Description

Technical Field

[0001] This technical solution relates to the field of stationery technology, specifically to a book cover. Background Technology

[0002] Book covers are a common stationery item whose main function is to cover the outside of books and protect them from damage. A book cover consists of a protective film, an adhesive layer, and a backing paper. The adhesive layer is placed on top of the protective film, and the backing paper is then placed on top of the adhesive layer. To use a book cover, the backing paper must be peeled off, allowing the protective film to adhere to the book's surface, thus providing protection.

[0003] However, existing book covers still have some shortcomings: the backing paper is a single sheet of paper that covers the entire adhesive layer. If the entire backing paper is completely peeled off during use, the adhesive layer of the protective film will be fully exposed, making it easy to accidentally stick it to non-target areas, such as crooked or misaligned adhesion. If only part of the backing paper is peeled off to wrap the book, the unpeeled part of the backing paper is still connected to the peeled part. The protective film must be pasted onto the book while peeling off the backing paper, which is difficult and inconvenient to use. Utility Model Content

[0004] The purpose of this technical solution is to provide a book cover that, by dividing the backing paper into several backing paper pieces, allows users to peel off the corresponding backing paper pieces in stages according to actual pasting needs, thereby improving the inconvenience caused by the use of a single sheet of backing paper in existing book covers.

[0005] The purpose of this technical solution is achieved as follows:

[0006] A book cover includes a protective film, an adhesive layer, and a backing paper. The adhesive layer is disposed on one side of the protective film, and the backing paper is adhered to the adhesive layer. The backing paper has a plurality of tear lines that divide the backing paper into a plurality of backing paper pieces; or, the backing paper comprises a plurality of backing paper pieces that are spaced apart from each other.

[0007] Preferably, the backing paper includes: backing paper one, backing paper two, and backing paper three; backing paper one covers the left half of the protective film, backing paper two covers the middle of the protective film, and backing paper three covers the right half of the protective film.

[0008] Preferably, the third backing paper is provided with an alignment line, and the alignment line and the edge of the third backing paper near the second backing paper form a positioning area, which is used for the placement and alignment of the book.

[0009] Preferably, the base paper is made of paper material.

[0010] Preferably, the base paper is made of PET material.

[0011] Preferably, the protective film includes: a spine, two cover sections, and several inward-folding sections, wherein the two cover sections are located on both sides of the spine, and the several inward-folding sections are located at the edges of the cover sections.

[0012] Preferably, each of the four corners of the protective film is provided with a tear line, which forms corner protectors at the four corners of the protective film, and the corner protectors are used to be pasted on the corners of the inner pages of a book.

[0013] Preferably, a second tear line is provided between the end of the spine and the corresponding inward turning part, the second tear line being used to separate the spine and the inward turning part.

[0014] Preferably, the spine is rectangular, the cover is rectangular, the inward-folding part is trapezoidal, and the bottom edge of the inward-folding part is connected to the cover.

[0015] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0016] 1. This technical solution is designed to divide the backing paper into several independent backing paper sheets. Users can peel off individual backing paper sheets as needed for partial pasting, while the remaining backing paper sheets remain covered on the pasting layer, avoiding complete exposure of the pasting layer. This improves the controllability and accuracy of book cover pasting, and is convenient and easy to use.

[0017] 2. The tear line design of this technical solution creates corner protectors at the four corners of the protective film. After being torn off, the corner protectors can be pasted onto the corners of the book's inner pages to prevent the book's corners from bending and curling. Attached Figure Description

[0025] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1:

[0027] Combination Figure 1 and Figure 6 A book cover includes a protective film 1, an adhesive layer 2, and a backing paper 3. The adhesive layer 2 is provided on one side of the protective film 1, that is, the upper surface of the protective film 1 is coated with glue, so that the adhesive layer 2 is formed on the surface of the protective film 1. The backing paper 3 is then adhered and covered on the adhesive layer 2. The backing paper 3 is used to prevent the adhesive layer 2 from being exposed. When in use, the backing paper 3 is peeled off to allow the adhesive layer 2 to be pasted on the book, so that the protective film 1 can be pasted on the book and protect the surface of the book.

[0028] like Figure 1 The base paper 3 has several tear lines 4, which divide the base paper 3 into several base paper pieces 5; the user can tear off the corresponding base paper pieces 5 one by one along the tear lines 4.

[0029] Tear line 4, also known as easy-tear line, is an existing technology. It is a discontinuous weak line processed on the material through mechanical indentation, drilling or laser processing, which allows the material to be torn by hand along this line.

[0030] Combination Figures 1-3 The backing paper 5 includes: backing paper 1 6, backing paper 2 7, and backing paper 3 8; backing paper 1 6, backing paper 2 7, and backing paper 3 8 are all rectangular in shape. Backing paper 1 6 covers the left half of the protective film 1, backing paper 2 7 covers the middle of the protective film 1, and backing paper 3 8 covers the right half of the protective film 1. When using it, backing paper 2 7, backing paper 1 6, and backing paper 3 8 are peeled off in sequence. The backing paper 5 is peeled off in stages, without having to peel it off completely, which makes it convenient to stick the protective film 1 onto the book.

[0031] Combination Figures 1-3Alignment lines 9 are provided on the base paper 3 8. Alignment lines 9 and the side edge of the base paper 3 8 near the base paper 2 7 form a positioning area 10. The positioning area 10 is a rectangular frame. The positioning area 10 is used for the placement and alignment of the book. When in use, the book is placed in the positioning area 10 so that the left side of the book (i.e. the edge of the spine) is aligned with the left side edge of the base paper 3 8 (i.e. the side edge of the base paper 3 8 near the base paper 2 7), the top of the book is aligned with the alignment line 9 located at the top of the base paper 3 8, and the bottom of the book is aligned with the alignment line 9 located at the bottom of the base paper 3 8.

[0032] The base paper 3 is made of PET material.

[0033] The protective film 1 is made of CPP material.

[0034] Combination Figure 4 and Figure 5 The protective film 1 includes: a spine 11, two cover sections 12, and several inward-folding sections 13. The spine 11 is located in the middle of the protective film 1 and is used to be pasted on the spine of the book. The two cover sections 12 are located on both sides of the spine 11 and are used to be pasted on the front and back of the book, respectively. Several inward-folding sections 13 are located on the edges of the cover sections 12. The cover section 12 located on the left side of the spine 11 has inward-folding sections 13 on its left, upper, and lower sides. The cover section 12 located on the right side of the spine 11 has inward-folding sections 13 on its right, upper, and lower sides.

[0035] The spine 11 is rectangular, the cover 12 is rectangular, and the inward fold 13 is trapezoidal. The bottom edge of the inward fold 13 is connected to the cover 12, that is, the longer bottom edge (i.e., the lower bottom) of the trapezoidal inward fold 13 is integrally formed with the edge of the cover 12.

[0036] The protective film 1 has tear lines 14 at each of its four corners. Tear lines 14 are easy-tear lines. Tear lines 14 make the four corners of the protective film 1 form a corner protector 15. The corner protector 15 is a right triangle. The corner protector 15 is torn off and pasted on the corner of the inner page of the book, namely the inside front cover and inside back cover of the book. This improves the structural strength and deformation resistance of the book corner and prevents the book corner from curling and deforming.

[0037] After the corner protector 15 is torn off, the two adjacent inward-folding parts 13 corresponding to the corner protector 15 are separated, thereby allowing the inward-folding parts 13 to be folded relative to the cover part 12 and pasted onto the inner pages of the book.

[0038] Tear lines 14 are also provided at the four corners of the backing paper 3 corresponding to the protective film 1, which makes it easy to tear off the corner protector 15 directly, and then peel off the backing paper 3 of the corner protector 15. The operation is simple and convenient.

[0039] Combination Figure 4 and Figure 5 Tear lines 16 are provided between the two ends of the spine 11 and the corresponding inward turning parts 13, so that the protective film 1 forms waste parts 17. The waste parts 17 are isosceles trapezoidal in shape. The waste parts 17 are torn off the protective film 1 along the tear lines 16, thereby separating the two ends of the spine 11 and the corresponding inward turning parts 13. Specifically, the upper end of the spine 11 is separated from the inward turning parts 13 at the upper end of the two cover parts 12, and the lower end of the spine 11 is separated from the inward turning parts 13 at the lower end of the two cover parts 12, thereby realizing the folding of the inward turning parts 13 and pasting them on the inner pages of the book; the tear lines 16 are also known as easy-tear lines.

[0040] The specific working process of this solution is as follows: Place the first backing paper 6 and the third backing paper 8 in a left-right orientation, then place the book face up in the positioning area 10 of the third backing paper 8, so that the spine edge of the book is aligned with the edge of the third backing paper 8 near the second backing paper 7, and the top and bottom edges of the book are aligned with the alignment lines 9 of the top and bottom edges of the third backing paper 8, respectively; peel off the second backing paper 7, and paste the spine 11 onto the spine of the book, then peel off the first backing paper 6, and paste the cover 12 on one side of the spine 11 onto the front of the book. On the top, that is, pasted on the cover of the book; turn or flip the book so that the back of the book is no longer pressed on the bottom paper 3 8, then peel off the bottom paper 3 8, and paste the cover part 12 on the other side of the spine part 11 onto the back of the book, that is, paste it onto the back cover of the book; tear off the corresponding corner protector part 15 and waste part 17, flip the inward part 13 and paste it onto the edge of the inner page of the book, that is, paste the inward part 13 onto the edge of the inside front cover and inside back cover of the book; paste the corner protector part 15 onto the corner of the inner page of the book, that is, paste the corner protector part 15 onto the corner of the inside front cover and inside back cover of the book.
