Description

  Embodiments of the invention relate to labels.

  For example, a store such as a supermarket that sells fresh food may sell discounts after a certain period of time since the start of the display of fresh food. When a certain period of time has elapsed since the start of the display of fresh food, the store clerk applies a price label indicating a discount to the product one by one.

  Therefore, the work man-hour by the sticking of a price label has taken. In addition, since the clerk decided whether or not to discount the product based on the appearance of the product, the pasting work was affixed with a price tag indicating that the product had sufficient freshness and did not require a discount. In some cases, it is sold without discounts because it is a product that needs to be sold at a discount due to a drop in freshness.

  In this regard, there has been proposed a technique for forming an image on a label using a colorant whose color disappears with time.

  However, even with this technique, it is difficult to carry out discount sales according to the freshness of food.

As shown in FIG. 5, the second image portion 23 is formed with the third color that is substantially the same as the second background portion. Therefore, the second image portion 23 is indistinguishable from the second background portion.

  FIG. 6 is a cross-sectional view of the second display unit 12 after the color has changed. As shown in FIG. 6, the second image portion 23 changes from a third color that is substantially the same as the second background portion to a fourth color that is different from the third color of the second background portion due to a decrease in freshness of the product. .

  Therefore, the second image portion 23 can be identified.

  FIG. 7 is a plan view of the label 1 according to the first application example. As shown in FIG. 7, the label 1 is formed with an image of the third background portion of the first color and substantially the same color as the first color, and is different from the first color by detecting a decrease in freshness of the product. And a third display section 13 having a third image section that changes to the second color.

  The difference between the label 1 according to this application example and the second display portion is that the character portion and the portion around the barcode are not imaged, and the portion around the character portion and the barcode are imaged. It is in.

  FIG. 8 is a plan view of the label 1 according to the first application example after the color has changed. As shown in FIG. 8, the image-formed portion changes to a second color different from the first color of the third background portion, so that the description content, that is, characters and bar codes indicating discount information can be identified. become.

  FIG. 9 is a cross-sectional view of the label 1 according to the first application example before the color changes. As shown in FIG. 9, the third image portion 24 is formed with the first color that is substantially the same as the second background portion. Therefore, the third image portion 24 is indistinguishable from the second background portion.

  FIG. 10 is a cross-sectional view of the label 1 according to the first application example after the color has changed. As shown in FIG. 10, the third image portion 24 changes from the same first color as the third background portion to a second color different from the first color of the third background portion due to a decrease in freshness of the product.

  Accordingly, the third image portion 24 can be identified.

  In this application example, a label for displaying a normal selling price having the configuration of the first display unit 11 of FIG. 1 can be separately bundled with the product.

  In this case, the normal selling price cannot be identified because the color of the first display unit 11 changes as the freshness of the product deteriorates, and the discount price can be identified because the color of the third display unit 13 changes.

  As described above, the label 1 of the present embodiment is formed with an image carrying medium and the first color, and the second color different from the first color is detected by detecting a decrease in freshness of the product. An image portion that changes color and a background portion of the first color or the second color are provided.

  Therefore, there is an effect that discount sales can be performed according to the freshness of the product. Also, when time elapses from processing or display of fresh food, etc., the label changes color according to the freshness, and discount information can be identified. This saves you the trouble of putting a discount sticker on each product. Furthermore, the shopper can purchase at a price according to the freshness of the food, and the freshness of the product can be determined from the display of the label even after the purchase.

  Other colorants include, for example, malachite green, thymol blue, methyl yellow, bromophenol blue, methyl orange, bromocresol green, methyl red, bromocresol purple, bromothymol blue, phenol red, naphtholphthalein, phenolphthalein, Examples include thymolphthalein.

  As the decay detection color material, one or more types are selected from the color material whose color changes according to the pH or the color material whose color changes in response to amine.

(Alkali-soluble material)
As the alkali-soluble material, a material that can be dissolved by an amine generated by the decay of products can be used.

  Examples of the alkali-soluble material include novolak resin, acrylic resin, PVP (polyvinylphenol) resin, epoxy methacrylate resin, isobutylene maleic anhydride copolymer resin, PVA (polyvinyl alcohol) resin, collagen, shellac, and cellulose acetate phthalate. One or more materials selected from the above can be used, but the material is not limited to these.

  Although several embodiments have been described, these embodiments have been presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the equivalents thereof.
