Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of stationery, and more specifically to a book cover that can reinforce book corners. Background Technology
[0002] Book covers effectively prevent book covers from wearing out and corners from folding. A book cover typically consists of a top film, an adhesive layer, and a release liner. The top film, as the primary protective layer, is bonded to the release liner via the adhesive layer. To use, simply peel off the release liner and apply the top film smoothly to the cover surface using the adhesive layer. However, book covers are prone to warping and curling at the corners, and current book covers often fail to effectively reinforce these corners. Furthermore, due to varying book thicknesses, the area occupied by the spine on the book cover differs, as does the distance between the book cover's corners and the book cover's edges. Most book covers on the market have either beveled or double right angles at the corners. When covering a book, these angled or double-right-angled covers don't perfectly match the book cover, often requiring users to fine-tune the corners as needed. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a book cover that can reinforce the corners of the book. In addition to protecting the book cover, it can provide multiple layers of reinforcement protection for the corners of the cover, thus doubling the reinforcement of the book corners.
[0004] The technical solution of this utility model is to provide a book cover that can reinforce book corners, including a face film, an adhesive layer, and release paper of the same shape as the face film. The face film is adhered to the release paper by the adhesive layer. The release paper includes a first cover and a second cover. The first cover has folded edges on its upper, lower, and left sides, and the second cover also has folded edges on its upper, lower, and right sides. Two folded edges are provided at the upper left and lower left corners of the first cover and the upper right and lower right corners of the second cover. Each corner reinforcement piece is a right-angled triangle sharing a right-angled side. Two of the corner reinforcement pieces can be folded to one outside the corner and the other inside the corner, with the right angles of the corner reinforcement pieces located on the corners. The hypotenuse and non-shared right-angled side of the corner reinforcement piece used to fold to the inside of the corner are provided with cutting lines. The surface film is provided with the same cutting lines as the release paper. The surface film and the release paper can be torn open simultaneously along any cutting line.
[0005] Compared with existing technologies, the book-covering product of this utility model that can reinforce book corners has the following advantages: When covering a book, first tear open one of the corner reinforcement pieces with the cut lines along the corresponding cut lines. Then, fold the folded edges on both sides of the corresponding corner of the corner reinforcement piece towards the adhesive layer and stick it to the inside of the book cover. Next, fold the two corner reinforcement pieces at the corner to one outside the corner of the book cover and the other inside the corner of the book cover. That is, the surface film on the two corner reinforcement pieces can be stuck to the outside and inside of the corner of the book cover, respectively. In this way, on the basis of protecting the book cover, the corner area of the book cover can be reinforced again with a double layer, doubling the reinforcement of the book corner. Moreover, the two corner reinforcement pieces located on the outside and inside of the corner of the book cover share a right-angled edge, that is, the two corner reinforcement pieces cover one side of the corner of the book cover, resulting in better protection of the corner of the book cover.

The first reinforcement piece cut line I is the dividing line between the first corner reinforcement piece I and the upper end of the first side folding edge, and the first reinforcement piece cut line II is the dividing line between the first corner reinforcement piece I and the left end of the first cover. Using this structure, the two edges of the first corner reinforcement piece I can be torn open along the first reinforcement piece cut lines I and II. Then, the first side folded edge is folded towards the adhesive layer and pasted onto the inside of the book cover. Next, the first upper folded edge is folded towards the adhesive layer and pasted onto the inside of the book cover. At this point, the first corner reinforcement piece I is flipped over to be above the first corner reinforcement piece II, and the adhesive layers of both the first corner reinforcement piece I and the first corner reinforcement piece II are facing outwards. Then, the first corner reinforcement... Fold piece II towards the adhesive layer and stick it to the outside of the upper left corner of the book cover. At this time, the first corner reinforcement piece I also flips over so that the adhesive layer faces inward. Finally, fold the first corner reinforcement piece I towards the adhesive layer and stick it to the inside of the upper left corner of the book cover. In this way, after the first cover and the first folded edge protect the corner on the outside and inside of the upper corner of one side of the book cover, the first corner reinforcement piece I and the first corner reinforcement piece II further reinforce the corner on the inside and outside of the corner.

[0034] In this embodiment, the book-covering material that can reinforce the book corners can be used by first tearing off the spine seal 7 and pasting the corresponding surface film of the spine seal 7 onto the spine of the book; then tearing off the first cover 1 and pasting the corresponding surface film of the first cover 1 onto the outside of one side of the book cover; then tearing open the two edges of the first corner reinforcement piece I1-4 along the first reinforcement piece cut lines I1-8 and II1-9, and then folding the first side folding edge 1-3 towards the adhesive layer and pasting it onto the inside of the book cover, as shown. Figure 2 As shown in the image; then fold the first upward folded edge 1-1 towards the adhesive layer and paste it to the inside of the book cover, as shown. Figure 3 As shown in the diagram, at this point, the first corner reinforcement piece I1-4 is flipped over to be above the first corner reinforcement piece II1-5, and the adhesive layers of both the first corner reinforcement pieces I1-4 and II1-5 are facing outwards; then, the first corner reinforcement piece II1-5 is folded towards the adhesive layer and pasted onto the outer side of the upper left corner of the book cover, as shown.

Figure 5 As shown, the right angle of the first corner reinforcement piece I1-4 is also located on the corner. Thus, after the first cover 1 and the first fold-over edge 1-1 protect the upper corner of the book cover on its outer and inner sides respectively, the first corner reinforcement piece I1-4 and the first corner reinforcement piece II1-5 further reinforce the corner on its inner and outer sides. Then, the other corners of the book are pasted using the same method. The completed book cover is shown below. Figure 6 As shown in the image.

The first reinforcement piece cut line I1-8 is the dividing line between the first corner reinforcement piece I1-4 and the left end of the first upper folding edge 1-1, and the first reinforcement piece cut line II1-9 is the dividing line between the first corner reinforcement piece I1-4 and the upper end of the first cover 1.
[0038] The two corner reinforcement pieces at the lower left corner of the first cover 1 are the second corner reinforcement piece I1-6 located at the left end of the first lower folded edge 1-2 and the second corner reinforcement piece II1-7 located at the lower end of the first side folded edge 1-3. The second reinforcement piece cut line I1-10 is the dividing line between the second corner reinforcement piece I1-6 and the left end of the first lower folded edge 1-2, and the second reinforcement piece cut line II1-11 is the dividing line between the second corner reinforcement piece I1-6 and the lower end of the first cover 1.
[0039] The two corner reinforcement pieces on the upper right corner of the second cover 2 are the third corner reinforcement piece I2-4 set at the right end of the second upper folding edge 2-1 and the third corner reinforcement piece II2-5 set at the upper end of the second side folding edge 2-3. The blade line I2-8 of the third reinforcement piece is the dividing line between the third corner reinforcement piece I2-4 and the right end of the second upper folding edge 2-1, and the blade line II2-9 of the third reinforcement piece is the dividing line between the third corner reinforcement piece I2-4 and the upper end of the second cover 2.
[0040] The two corner reinforcement pieces at the lower right corner of the second cover 2 are the fourth corner reinforcement piece I2-6 located at the right end of the second lower folded edge 2-2 and the fourth corner reinforcement piece II2-7 located at the lower end of the second side folded edge 2-3. The fourth reinforcement piece cut line I2-10 is the dividing line between the fourth corner reinforcement piece I2-6 and the right end of the second lower folded edge 2-2, and the fourth reinforcement piece cut line II2-11 is the dividing line between the fourth corner reinforcement piece I2-6 and the lower end of the second cover 2.
[0041] In this embodiment, the book-covering material that reinforces the book corners is used as follows: After attaching the spine seal 7 and the first cover 1, the two edges of the first corner reinforcement piece I1-4 are torn open along the first reinforcement piece cut lines I1-8 and II1-9. Then, the first upward folded edge 1-1 is folded towards the adhesive layer and pasted onto the inside of the book cover. Next, the first side folded edge 1-3 is folded towards the adhesive layer and pasted onto the inside of the book cover. At this time, the first corner reinforcement piece I1-4 is flipped to the left of the first corner reinforcement piece II1-5, and the first corner reinforcement piece I1-4 and the first corner reinforcement piece II1-5 are aligned. With all adhesive layers of part 5 facing outwards, fold the first corner reinforcement piece II1-5 towards the adhesive layer and attach it to the outer side of the upper left corner of the book cover. At the same time, fold the first corner reinforcement piece I1-4 so that the adhesive layer faces inwards. Finally, fold the first corner reinforcement piece I1-4 towards the adhesive layer and attach it to the inner side of the upper left corner of the book cover. In this way, after the first cover 1 and the first side folded edge 1-3 protect the upper corner of one side of the book cover on the outer and inner sides respectively, the first corner reinforcement pieces I1-4 and II1-5 further reinforce the corner on the inner and outer sides. Then, use the same method to attach the other corners of the book.
[0042] In other embodiments, the two corner reinforcement pieces that share a right-angled side at the same corner may not be symmetrical about the shared right-angled side, or they may not be isosceles right triangles.
