Description

  The present invention relates to a wristband separation structure, and in particular, a wristband used for displaying or holding personal information by being loosely wrapped around a limb of a patient or a resident such as a wrist or an ankle in a hospital or an amusement park. It relates to the separation structure.

   Conventionally, identification data unique to the patient, such as the department, name, age, and blood type of the patient, such as a hospital, are printed on a wristband and displayed using a bar code or two-dimensional code if necessary. The patient's identification is ensured by loosely wrapping around the limbs, such as wrists or ankles.

A conventional wristband will be outlined with reference to FIGS.
FIG. 7 is a plan view of a band base material 1 for forming a wrist band. The band base material 1 is composed of a belt-like base material, and the wrist band 3 and the scraping portion are separated by a cutting line 2 for separation. 4 can be separated.

The wristband 3 is provided with a personal information printing area 5 (printing area) capable of printing personal information of the human body on the front surface 3A side, and the back surface 3B is wound around at least one of the extremities of the human body. .
Further, a plurality of set holes 6 and band holes 7 are formed at both ends of the wrist band 3, and after the wrist band 3 is formed into a ring shape, any one of the set holes 6 and the band holes 7 are aligned. For example, it can be fixed and wound by a band clip (not shown).

  As with the personal information printing area 5 on the wristband 3, a caution note is also printed on the scraping portion 4 in order to display the usage of the wristband 3, precautions, explanations, and advertisements. An area 8 (printing area) is provided.

FIG. 8 is a side view of a principal part of a thermal printer 9 for printing in the personal information printing area 5 or the cautionary note printing area 8, and the printing section has a thermal head 10 and a platen roller 11, The thermal transfer ribbon 12 is superposed on the band substrate 1 and printing is performed on the surface 1A side of the band substrate by the thermal transfer method.
For example, in the personal information printing area 5, identification data unique to the individual such as a department, name, age, blood type, etc. is printed using a bar code or a two-dimensional code if necessary. An IC chip capable of communicating data by contact and an RFID inlet 13 (FIG. 7) with a built-in antenna are provided.
In addition, in the caution note print area 8, "Please peel off here", "Print progress direction⇒" and other necessary items are printed.

However, in the manufacturing process of the band base material 1, first, a precautionary printing area 8 is printed on the surface 1 </ b> A of the band base material 1, and die cutting is performed by using a flat or roll-shaped cutting tool. A cutting line 2 is formed, manufactured as a band substrate 1, and wound up.
Next, after the user prints the personal information print area 5 on the surface 3A of the wristband 3 by using the thermal printer 9 (for example, at a hospital), the user removes the wristband 3 and the residue at the cutting line 2 for separation. The part 4 is cut off, and finally the wristband 3 is attached in a ring shape with the back surface 3B side facing the patient's wrist or ankle.

The cutting line 2 for detaching is for punching the wristband 3 from the band base material 1.
FIG. 9 is a cross-sectional explanatory view of the cutting direction for forming the cutting line 2 for separating the band base material 1 (wrist band 3), and FIG. 10 is a schematic cross-sectional view of the wrist band 3 as a result of die cutting, When the band base material 1 is completely removed in the thickness direction, the wrist band 3 is naturally separated from the residue removing portion 4, so the cutting blade 14 is cut with a predetermined cutting depth less than the thickness of the band base material 1. To be processed.
However, the entire cut-out portion 2A (FIG. 7) is formed only at the end of the cutting line 2 for cutting , for example, the semicircular arc-shaped end of the set hole 6, so that the wristband 3 can be separated from the scraping portion 4. A trigger part is created, and “Please peel off here” is printed in advance in the note print area 8.

Conventionally, as shown in FIG. 9, in order to form the cutting line 2 for separation, the cutting blade 14 is moved from the front surface 1A side to the back surface 1B side of the band base material 1 (that is, from top to bottom in the figure). The cutting blade 14 was to be operated.
However, as shown in FIG. 10 in particular, the outer peripheral edge of the band base material 1 (wrist band 3) on the back surface 3B side when the wrist band 3 and the scrap removing part 4 are separated from each other with the part of the cutting line 2 for separation. Since the burr 15 is formed in the portion and this burr 15 protrudes to the back surface 3B side of the wristband 3, there is a problem that it comes into contact with the patient's skin and becomes a stimulus.
The burr 15 is considered as one of the factors of skin inflammation, and it is required to reduce the burr 15 as small and as small as possible.

  The present invention has been considered in view of the above problems, and an object of the present invention is to provide a wristband and a structure for separating the wristband so as not to give unnecessary stimulation to the skin of a patient or a user.

  It is another object of the present invention to provide a wristband and a structure for separating the wristband so that burrs are unlikely to appear on the back surface side that comes into contact with the human body when being separated from the waste removal portion.

  It is another object of the present invention to provide a wristband and its separation structure capable of reducing and reducing the burr as much as possible on the back surface side in contact with the human body at the time of separation.

Moreover, this invention makes it a subject to provide the wristband which made it possible to reduce the direct irritation | stimulation to skin by adjusting the cutting direction and cutting depth of the cutting line for cutting, and its cutting structure.

That is, the present invention is capable of printing the personal information of the human body on the front surface side, and separating the wristband that wraps the back surface of the human body toward at least one of the extremities of the human body from the band-shaped band base material. It is a band base material separation structure that can be formed separately from the scrap removal part at the cutting line, and the band base material comprises a surface layer containing at least polyethylene, a central layer made of nylon, and an embossed layer made of polyethylene, In the printing state, the wristband does not protrude from the embossed layer when the wristband is separated from the wristband substrate while having a strength that does not separate the wristband from the wristband substrate. in, that cuts the disconnect cutting line from the embossed layer to a predetermined depth of the surface layer A disconnecting structure of the band substrate, wherein.

In the wristband and the separation structure thereof according to the present invention, a cutting line for cutting is formed by cutting from the back surface side of the band base material toward the printing surface side, and the cutting depth of the cutting line for cutting into the band base material is formed. Since the thickness is 40% to 75% of the thickness of the band base material, the degree to which burrs are formed on the back side that touches the human body is minimized, direct irritation to the skin is reduced, and long-time wearing is possible. However, the wristband can minimize the adverse effects on the skin.

The present invention, since the 40% to 75% of the thickness of the band base material cut depth to the band substrate disconnect cutting lines forming cuts toward the print surface side from the back side of the band base In addition, a wristband capable of reducing direct irritation to the skin and its separation structure were realized.

Next, a wristband and its separation structure according to an embodiment of the present invention will be described with reference to FIGS. However, the same parts as those in FIGS. 7 to 10 are denoted by the same reference numerals, and detailed description thereof will be omitted.
FIG. 1 is a plan view of the band base material 20, and allows the wristband 22 and the scrap removing portion 23 to be formed by the cutting line 21 for separation.

Figure 2 is a longitudinal sectional view of the band base material 20, the band base material 20 (i.e. the portion of the wristband 22 of the separating cut line 21) includes a central layer substrate 24 by such as nylon, middle layer group An embossed layer base material 25 made of polyethylene or the like on the back side of the material 24 and a surface layer base material 26 made of polyethylene or the like on the surface side of the central layer base material 24 are provided. The embossed layer base material 25 is embossed to facilitate ventilation between the user's skin surface and the back surface 20B of the band base material 20 (the back surface 22B of the wristband 22).
The thickness of the middle layer substrate 24 has a thickness of approximately 50 [mu] m, the embossed layer substrate 25 has a thickness of approximately 50 [mu] m, the surface layer base material 26 is from about 200 [mu] m, the thickness of the entire band base material 20 in this embodiment The thickness is about 300 μm.

FIG. 3 is a cross-sectional explanatory view of the cutting direction for forming the cutting line 21 for separating the band base material 20 (wrist band 22), and FIG. 4 is a schematic cross-sectional view of the wrist band 22 as a result of die cutting. The cutting blade 14 is processed so as to cut at a predetermined cutting depth.
That is, in order to form the wristband 22, the cutting blade 14 is used to move from the back surface 20B side (the back surface 22B side of the wristband 22) of the band base material 20 to the front surface 20A side (the front surface 22A side of the wristband 22). (That is, from the bottom to the top in the figure), the cutting blade 14 is operated.
Note that the cut angle of the cutting line 21 for separation is 40 to 50 degrees.
The cutting depth of the cutting line 21 for separation into the band base material 20 is 40% to 75%, preferably 50% to 60%, more preferably about 57% of the thickness of the band base material 20. It is desirable.
However, a cut- out portion of the wristband 22 from the scraping portion 23 is created by forming a fully-extracted portion 21A only at the end of the cutting line 21 for cutting , for example, the semicircular arc-shaped end of the set hole 6 portion. To do.

As shown in FIG. 4, when the wristband 22 and the scrap removing portion 23 are separated from each other with the cutting line 21 for separation, the outer peripheral edge portion on the back surface 22B side of the band base material 20 (wristband 22) Even if the burr 15 is formed, the burr 15 protrudes to the surface 22A side of the wristband 22, so that it does not come into contact with the patient's skin and cause irritation.
It should be noted that the burr 15 may protrude from the surface 20A of the band base material 20 in the fully-extracted portion 21A, but the thermal transfer ribbon 12 is interposed between the thermal head 10 and the wristband 22. as well as, by suppressing the cutting depth of the band base 20 of the separating cut line 21 to 40% within 75% thickness of the band base material 20, to minimize the impact on the thermal head 10 be able to.

In order to confirm the above-mentioned contents, four types of wristband samples “I”, “B”, “C”, “Two” are prepared, and the back side of the wristband at a temperature of 23 ° C. and a humidity of 50% A rubbing test using 3A (the back surface of the embossed layer base material 25, that is, the embossed surface), and a wristband and residue removal test were performed.
FIG. 5 is a schematic cross-sectional view of the above-described four types of wristband samples “I”, “RO”, “HA”, “II”, and each sample “I”, “RO”, “HA” “Two” has the same material and thickness as the band base material 20 and has the same cut angle.
Sample "b" is a same as conventional band substrate 1, the cutting blade (about 57% of the total thickness) cut depth 170μm from the surface 1A toward the back surface 1B by 14 the separating cutting line up to 2 It is a band base material in which is cut.
Unlike the conventional case, the sample “B” is cut off by the cutting blade 14 from the back surface 20B to the front surface 20A to a depth of cut of 60 μm (about 20% of the total thickness) from the back surface 20B (that is, slightly shallow). This is a band base material obtained by cutting the cutting line 21.
Unlike the conventional case, the sample “C” is separated by the cutting blade 14 from the back surface 20B toward the front surface 20A up to a depth of cut of 240 μm (about 80% of the total thickness) from the back surface 20B (that is, slightly deep). This is a band base material obtained by cutting the cutting line 21.
Sample "two" is the band base material 20 according to the present invention, cutting depth 170 [mu] m (about 57% of the total thickness) the separating cutting line to from the back surface 20B toward the surface 20A from the back 20B by the cutting blade 14 This is a band base material 20 in which 21 is cut.

FIG. 6 is a chart showing the results of a scratch test and a detachment test.
In the rubbing test, the surface (ink surface) of the thermal transfer ribbon 12 is rubbed back and forth 100 times with a constant pressing force on the back side of each sample “I”, “B”, “C”, and “N”. It is a test.
As shown in the figure, it was found that the samples “I” and “B” have many scratches on the thermal transfer ribbon 12 and the samples “C” and “N” have few scratches. As a comparison of the number of scratches, the samples were “b”, “b”, “c”, and “d” in order of increasing scratches.
In the microscopic investigation of each sample, it was possible to confirm the burrs 15 on the back surface side (the surface side in contact with the human body skin). , “I”, “C”, “N”.

  The detachment test is a test for measuring the detachment force (peeling force) from the debris removal portion of the wristband. That is, it represents the weight (g) necessary for separating the wristband or the scraping portion by 15 mm from each other. ”And“ c ”, but there was no significant difference between them.

As shown in FIG. 6, even if the cutting line 20 for cutting is cut from the back surface 20B side to the front surface 20A side of the band base material 20, the depth of the burr 15 is different from that of the burr 15 as in the sample “B”. It was found that there were many occurrences.
Note that if the depth of cut is too deep as in sample “C”, there is a high possibility that the wristband will naturally separate from the residue portion, so it is appropriate to use the depth of cut as in the present invention. is there.
Thus, the wristband 22 capable of reducing the influence of the burr 15 on the patient and other human bodies as much as possible could be created.
