Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lapse display label, and in particular, has a limited effective period of X-ray-sensitive films, photographic papers, photosensitive papers, cosmetics, batteries, oils, chemicals and the like. It is applied to a product or a time-limited entry certificate etc. with anti-counterfeiting, and it is possible to see at a glance whether it is within the valid period (hereinafter referred to as "time indicator" or simply "indicator"). Call).

[0002]

2. Description of the Related Art The following is a method of expressing the period such as the expiration date of a product. For example, in a volatile drug, the active ingredient may be in the form of a solution or wax, and volatilization of these may be visually observed from the outside of the container. This type cannot be applied to all products because the properties of the active ingredient itself are limited to volatile ones. Regardless of the active ingredient, there are indicators that use the volatility of the substance as an indicator of the period, and the degree of coloring decreases due to volatilization of colored liquids (including those absorbed in gel) and volatilization of sublimable dyes. There is something to see. However, the volatilization of substances is greatly affected by temperature and humidity, and it is difficult to show an accurate period, and the volatilized substances may contaminate the surrounding air.

Other examples are light, temperature, humidity, or
A time indicator that can judge the elapsed time is also conceivable by the color change caused by gases such as oxygen (O2) and carbon dioxide (CO2) in the atmosphere.

However, light, temperature, humidity, and the like change greatly in daily life, and therefore a time indicator using them changes color before the scheduled period elapses, or the scheduled period is exceeded. It may be difficult to obtain a stable time indicator because the color may not change even after a certain period of time. In addition, a bag made of a plastic film having a certain amount of oxygen permeability is filled with a colorant, such as methylene blue, which changes its color depending on the amount of O2 in the atmosphere, sealed in a vacuum state, and permeated the plastic film with time. A method was also studied in which the colorant was discolored by O2 that invaded by the ash and the elapsed time was measured. However, the oxygen permeation amount of a plastic film generally changes depending on the ambient temperature and humidity. Stable time that can always measure the passage of a fixed period
Getting an indicator is difficult.

Furthermore, by using CO2 instead of O2,
A bag made of a plastic film having a certain amount of carbon dioxide gas permeability is filled with a colorant that changes its color depending on the change of the pH of the atmosphere, and the bag is sealed in a vacuum state. There is also a method of changing the color of the colorant by changing the color, but this time indicator can not display the effective period of fragrance, deodorant, insect repellent, etc. It has the drawback of discoloring over time (several hours to several tens of hours) and is sensitive to the effects of humidity, so it cannot be used as an indicator to indicate the elapsed time in such applications.

In order to solve such a problem, the applicant of the present invention has disclosed, in Japanese Patent Application No. 4-185027, a dye on a time-lapse label obtained by coating a concealing and dye-diffusing layer on a transparent protective film. By laminating the image receiving sheet on which the printing layer is printed, the dye in the dye printing layer is diffused into the concealing and dye diffusion layers, and the period of several minutes to several months is elapsed, and light humidity and other atmosphere We proposed a time-lapse display that can be displayed in a stable state without being affected by factors inside.

Further, as Japanese Patent Application No. 4-189480,
A hiding layer and a dye diffusion layer are sequentially laminated on a transparent protective film, the laminated dye diffusion layer and the dye printing layer printed on the image-receiving sheet are bonded together, and the dye in the dye printing layer is By diffusing into the dye diffusion layer and the concealing layer, a time-lapse indicator which can display a predetermined period of time in a stable state as described above was proposed.

[0008]

However, the following problems still remain in the time-lapse display body having the above-mentioned configuration.

That is, in this type of time-lapse indicator, a transparent protective film coated with a hiding and dye diffusion layer and an image receiving sheet on which a dye printing layer is printed are separately handed to the user and used. A person can appropriately use an adhesive means or peel off the release sheet provided on the transparent protective film to expose the adhesive layer applied on the upper part of the concealing and dye-diffusing layer in advance to conceal it on the transparent protective film. Also, the dye diffusion layer and the dye printing layer on the image receiving sheet are positioned so that they are aligned with each other, and both are used by bonding.

However, since printing is performed on the surface of the transparent protective film facing the hiding and dye-diffusing layer, or between the transparent protective film and the hiding and dye-diffusing layer,
There is no difference in appearance whether or not the image-receiving sheet having the dye-printed layer printed thereon is bonded to the protective film coated with the concealing and diffusing layer, or not. Therefore, for example, there is a problem that it is possible to perform a forgery in which an image receiving sheet having no dye printing layer is stuck and the elapsed time is not displayed, or the image receiving sheet is not stuck.

The present invention has been made in view of the above circumstances, and forgery is performed such that a protective film coated with a concealing and diffusing layer is laminated with a material different from a regular image-receiving sheet to prevent the passage of time and the like. The purpose of the present invention is to provide a time-lapse indicator that cannot be used.

[0012]

In order to achieve the above object, in the invention described in claim 1, a hiding and dye diffusion layer coated on a transparent protective film, and a dye printing printed on an image receiving sheet. A layer, the dye in the dye-printed layer is a time-lapse indicator that indicates the time lapse by diffusing into the hiding and dye-diffusing layer, and the transparent protective film and the hiding and dye-diffusing layer. And / or a first printing layer is provided on the surface of the transparent protective film opposite to the surface facing the hiding and dye-diffusing layer, and is combined with the first printing layer on the image-receiving sheet. And a second print layer for forming a predetermined image is provided, and a portion of the hiding and dye diffusion layer corresponding to the second print layer is removed.

According to the second aspect of the present invention, the hiding and dye diffusion layer coated on the transparent protective film and the dye printing layer printed on the image-receiving sheet are bonded together, and the inside of the dye printing layer is formed. In a time-lapse display for displaying a time-lapse by the dye being diffused in the hiding and dye-diffusing layer,
A first printing layer is provided between the transparent protective film and the masking and dye-diffusing layer, and / or on the surface of the transparent protective film opposite to the surface facing the masking and dye-diffusing layer, and A removal portion is provided in the masking and dye diffusion layer, and the predetermined image is formed by combining the first printing layer and the dye printing layer portion displayed through the removal portion of the masking and dye diffusion layer. It has been configured.

Further, in the invention described in claim 3, in the invention described in claim 1 or 2, the concealing and dye-diffusing layer is formed separately from the concealing layer and the dye-diffusing layer.

[0015]

The predetermined image can be obtained only by combining the first printing layer and the second printing layer, or the first printing layer and the lower dye printing layer displayed through the removed portion of the hiding and dye diffusion layer. Therefore, if the regular image-receiving sheet on which the dye printing layer is printed is not attached to the protective film coated with the hiding and dye diffusion layer, the above-mentioned predetermined image will not be formed. Immediately and for everyone, it can be seen that the predetermined image receiving sheet is not attached.
