Description

[Technical Field]

[0001] The present invention relates to a bi-fold paper wallet constructed by folding, gluing and sewing together paper material. [Background technology]

[0002] As disclosed in Patent Documents 1 and 2, conventional wallets have the inside of the wallet body divided into multiple sections by partitions, and are provided with a bill compartment, a coin compartment, and a card compartment. The wallet body is provided with a zipper or male and female hooks, allowing the wallet body to be opened or closed. The wallet body is generally made of animal leather or synthetic leather, and in some wallets, only the card compartment is made of a synthetic resin film. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3244833 [Patent Document 2] Japanese Patent Application Publication No. 2023-101628 Summary of the Invention [Problem to be solved by the invention]

[0004] <Size Issues> In recent years, the frequency of cashless payments, which involve making payments using methods other than cash, has increased, while cash payments have been declining year by year. As a result, there is no longer a need to carry a lot of cash in a wallet, and people are using wallets less frequently in their daily lives. Therefore, the inventors decided to create a lightweight, compact wallet with the minimum necessary functions that would not take up much space when carried in a bag or pocket.

[0005] <Material Issues> Typical wallets are made from animal leather, including cow, horse, pig, crocodile, snake, and lizard. Sacrificing animal life for human consumption violates modern moral and ethical standards. Furthermore, the process of manufacturing leather products uses a large amount of water and chemicals. The large amount of water consumed leads to large amounts of energy consumption and produces a lot of carbon dioxide. Meanwhile, chemicals include surfactants, acids, disinfectants, and bleaches. For example, in areas with a thriving leather industry, such as Hebei Province in the People's Republic of China, river pollution is a problem. To reduce the burden on animals and the environment, it is desirable to eliminate the use of animal leather (animal-free) in the future.

[0006] Synthetic leather (fake leather) has become widely used as an alternative to animal leather for wallets. Synthetic leather is made by coating a base material such as cloth with synthetic resins, such as polyurethane or polyvinyl chloride, and has a texture similar to that of animal leather. However, the synthetic resin that makes up synthetic leather is primarily made from naphtha (crude gasoline) obtained during the petroleum refining process. As a result, CO2 is emitted during the synthetic resin manufacturing process, the incineration of discarded synthetic resin, and the recycling of discarded synthetic resin. Furthermore, discarded synthetic resin does not decompose naturally and remains on land and in the ocean, adversely affecting the global environment.

[0007] <Design Issues> The surface of a conventional wallet is designed using the texture of the material itself, the color applied to the material, or the pattern printed on the material. As a result, conventional wallets only offer a few different colors or patterns, resulting in limited design freedom. For example, it was not possible to design the surface of a wallet in any color or pattern according to a customer's order, as this would have involved significant manufacturing costs.

[0008] <Objective of the present invention> The bi-fold paper wallet of the present invention has been made in consideration of the above problems, and aims to solve the following problems a) to c). a) To provide a lightweight and compact wallet with the minimum necessary functions. b) It is environmentally friendly as it does not use any animal or synthetic leather. c) It allows for a high degree of freedom in design, making it possible to produce products designed to customer orders at low cost in small quantities. [Means for solving the problem]

[0009] (1) In order to achieve the above object, the bi-fold paper wallet of the present invention is a bi-fold paper wallet constructed by folding, gluing, and sewing together a substantially rectangular paper material, at least the surface of which is decorated by printing, and includes a bag-shaped wallet body with openings on both the left and right ends, formed by folding the center of the short side of the paper material along the long side of the paper material so that the decorated surface faces outward, and a card holder formed by folding the left side or right side of the wallet body inward along the short side of the wallet body. The wallet comprises an insert section, a coin purse section formed by folding the right or left side section of the wallet body inward along the short side of the wallet body, a lid formed by folding one open end of the coin purse section toward the coin purse section, and a bill compartment section formed between the wallet body, the card slot section and the coin purse section by sewing together the vicinity of the bottom edge of each of the card slot section and the coin purse section with the vicinity of the bottom edge of the wallet body, and the center of the longitudinal direction of the wallet body that forms the bill compartment is folded along the short side of the wallet body.

[0010] (2) Preferably, in the bi-fold paper wallet of (1) above, adhesive margins are provided on each of the two short sides of the paper material, and each of the two adhesive margins is folded toward the back side of the paper material, and the adhesive margins and the paper material are sewn together near each of the two folds parallel to the folds.

[0011] (3) Preferably, in the bi-fold paper wallet of (1) above, the folds that define the boundaries between the card holder section and the wallet body, and the folds that define the boundaries between the coin purse section and the wallet body, are sewn together along the respective folds.

[0012] (4) Preferably, in the bi-fold paper wallet of (1) above, the paper material is made of PAPTIC (registered trademark) or TYVEK (registered trademark).

[0013] (5) Preferably, the bi-fold paper wallet of any one of (1) to (4) above further comprises a round tack, a rivet, and a string, the rivet fastening the round tack to the surface of the wallet body and fastening one end of the string, the string having a length that can make at least one full circle around the outside of the wallet body when folded in half, and the other end of the string that has made one full circle around the outside of the wallet body can be sandwiched between the round tack and the surface of the wallet body. [Effects of the Invention]

[0014] The bi-fold paper wallet of the present invention is made by folding, gluing, and sewing together a roughly rectangular paper material, at least the surface of which has been decorated by printing, to form the wallet body, card slots, coin purse with a lid, and bill compartment. This bi-fold paper wallet of the present invention has the minimum necessary functions, and the entire wallet can be made thin and small, making it extremely light and compact. Furthermore, the bi-fold paper wallet of the present invention does not use any animal leather or synthetic leather, making it environmentally friendly.

DETAILED DESCRIPTION OF THE INVENTION

[0016] 1. Composition of a bi-fold wallet First, the configuration of a bi-fold wallet according to an embodiment of the present invention will be described with reference to Fig. 1. Figs. 1(a) to 1(e) show a bi-fold wallet 1 of this embodiment. As shown in Fig. 1(e), the bi-fold wallet 1 is composed of a wallet main body 10, a card slot section 11, a coin purse section 12, and a bill compartment section 13. The coin purse section 12 has a lid 12a. As shown in Figs. 1(a) and 1(c), a round tuck 21 and a string 23 are attached to the front of the wallet main body 10 with rivets 22. The gray coloring in Figs. 1(a) to 1(e) represents decoration printed on the surface of the paper material 100 (see Fig. 2(a)) that constitutes the bi-fold wallet 1. The decoration will be described in detail later.

[0017] In FIG. 1(e), the wallet main body 10, card holder section 11, coin purse section 12, and lid 12a are all bag-shaped, made by doubling up a paper material 100. As shown in FIG. 6(c), fold 101G, which marks the boundary between the wallet main body 10 and the card holder section 11, is sewn together with a straight stitch 104A. Similarly, fold 101I, which marks the boundary between the wallet main body 10 and the coin purse section 12, is sewn together with a straight stitch 104A. This cuts off communication between the card holder section 11 and the coin purse section 12 and the wallet main body 10. The card holder section 11 can hold multiple cards, such as business cards and cash cards. The coin purse section 12 can hold multiple coins. The lid 12a is bent toward the coin purse part 12, the wallet body 10 is folded in half, and the closed state of the wallet body 10 is maintained by the round tuck 21 and the string 23, so that the coins stored in the coin purse part 12 will not come out of the coin purse part 12.

[0018] As shown in Figure 1(e), the vicinity of the bottom edge of each of the card holder section 11 and the coin purse section 12 is sewn to the vicinity of the bottom edge of the wallet main body 10 by a backstitch 104B. This forms a bill compartment 13 between the wallet main body 10, the card holder section 11, and the coin purse section 12. The bill compartment 13 can hold multiple bills. The left and right sides of a bill stored in the bill compartment 13 are sandwiched between the card holder section 11 and the coin purse section 12, respectively, and the wallet main body 10.

[0019] The rivet 22 shown in FIGS. 1(a) and 1(c) secures the round tuck 21 to the surface of the wallet body 10 and also secures one end of the string 23. The string 23 is long enough to wrap around the outside of the wallet body 10 at least once. The other end of the string 23 that has wrapped around the outside of the wallet body 10 can be sandwiched between the round tuck 21 and the surface of the wallet body 10. The round tuck 21 can be made of PASCO (registered trademark), a product of Hokuetsu Corporation. PASCO (registered trademark) is an environmentally friendly special hard fiberboard made primarily from wood fibers such as recycled paper and fresh pulp.

[0020] 2. Manufacturing method of bi-fold paper wallet Next, a method for manufacturing the bi-fold paper wallet 1 according to this embodiment will be described with reference to FIGS.

[0021] 2.1 Paper material 2(a) and (b) show a sheet of paper material 100 that makes up the bi-fold paper wallet 1. The paper material 100 has a roughly rectangular outline with long left and right sides and short top and bottom sides. In the description of this embodiment, the direction in which the left and right sides of the paper material 100 extend is referred to as the "longitudinal direction," and the direction in which the top and bottom sides extend is referred to as the "transverse direction."

[0022] The paper material 100 is made of paper or a material similar to paper that has flexible flexibility, strength so that it does not easily tear, and water resistance so that water does not soak in. For the paper material 100, it is preferable to use, for example, a product name "PAPTIC (registered trademark)" sold by Itochu Corporation or a product name "TYVEK (registered trademark)" sold by DuPont Safety and Construction, Inc.

[0023] PAPTIC® is made primarily from pulp derived from sustainable forests and combines high flexibility with strength. TYVEK®, on the other hand, is a web (fiber group) formed by instantly transferring high-density polyethylene polymer from a high-temperature, high-pressure state to a room-temperature, normal-pressure state. The average fiber diameter is 4 μm, and fine long fibers and thick long fibers are randomly intersected and layered. The long fibers are bonded together using heat and pressure without the use of a binder.

[0024] As already mentioned, the surface of the paper material 100 shown in FIG. 2(a) is decorated by printing. The gray coloring in the figure represents the decoration printed on the surface of the paper material 100. The decoration is applied to the surface of the paper material 100 by, for example, screen printing, digital printing, or offset printing. Furthermore, the surface of the paper material 100 can be textured, such as embossed, or stamped with gold or silver foil. By combining printing, textured, and foil stamping, the appearance and texture of the bi-fold paper wallet 1 can be freely designed.

[0025] The surface of the paper material 100 shown in Figure 2(a) has six folds 101A, 101B, 101G, 101H, 101I, and 101J extending in the short direction and four folds 101C, 101D, 101E, and 101F extending in the long direction. Furthermore, in the paper material 100 shown in Figure 2(a), adhesive margins 102A, 102B, and 102E are provided above fold 101A, below fold 101B, and to the right of fold 101E, respectively. Furthermore, small adhesive margins 102C and 102D are provided to the left of short fold 101C and to the left of short fold 101D, respectively.

[0026] In the region between the two folds 101G and 101J extending in the short direction, two punched holes 103A and 103B are formed at positions symmetrical to each other with respect to the fold 101F extending in the longitudinal direction. The rivet 22 shown in Figures 1(a) and 1(c) is inserted through the overlapping punched holes 103A and 103B and crimped while passing through the wallet body 10.

[0027] 2.2 Manufacturing method Next, a method for manufacturing the bi-fold paper wallet 1 of this embodiment will be described. Note that the procedure for manufacturing the bi-fold paper wallet 1 described below is an example and is not particularly limited.

[0028] 3(a), with the backside of the paper material 100 facing up, double-sided tape 105 is attached to the backside of each of the upper and lower adhesive margins 102A and 102B. Next, each of the upper and lower adhesive margins 102A and 102B is folded along two folds 101A and 101B toward the backside of the paper material 100, and attached to the backside of the paper material 100.

[0029] As shown in Figure 3(b), the paper material 100 is placed with its front side facing up. By attaching the upper and lower adhesive margins 102A and 102B to the back side of the paper material 100, the fold 101A becomes the top edge of the paper material 100, and the fold 101B becomes the bottom edge of the paper material 100. The part of the top edge 0.5 mm below the fold 101A is sewn together with a straight stitch 104A parallel to the fold 101A. Similarly, the part of the bottom edge 0.5 mm above the fold 101B is sewn together with a straight stitch 104A parallel to the fold 101B.

[0030] As shown in Figure 4(a), double-sided tape 105 is applied to the front side of right-side adhesive margin 102E. Next, as shown in Figure 4(b), with the backside of the paper material 100 facing up, double-sided tape 105 is applied to the backside of each of the upper right and lower right adhesive margins 102C and 102D in the figure. Next, as shown in the enlarged view in Figure 4(b), each of the upper right and lower right adhesive margins 102C and 102D is folded toward the backside of the paper material 100 along the two folds 101C and 101D, and is attached to one end of each of the adhesive margins 102A and 102B.

[0031] As shown in FIG. 5(a), with the paper material 100 facing up, the adhesive margin 102E on the right side in the figure is folded along the fold line 101E extending in the longitudinal direction toward the back side of the paper material 100. As a result, the paper material 100 shown in FIG. 5(a) becomes symmetrical with respect to the fold line 101F extending in the longitudinal direction. The part of the paper material 100 to the left of the fold line 101F will form the inner surface of the bifold paper wallet 1. Meanwhile, the part of the paper material 100 to the right of the fold line 101F will form the outer surface of the bifold paper wallet 1.

[0032] As shown in FIG. 5(b), the center of the short side of the paper material 100 is folded along a fold 101F extending in the longitudinal direction. Next, the two long sides of the paper material 100 are attached together using double-sided tape 105 with adhesive margins 102E. The attachment should be performed in the order shown by (1) to (5) in FIG. 5(b). That is, the upper ends (1) of the two long sides of the paper material 100 are attached together, followed by the lower ends (2). Next, the portion (3) above the lower ends (2) is attached, followed by the center (4). Then, the portion (5) below the upper end (1) is attached. At this time, as shown in FIG. 5(c), the long side of the portion of the paper material 100 that constitutes the inner surface is attached to the double-sided tape 105 so that it is approximately 0.1 mm lower than the long side (fold 101E) of the portion that constitutes the outer surface. This results in the formation of a longitudinally extending gap 106 as shown in the enlarged view of FIG. 5(c).

[0033] Figure 6(a) shows the outer surface of the paper material 100 folded along the fold line 101F, while Figure 6(b) shows the inner surface of the paper material 100 folded along the fold line 101F. The paper material 100 shown in Figures 6(a) and (b) is bag-shaped with openings on both the left and right ends.

[0034] The four sides of the paper material 100 shown in Figures 6(a) and (b) are formed with strong folds 101A, 101B, 101E, and 101F. This prevents the edges of the sheet of paper material 100 shown in Figures 2(a) and (b) from fraying due to friction. The presence or absence of misalignment 106 shown in Figure 6(b) is a structural feature that distinguishes the outer and inner surfaces of the paper material 100 in the manufacturing process shown in Figure 6(c) and subsequent steps.

[0035] As shown in Figure 6(c), the outer surface of the paper material 100 is placed facing up. With fold line 101J in Figure 6(c) as the center, fold line 101G on the right side is sewn together with straight stitch 104A. Fold line 101G is the boundary between the card slot section 11 and the wallet body 10. By sewing fold line 101G together with straight stitch 104A, the communication between the card slot section 11 and the wallet body 10 is severed.

[0036] As above, with fold 101J in Figure 6(c) as the center, fold 101I on the left side is sewn together with straight stitch 104A. Fold 101I is the boundary between coin purse section 12 and wallet body 10. By sewing fold 101I together with straight stitch 104A, the communication between coin purse section 12 and wallet body 10 is severed.

[0037] As shown in Figure 6(c), the card holder section 11 of the paper material 100 is folded along the right fold 101G toward the inner surface of the paper material 100. Next, as shown in Figure 6(d), the vicinity of the bottom edge of the card holder section 11 folded toward the inner surface is sewn together with a backstitch 104B from the outer surface side of the paper material 100. It is preferable that this backstitch 104B be located 0.4 mm above the bottom edge of the paper material 100 shown in Figure 6(d).

[0038] As shown in FIG. 7(a), the inner surface of the paper material 100 is placed facing up. The coin purse section 12 of the paper material 100 is folded toward the inner surface of the paper material 100 along the right-side fold 101I, centered on the fold 101J in FIG. 7(a). Next, as shown in FIG. 7(b), the vicinity of the bottom edge of the coin purse section 12 folded toward the inner surface is sewn together from the inner surface side of the paper material 100 with a main backstitch 104B. It is preferable that this main backstitch 104B be positioned 0.4 mm above the bottom edge of the paper material 100 shown in FIG. 7(b). At this time, the lid 12a of the coin purse section 12 is not sewn to the inner surface of the paper material 100.

[0039] As shown in FIG. 7(b), the lid 12a of the coin purse section 12 is folded toward the coin purse section 12 (the side opposite the inner surface of the paper material 100) along the fold line 101H in the short direction. This completes the coin purse section 12 equipped with the lid 12a, as shown in FIG. 7(c). Next, the wallet body 10 is folded along the fold line 101J in the center of the wallet body 10 in the longitudinal direction. Finally, rivets 22 are inserted into the punched holes 103A and 103B of the wallet body 10 and tightened to secure the round tuck 21 and string 23 to the wallet body 10. Through the above manufacturing steps, the bifold wallet 1 shown in FIGS. 1(a) to 1(e) is completed.

[0040] 3. Effects of bifold wallets The bifold wallet 1 of this embodiment is made by folding, gluing, and sewing together a generally rectangular paper material 100, at least the surface of which is decorated by printing, to form the wallet body 10, card slots 11, coin purse section 12 with lid 12a, and bill compartment 13. The bifold wallet 1 of this embodiment has the minimum necessary functions, allowing the entire wallet to be thin and small, making it extremely light and compact. Furthermore, the bifold wallet 1 of this embodiment does not use any animal leather or synthetic leather, making it environmentally friendly. Furthermore, the surface of the paper material 100 that constitutes the bifold wallet 1 of this embodiment can be decorated with any design by printing. This allows for a high degree of design freedom, and products designed to meet customer orders can be produced in small quantities at low cost. [Explanation of symbols]
