Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] In the description of this utility model, it should be noted that the terms "first", "second", "third", etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] like Figures 1 to 7 As shown, this utility model discloses a foldable stackable box. The box body is formed by folding cardboard and includes: a base plate 1, side plates surrounding the base plate 1, and a cover plate opposite to the base plate 1. In this embodiment, the cardboard is corrugated cardboard.

[0033] The side panels are divided into: first side panel 2, second side panel 3, third side panel 4 and fourth side panel 5. The first side panel 2 and second side panel 3 are arranged opposite each other, and the third side panel 4 and fourth side panel 5 are arranged opposite each other.

[0034] The cover plate includes: a first cover plate 6 and a second cover plate 7. A first side plate 2 and a second side plate 3 are connected to the first cover plate 6 and the second cover plate 7 respectively. When the first side plate 2, the second side plate 3, the third side plate 4 and the fourth side plate 5 surround the circumference of the base plate 1, the first cover plate 6 and the second cover plate 7 are opened by folding.

[0035] The base plate 1 has a first stacking slot 13 and a second stacking slot 14 at the connection points with the first side plate 2 and the second side plate 3, respectively. The connection point between the first side plate 2 and the first cover plate 6 has a first stacking protrusion 23 corresponding to the first stacking slot 13, and the connection point between the second side plate 3 and the second cover plate 7 has a second stacking protrusion 33 corresponding to the second stacking slot 14. When two folding stacking boxes are stacked, the stacking protrusion of one folding stacking box is engaged with the stacking slot of the other folding stacking box to complete the stacking.

[0036] In this embodiment, the base plate 1 is provided with a first slot 11 and a second slot 12 at the connection points with the third side plate 4 and the fourth side plate 5, respectively. The ends of the third side plate 4 and the fourth side plate 5 are provided with a first insertion part 41 and a second insertion part 51 corresponding to the first slot 11 and the second slot 12, respectively. After the third side plate 4 and the fourth side plate 5 are folded along the first fold line 45 and the second fold line 55, respectively, the first insertion part 41 and the second insertion part 51 are inserted into the first slot 11 and the second slot 12 for fixation.

[0037] Secondly, the first side plate 2 is provided with a first support plate 21 and a second support plate 22, and the second side plate 3 is provided with a third support plate 31 and a fourth support plate 32. When the first side plate 2, the second side plate 3, the third side plate 4 and the fourth side plate 5 surround the bottom plate 1, the third side plate 4 and the fourth side plate 5 are folded along the first fold line 45 and the second fold line 55 respectively, and the first support plate 21, the second support plate 22, the third support plate 31 and the fourth support plate 32 are stacked on top of each other.

[0038] In some other embodiments, the first side panel 2 and the second side panel 3 are each provided with a support plate. When the side panels surround the circumference of the base plate, the third side panel 4 and the fourth side panel 5 are folded along the first fold line 45 and the second fold line 55, respectively, and the support plates are stacked on top of each other. In this case, although the production cost of this foldable stackable box can be reduced, the box body is prone to deformation and disintegration after folding, and is not stable enough. In some other embodiments, the first side panel 2 and the second side panel 3 are not provided with support plates and are connected by glue or the like. In this case, not only is the production cost of this foldable stackable box increased, but it is also prone to pollution. Furthermore, the glue or other adhesives will age after long-term use, causing the box body to deform and disintegrate.

[0039] Furthermore, the third side panel 4 and the fourth side panel 5 are respectively provided with a second slot 42 and a third slot 52 at their folding points. The first cover plate 6 and the second cover plate 7 are respectively provided with a third insertion part 61 and a fourth insertion part 71 corresponding to the second slot 42 and the third slot 52 on both sides of their ends. When the box is closed, the third insertion part 61 and the fourth insertion part 71 are inserted into the second slot 42 and the third slot 52 respectively for fixation.

[0040] In this embodiment, the second slot opening 42 and the third slot opening 52 are semi-circular, and the third insertion part 61 and the fourth insertion part 71 are fan-shaped to facilitate the opening and closing of the first cover plate 6 and the second cover plate 7. At the same time, the opening ends of the first cover plate 6 and the second cover plate 7 are wavy, which makes it easy to insert fingers to open the box when opening it, and also serves to improve the appearance.

[0041] In addition, the third side plate 4 is also provided with a first thickened side plate 43 and a second thickened side plate 44, and the fourth side plate 5 is also provided with a third thickened side plate 53 and a fourth thickened side plate 54. When the first side plate 2, the second side plate 3, the third side plate 4 and the fourth side plate 5 surround the circumference of the bottom plate 1, the first thickened side plate 43 and the third thickened side plate 53 are sequentially attached to the first side plate 2, and the second thickened side plate 44 and the fourth thickened side plate 54 are sequentially attached to the second side plate 3.

[0042] In this embodiment, the first thickened side plate 43 and the third thickened side plate 53 are respectively provided with a first groove 431 and a third groove 531 corresponding to the first stacking slot 13, and the second thickened side plate 44 and the fourth thickened side plate 54 are provided with a second groove 441 and a fourth groove 541 corresponding to the second stacking slot 14, so as to avoid blocking the stacking card protrusion from inserting into the stacking slot during stacking.

[0043] Furthermore, the first thickened side plate 43 and the third thickened side plate 53 are respectively provided with a first protrusion 432 and a third protrusion 532 corresponding to the first stacking protrusion 23, and the second thickened side plate 44 and the fourth thickened side plate 54 are provided with a second protrusion 442 and a fourth protrusion 542 corresponding to the second stacking protrusion 33, so as to support the stacking protrusion to be inserted into the stacking slot during stacking.

[0044] Meanwhile, the first side plate 2 and the second side plate 3 are respectively provided with a first carrying opening 24 and a second carrying opening 34, and the first thickened side plate 43 and the third thickened side plate 53 are provided with a third carrying opening 433 and a fifth carrying opening 533 corresponding to the first carrying opening 24, and the second thickened side plate 44 and the fourth thickened side plate 54 are provided with a fourth carrying opening 443 and a sixth carrying opening 543 corresponding to the second carrying opening 34, so as to avoid obstruction.

[0045] In some other embodiments, the third side plate 4 and the fourth side plate 5 are each provided with a thickened side plate. When the side plates surround the circumference of the base plate, the thickened side plates are respectively attached to the first side plate 2 and the second side plate 3. In some other embodiments, the third side plate 4 and the fourth side plate 5 are not provided with thickened side plates. In these cases, the stacking protrusions, due to having only one or two layers, have relatively poor stability and are prone to deformation during stacking, resulting in an unstable stacking state. Furthermore, if a carrying handle opening is provided, and only one thickened side plate is provided, or no thickened side plate is provided, the pressure exerted on the hand by the carrying handle opening is relatively large, which can easily cause injury. Additionally, the carrying handle opening is also more prone to deformation after use.

[0046] The above description is only a preferred embodiment of the present utility model. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
