Description

Technical Field

[0001] This invention relates to the technical field of article packaging, specifically to a packaging structure for containing articles, and also provides a method for manufacturing the packaging structure. Background Technology

[0002] Current packaging technology for items with flat bottoms and irregular top shapes typically involves using a relatively large cubic corrugated cardboard box. After placing the item inside the box, foam or other filler materials are used to secure and protect the item in the empty space at the top. However, the foam needs to be custom-made to fit the item's shape, resulting in high production costs. Furthermore, this foam cannot be reused after transport, leading to material waste and environmental pollution. Additionally, when suitable foam is unavailable, entire pieces of foam must be cut to complete the filling process, resulting in low packaging efficiency. Therefore, there is an urgent need to develop a new, efficient packaging mechanism that effectively secures items while reducing material usage and environmental impact. Summary of the Invention

[0003] To address the aforementioned problems, the present invention provides a packaging structure for containing items, which effectively and reliably secures the items while reducing material usage and minimizing adverse environmental impact.

[0004] A packaging structure for containing articles, characterized in that it comprises: The platform includes a bottom support structure and a surrounding structure. The bottom support structure is surrounded by a surrounding structure, which together form a central placement cavity. And the mesh structure part, which includes a mesh hollow structure and locking edges on both sides, with locking edges provided on both sides of the mesh hollow structure; One pair of enclosure structures of the four surrounding structures are provided with alignment and locking mechanisms relative to the locking edges. After the item is placed in the placement cavity, the two locking edges of the mesh structure are respectively locked to the corresponding alignment and locking mechanisms. The mesh hollow structure covers the top of the item, and the bottom of the mesh hollow structure is arranged to mimic the convex shape of the item.

[0005] Its further features are: The mesh-like hollow structure is made of a planar material with a pre-set expandable mesh pattern on the surface of the planar material, which allows the mesh-like hollow structure to expand in three dimensions, forming a deformable structure for covering and fixing items. The grid pattern is specifically a hexagonal, fish-scale, or rhomboid pattern to ensure that the stretched structure has sufficient support strength and elastic recovery. The mesh pattern density of the mesh-like hollow structure can be adjusted according to the weight and shape of the packaged items, and the hollowing rate is controlled between 30% and 70%. The platform section and the mesh structure section are made of the same material, which reduces the amount of material used; The platform section and the mesh structure section are made of corrugated cardboard, composite paper, or plastic sheet. The bottom support structure and the surrounding enclosure structure of the platform are both made of flat materials that have been cut, folded and assembled to obtain the central placement cavity.

[0006] A method for manufacturing a packaging structure for containing articles, comprising the following steps: S1 prefabricates the corresponding planar material for the platform section. When in use, the bottom support structure and the surrounding structure are obtained by cutting, folding and assembling the planar material to form the middle placement cavity. S2 creates the mesh structure, and then the mesh hollow structure and locking edges are obtained on the flat material through machining.

[0007] Its further features are: The specific steps of step S2 are as follows: S201 pattern design: a pre-set, expandable grid pattern on a flat material. The grid pattern density is adjusted according to the weight and shape of the packaged items, and the perforation rate is controlled between 30% and 70%. The S202 cutting process selects the appropriate cutting method based on the material properties: for corrugated cardboard or composite paper, mechanical die-cutting is performed using a die-cutting machine or CNC flatbed knife to ensure neat cuts and maintain connection points; for plastic sheets (such as PET, PP, PLA), laser cutting or precision stamping processes are used to ensure high precision and minimize heat-affected zones. S203 connection retention: During the pattern cutting process, uncut connection points must be retained at key nodes where patterns intersect to ensure the overall continuity and tear resistance of the unfolded structure during the stretching process. After S204 molding and cutting, the mesh structure is in an initial flattened state. During use or packaging assembly, it can be unfolded into a three-dimensional support structure by bidirectional or axial stretching. The mesh-like hollow structure requires no additional bonding or assembly, has a certain degree of elastic recovery, and can cover and fix products and form a buffer area.

[0008] The packaging structure of this invention can be widely used in the packaging of various items that require fixation and protection, especially for the protective packaging of fragile items such as electronic products, glass products, and ceramic products during transportation and storage. With the increasing demand for environmentally friendly and efficient packaging, the packaging structure of this invention has broad application prospects, and its simple manufacturing method and excellent fixing effect make it highly competitive in the packaging industry.

[0010] A packaging structure for containing items, see Figures 1-2 It includes a platform section 10 and a mesh structure section 20; Platform section 10 includes a bottom support structure 11 and a surrounding structure 12. The bottom support structure 11 is surrounded by the surrounding structure 12, which together form a central placement cavity 13. The mesh structure portion 20 includes a mesh hollow structure 21 and two locking edges 22 on both sides. Locking edges 22 are respectively provided on both sides of the mesh hollow structure 21. One pair of the surrounding structures 12 are provided with a positioning and locking mechanism 121 relative to the locking edge. After the item 30 is placed in the placement cavity 13, the two locking edges 22 of the mesh structure 20 are respectively locked to the corresponding positioning and locking mechanism 121. The mesh hollow structure 21 covers the item 30, and the bottom of the mesh hollow structure 21 is arranged to mimic the convex shape of the item 30.

[0011] In specific implementation, the mesh hollow structure 21 is obtained by processing a planar material. The surface of the planar material has a pre-set unfoldable mesh pattern 211, which allows the mesh hollow structure 21 to expand in three dimensions, form a deformable structure, and be used to cover and fix the item 30. The grid pattern 211 is specifically a hexagonal, fish-scale, or rhomboid pattern to ensure that the stretched structure has sufficient support strength and elastic recovery. The grid pattern 211 of the mesh hollow structure 21 can be arranged in density according to the weight and shape of the packaged items 30, and the hollow rate is usually controlled between 30% and 70%. The platform portion 10 and the mesh structure portion 20 are made of the same material, and the fact that both are made of a single material reduces the amount of material used. The platform portion 10 and the mesh structure portion 20 are both made of corrugated cardboard, composite paper, or plastic sheet.
