Abstract
Description
Technical Field
[0001] This utility model relates to the field of exercise book technology, and more specifically to a waterproof and tear-resistant exercise book. Background Technology
[0002] Workbooks are generally used for writing assignments, such as for students to complete various written assignments given by teachers. Workbooks can be blank or have lines or grids to facilitate writing and drawing.
[0003] The existing notebook, as shown in application number CN201220196597.8, is a waterproof cloth-covered notebook. It is described that "by covering the cover, back cover and spine with a layer of waterproof woven cloth, the notebook can be made wear-resistant and fold-resistant while also being waterproof, which greatly extends the service life of the notebook".
[0004] The notebook mentioned above uses components to improve its waterproof function through the outer cover (i.e., cover, back cover and spine), but the pages can still get wet, especially the edges. Therefore, the notebook still has the drawback of being relatively limited in terms of waterproofing. Utility Model Content
[0005] The purpose of this utility model is to provide a waterproof and tear-resistant exercise book in order to solve the above-mentioned technical problems.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] This utility model proposes a waterproof and tear-resistant exercise book, including an exercise body and paper pages on it. The two sides of the paper pages are respectively covered with a writing surface and a border surface, with the border surface located outside the writing surface.
[0008] A protective coating with waterproof, wear-resistant and soft functions is fixedly provided on the edge surface, and the protective coating on both sides of the paper is connected to the outer periphery of the paper.
[0009] As a preferred embodiment of this invention, the protective coating is a polyurethane coating.
[0010] As a preferred embodiment of this invention, the thickness of the polyurethane coating is ~ micrometers.
[0011] As a preferred technical solution of this utility model, it also includes an annular protrusion fixed to the top of the protective coating, the annular protrusion surrounding the outer side of the writing surface.
[0012] As a preferred technical solution of this utility model, the working body is also provided with an outer sealing layer, and the paper sheets are provided in multiple groups and are stacked in sequence from top to bottom to form a paper core layer. One side of the multiple groups of paper sheets is fixed in sequence, and the inner side of the outer sealing layer is fixed to the paper core layer.
[0013] As a preferred technical solution of the present utility model, a side convex strip is fixedly arranged at the top end of the protective coating, and the side convex strip is located between the fixation of two adjacent groups of paper pages, the paper core layer and the outer sealing layer.
[0014] The beneficial effects of the present utility model are as follows:
[0015] By adding a protective coating on the peripheral surface, and as shown in the figure, the protective coatings at the upper and lower ends are connected integrally at the periphery of the paper page, so that the periphery of the paper page can be completely blocked, greatly improving the waterproof and wear-resistant effects; and increasing the overall tear resistance of the paper page; and after the periphery of the paper page is treated with the protective coating, the anti-rolling property of this position can be improved, and the aesthetics is well preserved; the arranged ring convex can provide a blocking effect when water flows towards the writing surface after contacting the periphery of the peripheral surface of the paper page, further enhancing the waterproof property.

[0020] As Figures 1-3 shown, this embodiment proposes: a waterproof and tear-resistant exercise book, including an operation body 1 and a paper page 2 thereon. The two side surfaces of the paper page 2 are respectively covered with a writing surface 3 and a peripheral surface 4, and the peripheral surface 4 is located outside the writing surface 3; as Figure 3 shown, the central position of the paper page 2 is the writing surface 3, and the peripheral part of the writing surface 3 is a "return" - shaped peripheral surface 4;
[0021] A protective coating 5 with waterproof, wear-resistant and soft functions is fixedly arranged on the peripheral surface 4, and the protective coatings 5 on the two side surfaces of the paper page 2 are connected integrally at the periphery of the paper page 2; by adding a protective coating 5 on the peripheral surface 4, and as Figure 2 shown, the protective coatings 5 at the upper and lower ends are connected integrally at the periphery of the paper page 2, so that the periphery of the paper page 2 can be completely blocked, greatly improving the waterproof and wear-resistant effects; and increasing the overall tear resistance of the paper page 2; and after the periphery of the paper page 2 is treated with the protective coating 5, the anti-rolling property of this position can be improved, and the aesthetics is well preserved.
[0022] Among them, the protective coating 5 is a polyurethane coating, which has excellent waterproof performance, wear resistance and durability, and good softness; the thickness of the polyurethane coating is 1~10 micrometers, which does not affect the softness. Example 2:
[0023] like Figures 1-3 As shown, the difference between this and Example 1 is that it also includes an annular protrusion 6 fixed to the top of the protective coating 5, and the annular protrusion 6 surrounds the outside of the writing surface 3; the annular protrusion 6 can be integrally formed after the protective coating 5 is processed by hot pressing, which is simple to manufacture; the annular protrusion 6 can provide a blocking effect when water flows into the writing surface 3 after contacting the outer edge 4 of the paper 2. This further enhances the waterproofness. Example 3:
[0024] like Figures 1-3 As shown, the difference between this and Embodiment 1 is that: the main body 1 is further provided with an outer cover layer, and multiple sets of paper sheets 2 are stacked sequentially from top to bottom to form a paper core layer. One side of each set of paper sheets 2 is fixed sequentially, and the inner side of the outer cover layer is fixed to the paper core layer. Multiple sets of paper sheets 2 are stacked sequentially from top to bottom, and the left side of each paper sheet 2 can be connected and fixed together using adhesive or other methods to form a paper core layer. The paper core layer is then placed inside the outer cover layer, and connected and fixed together from the left side of the outer cover layer using adhesive or other methods, thus forming a... Figure 1 The main body of the operation is shown as page turning from right to left;
[0025] The protective coating 5 has a side protrusion 7 fixed at its top, and the side protrusion 7 is located between two adjacent sets of paper sheets 2 and the core layer and outer sealing layer; for example Figure 3 As shown, raised strips 7 are respectively set on the upper and lower sides of the left end of the paper sheet 2. The raised strips 7 are fixed between the stacked paper sheets 2, and the raised strips 7 are fixed between the outer cover layer and the paper core layer to increase the strength at this position. When the paper sheet 2 is torn at this position, the tear resistance can be further increased.
[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0027] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
