JPH04306692A - Commodity label - Google Patents

Abstract

PURPOSE:To easily discriminate a valueless commodity that has not been cooled sufficiently due to operation error, management error, or by being left by a customer, from a normal commodity so as not to sell the valueless commodity by means of a commodity label attached to a commodity such as fresh food, frozen or refrigerated food. CONSTITUTION:By providing a color changing part 2 by which a different display is indicated from an initial display once the temperature of a commodity exceeds a threshold determined for each commodity, on a commodity label 1 attached to the commodity a worker in a shop or a customer can visually judge whether the commodity is good, and the sales of a valueless commodity is inhibited, and the commodity is withdrawn. By providing a barcode display whose display is turned into blank or is merged into the background color once the temperature thereof exceeds a predetermined threshold level, a register does not work for the commodity and the withdrawal of the valueless commodity is ensured independent of visual verification.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to display labels attached to fresh foods, frozen/refrigerated foods, and the like.

0002

BACKGROUND OF THE INVENTION Temperature control is extremely important for stores and transport companies that handle fresh foods or frozen/refrigerated foods. Products such as perishables may be damaged due to operational errors or management errors in the freezer or refrigerator, or customers who take out the products from the refrigerator or freezer and leave them unattended without returning them to the original freezer or refrigerator. The product value may be lost due to the inability to keep the product cold.

[0003] Conventional product labels did not change color or pattern depending on temperature.

0004

[Problem to be solved by the invention] With conventional product labels, it is not possible to distinguish between normal products and products such as fresh foods that have lost their value due to temperature rise, so it is difficult to sell products that have lost their value to customers. This has the problem of not only making customers feel uncomfortable and distrustful, but also causing food poisoning.

[0005] The present invention solves the above-mentioned conventional problems, and prevents the sale of products that have lost their value once the threshold temperature determined for each product has been exceeded. The aim is to provide product labels that do not arouse suspicion or distrust.

[0006]

[Means for Solving the Problems] To achieve this object, the product level of the present invention provides a discolored area or an unreadable display that becomes different from the initial display once the temperature exceeds a predetermined threshold temperature. It has a configuration with a bar code.

[0007]

[Operation] With this configuration, products that cannot be kept cold and have lost their value can be distinguished from normal products by different displays, making it possible to collect them.

[0008] Furthermore, it becomes impossible to read the bar code.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a product label 1 affixed to a product is provided with a discoloration area 2 that displays a different color when the temperature rises and exceeds a predetermined threshold temperature. In this embodiment, the threshold temperature is 10 degrees Celsius.

[0011] Hereinafter, changes in the display of the discolored area 2 of the product label 1 will be explained using FIG. 2. At time t1, when the temperature exceeds the threshold temperature 3 of 10°C, the discolored area 2 changes from the initial display 5 (blank) to display 6 (for example, "Not kept cold, this is a collected item"). Become. That is, the display changes from display 5 to display 6 after time t1. At time t2, the temperature drops again, but
Display 6 remains unchanged. That is, once the temperature rises above the threshold temperature 3, a display different from the initial display will be maintained and a warning will continue to be issued.

As described above, according to the present embodiment, the product label 1 provided with the discolored area 2 that displays a different display from the initial display when the temperature rises and exceeds a predetermined threshold temperature is used for labeling fresh foods, etc. By pasting it on products, if products such as fresh foods cannot be kept cold for some reason and lose their value, they can be easily distinguished from normal food, preventing the sale of products that have lost their value. Can be easily recovered.

Note that in the first embodiment, the display 6 does not change at time t2, but the display 6 may change at time t2 to a display that can be distinguished from the initial display 5 before time t1. Needless to say.

A second embodiment of the present invention will be described below. As shown in FIG. 3, a barcode display 8 is provided on the product label 7, but when the temperature rises and exceeds a predetermined threshold temperature, the barcode display 8 disappears as shown in FIG. This results in a blank space 9 or a display 10 that blends in with the surrounding color. This makes it impossible for a barcode reader to read the product, making it impossible for the register to operate, making it possible to reliably collect products that have lost value without having to rely on visual recognition.

[0015]

[Effects of the Invention] As is clear from the description of the embodiments above, the present invention is capable of discoloring areas where the display becomes different from the initial display or becomes unreadable once the temperature exceeds a predetermined threshold temperature. This product has the advantage of preventing the sale of products that have lost their value by exceeding the threshold temperature determined for each product, ensuring that they can be collected, and preventing customers from feeling uncomfortable or distrustful. This makes it possible to create product labels that are easy to use.

Claims (2)

[Claims] Claims: 1. A product label having a discolored area that becomes a different display from the initial display when the temperature rises above a predetermined threshold temperature and does not return to the initial display. 2. A product label with a barcode display that disappears to a blank or blends in with the surrounding color when the temperature rises above a predetermined threshold temperature.
