[0028] In the description of the present utility model, unless otherwise clearly defined, terms such as "set", "installed", "connected", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0029] Reference will be made below Figures 1 - 4 to describe the reusable masking tape according to an embodiment of the present utility model.

[0030] As Figures 1 - 4 shown, the reusable masking tape includes a masking tear layer 100, an end identification layer 120, an adhesive layer 130, a substrate layer 140, and an adhesive layer 150 that are connected in sequence. The strip-shaped tape is wound into a roll for use. Both the adhesive layer 130 and the adhesive layer 150 are used as adhesives. The adhesive layer 150 enables the substrate layer 140 to adhere to the surface of the paper-based material, and the adhesive layer 130 enables the masking tear layer 100 and the end identification layer 120 to adhere to the surface of the substrate layer 140.

[0031] Specifically, the masking tear layer 100 covers the surface of the substrate layer 140, and the content in the overlapping area between the masking tear layer 100 and the substrate layer 140 is blocked by the masking tear layer 100, so that the content covered by the masking tear layer 100 cannot be seen by the user. The substrate layer 140 is a common transparent substrate, and the area covered by the substrate layer 140 does not affect the user's viewing of the content.

[0032] A writing area 110 is provided on the surface of the masking tear layer 100. The writing area 110 is used for writing content. When the masking tear layer 100 is separated from the substrate layer 140, the user can observe the content in the corresponding area through the substrate layer 140. When the paper-based material needs to be repeatedly practiced or certain articles of the paper-based material need to be recited and filled in the blanks, the user first covers the paper surface with the reusable masking tape of the present utility model, and the masking tear layer 100 is aligned with the content to be covered and pasted. The old content and the part to be recited of the pasted paper-based material will not be directly observable. At this time, the user can perform secondary practice, dictation, filling in the blanks, etc. in the writing area 110 of the masking tear layer 100.

[0033] In the process of traditional hand covering the content for repeated learning, the user will be in a state of continuous observation and review. When encountering content that they don't know, they will directly view the answers and content, resulting in low review efficiency and discontinuous review time. It is difficult for the user to enter the learning state and study efficiently.

[0034] The reusable masking tape of the present utility model can completely cover the area that originally needed to be blocked by the hand. The user can directly write on the masking and tearing layer 100, effectively avoiding the situation where the user reviews while looking at the answers, effectively improving the review efficiency, and enabling more effective learning. After one round of review, only need to tear off the masking and tearing layer 100, and compare the content on the masking and tearing layer 100 with the covered content to quickly check the answers and improve the review efficiency.

[0035] In some embodiments of the present utility model, such as Figure 1 and Figure 2 shown, the bottom of the masking and tearing layer 100 is covered with an end identification layer 120, and the end identification layer 120 is clamped between the base material layer 140 and the masking and tearing layer 100.

[0036] Specifically, the color of the end identification layer 120 and the color of the masking and tearing layer 100 are in different color systems, so that the end identification layer 120 can be quickly identified. When the user is looking for the end of the tape roll, as long as finding the position where the end identification layer 120 protrudes, the end can be quickly located, and thus the end of the tape can be quickly pulled out.

[0037] Furthermore, the width of the masking and tearing layer 100 is not less than the width of the end identification layer 120. Specifically, the end identification layer 120 is clamped between the masking and tearing layer 100 and the base material layer 140, and it is mainly used for end identification, and its width can be adjusted according to actual production.

[0038] In some embodiments of the present utility model, the surface of the masking and tearing layer 100 is provided with a rough texture (not shown in the drawings), and the rough texture is used to improve the ink adhesion performance of the writing area 110. Specifically, the surface of the masking and tearing layer 100 is provided with a rough texture, which can increase the rolling friction of the pen tip ball on the masking and tearing layer 100, thereby improving the ink adhesion performance of the writing area 110, and the ink can be more easily written on the masking and tearing layer 100, improving the ink-jetting ability of the gel pen.

[0039] Furthermore, the masking and tearing layer 100 is made of a paper base material. The paper base material can adopt cotton paper material, which has the characteristics of good toughness and easy tearing. When too much text content is pasted and covered, the user can manually tear off the covered part of the text content. The cotton paper material is a well-known technical solution to those skilled in the art and will not be described in detail in this embodiment.

[0040] In some embodiments of the present utility model, such as Figures 1 - 3 shown, the two sides of the masking and tearing layer 100 are spaced from the two sides of the base material layer 140, and the masking and tearing layer 100 is located in the middle of the surface of the base material layer 140. Specifically, the width of the masking and tearing layer 100 is 7 mm to 10 mm, and the width of the writing area 110 is equal to the width of the masking and tearing layer 100.

[0041] Specifically, the width of the covering and tearing layer 100 is mainly adjusted according to the text size of the paper book specification. Users can select tape rolls with different widths according to the text size, which can avoid the situation that the covering and tearing layer 100 does not cover completely or covers the text on the upper and lower layers.

[0042] Furthermore, the ratio of the width of the covering and tearing layer 100 to the width of the substrate layer 140 is 0.6 - 0.9.

[0043] In some embodiments of the present utility model, the light transmittance of the covering and tearing layer 100 is less than that of the substrate layer 140. This prevents users from observing the text content covered at the bottom of the substrate layer 140 through the covering and tearing layer 100.

[0044] In the description of this specification, the description with reference to terms such as "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples", etc. means that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0045] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
