Abstract

The structure of a temperature-sensitive color-changing sticker includes: a surface layer on which a plurality of temperature-sensitive material layers are disposed; an adhesive layer attached to the bottom surface of the surface layer, and a peeling layer provided on the upper surface of the adhesive layer When the surface layer is peeled off from the adhesive layer, it will be taken away from the peeling layer on the surface of the adhesive layer, so that the peeling layer will display a mark symbol, so as to indicate that the surface layer has been peeled off. If the surface layer is heated, the color-changing effect of the temperature-sensitive material layer provided on the surface can be judged, and an attempt by an external force to attempt to recover the marking symbol of the peeling layer by heating can be determined to ensure that the sticker can be determined whether Encountered for the purpose of being ripped off.

Description

Structure of thermochromic sticker

This creation relates to the structure of a temperature-sensitive color-changing sticker, especially a sticker structure that can achieve anti-counterfeiting purposes by sensing color change after sensing high temperature.

In addition to being used for labeling purposes, stickers are also sealed to prevent others from unpacking. At present, the most common method is to make stickers with a fragile material. When attached to the product's packaging, If someone else removes the sticker, it will cause the sticker to become fragmented, so that you can know that the sticker has been removed to achieve the purpose of anti-counterfeiting. However, although the sticker is made of a fragile material It is possible to restore the sticker to its original state by applying special chemical liquids or special methods, so it cannot achieve the effect of complete anti-counterfeiting.

Therefore, how to improve the above problems is the technical difficulty that the creators of this case want to solve.

The main purpose of this creation is: a structure of a thermosensitive color-changing sticker, which includes: a surface layer on which a plurality of thermosensitive material layers are disposed on the surface; an adhesive layer attached to the bottom surface of the surface layer, and the adhesive A release layer is provided on the upper surface of the layer; when the surface layer is peeled off from the adhesive layer, it will be taken away from the release layer on the surface of the adhesive layer, so that the release layer displays a marking symbol, thereby representing the surface layer The tearing operation has been performed, and if the surface layer is heated, The discoloration effect can be produced on the temperature-sensitive material layer provided on the surface, and it can be judged that an attempt by an external force to recover the marking symbol of the peeling layer by heating is used to achieve the purpose of ensuring whether the sticker has been manually removed.

Please refer to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, which are the three-dimensional appearance drawing, three-dimensional exploded view and the schematic diagram of the preferred embodiment of this creation, which can be clearly seen from the figure. The thermosensitive color-changing sticker 1 of this creation mainly includes: a surface layer 2 on which a plurality of temperature-sensitive material layers 21 are arranged on the surface; an adhesive layer 3 attached to the bottom surface of the surface layer 2 and the adhesive layer 3 The upper surface is provided with a plurality of peeling layers 31; among them, the temperature-sensitive material layer 21 is made of a material that can change color; in which, the surface layer 2 is additionally provided with a printed mark 22; When the color-changing sticker 1 is used, it is directly placed on the desired position, such as Figures 3 and 4, and if the person who wants to remove the temperature-sensitive color-changing sticker 1 will remove it, When the surface layer 2 is peeled off, the release layer 31 on the surface of the adhesive layer 3 is also taken off at the same time, so that the adhesive layer 3 is peeled off from the tape. There is a color difference between the two parts of layer 31, so that the text (numbers or symbols) can be displayed. Even if the surface layer 2 is pasted back to the adhesive layer 3, the displayed text (number or Symbol), so as to ensure that the sticker can be judged whether it has been removed manually; in addition, as shown in Figure 5, users can use a hair dryer or other equipment that can generate heat to the surface layer 2 heating, at this time, the temperature-sensitive material layer 21 on the surface of the surface layer 2 will produce a color-changing effect, and finally a symbol (text or number) is displayed, and the user can know that the temperature-sensitive color-changing sticker 1 is a real product, It is not a fake sticker affixed by others to achieve the purpose of anti-counterfeiting; according to the above, in addition to the temperature-sensitive material layer 21 is made of a material that changes color, it is irreversible after the color change effect is generated by heating. This state, that is to say, even if others use cooling or other methods, the temperature-sensitive material layer 21 cannot be restored to the original state. In summary, compared with the various defects and conventional anti-counterfeiting effects of conventional stickers, This In addition to the temperature-sensitive color-changing sticker 1, in addition to the peeling layer 31 provided on the upper surface of the adhesive layer 3, after the surface layer 2 is removed, the color difference is used to achieve the purpose of anti-counterfeiting and theft prevention, and the surface layer 2 is provided with a feeling on the surface The warm material layer 21 produces an irreversible discoloration effect after heating. It can also prevent others from changing the thermochromic sticker 1 into a fake sticker. Under the design of this double protection effect, it can fully ensure that it can be judged. Whether the sticker has been artificially removed.

The above-exemplified embodiments are used to clarify one of the best feasible embodiments of this creation, and are not intended to limit the scope of this creation. Anyone skilled in this art can do some things without departing from the spirit and scope of this creation. Changes and retouching, so the scope of protection of this creation shall be determined by the scope of the attached patent application.

Claims (3)

The structure of a temperature-sensitive color-changing sticker includes: a surface layer on which a plurality of temperature-sensitive material layers are disposed; an adhesive layer attached to the bottom surface of the surface layer, and a peeling layer provided on the upper surface of the adhesive layer When the surface layer is peeled off from the adhesive layer, it will be taken away from the peeling layer on the surface of the adhesive layer, so that the peeling layer will display a mark symbol, so as to indicate that the surface layer has been peeled off. If the surface layer is heated, the color-changing effect of the temperature-sensitive material layer provided on the surface can be judged, and an attempt by an external force to attempt to recover the marking symbol of the peeling layer by heating can be determined to ensure that the sticker can be determined whether Encountered for the purpose of being ripped off.
