Detailed Embodiments

[0021] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model clearer and more understandable, the following further describes the utility model in conjunction with the drawings and embodiments.

[0022] Embodiment 1

[0023] As Figure 1 shown, this embodiment provides a rewritable writing sticker, which includes a tracing paper layer 10 and a writing paper layer 20. The tracing paper layer 10 sequentially includes a tracing layer 11, a first PET layer 12 and a first adhesive film layer 13 from bottom to top. A plurality of inwardly concave suction cup holes are provided on the upper surface of the first adhesive film layer 13. The tracing layer 11, the first PET layer 12 and the first adhesive film layer 13 are an integral structure. The writing paper layer 20 sequentially includes a fixedly connected second PET layer 21 and a writing layer 22 from bottom to top. The second PET layer 21 can be physically adsorbed on the first adhesive film layer 13 repeatedly, and the writing layer 22 can be rewritten.

[0024] The tracing paper layer 10 can be physically adsorbed on the writing paper layer 20 through the suction cup holes on the first adhesive film layer 13. The tracing paper layer 10 and the writing paper layer 20 can be adsorbed into one body or can be disassembled independently. The tracing layer 11 can be Chinese tracing, foreign language tracing, digital tracing, graphic tracing, etc. Merchants can provide a suitable tracing layer 11 according to users with different needs to cooperate with the writing paper layer 20 for application together, which is more personalized. The writing layer 22 can be made of existing materials such as UV curable ink treated with synthetic resin, and can be rewritten and wiped repeatedly, that is, it can be traced repeatedly. This writing sticker is thin and light, and is convenient to carry.

[0025] The tracing paper layer 10 further includes a third PET layer 14 and a second adhesive film layer 15. The third PET layer 14 is fixed under the tracing layer 11, and the second adhesive film layer 15 is fixed under the third PET layer 14. A plurality of inwardly concave suction cup holes are provided on the bottom surface of the second adhesive film layer 15.

[0026] By providing the second adhesive film layer 15, the writing sticker can be physically adsorbed on any object with a smooth surface. Users only need to adsorb the writing sticker on the existing object through the second adhesive film layer 15 to achieve tracing, which is convenient to carry.

[0027] The tracing layer 11 and the first PET layer 12 have the same size, and the second PET layer 21 and the writing layer 22 have the same size. The length of the first adhesive film layer 13 is less than the length of the first PET layer 12, the width of the first adhesive film layer 13 is less than the width of the first PET layer 12, and the distance from the edge of the first adhesive film layer 13 to the edge of the first PET layer 12 is 3-8 mm. Thus, when the tracing paper layer 10 and the writing paper layer 20 are adsorbed into one body, a first gap 40 is left between the first PET layer 12 and the second PET layer 21, which is convenient for manual separation of the tracing paper layer 10 and the writing paper layer 20.

[0028] AsFigure 2 As shown in the figure, there is a film unit 131 on the first film layer 13. The suction cup holes are provided on the film unit 131. There is a gap 132 between adjacent film units 131. The width of the film unit 131 is 2 - 3 mm, and the length of the gap 132 is 2 - 3 mm. With such a setting, when the first film layer 13 adsorbs the second PET layer 21, by manual extrusion adsorption, the air between the first film layer 13 and the second PET layer 21 is completely discharged along the gap 132. In this way, the second PET layer 21 is firmly adsorbed on the first film layer 13, realizing the fixation between the tracing paper layer 10 and the writing paper layer 20. The structure of the second film layer 15 is the same as that of the first film layer 13. The structure of the film unit 131 thereon can refer to a suction cup type film disclosed in Chinese Patent CN221113341U.

[0029] There are several tracing paper layers 10, and the tracing contents on the tracing layers 11 in the several tracing paper layers 10 are different. Merchants can match one writing paper layer 20 with one or more tracing paper layers 10 to meet different market demands.

[0030] Example 2

[0031] As Figure 3 and Figure 4 shown in the figure, this example provides a rewritable writing sticker. On the basis of Example 1, it further includes a backing plate layer 30. The backing plate layer 30 sequentially includes a hard backing layer 31, a fourth PET layer 32, and a third film layer 33 from bottom to top. The hard backing layer 31, the fourth PET layer 32, and the third film layer 33 are an integral structure. The bottom surface of the tracing layer 11 can be physically adsorbed on the third film layer 33 repeatedly.

[0032] The structure of the third film layer 33 is the same as that of the first film layer 13. When tracing is needed, the tracing paper layer 10 is adsorbed between the backing plate layer 30 and the writing paper layer 20. The tracing paper layer 10, the backing plate layer 30, and the writing paper layer 20 are combined into one. The hard backing layer 31 has a certain hardness and provides a backing function for writing, eliminating the need to select a specific occasion and enabling tracing anytime and anywhere. When the tracing paper layer 10 needs to be replaced, the tracing paper layer 10 is detached from the adsorption of the first film layer 13 and the third film layer 33, and then a new tracing paper layer 10 is adsorbed between the backing plate layer 30 and the writing paper layer 20. The operation is simple and easy to master.

[0033] The hard cushion layer 31 and the fourth PET layer 32 have the same size. The length of the third adhesive film layer 33 is less than the length of the fourth PET layer 32 and less than the length of the tracing layer 11, and the width of the third adhesive film layer 33 is less than the width of the fourth PET layer 32 and less than the width of the tracing layer 11. The distance from the edge of the third adhesive film layer 33 to the edge of the fourth PET layer 32 is 3 - 8 mm, and the distance from the edge of the third adhesive film layer 33 to the edge of the tracing layer 11 is 3 - 8 mm. Thus, when the tracing paper layer 10 is adsorbed between the backing plate layer 30 and the writing paper layer 20, a second notch 50 is left between the fourth PET layer 32 and the tracing layer 11, facilitating the manual separation of the tracing paper layer 10 and the backing plate layer 30.

[0034] By providing the tracing paper layer 10, the writing paper layer 20, and the backing plate layer 30, the present utility model realizes the variability of the traced content, is convenient to carry around, and adapts to various writing scenarios.

[0035] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall fall within the protection scope of the present utility model.
