It is a top view of the wristband 1 by the Example of this invention. It is the II-II line expanded sectional view of FIG. FIG. 3 is an enlarged back view of the embossed material 15. FIG. 4 is an enlarged explanatory view showing the correlation between the spherical portion 22 of the embossed portion 21 in the embossed material 15 and the triangular triad 23 of the skin in the wound portion. It is a schematic side view of the wristband manufacturing apparatus 30 for manufacturing the wristband 1 (the wristband continuum 1A).

    In the present invention, the band base material is constituted by adopting the laminated material made of the first water- and oil-resistant material, the flexible material and the second water- and oil-resistant material, and the tear-resistant or tensile-resistant core material. A wristband having various necessary characteristics and a method for manufacturing the wristband have been realized.

Next, a wristband and a manufacturing method thereof according to an embodiment of the present invention will be described with reference to FIGS.
1 is a plan view of the wristband 1 and FIG. 2 is an enlarged cross-sectional view taken along the line II-II of FIG. 1. The wristband 1 can display specific information on the surface of the band-shaped band base material 2. At the same time, it can be wrapped around a wound portion (not shown) such as a wrist or an ankle of an inpatient.

The band base material 2 is formed with an elongated annular die cut notch 3 so that the single base wrist band 1 can be punched from the band base material 2.
Further, a plurality of wristbands 1 are continuously connected through a separation cut 4 such as a perforation to form a belt-like wristband continuous body 1A.
In addition, on one arcuate end 1B (the left end in FIG. 1) of the wristband 1, a die-cutting instruction 5 such as “please peel from here” or “printing direction →” is printed in advance. In the arc-shaped end portion 1B, the band base material 2 is penetrated from the front surface to the back surface to form a die-cutting through cut 3A, and the other portion of the die-cutting cut 3 is a die-cutting semi-cut cut 3B (see FIG. 2). ).
Therefore, it is possible to solve the problem of inadvertent peeling when loaded or printed on a predetermined printer (for example, a thermal transfer printer, not shown) when not in use and can be easily peeled off during use. ing.

The wristband 1 has a print region 6 disposed in the center in the length direction, and a first winding portion 7 and a second winding portion 8 are formed on the left and right sides of the print region 6.
A necessary number of mounting holes 9 (two in the illustrated example) are formed in the first winding part 7, and a plurality of selection holes 10 (in the illustrated example) are formed in the second winding part 8. Then, the wristband 1 can be attached so that the attachment hole 9 and the selection hole 10 are fixed by a predetermined fixing clip 11 and wound around the portion to be wound.
Note that a position detection mark 12 is printed in advance on the back surface of the wristband 1 so that the position of the wristband 1 can be detected when it is loaded into the printer for transfer printing.

    In particular, as shown in FIG. 2, the band base material 2 includes a surface base material 13, a core material 14, and an embossing material 15.

The surface base material 13 is composed of a laminated material 19 in which a first water and oil resistant material 16, a flexible material 17 and a second water and oil resistant material 18 are laminated.
As the first water and oil resistant material 16, for example, polypropylene (PP) subjected to corona treatment is employed.
As the flexible material 17, for example, an ethylene vinyl acetate copolymer (EVA) is employed.
For example, polypropylene (PP) is used as the second water / oil resistant material 18.
In addition, the specific information can be printed on the surface side of the surface base material 13 and the surface treatment 20 is applied so that the print information can have permanent durability.

The surface treatment 20 performs a predetermined coating according to the type and characteristics of the ink or ink ribbon used in the predetermined printer. Examples of the surface treatment agent include polyester-based, polyurethane-based, epoxy-based acrylic resins, and the like. The surface treatment agent, or the varnish for printing ink, the medium agent and the like can be used.
In order to improve the reading effect of barcodes and prints, it is desirable to add a pigment such as titanium oxide to form a white background and to adjust the white density (PSC value) to 75 or more.

    The core material 14 has tear resistance or tensile resistance laminated on the lower layer side of the surface base material 13 and is, for example, a soft and strong material such as nylon, polyethylene terephthalate (PET), polypropylene (PP ), A general-purpose film base material such as polyethylene (PE) can be employed, and this is preferably composed of stretched nylon (biaxially stretched nylon).

The embossed material 15 is an embossed film made of, for example, polyethylene that is laminated on the lower layer side of the core material 14, and its back surface is a portion that directly contacts the skin surface such as a patient's wrist or ankle, and is between the skin. An embossed pattern (embossed portion 21) having various uneven shapes for drying sweat and moisture by ensuring air permeability is formed by extrusion molding by an arbitrary method.
The embossed pattern by the embossed portion 21 has a circular or elliptical cross-sectional shape so as to ensure air permeability and minimize skin irritation.
In order to maintain the cleanliness of the skin surface, an inorganic or zinc oxide antibacterial agent is kneaded, but it is necessary to select an antibacterial agent that is as safe as possible in order to directly contact the skin.
In addition, additives such as antioxidants and lubricants may be added in the production of polyethylene. In consideration of the possibility of allergy to the wristband 1 user, an additive-free type polyethylene is desirable.

FIG. 3 is an enlarged back view of the embossed material 15, and FIG. 4 is an enlarged explanatory view showing the correlation between the spherical portion 22 of the embossed portion 21 of the embossed material 15 and the skin triangulated skin 23 of the wound portion. .
That is, the embossed portion 21 has a spherical portion 22 having a circular or elliptical cross-sectional shape. The spherical portion 22 is a triangular shape of the skin when it comes into contact with the skin in the wound portion with a predetermined pressure. Since it has a larger shape than the cuticle 23 (see the hatched portion in FIG. 4), the embossed portion 21 avoids directly stimulating the skin groove 23A between the triangular cuticle 23 across the skin, The skin irritation at the time of wearing can be reduced.
If the embossed portion 21 is too large (too wide), the head pressure during printing on the wristband 1 by the printer will affect the printing on the surface portion (surface treatment 20 portion). The size and pitch of the embossed portion 21 must be limited to about 300 to 1500 μm, including the case where the spherical portion 22 is circular or elliptical.
For example, as the size of the spherical portion 22 of the embossed material 15, when the cross-sectional shape is an ellipse, the short-axis length at the cross-sectional base portion is about 300 μm and the long-axis length is about 500 μm. The length of the interval (concave portion) is preferably about 50 to 300 μm.

    Returning to FIG. 2, the second water and oil resistant material 18 of the laminated material 19 and the core material 14 are bonded to each other via a first adhesive layer 24 made of polyethylene or the like, and the core material 14 and the embossed material 15 are bonded. Are bonded via a second adhesive layer 25 made of polyethylene or the like.

Surface treatment 20, surface substrate 13 (laminated material 19: first water / oil resistant material 16, flexible material 17, second water / oil resistant material 18), first adhesive layer in wristband 1 (band substrate 2) Each thickness of 24, the core material 14, the 2nd contact bonding layer 25, and the embossing material 15 is as follows. However, a tolerance of about ± 10% is allowed for each value.
Surface treatment 20: 1 to 10 μm (for example, 5 μm),
Surface base material 13 (laminated material 19): 100 to 200 μm (for example, 150 μm),
1st water and oil resistant material 16: 10-20 micrometers (for example, 15 micrometers),
Soft material 17: 80-160 μm (for example, 120 μm),
Second water and oil resistant material 18: 10 to 20 μm (for example, 15 μm),
First adhesive layer 24: 10 to 20 μm (for example, 15 μm),
Core material 14: 15-50 μm (for example, 25 μm),
Second adhesive layer 25: 10 to 20 μm (for example, 15 μm),
Embossed material 15: 100 to 160 μm (for example, 130 μm),
Total thickness of wristband 1: 250-445 μm (for example, 300-340 μm).
In addition, the laminated material 19 of the surface base material 13 has a ratio of the laminated thickness of the first water and oil resistant material 16, the flexible material 17 and the second water and oil resistant material 18 to 0.5 to 2: 6 to 9: 0. .5-2 (for example, about 1: 8: 1).

Further, the wristband 1 (band base material 2) has an overall specific gravity of less than 1 by appropriately adjusting the thickness and material of the surface base material 13 and the core material 14.
By setting the specific gravity of the entire wristband 1 to less than 1, the wristband 1 can be manufactured so lightly that it floats on water, and a light feeling that forgets that the wristband 1 is worn can be imparted.
Surface base material 13 (laminated material 19: first water and oil resistant material 16, flexible material 17, second water and oil resistant material 18), first adhesive layer 24, core material 14, and second adhesion in wristband 1 The specific gravity of the resin employed as the material for the layer 25 and the embossed material 15 is, for example, as follows.
Polypropylene (PP): 0.90 to 0.91,
Ethylene vinyl acetate copolymer (EVA): 0.92-0.94,
Polyethylene (PE): 0.92-0.97,
Nylon: 1.02-1.14.
The specific gravity of nylon exceeds 1, but the ratio of the thickness to the total thickness of the wristband 1 is small. Therefore, the thickness of each layer is appropriately designed so that the specific gravity of the entire wristband 1 is less than 1. Can be suppressed.

In addition, when a hospitalized patient receives treatment in a hyperbaric oxygen treatment room, there is a risk of short sparks due to static electricity generated from friction between clothes and the wristband 1, and in order to prevent this, the above-described surface treatment 20, It is desirable to apply or knead an antistatic agent to at least one of the laminated material 19 (first water / oil resistant material 16, flexible material 17, second water / oil resistant material 18), core material 14 and embossed material 15. Thus, even when the wristband 1 is worn, static electricity can be prevented by the antistatic agent, and treatment in the high-pressure oxygen treatment room can be safely received.
As antistatic material, conductive carbon black, graphite, metal oxide or surfactant-based conductive material dispersed in vinyl chloride, vinyl acetate copolymer, acrylic, urethane or polyamide-based resin is used. can do.

    The wristband 1 (the wristband continuous body 1A) as described above can be manufactured by bonding each layer by an extrusion lamination method or a dry lamination method.

    FIG. 5 is a schematic side view of a wristband manufacturing apparatus 30 for manufacturing the wristband 1 (a wristband continuous body 1A). The wristband manufacturing apparatus 30 includes an embossed material forming apparatus 31 and a laminated material laminating apparatus. 32 and a wristband laminating apparatus 33.

    The embossing material forming apparatus 31 obtains the embossing material 15 by extruding the film material of the embossing material 15 with a pair of extrusion forming rolls 34 so as to form the embossed portion 21 on the back surface side.

    The laminated material laminating apparatus 32 obtains the laminated material 19 by laminating the first water and oil resistant material 16, the flexible material 17 and the second water and oil resistant material 18 by the laminating roll 35.

In the wristband laminating apparatus 33, the material of the first adhesive layer 24 is supplied from the first adhesive supply tank 36 to bond the embossed material 15 and the core material 14, and further the second adhesive supply tank 37. Then, the material of the second adhesive layer 25 is supplied to bond the laminated material 19 to the upper layer of the core material 14.
Further, the surface treatment device 38 performs the surface treatment 20, and the printing device 39 preliminarily prints the mold removal instruction 5, “Remove from here”, “Print direction →”, the position detection mark 12, and the like. The forming device 40 forms the die-cutting cut 3 and the separation cut 4 to produce a belt-shaped wristband continuous body 1A capable of die-cutting the single wristband 1.

    Thus, even when worn for a long time on the wrist or ankle of a hospitalized patient or the like, it is possible to manufacture a wristband 1 that is light, soft, and has the necessary toughness. Resistant printing is possible, and even if a long-term inpatient is attached and used, there is no sense of incongruity, there is almost no feeling of wearing, the product shape does not change to the end, and patient information A completely readable state can be maintained without disappearing.
