According to the shockproof corrugated board carton, the bearing capacity of the side wall of the carton can be effectively enhanced, the shockproof, waterproof and damp-roof capacities are obviously improved, and the printing of the surface carton is not influenced.

Description

A shockproof corrugated cardboard box

technical field

The utility model relates to the technical field of cardboard cartons, in particular to a shockproof corrugated cardboard box used for transporting expensive products or easily broken products.

Background technique

The corrugated box of the prior art includes a box cover, a box body and a box bottom. The box cover and the box bottom are both composed of four flaps. Multiple packaging is not conducive to the packaging of products, which is time-consuming and labor-intensive, especially when stacked in multiple layers, the side of the corrugated box is under greater pressure, especially the box at the bottom, which is easily deformed and crushed, causing damage to the items in the box , The vibration during transportation is also very easy to damage the fragile items in the box.

At the same time, the existing carton production cannot effectively protect the inner wall of the package from being soaked, and cannot ensure the erosion of the product under high temperature, high humidity, high salinity and other environments. In order to be waterproof and moisture-proof, the existing technology has the outer layer dipped in wax and the outer layer coated with waterproofing agent, but the wax layer and waterproofing agent coated on the outer layer are easy to fall off and damaged, and cannot be guaranteed for a long time, and the wax layer and waterproofing agent layer Generally, they are relatively smooth, which is not convenient for printing on the surface of the cabinet.

Contents of the invention

The purpose of the present invention is to provide a corrugated box that can effectively prevent shock and deformation, increase the bearing capacity of the side wall, and is not affected by many external factors.

The corrugated cardboard box described in the utility model includes a box body, a box cover, and a box bottom. The box body, box cover, and box bottom plate are composed of face paper, an intermediate layer, and a bottom paper. It is characterized in that: the intermediate layer is composed of surface pits, It consists of a core paper and a bottom pit, and a foam material layer is also arranged on the bottom paper.

Furthermore, the thickness of the foam material layer is 5mm.

Furthermore, in order to enhance the high compressive capacity of the corrugated paper and increase the bonded area between the core paper and the surface and bottom pits, the cross-section of the core paper is set in a continuous U-shape or V-shape or UV combined shape.

Furthermore, the intermediate layer is one or more layers.

The middle layer of the carton plate of the utility model is composed of surface pits, core paper, and bottom pits. The bottom paper is provided with a foam material layer, which can effectively enhance the bearing capacity of the side walls of the box body, and the shockproof, waterproof and moisture-proof capabilities are significantly improved. Affect surface case printing.

Detailed ways

The utility model is further described below in conjunction with the accompanying drawings of the description.

As shown in Figures 1 and 2, the corrugated cardboard box described in the utility model is composed of a box surface, a box body, and a box bottom. 4. The base paper 5 and the foam material layer 6 are bonded in sequence. Wherein, the surface paper 1 is the outer surface of the box, the surface paper 1 is pasted on the face pit 2, the cross-sectional protrusion of the core paper 3 is used to bond with the face pit 2 and the bottom pit 4, and the other part of the bottom pit 4 While bonding the bottom paper 5, the outer surface of the bottom paper 5 is further pasted with a reinforcement layer 6, and the foam material layer 6 is the inner surface of the casing.

Among them, the middle layer composed of surface pit 2, core paper 3, and bottom pit 4 is a buffer layer. As shown in Figure 3, the cross section of core paper 3 is set in a continuous U shape, which can effectively increase the thickness of the surface pit 2 or bottom pit 4. Adhesive area, enhanced firmness, as shown in Figure 4, the cross-section of the core paper 3 is set in a continuous V shape, which can effectively enhance the compression resistance, according to specific needs, as shown in Figure 5, the core paper 3 can also choose continuous UV cross shape settings. The buffer layer can be set in multiple layers, and the buffer layer can be set in multiple layers. The multi-layer is a layer of core paper 3 with a U-shaped cross-section, a layer of core paper 3 with a V-shaped cross-section, and a layer of core paper 3 with a horizontal cross-section. The cross-section is set to UV type, and a combination of two or three is performed according to specific needs.

The foam material layer 6 is made of 5mm foam material.

The utility model has been described in detail above according to the preferred embodiment, but it should be understood that the utility model is not limited to the specific embodiment, and those skilled in the art make any changes and changes according to the spirit of the claims of the utility model. All changes should fall within the protection scope of the present utility model.
