Abstract
Description
Technical Field
[0001] This utility model relates to the field of correction tape technology, specifically to a paper-colored correction tape core with strong back-side coding and light-blocking properties. Background Technology
[0002] Correction tape is a common stationery item used by students. It can be used to correct misspelled words and is also known as correction tape. Correction tape is a white, opaque pigment similar to correction fluid. It is applied to paper to cover up mistakes and can be rewritten immediately, providing convenience for study and work. The main components of correction tape include: AS, PS, resin, titanium dioxide, etc.
[0003] Traditional correction tape cores typically come in several forms, such as: double-sided pure white, double-sided beige, or pure white on the front with text or patterns printed on the back (the latter being called encrypted tape). However, traditional cores are prone to the following problems in practical use: 1. When traditional white tape is used on beige paper, the white front of the tape contrasts sharply with the beige paper, making it quite noticeable and affecting the aesthetics. This can also interfere with the eyesight of students or other users to some extent. 2. Traditional double-sided white or double-sided beige paper cores are not very effective at covering errors. After applying the core, the original writing is easily visible through. Some papers on the market also allow the original writing to be seen on the back of the paper after applying the core. Utility Model Content
[0004] To address the aforementioned issues, a correction tape core with strong back-side coding and light-blocking properties is provided. By setting the correction layer of the core body to be beige, it can blend with the color of books or notebooks, making it difficult to detect corrections by the naked eye when errors occur. This ensures that the corrections are not conspicuous or too abrupt, thus avoiding visual interference. Furthermore, by incorporating text, letters, symbols, lines, and any combination thereof into the covering layer of the core body, errors can be effectively concealed, preventing them from standing out due to shallow corrections. This also helps to prevent the errors from being leaked to a certain extent.
[0005] To address the existing technical problems, this utility model provides a correction tape core with strong back-side coding and light-blocking properties, comprising a core body, the core body including a base tape layer, a correction layer and a cover layer connected in sequence; the correction layer is connected to the base tape layer, and the side of the correction layer away from the base tape layer is connected to the cover layer; the correction layer is set to a beige or light yellow color that blends with the paper.
[0006] As a further embodiment of this invention, the covering layer is printed with a pattern for covering up erroneous characters.
[0007] As a further embodiment of this utility model, the pattern for covering up erroneous handwriting can be characters, letters, symbols, lines, or any combination thereof.
[0008] As a further embodiment of this invention, the pattern printed on the covering layer for covering up erroneous characters has a width of 5-8mm.
[0009] The advantages of this utility model compared to the prior art are: 1. By setting the correction layer of the core body to be beige, it can blend with the color of the paper of books or exercise books, so that when there is a writing error, it can be covered up and it is not easy to see the correction by the naked eye. This makes the correction position inconspicuous or too abrupt, so as not to interfere with eyesight, thereby improving the coverage of the correction. 2. By setting text, letters, symbols, lines, and any combination thereof in the covering layer of the core body, errors can be covered up, and the errors will not stand out because the correction marks are too shallow. At the same time, the errors can be prevented from being leaked to a certain extent. Attached Figure Description

Figure 2 This is a schematic diagram of the core structure of a correction tape core made of base paper with strong back-side coding and light-blocking properties.
[0011] The labels in the diagram are: 1. Core body; 2. Base layer; 3. Coating layer; 4. Masking layer. Detailed Implementation
[0012] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.
[0013] Reference Figures 1 to 2 As shown, a correction tape core with strong back-side coding and light-blocking properties is provided, comprising a core body 1. The core body 1 includes a base tape layer 2, a correction layer 3, and a cover layer 4 connected in sequence. The correction layer 3 is connected to the base tape layer 2, and the cover layer 4 is connected to the side of the correction layer 3 away from the base tape layer 2 to improve the covering power of the correction. The correction layer 2 is set to a beige or light yellow color that blends with the paper.
[0014] By setting the core body 1 as a base layer 2, an correction layer 3, and a masking layer 4, the masking layer 4 can quickly adhere to the wrong position on the paper of the book or exercise book when the correction tape is used. At the same time, the masking pattern of the masking layer 4 adheres to the paper to cover the wrong content so that it cannot be seen through the core body 1. The correction layer 3 is used for further new writing.
[0015] By setting the correction layer 3 of the core body 1 to be beige, it can blend with the color of the paper in books or exercise books, so that when there is a mistake in the writing, it can be covered up and it is not easy to see the correction by the naked eye. This makes the correction position inconspicuous or too abrupt, so as not to interfere with eyesight.
[0016] By setting the correction layer 3 to beige, it can help to better match the color of the paper in the book or exercise book. Since most of the paper used in books is yellowish, this setting is mainly to protect the eyesight of students or users. Therefore, the correction layer 3 of the core body 1 of this correction tape is also set to beige. This setting can both match the color of the paper and achieve the function of protecting the eyes.
[0017] It should be added that beige is preferred in this solution. Of course, if books and exercise books have other eye-friendly colors, the correction layer 3 of this correction tape can also be set in color according to specific needs, and is not limited to the preferred method in this solution.
[0018] Specifically, the cover layer 4 is printed with patterns used to cover up erroneous characters.
[0019] By setting text, letters, symbols, lines, and any combination thereof on the covering layer 4 of the core body 1, the erroneous content can be covered up, and the erroneous content will not stand out because the correction trace is too shallow. At the same time, the erroneous content can be prevented from being leaked to a certain extent.
[0020] Specifically, the pattern used to cover up the erroneous handwriting can be text, letters, symbols, lines, or any combination thereof.
[0021] The masking layer 4 can cover up erroneous content or other content containing private information. However, in existing correction tapes, the masking layer 4 is usually the same color as the correction layer 3 or is only white. When applied, light still passes through, making the erroneous content visible. In this solution, the masking layer 4 is printed with a pattern used to cover up erroneous writing, which can further cover up the erroneous content without the phenomenon of light transmission.
[0022] It should be further noted that the preferred patterns in this solution are text, letters, symbols, lines, and any combination thereof. Other patterns such as designs and QR codes can also be used to cover up the erroneous content without allowing light to pass through, and it is not limited to the preferred methods in this solution.
[0023] Specifically, the pattern printed on the covering layer 4 to cover up erroneous characters has a width of 5-8mm.
[0024] By setting the width of the covering layer 4 to 5-8mm, it can be applied to different books or exercise books where corrections are needed. For example, some exercise books have different forms of content such as grid paper, single-line book, and double-line book, which enhances the adaptability and practicality of the correction tape core.
[0025] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
