Description

Technical Field

[0001] The present application relates to the technical field of notebooks, and in particular to an easy-to-tear notebook with a circular spine. Background Art

[0002] Notebooks are small booklets commonly used in daily life to record various materials and things. They can be used for writing notes, memorizing things, and making drafts. Handbooks are a special kind of notebooks that people carry with them to record their thoughts, things to do, and things they are afraid of forgetting. Therefore, it is common to tear off paper from handbooks.

[0003] In the related art, notebooks are generally bound together by glue binding or thread binding. The paper of a linear book is generally twice the size of the cover of a linear book. When binding, the paper is folded along the center seam to align the book edges, and the book is covered with covers, punched and threaded. When a thread-bound notebook needs to be torn, the other page of paper formed by the fold will fall off together. Therefore, a glue-bound book includes gauze for pasting paper, and glue is applied on the gauze. One side of several stacked papers is pasted on the gauze to form the spine. A cover is also provided on the outside of the glue-bound book, and the cover is fixedly connected to the gauze at both ends along the thickness direction of the book.

[0004] Regarding the above-mentioned related technologies, the gauze is provided to facilitate the bending of the spine when flipping through the notebook, but the inner pages of the notebook bound in this way are difficult to tear off and the paper is easily damaged when tearing off. Summary of the invention

[0005] In order to facilitate tearing off inner pages without affecting the use of other notebooks or other inner pages, the present application provides an easy-tear notebook with a circular spine.

[0006] The present application provides a tear-away notebook with a circular spine adopts the following technical solution:

[0007] A tearable notebook with an arc spine comprises inner pages, wherein a plurality of inner pages are stacked along the thickness direction thereof to form an inner core, a glue layer is pasted and fixed on one side in the width direction of the inner core, a cover made of a flexible material is arranged outside the inner core, the width direction of the cover is parallel to the length direction of the inner core, a middle part of the cover is pasted and fixed to one side in the width direction of the inner core by a glue layer to form a spine, the cross section of the spine is an arc shape, and the glue layer is a PVA glue layer.

[0008] By adopting the above technical solution, the side edges of the inner pages are fixed to the cover made of flexible material through the glue layer, and each inner page is not connected to each other. The side edge of the inner page in the width direction is glued with PVA glue, which helps to reduce the possibility of the glue overflowing to the side of the inner page in the thickness direction during the drying process. In this way, the user can easily tear off a single page or multiple pages of inner pages without affecting the use of other inner pages. At the same time, tearing off the inner pages will cause the inner core to become thinner, and the cover made of flexible material can better adapt to the inner core of different thicknesses, which is convenient to use. The arc-shaped spine and the cover made of flexible material can make the inner pages on both sides of the spine present a larger angle, so that the covers on both sides of the spine are in contact. This arrangement allows the user to place the notebook on the bottom surface at any angle when writing.

[0009] Preferably, a plastic protective skin is provided on the outer side of the cover, and the plastic protective skin is wrapped around a side of the cover close to the glue layer along the width direction of the inner core.

[0010] By adopting the above technical solution, the plastic protective skin has a higher hardness than the soft cover, which helps to protect the soft cover and reduce the possibility of damaging the cover and / or the glue layer during use.

[0011] Preferably, two of the plastic protective skins are arranged at intervals along their own thickness direction, an embedding groove is formed between the two plastic protective skins, a ruler is arranged in the embedding groove, the ruler slides with the embedding groove along the length direction of the inner core, the embedding groove is closed on both sides along the width direction of the inner core, the embedding groove is open on the upper side along the length direction of the inner core, and the other side is closed.

[0012] By adopting the above technical solution, the user can use the ruler to measure or tear the torn inner pages into smaller pieces, so that the torn pieces have neat edges, which are beautiful and practical. At the same time, the ruler has a higher hardness than the cover and the plastic protective cover, which helps to further protect the spine of the book.

[0013] Preferably, a lace is formed on one side of the ruler in the width direction.

[0014] By adopting the above technical solution, different laces can change the edge of the smaller inner page torn by the user using the ruler, which has a higher aesthetics and helps to improve the practicality of the ruler in this way.

[0015] Preferably, an inclined surface is formed in the width direction of the ruler, and the inclined surface is inclined from the middle of the ruler to the edge along the width direction of the ruler, so that the ruler gradually becomes thinner from the middle to the edge.

[0016] By adopting the above technical solution, the gradually thinning inclined surface is easier to press on the paper, providing a stable reference edge, making paper tearing more controllable and not easy to deviate from the edge of the inclined surface, so that the torn paper has a clear and definite edge.

[0017] Preferably, one ruler is provided on each side of the inner core in the thickness direction.

[0018] By adopting the above technical solution, two rulers are wrapped around the sides of the notebook spine to protect the spine.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-5 This application is described in further detail.

[0034] The embodiment of the present application discloses an easy-tear notebook with a circular spine.

[0035] See also Figure 1-Figure 3The tear-away notebook with a circular spine includes inner pages 31, which are stacked in a vertical direction and form an inner core 3. The outer side of the inner core 3 in the length direction is wrapped with a cover 1, which is made of a flexible material. In this embodiment, the cover 1 is made of a PU leather material, and both sides of the cover 1 in the thickness direction are formed with a smooth surface. After the cover 1 is unfolded, the middle part of the cover 1 in the length direction is coated with a glue layer 2, and the glue layer 2 is coated with PVA glue. After the glue layer 2 is half dry, one side of the inner core 3 in the width direction is attached to the glue layer 2. The inner pages 31 arranged in the above manner are complementary to each other, and the use of PVA glue to paste the inner pages 31 and the cover 1 helps to reduce the possibility of the glue overflowing to the two sides of the inner page 31 in the thickness direction during the drying process. When the user tears off the inner page 31, the side of the inner page 31 is separated from the entire glue layer 2, thereby ensuring that the user can easily tear off a single page or multiple pages of the inner page 31. After tearing off multiple inner pages 31, the inner core 3 will gradually become thinner, and if other stationery is inserted into the notebook, the inner core 3 will become thicker. The cover 1 made of soft material can better wrap around the outer side of the inner core 3 of different thicknesses to protect the inner core 3. At the same time, the PU leather has good ductility, and the user can turn over the inner core 3 so that the two adjacent inner pages 31 are 180 degrees, achieving barrier-free writing and helping to improve the fluency of writing.

[0036] A circular chamfer 32 is formed on the side of any inner page 31 away from the adhesive layer 2 along its own width direction. One circular chamfer 32 is provided on each side of the inner page 31 in the length direction, and the two chamfers 32 are symmetrically arranged.

[0037] The cover 1 includes a front cover 11, an edge seal 13 and a back cover 12. The front cover 11 is located on the upper side of the inner core 3 in the thickness direction, the back cover 12 is located on the lower side of the inner core 3 in the thickness direction, the edge seal 13 is located on the side of the inner core 3 along its own width direction close to the adhesive layer 2, and the adhesive layer 2 is coated on the side surface of the edge seal 13 close to the inner core 3. The cross section of the contact position between the edge seal 13 and the inner core 3 is arc-shaped, forming an arc-shaped spine. Compared with the general square spine, the spine set in this way and the edge seal 13 made of flexible material can make the inner pages 31 on both sides of the spine have a large angle after the notebook is opened, and can be opened to the side of the two covers 11 away from the inner core 3 and the side of the back cover 12 away from the inner core 3. When writing, the user can open the notebook to any angle, so that the notebook can be attached to the desktop or other surface, which is convenient for writing.

[0038] The side of the back cover 12 away from the edge seal 13 extends outward and is formed with a rim 14, which passes over one side of the inner core 3 in the width direction and covers the upper side of the cover 11. A magnetic block 4 is arranged inside the rim 14 along its own width direction away from the back cover 12, and a corresponding magnetic block 4 is also arranged inside the cover 11. When the user puts the notebook on, the rim 14 will be wrapped on the corresponding side of the inner core 3 in the width direction, and the two magnetic blocks 4 correspond, and the rim 14 is adsorbed on the cover 11. In this way, the inner core 3 is completely wrapped around the width direction, which helps to improve the protection effect of the inner core 3 and improve the service life of the entire notebook.

[0039] See also Figure 1-Figure 5 A plastic protective skin 15 is also fixed on the outer side of the cover 1. The plastic protective skin 15 is wrapped around the edge seal 13, the front cover 11 near the edge seal 13, and the back cover 12 near the edge seal 13. Two plastic protective skins 15 are arranged at intervals along the thickness direction of the plastic protective skins 15. An embedding groove 16 is formed between the two plastic protective skins 15. The embedding groove 16 is closed on both sides along the width direction of the inner core 3, the embedding groove 16 is closed on the lower side along the length direction of the inner core 3, and the embedding groove 16 is open on the upper side along the length direction of the inner core 3. A ruler 5 is arranged in the embedding groove 16, and the ruler 5 slides in the embedding groove 16 along the length direction of the inner core 3. When in use, the user can pull the ruler 5 out of the embedding groove 16. Inclined surfaces 51 are formed on both sides of the ruler 5 in the width direction. The two inclined surfaces 51 are inclined along the sides close to each other in the width direction of the ruler 5 to the sides away from each other, so that the middle part of the ruler 5 gradually becomes thinner toward the edge. The thinner edge can provide a better guide when the user tears the paper, and the gradually thinning inclined surface 51 is easier to press on the paper, making the action of tearing the paper more controllable, and the torn paper has a clear and definite edge.

[0040] One ruler 5 is provided on each side of the inner core 3 in the thickness direction. The ruler 5 has a higher hardness than the soft cover 1. Two rulers 5 are wrapped on the two sides of the notebook spine to provide support for the spine. When the user places the notebook casually, the ruler 5 can make the spine have a certain bending resistance, which helps to reduce the possibility of other objects or external forces causing the spine to bend to one side, and helps to further protect the notebook.

[0041] Any one side of the ruler 5 in the width direction may be formed with a lace 52. In this embodiment, see Figure 5 One of the rulers 5 has a wavy edge on one side in the width direction and a folded edge on the other side. The user pulls the ruler 5 out of the embedding slot 16, presses it on the torn inner page 31, and tears the inner page 31 into smaller pieces along one edge of the ruler 5.

[0042] A plastic sheet 141 is also fixed on one side of the edge 14 close to the inner core 3. Two plastic sheets 141 are arranged at intervals along the thickness direction of the edge 14. An embedding groove 142 is formed between the two plastic sheets 141. Both sides of the embedding groove 142 along the width direction of the plastic sheet 141 are closed. The lower end of the embedding groove 142 along the length direction of the inner core 3 is closed, and the upper end of the embedding groove 142 along the length direction of the inner core 3 is open. The ruler 5 can also slide into the embedding groove 142 along the length direction of the inner core 3. The user can adjust the position of the ruler 5 on the cover 1 at will, thereby changing the protective effect of the ruler 5 on the notebook.

[0043] The implementation principle of the easy-to-tear notebook with a circular spine in the embodiment of the present application is as follows: during production, the staff applies PVA glue on the edge seal 13 of the cover 1. When the PVA glue is half dry, one side of the inner core 3 stacked with multiple inner pages 31 in the width direction is attached to the edge seal 13. When in use, the user can completely tear off any inner page 31. The cover 1 and the plastic protective skin 15 wrapped around the outer side of the inner core 3 help protect the inner core 3, and the ruler 5 that can be removed and repositioned not only improves the practicality of the notebook, but also helps protect the entire notebook and helps to increase the service life of the notebook.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
