[0006] A bottom box, comprising a bottom plate and a plurality of side plates, wherein the bottom plate is arranged at the bottom of the inner box, and the plurality of side plates are connected to the bottom plate and arranged around the inner box;

[0007] The top cover, when the top cover is placed on the outside of the bottom box, the multiple side panels are in contact with the outer peripheral surface of the inner box, so that the bottom box is in a folded state; when the top cover is removed from the bottom box, the multiple side panels are spread out under the action of gravity, so that the bottom box is in an open state.

[0008] The beneficial effects of the packaging box provided by the embodiment of the present application are as follows: when the top cover is sleeved on the outside of the bottom box, under the wrapping of the top cover, the multiple side panels are fitted with the outer peripheral surface of the inner box, so that the bottom box is in a folded state. At this time, the packaging box is not much different from an ordinary packaging box; when the top cover is removed from the bottom box, the multiple side panels automatically spread out like "flowers" under the action of gravity, so that the bottom box is in an open state. At this time, the packaging box is quite different from an ordinary packaging box, and the opening process is more beautiful, which increases the consumer's sense of surprise when opening the box and enhances the consumer experience.

[0009] In some embodiments, the inner box includes a box body and a drawer, the box body has a placement cavity opening toward the side panel when the bottom box is in a folded state, the drawer is in the placement cavity, and the drawer has a first storage cavity opening upward.

[0010] The beneficial effect of adopting the above technical solution is that the first storage cavity of the drawer can be used to store articles or accessories of articles. By placing the articles or accessories of articles in the first storage cavity of the drawer, they can be effectively protected.

[0011] In some embodiments, the box body further has a second storage cavity above the placement cavity, and the opening of the second storage cavity faces upward.

[0012] In some embodiments, the bottom box further includes a plurality of folding members, and the folding members are connected between two adjacent side panels.

[0013] The beneficial effects of adopting the above technical solution are as follows: by arranging a folding piece between two adjacent side panels, the aesthetics of the packaging box during opening is further improved, and at the same time, the two side panels are connected by the folding piece, which is conducive to the folding of multiple side panels.

[0014] In some embodiments, the folding member is a folding plate.

[0015] The beneficial effect of adopting the above technical solution is that after the folding plate is folded, there are only fold marks at the connection between the two sub-plates, which ensures the aesthetics of the folding plate.

[0016] In some embodiments, when the bottom box is in an open state, patterns are provided on the upper sides of the side panels and the folding panels.

[0017] The beneficial effect of adopting the above technical solution is that when the top cover is opened, consumers can not only see the item itself, but will also be attracted by the pattern during the opening process of the packaging box, making the overall structure more beautiful and creative, further enhancing the consumer experience.

[0018] In some embodiments, when the bottom box is in the open state, the bottom box is a flat plate.

[0019] The beneficial effect of adopting the above technical solution is that the drawer can be made larger while ensuring that the drawer can be pulled out.

[0020] In some embodiments, the bottom plate is fixedly connected to the inner box.

[0021] The beneficial effect of adopting the above technical solution is that by fixing the bottom plate and the inner box together, the inner box is prevented from moving relative to the bottom plate, which is conducive to the folding of the bottom box.

[0022] In some embodiments, when the top cover is sleeved on the outside of the bottom box, the side panel is entirely located inside the top cover.

[0023] The beneficial effect of adopting the above technical solution is: since a gap will be formed between two adjacent side panels after the bottom box is folded, by placing the side panels as a whole inside the top cover, consumers will not see the gap between the two adjacent side panels, which can improve the overall aesthetics of the packaging box.

[0024] In some embodiments, the projections of the inner box and the top cover are both rectangular, and four side panels are provided.

[0046] The embodiment of the first aspect of the present application provides a packaging box. Figure 1 The packaging box 10 includes an inner box 12 , a bottom box 11 and a top cover 13 .

[0047] The inner box 12 is used to store items, wherein the storage cavity of the inner box 12 is designed according to the shape and size of the items to be stored. It is understandable that one or more storage cavities of the inner box 12 can be provided.

[0048] Please also refer to Figure 2 and Figure 3 The bottom box 11 includes a bottom plate 111 and a plurality of side plates 112 . The bottom plate 111 is disposed at the bottom of the inner box 12 . The plurality of side plates 112 are connected to the bottom plate 111 and arranged around the inner box 12 .

[0049] The bottom plate 111 is provided at the bottom of the inner box 12. It is understood that the inner box 12 can be placed on the bottom plate 111 without being connected to the bottom plate 111, or the inner box 12 can be placed on the bottom plate 111 and fixedly connected to the bottom of the inner box 12. In this case, the bottom plate 111 and the inner box 12 can be made of the same material or different materials. Of course, the bottom plate 111 can also be integrally formed with the bottom of the inner box 12. In this case, the bottom plate 111 and the inner box 12 can be made of the same material.

[0050] The shape of the bottom plate 111 matches the projected shape of the inner box 12, and the size of the bottom plate 111 is slightly larger than the size of the inner box 12. It is understood that the shape of the bottom plate 111 can be polygonal, and the projected shape of the inner box 12 can be polygonal accordingly. For example, the shape of the bottom plate 111 and the projected shape of the inner box 12 can both be rectangular; or the shape of the bottom plate 111 can be circular, and the projected shape of the inner box 12 can be circular accordingly; or the shape of the bottom plate 111 can be elliptical, and the projected shape of the inner box 12 can be elliptical accordingly.

[0051] A plurality of side panels 112 are connected to the bottom panel 111 . It is understood that the side panels 112 can be integrally formed with the bottom panel 111 , or the side panels 112 can be connected to the bottom panel 111 by fasteners, snap-fitting, or the like.

[0052] Because the multiple side panels 112 are arranged around the inner box 12, when the multiple side panels 112 are in a folded state, the bottom panel 111 and the multiple side panels 112 form a cavity with an upward opening, and the inner box 12 is located in the cavity. It is understood that the top of the inner box 12 can be at the same height as the top of the cavity, or the top of the inner box 12 can be higher or lower than the top of the cavity.

[0053] It can be understood that when the shape of the bottom plate 111 is polygonal and the projection shape of the inner box 12 is polygonal, the side plate 112 can be a rectangular plate; when the shape of the bottom plate 111 is circular and the projection shape of the inner box 12 is circular, and when the shape of the bottom plate 111 is elliptical and the projection shape of the inner box 12 is elliptical, the side plate 112 can be an arc-shaped plate.

[0054] When the top cover 13 is placed on the outside of the bottom box 11, the multiple side panels 112 fit the outer circumference of the inner box 12, so that the bottom box 11 is in a folded state; when the top cover 13 is removed from the bottom box 11, the multiple side panels 112 spread out under the action of gravity, so that the bottom box 11 is in an open state.

[0055] Optionally, the shape of the top cover 13 is the same as that of the bottom box 11, and the size of the top cover 13 is slightly larger than that of the bottom box 11, so that the plurality of side panels 112 can be placed between the sides of the top cover 13 and the sides of the bottom box 11. The top cover 13 has a downward opening.

[0056] The multiple side panels 112 are fitted with the outer circumferential surface of the inner box 12. It can be understood that when the projected shape of the inner box 12 is a polygon, the multiple side panels 112 are respectively fitted with the multiple side surfaces of the inner box 12, that is, the multiple side surfaces of the inner box 12 form the outer circumferential surface of the inner box 12; when the projected shape of the inner box 12 is a circle or an ellipse, the multiple side panels 112 are respectively fitted with the multiple curved surfaces of the inner box 12, that is, the multiple curved surfaces form the outer circumferential surface of the inner box 12.

[0057] When the top cover 13 is removed from the bottom box 11 , the top cover 13 no longer limits the side panels 112 , so the multiple side panels 112 can be dispersed under the action of gravity.

[0058] The beneficial effects of the packaging box 10 provided by the embodiment of the present application are as follows: when the top cover 13 is sleeved on the outside of the bottom box 11, the multiple side panels 112 are in contact with the outer peripheral surface of the inner box 12 under the wrapping of the top cover 13, so that the bottom box 11 is in a folded state. At this time, the packaging box 10 is no different from an ordinary packaging box. Please also refer to Figures 1 to 3 When the top cover 13 is removed from the bottom box 11, the multiple side panels 112 automatically spread out like "flowers" under the action of gravity, so that the bottom box 11 is in an open state. At this time, the packaging box 10 is quite different from ordinary packaging boxes. The opening process is more beautiful, which increases the consumer's sense of surprise when opening the box and enhances the consumer experience.

[0059] Please also refer to Figures 3 to 5 In some embodiments, the inner box 12 includes a box body 121 and a drawer 122. The box body 121 has a placement cavity 1211 that opens toward the side panel 112 when the bottom box 11 is in a folded state. The drawer 122 is in the placement cavity 1211 and has a first storage cavity 1221 that opens upward.

[0060] The box body 121 has a placement cavity 1211 that opens toward the side panel 112 when the bottom box 11 is in the folded state. It can be understood that the opening of the placement cavity 1211 faces the horizontal direction, that is, the drawer 122 is placed in the placement cavity 1211 along the horizontal direction.

[0061] The placement cavity 1211 is adapted to the drawer 122 . For example, the placement cavity 1211 is a rectangular cavity, and correspondingly, the projected shape of the drawer 122 is a rectangle.

[0062] It is understood that one or more drawers 122 can be provided. When multiple drawers 122 are provided, the multiple drawers 122 can be arranged in the height direction of the box body 121. At this time, the multiple drawers 122 can share one placement cavity 1211, or multiple placement cavities 1211 can be provided in the height direction of the box body 121.

[0063] The first storage cavity 1221 of the drawer 122 can be used to store items or item accessories. Items or item accessories can be effectively protected by placing them in the first storage cavity 1221 of the drawer 122. The shape and size of the first storage cavity 1221 can be set according to the shape and size of the items to be stored.

[0064] In other embodiments, the opening of the placement cavity 1211 can be set upward, that is, the drawer 122 is placed into the placement cavity 1211 from top to bottom; or, the box body 121 does not have the placement cavity 1211, and no drawer 122 is set, that is, only the second storage cavity 1212 is provided on the box body 121.

[0065] Please also refer to Figure 3 and Figure 5 In some embodiments, the box body 121 further has a second storage cavity 1212 located above the placement cavity 1211 , and the opening of the second storage cavity 1212 faces upward.

[0066] Optionally, the second storage cavity 1212 is a rectangular cavity, wherein the depth of the second storage cavity 1212 can be set according to the size of the items to be stored.

[0067] It is understood that, depending on the number of items to be stored, one or more second storage cavities 1212 may be provided. When multiple second storage cavities 1212 are provided, the multiple second storage cavities 1212 may be arranged in a matrix on the box body 121. Of course, the multiple second storage cavities 1212 may also be arranged in a random order on the box body 121.

[0068] In other embodiments, the second storage cavity 1212 may not be provided, and only the drawer 122 is provided in the placement cavity 1211 .

[0069] Please also refer to Figure 2 and Figure 3 In some embodiments, the bottom box 11 further includes a plurality of folding members 113 , and the folding members 113 are connected between two adjacent side panels 112 .

[0070] Optionally, a folding piece 113 is connected between any two adjacent side panels 112 .

[0071] When the bottom box 11 is opened, the multiple side panels 112 spread out under the action of gravity, and the folding piece 113 unfolds under the tension of two adjacent side panels 112; when the bottom box 11 is folded, the multiple side panels 112 move closer to the inner box 12, and the folding piece 113 folds up and is located between the side panels 112 and the bottom box 11.

[0072] By providing a folding piece 113 between two adjacent side panels 112 , the aesthetics of the packaging box 10 during the opening process is further improved. At the same time, the two side panels 112 are connected by the folding piece 113 , which is conducive to the folding of multiple side panels 112 .

[0073] In other embodiments, the folding piece 113 may not be provided between two adjacent side panels 112 .

[0074] Please refer to Figure 2 and Figure 3 In some embodiments, the folding member 113 is a folding plate.

[0075] Optionally, the folding plate includes two identical sub-plates, and the connection between the two sub-plates is a folding mark 1131, which can be used to quickly fold the folding plate. It is understood that the two sub-plates can both be triangular plates, that is, the folding plate is a triangular plate; the two sub-plates can both be trapezoidal plates, that is, the folding plate is a trapezoidal plate.

[0076] By adopting the above technical solution, after the folding plate is folded, there is only a folding mark 1131 at the connection between the two sub-plates, thereby ensuring the aesthetics of the folding plate.

[0077] In other embodiments, the folding member 113 may be a flexible member, that is, the folding member 113 may be folded arbitrarily. For example, the folding member 113 may include a plurality of folding ropes, or the folding member 113 may also be a folding cloth.

[0078] In some embodiments, when the bottom box 11 is in the open state, patterns are provided on the upper sides of the side panels 112 and the folding panels.

[0079] It can be understood that when the bottom box 11 is in the folded state, consumers cannot see the patterns on the side panels 112 and the folding panels, which can add a sense of mystery.

[0080] Among them, different patterns can be set on the side panels 112 and the folding panels according to different products to satisfy consumers' sense of freshness.

[0081] When the top cover 13 is opened, consumers can not only see the items themselves, but will also be attracted by the patterns during the opening process of the packaging box 10, making the overall structure more beautiful and creative, further enhancing the consumer experience.

[0082] Please also refer to Figure 3 and Figure 6 In some embodiments, when the bottom box 11 is in the open state, the bottom box 11 is a flat plate.

[0083] It can be understood that after the packaging box 10 is placed on the table and opened, the bottom plate 111, side panels 112 and folding piece 113 of the bottom box 11 are all in contact with the table, that is, the bottom plate 111, side panels 112 and folding piece 113 are on the same plane.

[0084] By adopting the above technical solution, the drawer 122 can be made larger while ensuring that the drawer 122 can be pulled out.

[0085] In other embodiments, when the bottom box 11 is in the open state, the bottom box 11 has a conical structure, that is, the angle between the side panel 112 and the bottom panel 111 is 0-90°. For example, the angle between the two can be 30°, 45°, 60°, etc.

[0086] In some embodiments, the bottom plate 111 is fixedly connected to the inner box 12 .

[0087] Optionally, the bottom plate 111 and the inner box 12 are both made of paper material, and the bottom plate 111 and the inner box 12 are connected together by bonding.

[0088] By fixing the bottom plate 111 and the inner box 12 together, the inner box 12 is prevented from moving relative to the bottom plate 111 , which facilitates the folding of the bottom box 11 .

[0089] In other embodiments, the bottom plate 111 and the inner box 12 may also be fixed together by fastener connection, snap connection, etc.

[0090] Please refer to Figure 1 In some embodiments, when the top cover 13 is sleeved on the outside of the bottom box 11 , the side panel 112 is entirely located inside the top cover 13 .

[0091] It can be understood that when the top cover 13 is sleeved on the outside of the bottom box 11 , except for the bottom plate 111 , the rest of the bottom box 11 is covered by the top cover 13 , that is, when the packaging box 10 is placed on a table, only the top cover 13 can be seen.

[0092] After the bottom box 11 is folded, a gap is formed between two adjacent side panels 112 . By placing the side panels 112 entirely within the top cover 13 , consumers will not see the gap between the two adjacent side panels 112 , thereby improving the overall aesthetics of the packaging box 10 .

[0093] In other embodiments, the top cover 13 may cover a portion of the side panel 112 , for example, the top cover 13 may cover one half, one third, etc. of the side panel 112 , as long as the bottom box 11 is not opened while the inner box 12 is sealed.

[0094] Please also refer to Figure 2 and Figure 3 In some embodiments, the projections of the inner box 12 and the top cover 13 are both rectangular, and four side panels 112 are provided.

[0095] Optionally, the projections of the inner box 12 and the top cover 13 are both square.

[0096] The folding piece 113 between two adjacent side panels 112 is in the shape of a triangle, that is, the bottom box 11 is in the shape of an octagon as a whole after being unfolded.
