Description

[Technical field]

[0001] The present invention relates to a wristband. [Background technology]

[0002] Wristbands are used instead of admission tickets at event venues, concerts, etc. They are also used in medical institutions to identify patients and examinees (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2020-38386 A Summary of the Invention [Problem to be solved by the invention]

[0004] Wristbands such as that described in Patent Document 1 have a breaking slit formed in them so that the band portion breaks when an attempt is made to peel off the attached portion, to prevent unauthorized use by sharing the same among different users.

[0005] However, with conventional tearing notches, depending on the direction of peeling, it was sometimes possible to peel the tape off without tearing the attached portion, leaving room for improvement.

[0006] Therefore, the present invention aims to provide a wristband that is formed into a ring shape by attaching the end portion, which is the attachment part of the wristband, to a part of a band portion, so that when the end portion is pulled off from the band portion, the end portion is securely broken, so that it cannot be reused as a wristband. [Means for solving the problem]

[0007] According to one aspect of the present invention, there is provided a wristband comprising a strip-shaped band portion and an adhesive portion formed by laminating an adhesive to one end of the band portion, and formed into a ring shape by adhering the adhesive portion to a part of the band portion, wherein the end has a plurality of first breaking notches formed radially, the first breaking notches having two parallel first line segments and a second line segment connecting one ends of the first line segments and being longer than the first line segments, and wherein an opening formed by the first line segments and the second line segments is shaped to face the radial center. Effect of the Invention

[0008] According to the above aspect, the end of the band portion has two parallel first line segments and a second line segment that connects one end of the first line segments and is longer than the first line segment, and the first breaking notches are formed radially so that the opening formed by the first line segments and the second line segment face the radial center. Therefore, when the end is peeled from the band portion from the outer edge side of the end toward the inside, the end is torn at the second line segment of the first breaking notches, the tear spreads along the pair of first line segments, and the end is broken beyond the terminal portion of the first line segments. Because the first breaking notches are formed radially, when an attempt is made to peel the end of the wristband from the band portion, the end cannot maintain its state before it was attached, and cannot be formed into a ring shape again.

[0010] [Wristband] Fig. 1 is a plan view of a wristband 1 according to an embodiment of the present invention as viewed from the front side, Fig. 2 is a plan view of the wristband 1 as viewed from the back side, and Fig. 3 is a cross-sectional view taken along line III-III in Fig. 1.

[0011] In this embodiment, the front surface of wristband 1 is the surface on which a specific design or text is printed in advance, and the back surface of wristband 1 is the surface opposite to the front surface, which is the surface that comes into contact with human skin.

[0012] Wristband 1 has a strip-shaped band portion 11 and an adhesive portion 12 formed on the back surface of one end portion 11a of band portion 11.

[0013] As shown in Fig. 3, the band portion 11 is formed by laminating a thermal substrate 21 and a back substrate 22 with a laminate layer 23. A separator S is temporarily attached to the adhesive portion 12 formed on the back surface of the end portion 11a. For ease of understanding, the separator S is not shown in Fig. 1.

[0014] 3, the thermal substrate 21 has a thermosensitive coloring layer 21b provided on a surface substrate 21a. Therefore, the thermal substrate 21 on which the thermosensitive coloring layer 21b is disposed constitutes the surface of the wristband 1.

[0015] Materials that can be used for the surface substrate 21a include a single resin film such as polyvinyl chloride, polyethylene terephthalate, polypropylene, polyethylene, or polyethylene naphthalate, or a multilayer film formed by laminating a plurality of such resin films.

[0016] In addition to the above-mentioned resin film substrates, paper substrates such as cardboard, high-quality paper, medium-quality paper, or coated paper obtained by appropriately forming a coating layer on any of these may be used.

[0017] In this embodiment, the thickness of the surface substrate 21a can be from 10 μm to 300 μm. When paper is used as the surface substrate 21a, the thickness of the surface substrate 21a can be from 50 μm to 260 μm within the above range, and is usually preferably 80 μm.

[0018] When a resin film is used as the surface base material 21a, the thickness of the surface base material 21a may be from 25 μm to 200 μm within the above range, and more preferably from 10 μm to 200 μm. These thicknesses can be appropriately selected depending on the application.

[0019] The thermosensitive coloring layer 21b is made of a material that develops color when scanned with heat from a thermal head of a printer (not shown).

[0020] Rear surface base material 22 constitutes the rear surface of wristband 1. Rear surface base material 22 is embossed, which ensures breathability between the rear surface and the human skin. The embossing also imparts cushioning properties to rear surface base material 22, making it soft to the touch against the skin.

[0021] In this embodiment, the laminate layer 23 is a polyethylene resin. The thermal substrate 21 and the back substrate 22 are heat-sealed by molten polyethylene resin. In addition, any material that is normally used as an adhesive for lamination can be used for the laminate layer 23. As an example, an acrylic, urethane, silicone, rubber, or other adhesive or adhesive can be used.

[0022] Examples of the adhesive that forms the adhesive portion 12 include acrylic, urethane, silicone, and rubber-based adhesives and bonding agents.

[0023] As shown in Figs. 1 and 2, in wristband 1, a breaking notch 13 is formed at end 11a of band portion 11 where adhesive portion 12 is formed.

[0024] As shown in FIG. 3, the breaking slit 13 is a slit penetrating the band portion 11, and is formed at the position of the adhesive portion 12 arranged at the end portion 11a.

[0025] 4 is a perspective view of wristband 1 according to this embodiment. Wristband 1 is used by wrapping it around the wrist and attaching adhesive portion 12 formed on the back surface of end portion 11a to a part of the surface of band portion 11 in a ring shape. Since adhesive portion 12 can be attached to any position on the surface of band portion 11, the ring diameter can be freely adjusted.

[0026] The arrow P shown in Fig. 4 is for illustrating the direction in which the end portion 11a is peeled off. The direction of the arrow P in Fig. 4 corresponds to the direction of the arrow P shown in Fig. 6 described later.

[0027] Next, a description will be given of the breaking notch 13. Fig. 5 is a diagram illustrating one cutting element 30 of the breaking notch 13.

[0028] The incision element 30 is formed by connecting two parallel first line segments 31, 32 and a second line segment 33. The second line segment 33 connects one end 31a and one end 32a of the first line segments 31, 32, and the second line segment 33 is longer than the first line segments 31, 32.

[0029] In addition, in the first line segments 31, 32, ends 31b, 32b opposite to ends 31a, 32a connected by second line segment 33 are bent toward the inside of opening 34 to form bent portions 35, 36.

[0030] In this embodiment, the bent portions 35, 36 and the connecting portion between the first line segments 31, 32 and the second line segment 33 are formed by curved lines. Therefore, when the end portion 11a is peeled off, the tearing in the cutting element 30 tends to progress.

[0031] In this embodiment, the cut element 30 is in the shape of the alphabet "C" in the Agency-FB font.

[0032] In this embodiment, a plurality of the above-mentioned cutting elements 30 are formed radially on the end portion 11a. The cutting elements 30 are formed so that the opening 34 formed by the first line segments 31 and 32 and the second line segment 33 faces the radial center.

[0033] FIG. 6 is a diagram illustrating a plurality of breaking notches 13 formed in the end portion 11a.

[0034] The breaking notches 13 have a plurality of first breaking notches 131 (hereinafter referred to as first breaking notches 131), a plurality of second breaking notches 133 (hereinafter referred to as second notches 133), and a plurality of third breaking notches 135 (hereinafter referred to as third notches 135). In this embodiment, the first breaking notches 131, the second notches 133, and the third notches 135 correspond to the cutting elements 30, respectively.

[0035] In this embodiment, there are first cuts 131a, 131b, 131c, and 131d. In addition, there are second cuts 133a, 133b, 133c, and 133d. In addition, there are third cuts 135a, 135b, 135c, and 135d.

[0036] When the first cuts 131a to 131d are not to be distinguished from one another, they will be referred to as the first cut 131 without using an alphabetical sub-number. The same will be applied in the description of the second cut and other components described later.

[0037] The first indentations 131a, 131b, 131c, and 131d are formed radially. Adjacent first indentations 131 are formed discontinuously. In the radial direction, a second indentation 133 having the same shape as the first indentation 131 is formed on the outside of the first indentation 131 and is discontinuous from the first indentation 131.

[0038] That is, a second cut 133a is formed on the radially outer side of the first cut 131a. A second cut 133b is formed on the radially outer side of the first cut 131b. A second cut 133c is formed on the radially outer side of the first cut 131c. A second cut 133d is formed on the radially outer side of the first cut 131d.

[0039] Further, on the outer side in the radial direction of the discontinuous portion 132 between adjacent first cuts 131 , a third cut 135 that is discontinuous with the first cut 131 and the second cut 133 is formed.

[0040] That is, a third cut 135a is formed on the radially outer side of discontinuous portion 132a. A third cut 135b is formed on the radially outer side of discontinuous portion 132b. A third cut 135c is formed on the radially outer side of discontinuous portion 132c. A third cut 135d is formed on the radially outer side of discontinuous portion 132d.

[0041] In this embodiment, a central notch 136 is formed at the radial center of the breaking notches 13. The opening direction of the central notch 136 is arbitrary. The opening direction of the central notch 136 may be formed so as to be the same as the opening direction of any of the first notch 131, the second notch 133, and the third notch 135, or may be formed so as not to coincide with the opening direction of any of the notches.

[0042] The wristband 1 in this embodiment forms a ring shape with a breaking slit 13 formed in the end 11a, and when the end 11a, which is attached to a part of the surface of the band portion 11, is pulled away from the band portion 11, the breaking slit 13 ruptures and the end 11a breaks.

[0043] As an example, a case where the end portion 11a is peeled off along the direction of the arrow P shown in FIG. 4 and FIG. 6 will be described.

[0044] In this case, the second cuts 133a are split open along the radial direction, and the periphery of the area A defined by the second cuts 133a is peeled off while the area A remains on the surface of the band portion 11.

[0045] In this embodiment, the first cut 131 and the second cut 133 (cut element 30) are formed with bent portions 35, 36 as shown in Fig. 5. Therefore, the width of the portion that remains on the surface of the band portion 11 is narrowed, and the bent portions 35, 36 are easily broken.

[0046] If the second cut 133a is further peeled off after the tearing reaches the end portion of the second cut 133a (bend portions 35, 36), the peeling stress is concentrated in the discontinuous portion between the first cut 131a and the second cut 133a, causing the discontinuous portion to break.

[0047] As the discontinuous portion breaks, the tearing progresses along the first indentation 131a, so that the periphery of the region B separated by the first indentation 131a is torn off while the region B remains on the surface of the band portion 11. This causes the breakage of the end portion 11a at the discontinuous portion to progress.

[0048] Thus, with wristband 1 according to this embodiment, at this point, the history of peeling off end 11a of band portion 11 formed into a ring shape becomes visually clear. Furthermore, after being peeled off, end 11a is no longer in the state it was in before being attached to band portion 11, and so cannot be formed into a ring shape again. Therefore, wristband 1 cannot be reused.

[0049] For this reason, the wristband 1 according to this embodiment can be suitably used in place of an admission ticket at event venues, concerts, and the like.

[0050] 7 is a perspective view illustrating a continuum of wristbands 1 according to this embodiment. As an example, wristband 1 is provided in the form of a rolled continuum R. In the continuum R, perforations 40 for separation are provided at the boundary between wristband 1 and wristband 2.

[0051] The continuous body R is set in a printer (not shown) and printed on the thermal base material 21 of the band portion 11 while being fed in the direction of arrow F in FIG.

[0052] In this embodiment, the continuous body R is formed so that the breaking slit 13 is on the rear side in the payout direction F of the continuous body R, that is, on the upstream side in the conveying direction.

[0053] For example, when a thermal printer is used, the continuous body R is fed out while sliding against the thermal head during printing. In this embodiment, since the first notch 131, the second notch 133, and the third notch 135 are formed with curved portions, when the thermal head slides over the surface of the band portion 11, the thermal head and the breaking notch 13 are unlikely to get caught, and the periphery of the breaking notch 13 is not rolled up during printing.

[0054] [Other embodiments] Although the embodiments of the present invention have been described above, the above-mentioned embodiments merely illustrate some of the application examples of the present invention, and are not intended to limit the technical scope of the present invention to the specific configurations of the above-mentioned embodiments.

[0055] In this embodiment, the wristband 1 shown in FIG. 1 is described as being cut from a roll-shaped continuous body R as shown in FIG. 7, and therefore the four corners of the band portion 11 are shown as being approximately right angles.

[0056] Alternatively, the four corners of band portion 11 may be formed in an arc shape. In this case, this can be achieved by forming perforations to cut out the four corners of wristband 1 in an arc shape. By having the four corners of wristband 1 in an arc shape, it is possible to reduce irritation when the corners come into contact with human skin.

[0057] The wristband 1 according to this embodiment may be compatible with RFID. That is, the wristband 1 may include an RFID inlay configured by connecting an IC chip conforming to RFID specifications to an antenna pattern. The RFID inlay may be laminated between the band base material and the surface base material of the wristband 1, or may be laminated on the outside of the surface base material.

[0058] In this embodiment, the wristband 1 is described in which the thermal substrate 21 and the back substrate 22 are laminated as the band portion 11, but a substrate for thermal transfer printing or a substrate for inkjet printing may be used instead of the thermal substrate 21. Furthermore, the band portion 11 may be a single substrate, in addition to a substrate in which multiple substrates are laminated.

[0059] 8 is a plan view of a label 100 to which the breaking slit 13 according to this embodiment is applied. The breaking slits described as the above-mentioned embodiments and modifications can also be applied to labels that are attached to an adherend. [Explanation of symbols]
