Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, and in particular to a zongzi (sticky rice dumpling) packaging box with multiple protective functions. Background Technology

[0002] After production, zongzi need to be sealed and packaged, then placed in special packaging boxes before being transported and sold. In order to improve the protection and appearance of zongzi, existing packaging boxes are generally made of rigid cardboard.

[0003] Existing packaging boxes for zongzi typically have side panels, with multiple smaller inner boxes inside the outer box. However, the existing outer box lacks a structure to secure the inner boxes when they are inserted. This means that when the outer box is bumped or shaken violently, the inner boxes may collide with the inner wall of the outer box, potentially causing them to loosen or become damaged, affecting the overall aesthetics and integrity of the packaging. Furthermore, the outer box usually uses a magnetic locking mechanism for closure, which is unstable and prone to detachment upon significant impact, leading to the inner boxes falling out. There is room for improvement in this approach. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a zongzi packaging box with multiple protective functions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-functional protective packaging box for zongzi (sticky rice dumplings) includes a main body. A folded cardboard is fixedly connected to the lower surface of the main body, and a locking block is fixedly connected to the front of the folded cardboard. Two limiting holes are formed on the surface of the locking block. An inner box is fixedly connected to the inner bottom wall of the main body. A slot is formed on the upper surface of the inner box, and six secondary packaging boxes are inserted into the inner wall of the slot. Positioning grooves are formed on both the left and right sides of each secondary packaging box. A sliding groove is formed on the upper surface of the inner box, and a positioning component, including a pushing cardboard, is slidably connected to the inner wall of the sliding groove. An active cavity is formed inside the inner box at a position corresponding to the two sliding grooves. Three through holes are formed on the inner wall of the active cavity near the slot. Strip cardboard is slidably connected to the inner wall of the active cavity, and three positioning blocks are fixedly connected to the opposite faces of the two strip cardboards. A cylindrical airbag is fixedly connected to the inner wall of the active cavity. An air cylinder is fixedly connected to the upper surface of the inner box at a position corresponding to the two sliding grooves. A sealing cap is threaded to the top of the air cylinder, and a connecting hose is connected to the bottom of the air cylinder.

[0007] Preferably, the lower surfaces of the two pushing cardboards extend into the interior of the two movable cavities and are fixedly connected to the upper surfaces of the two strip cardboards, and the positioning blocks are adapted to the through holes and positioning grooves.

[0008] Preferably, the end of the connecting hose away from the inflation cylinder extends into the interior of the active cavity and communicates with the interior of the cylindrical airbag.

[0009] Preferably, the front of the packaging box body is provided with a locking hole that matches the locking block. Inside the packaging box body, two strip-shaped cavities are provided at positions corresponding to the locking hole. The inner walls of the strip-shaped cavities are slidably connected to movable plates. Positioning rods are fixedly connected to the opposite sides of the two movable plates. The opposite ends of the two positioning rods extend into the interior of the locking hole, and the positioning rods are matched with the limiting holes.

[0010] Preferably, each of the two movable plates has a movable rod fixedly connected to its opposite side, and each movable rod has a spring sleeved on its surface. The opposite ends of the two springs overlap with the opposite sides of the two movable plates, and the ends of the two springs away from the movable plates overlap with the inner walls of the two strip cavities.

[0011] Preferably, pull ropes are fixedly connected to the opposite ends of the two movable rods, and the ends of the two pull ropes away from the movable rods extend to the left and right sides of the packaging box body, respectively.

[0012] The beneficial effects of this utility model are as follows:

[0013] By incorporating the positioning components, the inflated cylindrical airbag presses the strip of cardboard firmly against the movable cavity during use, ensuring that the positioning block can be stably inserted into the positioning groove on the side of the secondary packaging box. This locks the position of the secondary packaging box in place, preventing it from detaching or becoming loose and damaged even if the main packaging box shakes or collides. This provides sufficient assurance for the aesthetics and integrity of the secondary packaging box. Furthermore, the positioning rod, moving plate, movable rod, spring, and pull rope allow the spring force to firmly insert the positioning rod into the limiting hole on the locking block surface during use, ensuring that the folded cardboard will not easily detach, thus providing good protection for the main packaging box.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example:

[0020] Reference Figure 1-3 A multi-functional protective packaging box for zongzi (sticky rice dumplings) includes a box body 1. A folded cardboard 2 is fixedly connected to the lower surface of the box body 1. A locking block 3 is fixedly connected to the front of the folded cardboard 2. Two limiting holes are formed on the surface of the locking block 3. An inner box 4 is fixedly connected to the inner bottom wall of the box body 1. A slot is formed on the upper surface of the inner box 4. Six secondary packaging boxes 5 are inserted into the inner wall of the slot. Positioning grooves 6 are formed on both the left and right sides of each secondary packaging box 5. A sliding groove is formed on the upper surface of the inner box 4. A positioning component is slidably connected to the inner wall of the sliding groove. The components include a push cardboard 7, an inner box 4 with movable cavities at positions corresponding to the two slides, three through holes at the inner wall of the movable cavities near the slots, a strip cardboard 8 slidably connected to the inner wall of the movable cavities, three positioning blocks 9 fixedly connected to the opposite sides of the two strip cardboard 8, a cylindrical airbag 10 fixedly connected to the inner wall of the movable cavities, an air cylinder 11 fixedly connected to the upper surface of the inner box 4 at positions corresponding to the two slides, a sealing cap 12 threadedly connected to the top of the air cylinder 11, and a connecting hose 13 connected to the bottom of the air cylinder 11.

[0021] The lower surfaces of the two push cardboard 7 extend into the interior of the two movable cavities and are fixedly connected to the upper surfaces of the two strip cardboard 8, and the positioning insert 9 is adapted to the through hole and the positioning groove 6. The end of the connecting hose 13 away from the air cylinder 11 extends into the interior of the movable cavity and is connected to the interior of the cylindrical airbag 10.

[0022] After the secondary packaging box 5 is inserted into the slot, the push cardboard 7 is used to move the strip cardboard 8 closer to the slot, so that the positioning block 9 is inserted into the positioning groove 6 on the side of the secondary packaging box 5. At this time, the inflation device is used to inflate the air cylinder 11. The gas enters the cylindrical air bag 10 through the air cylinder 11 and the connecting hose 13. After the cylindrical air bag 10 expands, it can press the strip cardboard 8 against the movable cavity, thereby ensuring that the positioning block 9 will not fall out of the positioning groove 6, ensuring the stability of the secondary packaging box 5 inside the packaging box body 1. Even if it shakes or is impacted, the secondary packaging box 5 will not be deformed or damaged.

[0023] The front of the packaging box body 1 is provided with a locking hole that matches the locking block 3. Inside the packaging box body 1, there are two strip-shaped cavities corresponding to the locking holes. The inner walls of the strip-shaped cavities are slidably connected to movable plates 14. Positioning rods 15 are fixedly connected to the opposite sides of the two movable plates 14. The opposite ends of the two positioning rods 15 extend into the interior of the locking holes and are matched with the limiting holes. Movable rods 16 are fixedly connected to the opposite back sides of the two movable plates 14. Springs 17 are sleeved on the surface of the two movable rods 16. The opposite ends of the two springs 17 overlap with the opposite back sides of the two movable plates 14, and the ends of the two springs 17 away from the movable plates 14 overlap with the inner walls of the two strip-shaped cavities. Pull ropes 18 are fixedly connected to the opposite ends of the two movable rods 16. The ends of the two pull ropes 18 away from the movable rods 16 extend to the left and right sides of the packaging box body 1.

[0024] After closing the folded cardboard 2, pull the two pull ropes 18 to both sides. The pull ropes 18 can drive the moving plate 14 to move to the side through the movable rod 16. The moving plate 14 can squeeze the spring 17 to deform it. At the same time, the moving plate 14 drives the positioning rod 15 to disengage from the locking hole. At this time, insert the locking block 3 into the locking hole, release the two pull ropes 18, and the reaction force generated by the spring 17 will drive the positioning rod 15 to insert into the locking hole and into the limiting hole on the surface of the locking block 3, thereby locking the locking block 3 and ensuring that the folded cardboard 2 will not be loosened due to shaking or collision, thus providing good protection for the packaging box body 1.

[0025] Working principle: First, place the rice dumpling into the secondary packaging box 5, then insert the secondary packaging box 5 into the slot. At this time, the pushing cardboard 7 moves the strip cardboard 8 closer to the slot until the positioning block 9 is inserted into the positioning groove 6, thus locking the position of the secondary packaging box 5 in the slot. Then, use the inflation device to align with the inflation cylinder 11 and inflate it. The gas enters the connecting hose 13 through the inflation cylinder 11 and then enters the cylindrical air bladder 10. After inflation, close the sealing cap 12. At this time, the cylindrical air bladder 10 is filled with gas and expands, pressing the strip cardboard 8 against the movable cavity, so that the strip cardboard 8 will not easily move within the movable cavity, thus ensuring the secondary packaging... The stability of box 5 within the slot improves the integrity of the secondary packaging box 5 and the protection of the zongzi inside. In addition, after closing the folded cardboard 2, pull the two pull ropes 18 to both sides. The pull ropes 18 drive the movable rod 16 to move to both sides. The movable rod 16 can drive the moving plate 14 to move to the side and squeeze the spring 17, causing the positioning rod 15 in the locking hole to disengage from the locking hole. At this time, insert the locking block 3 into the locking hole and release the pull ropes 18. At this time, the spring 17 generates a reaction force and drives the moving plate 14 back to its original position, so that the two positioning rods 15 can be inserted into the two limit holes on the surface of the locking block 3, ensuring the stability of the folded cardboard 2 after locking and preventing it from easily disengaging.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
