Abstract
Description
[Technical Field]
[0001] This invention relates to bags used when selling products. [Background technology]
[0002] Perforated bags are described in Patent Documents 1 and 2. For example, Patent Document 1 describes a zippered vinyl bag with perforations offset by 2 to 4 mm in the center of the front and back surfaces.
[0003] Patent Document 2 also describes a plastic bag for food waste fermentation, etc., which has a hanging string (1) attached to one end of the opening, a rail-type zipper (2) that can be opened and closed freely attached to the entire opening, one end (4) of the storage section cut off, and the middle part near the center is baked and glued (3) in a roughly perforated pattern.
[0004] In retail stores, products are often sold in perforated bags. For example, plastic shopping bags (plastic bags) used for shopping are sold in packs of 100, and these bags have perforations.
[0005] 7 and 8 are explanatory diagrams showing examples of bags in which general plastic bags are packaged. Fig. 7 shows the bag 800 as seen from the front side. Fig. 8 shows the bag 800 as seen from the back side.
[0006] 7 and 8, the bag 800 is used to package 100 plastic bags 900, which are products. The material of the bag 800 is, for example, polyethylene. When the material of the bag 800 is polyethylene, the front and back surfaces of the bag 800 are, for example, film.
[0007] 7 and 8 is transparent, for example. An upper side 810 and a bottom side 820 of the bag 800 are sealed.
[0008] 7 and 8, bag 800 has perforation 830 between top side 810 and bottom side 820, running around the front surface and the back surface of bag 800. After purchasing bag 800, a customer divides bag 800 along perforation 830.
[0009] 7 and 8, bag 800 has hole 840. Hole 840 is positioned so as to overlap with a hole in plastic bag 900. Therefore, a store clerk can sell bag 800 by hanging hole 840 on a hook or the like. Note that hole 840 does not have to be positioned so as to overlap with a hole in plastic bag 900.
[0010] Furthermore, on the surface of the bag 800, product information 850 is printed, as shown in FIG.
[0011] Figure 9 is an explanatory diagram showing another example of a bag containing a typical plastic bag. Figure 9 shows bag 800A as seen from the front after it has been divided along perforation 830. Customers use plastic bag 900 by removing it from the direction indicated by the black arrow in Figure 9. [Prior art documents] [Patent documents]
[0012] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-47907 [Patent Document 2] Japanese Patent Application Publication No. 08-324702 Summary of the Invention [Problem to be solved by the invention]
[0013] 9, product information 850 remains on the surface of bag 800A even after bag 800 is divided along perforation 830. Product information 850 is useful information when a customer purchases bag 800.
[0014] However, when a customer purchases bag 800 and hangs bag 800A, which has been divided by perforation 830, on a hook indoors or elsewhere, product information 850 may become a nuisance to the customer. Reasons for this being the case include the information no longer being needed, or the use of color being an eyesore, etc.
[0015] Patent Documents 1 and 2 do not describe a bag that can solve the above problems.
[0016] Therefore, the present invention aims to provide a bag that is less cumbersome for customers to use after purchase. [Means for solving the problem]
[0017] The bag of this invention is a bag for packaging goods, and has a perforation that runs around the entire front and back surfaces of the bag between the sealed top and bottom edges of the bag, and product information is written only in the area between the bottom edge of the front surface and the perforation, or the area between the bottom edge of the back surface and the perforation. [Effects of the Invention]
[0018] The present invention provides a bag that is less cumbersome for customers to use after purchase. [Brief explanation of the drawings]

[0020] [Configuration Description] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each drawing, the same or corresponding parts are designated by the same reference numerals, and their description will be omitted or simplified as appropriate. Furthermore, the shape, size, and arrangement of the components shown in each drawing may be changed as appropriate within the scope of the present invention.
[0021] Figures 1 and 2 are explanatory diagrams showing an example of a bag according to an embodiment of the present invention. Figure 1 shows the bag 100 as seen from the front side. Figure 2 shows the bag 100 as seen from the back side. The bag 100 shown in Figures 1 and 2 is used to package 100 plastic bags 900, which are commercial products.
[0022] The material of the bag 100 in this embodiment is, for example, polyethylene. When the material of the bag 100 is polyethylene, the front and back surfaces constituting the bag 100 are, for example, film. The color of the bag 100 is, for example, transparent. The top edge 110 and the bottom edge 120 of the bag 100 are each sealed.
[0023] 1 and 2, the bag 100 of this embodiment has a perforation 130 that runs around the front surface and the back surface of the bag 100 between the top side 110 and the bottom side 120. After purchasing the bag 100, the customer divides the bag 100 along the perforation 130.
[0024] 1 and 2, the bag 100 of this embodiment has a hole 140. The hole 140 is positioned so as to overlap with a hole in the plastic bag 900. This allows a store clerk to sell the bag 100 by hanging the hole 140 on a hook or the like. Note that the hole 140 does not have to be positioned so as to overlap with the hole in the plastic bag 900.
[0025] 1, product information 150 is printed on the surface of bag 100 of this embodiment. Unlike product information 850 shown in FIG. 7, product information 150 of this embodiment is printed only on the surface between bottom edge 120 and perforation 130.
[0026] In this embodiment, the product information 150 may be written only on the back surface between the bottom edge 120 and the perforation 130. In addition, the product information 150 may be written only on the front surface between the bottom edge 120 and the perforation 130 and on the back surface between the bottom edge 120 and the perforation 130.
[0027] Figure 3 is an explanatory diagram showing another example of a bag according to an embodiment of the present invention. Figure 3 shows bag 100A as seen from the front side after it has been divided along perforation 130. Customers use plastic bag 900 by removing it from the direction indicated by the black arrow in Figure 3.
[0028] As shown in Figure 3, no product information 150 remains on bag 100A after it has been divided along perforation 130. Therefore, even if a customer purchases bag 100 of this embodiment and hangs bag 100A after it has been divided along perforation 130 on a hook indoors or elsewhere, the customer will feel less bothered than with bag 800A shown in Figure 9.
[0029] Next, a modified example of this embodiment will be described. Figure 4 is an explanatory view showing a modified example of the bag according to the embodiment of the present invention. Figure 4 shows bag 101 as seen from the front side.
[0030] Bag 101 shown in Fig. 4 differs from bag 100 shown in Fig. 1 in that it has pattern 160 on the surface that constitutes bag 101. Except for having pattern 160, bag 101 shown in Fig. 4 is similar to bag 100 shown in Fig. 1.
[0031] Specifically, in the bag 101 shown in Fig. 4, a pattern 160 spanning the perforation 130 is printed on the front surface of the bag 101. The pattern 160 spanning the perforation 130 may also be printed on the back surface of the bag 101. The pattern 160 spanning the perforation 130 may also be printed on both the front and back surfaces of the bag 101.
[0032] Figure 5 is an explanatory diagram showing another modified example of the bag according to the embodiment of the present invention. Figure 5 shows bag 101A as seen from the front side after it has been divided along perforation 130. Customers remove and use plastic bag 900 from the direction indicated by the black arrow in Figure 5. As shown in Figure 5, after it has been divided along perforation 130, the upper half of pattern 160A remains on bag 101A.
[0033] Figure 6 is an explanatory diagram showing another variation of the bag according to the embodiment of the present invention. Figure 6 shows bag 101B, seen from the front side, on which product information 150 is printed, after it has been divided along perforation 130. As shown in Figure 6, after it has been divided along perforation 130, bag 101B still has pattern 160B, which is the lower half of the bag.
[0034] One advantage of bag 101 of this modified example is that a child carrying bag 101B shown in Fig. 6 can easily find bag 101 for a purchase at a retail store. Even if a parent specifies bag 101 for a purchase, the child often cannot clearly recognize bag 101 for the purchase.
[0035] However, if a child brings bag 101B shown in Fig. 6, the child can match pattern 160B on the bottom half of bag 101B shown in Fig. 6 with pattern 160 printed on bag 101 sold at a retail store and shown in Fig. 4. By matching the two, it is thought that the child is more likely to be able to clearly recognize bag 101 that is the subject of purchase.
[0036] As described above, bag 100 of this embodiment is a bag for packaging products, and has perforation 130 that runs around the front and back surfaces of bag 100 between sealed top edge 110 and sealed bottom edge 120 of bag 100. Product information 150 is written only in the area between bottom edge 120 on the front surface and perforation 130, or in the area between bottom edge 120 and perforation 130 on the back surface.
[0037] The product information 150 may be written only on the front surface between the bottom edge 120 and the perforation 130 and on the back surface between the bottom edge 120 and the perforation 130 .
[0038] Furthermore, a predetermined pattern (for example, pattern 160) may be printed on at least either the front or back surface across perforation 130. Furthermore, the front and back surfaces may be made of film.
[0039] The material of the bags 100-101 of this embodiment may be a material other than polyethylene, as long as the bags 100-101 can be divided by the perforations 130. For example, the material of the bags 100-101 may be paper or leather.
[0040] [Effect description] The bag 100 of this embodiment has the characteristic that when it is divided along perforation 130 to remove the packaged product, no product information 150 remains on the bag 100A after it is divided along perforation 130. Therefore, compared to bags on which product information 150 remains, customers are less likely to feel bothered when using the bag indoors after purchase.
[0041] Furthermore, the surface of bag 101, which is a variation of this embodiment, has pattern 160 printed across perforation 130. Therefore, a child who visits a retail store with bag 101B that is no longer needed after being divided along perforation 130 can easily find the same bag 101 by matching pattern 160B on the remaining lower half of bag 101B with pattern 160 printed on bags 101 sold at the retail store.
