Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a time-lapse label, and particularly to a product having a limited effective period such as a film or photographic paper or photosensitive paper, cosmetics, batteries, oils, chemicals, etc., which are sensitive to X-rays, or anti-counterfeiting. The present invention relates to a time-lapse indicator (hereinafter referred to as "time indicator" or simply "indicator") that can be applied to a time-limited entry certificate, etc., and can tell at a glance whether it is within its valid period.

[0002]

[Prior art]

 There are the following methods for 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 those that are volatile. 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, making it difficult to indicate the exact period, and the volatilized substances may pollute the surrounding air.

As another example, a time indicator that can determine the elapsed time by light, temperature, humidity, or a color change due to a gas such as oxygen (O 2) or carbon dioxide (CO 2) in the atmosphere can be considered.

However, light, temperature, humidity, and the like change greatly in daily life, and therefore a time indicator using these causes color change before the scheduled period elapses, or changes in the scheduled period. It may be difficult to obtain a stable time indicator because the color may not change even after passing. In addition, a colorant that changes its color depending on the amount of O 2 in the atmosphere, such as methylene blue, is placed in a bag made of a plastic film having a certain amount of oxygen permeability, sealed in a vacuum state, and the plastic film is aged with time. A method was also studied in which the colorant was discolored by O2 penetrating and penetrating the colorant, and the elapsed time was measured. However, in general, the oxygen permeation amount of a plastic film changes depending on the ambient temperature and humidity. Therefore, it is difficult to obtain a stable time indicator that can always measure the passage of a certain period.

Further, 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 coloring agent that changes its color depending on the change of pH of the atmosphere, and the bag is sealed in a vacuum state. However, there is also a method of changing the color of the colorant by changing the pH of the atmosphere due to CO 2 which penetrates through this plastic film, but this time indicator is used for the effective period of fragrance, deodorant, or insect repellent. In other words, it has the drawback that it cannot display the period of several months to several years and changes color in a shorter time (several hours to several tens of hours), and it is more sensitive to humidity. In some applications, it cannot be used as an indicator to show the passage of time.

Therefore, as a solution to such a problem, the applicant of the present invention has disclosed, in Japanese Patent Application No. 4-185027, a time-lapse label in which a hiding and dye diffusion layer is applied on a transparent protective film. , The dye-printed layer is printed on the image-receiving sheet, and the dye in the dye-printed layer diffuses into the hiding and dye-diffusing layer, so that the light-humidity We proposed a time-lapse indicator that can be displayed in a stable state without being affected by other atmospheric factors.

Further, as Japanese Patent Application No. 4-189480, a concealing layer and a dye diffusion layer are sequentially laminated on a transparent protective film, and the dye diffusion layer and the dye printing printed on an image receiving sheet are laminated. By adhering the layers together, the dye in the dye-printed layer diffuses into the dye diffusion layer and the masking layer to propose a time-lapse indicator capable of displaying a predetermined period of time in a stable state as described above. .

[0008]

[Problems to be solved by the device]

 However, the following problems remain in any of the elapsed-period display bodies having the above-described configurations.

That is, in this type of time-lapse display body, a transparent protective film coated with a concealing and dye diffusion layer and an image receiving sheet on which the dye printing layer is printed are separately handed to the user. The transparent protective film may be prepared by the user using an appropriate adhesive means or by peeling off the release sheet provided on the transparent protective film to expose the adhesive layer previously coated on the hiding and dye diffusion layers. The concealing and dye diffusion layer on the top 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 being laminated.

However, since there is no guideline for positioning between the transparent protective film and the image receiving sheet, the hiding and the dye diffusion layer and the dye printing layer on the image receiving sheet are positioned. It's very difficult, and there is a problem that they are stuck together and stuck together. In addition, when the two are offset and bonded together in this way, part of the adhesive layer is exposed, and the period indicator is inadvertently adhered to the inner surface of the pocket of clothes or the cover of a book. It is inconvenient to handle. In addition, when a transparent printed pattern on the protective film side and a pattern on the image receiving sheet side are combined to form a predetermined pattern that has a certain meaning, the patterns may be offset or pasted in the wrong direction. When attached, the predetermined pattern is not formed.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a time-lapse display body capable of bonding the transparent protective film side and the image receiving sheet side in a correctly positioned state. To do.

A label having a structure in which the concealing and dye diffusion layers 2 and the like are laminated on the transparent protective sheet 1 having the above-described structure is manufactured as follows. That is, first, the hiding and dye diffusion layer composition is made into a paint with an appropriate solvent, and the paint is applied onto the transparent protective film 1 with a coating applicator such as a gravure coater, a roll coater, a bar coater, a reverse coater, a comma coater, and a die coater. dry. Next, each of the adhesive layer compositions is formed into a paint and applied, and at the same time, the release sheet 4 is attached. The method for coating the adhesive layer composition and the coating method are the same as those for the hiding and diffusion layer composition. Further, the image receiving sheet 5 on which the dye printing layer 6 is printed is also produced in the same manner.

On the other hand, as the image receiving sheet 5, a sheet such as the protective film 1 is used in addition to a normal printing sheet. In this embodiment, the transparent protective film 1 extends and is formed integrally with it.

In this way, the concealing and dye diffusion layer 2 and the like on the transparent protective film 1 and the dye printing layer 6 on the image receiving sheet 5 can be attached in a precisely aligned state as desired, so that the adhesive layer Part of No. 3 is not exposed. For example, even when the period elapsed indicator is stored in a pocket of clothes or the like, a problem such as inadvertently adhering to the inner surface of the pocket or the cover of a book may occur. It can be prevented. Further, even when the printed pattern on the transparent protective film 1 side and the pattern on the image receiving sheet 5 side are combined to form a predetermined pattern having a certain meaning, those patterns can be accurately displayed.

Second Embodiment FIG. 3 shows a second embodiment of the period elapsed display body according to the present invention, and is an enlarged front view of a main part. The same components as those of the first embodiment described above are designated by the same reference numerals and the description thereof will be omitted.

This embodiment is different from the first embodiment in that the transparent protective film 1 and the image receiving sheet 5 are constituted by separate members. That is, the transparent protective film 1 is extended to one side to form the projecting portion 1a, while the image receiving sheet 5 side is also provided with the projecting portion 5a. The projecting portions 1a and 5a are overlapped with each other and joined by an adhesive to form the connecting surface portion 7, and a bent portion 8 is formed on the transparent protecting film 1 side of the connecting surface portion 7. .

Even with such a configuration, as in the first embodiment described above, the masking and dye diffusion layer 2 on the transparent protective film 1 and the dye printing layer 6 on the image receiving sheet 5 are aligned as desired. The effect that it can be pasted in the state is obtained. Further, in this embodiment, the label on the transparent protective film 1 side and the label on the image receiving sheet 5 side can be formed separately, and the advantage that the degree of freedom of production increases can be obtained.

Although the bent portion 8 is formed on the transparent protective film 1 side of the connection surface portion 7 in this embodiment, the invention is not limited to this, and the image receiving sheet 5 side is longer than the transparent protective film 1. Therefore, the bent portion 8 may be formed on the image receiving sheet 5 side, and not only the transparent protective film 1 and the image receiving sheet 5 are made of different members, but the connecting surface portion 7 is also made of a member different from them. However, a structure may be employed in which the bent portion 8 is formed on the connection surface portion 7.

In each of the above examples, the masking and dye-diffusing layer 2 is applied to the transparent protective film 1, but the present invention is not limited to this, and the masking layer and the dye are provided on the transparent protective film 1. A diffusion layer and a concealing layer are sequentially laminated so that the concealing layer is located on the protective film 1 side, and the dye diffusion layer and the dye printing layer printed on the image-receiving sheet 5 are laminated together by way of an adhesive layer. You may make it the structure laminated together.

In addition, in each of the above-described embodiments, the adhesive layer 3 and the release sheet 4 are provided on the transparent protective film 1 in addition to the concealment and dye diffusion layer 2, but the transparent protective film 1 is not limited to this. Only the hiding and dye-diffusing layer 2 or only the hiding layer and the dye-diffusing layer is provided on the film 1, and when the user hands it, the dye on the dye-diffusing layer or the image-receiving sheet 5 on the protective film 1 is provided. An adhesive may be applied on the printed layer 6 so that both are attached.
