Technical Field
[0001] This utility model relates to the field of folding packaging box technology, specifically a folding packaging box with built-in partitions. Background Technology
[0002] Folding packaging boxes offer advantages such as low processing costs, convenient storage and transportation, applicability to various printing methods, suitability for automated packaging, ease of sales and display, good recyclability, and environmental friendliness. Currently, with increasing environmental awareness, folding packaging boxes are widely used in the packaging of products such as juice, milk, cooked food, snacks, pharmaceuticals, and cosmetics. Furthermore, the ability to stack, transport, and store folding packaging boxes flat before folding significantly reduces storage and transportation costs. Therefore, the demand for folding packaging boxes will continue to increase in the future, placing higher demands on their production quality. Designing and producing boxes that can be opened without cutting or damaging the box with tools and that do not require glue or other consumables for fixing are crucial for recycling and environmental protection. Utility Model Content
[0003] The purpose of this utility model is to provide a folding packaging box with built-in dividers. While facilitating unpacking and unfolding, the built-in dividers partition the box, allowing for separate storage, recycling, and reuse. To achieve the above objective, this utility model adopts the following technical solution:
[0004] This utility model discloses a folding packaging box with built-in partitions. The box body is formed by folding cardboard and includes: a bottom plate, side plates surrounding the bottom plate, and a cover plate opposite to the bottom plate.
[0005] The side panels are divided into: a first side panel, a second side panel, a third side panel, and a fourth side panel. The first side panel and the second side panel are arranged opposite each other, and the third side panel and the fourth side panel are arranged opposite each other. Both the first side panel and the second side panel are provided with an inner partition and a side partition. After the inner partition and the side partition are folded, the box body is divided into several placement areas.
[0006] The cover plate includes a first cover plate and a second cover plate. The third side plate and the fourth side plate are respectively connected to the first cover plate and the second cover plate. When the side plates surround the circumference of the base plate, the first cover plate and the second cover plate are opened by folding.
[0007] The first side plate and the second side plate are connected to the bottom plate on one side, and at least one side of the first side plate and the second side plate connected to the bottom plate is connected to the inner partition. The side partition is formed by folding the first side plate and the second side plate with the inner partition.
[0008] Furthermore, the first side plate is connected to the first inner partition and the second inner partition on the adjacent sides connected to the bottom plate, respectively. The first inner partition and the first side plate are folded along the first fold line and the second fold line to form the first side partition. The second inner partition and the first side partition are folded along the third fold line and the fourth fold line to form the second side partition. The first inner partition and the second inner partition overlap to form a double-layer support structure.
[0009] The second side plate is connected to the third inner partition and the fourth inner partition on the adjacent sides connected to the bottom plate, respectively. The third inner partition and the second side plate are folded along the fifth fold line and the sixth fold line to form the third side partition. The fourth inner partition and the second side partition are folded along the seventh fold line and the eighth fold line to form the fourth side partition. The third inner partition and the fourth inner partition overlap to form a double-layer support structure.
[0010] Furthermore, the first cover plate and the second cover plate are provided with insertion parts on the opposite side, and the insertion parts and / or the inner partition are provided with slots for insertion and fixation when the box is closed.
[0011] Furthermore, the length of the plug-in part is the same as the length of the inner partition, and both the plug-in part and the inner partition are provided with slots. The length of the slot is half the length of the plug-in part or the inner partition. When the box is closed, after the plug-in part is inserted into the inner partition, the plug-in part further divides the placement area inside the box.
[0012] Furthermore, the first side plate and the second side plate are provided with an upper partition on the opposite side connected to the bottom plate. After the inner partition and the side partition are folded to form a corresponding placement area, the upper partition covers the top of the placement area.
[0013] The upper partition is also provided with a corresponding slot, which facilitates the insertion and fixing of the plug-in part and the inner partition when the box is closed.
[0014] Preferably, the two sides of the end of the insertion part are inclined inward to form a chamfer to facilitate insertion.
[0015] After adopting the above technical solution, the present invention has the following effects:
[0016] 1. This utility model is equipped with several internal partitions, which can divide the box into sections to meet the need to separate the objects stored in the box, store various types of items, and improve efficiency.
[0017] 2. This utility model does not require cutting or damaging the box with knives when unpacking. It can be opened by using the first and second cover plates. It is fixed by the insertion of the inner partition or the plug part, without the need for consumables such as glue. This makes it easy to unfold this split folding cardboard box for further recycling and reuse.
[0018] 3. This utility model has a simple structure. Folding the cardboard can reduce production costs and minimize damage to the box during unpacking and unfolding, thus meeting environmental protection requirements. Attached Figure Description

Detailed Implementation
[0035] 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.
[0036] 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.
[0037] Example 1
[0038] like Figures 1 to 5 As shown, this utility model discloses a folding packaging box with built-in partitions. The box body is formed by folding cardboard and includes: a bottom plate 1, side plates surrounding the bottom plate 1, and a cover plate opposite to the bottom plate 1.
[0039] The side panels are divided into: first side panel 2, second side panel 3, third side panel 4 and fourth side panel 5. First side panel 2 and second side panel 3 are arranged opposite each other, and third side panel 4 and fourth side panel 5 are arranged opposite each other. Both first side panel 2 and second side panel 3 are provided with inner partitions and side partitions. After the inner partitions and side partitions are folded, the box is divided into several placement areas.
[0040] The cover plate includes: a first cover plate 6 and a second cover plate 7. A third side plate 4 and a fourth side plate 5 are respectively connected to the first cover plate 6 and the second cover plate 7. 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.
[0041] In this embodiment, one side of the first side plate 2 and the second side plate 3 is connected to the bottom plate 1, and the first side plate 2 and the second side plate 3 are both connected to the inner partition on the adjacent sides connected to the bottom plate 1, and the first side plate 2 and the second side plate 3 are folded together with the inner partition to form a side partition.
[0042] The first side plate 2 is connected to the first inner partition 21 and the second inner partition 22 on the adjacent sides connected to the bottom plate 1, respectively. The first inner partition 21 and the first side plate 2 are folded along the first fold line 231 and the second fold line 232 to form the first side partition 23. The second inner partition 22 and the first side partition 2 are folded along the third fold line 241 and the fourth fold line 242 to form the second side partition 24. The first inner partition 21 and the second inner partition 22 overlap to form a double-layer support structure.
[0043] The second side plate 3 is connected to the third inner partition 31 and the fourth inner partition 32 on the adjacent sides connected to the bottom plate 1, respectively. The third inner partition 31 and the second side plate 3 are folded along the fifth fold line 331 and the sixth fold line 332 to form the third side partition 33. The fourth inner partition 32 and the second side plate 3 are folded along the seventh fold line 341 and the eighth fold line 342 to form the fourth side partition 34. The third inner partition 31 and the fourth inner partition 32 overlap to form a double-layer support structure.
[0044] In some other embodiments, only one side of the first side plate 2 and the second side plate 3 connected to the bottom plate 1 is connected to the inner partition. After folding, the inner partition is a single-layer structure. In this case, the cost of the folding packaging box with the built-in partition is reduced, but the support is relatively weak.
[0045] Secondly, the first inner partition 21, the second inner partition 22, the third inner partition 31, and the fourth inner partition 32 are respectively provided with a first slot 211, a second slot 221, a fourth slot 311, and a fifth slot 321. Simultaneously, the first cover plate 6 and the second cover plate 7 are respectively provided with a first insertion part 61 and a second insertion part 71 on their opening sides, and the first insertion part 61 and the second insertion part 71 are respectively provided with a corresponding seventh slot 611 and an eighth slot 711. When the box is closed, the inner partitions and the insertion parts are fixed together by the insertion of the slots.
[0046] In this embodiment, the lengths of the first insertion portion 61 and the second insertion portion 71 are the same as the lengths of the first inner partition 21, the second inner partition 22, the third inner partition 31, and the fourth inner partition 32, and the lengths of the seventh slot 611 and the eighth slot 711 are half the lengths of the first insertion portion 61 and the second insertion portion 71. Furthermore, the lengths of the first slot 211, the second slot 221, the fourth slot 311, and the fifth slot 321 are also half the lengths of the first inner partition 21, the second inner partition 22, the third inner partition 31, and the fourth inner partition 32.
[0047] When the box is closed, the first insertion part 61 and the second insertion part 71 are inserted into the first inner partition 21, the second inner partition 22, the third inner partition 31 and the fourth inner partition 32. The first insertion part 61 and the second insertion part 71 further divide the placement area inside the box to form six placement areas for placing a large number of small items.
[0048] In addition, the first side plate 2 and the second side plate 3 are respectively provided with a first upper partition 25 and a second upper partition 35 on the opposite side connected to the bottom plate 1. After the first inner partition 21, the second inner partition 22, the third inner partition 31 and the fourth inner partition 32, as well as the first side partition 23, the second side partition 24, the third side partition 33 and the fourth side partition 34 are folded to form the corresponding placement areas, the first upper partition 25 and the second upper partition 35 respectively cover the top of the corresponding placement area.
[0049] The first upper partition 25 and the second upper partition 35 are respectively provided with the third slot 251 and the sixth slot 351, which facilitate the insertion and fixing of the first insertion part 61 and the second insertion part 71 with the first inner partition 21, the second inner partition 22, the third inner partition 31 and the fourth inner partition 32 when the box is closed.
[0050] In this embodiment, the two sides of the ends of the first insertion part 61 and the second insertion part 71 are inclined inward to form a chamfer, so as to facilitate insertion.
[0051] Example 2
[0052] The difference between this embodiment and Embodiment 1 is that the positions of the slot openings on the inner partition and the plug-in part are different.
[0053] like Figures 6 to 9 as well as Figure 14As shown, in this embodiment, the first inner partition 21, the second inner partition 22, the third inner partition 31, and the fourth inner partition 32 are respectively provided with a first slot 211, a second slot 221, a fourth slot 311, and a fifth slot 321. The first cover plate 6 and the second cover plate 7 are respectively provided with a first insertion part 61 and a second insertion part 71 on their respective opening sides, but the first insertion part 61 and the second insertion part 71 are not provided with corresponding slots, and the lengths of the first insertion part 61 and the second insertion part 71 are much smaller than the lengths of the first inner partition 21, the second inner partition 22, the third inner partition 31, and the fourth inner partition 32.
[0054] In this case, when the box is closed, after the first insertion part 61 and the second insertion part 71 are inserted and fixed with the first inner partition 21, the second inner partition 22, the third inner partition 31 and the fourth inner partition 32, the first insertion part 61 and the second insertion part 71 will no longer separate the placement areas inside the box, but will maintain the original three placement areas for placing a small number of large items.
[0055] Example 3
[0056] The difference between this embodiment and Embodiments 1 and 2 is that the positions of the slot openings on the inner partition and the plug-in part are different.
[0057] like Figures 10 to 14 As shown, in this embodiment, the first cover plate 6 and the second cover plate 7 are respectively provided with a first insertion part 61 and a second insertion part 71 on their respective opening sides. The first insertion part 61 and the second insertion part 71 are respectively provided with a corresponding seventh slot 611 and an eighth slot 711. However, the first inner partition 21, the second inner partition 22, the third inner partition 31 and the fourth inner partition 32 are not provided with corresponding slots, and the lengths of the first insertion part 61 and the second insertion part 71 are much smaller than the lengths of the first inner partition 21, the second inner partition 22, the third inner partition 31 and the fourth inner partition 32.
[0058] In this case, when the box is closed, after the first insertion part 61, the second insertion part 71 are inserted and fixed with the first inner partition 21, the second inner partition 22, the third inner partition 31 and the fourth inner partition 32, the first insertion part 61 and the second insertion part 71 will no longer separate the placement areas inside the box. Instead, they will maintain the original three placement areas as in Embodiment 2, which are used to place a small number of large items.
[0059] 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.
