Description

[Technical Field]

[0001] The present invention relates to a holder and a combination of the holder and a printed material. [Background technology]

[0002] Conventionally, typical saddle-stitched calendars have a picture of a painting or landscape at the top and a display of the date, day of the week, etc. at the bottom, and most have a through-hole in the center of the top for hanging when in use. When hanging such saddle-stitched calendars, they are often used by hooking the through-hole of the calendar onto a hook fixed to the wall or a protruding object with a nail or screw attached (see, for example, Patent Document 1). In some cases, the calendar is hung by inserting a thumbtack into the through-hole of the calendar, rather than hanging it on a hook or protruding object.

[0003] When using a saddle-stitched calendar, the lower calendar paper is turned up every one or two months and the through-hole of the calendar paper is hooked onto a protrusion such as a hook, or after turning up the calendar paper, the thumb tack is removed, the through-hole of the turned-up calendar paper is aligned with the through-hole of the upper calendar, and the thumb tack is then inserted again into the through-hole to hang it.

[0004] [Patent Document 1] Patent No. 6379380 Summary of the Invention [Problem to be solved by the invention]

[0005] However, over time, the top corners of the calendar may begin to curl forward. This phenomenon occurs frequently, especially in the summer. It is thought to be caused by the humid air supplied by the air conditioner, which often hits the calendar directly. Once the top of the calendar curls, it will not return to its original shape.

[0006] The present invention has been made to solve the above problems, and aims to provide a holder that can suppress curling that occurs in printed matter over time, and a combination of the holder and the printed matter. [Means for solving the problem]

[0020] A holder according to an embodiment of the present invention and a combination of such a holder and a printed material will be described below with reference to the drawings. Fig. 1 is a schematic diagram of the holder according to this embodiment, Fig. 2 is an enlarged view of a portion of the holder in Fig. 1, Figs. 3, 4, 6, and 8 are schematic diagrams of other holders according to this embodiment, Fig. 5 is an enlarged view of a portion of the holder in Fig. 4, Fig. 7 is an enlarged view of a portion of the holder in Fig. 6, Fig. 9 is an enlarged view of a portion of the holder in Fig. 8, and Fig. 10 is a view showing the holder according to this embodiment in use.

[0021] <<Holder>> The holder 10 shown in FIG. 1 holds printed materials by clamping them. In this specification, "printed materials" refers to paper and materials printed on materials other than paper. The thickness of the printed materials is preferably, for example, 10 mm or less. The lower limit of the thickness of the printed materials is not particularly limited, but may be, for example, 0.1 mm or more. Examples of printed materials include, but are not particularly limited to, booklets such as calendars and documents, posters, cards, etc. The holder 10 is particularly suitable for holding saddle-stitched booklets such as saddle-stitched calendars.

[0022] The holder 10 comprises a holder main body 11 and two or more clamping pieces 12 that clamp a printed material between the holder main body 11 and the clamping pieces 12. The holder 10 shown in Fig. 1 is made up of a single elastic, long plate-like member.

[0023] Letters, indications, etc. may be printed or imprinted on the front surface 10A or the back surface (not shown) of the holder 10. Letters, etc. may be printed or imprinted on at least one of the holder main body 11 and the clamping piece 12. If the holder main body 11 and the clamping piece 12 are made of vulcanized fiber, which will be described later, the letters, etc. can be printed by a laser, and if they are made of eliplastic paper, which will be described later, the letters, etc. can be printed by a normal printing technique.

[0024] <Holder body> The shape of the holder main body 11 is not particularly limited, but may be, for example, a long plate. The holder main body 11 shown in FIG. 1 is horizontally elongated, specifically rectangular. The length of the holder main body 11 in the longitudinal direction DR1 may be, for example, 100 mm or more and 550 mm or less, depending on the size of the printed material. The lower limit of the length of the holder main body 11 in the longitudinal direction DR1 may be 180 mm or more, 250 mm or more, or 290 mm or more, and the upper limit of the length of the holder main body 11 in the longitudinal direction DR1 may be 520 mm or less, 450 mm or less, or 420 mm or less. If the length of the holder main body 11 in the longitudinal direction DR1 is approximately the same as the width of the printed material, curling over time can be more effectively suppressed, and the holder main body 11 can be packaged together with the printed material, facilitating transportation. For this reason, it is preferable that the length of the holder main body 11 in the longitudinal direction DR1 be within ±80 mm of the width of the printed material. This length is the average value of the lengths of the holder main body 11 in the longitudinal direction DR1 measured at five random locations.

[0025] The length of the holder main body 11 in the short side direction DR2 is not particularly limited, but is preferably 30 mm or more from the viewpoint of ensuring strength and being able to form a clamping piece 12 of a certain size. The lower limit of the length of the holder main body 11 in the short side direction DR2 may be 35 mm or more, 40 mm or more, or 45 mm or more, and the upper limit of the length of the holder main body 11 in the short side direction DR2 may be 80 mm or less, 75 mm or less, or 70 mm or less. This length is the average value of the lengths of the holder main body 11 in the short side direction DR2 measured at five random locations.

[0026] The thickness of the holder main body 11 is preferably 0.5 mm or more and 1.5 mm or less. If the thickness of the holder main body 11 is 0.5 mm or more, curling of the printed matter over time can be further suppressed. The lower limit of the thickness of the holder main body 11 is more preferably 0.75 mm or more, 0.80 mm or more, or 0.95 mm or more, and the upper limit of the thickness of the holder main body 11 is more preferably 1.3 mm or less, 1.1 mm or less, or 1.0 mm or less. The thickness is the average value of thicknesses measured at five random locations.

[0027] The holder main body 11 has a first edge 11A in the longitudinal direction DR1 of the holder main body 11, a second edge 11B opposite to the first edge 11A, a third edge 11C in the lateral direction of the holder main body 11, and a fourth edge 11D opposite to the third edge 11C. In the holder main body 11 of FIG. 1, the first edge 11A and the second edge 11B extend in the lateral direction DR2 of the holder main body 11, and the third edge 11C and the fourth edge 11D extend in the longitudinal direction DR1 of the holder main body 11.

[0028] A first through hole 11E for fixing the holder 10 to a wall is formed in the holder main body 11. The shape and size of the first through hole 11E are not particularly limited, but it is preferable that the first through hole 11E be circular and have a diameter of 5.0 mm to 12 mm. If the size of the first through hole 11E is within the above range, the holder 10 can be fixed to the wall with a thumb tack or the like through the first through hole 11E.

[0029] The first through hole 11E is preferably located in the center of the holder main body 11. The first through hole 11E is preferably formed at a position where the distance d1 (see FIG. 2) from the third edge 11C and the distance d2 (see FIG. 2) from the fourth edge are each 5.0 mm or more. By forming the first through hole 11E at such a position, curling that occurs over time in printed materials can be further suppressed, and the holder 10 can withstand the weight of the printed materials even when they are held therein.

[0030] <Holding piece> As described above, the clamping pieces 12 clamp the printed material between the holder main body 11 and the clamping pieces 12. The clamping pieces 12 are surrounded by the holder main body 11, and two or more clamping pieces 12 are provided. Specifically, the clamping pieces 12 are respectively arranged in a first region between the first through hole 11E and the first edge 11A and a second region between the first through hole 11E and the second edge 11B in the longitudinal direction DR1 of the holder main body 11. Furthermore, as long as there are two or more clamping pieces 12, three, four, five, or more clamping pieces 12 may be provided. For example, when the number of clamping pieces 12 is an even number, it is preferable that the same number of clamping pieces 12 be arranged in the first region and the second region. The more clamping pieces 12 there are, the more curling that occurs over time in the printed material can be suppressed. However, since a larger portion of the printed material is hidden by the clamping pieces 12, the number of clamping pieces 12 is preferably four or less.

[0031] The clamping pieces 12 are continuous with the holder main body 11. Specifically, each of the clamping pieces 12 is continuous with the holder main body 11 at its root 12A on the third edge 11C side in the short direction DR2 of the holder main body 11. That is, the root 12A of all of the clamping pieces 12 are located on the third edge 11C side. By having the holder main body 11 and the clamping pieces 12 be continuous, the number of parts can be reduced and printed materials can be easily attached to the holder 10.

[0032] The clamping piece 12 is continuous with the holder main body 11 at the base 12A, but is separated from the holder main body 11 in areas other than the base 12A. In the clamping piece 12 having this structure, the printed matter can be held by the clamping piece 12 and the holder main body 11 by inserting the printed matter between the clamping piece 12 and the holder main body 11 from the tip 12B side of the clamping piece 12. The tip 12B is located closer to the fourth edge 11D than the base 12A.

[0033] The shape of the clamping piece 12 is not particularly limited and may be, for example, an arc or a rectangle. In addition, since the printed matter may display a pattern, it is preferable that the clamping piece 12 has a hollow portion 12C in order to reduce the portion that overlaps with the printed matter and prevent the pattern of the printed matter from being hidden.

[0034] The clamping piece 12 shown in FIG. 1 has an arc shape with a hollow portion 12C. The hollow portion 12C is a through hole. When the clamping piece 12 has this shape, the width W1 (see FIG. 2) of the clamping piece 12 is preferably 3.0 mm or more and 10 mm or less. If the width W1 of the clamping piece 12 is 3.0 mm or more, strength can be ensured. If it is 10 mm or less, concealment of the image on the printed material can be prevented. In this case, the lower limit of the width W1 of the clamping piece 12 is preferably 3.5 mm or more, 4.0 mm or more, or 4.5 mm or more, and the upper limit is preferably 9.5 mm or less, 9.0 mm or less, or 8.5 mm or less. The width W1 of the clamping piece 12 is the average value of the widths of the clamping piece 12 measured at five random locations.

[0035] When the clamping piece 12 has a cutout portion 12C, the maximum length L1 (see FIG. 2) of the cutout portion 12C in the short-side direction DR2 is preferably 5.0 mm or more and 15 mm or less. If the maximum length L1 of the clamping piece 12 is 5.0 mm or more, it improves manufacturing versatility, while if it is 15 mm or less, it prevents the image on the printed material from being hidden. In this case, the lower limit of the maximum length L1 of the clamping piece 12 is more preferably 5.5 mm or more, 6.0 mm or more, or 6.5 mm or more, and the upper limit is more preferably 14.5 mm or less, 14.0 mm or less, or 13.5 mm or less. The maximum length L1 of the cutout portion 12C refers to the maximum length measured at five points within the portion considered to be the maximum length L1 of the cutout portion 12C.

[0036] When the clamping piece portion 12 is arc-shaped with a hollow portion 12C, the radius of curvature R (see Figure 2) of the clamping piece portion 12 is preferably 5.0 mm or more and 15 mm or less for the same reasons as the maximum length L1, and it is more preferable that the lower and upper limits of the radius of curvature R of the clamping piece portion 12 are the same as the maximum length L1.

[0037] The thickness of the clamping piece 12 is the same as the thickness of the holder main body 11, so a description thereof will be omitted here. The thickness of the clamping piece 12 is the average value of the thicknesses of the clamping piece 12 measured at five random points.

[0038] As described above, the holder main body 11 and the clamping piece 12 are preferably formed from a single long plate-like member. The material of the holder main body 11 and the clamping piece 12 is not particularly limited, but given the current growing social demand for a plastic-free society due to environmental considerations, a paper material is preferred from the perspective of plastic-free use. Paper materials also include paper that has undergone special treatment. Examples of paper materials include cardboard, vulcanized fiber, and elastomer paper. Among these, vulcanized fiber is preferred from the viewpoint of high strength, and elastomer paper is preferred from the viewpoint of high density, rigidity, and favorable printability and processing suitability.

[0039] Vulcanized fiber is a tough sheet obtained by, for example, making raw paper from cotton pulp or wood pulp without sizing, laminating the raw paper, immersing the paper in a concentrated solution of zinc chloride (generally Baume degree 65 to 74), causing the surface of the plant fibers of the raw paper to swell (gelatinize) with the zinc chloride, and then pressing the resulting paper together. The zinc chloride is removed by rinsing with water, and the resulting paper is then wound up and dried. Elipla paper is a high-density cardboard.

[0040] <Second through hole> A second through hole 13 having a width W2 (see FIG. 2) of 1.0 mm or more and 10 mm or less is preferably provided between the holder main body 11 and the clamping piece 12. Even if the thickness of the printed material to be clamped between the holder main body 11 and the clamping piece 12 is large, the presence of such a second through hole 13 allows the printed material to be clamped while maintaining strength. The lower limit of the width W2 of the second through hole 13 is more preferably 1.5 mm or more, 2.0 mm or more, or 2.5 mm or more, and the upper limit is more preferably 9.5 mm or less, 9.0 mm or less, or 8.5 mm or less. The width W2 is particularly preferably 3.0 mm or more and 8.0 mm or less. The width W2 of the second through hole 13 is the average value of the widths W2 of the second through hole 13 measured at five random locations.

[0041] <Other holders> The first through hole 11E shown in FIG. 1 is located in the center of the holder body 11. However, as in the holder 20 shown in FIG. 3, a protrusion 11F may be formed on the holder body 11 in the short-side direction DR2, and the first through hole 11E may be formed in the protrusion 11F. The holder 20 is surrounded by the holder body 11 and further includes a protrusion 21 for hanging a printed material. The printed material can be hung by inserting the protrusion 21 into a through hole provided in the printed material. The protrusion 21 is continuous with the holder body 11. The protrusion 21 is located closer to the fourth edge 11D than the first through hole 11E, and the base of the protrusion 21 is located closer to the fourth edge 11D than the tip of the protrusion 21. The thickness of the protrusion 21 may be equal to or smaller than the width of the through hole provided in the printed material. A third through hole 22 may be formed between the holder body 11 and the protruding piece 21 .

[0042] While the clamping piece 12 shown in FIG. 1 is hollow, the clamping piece 31 may be arc-shaped without a hollow core, as in the holder 30 shown in FIG. 4. If the clamping piece 31 is arc-shaped without a hollow core, it can be stronger than the clamping piece 12 with an arc-shaped core. The maximum length L2 of the clamping piece 31 (see FIG. 5) is preferably 5.0 mm or more and 15.0 mm or less. If the maximum length L2 of the clamping piece 31 is 5.0 mm or more, the holding force can be ensured, and if it is 15.0 mm or less, the image on the printed material can be prevented from being hidden. In this case, the lower limit of the maximum length L2 of the clamping piece 31 is preferably 5.5 mm or more, 6.0 mm or more, or 6.5 mm or more, and the upper limit is preferably 14.5 mm or less, 14.0 mm or less, or 13.5 mm or less. The maximum length L2 of the clamping piece 31 indicates the maximum length measured at five points on the portion of the clamping piece 31 that is considered to have the maximum length.

[0043] The clamping piece 31 has a base portion 31A and a tip portion 31B. The base portion 31A is similar to the base portion 12A, and the tip portion 31B is similar to the tip portion 12B, so a description thereof will be omitted here.

[0044] Furthermore, the clamping pieces 41, 51 may be rectangular, as in the holder 40 shown in Fig. 6 and the holder 50 shown in Fig. 8. In the rectangular clamping pieces 41, 51, the tip corners of the clamping pieces are preferably rounded or chamfered to ensure safety, as in the clamping piece 41. The clamping piece 41 has a shape that is long in the short-side direction DR2 of the holder main body 11 as shown in Fig. 6, and the clamping piece 51 has a shape that is long in the longitudinal direction DR1 of the holder main body 11 as shown in Fig. 8.

[0045] It is preferable that root portion 41A of clamping piece 41 has notch 41A1. That is, it is preferable that the width of root portion 41A of clamping piece 41 is smaller than the width of tip portion 41B of clamping piece 41. In rectangular clamping pieces, force is applied to the root portion, which can cause the edge of the root portion to break, but by using the above-described structure, force is less likely to be applied to root portion 41A, making it less likely to break.

[0046] The width W3 of the clamping piece 41 in the longitudinal direction DR1 (see FIG. 7) is preferably 5.0 mm or more and 50 mm or less. If the width W3 of the clamping piece 41 is 5.0 mm or more, a minimum holding force against sagging can be ensured, and if it is 50 mm or less, the image on the printed material can be prevented from being hidden. The lower limit of the width W3 of the clamping piece 41 is preferably 10 mm or more, 15 mm or more, or 20 mm or more, and the upper limit is preferably 45 mm or less, 40 mm or less, or 35 mm or less. The width W3 of the clamping piece 41 is the average value of the widths W3 of the clamping piece 41 measured at five random locations.

[0047] The length L3 (see FIG. 7) of the clamping piece 41 in the short direction DR2 is preferably 5.0 mm or more and 50 mm or less for the same reasons as for the width W3. The preferred upper and lower limits of the length L3 of the clamping piece 41 are the same as those of the width W3. The length L3 of the clamping piece 41 is the average value of the lengths L3 of the clamping piece 41 measured at five random locations.

[0048] As shown in Figure 6, the clamping piece portion 41 has a root portion 41A and a tip portion 41B, but except as specifically noted above, the root portion 41A is the same as the root portion 12A, and the tip portion 41B is the same as the tip portion 12B, so their explanation will be omitted here.

[0049] The second through hole 42 between the holder main body 11 and the clamping piece 41 differs from the second through hole 13 only in shape, and the width W4 of the second through hole 42 (see Figure 7) is the same as the width W2 of the second through hole 13.

[0050] The width W5 of the clamping piece 51 in the longitudinal direction DR1 (see FIG. 8) may be 30 mm or more and 255 mm or less, and the length L4 of the clamping piece 51 in the lateral direction DR2 (see FIG. 9) may be 5 mm or more and 50 mm or less. The width W5 of the clamping piece 51 is the average value of the widths W5 of the clamping piece 51 measured at five random locations, and the length L4 of the clamping piece 51 is the average value of the lengths L4 of the clamping piece 51 measured at five random locations.

[0051] 8, the clamping piece 51 has a base portion 51A and a tip portion 51B. The base portion 51A is similar to the base portion 12A, and the tip portion 51B is similar to the tip portion 12B, so a description thereof will be omitted here.

[0052] The second through hole 52 between the holder main body 11 and the clamping piece 51 differs from the second through hole 13 only in shape, and the width W6 of the second through hole 52 (see Figure 9) is the same as the width W2 of the second through hole 13.

[0053] The holders 10, 20, 30, 40, and 50 can be obtained by punching or laser processing a single long plate-shaped member. Specifically, predetermined portions of the long plate-shaped member are punched or laser processed to form the holder main body 11 having the first through hole 11E, the clamping pieces 12, 31, 41, and 51, and the second through holes 13, 42, and 52. This allows the holders 10, 20, 30, 40, and 50 to be formed. In this case, laser processing is suitable when vulcanized fiber is used as the long plate-shaped member, and punching is suitable when eliplastic paper is used.

[0054] Such a holder 10 can be used as shown in Fig. 10. First, the holder 10 is fixed to the wall with a thumb tack P or the like via the first through hole 11E of the holder main body 11. If the holder main body 11 does not have a protrusion 11F for hanging the printed matter PR, the holder 10 and the printed matter PR are fixed to the wall with a thumb tack P or the like after aligning the through hole PR1 in the printed matter PR with the first through hole 11E of the holder main body 11. If the holder main body 11 has a protrusion 11F for hanging the printed matter PR, the holder 10 is fixed to the wall with a thumb tack P or the like via the first through hole 11E of the holder main body 11, and then the protrusion 21 is inserted into the through hole PR1 in the printed matter PR to hang the printed matter PR.

[0055] Thereafter, the upper part of the printed matter PR is clamped between the holder main body 11 and the clamping piece 12. If the printed matter PR is a booklet, for example, a saddle-stitched calendar, the page can be turned over and the turned page can be clamped between the holder main body 11 and the clamping piece 12, so that the desired page is opened.

[0056] According to this embodiment, the holder is surrounded by the holder main body 11 and is provided with two or more clamping pieces 12, 31, 41, 51 that clamp the printed material between the holder main body 11, and the clamping pieces 12, 31, 41, 51 are each continuous with the holder main body 11, so that when the upper part of the printed material is clamped between the holder main body 11 and the clamping pieces 12, 31, 41, 51, curling that occurs over time in the printed material can be suppressed.

[0057] <<Union>> The combination may include the holders 10, 20, 30, 40, and 50 and the printed material held by the holders 10, 20, 30, 40, and 50. [Example]

[0058] In order to explain the present invention in detail, examples are given below, but the present invention is not limited to these descriptions.

[0059] Example 1 First, a 0.8 mm thick plate-shaped vulcanized fiber (manufactured by Hokuetsu Toyo Fiber Co., Ltd.) was prepared. Next, a holder body having a first through hole, a clamping piece, and a second through hole were formed by laser processing, as shown in Figure 1. The holder body measured 35 mm long and 400 mm wide. The first through hole was circular and 6 mm in diameter, and the distance d1 from the third edge of the holder body in the lateral direction to the first through hole was 16 mm. The widths from the first edge to the second through hole in the longitudinal direction of the holder body and from the second edge to the second through hole were both 10 mm. The clamping piece was semicircular with a hollowed-out center. The maximum length L1 of the hollowed-out portion in the lateral direction of the holder body was 9.0 mm, and the width W1 of the clamping piece was 3.0 mm. The width W2 of the second through hole was 5.0 mm.

[0060] On the other hand, an A3-sized saddle-stitched calendar (A2 double-page spread, 28 pages) was prepared. This calendar had a photograph on the top page when spread, and a calendar section showing the days of the month and the days of the week on the bottom page. Then, with pages 24 and 25 displayed when spread, the first through-hole in the holder was aligned with the hanging through-hole in the calendar, and pages 1 to 24 of the calendar were clamped between the holder main body and clamping piece, to obtain a calendar with a holder.

[0061] <Example 2> In Example 2, a calendar with a holder was obtained in the same manner as in Example 1, except that vulcanized fiber having a thickness of 1.0 mm (manufactured by Hokuetsu Toyo Fiber Co., Ltd.) was used instead of the vulcanized fiber having a thickness of 0.8 mm.

[0062] Example 3 In Example 2, a calendar with a holder was obtained in the same manner as in Example 1, except that Eripura paper (T-mesh) (Daioh Paper Co., Ltd.) having a thickness of 0.42 mm was used instead of the vulcanized fiber.

[0063] Example 4 In Example 4, a calendar with a holder was obtained in the same manner as in Example 1, except that a paperboard having a thickness of 0.395 mm was used instead of the vulcanized fiber.

[0064] <Comparative Example 1> In Comparative Example 1, no holder was provided, and the same calendar as in Example 1 was used.

[0065] <Environmental Testing> An environmental test was conducted on the holder-attached calendars of Examples 1 to 4 and the calendar of Comparative Example 1. Specifically, first, the holder-attached calendars of Examples 1 to 4 and the calendar of Comparative Example 1 were hung with hooks in an environmental tester (product name "HIFLEX NEO", manufactured by Kusumoto Chemicals Co., Ltd.). The holder-attached calendars of Examples 1 to 4 were hung with hooks via the first through-hole of the holder and the hanging hole of the calendar, while the calendar of Comparative Example 1 was hung with hooks via the hanging hole of the calendar. Thereafter, the inside of the environmental tester was maintained at a temperature of 40°C and a relative humidity of 80% for 6 hours, and then maintained at a temperature of 0°C for 9 hours. This cycle was repeated three times. After the environmental test, the holder-attached calendars of Examples 1 to 4 and the calendar of Comparative Example 1 were placed on a flat table, and the amount of curl was measured. The amount of curl was determined by measuring the distance between each of the top corners of the calendar and the table and averaging the measured values. Before the environmental test, the holder-attached calendars according to Examples 1 to 4 and the calendar according to Comparative Example 1 were so flat that the amount of curl could not be measured.

[0066] The results are shown in Table 1 below. [Table 1]

[0067] The results are described below. As shown in Table 1, the calendar according to Comparative Example 1 did not have a holder attached, so the amount of curl after the environmental test was large. In contrast, the calendars with holders according to Examples 1 to 4 had a smaller amount of curl after the environmental test than the calendar according to Comparative Example 1, so it was confirmed that curling that occurs over time in calendars can be suppressed.

[0068] Furthermore, as shown in Table 1, the holder-attached calendars of Examples 1 to 3 had a smaller amount of curl after the environmental test than the holder-attached calendar of Example 4, confirming that the holders of Examples 1 to 3 can better suppress curling that occurs over time in calendars.

[0069] Furthermore, as shown in Table 1, the holder-attached calendars of Examples 1 and 2 had a smaller amount of curl after the environmental test than the holder-attached calendar of Example 3, confirming that the holders of Examples 1 and 2 can further suppress curling that occurs over time in calendars.
