[0052] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0053] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0056] Existing stationery packaging boxes, especially those used to package pencils, brushes, pencil sharpeners, and other accessories, are mostly rectangular plastic boxes. These accessories are stored inside. The lack of effective internal structures to secure these accessories makes them prone to collision and friction during transport, leading to damage or scratches. Furthermore, rectangular plastic boxes are not only more expensive to manufacture but also difficult to recycle. Improper disposal of these boxes can also pollute the environment.

[0057] To solve the above problems, such as Figures 1-3 As shown, this embodiment provides a stationery packaging box. The stationery packaging box includes an outer shell 100, a support tray 200, and a clamping liner 300. The outer shell 100 has a first receiving cavity 101. The support tray 200 is disposed in the first receiving cavity 101 and has a supporting space 203. The clamping liner 300 is installed in the supporting space 203. The clamping liner 300 is provided with a first clamping part 301, a second clamping part 302, and a third clamping part 303. The first clamping part 301, the second clamping part 302, and the third clamping part 303 can each individually clamp and fix a stationery item. The outer shell 100, the support tray 200, and the clamping liner 300 are all individually folded from paper material.

[0058] The stationery packaging box, by providing a first receiving cavity 101 within the outer shell 100, can accommodate and fix the tray 200 within the first receiving cavity 101. Combined with the supporting space 203 within the tray 200, the clamping liner 300 is installed within the supporting space 203. The clamping liner 300 is provided with a first clamping part 301, a second clamping part 302, and a third clamping part 303, allowing each of the first clamping part 301, the second clamping part 302, and the third clamping part 303 to individually clamp and fix one type of stationery. Stable clamping and fixing of three types of stationery on the clamping liner 300 is achieved. Moreover, the outer shell 100 and the support tray 200 jointly package and protect each piece of stationery, resulting in good packaging effect and solving the problem of collision between stationery items during subsequent transportation, thus improving the protection of stationery. By making the outer shell 100, support tray 200 and clamping liner 300 all made of paper material and folded separately, not only can production costs be reduced, but recycling can also be facilitated, reducing the difficulty of recycling and improving environmental protection.

[0059] It should be noted that, in this embodiment, the stationery includes a pencil, a brush, and a pencil sharpener. The first clamping part 301 is used to clamp and fix the pencil, the second clamping part 302 is used to clamp and fix the brush, and the third clamping part 303 is used to clamp and fix the pencil sharpener.

[0060] like Figure 1 and Figure 4 As shown, the outer shell 100 is formed by folding a first plate 1. The first plate 1 includes a first bent plate 11, a second bent plate 12, a third bent plate 13, a fourth bent plate 14 and a fifth bent plate 15 connected in sequence along a first direction. The first bent plate 11, the second bent plate 12, the third bent plate 13 and the fourth bent plate 14 are folded in sequence along the connection direction, and the fifth bent plate 15 is fixedly connected to the first bent plate 11. By configuring the first sheet material 1 into a series of sequentially connected bent plates 11, 12, 13, 14, and 15, and then folding the first bent plates 11, 12, 13, and 14 along the connecting direction to fix the fifth bent plate 15 to the first bent plate 11, the first sheet material 1 can be folded into a cylindrical outer shell 100. This allows the hollow hole in the cylindrical structure to form a first receiving cavity 101. Furthermore, the openings at both ends of the hollow hole facilitate the entry and exit of the tray 200 into the first receiving cavity 101. The structure is simple and easy to assemble. It should be noted that in this embodiment, the first bent plate 11 and the fifth bent plate 15 are bonded and fixed together.

[0061] In actual sales, to facilitate the display of the stationery packaging box, the outer shell 100 is provided with a hanging part 102, which can be hung and fixed on a hook. Specifically, the hanging part 102 is provided with a hanging hole 1021, into which the hook can extend.

[0062] In this embodiment, as Figure 4 As shown, the fourth bending plate 14 is provided with a first outward folding part 141, and the first outward folding part 141 is provided with a hanging hole 1021. When the first plate 1 is folded into the outer shell 100, the first outward folding part 141 folds outward and forms a hanging part 102.

[0063] Combination Figure 2 The specific structure of the pallet 200 is described below. The pallet 200 includes a pallet body 201 and a surrounding frame structure 202. The pallet body 201 can support the clamping liner 300. The surrounding frame structure 202 is connected to the edge of the pallet body 201. The surrounding frame structure 202 and the pallet body 201 together form a supporting space 203. An insertion groove is provided between the surrounding frame structures 202. An insertion protrusion 304 is provided on the clamping liner 300. The insertion protrusion 304 is inserted and fixed into the insertion groove. By disassembling the pallet 200 into a pallet body 201 and a surrounding frame structure 202 connected to the edge of the pallet body 201, the pallet body 201 and the surrounding frame structure 202 together form a support space 203. The pallet body 201 supports the clamping liner 300, and an insertion groove is provided between the pallet body 201 and the surrounding frame structure 202. The insertion protrusion 304 on the clamping liner 300 is inserted and fixed into the insertion groove, so as to realize the assembly and fixation of the clamping liner 300 and the pallet 200.

[0064] In this embodiment, the pallet 200 is formed by folding the second plate 2. The second plate 2 includes a sixth bent plate 21, a seventh bent plate 22, and an eighth bent plate 23. The sixth bent plate 21 is connected to the seventh bent plate 22 on both sides along the first direction, and the sixth bent plate 21 is connected to the eighth bent plate 23 on both sides along the second direction. The sixth bent plate 21 constitutes the pallet body 201. The two seventh bent plates 22 and the two eighth bent plates 23 are folded relative to the sixth bent plate 21 and form a frame structure 202. By connecting the seventh bending plate 22 to both sides of the sixth bending plate 21 along the first direction, and connecting the eighth bending plate 23 to both sides of the sixth bending plate 21 along the second direction, the sixth bending plate 21 serves as the pallet body 201. The seventh bending plate 22 and the eighth bending plate 23 are folded relative to the sixth bending plate 21, so that the seventh bending plate 22 and the eighth bending plate 23 together form the frame structure 202, thus realizing the folding and forming of the pallet 200.

[0065] As an optional solution, the frame structure 202 includes two horizontal plates 2021 arranged opposite each other along a first direction and two vertical plates 2022 arranged opposite each other along a second direction. The two horizontal plates 2021 are respectively connected to the two sides of the sixth bending plate 21 along the first direction. Each horizontal plate 2021 extends along the second direction. Each seventh bending plate 22 can be folded into a horizontal plate 2021. The two vertical plates 2022 are respectively connected to the two sides of the sixth bending plate 21 along the second direction. Each vertical plate 2022 extends along the first direction. Each eighth bending plate 23 can be folded into a vertical plate 2022. By splitting the frame structure 202 into two horizontal plates 2021 arranged opposite each other along the first direction and two vertical plates 2022 arranged opposite each other along the second direction, each seventh bending plate 22 can be folded into a horizontal plate 2021 and each eighth bending plate 23 can be folded into a vertical plate 2022. The horizontal plates 2021 and vertical plates 2022 can be folded separately and assembled together, reducing the assembly difficulty of the frame structure 202.

[0066] Specifically, the seventh bending plate 22 includes a first bending portion 221, a second bending portion 222, a third bending portion 223, and a fourth bending portion 224. The first bending portion 221 is connected to the sixth bending plate 21 along the first direction on one side along the first direction. The second bending portion 222 is connected to the first bending portion 221 along the first direction on one side along the first direction on the other side along the first direction. The third bending portion 223 is connected to the second bending portion 222 along the first direction on one side along the first direction on the other side along the first direction. The fourth bending portion 224, the third bending portion 223, the second bending portion 222, and the first bending portion 221 are bent sequentially and formed into a horizontal plate 2021. When the seventh bent plate 22 needs to be folded into a horizontal plate 2021, the fourth bent portion 224, the third bent portion 223, the second bent portion 222, and the first bent portion 221 are folded sequentially towards the direction of the sixth bent plate 21, so that the fourth bent portion 224 can abut against the sixth bent plate 21. Then, glue is used to bond and fix the fourth bent portion 224 to the sixth bent plate 21, completing the assembly of the horizontal plate 2021. It should be noted that in this embodiment, a notch is provided between the second bent portion 222 and the third bent portion 223. When the seventh bent plate 22 is folded into a horizontal plate 2021, the notch forms an insertion groove that engages with the insertion protrusion 304 inside the clamping liner 300.

[0067] To facilitate the assembly of the horizontal plate 2021 and the vertical plate 2022, the seventh bending plate 22 also includes a fifth bending portion 225, wherein the first bending portion 221 is connected to the fifth bending portion 225 on both sides along the second direction, and the fifth bending portion 225 can be bent relative to the first bending portion 221 and fixedly connected to the vertical plate 2022.

[0068] Furthermore, the seventh bending plate 22 also includes a sixth bending portion 226, wherein the third bending portion 223 is connected to the sixth bending portion 226 on both sides along the second direction. When the two seventh bending plates 22 are folded into two horizontal plates 2021 respectively, the two sixth bending portions 226 located on the same side along the second direction within the two seventh bending plates 22 can be inserted and fixed together. By connecting the sixth bending portions 226 on both sides along the second direction of the third bending portion 223 respectively, when the seventh bending plates 22 located at both ends of the sixth bending plate 21 along the first direction are folded into two horizontal plates 2021 respectively, the two sixth bending portions 226 located on the same side along the second direction within the two seventh bending plates 22 are inserted and fixed together, thereby further improving the overall structural cavity bottom of the frame structure 202.

[0069] It should be noted that in this embodiment, the two sixth bends 226 located on the same side along the first direction within the two seventh bends 22 form a set of insertion structures. The two sixth bends 226 within each set of insertion structures are provided with insertion notches 2261 at the same end along the first direction. When the two seventh bends 22 are folded and formed respectively, the two sixth bends 226 insertion notches 2261 within each set of insertion structures can be inserted and fixed together.

[0070] In an optional embodiment, the eighth bending plate 23 includes a seventh bending portion 231, an eighth bending portion 232, a ninth bending portion 233, and a tenth bending portion 234. The two sides of the seventh bending portion 231 along the second direction are respectively connected to one side of the sixth bending plate 21 along the second direction and one side of the eighth bending portion 232 along the second direction. The other half of the eighth bending portion 232 along the second direction is connected to the ninth bending portion 233. The other side of the ninth bending portion 233 along the second direction is connected to the tenth bending portion 234. When the eighth bending plate 23 needs to be folded into the longitudinal plate 2022, the tenth bending part 234, the ninth bending part 233, the eighth bending part 232 and the seventh bending part 231 are folded sequentially along the second direction towards the end near the sixth bending plate 21, so that the tenth bending part 234 abuts against the sixth bending plate 21 and the ninth bending part 233 abuts against the fifth bending part 225. Then, glue is used to bond and fix the tenth bending part 234 to the sixth bending plate 21 and the ninth bending part 233 to the fifth bending part 225, thus completing the assembly and fixing of the transverse plate 2021 and the longitudinal plate 2022.

[0071] like Figure 6As shown, the clamping liner 300 is formed by folding the third plate 3. The third plate 3 includes a ninth bent plate 31, a tenth bent plate 32, and an eleventh bent plate 33. Any one of the three plates 31, 32, and 33 is simultaneously connected to the other two. The ninth bent plate 31 can be folded into the first clamping part 301, the tenth bent plate 32 can be folded into the second clamping part 302, and the eleventh bent plate 33 can be folded into the third clamping part 303.

[0072] It should be noted that, in this embodiment, the ninth bending plate 31 is connected to the tenth bending plate 32 along one side of the first direction and to the eleventh bending plate 33 along one side of the second direction. The tenth bending plate 32 is connected to the eleventh bending plate 33 along one end of the first direction, so that the eleventh bending plate 33 is simultaneously connected to the ninth bending plate 31 and the tenth bending plate 32 along the same side of the first direction.

[0073] Specifically, such as Figure 6 As shown, the ninth bending plate 31 includes an eleventh bending portion 311, a twelfth bending portion 312, and a thirteenth bending portion 313. The eleventh bending portion 311 is connected to the tenth bending plate 32 along one side of the first direction, and is connected to the twelfth bending portion 312 along the other side of the first direction. The eleventh bending portion 311 is connected to the eleventh bending plate 33 along one side of the second direction, and is connected to the thirteenth bending portion 313 along the other side of the second direction. During assembly, the twelfth bend 312 and the thirteenth bend 313 are folded relative to the eleventh bend 311, and the tenth bend plate 32 and the eleventh bend plate 33 are used to form the first clamping part 301. At this time, the first clamping part 301 has a first clamping area with a clamping opening. The pencil can be placed into the first clamping area along the clamping opening. When the clamping liner 300, the support tray 200 and the outer shell 100 are assembled together, the outer shell 100 can block the clamping opening to clamp and fix the pencil separately at the first clamping part 301.

[0074] The tenth bending plate 32 includes a fourteenth bending portion 321, a fifteenth bending portion 322, a sixteenth bending portion 323, a seventeenth bending portion 324, an eighteenth bending portion 325, and a nineteenth bending portion 326 connected sequentially along a first direction. The fourteenth bending portion 321 is connected to the eleventh bending portion 311. The fourteenth bending portion 321 is folded upward relative to the eleventh bending portion 311. The fifteenth bending portion 322 is folded downward relative to the fourteenth bending portion 321. The sixteenth bending portion 323 is folded downward relative to the fifteenth bending portion 322. The seventeenth bending portion 324 is folded upward relative to the sixteenth bending portion 323. The eighteenth bending portion 325 is folded upward relative to the seventeenth bending portion 324. The nineteenth bending portion 326 is folded downward relative to the eighteenth bending portion 325. The nineteenth bending portion 326 forms an insertion protrusion 304 for clamping the inner liner 300.

[0075] By folding the tenth bending plate 32 as described above, an S-shaped wave structure can be formed. Combined with the two first cutting grooves 327 extending in the first direction at intervals along the second direction on the sixteenth bending portion 323, the seventeenth bending portion 324 and the eighteenth bending portion 325, a snap ring located at the trough of the wave structure can be formed on the second clamping portion 302 to snap and fix the brush in the snap ring at the trough of the wave structure, thereby realizing the clamping and fixing of the brush in the second clamping portion 302.

[0076] The eleventh bending plate 33 includes a twentieth bending portion 331, a twentieth bending portion 332, a twentieth bending portion 333, and a twentieth bending portion 334 connected sequentially along the second direction. The twentieth bending portion 331 is connected to the eleventh bending portion 311. The twentieth bending portion 331 is folded upward relative to the eleventh bending portion 311. The twentieth bending portion 332 is folded downward relative to the twentieth bending portion 331. The twentieth bending portion 333 is folded downward relative to the twentieth bending portion 332. The twentieth bending portion 334 is folded upward relative to the twentieth bending portion 333, so that the eleventh bending plate 33 is folded into an arched structure. A second cutting groove 3321 is opened at the upper end of the arched structure, i.e., the twentieth bending portion 332, so that a receiving space can be formed in the arched structure to place a pencil sharpener into the receiving space.

[0077] It should be noted that, in this embodiment, the twenty-third bend 334 can be inserted into the gap between the pallet body 201 and the longitudinal plate 2022 to further improve the connection between the clamping liner 300 and the pallet 200.

[0078] In addition, to facilitate the insertion and fixing of the liner 300 and the support tray 200, a third cutting groove 3322 is provided on the 23rd bend 334.
