Technical Field

[0001] This invention relates to a modular packaging box. Background Technology

[0002] Packaging boxes, as the name suggests, are boxes used to package products. They can be classified by material, such as cardboard boxes, tin boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, corrugated boxes, PVC boxes, etc., or by product name, such as mooncake boxes, tea boxes, goji berry boxes, candy boxes, exquisite gift boxes, local specialty product boxes, wine boxes, chocolate boxes, food, medicine, and health product boxes, food packaging boxes, tea packaging boxes, stationery boxes, etc. The functions of packaging boxes include ensuring product safety during transportation and enhancing the product's perceived quality. The main material for tin boxes and cans is tinplate.

[0003] The problem with existing packaging boxes is that their simple structure and single packaging cavity make them unable to meet complex warranty requirements.

[0004] Therefore, how to increase the complexity of the guarantee has become a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution: a shell and primary packaging boxes. The shell includes a bottom plate and a top plate located above the bottom plate. There are four primary packaging boxes, each located between the bottom plate and the top plate. Each primary packaging box is a cuboid of equal height, with its height vertically aligned. Each primary packaging box has a first mating surface and a second mating surface that are perpendicular to each other. Both the first and second mating surfaces are parallel to the vertical. The first mating surface of one primary packaging box is fitted to the second mating surface of another packaging box, and each first mating surface is uniquely fitted to one of the second mating surfaces. The top plate is rotatably mounted on the bottom plate, and the rotation axis of the top plate relative to the bottom plate is vertically arranged. Each of the primary packaging boxes is provided with a third mating surface parallel to the first mating surface and a fourth mating surface parallel to the second mating surface. The top plate is provided with an anti-detachment component corresponding to each primary packaging box. The top plate has a closed position and an open position. When the top plate is in the closed position, the vertical projection of each third mating surface overlaps with the corresponding anti-detachment component, and the vertical projection of each fourth mating surface overlaps with the corresponding anti-detachment component.

[0009] The present invention is further configured such that: the third mating surface on each of the primary packaging boxes is coplanar with the fourth mating surface on the adjacent primary packaging box; both the top plate and the bottom plate are square; the third mating surface of each of the primary packaging boxes is parallel to or coincides with one side of the bottom plate; and when the top plate is in the closed position, the third mating surface of each of the primary packaging boxes is parallel to or coincides with one side of the top plate.

[0010] The present invention is further configured such that the sum of the horizontal side length of each of the third mating surfaces and the horizontal side length of the coplanar fourth mating surfaces is equal to the side length of the third mating surface corresponding to the bottom plate, and the sum of the horizontal side length of each of the third mating surfaces and the horizontal side length of the coplanar fourth mating surfaces is equal to the side length of the third mating surface corresponding to the top plate.

[0011] The present invention is further configured such that the horizontal distance between the first anti-detachment plate corresponding to the third mating surface coplanar with the anti-detachment baffle and the corresponding fourth mating surface is greater than or equal to the horizontal side length of the corresponding fourth mating surface.

[0012] The present invention is further configured such that: each of the primary packaging boxes is provided with a box cavity, each of the third mating surfaces is provided with a cavity opening, each of the box cavities is provided with a secondary packaging box, each of the secondary packaging boxes is provided with a retrieval cavity and a storage cavity that are sequentially moved away from the corresponding cavity opening, and each of the secondary packaging boxes is provided with a cavity partition plate for separating the retrieval cavity and the storage cavity. When the top plate is in the closed position, each anti-detachment component is located on the movement trajectory of the corresponding cavity partition plate along the movement trajectory of the secondary packaging box detaching from the box cavity.

[0013] The present invention is further configured such that the upper ends of each of the retrieval chambers and storage chambers are open.

[0014] The invention is further configured as follows: a storage cavity is provided inside the positioning column, a mounting sleeve is provided inside the storage cavity, a rotating insert is provided on the top plate and inserted into the mounting sleeve, a plurality of fun beads are provided inside the storage cavity, a primary extraction hole adapted to the shape and size of the fun beads is provided through the bottom plate, a control cavity communicating with the primary extraction hole is provided below the primary extraction hole on the bottom plate, a control component that rotates synchronously with the top plate is provided inside the control cavity, a control groove for the fun beads to enter is provided vertically through the control component, a secondary extraction hole communicating with the control cavity is provided through the bottom plate below the storage cavity, when the top plate is in the closed position, the control groove is located on the extension trajectory of the primary extraction hole, when the top plate is in the open position, the control groove is located on the extension trajectory of the secondary extraction hole, and an insertion hole communicating with the storage cavity is provided through the top plate.

[0016] By adopting the above technical solution, 1. Four primary packaging boxes are installed on the shell simultaneously, allowing different items to be packaged in different primary packaging boxes, increasing the diversity and complexity of packaging; 2. The four primary packaging boxes need to be inserted between the top and bottom plates when the top plate is in the open position. After each primary packaging box is installed, the top plate is rotated to the closed position. At this time, the upper and lower sides of each primary packaging box are limited by the top and bottom plates, while the first mating surface, second mating surface, third mating surface, and fourth mating surface are all limited in their respective directions and cannot move, thus ensuring the installation stability of each primary packaging box on the shell. Moreover, there is a mutual limiting relationship between each primary packaging box. Therefore, the shell and the four primary packaging boxes need to be treated as a whole to achieve stable packaging. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] like Figures 1-4 As shown, this invention discloses a modular packaging box, including a shell and primary packaging boxes 2. The shell includes a bottom plate 11 and a top plate 12 located above the bottom plate 11. There are four primary packaging boxes 2, each located between the bottom plate 11 and the top plate 12. Each primary packaging box 2 is a cuboid of equal height, with its height vertically aligned. Each primary packaging box 2 has a first mating surface 21 and a second mating surface 22 that are perpendicular to each other, and both the first mating surface 21 and the second mating surface 22 are parallel to the vertical. The first mating surface 21 of each primary packaging box 2 is fitted to the second mating surface 22 of another packaging box, with each first mating surface 21 uniquely mating to one of the second mating surfaces 22. The top plate 12 is rotatably mounted on the bottom plate. 11, and the rotation axis of the top plate 12 relative to the bottom plate 11 is arranged vertically. Each of the first-level packaging boxes 2 is provided with a third mating surface 23 parallel to the first mating surface 21 and a fourth mating surface 24 parallel to the second mating surface 22. The top plate 12 is provided with an anti-detachment component 121 corresponding to each first-level packaging box 2. The top plate 12 has a closed position 41 and an open position 42. When the top plate 12 is in the closed position 41, the projection of each third mating surface 23 in the vertical direction overlaps with the corresponding anti-detachment component 121, and the projection of each fourth mating surface 24 in the vertical direction overlaps with the corresponding anti-detachment component 121. When the top plate 12 is in the open position 42, the projection of each third mating surface 23 in the vertical direction is misaligned with the anti-detachment component 121 or the projection of each fourth mating surface 24 in the vertical direction is misaligned with the anti-detachment component 121.

[0036] in, Figures 1-4 The images shown are four identical primary packaging boxes 2 under specific conditions. However, under maximum protection, the shape of the primary packaging boxes 2 can vary, and... Figure 5 Arranged in the manner shown, among which, Figures 1-4 The top plate 12 and bottom plate 11 shown are regular squares. However, under maximum protection, the top plate 12 and bottom plate 11 can be of any shape, as long as they satisfy the condition that when the top plate 12 is in the closed position, the upper side of each primary packaging box 2 is fully or partially covered by the top plate 12, and the lower side of each primary packaging box 2 is fully or partially covered by the bottom plate 11. Figures 1-4The exhibit shows that the anti-detachment component 121 is L-shaped and integrally molded onto the top plate 12. Under the maximum protection range, the anti-detachment component 121 can be installed on the top plate 12 in any fixing method, and the shape of the anti-detachment component 121 can be arbitrary. It is only necessary that when the top plate 12 is in the closed position 41, the projection of each third mating surface 23 along the vertical direction overlaps with the corresponding anti-detachment component 121, and the projection of each fourth mating surface 24 along the vertical direction overlaps with the corresponding anti-detachment component 121. When the top plate 12 is in the open position 42, the projection of each third mating surface 23 along the vertical direction is misaligned with the anti-detachment component 121, or the projection of each fourth mating surface 24 along the vertical direction is misaligned with the anti-detachment component 121.

[0037] Therefore, 1. Four primary packaging boxes 2 are installed on the shell at the same time, so that different items can be packaged in different primary packaging boxes 2, which increases the diversity and complexity of packaging; 2. The four primary packaging boxes 2 need to be installed between the top plate 12 and the bottom plate 11 when the top plate 12 is in the open position 42, and after each primary packaging box 2 is installed in place, the top plate 12 is rotated to the closed position 41. At this time, the upper and lower sides of each primary packaging box 2 are limited by the top plate 12 and the bottom plate 11, and the first mating surface 21, the second mating surface 22, the third mating surface 23 and the fourth mating surface 24 are all limited in their respective directions and cannot move, thereby ensuring the installation stability of each primary packaging box 2 installed on the shell. Moreover, there is a mutual limiting relationship between each primary packaging box 2. Therefore, the shell and the four primary packaging boxes 2 need to be treated as a whole to achieve stable packaging.

[0038] Preferably, each of the anti-detachment components 121 in this embodiment includes a first anti-detachment plate 1211 and a second anti-detachment plate 1212. When the top plate 12 is in the closed position 41, each first anti-detachment plate 1211 is parallel to the corresponding third mating surface 23, each second anti-detachment plate 1212 is parallel to the corresponding fourth mating surface 24, each third mating surface 23 is located on the movement trajectory of the corresponding first anti-detachment plate 1211, and each fourth mating surface 24 is located on the movement trajectory of the corresponding second anti-detachment plate 1212.

[0039] Therefore, when the top plate 12 is in the closed position 41, 1. the anti-detachment component 121 uses a first anti-detachment plate 1211 to limit the sliding of the primary packaging box 2 along the third mating surface 23, and a second anti-detachment plate 1212 to limit the sliding of the primary packaging box 2 along the fourth mating surface 24. Under the parallel directional cooperation, the movement of the primary packaging box 2 along the third mating surface 23 or the fourth mating surface 24 will abut against the parallel first anti-detachment plate 1211 or the second anti-detachment plate 1212, making it less likely to generate concentrated stress on the primary packaging box 2 and cause damage; 2. the first anti-detachment plate 1211 is subjected to the rotation of the third mating surface 23. The second anti-detachment plate 1212 is limited by the rotation of the fourth mating surface 24, thereby ensuring that the top plate 12 is stably in the closed position 41 and preventing accidental opening. It should be noted that the rotation of the top plate 12 requires either the first anti-detachment plate 1211 or the second anti-detachment plate 1212 to forcibly pass over the third mating surface 23 or the fourth mating surface 24 (determined by the direction of rotation). In this embodiment, the second anti-detachment plate 1212 is used to forcibly pass over the fourth mating surface 24 to achieve opening, while closing requires the second anti-detachment plate 1212 to forcibly pass over the third mating surface 23. The above effect can be achieved by referring to the L-shaped locking block and other structures in existing structures.

[0040] Preferably, in this embodiment, the first anti-detachment plate 1211 and the second anti-detachment plate 1212 are integrally formed together, and both the first anti-detachment plate 1211 and the second anti-detachment plate 1212 are integrally formed with the top plate 12, which makes the structure stronger and simplifies the processing technology.

[0041] Furthermore, in this embodiment, the base plate 11 is provided with anti-detachment baffles 111 corresponding to each primary packaging box 2. Each anti-detachment baffle 111 abuts against the corresponding fourth mating surface 24. The base plate 11 is provided with a four-sided prism-shaped positioning post 112 protruding upward. Each second mating surface 22 is in contact with one side of the positioning post 112. Therefore, each anti-detachment baffle 111 and positioning post 112 effectively limits the primary packaging box 2 along the direction of the fourth mating surface 24, so that when the top plate 12 is in the open position 42, the primary packaging box 2 is detached from the direction of the third mating surface 23, thereby determining the disassembly and assembly direction.

[0042] Preferably, in this embodiment, each anti-detachment baffle 111 and positioning post 112 is integrally formed on the base plate 11, making the processing and assembly of the base plate 11 more convenient.

[0043] Preferably, in this embodiment, the third mating surface 23 on each of the primary packaging boxes 2 is coplanar with the fourth mating surface 24 on the adjacent primary packaging box 2. Both the top plate 12 and the bottom plate 11 are square. The third mating surface 23 of each primary packaging box 2 is parallel to or coincides with one side of the bottom plate 11. When the top plate 12 is in the closed position 41, the third mating surface 23 of each primary packaging box 2 is parallel to or coincides with one side of the top plate 12. Therefore, when the four primary packaging boxes 2 are installed into the shell, they combine to form a complete cuboid, making the outer perimeter structure more... In addition, the top plate 12 and the bottom plate 11 are square, which can effectively adapt to the cuboid shape of the four-piece primary packaging box 2, making the whole more orderly. Preferably, the sum of the horizontal side length of each of the third mating surfaces 23 and the horizontal side length of the coplanar fourth mating surfaces 24 is equal to the side length of the corresponding third mating surface 23 of the bottom plate 11, and the sum of the horizontal side length of each of the third mating surfaces 23 and the horizontal side length of the coplanar fourth mating surfaces 24 is equal to the side length of the corresponding third mating surface 23 of the top plate 12. This achieves that the top plate 12 and the bottom plate 11 are perfectly adapted to the four-piece primary packaging box 2, minimizing the volume and achieving the best state.

[0044] Preferably, in this embodiment, the horizontal distance d1 between the first anti-detachment plate 1211 corresponding to the third mating surface 23 coplanar with the anti-detachment baffle 111 and the corresponding fourth mating surface 24 is greater than or equal to the horizontal side length of the corresponding fourth mating surface 24. In this embodiment, the distance d1 is equal, so that while ensuring the maximum length of the anti-detachment baffle 111, it can also be achieved that when at least one primary packaging box 2 is missing, it can be disassembled by moving the primary packaging box 2 without rotating the top plate 12 to the open position 42. Therefore, only when four primary packaging boxes 2 are assembled at the same time can a complete and stable packaging box be formed.

[0045] Combination Figure 6 As shown, each of the primary packaging boxes 2 in this embodiment is provided with a box cavity, and each of the third mating surfaces 23 is provided with a cavity opening. Each of the box cavities is provided with a secondary packaging box 3. Each of the secondary packaging boxes 3 is provided with a retrieval cavity 31 and a storage cavity 32 that are sequentially moved away from the corresponding cavity openings. Each of the secondary packaging boxes 3 is provided with a cavity partition plate 33 for separating the retrieval cavity 31 and the storage cavity 32. When the top plate 12 is in the closed position 41, each anti-detachment component 121 is located on the movement trajectory of the corresponding cavity partition plate 33 along the secondary packaging box 3 detaching from the box cavity. Therefore, pull-out packaging is achieved by inserting the secondary packaging box 3 into the primary packaging box 2. The items to be packaged can be placed into the retrieval cavity 31 and the storage cavity 32 for packaging. When the top plate 12 is in the closed position 41, the secondary packaging box 3 can be pulled out so that part of the retrieval cavity 31 is pulled out of the cavity opening for retrieval, making the packaging effect more diverse.

[0046] Preferably, in this embodiment, the upper ends of each of the retrieval chambers 31 and storage chambers 32 are open to enable retrieval and placement of items from the upper end.

[0047] Combination Figures 7-9 As shown, in this embodiment, the positioning post 112 is provided with a rectangular storage cavity 1121. In addition, the lower end of the top plate 12 is provided with four rotation limiting protrusions 122 that extend into the storage cavity 1121. Each rotation limiting protrusion 122 is provided with a first positioning surface 1221 and a second positioning surface 1222. When the top plate 12 is in the closed position 41, each of the first positioning surfaces 1221 is in contact with the four horizontal sides of the storage cavity 1121. When the top plate 12 is in the open position 42, each of the second positioning surfaces 1222 is in contact with the four horizontal sides of the storage cavity 1121.

[0048] Combination Figures 10-16 As shown, in this embodiment, the storage cavity 1121 is provided with a mounting sleeve 113, the top plate 12 is provided with a rotating insert 123 inserted into the mounting sleeve 113, the storage cavity 1121 is provided with a plurality of fun beads 5, the bottom plate 11 is provided with a primary extraction hole 114 adapted to the shape and size of the fun beads 5, the bottom plate 11 is provided with a control cavity communicating with the primary extraction hole 114 below the primary extraction hole 114, the control cavity is provided with a control component 6 that rotates synchronously with the top plate 12, the control component 6 is provided with a control groove 61 that allows the fun beads 5 to enter through the vertically extending upper edge, the bottom plate 11 is provided with a secondary extraction hole 115 communicating with the control cavity below the storage cavity 1121, when the top plate 12 is in the closed position 41, the control groove 61 is located on the extension trajectory of the primary extraction hole 114, when the top plate 12 is in the open position When the top plate is in the closed position 41, the control slot 61 is located on the extension trajectory of the secondary take-out hole 115. The top plate 12 is provided with a through hole 124 that communicates with the storage cavity 1121. Therefore, the top plate 12 and the bottom plate 11 are rotated and installed by the insertion of the mounting sleeve 113 and the mounting insert. When the top plate 12 is in the closed position 41, the fun bead 5 will pass through the primary take-out hole 114 under the action of gravity and enter the control slot 61. Then, when the top plate 12 rotates from the closed position 41 to the open position 42, the control component 6 drives the fun bead 5 in the control slot 61 to rotate. When the top plate 12 moves to the open position 42, the control slot 61 and the secondary take-out hole 115 are aligned, thereby realizing the removal of the fun bead 5. The linkage opening and closing improves the fun of the packaging box. The removed fun bead 5 can return to the storage cavity 1121 through the through hole 124 to form a take-out and put-out cycle.

[0049] Furthermore, in this embodiment, the mounting sleeve 113 is provided with a bead return cavity 1131 and a bead discharge cavity 1132, which are isolated from each other, located below the rotating insert 123. The primary extraction hole 114 is located in the bead discharge cavity 1132. The rotating insert 123 is provided with an isolation cavity 1231. The insertion hole 124 is located above the isolation cavity 1231. The top plate 12 is provided with an L-shaped tube 1232 for connecting the insertion hole 124 and the isolation cavity 1231. The lower end of the rotating insert 123 is provided with a bead return hole 1233 that connects the bead return cavity 1131 and the isolation cavity 1231. The lower end of the mounting sleeve 113 is provided with a bead return opening 1133 that connects the storage groove and the bead return cavity 1131. The lower end of the mounting sleeve 113 is provided with a bead discharge opening that connects the storage groove and the bead discharge cavity 1132. The bead opening 1134 and the orientation of the return bead opening 1133 are perpendicular to the orientation of the exit bead opening 1134. Therefore, 1. the fun bead 5 returning from the insertion hole 124 needs to pass through the L-shaped tube 1232 into the isolation cavity 1231, and then through the return bead hole 1233 into the return bead cavity 1131, and finally through the return bead opening 1133 into the storage cavity 1121. This makes it easy for the fun bead 5 to enter the storage cavity 1121 from the insertion hole 124, and difficult for it to come out in the opposite direction; 2. The return bead cavity 1131 and the exit bead cavity 1132 are mutually isolated, and the return bead opening 1133 and the exit bead opening 1134 are perpendicular to each other. Therefore, the fun bead 5 entering the storage cavity 1121 from the return bead cavity 1131 is not easy to quickly enter the exit bead cavity 1132, reducing the rapid rejection of the newly returned fun bead 5 and increasing the diversity of the rejected fun bead 5.

[0050] In this embodiment, the control component 6 is fixedly installed to the mounting post by means of threads.
