a is recognized by the two-dimensional code reader. For example, by writably storing manufacturing information, arrival information, shipping information, and the like of gusseted bag 1 in a storage device identified by the address indicated by the URL, product management, inventory management, and the like at the time of arrival and shipment of gusseted bag 1 can be made more efficient.

[0023] Figure 4 shows five gusset bags 1 loaded on a pallet 20. Although Figure 4 shows five gusset bags 1 stacked in one layer, it is common for pallet 20 to have multiple layers of gusset bags 1 stacked vertically.

[0024] Two-dimensional codes 11a, 12a, 14a, 15a are printed on each of the four side surfaces of the roughly rectangular shaped gable gusset bag 1, namely, both side surfaces 11, 12, the upper side surface 14A, and the lower side surface 15A. Therefore, as long as any of the four side surfaces is exposed to the side, even if multiple gable gusset bags 1 are loaded on the pallet 20, or even if they are loaded in multiple layers, product management and inventory management can be performed for each of the gable gusset bags 1 that are still loaded on the pallet 20 by scanning any of the two-dimensional codes 11a, 12a, 14a, 15a for all of the gable gusset bags 1 loaded on the pallet 20, without having to unload them from the pallet 20.

[0025] Furthermore, since the two-dimensional code 10a is printed on the front surface 10 in addition to the four side surfaces, the two-dimensional code 10a can be scanned from above for the topmost gusseted bag 1 among the gusseted bags 1 stacked in multiple layers on the pallet 20. This is convenient when it is sufficient to scan the two-dimensional code 10a on the front surface 10 of the topmost gusseted bag 1 (for example, when a rule is established that gusseted bags 1 containing the same contents must be loaded on one pallet 20).

[0026] Of the two-dimensional codes 11a, 12a on the left and right side surface portions 11, 12, one two-dimensional code 11a is printed near the upper side surface portions 14A to 14C and the other two-dimensional code 12a is printed near the lower side surface portions 15A to 15C. Furthermore, of the two-dimensional codes 14a, 15a on the upper and lower side surface portions 14A, 15A, one two-dimensional code 14a is printed near the left side surface portion 12 and the other two-dimensional code 15a is printed near the right side surface portion 11. When multiple gusseted bags 1 are loaded on the pallet 20, the distance between the two-dimensional codes of adjacent gusseted bags 1 can be increased, which can reduce errors in reading the two-dimensional codes.
