Description

Technical Field

[0001] This utility model relates to the field of paper packaging technology, specifically to paper packaging for electronic products. Background Technology

[0002] Paper packaging for electronic products uses paper as its main material. It can be manufactured using pulp molding processes or by purchasing finished paper and combining it with die-cutting, folding, and gluing processes to create packaging containers. It is primarily used for the transportation and storage protection of electronic products. Functions include cushioning and shock absorption, pressure and impact resistance, moisture and stain protection, while also offering advantages such as lightweight, biodegradability, cost control, and environmental recyclability. It is widely used, especially in consumer electronics and precision instruments.

[0003] To provide good shock absorption for electronic products in paper packaging, traditional paper packaging often uses polystyrene foam as the support in the packaging box. However, polystyrene foam is non-degradable and difficult to recycle, which contradicts the environmentally friendly nature of paper packaging. The static electricity accumulation effect of foam may induce damage to electronic components. Summary of the Invention

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a paper packaging for electronic products, which uses paper packaging as its cushioning and support structure.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: A paper packaging for an electronic product includes a paper box body with an internal cavity. The paper box body has a top cover and a bottom surface. The side wall of the paper box body has continuous folded edges from the edge of the cavity into the cavity. Multiple continuous folded edges are connected sequentially to form a support frame with an incomplete annular cross-section. The support frame has a cavity in the middle and its outer periphery abuts against the side wall.

[0006] The continuous knot here can be cut and set as an integral part with the cardboard box body, which facilitates the processing structure.

[0007] It is necessary to explain that when a support frame is provided on the side of the top cover, the top cover can be made separately with an adhesive allowance and then glued to the outside of the cardboard box body.

[0008] As a preferred technical solution, one of the two adjacent side walls of the cardboard box body is provided with a slot, and the other side wall is provided with an insert that fits the slot.

[0009] As a preferred technical solution, the cross-section of the support frame is a U-shape with an opening on the side near the receiving cavity.

[0010] As a preferred technical solution, the slot is located inside the opening. The slot is embedded inside the opening, allowing the support frames on both the upper and lower sides of the insert to provide some support, making the adjacent support frame structure more stable and reducing the risk of separation.

[0011] As a preferred technical solution, a support piece is also provided on the inner side of the opening, and a limiting hole is formed on the surface of the support piece, and the contents are embedded in the limiting hole.

[0012] As a preferred technical solution, multiple cutting lines are arranged radially at the edge of the hole, and a flap is arranged between adjacent cutting lines.

[0013] As a preferred technical solution, the support piece is a horizontally arranged rectangular cylinder. The rectangular cylinder has limiting holes on both its top and bottom sides, and the flaps between the two limiting holes are symmetrical vertically. These symmetrical flaps are essentially formed by continuously cutting limiting holes into a long piece of cardboard. The long cardboard is then rolled to form the rectangular cylinder, providing support for the contents in the thickness direction. Compared to a single support piece, this provides more stable support, and since the rectangular cylinder has no vertical division, the flaps are not obviously exposed, thus providing a better visual effect.

[0014] As a preferred technical solution, one of the multiple sidewalls is provided with a connecting groove at the end located on the outside of the carton body, and the top cover is engaged with the connecting groove by a connecting piece and the fins provided at its end.

[0015] As a preferred technical solution, a pulp molding structure or a cardboard folding structure is used. Specifically, when using a pulp molding structure, if the structure is relatively complex, an integrally connected paper sheet can be produced first, and then folded into shape. If the structure is simple, it can be molded into a semi-finished product, and then further processed to complete the assembly. Specifically, a mold with a flange is used to obtain grooves and continuous folds for the wet pulp blank. The flanges are then inserted into the grooves, the hot pressing is stopped, the mold is removed, and finally, the pulp is air-dried.

[0016] The advantages and beneficial effects of this utility model are as follows: The cardboard box body is assembled into an incomplete annular cross-section support frame through continuous folded edges extending inward from the side walls. Adjacent side walls adopt a slot and insert interlocking structure to achieve glue-free splicing. A rectangular cylindrical support piece is embedded in the inner side of the U-shaped opening of the support frame. Limiting holes with radial cutting lines are opened on both sides, and the edge of the holes is divided into foldable and adjustable flaps. The top cover is locked to the end of the box body side wall through a fin-connecting groove snap-fit ​​mechanism. The support frame, through the U-shaped opening design, disperses external pressure to the tangential direction of the side walls, providing good support performance for electronic products without the use of foam plastic, and providing a solution for all-paper structure packaging.

Detailed Implementation

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0019] Example 1 Please see Figures 1-2 This embodiment provides a paper packaging for an electronic product, including a paper box body 1 with an internal receiving cavity 2. The paper box body 1 is provided with a top cover 3 and a bottom surface 4. The side walls of the paper box body 1 are provided with continuous folded edges 5 from the edge of the receiving cavity 2 into the receiving cavity 2. Multiple continuous folded edges 5 are sequentially connected at their edges, forming a support frame with an incomplete annular cross-section. The support frame has a cavity 6 in the middle, and its outer periphery abuts against the side walls. The paper box body 1 is made of corrugated paper or honeycomb paper. One of the multiple side walls is provided with a connecting groove 15 at its outer end. The top cover 3 is engaged with the connecting groove 15 through a connecting piece 16 and a fin 17 at its end.

[0020] Example 2 Based on Embodiment 1, one of the two adjacent side walls of the cardboard box body 1 is provided with a slot 7, and the other side wall is provided with an insert 8 adapted to the slot 7.

[0021] Example 3 Based on Embodiment 2, the cross-section of the support frame is U-shaped with an opening 9 near the receiving cavity 2. The slot 7 is located inside the opening 9. A support piece 10 is also provided inside the opening 9, and a limiting hole 11 is formed on the surface of the support piece 10, with the contents embedded in the limiting hole 11.

[0022] Example 4 Based on embodiment 3, multiple cutting lines 12 are radially arranged at the edge of the limiting hole 11, and a flap 13 is arranged between adjacent cutting lines 12. The support piece 10 is a rectangular cylinder 14 arranged laterally, and the limiting hole 11 is provided on both the top and bottom sides of the rectangular cylinder 14. The flaps 13 between two limiting holes 11 are symmetrical vertically.

[0023] Example 5 The only difference from Example 4 is that the packaging box is formed by two-stage molding, forming the cardboard box body and the support frame one after the other, and then assembling the two into one piece.

[0024] The working principle of this utility model is as follows: the paper packaging of this utility model consists of a paper box body 1, a top cover 3, and a bottom surface 4 forming a main frame. Multiple continuous folded edges 5 extend inward from the edge of the receiving cavity 2 and interconnect to form a support frame with a U-shaped cross-section (opening towards the inside of the receiving cavity). The support frame has a cavity 6 in the middle, which abuts against the side wall of the paper box body on the outside, and a support piece 10 is embedded in the opening on the inside. The support piece is designed as a horizontal rectangular cylinder 14, with limiting holes 11 with radial cutting lines 12 on its surface. The edge of the hole is divided to form a foldable flap 13. Adjacent side walls are interlocked and reinforced by inserts 8 and slots 7. When an external impact force is applied, the support frame uses the U-shaped cross-section opening 9 to convert the pressure into a tangentially distributed transmission to the side walls. The flap 13 folds inward to adapt to the embedded contents according to the size of the contents. The inserts 8 lock the side walls by embedding into the slots 7. Achieving efficient cushioning without foam plastic: The support frame provides impact protection through stress dispersion, and the cavity 6 acts as a buffer space to absorb vibration energy; the folding action of the flap 13 ensures that the contents are stably locked into the limiting hole 11 to prevent displacement.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
