Description

Technical Field

[0001] This utility model relates to the field of packaging container technology, and in particular to a glue-free, quick-folding, glue-free octagonal snap-lock handle fruit box. Background Technology

[0002] With the rapid development of e-commerce and logistics, higher demands are being placed on the functionality, environmental friendliness, and economy of product packaging. Fruits, fresh produce, and gifts require sturdy yet portable packaging. Currently, most common paper fruit boxes on the market have the following drawbacks: Reliance on adhesive bonding: Extensive use of adhesive for securing the box bottom, sides, and handles. This not only generates pollution during production, contradicting green packaging trends, but also poses a food safety risk as the adhesive may contaminate the contents. Furthermore, the adhesive application process increases production costs and reduces production efficiency.

[0003] The assembly process is complex: For packaging boxes that require end-users to assemble themselves, the folding and locking steps are often cumbersome, making it difficult for non-professionals to complete the assembly quickly and correctly, resulting in a poor user experience. Some packaging boxes even require auxiliary tools, which is extremely inconvenient.

[0004] High transportation and warehousing costs: The volume of the empty packaging boxes after molding is fixed and cannot be effectively compressed. They occupy a lot of unnecessary space in the logistics chain from the manufacturer to the user, resulting in high transportation and warehousing costs.

[0005] Insufficient structural stability: Many packaging boxes have simple bottom and side wall structures with limited load-bearing capacity and compressive strength. They are prone to deformation and collapse during stacking, transportation, or handling, resulting in damage to the contents.

[0006] Difficult to recycle: Due to the use of glue or the presence of other non-paper materials, the dismantling and sorting recycling process is complicated, which is not conducive to the recycling of resources.

[0007] Therefore, there is an urgent need in this field for a packaging box solution that can completely eliminate the need for glue, has excellent folding convenience, can be fully flattened to save space when unloaded, and has a robust and reliable structure. Utility Model Content

[0008] The technical problem to be solved by this utility model is to provide a glue-free octagonal snap-lock handle fruit box that achieves environmental protection, quick assembly, durability and space saving in transportation by means of an integrally molded glue-free snap-lock and octagonal folding support structure.

[0009] To solve the above-mentioned technical problems, the technical solution of this utility model is: a glue-free octagonal snap-lock handle fruit box, including a box body, the box body including a bottom plate, side wall units, and a lid unit. The bottom plate is arranged horizontally, and the side wall units surround the outer perimeter of the bottom plate and can be bent vertically upward relative to the bottom plate.

The left rear side, right rear side, right front side, and left front side of the base plate are all connected to an octagonal folding support structure. The four octagonal folding support structures are respectively connected to the inner sides of the left and right ends of the first side wall unit and the second side wall unit. The octagonal folding support structure includes two right-angled triangular corner plates with the same structure. The length of the hypotenuse of the right-angled triangular corner plate is equal to the length of the corresponding side side of the base plate. The two right-angled triangular corner plates are mirror symmetrical and their vertices are set opposite each other. They fold inward relative to the base plate and cooperate with the locking structure so that the first side wall unit and the second side wall unit are folded up and surround the outer perimeter of the base plate, so that the cross-section of the box is octagonal.

[0011] Preferably, the first sidewall unit includes a first side plate, a second side plate, and a third side plate, all rectangular and of equal height, connected sequentially from left to right. The first and third side plates have identical structures and their lengths match the side edges of the base plate.

[0015] Preferably, the rear ends of the first and third side panels, and the front ends of the fourth and sixth side panels are each provided with a first auxiliary folding plate. The first auxiliary folding plate is used to guide and constrain the corresponding latch structure to bend at the correct angle, so as to achieve mutual self-locking or separation. The front and rear sides of the slot structure of the seventh and eighth side panels are provided with second auxiliary folding plates. The second auxiliary folding plates are used to guide the insert plate to stand vertically relative to the seventh and eighth side panels, ensuring that the slot is in the correct position to receive the flip cover support tongue, and enhancing the firmness of the connection between the insert plate and the seventh and eighth side panels. When the first cover plate and the second cover plate are bent inward to close, the first auxiliary folding plate and the second auxiliary folding plate cooperate with each other to form a continuous support structure on the inner side of the upper part of the box body, which is used to enhance the structural strength of the overall box body and the sealing of the lid.

[0016] Preferably, the front-to-back width of the first side plate and the left-to-right width of the seventh side plate are equal, both being 75.0mm to 85.0mm; the left-to-right length and front-to-back width of the bottom plate are equal, both being 290.0mm to 310.0mm; the left-to-right length of the first handle is equal to the left-to-right length of the bottom plate; and the front-to-back width of the first handle is 75.0mm to 85.0mm.

[0017] Preferably, the box body is integrally die-cut from a single piece of cardboard, and the bottom plate, side wall units, and lid units are all connected by pre-pressed crease lines.

[0018] The beneficial effects of this utility model are: Firstly, this utility model completely avoids the use of glue through its interlocking buckle structure and pre-compression crease design. The entire packaging box is made of a single material of cardboard, which is non-toxic and harmless. This not only makes the production process more environmentally friendly, but also completely eliminates the potential contamination of food by glue, ensuring safety and hygiene.

[0019] Secondly, this utility model, through the pre-designed locking structure at the bottom of the box and the flap support tongue and slot of the cover, allows users to quickly and securely assemble the entire box in tens of seconds through simple folding and plugging actions without any tools or professional knowledge, greatly improving the ease of use.

[0020] Thirdly, this utility model adopts an octagonal three-dimensional structure. The octagonal box body is formed by the side wall units and the inwardly folded right-angled triangular corner plates. This structure has excellent pressure resistance and impact resistance, and can effectively protect the contents from squeezing and collision during transportation. In addition, the interlocking of the bottom latches and the locking of the hook-shaped tongue on the cover with the slot together form a stable and solid three-dimensional space with strong load-bearing capacity and is not easy to fall apart.

[0021] Fourth, the transportation and storage costs of this utility model are extremely low. In the empty box state, it can be completely flattened into a single piece of cardboard for stacking and packaging, which greatly reduces logistics and storage costs. The production process only requires die-cutting, creasing, and waste removal. The process is simple and suitable for high-speed automated production, resulting in high production efficiency and reduced manufacturing costs. Since no foreign objects such as glue or nails are used, and it is made of a single paper material, it can be easily disassembled and flattened after use, making it convenient for users to discard and for recycling systems to handle, which is in line with the concept of circular economy.
