Description

  The present invention relates to a laminated body for a display band and the like. More specifically, it is possible to print individual information on the surface, and it is attached to a wrist, ankle, etc. for personal identification in medical institutions, entertainment facilities, etc. The present invention relates to a display band laminate and a display band having good properties.

  In recent years, display bands have been used to identify individuals in medical institutions, entertainment facilities, and the like. Recently, in particular, in medical institutions, in order to prevent medical accidents, there has been an increasing demand for display bands in which personal identification information is printed and recorded based on inpatient information. However, conventional display bands have not been obtained with a display band laminate that is inexpensive, lightweight, and has good printing runnability.

  Patent Document 1 proposes a wristband having a three-layer structure, but has a large number of parts and a large number of production processes, so that it is expensive in cost and lacks versatility.

Patent Document 2 proposes a wristband using an ethylene methacrylic acid copolymer as a material for a contact surface to the human body, and the ethylene methacrylic acid copolymer contains a carboxyl group in its molecular chain. For this reason, there is a concern of running failure due to adhesion to metal or the like accompanying printing by a printer, which is problematic.

  The present invention provides a display band laminate and a display that are capable of printing individual information on the surface and are attached to wrists, ankles, etc. for personal identification in medical institutions, entertainment facilities, etc. The purpose of the present invention is to obtain a band and the like, and a means for solving such a problem is proposed.

In order to solve the above problems, the present invention has found that the above problems can be solved by adopting an ethylene-methyl methacrylate copolymer having a methyl methacrylate content in a specific range as the back substrate. And completed based on this knowledge.
That is, the present invention
“1. A laminate in which at least a printer-printable display surface base material and a back surface base material in contact with the human body are bonded together, and the back surface base material has an ethylene-methacrylic acid content of 10 to 35% A laminate for a display band, wherein an acid methyl copolymer is used.
2. Indication which uses printer printing as needed on the surface base material of the layered product of 1st term, cuts off an unnecessary part, winds a strip-shaped member around a human body, locks it with a locking means, and uses it band. ".

  According to the display band laminate and the display band, it is possible to print individual information on the surface, and it can be well attached to the wrist, ankle, etc. for personal identification in medical institutions, entertainment facilities, etc. The effect which can obtain the laminated body for display bands etc. with favorable property is show | played. In addition, while having the necessary strength, it has an excellent effect that it can be broken and discarded relatively easily when it becomes unnecessary.

  The laminate for a display band of the present invention is a laminate in which at least a printer-printable display surface substrate and a back substrate in contact with the human body are bonded together, and the back substrate in contact with the human body has a methyl methacrylate content. It is characterized by comprising an ethylene-methyl methacrylate copolymer in a specific range.

  At least a display process substrate capable of printing by a printer and a back surface substrate made of an ethylene-methyl methacrylate copolymer in which the content of methyl methacrylate is in a specific range can be used to produce the manufacturing process. It can be simplified and inexpensive.

  Synthetic paper is suitably used as the display surface base material having printability suitable for printer printing. Synthetic paper includes polypropylene (PP), polyester (PET), and polystyrene (PS) materials, any of which can be used. Specifically, “YUPO (trade name)” (Oji Oil Chemical Co., Ltd.), PP, and the like, which were formed using PP and inorganic fillers as main raw materials while generating microvoids by a biaxially stretched film molding method, Examples include “Peach Coat (trade name)” (Nisshinbo Co., Ltd.), which is based on a film of PET, PS, etc., coated with a white pigment on the surface, and has a porous structure and excellent ink absorbability. Other materials can be used as long as they have printing characteristics and the like, but synthetic paper is optimal from the viewpoints of water resistance and wearability.

  An ethylene-methyl methacrylate copolymer is used for the back substrate. The ethylene-methyl methacrylate copolymer is a suitable material for producing a laminate for a display band that is flexible and has good printer printability. Although the ethylene-methacrylic acid copolymer as described in Patent Document 2 is also a flexible material, since it contains a carboxyl group in its molecular chain, it travels by adhesion to a metal or the like with printing by a printer. There are concerns about defects. On the other hand, since the ethylene-methyl methacrylate copolymer is a methyl ester, there is no fear of running failure due to the influence of polarity such as a carboxyl group, and a flexible and good printing runnability can be obtained. .

  In the production of the laminated body for the display band, the multi-layer structure is bonded while applying a tension in the longitudinal direction. Restoring power is applied. As a result, the obtained laminated body for display band can be curled. According to the curling process, it can be wound around the human body in a natural form, and thus is a preferred form.

  If the back substrate on the side in contact with the human body is configured as a laminate for display band made of a predetermined ethylene-methyl methacrylate copolymer as in the present invention, the curling is performed without special consciousness. This is preferable.

  The display band laminate preferably has an appropriate breaking strength. As the strength of the base material, it is preferable if it is high strength, but when there is no need, there is a need to cut and discard the base material with bare hands. In that case, if the breaking strength is too high, it cannot be cut with bare hands. It becomes a problem.

  Therefore, in the present invention, the content of methyl methacrylate in the ethylene-methyl methacrylate copolymer is set to a specific range. Specifically, the content of methyl methacrylate in the ethylene-methyl methacrylate copolymer is preferably 10 to 35%, more preferably 15 to 25%, and even more preferably 20 to 25%. Increasing the comonomer content, i.e., methyl methacrylate content, increases flexibility, and lowering increases tensile fracture stress. Within this range, the balance between flexibility and strength is good and a more preferable form is obtained.

  Since the ethylene-methyl methacrylate copolymer in this range has a good elongation of the substrate, it can be prevented from being accidentally cut during use. On the other hand, when a stronger force than necessary is applied, it can be broken and removed from the human body. Incidentally, the ethylene-methacrylic acid copolymer as described in Patent Document 2 tends to have high breaking strength because it contains a carboxyl group in its molecular chain, which is convenient for printer printing. When a band is made under conditions such as thickness, it is not easy to break when pulled by normal human force. Is annoying. In addition, regarding the curling, an ethylene-methyl methacrylate copolymer in this range can be expected to be sufficiently stretched and is a preferable form.

  Further, when the thickness of the display surface base material and the back surface base material is 120 μm or less and the total thickness is 250 μm or less, the absolute amount of raw materials can be suppressed and the overall flexibility is improved and the overall weight is also increased. Since it can reduce, it is preferable. In addition, you may give an antibacterial process and embossing to a back surface base material.

  In addition, two or more kinds of materials are integrated using an adhesive when forming a multilayer. It is recommended to use an adhesive that is water resistant and has no effect even if it touches the skin. Although the display band is not directly attached to the human body, it is preferable to use a highly safe one such as a medical adhesive from the viewpoint of safety. In general, acrylic, urethane, rubber, silicon, and vinyl ether adhesives are used as medical adhesives. It is preferable to use a water-resistant adhesive that does not peel off during bathing.

Further, the weight can be reduced even when the display surface base material is a synthetic paper having a density of 1.0 g / cm ³ or less. The most suitable is “YUPO (trade name)” (Oji Oil Chemical Co., Ltd.), which is made of PP and inorganic fillers as main raw materials, and is formed while generating microvoids by a biaxially stretched film molding method.

  The display band laminate has a long shape in which a guide frame is provided on the display band as shown in the drawing so that it can be easily printed by a printer. When using as a display band, after printing necessary information on the printer, cut out unnecessary guide parts, wind a strip-shaped member like the one shown in the figure, and lock it with locking means. To do. In that case, it may be a strip-like member provided with a bulging portion as shown in the figure, or may have a form without a bulging portion. In addition, an appropriate locking tool can be used for locking.

  Next, a display band laminate and a method of using the display band will be described. The display band laminate, which is slit in a strip shape and wound around a branch pipe, is passed through a thermal transfer printing printer to print predetermined items. The printer is preferably capable of inputting specific items such as a patient's name in advance and outputting a barcode or characters in a predetermined format in monochrome or color. In view of the necessity for bathing or the like, it is more preferable if it can perform water-resistant printing.

  After printing, as shown in FIG. 2, the display band 2 is removed from the display band laminate 1, and the hole positions at both ends are aligned so as to surround a part of the human body such as the wrist, and a locking tool (not shown) is used. Lock. At this time, a locking tool may be used, or locking may be performed with an adhesive or the like.

The manufacturing method of the laminated body for display bands is demonstrated. First, the display surface base material 1-1 and the back surface base material 1-3 are bonded to the multilayer structure using the adhesive 1-2 while applying tension in the longitudinal direction. It is preferable to use an embossed material for the back substrate because it feels good and does not stuffy. At this time, a restoring force for each material is applied to the laminate after releasing the tension due to a difference in elongation, and the display band laminate can be curled.
Then, the display band portion is half-cut with a punching blade so as to be easily extracted. Although it does not break at the time of printing, it is important to process it so that it can be easily removed thereafter.
Also in this respect, if the structure of the display band laminate using the above-mentioned predetermined ethylene-methyl methacrylate copolymer is used as the back substrate, the balance between flexibility and strength is good and the object is achieved. Can do.

Examples of the present invention will be described below, but the present invention is not limited thereto.
Example 1
Embodiments of the present invention will be described below with reference to the drawings.
The display surface substrate 1-1 was made of PP and inorganic fillers as main raw materials, and was formed while generating microvoids by a biaxially stretched film molding method. The thickness was 80 μm, the elongation was 106%, and the density was 0.77. (Product Name) "(Oji Oil Chemical Co., Ltd.) is used as the back substrate 1-3, and an antibacterial agent is kneaded with ethylene-methyl methacrylate copolymer pellets having a methyl methacrylate content (MMA content) of 20%. While using an ethylene-methyl methacrylate copolymer film with a thickness of 90 μm and an elongation of 720% formed into a film by extrusion lamination, it was bonded to the multilayer structure using adhesive 1-2 while applying tension in the longitudinal direction. As a result, a laminate for a display band having a total thickness of 225 μm was obtained.
At this time, the back substrate 1-3 used was embossed.
Then, while removing the locking hole, the display band portion 2 was half-cut with a punching blade so that it could be easily pulled out, slitted to form a scroll, and adjusted to a scroll as shown in FIG.

Thereafter, the display band laminate was applied to a thermal transfer printer to print necessary information, and then a half-cut portion was extracted to obtain a display band of the present invention.
The display band was wrapped around the wrist and easily locked with a locking tool, and could be used.
The laminated body for the display band of Example 1 has a good balance between flexibility and strength, can be printed with individual information on the surface, and can be used for personal identification in medical institutions, entertainment facilities, etc., without a sense of incongruity, such as wrists, ankles, etc. It was a laminated body for a display band that was satisfactorily attached to an inexpensive, lightweight, and good print runnability.
In addition, due to the difference in elongation between the front and back materials, the display band laminate is subject to a restoring force for each material on the laminate after the tension is released, and the display band laminate is appropriately curled. I was able to.
Even when the curling process was applied, a predetermined ethylene-methyl methacrylate copolymer film was used as the back substrate 1-3, so that the running stability during printer printing was good.
Further, the half-cut portion did not break at the time of printing, but was suitably processed so that it could be easily removed thereafter.
Further, since it has an appropriate breaking strength, when it is no longer needed, it can be broken by hand and discarded.

Example 2
A display band laminate having a total thickness of 180 μm was completed in the same manner as in Example 1 except that the back substrate 1-3 of Example 1 was changed to one without embossing.

Example 3
A laminate for a display band having a total thickness of 240 μm was obtained in the same manner as in Example 1 except that the back surface substrate 1-3 of Example 1 was an ethylene-methyl methacrylate copolymer film having a thickness of 100 μm. .

Example 4
A display band laminate having a total thickness of 190 μm was completed in the same manner as in Example 3 except that the back substrate 1-3 of Example 3 was changed to one without embossing.

Example 5
A laminated body for a display band having a total thickness of 235 μm in the same manner as in Example 1 except that a peach-coated paper having a thickness of 88 μm, an elongation rate of 100%, and a density of 0.7 was used for the display surface substrate 1-1 of Example 1. Was completed.

Example 6
A laminated body for a display band having a total thickness of 285 μm in the same manner as in Example 1 except that a peach-coated paper having a thickness of 130 μm, an elongation rate of 100% and a density of 1.2 is used for the display surface substrate 1-1 of Example 1. Was completed.

Example 7
The same procedure as in Example 2, except that an ethylene-methyl methacrylate copolymer film having a thickness of 200 μm, an elongation of 750%, and a methyl methacrylate content (MMA content) of 25% was used for the back substrate 1-3 of Example 2. Thus, a laminate for a display band having a total thickness of 290 μm was completed.

Examples 8-11, Comparative Example 1
A display band laminate was completed in the same manner as in Example 1 except that the back substrate 1-3 of Example 1 was changed to the ethylene-methyl methacrylate copolymer film described in Table 1.

  As described above, various evaluations such as printing performance, wearability, and breakability were performed on the display band laminates obtained in the examples.

As described above, all of Examples 1 to 11 were able to obtain good results, and in particular, those of Examples 1 to 5 and Example 8 were able to obtain very good results. .
In Example 6, the surface base material was too thick and heavy, and the wearing feeling was slightly hard.
In Example 7, the back substrate was too thick, and the feeling of wearing was somewhat hard.
The material of Example 9 has poor strength and tends to break without being stretched, and may break during use depending on the application. On the other hand, since it is easy to cut by hand, it can be selected depending on the application to be easily removed.
The thing of Example 10 became a little hard thing, and the wearing feeling was not enough.
On the other hand, since the thing of the comparative example 1 hardly curls, when it winds around a human body, it takes an effort. Moreover, the breaking strength was too strong and could not be easily removed by hand.

  The present invention can be used as a display band for identifying an individual in a medical institution, an amusement facility, or the like. In particular, in medical institutions and the like, it can be effectively used as a display band in which information for personal identification is printed by a printer and recorded based on inpatient information in order to prevent medical accidents.
