[0031] To make the purpose, technical solutions, and advantages of this application more clear, the technical solutions of this application will be described in detail below. Obviously, the embodiments described are only some of the embodiments of this application, rather than all of them. Based on the embodiments in this application, all other implementation methods obtained by ordinary technicians in this field without making any creative work are within the scope of protection of this application.
[0032] As described in the background art, in order to reduce the risk of damage to items during logistics and transportation, relevant components for cushioning and protection are usually set in the packaging of the items (such as packaging boxes, packaging boxes, etc.). In the related art, such components are generally made of foam materials (such as EPS, EPP, EVA, etc.) through mold shaping, fit to the items or containers, and limit the items or containers in the packaging. In this way, when subjected to external impact and vibration, the foam material with a certain thickness can absorb energy to achieve the effect of cushioning and protection. With this existing buffering implementation method, the mold cost for the production of buffer components is high; on the other hand, foam materials are not environmentally friendly, easy to disperse, and difficult to collect in a centralized manner. Some countries have begun to implement relevant laws and regulations to restrict their application.
[0033] To address this, the present application proposes a packaging buffer structure that adopts a specific structural setting and is based on the application of structural plate materials for packaging. While satisfying the buffering function, it effectively reduces the cost of mold production.
[0034] like Figures 1 to 4 As shown, in one embodiment, the packaging buffer structure proposed in this application is composed of a main support block 100, a buffering and laminating support block 200, and a plane fixed limit block 300;
[0035] In this embodiment, Figure 2 As shown, the main support block 100 is composed of at least one U-shaped support member 110 ( Figure 2 The main support block shown in FIG is composed of three U-shaped support members bonded together). Figure 4 As shown, a plurality of rectangular holes 310 are provided on the plane fixed limit block 300, so that the main support block can be combined with the plane fixed limit block in a twenty-shaped insertion manner. Figure 1As shown, it is easy to understand that the twenty-shaped insertion method here refers to the insertion method in which each folded edge of the main support block passes through the corresponding rectangular hole from the bottom of the flat fixed block and emerges from the top of the main support block;
[0036] In this embodiment, the buffering and laminating support block 200 and the U-shaped support member 110 are both folded and processed from a structural plate for packaging. Figure 2 As shown, a first slot 111 is vertically provided on the folded edge of the U-shaped support member 110. Figure 3 As shown, the buffer laminating support block 200 is a comb-like component, and the outer side surface of the comb body of the component ( Figure 3 The upper surface of the component in the middle figure is the contact surface with the supported and limited object. The second slots 210 corresponding to the first slots are vertically provided on the folded edge of the comb portion of the component. Based on the cross-fitting fit between the corresponding first slots and the second slots, the combination of the buffering and laminating support block 200 and the main support block 100 is realized;
[0037] Combine Figure 1 As shown, it is easy to understand that the cross-fitting here means that Figure 3 The second slots on the comb teeth of the buffering and fitting support block 200 shown in the figure are correspondingly inserted and matched with the corresponding first slots on the main support block 100, so that the folding edges of the buffering and fitting support block and the main support block form a cross-shaped (or longitude and latitude cross-shaped) support structure, and then combined to form a structure as shown in the figure. Figure 1 The packaging cushioning structure shown.
[0038] In the technical solution of the present application, structural plates for packaging are folded into structural components, and a plug-in combination method is used to form the buffer structure described above. Compared with the existing technology, the buffer structure of this implementation method can effectively reduce the mold cost in the production process.
[0039] In some embodiments, as Figure 2 and Figure 5 As shown, in the buffering and fitting support block 200, the outer side surface of the comb body (or the supporting and fitting surface) of the component adopts a special-shaped fitting design according to the requirements of support and limiting. Here, the special-shaped fitting design refers to designing the supporting and fitting surface into a corresponding shape according to the actual scene requirements to increase the buffering contact area and enhance the support and buffering performance of the structure;
[0040] Specifically, in actual implementation, the buffer laminating support block is folded from a strip-like structural plate for packaging. The special-shaped laminating design can be achieved based on the customized adjustment of the crease spacing, fold line angle, and crease angle during the folding process. For example, the curvature of the laminating surface in one direction can be customized by the crease spacing and fold line angle, and the crease angle (the angle between the crease line and the horizontal, such as Figure 5 B in the middle figure) to customize the degree of inclination in the other downward direction. In addition, it is easy to understand that in actual production, the height of the fold edge (or supporting edge) can also be customized based on the control of the crease spacing.
[0041] Furthermore, the special-shaped fitting design here also includes avoidance design (such as Figure 2 A in the figure) to cope with the uneven contact surface in practice.
[0042] In some embodiments, based on the special-shaped fitting design adopted by the buffer fitting support block, the distal edge contours of the folded edges of various U-shaped support members in the main support block are set to a shape that matches it, such as Figure 2 The shape of the folded edge in the opening direction of the first slot 111;
[0043] Correspondingly, in order to meet the stability requirements of the support, the distal edges of the folded edges constituting the comb teeth of the component in the buffer fitting support block are designed to be horizontally flush, such as Figure 3 and Figure 5 The shape design of the folded edge in the opening direction of the second slot 210;
[0044] And it is understood that for each corresponding first slot and second slot (that is, the two slots corresponding to the cross insertion), the sum of the slot depth dimensions of the two slots is equal to the distance length dimension between the inner side surface of the comb body of the buffer fitting support block and the upper side surface of the plane fixed limit block at that location (that is, at the positions corresponding to the two slots), that is, by ensuring this slot depth relationship during manufacturing and processing, the structural stability after the insertion and assembly is guaranteed.
[0045] Furthermore, for the convenience of manufacturing and implementation, for each corresponding first slot and second slot, as shown in FIG. Figure 5 As shown, the depths of the second slots are the same.
[0046] In some embodiments, if the weight of the contents is high and the cushioning requirement is large, an appropriate reinforcement structure is required. For example, to enhance the support strength, the cushioning fitting support block and / or the U-shaped support member are folded and processed by at least one layer of structural plate for packaging; optionally, all the supporting ribs (corresponding to the folded edges) can be changed to a double-layer or multi-layer reinforcement structure, that is, the support and cushioning effect can be increased by folding the entire single layer and partially pasting one or more layers of plate material.
[0047] In addition, since the structure itself is a grid structure formed by the intersection of warp and weft vertical reinforcements, there is a certain space within the grid. In actual implementation, the interior of the space can be filled with air columns, honeycomb cardboard, etc. as needed to provide cushioning / support reinforcement.
[0048] In some embodiments, if the surface to be supported is higher, in order to meet the height requirement, the height of the main support block can be adjusted and the planar fixed limit block can be made of multiple planar sub-plates with the same structure stacked together, and each planar sub-plate is made of a structural plate for packaging.
[0049] In addition, it is easy to understand that in the above embodiments, the packaging structural board used is corrugated cardboard or plastic hollow board, both of which can meet the structural strength and processing performance requirements and do not have the environmental protection problems of foam materials.
[0050] It is easy to understand that in scenarios where moisture resistance is required, the packaging structural board is preferably a plastic hollow board. The packaging buffer structure in this embodiment has the following advantages:
[0051] ①Moisture-proof and waterproof, recyclable and reusable;
[0052] ② The plug-in structure has strong support and, due to the hollow structure of the hollow board and the elasticity of the material itself, has a certain buffering effect; the plug-in structure involves multiple slots, and the structural components are relatively fixed but can move within a certain limit range, so the structure itself has a certain degree of mobility. When subjected to impact, the structure can play a certain buffering function.
[0053] ③ The mold cost is relatively low, which is conducive to rapid iteration;
[0054] ④ Based on actual needs, reinforced structure and internal filling reinforced structure can be adopted, which has good flexibility.
[0055] In one embodiment, the present application further proposes a packaging piece (such as a packaging box, a packaging case, etc.), which uses the packaging buffer structure described in the above embodiment.
[0056] The above description is merely a preferred embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by anyone familiar with the technology within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
