[0002] In daily study and office work, to protect the appearance of paper products such as books and notebooks and extend their lifespan, they are often wrapped in book covers. Traditional book covers are mainly divided into two types: one is a prefabricated cover, and the other is a self-adhesive cover that can be cut and pasted.

[0003] Self-adhesive book covers are widely popular due to their ease of use and wide range of applications. These covers typically consist of a base material, an adhesive layer applied to the base material, and a release material layer covering the adhesive layer. To use, the user removes the release material to expose the adhesive layer, then adheres the cover to the cover and edges of the book to protect it.

[0004] In the prior art, release paper is a commonly used release material. However, release paper has certain drawbacks in actual use. For example, during the removal process, due to the brittleness of the release paper or uneven adhesion to the glue layer, it is prone to breakage and tearing, making it impossible to completely peel it off in one go. Furthermore, removing the remaining torn parts is often cumbersome, affecting the user experience. Therefore, there is an urgent need to provide a self-adhesive book cover with a reasonable structure and convenient use. Utility Model Content

[0044] In the present invention, the surface of the release film 3 is provided with a release coating, which is one of silicone oil coating, fluorine coating or non-silicone release agent. The glue layer 2 is one of hot melt adhesive, pressure sensitive adhesive or water-based adhesive.

[0045] In the present invention, the thickness of the release film 3 is between 0.01 mm and 0.20 mm, which ensures sufficient strength to avoid tearing, but is not too thick to affect the convenience of operation.

[0046] In the present invention, a plurality of separating lines 4 are provided on the release film 3, which divide the release film 3 into a plurality of independently tearable areas, making it convenient for users to perform the pasting operation step by step, avoiding the inconvenience caused by one-time tearing, and reducing the risk of the glue layer 2 being contaminated during use.

[0047] Specifically, the release film 3 is divided into a spine release film 31, a cover inner release film 32 and a cover outer release film 33 by a dividing line 4, wherein two cover inner release films 32 and two cover outer release films 33 are each provided, the spine release film 31 is located in the middle of the spine covering sheet 13, the two cover inner release films 32 are respectively located on the left and right sides of the spine covering sheet 13, and the two cover inner release films 32 are respectively located on the first cover covering sheet 11 and the spine covering sheet 13 and on the second cover covering sheet 12 and the spine covering sheet 13, and the two cover outer release films 33 are respectively located on the first cover covering sheet 11 and the second cover covering sheet 12 and on the outside of the cover inner release film 32.

[0048] When using, first tear off the spine release film 31, stick the spine covering sheet 13 in the adhesive film 1 to the spine of the book for positioning, then tear off one of the cover inner release films 32, so that the adhesive film 1 is stuck to the spine and cover of the book, then tear off the other cover inner release film 32, so that the adhesive film 1 is stuck to the spine and cover of the book, and finally tear off the two cover outer release films 33, so that the adhesive film 1 is stuck to the corresponding cover.

[0049] like Figure 3 As shown, in order to facilitate tearing of the spine release film 31, the cover inner release film 32 and the cover outer release film 33, tearable sheets 34 are integrally formed on the edges of the spine release film 31, the cover inner release film 32 and the cover outer release film 33.

[0050] Furthermore, the tear-off piece 34 on the spine release film 31 is located on one side edge facing one of the cover inner release films 32 and is located on the upper side of the cover inner release film 32, the tear-off piece 34 on the cover inner release film 32 is located on one side edge facing the adjacent cover outer release film 33 and is located on the upper side of the cover outer release film 33, and the tear-off piece 34 on the cover outer release film 33 is located on one of its side edges that is not adjacent to the cover outer release film 33. The easy-tear sheet 34 arranged in this way, the easy-tear sheet 34 on the release film 31 at the spine and the easy-tear sheet 34 on the inner release film 32 at the cover will not be exposed outside the edge of the adhesive film 1, and only the easy-tear sheet 34 on the outer release film 33 at the cover is exposed, which is more beautiful and reduces the space occupied. Since the spine release film 31 is torn off first when the utility model is used, the easy-tear sheet 34 on the spine release film 31 can be arbitrarily set on the side edge facing one of the inner release films 32 at the cover, and the easy-tear sheet 34 on the cover The easy-tear piece 34 on the inner release film 32 is located on the edge of one side facing the adjacent outer release film 33 at the cover, and cannot face the release film 31 at the spine. This is because if the easy-tear piece 34 on the inner release film 32 at the cover faces the release film 31 at the spine, it will stick to the glue layer 2 after the release film 31 at the spine is torn off, and cannot play the role of the easy-tear piece 34. Similarly, the outer release film 33 at the cover is torn off last, so the easy-tear piece 34 on it must be located on one of its side edges that is not adjacent to the outer release film 33 at the cover.

[0051] In the present invention, an upper inner wrapping sheet 14, a lower inner wrapping sheet 15, and a side inner wrapping sheet 16 are integrally formed on the edges of the first and second cover sheets 11, 12. The upper inner wrapping sheet 14 and the lower inner wrapping sheet 15 are located on the upper and lower sides of the first and second cover sheets 11, 12, respectively. The side inner wrapping sheet 16 is located on the side of the first and second cover sheets 11, 12 away from the spine wrapping sheet 13. When in use, the first and second cover sheets 11, 12 are adhered to the upper and lower inner sides of the book cover, while the side inner wrapping sheet 16 is adhered to the inner side of the book cover away from the spine.

[0052] The side of the adhesive film 1 away from the glue may have a frosted effect to prevent slipping.

[0053] The release film 3 may be colored or transparent; any single-color or color graphics may be printed on the release film 3; and the surface of the release film 3 may be matte / smooth or textured.

[0054] It should also be pointed out that the terms indicated in the present invention, such as: "front", "rear", "vertical", "horizontal", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as limiting the scope of protection of the present invention.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
