[0030] The embodiments will be described in detail below in conjunction with the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0031] Reference Figures 1 to 7 , the embodiment of the present application provides a packaging box structure 100 with a display function, and the packaging box structure 100 includes an outer box 10 and an inner box 20. The outer box 10 is provided with an opening 11 at one end along the first direction X. The inner box 20 is arranged in the outer box 10 through the opening 11 and can be pulled out and flipped relative to the outer box 10 in a fully pulled out state to switch from a fully pulled out state to a display state. The inner box 20 is provided with an opening 21 on one side along the second direction Y, and the inner box 20 includes a first inner wall portion 22 arranged opposite to the opening 21 along the second direction Y, and the second direction Y intersects with the first direction X. The outer box 10 includes a first outer wall portion 12, the first outer wall portion 12 is away from the opening 21 along the second direction Y, and is recessed inwardly in the opening 11 along the first direction X. In the display state, the first inner wall portion 22 abuts against the first outer wall portion 12. An additional layer plate 23 is disposed on the outer side of the first inner wall portion 22 away from the opening 21 . When the inner box 20 is in a closed state, the additional layer plate 23 is connected to the first outer wall portion 12 along the first direction X and is flush with each other.

[0032] The inner box 20 is similar to a drawer structure. The inner box 20 can be pushed into the outer box 10 through the opening 11, and can also be pulled out to the outside of the outer box 10 through the opening 11. The end of the inner box 20 adjacent to the opening 11 in the closed state is its outer end, and the end away from the opening 11 is its inner end. The outer end of the inner box 20 forms a pull-out end that is convenient for pull-out and flip-over operations, and the inner end of the inner box 20 forms a pivot end that can be pivotally connected to the outer box 10.

[0033] The fully withdrawn state of the inner box 20 refers to the state in which the inner box 20 is withdrawn the maximum distance from the outer box 10. Optionally, in order to facilitate the flipping of the inner box 20, the inner box 20 does not separate from the outer box 10 when in the fully withdrawn state, but is rotatably connected to the outer box 10. In other words, in the fully withdrawn state, the inner box 20 is pivotally connected to the outer box 10.

[0034] The opening 21 of the inner box 20 can be used for taking, placing and displaying products. The first inner wall portion 22 is arranged opposite to the opening 21. If the opening 21 is formed at the top of the inner box 20, the first inner wall portion 22 is the bottom wall of the inner box 20.

[0035] The first outer wall portion 12 is away from the opening 21 along the second direction Y when the inner box 20 is in a closed state. When the inner box 20 is in a closed state, the first inner wall portion 22 and the first outer wall portion 12 are arranged opposite and adjacent to each other. Optionally, if the first inner wall portion 22 is the bottom wall of the inner box 20, the first outer wall portion 12 is the bottom wall of the outer box 10.

[0036] It should be noted that, unless otherwise specified or explained, the orientation and position relationship of the embodiments of the present application are all referred to when the inner box 20 is in a closed state, and will not be elaborated on later.

[0037] The first outer wall portion 12 is recessed inwardly into the opening 11 along the first direction X, which means that the first outer wall portion 12 is located inside the opening 11 along the first direction X and is spaced apart from the opening 11 , and a clearance space is formed between the first outer wall portion 12 and the opening 11 .

[0038] In the closed state, the first inner wall portion 22 and the first outer wall portion 12 are arranged opposite and adjacent to each other. In the display state, the first inner wall portion 22 abuts against the first outer wall portion 12. In order to improve the stability of the inner box 20 in the display state and a better product display angle, the inner box 20 can be tilted relative to the second direction Y in the display state. In other words, the first inner wall portion 22 abuts against the first outer wall portion 12 at an obtuse angle, and the turning angle of the inner box 20 from the fully withdrawn state to the display state is an obtuse angle.

[0039] The outer surface of the first inner wall portion 22 facing away from the opening 21 may be a frosted surface or a rough surface to improve the stability of the abutment between the first inner wall portion 22 and the first outer wall portion 12, thereby improving the stability of the inner box 20 in the display state.

[0040] In the first direction X, the layer adding plate 23 may be adjacent to the outer end of the first inner wall portion 22 so as to cooperate with the first outer wall portion 12. When the inner box 20 is in a closed state, the layer adding plate 23 is connected to the first outer wall portion 12 along the first direction X. At this time, the first outer wall portion 12 and the layer adding plate 23 may jointly form a side portion of the packaging box structure 100 along the second direction Y.

[0041] In some examples, the outer surface of the layer-adding plate 23 is flush with the outer surface of the first outer wall portion 12. In other examples, the thickness of the layer-adding plate 23 and the first outer wall portion 12 are the same, and the two are flush as a whole.

[0042] The layering plate 23 may be connected to the first inner wall portion 22 by bonding or other suitable means.

[0043] The packaging box structure 100 provided in the embodiment of the present application includes an outer box 10 and an inner box 20 that can be pulled out and arranged in the outer box 10 through the opening 11 of the outer box 10. When the inner box 20 is closed, its opening 21 is covered by the outer box 10 and can be used to store products; the inner box 20 can be turned relative to the outer box 10 to a display state in a fully pulled-out state, so as to display the products located in the inner box 20. The first outer wall portion 12 of the outer box 10 is arranged away from the opening 21 of the inner box 20, and the first outer wall portion 12 is recessed inwardly into the opening 11 of the outer box 10, so as to form a clearance space on the inner side of the opening 11, which is used to provide clearance for the turning of the inner box 20. During the turning process of the inner box 20, the first inner wall portion 22 can gradually approach the first outer wall portion 12 and abut against the first outer wall portion 12 in the display state, and the first outer wall portion 12 supports the inner box 20 and restricts the inner box 20 from turning over further, so that the inner box 20 is stably maintained in the display state.

[0044] The inventors realize that in order to make way for the inner box 20, the side of the first outer wall portion 12 facing the opening 11 is spaced apart from the opening 11 to form a clearance space, and the clearance space will cause a step to be formed between the first outer wall portion 12 and the first inner wall portion 22 when the inner box 20 is closed. To this end, the embodiment of the present application further sets a layer plate 23 on the outer side of the first inner wall portion 22 away from the opening 21. When the inner box 20 is closed, the layer plate 23 is connected to the first outer wall portion 12 and is set flush. The layer plate 23 blocks the above-mentioned clearance space of the outer box, avoids the formation of an obvious step between the inner box 20 and the outer box 10, and is conducive to the inner box 20 and the outer box 10 forming a flush and complete whole, ensuring the exquisite appearance of the packaging box, and enhancing the sense of luxury and the user's experience.

[0045] In some embodiments, the layer adding plate 23 is provided with a recess 231 , and the recess 231 is recessed along the second direction Y in the outer surface of the layer adding plate 23 away from the first inner wall portion 22 .

[0046] Exemplarily, the recess 231 may be a groove, and in the second direction Y, the depth of the recess 231 is less than the thickness of the layer adding plate 23 .

[0047] As another example, the recess 231 may also be a through hole, and the recess 231 passes through the added layer board 23 along the second direction Y.

[0048] In the embodiment of the present application, a recess 231 is provided on the additional layer plate 23 , so as to provide an operating space for pulling out the inner box 20 , thereby facilitating the user to pull out the inner box 20 .

[0049] In some embodiments, reference Figure 1 , Figure 3 and Figure 7 The inner box 20 includes a second inner wall portion 24 and a third inner wall portion 25 which are arranged opposite to each other along the first direction X. In the closed state, the third inner wall portion 25 blocks at least a portion of the opening 11. The side of the additional layer 23 away from the first outer wall portion 12 along the first direction X is flush with the third inner wall portion 25.

[0050] The first inner wall portion 22 is connected to the second inner wall portion 24 and the third inner wall portion 25 at both ends along the first direction X. The third inner wall portion 25 may be an outer end wall of the inner box 20 , and the second inner wall portion 24 may be an inner end wall of the inner box 20 .

[0051] The added layer plate 23 includes a first side surface 232 away from the first outer wall portion 12 along the first direction X. The third inner wall portion 25 includes a first surface 251 away from the second inner wall portion 24 . The first side surface 232 and the first surface 251 are arranged flush.

[0052] In the embodiment of the present application, the layer plate 23 is arranged flush with the third inner wall portion 25 along the first direction X on the side away from the first outer wall portion 12. The layer plate 23 neither protrudes from the third inner wall portion 25 nor is recessed in the third inner wall portion 25, further improving the appearance and high-end feel of the packaging box structure 100.

[0053] In some embodiments, reference Figure 1 , Figure 5 and Figure 7 The inner box 20 includes a second inner wall portion 24 and a third inner wall portion 25 which are arranged opposite to each other along the first direction X. In the closed state, the third inner wall portion 25 blocks at least a portion of the opening 11. The outer surface of the second inner wall portion 24 which is away from the third inner wall portion 25 is an outwardly arched arc surface 241. The outer box 10 includes a second outer wall portion 13 which is arranged opposite to the first outer wall portion 12 along the second direction Y. In the display state, the arc surface 241 abuts against the second outer wall portion 13.

[0054] The second outer wall portion 13 includes an inner surface facing the first inner wall portion 22 , and the arc surface 241 can abut against the inner surface of the second outer wall portion 13 .

[0055] The inner surface of the second inner wall portion 24 facing the third inner wall portion 25 may be a flat surface or an outwardly concave arc surface.

[0056] The second inner wall portion 24 may be a partial structure formed by cutting a cylinder along a cutting plane parallel to the axial direction.

[0057] The second inner wall portion 24 may be a hollow structure with a hollow interior, or may be a solid structure.

[0058] The inner box 20 includes two fourth inner wall portions 26 arranged opposite to each other along the third direction Z. The first direction X, the second direction Y and the third direction Z intersect each other. Optionally, the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0059] The end surfaces of the two fourth inner wall portions 26 adjacent to the second inner wall portion 24 are also arc-shaped surfaces, and the arc shape of the arc-shaped surfaces is consistent with the arc shape of the arc-shaped surface 241 .

[0060] The second inner wall portion 24 is located at the pivot end of the inner box 20. During the flipping process of the inner box 20, the arc surface 241 can play a certain arc-shaped guiding role, thereby improving the smoothness of the flipping of the inner box 20. After the inner box 20 is flipped to the display state, the arc surface 241 is in full contact with the second outer wall portion 13, increasing the contact area between the inner box 20 and the outer box 10, thereby improving the stability of the inner box 20 in the display state.

[0061] In some embodiments, reference Figure 3 and Figure 4 The inner box 20 includes a second inner wall portion 24 and a third inner wall portion 25 which are arranged opposite to each other along the first direction X. In the closed state, the third inner wall portion 25 blocks a part of the opening 11. The third inner wall portion 25 is provided with an escape notch 252 which is recessed along the second direction Y from the edge of the third inner wall portion 25 close to the opening 21.

[0062] The avoidance gap 252 can be in an aesthetically pleasing shape such as a trapezoid, an inverted trapezoid, a square, or an arc.

[0063] In the second direction Y, the depth of the avoidance notch 252 may be less than or equal to the height of the third inner wall portion 25 .

[0064] The third inner wall portion 25 is located at the outer end of the inner box 20, that is, the pull-out end of the inner box 20. The avoidance notch 252 is set on the third inner wall portion 25, which not only facilitates the pulling out of the inner box 20, but also facilitates the taking and placing of products in the inner box 20, thereby improving the operational convenience.

[0065] In some embodiments, reference Figure 6 and Figure 7The inner box 20 and the outer box 10 are connected by a sliding mechanism, which includes a slide rail 31 and a slide member 32. The slide rail 31 extends along a first direction X, and the slide member 32 is slidably connected to the slide rail 31. The slide rail 31 is provided in one of the inner box 20 and the outer box 10, and the slide member 32 is provided in the other of the inner box 20 and the outer box 10.

[0066] The sliding member 32 may be inserted into the slide rail 31 and may slide along the first direction X on the slide rail 31 .

[0067] The number of the slide rail 31 and the number of the sliding members 32 may be one or more, and the plurality of sliding members 32 and the plurality of slide rails 31 are matched and connected one to one.

[0068] In the embodiment of the present application, the inner box 20 and the outer box 10 are connected by a sliding mechanism, which not only has a simple structure and assembly, but also has a reliable connection between the sliding member 32 and the slide rail 31 , and the sliding member 32 is not easy to separate from the slide rail 31 .

[0069] In some embodiments, reference Figure 6 and Figure 7 The inner box 20 includes a second inner wall portion 24 and a third inner wall portion 25 that are arranged opposite to each other along a first direction X, and two fourth inner wall portions 26 that are arranged opposite to each other along a third direction Z. In a closed state, the third inner wall portion 25 blocks at least a portion of the opening 11. The outer box 10 includes two third outer wall portions 14 that are arranged opposite to each other along a third direction Z. The first direction X, the second direction Y, and the third direction Z intersect each other. The slide rail 31 is arranged on the inner side of the third outer wall portion 14 facing the inner box 20, and the slide member 32 is arranged on the end of the fourth inner wall portion 26 adjacent to the second inner wall portion 24.

[0070] Optionally, the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0071] The two fourth inner wall portions 26 may be disposed parallel to each other. The two third outer wall portions 14 may be disposed parallel to each other.

[0072] The adjacent third outer wall portions 14 and fourth inner wall portions 26 may be arranged parallel to each other.

[0073] In the first direction X, the second outer wall 13 and the third outer wall 14 have the same size, and the first outer wall 12 is smaller than the second outer wall 13 and the third outer wall 14. The first outer wall 12 is recessed relative to the second outer wall 13 and the third outer wall 14 away from the opening 11.

[0074] At least a portion of the sliding member 32 may protrude outward from the fourth inner wall portion 26 so as to be slidably connected to the sliding rail 31 .

[0075] There are two slide rails 31 and two slide members 32. The two slide rails 31 are respectively arranged on the inner sides of the two third outer wall portions 14, and the two slide members 32 are respectively arranged on the fourth inner wall portion 26. The two slide members 32 are respectively matched with the two slide rails 31, thereby limiting the moving distance of the slide member 32 in the third direction Z, thereby reducing the possibility of the slide member 32 being separated from the slide rail 31.

[0076] The slide rail 31 is provided on the outer box 10, and the sliding member 32 is provided on the inner end of the inner box 20. When the inner box 20 is in any withdrawn state or displayed state, the slide rail 31 and the sliding member 32 can be hidden in the outer box 10 and will not be exposed, which further improves the appearance effect. More importantly, when the inner box 20 is in a fully withdrawn state, the sliding member 32 can be used as a pivot axis of the inner box 20, so that the inner box 20 is turned around the sliding member 32 to the display state. The structural design is simple and ingenious, and the inner box 20 is turned smoothly.
