Description

Technical Field

[0001] The present disclosure relates to a card holding sheet and a file.

Background Art

[0002] Card holding sheets for holding cards such as business cards are well known (Japanese Utility Model Laid-Open Publication No. 60-134663, Japanese Utility Model Laid-Open Publication No. 4-79683, Japanese Patent Laid-Open Publication No. 2002-347377). The card holding sheet has a plurality of slit structures. Each of the plurality of slit structures has a slit. The slit is a cut formed in the card holding sheet.

[0003] In Japanese Utility Model Laid-Open Publication No. 4-79683, each of the plurality of slit structures has one slit. When the user inserts a corner of the card into the slit, the card is held by the card holding sheet. In Japanese Patent Laid-Open Publication No. 2002-347377, each of the plurality of slit structures has a plurality of slits. When the user inserts a corner of the card into any one of the slits, the card is held by the card holding sheet.

[0004] In Japanese Utility Model Laid-Open Publication No. 60-134663, each of the plurality of slit structures has two linear slits and a clamping plate provided between the two slits. When the user lifts the clamping plate, the two slits open. After passing the corner of the card through the two slits in the state where the two slits are open, when the user releases the hand from the clamping plate, the card is held by the card holding sheet.

[0006] The card holder sheet has a front and a back. The front of the card holder sheet is the surface on which the card is placed and the surface that protects it. When a card is held on the front of the card holder sheet, it is possible to hold the card neatly while properly protecting the corners of the card.

[0007] However, in Japanese Utility Model Publication No. 4-79683 and Japanese Patent Publication No. 2002-347377, the corners of the card are inserted into the slits with the card placed on the surface of the card-holding sheet. Therefore, the corners of the card are placed on the back surface of the card-holding sheet. It is difficult to properly protect the corners of the card. Also, when inserting the corners of the card into the slits, there is a possibility that the corners of the card will hit the edges of the slits and bend.

[0008] In Japanese Utility Model Publication No. 60-134663, the corners of the card are passed through two slits, so the leading edge of the card's corners is located on the surface of the card-holding sheet. However, because the two slits are straight cuts, the two slits do not open fully unless the clamping plate is lifted significantly or the card-holding sheet is significantly bent.

[0009] Thus, conventional slit structures have the problem that it is difficult to quickly hold business cards or other cards in the card holder sheet during meetings or other breaks. There is a need for a slit structure that allows the corners of the card to be easily passed through the two slits.

[0010] This disclosure aims to solve the problems described above. [Means for solving the problem]

[0011] A first aspect of the present disclosure is a card-holding sheet comprising: a sheet having a front surface and a back surface, the front surface holding a card; and a plurality of slit structures formed by slits in the sheet, which hold the corners of the card, each of the plurality of slit structures holding one of the plurality of corners of the card; each of the plurality of slit structures comprising: a first slit located near the center of the card, which guides the corner of the card from the front surface to the back surface of the sheet; a second slit located near the corner of the card, adjacent to the first slit, which guides the corner of the card from the back surface to the front surface; and a strip-shaped retaining portion formed between the first slit and the second slit, which holds the card, wherein the first slit is curved convexly toward the center of the card, the second slit is curved convexly toward the corner of the card, and the width of both ends of the retaining portion is narrower than the width of the central part of the retaining portion.

[0012] A second aspect of this disclosure is a file comprising a card-holding sheet according to the first aspect. [Effects of the Invention]

[0013] According to this disclosure, since the first and second slits are curved convexly in opposite directions, when the user bends the sheet so that the slit structure narrows, the retaining portion curves and protrudes more significantly in the thickness direction of the sheet than the rest of the sheet. As a result, the first and second slits open sufficiently, allowing the user to easily pass the corners of a card through the first and second slits while the card is placed on the surface of the sheet. Furthermore, after passing the corners of the card through the first and second slits, when the user releases their hand from the sheet, the retaining portion presses the corners of the card in the thickness direction of the sheet. As a result, the card is held with both the center and the leading edge of the corners of the card on the surface of the sheet. Therefore, according to this disclosure, it is possible to hold the card in a clean condition while properly protecting the corners of the card. In addition, according to this disclosure, the card can be quickly held in place on the card-holding sheet.

Modes for Carrying Out the Invention

[0015] (First Embodiment) As shown in FIG. 1, a file 10A according to the first embodiment is a flat file that houses thin (sheet-like or card-like) items to be housed such as printed matter. The file 10A includes a cover body 12 and a binding tool 14.

[0016] The cover body 12 is composed of a rectangular sheet 16. The sheet 16 has flexibility. The sheet 16 is, for example, a resin sheet having translucency. The cover body 12 has a front cover 18, a back cover 20, and a back sheet 22. The cover body 12 is formed by folding the central portion of the sheet 16 in half. Note that FIG. 1 shows a state in which the cover body 12 is open.

[0017] The front cover 18 is one of the two parts sandwiching the central part of the sheet 16. The front cover 18 is the front side part of the cover body 12. The back cover 22 (sheet body) is the other of the two parts sandwiching the central part of the sheet 16. The back cover 22 is the back side part of the cover body 12. The spine 20 is the central part of the sheet 16. The spine 20 connects the front cover 18 and the back cover 22. When the cover body 12 is closed, the front cover 18 and the back cover 22 face each other. In the following description, the direction along the spine 20 will be described as the vertical direction of the file 10A.

[0018] The binding tool 14 is provided on the inner surface 12a of the cover body 12. In FIG. 1, the binding tool 14 is provided on the side of the spine 20 of the inner surface 22a of the back cover 22. The binding tool 14 binds the contained object to the inner surface 22a of the back cover 22. The first embodiment is not limited to this. By providing the binding tool 14 on the inner surface 18a of the front cover 18, the contained object may be bound to the inner surface 18a of the front cover 18.

[0019] The file 10A further includes a card holding portion 26 for holding a rectangular card 24 (see FIGS. 2 to 4) such as a business card. In the first embodiment, the card holding portion 26 is provided on the back cover 22. In the first embodiment, in the state where the file 10A is open as shown in FIG. 1, the inner surface 16a of the sheet 16, which is the inner surface 12a of the cover body 12, is referred to as the card placement surface 28. The inner surface 12a of the cover body 12 includes the inner surface 18a of the front cover 18 and the inner surface 22a of the back cover 22. Also, in the first embodiment, the outer surface 16b (see FIG. 4), which is the surface opposite to the inner surface 16a of the sheet 16, is referred to as the back surface 30.

[0020] The card holder section 26 includes a plurality of slit structures 32. The plurality of slit structures 32 are provided on the back cover 22. As shown in Figures 2 and 3, the card 24 has a plurality of corners 34. Each of the plurality of slit structures 32 holds one of the plurality of corners 34 of the card 24. Therefore, one slit structure 32 holds one corner 34. Each of the plurality of slit structures 32 holds the corner 34 of the card 24 when the card 24 is placed on the card placement surface 28. As will be described later, each of the plurality of slit structures 32 holds the corner 34 of the card 24 by sandwiching the corner 34 of the card 24.

[0021] As shown in Figure 1, in the first embodiment, three slit structures 32 (first slit structure 32a, second slit structure 32b, and third slit structure 32c) are provided on the back cover 22. The three slit structures 32 are provided on the back cover 22 with spaces between them. The three slit structures 32 are arranged on the back cover 22 in the shape of a smile.

[0022] The first slit structure 32a is located on the corner side of the back cover 22. The second slit structure 32b and the third slit structure 32c are located closer to the center of the back cover 22. The second slit structure 32b and the third slit structure 32c are spaced diagonally apart from each side of the back cover 22. The second slit structure 32b is located above the first slit structure 32a and closer to the binding mechanism 14. The third slit structure 32c is located above the first slit structure 32a and the second slit structure 32b. As shown in Figures 2 and 3, the first slit structure 32a, the second slit structure 32b, and the third slit structure 32c are each located on the diagonal of the card 24.

[0023] As shown in Figure 2, the first slit structure 32a and the second slit structure 32b are positioned diagonally to the card 24 which is arranged horizontally on the card placement surface 28. This allows the first slit structure 32a to hold one corner 34 located diagonally to the horizontally arranged card 24, and the second slit structure 32b to hold the other corner 34 located diagonally to the card 24.

[0024] As shown in Figure 3, the first slit structure 32a and the third slit structure 32c are positioned diagonally to the card 24 which is arranged vertically on the card placement surface 28. This allows the first slit structure 32a to hold one corner 34 located diagonally to the vertically arranged card 24, and the third slit structure 32c to hold the other corner 34 located diagonally to the card 24.

[0025] In the first embodiment, the configuration is not limited thereto. In the first embodiment, it is sufficient that at least two slit structures 32 are provided in the card holding portion 26. In the first embodiment, the card holding portion 26 may also be provided on the front cover 18.

[0026] As shown in Figure 1, each of the multiple slit structures 32 (first slit structure 32a, second slit structure 32b, third slit structure 32c) has a first slit 36, a second slit 38, and a retaining portion 40.

[0027] The first slit 36 ​​is a cut formed in the back cover 22. As shown in Figures 2 and 3, the first slit 36 ​​is located near the center of the card 24 when the card 24 is positioned between the first slit structure 32a and the second slit structure 32b or the third slit structure 32c on the card placement surface 28. The first slit 36 ​​is positioned diagonally with respect to each side of the back cover 22. The first slit 36 ​​is curved convexly toward the center of the card 24. As shown in Figure 4, the corners 34 of the card 24 can be inserted through the first slit 36.

[0028] As shown in Figure 1, the first slit 36 ​​has a pair of first extensions 42. The pair of first extensions 42 are notches to prevent damage to the back cover 22 by the first slit 36. As shown in Figures 2 and 3, the pair of first extensions 42 extend from both ends of the first slit 36 ​​toward the center of the card 24.

[0029] As shown in Figure 1, the second slit 38 is a cut formed in the back cover 22. As shown in Figures 2 and 3, the second slit 38 is located near the corner 34 of the card 24 when the card 24 is positioned between the two slit structures 32 on the card placement surface 28. The second slit 38 is positioned diagonally to each side of the back cover 22. The total length of the second slit 38 is shorter than the total length of the first slit 36. The second slit 38 is curved convexly toward the corner 34 of the card 24. That is, the second slit 38 is curved convexly in the opposite direction to the first slit 36. As shown in Figure 4, the corner 34 of the card 24 can pass through the second slit 38.

[0030] As shown in Figure 1, the second slit 38 has a pair of second extensions 44. The pair of second extensions 44 are notches to prevent damage to the back cover 22 by the second slit 38. As shown in Figures 2 and 3, the pair of second extensions 44 extend from both ends of the second slit 38 so as to move away from the first slit 36.

[0031] As shown in Figure 1, the retaining portion 40 is formed between the first slit 36 ​​and the second slit 38. The retaining portion 40 is a strip-shaped portion on the back cover 22 between the first slit 36 ​​and the second slit 38. As described above, the first slit 36 ​​curves convexly toward the center of the card 24, and the second slit 38 curves convexly toward the corner 34 of the card 24. Therefore, the retaining portion 40 has a shape in which the central part is wider than the side ends. Consequently, as shown in Figures 2 and 3, the width Le of the side ends of the retaining portion 40 is narrower than the width Lc of the central part of the retaining portion 40 (Le <Lc)。

[0032] As shown in Figure 4, the pressing portion 40 holds the card 24 with its corners 34 inserted through the first slit 36 ​​and the second slit 38. More specifically, with the corners 34 of the card 24 inserted through the first slit 36 ​​and the second slit 38, the pressing portion 40 presses the corners 34 of the card 24 in the thickness direction by making surface contact with the card 24.

[0033] Next, a method for holding the card 24 in the card holder 26 will be described.

[0034] First, with the file 10A open as shown in Figure 1, the user places the card 24 (see Figures 2 and 3) on the card placement surface 28. At this time, the user places the card 24 at the location on the card placement surface 28 where the three slit structures 32 are located.

[0035] Next, the user causes the first slit structure 32a to hold one corner 34 of the card 24.

[0036] Specifically, the user uses their hand to bend the back cover 22 so that the portion of the card holding section 26 with the first slit structure 32a narrows. As a result, the pressing portion 40 changes from the flat state shown in Figure 5A to the state shown in Figures 5B and 6, where the central part protrudes in the thickness direction. In other words, the pressing portion 40 protrudes more in the thickness direction than the rest of the back cover 22. As described above, the first slit 36 ​​and the second slit 38 are curved convexly in opposite directions (see Figure 1). Therefore, when the user bends the back cover 22 so that the first slit structure 32a narrows, the pressing portion 40 protrudes more in the thickness direction.

[0037] The pressing portion 40 protrudes in the thickness direction, causing the first slit 36 ​​and the second slit 38 to open. As described above, the total length of the first slit 36 ​​is longer than the total length of the second slit 38 (see Figures 2 and 3). Therefore, as shown in Figures 5B and 6, the first slit 36 ​​opens wider than the second slit 38.

[0038] The user, with the central part of the retaining portion 40 protruding in the thickness direction, inserts one of the four corners 34 of the card 24 that is close to the first slit structure 32a into the openings of the first slit 36 ​​and the second slit 38. More specifically, the user slides the card 24 along the card placement surface 28 to insert one corner 34 into the first slit 36. This guides one corner 34 of the card 24 from the card placement surface 28 to the back surface 30. If the user slides the card 24 further, one corner 34 of the card 24 will pass through the second slit 38. This guides one corner 34 of the card 24 from the back surface 30 to the card placement surface 28. As described above, the first slit 36 ​​and the second slit 38 are wide open (see Figure 6). This allows the tip end of one corner 34 of the card 24 to easily pass through the first slit 36 ​​and the second slit 38 without contacting the edges of the first slit 36 ​​and the second slit 38.

[0039] Subsequently, when the user releases their hand from the pressing part 40, the central part of the pressing part 40 displaces toward the card 24 in the thickness direction. As a result, as shown in Figure 5C, the pressing part 40 makes surface contact with one corner 34 of the card 24. Consequently, one corner 34 of the card 24 is pressed in the thickness direction by the pressing part 40. As described above, one corner 34 of the card 24 is inserted through the first slit 36 ​​and the second slit 38. Therefore, when the pressing part 40 presses one corner 34 of the card 24 in the thickness direction, one corner 34 of the card 24 is held in a state where it is sandwiched between the first slit 36 ​​and the second slit 38. Moreover, the card 24 is held with both its center and the tip of one corner 34 positioned on the card placement surface 28. This allows the card 24 to be held on the card placement surface 28 in a clean state while properly protecting one corner 34 of the card 24.

[0040] Next, the user has the second slit structure 32b or the third slit structure 32c hold the other corner 34 of the card 24. In this case, the user has the second slit structure 32b or the third slit structure 32c hold the other corner 34 of the card 24 in the same manner as the first slit structure 32a holds the other corner 34 of the card 24. Therefore, a detailed explanation of how the second slit structure 32b or the third slit structure 32c holds the other corner 34 will be omitted.

[0041] In the first embodiment, the other corner 34 of the card 24 may be held first in the second slit structure 32b or the third slit structure 32c, and then the other corner 34 of the card 24 may be held in the first slit structure 32a.

[0042] The first embodiment provides the following effects.

[0043] As shown in Figure 1, the first slit 36 ​​and the second slit 38 are curved convexly in opposite directions. Therefore, as shown in Figure 6, when the user bends the back cover 22 so that the slit structure 32 narrows, the pressing portion 40 curves and protrudes more than the rest of the back cover 22 in the thickness direction. As a result, the first slit 36 ​​and the second slit 38 open sufficiently, so as shown in Figure 5C, the user can easily pass the corners 34 of the card 24 through the first slit 36 ​​and the second slit 38 with the card 24 placed on the card placement surface 28. Furthermore, after passing the corners 34 of the card 24 through the first slit 36 ​​and the second slit 38, when the user releases their hand from the back cover 22, the pressing portion 40 presses the corners 34 of the card 24 in the thickness direction of the back cover 22. As a result, the card 24 is held with both the center of the card 24 and the tip of the corner 34 of the card 24 placed on the card placement surface 28. Therefore, in the first embodiment, it becomes possible to properly protect the corners 34 of the card 24 while keeping the card 24 in a clean condition. In addition, the card 24 can be quickly held in the card holding part 26.

[0044] As shown in Figures 2 and 3, the first slit 36 ​​has a pair of first extensions 42 extending from both ends of the first slit 36 ​​toward the center of the card 24. The second slit 38 has a pair of second extensions 44 extending from both ends of the second slit 38 toward the center of the card 24.

[0045] This makes it easier to make the pressing portion 40 protrude in the thickness direction of the back cover 22 while ensuring the mechanical strength of the pressing portion 40. In addition, it is possible to avoid damage to the back cover 22 due to cracks forming in the direction of extension of the first slit 36 ​​and the second slit 38 from both ends of the first slit 36 ​​and the second slit 38 on the back cover 22.

[0046] The card 24 is rectangular in shape, and the two slit structures 32 are positioned diagonally across the card 24.

[0047] This makes it easier to hold one corner 34 of the card 24 with the first slit structure 32a, and to hold the other corner 34 of the card 24 with the second slit structure 32b or the third slit structure 32c.

[0048] (Second Embodiment) The file 10B according to the second embodiment will be described with reference to Figure 7. In the file 10B according to the second embodiment, the same reference numerals are used for components that are the same as those in the file 10A according to the first embodiment (see Figures 1 to 6), and detailed explanations are omitted below.

[0049] The file 10B according to the second embodiment is a clear holder for storing thin items. The file 10B is constructed by overlapping two rectangular sheets 50 and joining two sides of the two sheets 50. The file 10B according to the second embodiment includes a card holding portion 52. In the second embodiment, the card holding portion 52 is provided on one of the two sheets 50. Also, in the second embodiment, the outer surface 50b of one of the sheets 50 is the card placement surface 54 (front surface). Therefore, in the second embodiment, the inner surface 50a of one of the sheets 50 is the back surface 56.

[0050] In the second embodiment, the card holder 52 has a plurality of slit structures 32 (first slit structure 32a, second slit structure 32b, third slit structure 32c). In Figure 7, the first slit structure 32a, the second slit structure 32b, and the third slit structure 32c are arranged in the corner of one sheet body 50 near the spine 58 of the file 10B. The card 24 is held by the first slit structure 32a and the second slit structure 32b or the third slit structure 32c while placed on the card placement surface 54.

[0051] The second embodiment is not limited thereto. Multiple slit structures 32 may be arranged at any location on one of the sheet bodies 50. Alternatively, multiple slit structures 32 may be arranged on the other of the two sheet bodies 50. Furthermore, multiple slit structures 32 may be arranged on each of the two sheet bodies 50.

[0052] In the second embodiment, the same effects as in the first embodiment can be obtained. In addition, since the card 24 is held on the outer surface 50b (card placement surface 54) of the sheet body 50, the card 24 is more easily visible from outside the file 10B.

[0053] (Third embodiment) As shown in Figure 8, the file 10C according to the third embodiment is a file for storing cards 24 such as trading cards and photographs. The file 10C according to the third embodiment is an album or booklet for storing cards 24. The file 10C according to the third embodiment has a cover body 60 and a plurality of backing sheets 62.

[0054] The cover body 60 has a front cover 64, a back cover 66, and a spine 68. The spine 68 connects the front cover 64 and the back cover 66. The multiple backing sheets 62 are rectangular thin sheets made of paper or resin. The multiple backing sheets 62 are connected to the spine 68 between the front cover 64 and the back cover 66. With the cover body 60 open, the multiple backing sheets 62 can rotate between the front cover 64 and the back cover 66, with the spine 68 as the pivot point.

[0055] The file 10C according to the third embodiment includes a card holding section 70. The multiple backing sheets 62 are collection backing sheets capable of holding multiple cards 24. Each of the multiple backing sheets 62 is a sheet body 72 provided with a card holding section 70. The card holding section 70 has multiple slit structures 32. In the third embodiment, of the two surfaces of the sheet body 72 (backing sheet 62), one surface that can face the front cover 64 is the card placement surface 74 (front surface). Of the two surfaces of the sheet body 72, the other surface that can face the back cover 66 is the back surface 76.

[0056] In the third embodiment, three slit structures 32 (first slit structure 32a, second slit structure 32b, and third slit structure 32c) are treated as one set, and multiple sets of slit structures 32 are arranged on the sheet body 72. In Figure 8, four sets of slit structures 32 are arranged on a single sheet body 72 with spaces between them. In the third embodiment, a card 24 is held in each of the four sets of slit structures 32 on a single sheet body 72. Therefore, a maximum of four cards 24 can be held on a single sheet body 72.

[0057] The third embodiment is not limited thereto. The sheet body 72 may have at least one set of slit structures 32.

[0058] In the third embodiment, the same effects as in the first embodiment can be obtained. In the third embodiment, multiple sets of slit structures 32 are provided on a single sheet 72. As a result, by providing multiple sheet 72 in the file 10C, more cards 24 can be held in the file 10C.

[0059] The following additional information is disclosed regarding the above embodiments.
