Description

Technical Field

[0001] This utility model belongs to the field of green packaging technology, and in particular relates to a reusable double-layer green packaging. Background Technology

[0002] With the popularization of environmental protection concepts, reusable green packaging is gradually replacing single-use packaging, becoming a development trend in the packaging industry. Although the double-layer packaging currently on the market can achieve basic protection and reuse functions through its inner and outer layer structure, there is still room for improvement in terms of sealing performance, ease of operation, material compatibility, and recycling efficiency.

[0003] A search revealed an existing patent (authorization announcement number: CN221368243U) disclosing a reusable double-layer green packaging, relating to the field of green packaging. The packaging includes a box body, a dustproof component, and a movable cover. The outer side of the box body is provided with a protective shell, and the inner side of the protective shell is fixedly connected to a fixing shell. Furthermore, the inner side of the fixing shell is provided with a support component. This reusable double-layer green packaging, by incorporating the support and drying components, provides stable support for the green packaging during use, improving its compressive strength and preventing collapse. It also divides the internal space of the green packaging, allowing for more organized placement of items. Simultaneously, it dries the interior of the green packaging to prevent moisture damage, extending the lifespan of the green packaging and facilitating its reuse by staff.

[0004] However, the above structure still has shortcomings. Its opening and closing relies on the traditional cover plate structure and does not have a convenient locking and unlocking mechanism. Each opening and closing requires multiple operations. Especially in logistics and transportation scenarios, the efficiency is low when opening or closing frequently, and the locking stability is insufficient, which can easily lead to the problem of the cover plate loosening during transportation. In addition, its inner and outer layers and various components are mostly made of a single material or fixed connection structure, making it difficult to quickly disassemble components of different materials.

[0005] Therefore, it is necessary to provide a new reusable double-layer green packaging to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical problem solved by this utility model is to provide a reusable double-layer green packaging that is easy to open and close, provides adequate protection, and is easy to classify and recycle.

[0007] To solve the above-mentioned technical problems, the reusable double-layer green packaging provided by this utility model includes: an outer shell, an outer cover one and an outer cover two, an inner liner placed inside the outer shell, a soft pad fixedly adhered to the inner bottom surface of the outer shell, a limit frame fixedly connected to the inner bottom surface of the outer shell, and a quick opening and closing mechanism provided on the outer shell.

[0008] The quick-opening and closing mechanism includes two C-shaped blocks, both of which are fixedly connected to the outer wall of the outer shell. The bottom surfaces of the first and second outer covers are each fixedly connected to hook-shaped blocks corresponding to the C-shaped blocks. An adjusting nut is rotatably installed on the C-shaped block. A threaded post is threadedly connected to the inner wall of the adjusting nut. A circular plate is fixedly connected to one end of the threaded post. A spring is fixedly connected to one side surface of the circular plate. A top block is fixedly connected to the other end of the spring. The size of the top block is adapted to the size of the hook-shaped block.

[0009] As a further embodiment of this utility model, limiting strips are fixedly connected to both sides of the top block, and the inner wall of the C-shaped block is provided with a sliding groove corresponding to the two limiting strips.

[0010] As a further embodiment of this utility model, four insert posts are fixedly connected to one side surface of the outer cover one, and slots corresponding to the four insert posts are opened on the outer cover two.

[0011] As a further embodiment of this utility model, an inner liner cover is placed on the inner liner, and a side groove is formed on the outer wall of the inner liner cover. Inserts that are adapted to the side groove are fixedly connected to the outer cover one and the outer cover two.

[0012] As a further embodiment of this utility model, the bottom surface of the inner liner cover is provided with an inner groove adapted to the inner liner, and the bottom surfaces of the outer cover one and outer cover two are provided with outer grooves adapted to the outer shell.

[0013] As a further embodiment of this utility model, both the inner liner and the inner liner cover are made of food-grade PLA resin, and the outer shell is made of PET material.

[0014] Compared with related technologies, the reusable double-layer green packaging provided by this utility model has the following beneficial effects:

[0015] 1. This utility model achieves both the safety and hygiene of the food contact parts and the strength protection of the non-contact parts by differentiating the materials of the inner liner and the outer shell and detachable connection structure of the side groove and the insert strip. It can also quickly separate parts of different materials during recycling, and is equipped with a quick opening and closing mechanism to ensure the convenience of repeated use.

[0016] 2. This utility model achieves precise positioning of the inner liner through the limiting frame, cushions collision damage with soft pads, and allows insulation cloth to be placed in the gap between the inner liner and the outer shell to maintain food temperature, further optimizing the protective and practical performance of the packaging.

Detailed Implementation

[0023] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 This is a schematic diagram of the overall structure of the reusable double-layer green packaging of this utility model; Figure 2 This is a schematic diagram of the inner liner structure of the reusable double-layer green packaging of this utility model; Figure 3 This is a schematic diagram of the quick-opening and closing mechanism of the reusable double-layer green packaging of this utility model; Figure 4 A schematic diagram of the inner lid structure of the reusable double-layer green packaging provided by this utility model. The reusable double-layer green packaging includes: an outer shell 1, an outer cover 1 2, and an outer cover 2 3. An inner liner 4 is placed inside the outer shell 1. A soft pad 5 is fixedly adhered to the inner bottom surface of the outer shell 1. A limiting frame 6 is fixedly connected to the inner bottom surface of the outer shell 1. A quick-opening and closing mechanism is provided on the outer shell 1.

[0024] The quick-opening and closing mechanism includes two C-shaped blocks 7, both of which are fixedly connected to the outer wall of the outer casing 1. The bottom surfaces of the outer cover 1 2 and the outer cover 2 3 are both fixedly connected to hook-shaped blocks 8 corresponding to the C-shaped blocks 7. An adjusting nut 9 is rotatably installed on the C-shaped block 7. A threaded post 10 is threadedly connected to the inner wall of the adjusting nut 9. A circular plate 11 is fixedly connected to one end of the threaded post 10. A spring 12 is fixedly connected to one side surface of the circular plate 11. A top block 13 is fixedly connected to the other end of the spring 12. The size of the top block 13 is adapted to the size of the hook-shaped block 8.

[0025] like Figure 3 As shown, limit strips 14 are fixedly connected to both sides of the top block 13, and the inner wall of the shaped block 7 is provided with a sliding groove corresponding to the two limit strips 14.

[0026] By using the limit bar 14 in conjunction with the slide groove, the movement direction of the top block 13 can be restricted, preventing the top block 13 from shifting during movement and ensuring the accuracy of the fit between the top block 13 and the hook block 8.

[0027] like Figure 4 As shown, four inserts 15 are fixedly connected to one side surface of the outer cover 2, and slots corresponding to the four inserts 15 are opened on the outer cover 3.

[0028] By using the insertion post 15 and the slot to cooperate, the tightness of the connection between the outer cover 1 2 and the outer cover 2 3 can be enhanced, preventing them from becoming loose or misaligned when closed, thus improving the stability of the overall structure.

[0029] like Figure 4 As shown, an inner liner cover 16 is placed on the inner liner 4. A side groove 17 is provided on the outer wall of the inner liner cover 16. Insert strips 18 that are adapted to the side groove 17 are fixedly connected to the outer cover 2 and the outer cover 3.

[0030] The combination of the side groove 17 and the insert 18 facilitates the subsequent separate recycling process.

[0031] like Figure 4 As shown, the bottom surface of the inner liner cover 16 is provided with an inner groove 19 that is adapted to the inner liner 4, and the bottom surfaces of the outer cover 1 2 and the outer cover 2 3 are provided with outer grooves 20 that are adapted to the outer shell 1.

[0032] By adapting the inner groove 19 to the inner liner 4 and the outer groove 20 to the outer shell 1, the sealing performance between the inner liner cover 16 and the inner liner 4, and between the outer cover and the outer shell 1, can be improved, and the generation of gaps can be reduced.

[0033] like Figure 1As shown, the inner liner 4 and the inner liner cover 16 are both made of food-grade PLA resin, and the outer shell 1 is made of PET material.

[0034] By using food-grade PLA resin to make the inner liner 4 and inner liner cover 16, the safety of contact with food can be guaranteed; while the outer shell 1 is made of PET material, which helps to improve the strength and durability of the overall structure.

[0035] The working principle of the reusable double-layer green packaging provided by this utility model is as follows:

[0036] First step: When using, first put the items to be stored into the inner liner 4, and cover the inner liner lid 16 so that the inner groove 19 of the inner liner lid 16 fits precisely with the inner liner 4 to ensure the airtightness of the inner liner 4. Then put the inner liner 4 containing the items into the outer shell 1 and place it in the limiting frame 6. Use the limiting frame 6 to position it. At the same time, the soft pad 5 can form a buffer protection for the liner. Then put the heat insulation cloth in the gap between the inner liner 4 and the outer shell 1 to maintain the temperature of the food in the inner liner 4.

[0037] Second step: Close the outer cover 1 2 and outer cover 2 3, so that the insert 15 on the outer cover 1 2 is inserted into the corresponding slot of the outer cover 2 3. At the same time, the outer groove 20 is adapted and fitted to the outer shell 1. The insert 18 is embedded in the side groove 17 of the inner liner cover 16. Then, the hook block 8 is aligned with the tang-shaped block 7 and the outer cover 1 2 and outer cover 2 3 are pressed down. Then the hook block 8 presses the top block 13. The top block 13 moves backward until the hook block 8 reaches the designated position. The pressed top block 13 returns to its original position under the rebound of the spring 12. At this time, the top block 13 can limit the position of the hook block 8, thereby fixing the outer cover 1 2 and outer cover 2 3.

[0038] Third step: Then rotate the adjusting nut 9 to move the threaded column 10, thereby moving the top block 13 away from the hook block 8, releasing the restriction on the hook block 8. When recycling, the inner liner 4 and the inner liner cover 16 can be taken out separately for easy sorting and recycling.
