Description

The present invention relates to a wristband.

Wristbands are used in place of admission tickets at events and concerts. They are also used in medical institutions to identify patients and visitors (see Patent Document 1).

JP 2020-38386 A

Wristbands such as those described in Patent Document 1 have a break slit formed in them so that the band breaks when an attempt is made to peel off the attached part, preventing unauthorized use by sharing between users.

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

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 the band portion, so that when the end portion is peeled off from the band portion, it can be securely broken, so that it cannot be reused as a wristband.

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 on one end of the band portion, the adhesive portion being formed into a ring shape by adhering the adhesive portion to a part of the band portion, the end portion having 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 end of the first line segments and being longer than the first line segments, the wristband being formed so that an opening formed by the first line segments and the second line segments faces the radial center.

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 and second line segments faces 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 breaks at the second line segment of the first breaking notches, the tear spreads along the pair of first line segments, and the end breaks 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 the state it had before it was attached, and cannot be formed into a ring shape again.

[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.

In this embodiment, the front surface of the wristband 1 is the surface on which a specific design or text is pre-printed. The back surface of the wristband 1 is the opposite surface to the front surface, which is the surface that comes into contact with human skin.

The 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 the band portion 11.

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. To make the drawing easier to understand, the separator S is not shown in FIG. 1.

As shown in FIG. 3, the thermal substrate 21 is a surface substrate 21a on which a thermosensitive coloring layer 21b is provided. Therefore, the thermal substrate 21 on which the thermosensitive coloring layer 21b is disposed constitutes the surface of the wristband 1.

Materials that can be used for the surface substrate 21a include single resin films such as polyvinyl chloride, polyethylene terephthalate, polypropylene, polyethylene, and polyethylene naphthalate, or multilayer films made by laminating multiple of these resin films.

In addition to the above-mentioned resin film substrates, paper substrates such as cardboard, high-quality paper, medium-quality paper, or coated paper with a coating layer appropriately formed on these can also be used.

In this embodiment, the thickness of the surface substrate 21a can be 10 μm or more and 300 μm or less. When using paper as the surface substrate 21a, the thickness of the surface substrate 21a can be 50 μm or more and 260 μm or less within the above range, and it is usually preferable to use 80 μm.

When a resin film is used as the surface substrate 21a, the thickness is from 25 μm to 200 μm within the above range, and in particular, the surface substrate 21a may have a thickness of 10 μm to 200 μm. These can be selected appropriately depending on the application.

The thermosensitive coloring layer 21b is made of a material that changes color when the thermal head of a printer (not shown) heats and scans the material.

The back substrate 22 constitutes the back surface of the wristband 1. The back substrate 22 is embossed, which ensures breathability between the back substrate 22 and the human skin. The embossing also gives the back substrate 22 cushioning properties, making it soft to the touch against the skin.

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

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

As shown in Figures 1 and 2, the wristband 1 has a breaking notch 13 formed at the end 11a of the band portion 11 where the adhesive portion 12 is formed.

As shown in FIG. 3, the breaking notch 13 is a notch that penetrates the band portion 11 and is formed at the position of the adhesive portion 12 located at the end portion 11a.

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

The arrow P in FIG. 4 is intended to explain 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 in FIG. 6, which will be described later.

Next, we will explain the breaking notch 13. Figure 5 is a diagram explaining one of the cutting elements 30 of the breaking notch 13.

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.

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

In this embodiment, the bends 35, 36 and the connection between the first line segments 31, 32 and the second line segment 33 are formed with curved lines. Therefore, when the end portion 11a is peeled off, the tearing of the cutting element 30 tends to progress.

In this embodiment, the cut element 30 is in the shape of the letter "C" in the Agency-FB font.

In this embodiment, multiple cutting elements 30 as described above are formed radially on the end portion 11a. Furthermore, the cutting elements 30 are formed so that the opening 34 formed by the first line segments 31, 32 and the second line segment 33 faces the radial center.

Figure 6 is a diagram illustrating the multiple breaking notches 13 formed in the end portion 11a.

The breaking notches 13 have a plurality of first breaking notches 131 (hereinafter referred to as first 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 notches 131, the second notches 133, and the third notches 135 each correspond to a cutting element 30.

In this embodiment, there are first cuts 131a, 131b, 131c, and 131d. There are also second cuts 133a, 133b, 133c, and 133d. There are also third cuts 135a, 135b, 135c, and 135d.

When there is no need to distinguish between the first cuts 131a to 131d, they will be referred to as the first cut 131 without using an alphabetical sub-number. This will also be the case in the description of the second cut and other components described below.

The first indentations 131a, 131b, 131c, and 131d are formed radially. Adjacent first indentations 131 are formed discontinuously with each other. In the radial direction, a second indentation 133 of the same shape as the first indentation 131 is formed on the outside of the first indentation 131, and is discontinuous with the first indentation 131.

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.

In addition, a third cut 135 that is discontinuous with the first cut 131 and the second cut 133 is formed on the radially outer side of the discontinuous portion 132 between adjacent first cuts 131.

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.

In addition, in this embodiment, a central notch 136 is formed at the radial center of the breaking notch 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.

The wristband 1 according to this embodiment is in a ring shape with a breaking notch 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 notch 13 ruptures and the end 11a breaks.

As an example, we will explain the case where the end 11a is peeled off in the direction of the arrow P shown in Figures 4 and 6.

In this case, the second cut 133a splits open along the radial direction, and the periphery of area A is torn off while area A defined by the second cut 133a remains on the surface of the band portion 11.

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. This narrows the width of the portion that remains on the surface of the band portion 11, making it easier for the bent portions 35, 36 to break.

If the second cut 133a is further peeled off after the tearing reaches the end portion of the second cut 133a (bends 35, 36), the peeling stress concentrates on the discontinuous portion between the first cut 131a and the second cut 133a, causing the discontinuous portion to break.

As the discontinuous portion breaks, the tearing progresses along the first indentation 131a, so that the periphery of region B, defined 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 11a at the discontinuous portion to progress.

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

For this reason, the wristband 1 according to this embodiment can be ideally used as a substitute for an admission ticket at events, concerts, etc.

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

The continuous body R is set in a printer (not shown) and printed on the thermal substrate 21 of the band portion 11 while being unwound in the direction of arrow F in FIG. 7.

In this embodiment, the continuous body R is formed so that the breaking notch 13 is on the rear side of the payout direction F of the continuous body R, i.e., on the upstream side of the conveying direction.

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, the first notch 131, the second notch 133, and the third notch 135 are formed with curved portions, so that 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 will not roll up during printing.

[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.

In this embodiment, the wristband 1 shown in FIG. 1 is described as being cut from a rolled continuous body R as shown in FIG. 7, so the four corners of the band portion 11 are shown as being approximately right angles.

In contrast, the four corners of the 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 the wristband 1 in an arc shape. By having the four corners of the wristband 1 in an arc shape, it is possible to reduce irritation when they come into contact with human skin.

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 substrate and the surface substrate of the wristband 1, or may be laminated on the outside of the surface substrate.

In this embodiment, the wristband 1 is described as having the thermal substrate 21 and the back substrate 22 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 made of multiple substrates laminated together.

Figure 8 is a plan view of a label 100 to which a breaking slit 13 according to this embodiment is applied. The breaking slits described in the above embodiments and modifications can also be applied to labels that are attached to an adherend.
