Description

Technical Field

[0001] This utility model relates to the field of egg packaging technology, specifically to a cushioning and protective device for egg packaging. Background Technology

[0002] Eggs are a common food in people's daily lives. Before leaving the factory, they are usually packaged and transported in pallets. The pallets are generally equipped with multiple egg nests to hold the eggs. However, they are still lacking in protection and cushioning performance. Most existing pallets can only provide simple support for the bottom of the eggs or roughly limit the lateral movement. Their egg nest structure is often too rigid, and it is difficult to effectively absorb the impact energy from all directions when encountering large bumps during transportation. On the other hand, some solutions that use flexible materials can provide some cushioning, but they have poor support and are easily deformed when stacked or squeezed, resulting in the eggs breaking.

[0003] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a cushioning and protective device for egg packaging to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A cushioning and protective device for egg packaging includes a tray with a cover hinged to its top edge. The tray surface has multiple sets of egg pockets for holding eggs. The inner side of the cover has corresponding limiting holes. Protective cushioning components are provided on the surfaces of the tray and cover. These components include a bottom protective structure at the bottom of each egg pocket; a side protective structure on the inner wall of each egg pocket; and a top protective structure inside the limiting holes. When the cover is closed on the tray, the bottom, side, and top protective structures together provide coordinated cushioning and limiting for the top, sides, and bottom of a single egg.

[0007] Preferably, the bottom protective structure includes a top plate, the bottom of which is fixedly connected to a micro-buffer spring. The bottom protective structure is movably connected to the inside of the egg tray. Through the cooperation of the top plate and the micro-buffer spring, the bottom protective structure forms a highly efficient elastic cushioning system. This effectively absorbs and dissipates the impact energy from the bottom of the egg, isolating the egg from the bottom of the hard tray and preventing the egg from breaking due to direct impact with a hard object during vertical vibration or drop. It has the beneficial effects of significant cushioning effect and high reliability.

[0008] Preferably, the bottom of the miniature buffer spring is provided with a base plate, and the bottom of the base plate is provided with a snap-fit ​​structure, specifically a snap-fit ​​block. The bottom of the egg nest has an installation opening, and the surface of the installation opening has a slot structure that matches the snap-fit ​​block. The bottom protection structure achieves a detachable connection by the snap-fit ​​structure at the bottom of the base plate and the slot at the bottom of the egg nest. This allows the buffer unit composed of the top plate, miniature buffer spring, and base plate to be easily installed and replaced. When some parts age or are damaged due to long-term use, it is not necessary to replace the entire tray. This has the beneficial effects of facilitating maintenance, extending product lifespan, and reducing user costs.

[0009] Preferably, the side protection structure includes a flexible protective layer, and a sponge layer is fixedly connected to the inner wall of the flexible protective layer. The side protection structure provides comprehensive protection for the side of the egg through the dual flexible design of the flexible protective layer and the sponge layer. This effectively absorbs the horizontal impact and vibration generated by the egg during transportation by utilizing the soft properties of the sponge layer, and disperses the contact stress through the flexible protective layer. It has the beneficial effect of excellent lateral buffering performance and can effectively prevent the egg from colliding with the hard inner wall of the eggshell.

[0010] Preferably, both the outer wall of the flexible protective layer and the inner wall of the egg nest are provided with Velcro structures, and the sizes of the two sets of Velcro structures are matched. The side protection structure is fixed by the Velcro structures provided on the flexible protective layer and the inner wall of the egg nest. This realizes the detachable connection of the side protection structure, which allows the user to easily remove the flexible protective layer and the sponge layer from the egg nest for cleaning or replacement. It has the beneficial effects of easy cleaning, maintaining hygiene and convenient maintenance.

[0011] Preferably, the top protective structure includes flexible buffer pillars disposed inside the limiting hole. An elastic buffer ball is fixedly connected to the top of each flexible buffer pillar. Multiple sets of flexible buffer pillars are arranged in a circumferential array on the inner wall of the limiting hole. The top protective structure, through the circumferentially arrayed flexible buffer pillars and the elastic buffer balls at their ends, forms multi-point flexible contact with the top of the egg when the lid is closed. This transforms the point pressure of a traditional lid into a multi-directional elastic holding force, preventing damage to the top of the egg and limiting the egg's movement during transportation. It has the beneficial effects of dispersing pressure, dynamic limiting, and effectively protecting the top of the egg.

[0012] Preferably, a sealing groove is provided at the top edge of the tray, and a sealing strip is fixedly connected to the inner edge of the cover. The tray and the edge of the cover form a sealed moisture-proof structure through the cooperation of the sealing strip and the sealing groove. This effectively prevents external moisture from entering the interior of the tray, preventing hygroscopic cushioning materials such as the sponge layer from becoming damp and moldy. It also provides a more stable and clean storage environment for eggs, and has the beneficial effects of moisture and dust prevention and extending the life of internal cushioning components.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The protective buffer components provide comprehensive protection for eggs from multiple directions, absorbing vibration energy. This all-round collaborative buffer and limiting design ensures that eggs are well protected during transportation, greatly reducing the breakage rate and safeguarding the safe transportation of eggs.

[0015] 2. The bottom protective structure features a snap-fit ​​mechanism at the bottom of the base plate that engages with the slot at the bottom of the egg nest, enabling a detachable connection. When the micro-buffer springs age or the top plate wears, the entire tray does not need to be replaced; only the corresponding parts need to be replaced, reducing maintenance costs and extending the tray's lifespan. The flexible protective layer of the side protective structure is fixed to the inner wall of the egg nest via Velcro, allowing the flexible protective layer and sponge layer to be removed for cleaning or replacement at any time.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] According to an embodiment of the present invention, a cushioning and protective device for egg packaging is provided.

[0025] Example 1;

[0026] like Figure 1-5 As shown, the egg packaging cushioning and protective device according to an embodiment of the present invention includes a tray 1. A cover plate 2 is hinged to the top edge of the tray 1 via a hinge. Multiple sets of egg sockets 3 for accommodating eggs are formed on the surface of the tray 1. The inner side of the cover plate 2 is provided with limiting holes 4 corresponding to the egg sockets 3. Protective cushioning components are provided on the surfaces of the tray 1 and the cover plate 2. The protective cushioning components include a bottom protective structure 5, which is provided at the bottom of the egg sockets 3; a side protective structure, which is provided on the inner side wall of the egg sockets 3; and a top protective structure, which is provided inside the limiting holes 4. When the cover plate 2 is closed on the tray 1, the bottom protective structure 5, the side protective structure and the top protective structure together constitute a coordinated cushioning and limiting of the top, sides and bottom of a single egg.

[0027] In this embodiment, the bottom protective structure 5 includes a top plate 8, with a miniature buffer spring 7 fixedly connected to the bottom of the top plate 8. The bottom protective structure 5 is movably connected to the inside of the egg tray 3. Through the cooperation of the top plate 8 and the miniature buffer spring 7, the bottom protective structure 5 forms a highly efficient elastic buffer system. This effectively absorbs and dissipates the impact energy from the bottom of the egg, isolating the egg from the bottom of the hard tray and preventing the egg from breaking due to direct impact with hard objects when vertically vibrating or falling. It has the beneficial effects of significant buffering effect and high reliability.

[0028] In this embodiment, a base plate 6 is provided at the bottom of the miniature buffer spring 7, and a snap-fit ​​structure 9 is provided at the bottom of the base plate 6. The snap-fit ​​structure 9 is specifically a snap-fit ​​block. An installation port is provided at the bottom of the egg nest 3, and a slot structure matching the snap-fit ​​block is provided on the surface of the installation port. The bottom protective structure 5 achieves a detachable connection by the interplay between the snap-fit ​​structure 9 at the bottom of the base plate 6 and the slot at the bottom of the egg nest 3. This allows the buffer unit composed of the top plate 8, the miniature buffer spring 7, and the base plate 6 to be easily installed and replaced. When some parts age or are damaged due to long-term use, it is not necessary to replace the entire tray. This has the beneficial effects of facilitating maintenance, extending product lifespan, and reducing user costs.

[0029] In this embodiment, the side protection structure includes a flexible protective layer 10, and a sponge layer 11 is fixedly connected to the inner wall of the flexible protective layer 10. The side protection structure provides comprehensive protection for the side of the egg through the dual flexible design of the flexible protective layer 10 and the sponge layer 11. This effectively absorbs the horizontal impact and vibration generated by the egg during transportation by utilizing the soft properties of the sponge layer 11, and disperses the contact stress through the flexible protective layer 10. It has the beneficial effect of excellent lateral buffering performance and can effectively prevent the egg from colliding with the inner wall of the hard egg socket 3.

[0030] In this embodiment, both the outer wall of the flexible protective layer 10 and the inner wall of the egg nest 3 are provided with Velcro structures 12, and the sizes of the two sets of Velcro structures 12 are matched. The side protection structure is fixed by the Velcro structures 12 provided on the flexible protective layer 10 and the inner wall of the egg nest 3. This realizes the detachable connection of the side protection structure, so that the user can easily remove the flexible protective layer 10 and the sponge layer 11 from the egg nest 3 for cleaning or replacement. It has the beneficial effects of easy cleaning, maintaining hygiene and convenient maintenance.

[0031] In this embodiment, the top protective structure includes flexible buffer pillars 13 disposed inside the limiting hole 4. Elastic buffer balls 14 are fixedly connected to the top of each flexible buffer pillar 13. Multiple sets of flexible buffer pillars are arranged in a circumferential array on the inner wall of the limiting hole 4. The top protective structure, through the circumferentially arrayed flexible buffer pillars 13 and the elastic buffer balls 14 at their ends, forms multiple points of flexible contact with the top of the egg when the lid is closed. This transforms the point pressure of the traditional lid 2 into elastic holding force in multiple directions, preventing damage to the top of the egg and limiting the egg's movement during transportation. It has the beneficial effects of dispersing pressure, dynamic limiting, and effectively protecting the top of the egg.

[0032] In this embodiment, a sealing groove 15 is provided at the top edge of the tray 1, and a sealing strip 16 is fixedly connected to the inner edge of the cover plate 2. The edges of the tray 1 and the cover plate 2 form a sealed moisture-proof structure through the cooperation of the sealing strip 16 and the sealing groove 15. This effectively prevents external moisture from entering the interior of the tray, prevents the hygroscopic cushioning materials such as the sponge layer 11 from becoming damp and moldy, and also provides a more stable and clean storage environment for the eggs, with the beneficial effects of moisture and dust prevention and extending the life of the internal cushioning components.

[0033] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0034] In practical application, it is first necessary to confirm that the bottom protective structure 5 of the egg nest 3 in the tray 1 has been installed by the snap-fit ​​structure 9, and that the side protective structure containing the flexible protective layer 10 and the sponge layer 11 is fixed to the inner side wall of the egg nest 3 by the Velcro structure 12. Then, eggs are placed one by one into the egg nest 3, so that the bottom of the egg contacts the top plate 8 of the bottom protective structure 5 and the sides are wrapped by the flexible protective layer 10 and the sponge layer 11, completing the initial support and limiting. Next, the cover plate 2 is flipped around the hinge toward the tray 1, so that the limiting hole 4 on the inner side of the cover plate 2 corresponds precisely with the egg and is completely closed. At this time, the flexible buffer in the circumferential array inside the limiting hole 4 is activated. The column 13 and the top elastic buffer ball 14 will contact the top of the egg, and the sealing strip 16 on the edge of the cover plate 2 will also be embedded in the sealing groove 15 on the top of the tray 1, forming a sealed space for all-round coordinated protection to buffer the impact of transportation. During subsequent maintenance, if the miniature buffer spring 7 of the bottom protective structure 5 is aged or the top plate 8 is damaged, the buckle structure 9 can be removed to remove the entire bottom protective structure 5 for replacement. If the sponge layer 11 of the side protective structure is damp or the flexible protective layer 10 is damaged, the Velcro structure 12 can be unfastened to remove it for cleaning or replacement. After maintenance, it can be reassembled in the initial manner to ensure that the device continues to play a good buffering and protective role.

[0035] In summary, by utilizing the above-mentioned technical solution of this utility model, the protective buffer components can provide comprehensive coverage for eggs from multiple directions, absorbing vibration energy. This all-round collaborative buffering and limiting design ensures the eggs are fully protected during transportation, greatly reducing the breakage rate and safeguarding the safe transport of eggs. The bottom protective structure 5 and the snap-fit ​​structure 9 at the bottom of the bottom plate 6 cooperate with the bottom slot of the egg nest 3 to achieve a detachable connection. When the micro-buffer spring 7 ages or the top plate 8 wears, it is not necessary to replace the entire tray 1; only the corresponding parts need to be replaced, reducing maintenance costs and extending the service life of the tray 1. The flexible protective layer 10 of the side protective structure is fixed to the inner wall of the egg nest 3 by the Velcro structure 12, allowing the flexible protective layer 10 and the sponge layer 11 to be removed at any time for cleaning or replacement.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
