The illustrative embodiments of the present invention are described in detail below while referring to the drawings, but the invention is not limited to the embodiments.

First embodiment

Fig. 1 is a plan view of an index sticker according to a first embodiment. 2 to 4 are cross-sectional views at lines II-II, III-III, and IV-IV in Fig. 1, respectively. As illustrated in FIGS. 1 through 4, the index sticker 1 includes a body 2 and an adhesive layer 3 disposed on the entire rear surface of the body 2 and disposed on the protective release liner 4. The liner 4 can be treated, coated on its top surface (for example, coated with a thin layer of release material such as polyoxyxylene resin or the like) to release the desired The adhesive property is imparted to the adhesive layer 3 so that the index sticker 1 can be removed from the adhesive layer 3 while keeping the adhesive layer 3 intact. The liner 4 facilitates the handling and preparation of the index sticker 1. For example, the desired mark can be applied to the first display area 11 before the index pad 1 is separated from the pad 4. An assembly comprising two or more index stickers disposed on the liner 4 can be prepared, for example, by passing through a printer.

As illustrated in FIG. 1, the body 2 includes a first display area 11, a second display area 12, a first fastening area 13, a second fastening area 14, a first reinforcement area 15, and a second reinforcement area 16. A grid line or the like can be pre-printed on the body 2.

The first display area 11 is an area for writing a title with a pencil or a pen or the like, or for printing a title with a printer, and filling the current title (see FIG. 7) when the index sticker 1 is fastened to the sheet S. . The first display area 11 has a trapezoidal shape including a first edge 11a and a second edge 11b parallel to the Y direction (first direction) (that is, the first display area 11 is distinguished from the first fastening area 13 respectively) And a periphery of the second display area 12) and a third edge 11c and a fourth edge 11d extending obliquely (not parallel) in the X direction (second direction) (ie, distinguishing the outer edge of the first display area 11 (rim) The X direction is orthogonal to the Y direction adjacent to or adjacent to the first reinforcement region 15 and the second reinforcement region 16, respectively. The width of the first edge 11a of the first display area 11 is, for example, W1.

The second display area 12 is for writing a title with a pencil or a pen or the like, or for printing a title with a printer (similar to the first display area 11), and fastened to an index sticker 1 such as a book or a notebook. The sheet S of the memo note, file, etc. serves as the area of the back title (ie, opposite the first display area) (see FIG. 8). The second display area 12 has a shape that is axisymmetric with respect to the boundary line with the first display area 11 (ie, the second edge 11b) and the first display area 11, and has a shape Have the same trapezoidal shape. For convenience of explanation, in FIG. 1, the boundary between the first display area 11 and the second display area 12, the first fastening area 13 and the second fastening area 14, and the areas of the first reinforcement area and the second reinforcement area are used. Indicated by the dotted line. A curved line (eg, a perforated eye line, a score or a partial cut, etc.) may be formed in the body 2 at the second edge 11b between the first display area 11 and the second display area 12 and at the lines 15a and 16a to facilitate The sticker 1 is folded to engage the opposite side of the sheet (not shown). The bend line facilitates the configuration of the initially indexed index 1 to engage the opposite side of the sheet. The lengths of the first display area 11 and the second display area 12 in the X direction are all L1.

As illustrated in Figures 1 and 2, the first fastening zone 13 fastens the index sticker 1 to the front side of the sheet S via the section 3a of the adhesive layer 3 (see Figure 5). The first fastening zone 13 is formed such that it is connected to the first edge 11a of the first display zone 11. The first fastening zone 13 has a rectangular shape in which the width W3 in the longitudinal direction is longer than the width W1 of the first display zone 11. Since the width is longer than the width of the display area 11 in this manner, in addition to the function of fastening the index sticker 1 to the sheet S, the first fastening region 13 is also used to reinforce the portion of the sheet S which is easily torn by convention.

The difference between the width W3 of the first fastening zone 13 and the width W1 of the first display zone 11 is typically from about 2 mm to about 30 mm, and is often preferably from about 5 mm to about 10 mm. It should be understood that index stickers having dimensions outside of this range may be used in accordance with the present invention. If the difference in width is too small, the desired benefits of sheet reinforcement and reduction in sheet tear are not obtained. If the difference between the width W3 and the width W1 is too large, the index sticker may obscure portions of the sheet or be more difficult to handle and apply.

As illustrated in Figures 1 and 4, the second fastening zone 14 secures the index sticker 1 to the rear side of the sheet S via the section 3b of the adhesive layer 3 (see Figure 8). The second fastening zone 14 has a rectangular shape that is axisymmetric with respect to the rectangular shape of the first fastening zone 13, wherein the second edge 11b serves as an axis of symmetry. The second fastening zone 14 is formed such that it is coupled to the first edge 12a of the second display zone 12. The first edge 12a is axisymmetric with respect to the first edge 11a, wherein the second edge 11b of the first display area 11 serves as an axis of symmetry. Similar to the first fastening zone 13, the second fastening zone 14 has a width W3 that is longer than the width W1 of the first display zone 11 and the second display zone 12. In other words, the width of the second fastening zone 14 is the same as the width of the first fastening zone 13.

Generally, as shown in such an embodiment, the lengths of the first fastening zone 13 and the second fastening zone 14 in the X direction are substantially equal (i.e., L2 as shown). In many embodiments, the L2 is from about 2 mm to about 20 mm, and sometimes from about 3 mm to about 15 mm, and more preferably from about 3 mm to about 10 mm. If the length L2 of the first fastening zone 13 and the second fastening zone 14 is too small, the resulting reinforcement of the sheets by their fastening zones may be insufficient, and there may be an undesired separation of the index stickers 1 from the sheets S. The situation. On the other hand, if the length L2 is too large, the index sticker 1 may tend to undesirably mask portions of the sheet S.

As illustrated in Figures 1 and 3, the first reinforcement zones 15 and 16 reinforce the fastening of the index stickers 1 to the sheets S. The first reinforcement region 15 is formed with an edge 15a connected to one of the first fastening regions 13 in the Y direction, and is disposed adjacent to the edge 11c of the first display region 11 in the Y direction. A slit between the first display region 11 and the first reinforcement region 15 is formed along the edge 11c, and thus the first display region 11 and the first reinforcement region 15 are separated from each other. The first reinforcement region 15 has a trapezoidal shape and is formed such that its first end from the first fastening region 13 side faces the X direction The two ends are inclined to the inside in the Y direction.

The perforated eyeliner may be formed on a dotted line of the side 15a between the first reinforcement region 15 and the first fastening region 13. The perforated eyeliner serves as a starting point when the first reinforcing region 15 is folded to the rear side of the sheet S after folding the second display region 12 to the rear side for fastening the index sticker 1 to the sheet S.

As illustrated in FIGS. 1 and 3, similar to the first reinforcement region 15, the second reinforcement region 16 is fastened to and covers the area of the top surface of the second fastening region 14 by the segment 3e of the adhesive layer 3 ( See Figure 8) to strengthen the fastening of the index sticker 1 to the sheet S. The second reinforcement region 16 has a trapezoidal shape that is axisymmetric with respect to the trapezoidal shape of the first reinforcement region 15, wherein the center line of the index sticker 1 in the Y direction serves as an axis of symmetry. The second reinforcement region 16 is formed to be connected to one edge 16a of the first fastening region 13 in the Y direction, and is disposed adjacent to the other edge 11d of the first display region 11 in the Y direction. A slit between the first display area 11 and the second reinforcement area 16 is formed along the edge 11d, so that the first display area 11 and the second reinforcement area 16 are separated from each other.

The perforated eyeliner can be formed on the dashed line of the edge 16a between the second reinforcement zone 16 and the fastening zone 13. The perforated eyeliner serves as a starting point when the second reinforcing region 16 is folded to the rear side after the second display region 12 is folded to the rear side for fastening the index sticker 1 to the sheet S.

The widths of the first reinforcement region 15 and the second reinforcement region 16 in the Y direction (the regions correspond to the edges 15a and 16a) are the same width W2, and the width W1 of the first display region 11 and the first reinforcement region 15 and The sum of the widths W2 and W2 of the second reinforcement zone 16 is equal to the width W3 of the first reinforcement zone 13 or the second reinforcement zone 14. The length L3 of the first reinforcement zone 15 and the second reinforcement zone 16 is usually a minimum of about 2 mm. And the maximum is twice the length L1 of the first display area and the second display area. The reason why the length L3 of the first reinforcement zone 15 and the second reinforcement zone 16 is not less than 2 mm is because if the length L2 is less than 2 mm, the reinforcement by the first reinforcement zone 15 and the second reinforcement zone 16 may be Insufficient. On the other hand, the reason why the length L3 of the first reinforcement region 15 and the second reinforcement region 16 is at most twice the length L1 is because if the length L3 is larger than twice the length L1, it becomes difficult to display on the same plane. Zones 11 and 12 or fastening zones 13 and 14 are effectively placed together. As illustrated in FIG. 1, if the length L3 of the first reinforcement zone 15 and the second reinforcement zone 16 is equal to the length L2 of the second fastening zone 14, or is slightly shorter, it is possible to prevent the first reinforcement zone 15 and the second reinforcement zone. The 16 protrudes from the second fastening zone 14 when folded, and it is possible to reduce the obscuration of the content on the sheet S to which it is fastened.

The application or mounting of the index of the present invention to the sheet S is illustrated in Figures 5-9.

First, the index sticker 1 is peeled off from the pad 4. Next, as illustrated in FIG. 5, the adhesive layer 3a on the first fastening region 13 of the index sticker 1 is fastened to the edge of the surface of the sheet S.

Next, as illustrated in FIG. 6, the second display area 12 and the second fastening area 14 are folded to the rear side with a broken line (perforated eye line) along the second edge 11b as a starting point. Due to this folding, the adhesive layer 3b corresponding to the second fastening region 14 contacts and adheres to the rear side of the sheet S. Due to this folding, the first display area 11 and the second display area 12 are also fastened to each other with the adhesive layer 3d or the like disposed therebetween.

Next, as illustrated in Figures 7 to 9, along the edges 15a and 16a The dotted line (perforated eye line) is folded as a starting point to fold the first reinforcement zone 15 and the second reinforcement zone 16 to the rear side. Due to this folding, the first reinforcing zone 15 and the second reinforcing zone 16 are fastened to the two edges of the second fastening zone 14, with the respective adhesive layers 3c and 3e being disposed therebetween. In Fig. 9, the adhesive layer 3 is omitted to simply explain the juxtaposition of the regions of the index stickers.

Alternatively, when the index sticker 1 is fastened to the sheet S, instead of the foregoing method, the second fastening region 14 may be first fastened to the sheet S before the first fastening region 13 is fastened to the sheet S, and may be The strength regions 15 and 16 are folded before folding the second display area 12 and the second fastening area 14.

As described above, the index sticker 1 according to the present embodiment includes the reinforcing regions 15 and 16 disposed adjacent to the third side 11c and the fourth side 11d of the first display region 11 and connected to the fastening region 13. Therefore, according to this embodiment of the index sticker 1, it is possible to arrange the reinforcing regions 15 and 16 close to the sheet S to which the index sticker 1 is attached, which is relatively easy to be broken by the edge of the index sticker 1, and thus it is possible to make it difficult Tearing the sheet S.

In the index sticker 1, the width W3 of the first fastening zone 13 and the second fastening zone 14 is equal to the sum of the width W1 of the first display zone 11 or the second display zone 12 and the widths W2 and W2 of the reinforcement zones 15 and 16. . Due to this configuration, it is possible to set the width W3 of the first fastening zone 13 and the second fastening zone 14 to be long, and it is possible to compactly secure the position for arranging the reinforcing zones 15 and 16.

In the index sticker 1, the reinforcing regions 15 and 16 have a trapezoidal shape, and are formed so as to be inclined toward the inside in the Y direction toward the second end in the X direction from the first end on the side of the fastening region 13. As a result, it is possible to disperse the deformation stress into the inside of the index sticker 1, so that it is possible to make the sheet S more difficult to tear, and the deformation should be The force can be easily concentrated at the boundary between the edge of the sheet S to which the index sticker 1 is fastened and the index sticker 1.

In the index sticker 1, the body 2 further includes a second display area 12 disposed axially symmetric about the first display area 11, wherein the second edge 11b of the first display area 11 serves as an axis of symmetry. As a result, for the index sticker 1, it is possible to provide a display area on both sides thereof.

Instance

The invention will be explained in further detail below in the working examples and comparative examples below.

Working example 1

First, an index sticker T1 having the configuration of the first embodiment described above was prepared, which has the size shown in Fig. 18a. Further, the index sticker T1 is a paper sticker and has a layered structure in which an acrylic pressure sensitive adhesive (acrylic adhesive) is applied to the bottom side of an 80 μm paper placed on an 80 μm liner, as shown in Fig. 19a. Explained in the middle.

Next, the photocopy paper P was cut into a shape of 200 mm × 70 mm as illustrated in FIG. Next, the index sticker T1 illustrated in Fig. 18a is fastened to the photocopy paper P. When tightened, the center line C1 of the index sticker T1 and the center line C2 of the photoprint paper P are configured to be collinear. Next, as illustrated in FIG. 20, the cut photo paper P is folded at the lines L1 and L2 in a manner inclined to the rear side.

Next, as illustrated in Fig. 21, a 150 mm × 70 mm stainless steel plate B having a dimension shorter than the photocopy paper P in the longitudinal direction was prepared. Next, the lines L1 and L2 of the photocopy paper P are stacked on the edge of the stainless steel plate B in the short direction, and the two edges P1 and P2 of the photocopy paper P are folded to the rear side of the stainless steel plate B, and by double-sided Tape to tighten. The photocopy paper P is folded in an inclined manner and fixed so that, as illustrated in Fig. 22, it forms a semi-domed shape, and an opening leads to the front portion of the drawing. The photocopy paper P is not fixed to the stainless steel plate B on the front side of the stainless steel plate B.

Next, as illustrated in FIGS. 20 and 22, the chuck H of the tensile test machine is fixed to the right half of the index sticker T1. The reason why the chuck H is eccentrically fixed in this manner is because the sheet S is frequently torn when the tightened index tab T1 is gripped eccentrically. The stainless steel plate B was placed on a horizontal plane, and then, as illustrated in Fig. 22, the solid was pulled at a rate of 100 mm/min in the vertical direction. The index to the chuck H is labeled T1. Next, it was found that the maximum intensity recorded when the photocopy paper P was torn was 10.5 N.

Comparison example C1

An index sticker T2 having the same configuration as that of the index sticker T1 in Working Example 1 (first embodiment) was prepared except that the reinforcement regions 15 and 16 were omitted. The size of the index sticker T2 is shown in Figure 18b. Further, the index sticker T2 is the same paper sticker as the working example 1, and the layer structure is as shown in Fig. 19a. Next, the same tensile test as that for the working example 1 was performed on the index sticker T2, and it was found that the maximum intensity recorded when the photocopy paper P was torn was 9.0 N.

Working example 2

Next, an index sticker T3 having a body having a two-layer structure made of paper and a plastic film is prepared. In other words, the index sticker T3 is a laminate, and as illustrated in Figure 19b, in addition to the layered construction of the acrylic pressure sensitive adhesive applied to the bottom surface of the 80 μm paper, the 20 μm OPP film also uses acrylic pressure sensitive adhesive. The agent was placed on top of the 80 μm paper. The dimensions of the index sticker T3 are shown in Figure 18a. Next, the same tensile test as the test for Working Example 1 was performed on the index sticker T3, and it was found that the maximum intensity recorded when the photocopy paper P was torn was 10.6 N.

Comparative example C2

An index sticker T4 having the same configuration as that of the index sticker T3 in Working Example 2 was prepared except that the reinforcement regions 25 and 26 were omitted. The size of the index sticker T4 is shown in Figure 18b. Further, the index sticker T4 is the same laminate as the working example 2, and the layer structure is as shown in Fig. 19b. Next, the same tensile test as the test for the working example 1 and the like is performed on the index sticker T4, and it is found that the photoprinting paper P is torn. The maximum intensity recorded at the time of splitting is 8.9 N.

In this way, by providing the reinforcing regions 15, 16, 25 and 26 in the index sticker, the maximum strength at the time of tearing is improved by 17% to 19% (about 20%), so it is confirmed that the index is tightly attached. The sheet S that is fixed is more difficult to tear.
