Description

Technical Field

[0001] This utility model relates to the field of fresh food hang tag technology, specifically a fresh food hang tag price label. Background Technology

[0002] Currently, supermarkets and fresh food e-commerce platforms generally use disposable paper or plastic price tags, which are only used to display static information such as prices and barcodes, and cannot provide visual indications of whether the product has been subjected to excessive temperatures. If monitoring the cold chain is required, additional temperature labels must be affixed, which is costly and prone to falling off. Some high-end labels attempt to print time-temperature color-changing ink on the back, but in the high-humidity refrigerated environment, condensation randomly accumulates on the label surface, resulting in: inconsistent color change start times, localized ink washing away, and warping of the paper substrate after absorbing water, affecting the reliability of hanging. Therefore, a fresh food price tag is needed to improve upon these issues. Utility Model Content

[0003] The purpose of this utility model is to provide a price tag for fresh produce to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fresh food hang tag, including a hang tag body, a semi-circular hanging hole on the top of the hang tag body, a horizontal information column on the front of the hang tag body, and the hang tag body is a three-layer composite structure formed by hot pressing an outer layer, a middle layer and an inner layer in sequence, wherein the outer layer is a weather-resistant film layer for printing information, the middle layer is a microporous breathable layer, and the inner layer is a cold chain indicator layer.

[0005] As a preferred embodiment of this utility model, the horizontal information column is printed with color-changing ink, and the color-changing ink undergoes an irreversible color change after the change.

[0006] As a preferred embodiment of this utility model, the graphic information printed in the horizontal information column covers the outer surface and is offset from the color-changing area.

[0007] As a preferred embodiment of this utility model, the upper part of the inner layer is provided with a condensate zone, and the lower part is provided with a guide groove that communicates with the condensate zone.

[0008] As a preferred embodiment of this utility model, the guide channel is coated with a food-grade hydrophilic coating.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the synergy of adding color-changing ink to the inner layer and adding flow-guiding micro-grooves to the condensate area, allows the tag to automatically undergo an irreversible color change upon exposure. Consumers can visually determine whether fresh produce has experienced overheating without scanning the code or opening the bag, significantly reducing the food safety risks caused by cold chain disruptions.

[0010] 2. This utility model uses a food-grade hydrophilic coating and a U-shaped groove to ensure that condensate water is directionally spread throughout the color-changing ink area, avoiding reaction delays or local failures caused by the random distribution of water droplets in traditional labels, thus improving indication accuracy.

[0011] 3. This utility model has a total thickness of three layers that is consistent with existing paper tags. It can directly use existing rope or tie-on equipment. The hydrophilic coating does not require additional processes and is suitable for large-scale mass production. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0015] To facilitate understanding of this utility model, a more comprehensive description of it will be provided below with reference to relevant embodiments. Several embodiments of this utility model are given. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0016] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a fresh food hang tag, including a hang tag body 1, a semi-circular hanging hole 3 on the top of the hang tag body 1, a horizontal information column 2 on the front of the hang tag body 1, and the hang tag body 1 is a three-layer composite structure formed by stacking and hot-pressing an outer layer 5, a middle layer 6 and an inner layer 7 in sequence, wherein the outer layer 5 is a weather-resistant film layer for printing information, the middle layer 6 is a microporous breathable layer, and the inner layer 7 is a cold chain indicator layer.

[0019] As an example of this utility model, the horizontal information column 2 is printed with color-changing ink, and the color-changing ink undergoes an irreversible color change after the change.

[0020] As an example of this utility model, the graphic information printed in the horizontal information bar 2 covers the surface of the outer layer 5 and is offset from the color-changing area.

[0021] As an example of this utility model, the upper part of the inner layer 7 is provided with a condensate zone 9, and the lower part is provided with a guide groove 8 that communicates with the condensate zone 9.

[0022] As an example of this utility model, the guide groove 8 is a food-grade hydrophilic coating.

[0023] Working principle: When in use, first fix the support column 10, then print the information in the horizontal information column 2, and fix the tag body 1 through the semi-circular hanging hole 3. The tag body 1 is attached to the outside of the pre-cooled fresh food packaging. When the cold chain temperature rises, the temperature difference between the inside and outside of the packaging causes water vapor to condense on the low-temperature surface of the inner layer 7 of the tag body 1, forming tiny water droplets. The water droplets first gather in the condensate area 9 and flow down along the pre-formed guide channel 8, covering the color-changing ink area of ​​the outer layer 5. The color-changing ink changes color to intuitively show consumers that the cold chain has been broken. The color change is irreversible. If the tag body 1 needs to be replaced, simply lift the semi-circular hanging hole 3 along the support column 10 to remove it. The guide channel 8 and the tag body 1 are discarded together, with no risk of residue.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
