Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of stationery, and more specifically to a book film backing paper and book cover. Background Technology
[0002] Book covers are protective coverings that protect the book cover from wear and tear and corner damage. While the book cover protects the inner pages, damage to the cover corners inevitably leads to similar damage to the inner pages. Book covers are widely used in primary and secondary schools to protect textbooks. A book cover consists of a top layer, an adhesive layer, and a backing paper. The top layer, as the main protective layer, is bonded to the backing paper via the adhesive layer. To use it, simply peel off the backing paper and use the adhesive layer to smoothly adhere the top layer to the cover surface, forming a physical protective barrier. However, when using book covers, the backing paper is usually peeled off entirely. During application, large areas of adhesive can easily stick together or be accidentally applied elsewhere, resulting in a wrinkled cover. This is especially true for the folds on the inside of the cover, which cannot be properly treated during application and can easily stick to the book cover or tabletops, leading to a poor user experience. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a book cover backing paper that can prevent the folded edge of the book cover, which is used to stick to the inside of the cover, from sticking to the book cover or other places such as the desktop during the book wrapping process.
[0004] The technical solution of this utility model is to provide a book film backing paper, which is a one-piece structure with several die-cut lines. The book film backing paper can be torn along any one of the die-cut lines. The die-cut lines include an upper die-cut line, a lower die-cut line, a first side die-cut line, a second side die-cut line, and a longitudinal center die-cut line. A first cover and a second cover are provided on the left and right sides of the longitudinal center die-cut line. The upper die-cut line is located above the first cover and the second cover, and a first upward folding edge and a second upward folding edge are provided above the upper die-cut line. The lower die-cut line is located below the first cover and the second cover, and a first downward folding edge and a second downward folding edge are provided below the lower die-cut line. The first upward folding edge and the first downward folding edge are located above and below the first cover, respectively. The second upward folding edge and the second downward folding edge are located above and below the second cover, respectively. The first side die-cut line is located on the left side of the first cover, and a first side folding edge is provided on the left side of the first side die-cut line. The second side die-cut line is located on the right side of the second cover, and a second side folding edge is provided on the right side of the second side die-cut line.
[0005] Compared with the prior art, the book film backing paper of this utility model has the following advantages: the die-cutting lines are all processed by a creasing machine and are presented as dotted lines on the book film backing paper, which makes it convenient to tear the paper along the die-cutting lines. During the book wrapping operation, the first cover can be torn off first along the upper die-cutting line, lower die-cutting line, first side die-cutting line and longitudinal center die-cutting line. While keeping the second cover, the first upper folding edge, first lower folding edge and first side folding edge around the first cover are also kept. After pasting the book cover corresponding to the first cover, the remaining folding edges are torn off step by step and pasted onto the corresponding book cover parts on the inside of the book cover. Then, the same steps are used to process the second cover and the second upper folding edge, second lower folding edge and second side folding edge around the second cover. In this way, during the entire book wrapping process, the adhesive layers of the book cover will not easily stick to each other or be accidentally pasted to other places.
[0006] Preferably, there are two longitudinal die-cut lines, including a first longitudinal die-cut line and a second longitudinal die-cut line arranged in parallel. A spine seal is provided between the first longitudinal die-cut line and the second longitudinal die-cut line, and the spine seal is located between the first cover and the second cover. With this structure, when covering the book, the spine seal can be torn off first, and the corresponding part of the cover can be pasted onto the spine of the book. This facilitates the subsequent processing of the side covers and helps to make the side covers stick flat.
[0007] Preferably, the lengths of the first upward fold and the first downward fold are both shorter than the lengths of the top and bottom edges of the first cover, and the length of the first side fold is shorter than the length of the side edge of the first cover. This structure facilitates attaching the first upward fold, the first downward fold, and the first side fold to the inside of the corresponding book cover, reducing adhesion.
[0008] Preferably, the lengths of the second upward fold and the second downward fold are both shorter than the lengths of the top and bottom edges of the second cover, and the length of the second side fold is shorter than the length of the side edge of the second cover. This structure facilitates attaching the second upward fold, the second downward fold, and the second side fold to the inside of the corresponding book cover, reducing adhesion.
[0009] Preferably, the die-cutting line further includes a transverse middle die-cutting line, located between the upper and lower die-cutting lines, which divides both the first and second covers into upper and lower parts. With this structure, both the first and second covers can be torn apart into upper and lower parts, reducing the area required for a single operation, facilitating smooth book cover pasting, and reducing adhesion.
[0010] Preferably, the die-cutting lines further include a first oblique die-cutting line and a second oblique die-cutting line. Both the first and second oblique die-cutting lines are located between the upper and lower die-cutting lines. The first oblique die-cutting line divides the first cover into two parts, and the second oblique die-cutting line divides the second cover into two parts. With this structure, both the first and second covers can be glued together as upper and lower parts, reducing the area required for a single operation, facilitating smooth glue application, and minimizing adhesion.
[0011] This utility model also provides a book cover, comprising a top layer film, an adhesive layer, and a backing paper of the same shape as the top layer film. The top layer film is adhered to the backing paper via the adhesive layer. The backing paper is the book film backing paper described above. Using this structure, during book wrapping, the folded edges on the book cover used for pasting the inside of the cover can be prevented from adhering to the book cover or other surfaces such as a desktop, facilitating a smoother book cover application and reducing adhesion.

[0020] Example 1:
[0021] like Figure 1 As shown, the book film backing paper of this utility model has a one-piece structure with several die-cut lines. The book film backing paper can be torn along any one of the die-cut lines. The die-cut lines include an upper die-cut line 3, a lower die-cut line 4, a first side die-cut line 5, a second side die-cut line 6, and a longitudinal center die-cut line 7. A first cover 1 and a second cover 2 are provided on the left and right sides of the longitudinal center die-cut line 7. The upper die-cut line 3 is located above the first cover 1 and the second cover 2. A first upward folding edge 1-1 and a second upward folding edge 2-1 are provided above the upper die-cut line 3. The lower die-cut line 4 is located above the first cover 1 and the second cover 2. Below the cover 2, below the lower die-cut line 4, there are a first downward folding edge 1-2 and a second downward folding edge 2-2. The first upward folding edge 1-1 and the first downward folding edge 1-2 are located above and below the first cover 1, respectively. The second upward folding edge 2-1 and the second downward folding edge 2-2 are located above and below the second cover 2, respectively. The first side die-cut line 5 is located on the left side of the first cover 1, and the first side folding edge 1-3 is located on the left side of the first side die-cut line 5. The second side die-cut line 6 is located on the right side of the second cover 2, and the second side folding edge 2-3 is located on the right side of the second side die-cut line 6.
[0022] An adhesive layer is provided on the backing paper of the book cover of this utility model, and then a surface film of the same shape as the backing paper is attached to form the book cover of this utility model. When wrapping books, the first cover 1 can be torn off along the upper die-cut line 3, lower die-cut line 4, first side die-cut line 5, and vertical center die-cut line 7. While keeping the second cover 2, the first upper fold-over edge 1-1, first lower fold-over edge 1-2, and first side fold-over edge 1-3 around the first cover 1 are also kept. After pasting the corresponding book cover part of the first cover 1, the first upper fold-over edge 1-1, first lower fold-over edge 1-2, or first side fold-over edge 1-3 are torn off step by step, and the corresponding book cover parts are pasted on the inside of the book cover. Then, the same steps are used to process the second cover 2 and the second upper fold-over edge 2-1, second lower fold-over edge 2-2, and second side fold-over edge 2-3 around the second cover 2. In this way, during the entire book wrapping process, the fold-over edges on the book cover used to paste on the inside of the cover can be avoided from sticking to the book cover or other places such as the desktop, which is conducive to pasting the book cover flat and reducing adhesion.
[0023] Example 2:
[0024] like Figure 2 As shown, the difference between the book cover paper in this embodiment and that in Embodiment 1 is that there are two longitudinal die-cut lines 7, including a first longitudinal die-cut line 9 and a second longitudinal die-cut line 10 arranged in parallel. A spine seal 8 is provided between the first longitudinal die-cut line 9 and the second longitudinal die-cut line 10, and the spine seal 8 is located between the first cover 1 and the second cover 2. In this embodiment, when wrapping a book, the spine seal 8 can be torn off first, and the corresponding part of the book cover can be pasted onto the spine of the book. This facilitates the subsequent processing of the two side covers separately and helps to smooth the pasting of the book covers on both sides.
[0025] Example 3:
[0026] like Figure 3 As shown, the difference between the book cover paper in this embodiment and that in embodiment 2 is that the die-cutting line further includes a horizontal central die-cutting line 11. The horizontal central die-cutting line 11 is located between the upper die-cutting line 3 and the lower die-cutting line 4, and it divides both the first cover 1 and the second cover 2 into upper and lower parts. In this embodiment, when wrapping the book, both the first cover 1 and the second cover 2 can be torn apart into upper and lower parts, reducing the area required for a single pasting operation, which helps to smooth the book cover and reduce adhesion.
[0027] Example 4:
[0028] like Figure 4As shown, the difference between the book cover paper in this embodiment and that in embodiment 2 is that the die-cutting lines further include a first oblique die-cutting line 12 and a second oblique die-cutting line 13. Both the first oblique die-cutting line 12 and the second oblique die-cutting line 13 are located between the upper die-cutting line 3 and the lower die-cutting line 4. The first oblique die-cutting line 12 divides the first cover 1 into two parts, and the second oblique die-cutting line 13 divides the second cover 2 into two parts. In this embodiment, when wrapping the book, both the first cover 1 and the second cover 2 can be torn apart into upper and lower parts, reducing the area of a single pasting operation, which helps to paste the book cover smoothly and reduces adhesion.
[0029] In other embodiments, the lengths of the first upward folding edge 1-1 and the first downward folding edge 1-2 can be set to be shorter than the lengths of the top and bottom edges of the first cover 1, the length of the first side folding edge 1-3 can be set to be shorter than the side edge length of the first cover 1, the lengths of the second upward folding edge 2-1 and the second downward folding edge 2-2 can be set to be shorter than the lengths of the top and bottom edges of the second cover 2, and the length of the second side folding edge 2-3 can be set to be shorter than the side edge length of the second cover 2. This facilitates pasting the second upward folding edge 2-1 and the second downward folding edge 2-2 onto the inside of the corresponding book cover, reducing the risk of uneven pasting.
[0030] The above are merely specific embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Any modifications or equivalent substitutions to this utility model without departing from its spirit and scope should be covered within the protection scope of the claims of this utility model.
