Description

Technical Field

[0001] The utility model relates to the field of color-changing stickers, in particular to a temperature-sensitive color-changing sticker. Background Art

[0002] In addition to being used for marking purposes, stickers can also be used to seal packages to prevent others from opening them. Currently, the most common practice is to make stickers out of fragile materials. Once affixed to the packaging of a product, if someone tears off the sticker, it will break into pieces, indicating that the sticker has been torn off, thereby achieving the purpose of anti-counterfeiting. However, stickers are made of fragile materials, but they can still be restored to their original state by applying special chemical liquids or special methods, so they cannot achieve a complete anti-counterfeiting effect. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the utility model provides a temperature-sensitive color-changing sticker, which is adhered to the color-changing sticker in a connecting belt and an inner groove is provided for protection, and the outer side of the connecting belt is connected and fixed to the outer ring belt through the connecting belt. Therefore, after the sticker contacts the external surface, when encountering external force, a corner of the outer ring belt is torn up, the connecting belt will break, and then the connecting belt remains in its original state. If the connecting belt is lifted up, the groove opened on the outer side of the connecting belt can be cut off from a specific direction to reduce the involvement of the color-changing sticker. If the inner sticker is lifted up beyond the groove, the inner groove structure provided between the inner sticker and the color-changing sticker can protect the internal color-changing sticker for the third time. The inner sticker can be torn along the inner groove, and the color-changing sticker and the inner part of the inner sticker will not be involved and warped, thereby achieving an anti-tearing effect. Therefore, when the device is used in practice, the triple protection effect of the inner side can protect the internal color-changing sticker.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a temperature-sensitive color-changing sticker, comprising an outer ring belt, a connecting belt is arranged on the inner side of the outer ring belt, the inner side of the connecting belt is fixedly connected to the outer side wall of the inner sticker, a color-changing sticker is attached to the middle part of the inner sticker, and a groove is opened inward on the outer side wall of the inner sticker.

[0005] As a preferred technical solution of the utility model, the connecting belts are arranged in a plurality of groups in an equidistant array on the inner side wall of the outer ring belt, and the connecting belts and the outer ring belt are an integral structure.

[0006] As a preferred technical solution of the utility model, the cutting grooves are provided in multiple groups on the outer sides of both sides of the inner sticker, and each group of the cutting grooves is a structure inclined to the side of the inner sticker.

[0007] As a preferred technical solution of the utility model, an inner groove is provided between the outer side wall of the color-changing sticker and the inner sticker.

[0008] As a preferred technical solution of the utility model, the outer sides of the outer ring belt and the inner sticker are both rounded structures.

[0009] As a preferred technical solution of the present utility model, the gap of the inner groove is three millimeters.

[0010] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0011] In the present device, the color-changing sticker is adhered to the connecting belt and an inner groove is provided for protection, and the outer side of the connecting belt is connected and fixed to the outer ring belt through the connecting belt. Therefore, after the sticker contacts the external surface, when encountering external force, a corner of the outer ring belt is torn up, the connecting belt will break, and then the connecting belt remains in its original state. If the connecting belt is lifted up, the groove opened on the outer side of the connecting belt can be cut off from a specific direction to reduce the involvement of the color-changing sticker. If the inner sticker is lifted up beyond the groove, the inner groove structure provided between the inner sticker and the color-changing sticker can protect the inner color-changing sticker for the third time. The inner sticker can be torn along the inner groove, and the color-changing sticker and the inner part of the inner sticker will not be involved and warped, thereby achieving an anti-tearing effect. Therefore, when the present device is used in practice, the triple protection effect of the inner side can protect the inner color-changing sticker. BRIEF DESCRIPTION OF THE DRAWINGS
