Description

High strength packing carton

Technical Field

The utility model relates to a carton for packing, concretely relates to high strength packing carton.

Background

The carton is the most widely used packing product, and the carton is because the low price, low in production cost can cyclic utilization and receives people's liking. Although the carton is convenient to use, the carton is made of paper, so that the compression strength of the carton is weak. To ensure better compression resistance of the carton, the quality and production process of the carton paperboard need to be improved, which needs to improve the content of high-quality fibers in the carton paperboard, wherein the high-quality fibers are derived from wood with better quality, and the wood with better wood quality is used for manufacturing higher-grade furniture.

The existing paper box paperboard generally adopts waste paper and other fibers which are used for the second time, the mechanical property of the fibers is reduced after the fibers are used for the first time, the bearing capacity and the strength of the paper box paperboard made of the fibers are poor, and the service life is short. Meanwhile, the carton is easy to damp and deform, particularly, the corners of the carton are easy to wear and damage in the packaging, unloading and moving processes. And the waterproof and moistureproof performance of the carton is poor, which affects the protection effect of the carton on articles in the carton.

SUMMERY OF THE UTILITY MODEL

To foretell not enough, the utility model provides a big, the intensity of bearing capacity is high, waterproof nature is good, not fragile packing carton.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a high strength packing carton, includes the box that forms by the integrative composite pressing of multilayer cardboard, the box includes four side boards of enclosing into four walls of carton and connects respectively in the both ends of side board and can turn over the case lid of folding, all is provided with the strengthening rib of a set of mobile dismouting at the surface of each side board, constitutes the cardboard of box is from interior to exterior for honeycomb paper layer, crushing resistant layer, corrugated paper layer, waterproof layer in proper order, and just at the equal vertical stay of installing in four inside corners of box.

In the above solution, in order to improve the supporting and reinforcing effects of the reinforcing rib, the reinforcing rib is preferably two nylon ropes or elastic ropes which are connected to opposite corners of the side panel in a cross manner.

In the above scheme, in order to prevent the situation that the carton is easy to absorb water and damp when the carton is arranged on a damp ground, the upper end and the lower end of each side panel are respectively bonded with a waterproof adhesive tape.

In the above scheme, in order to improve the strength of the wall body of the carton, the compression-resistant layer can be a copper plate paper layer coated with nano calcium carbonate on the surface.

In the scheme, the waterproof layer can be a high-density polyethylene film, and the thickness of the waterproof layer is 0.1-0.3 mm.

The utility model has the advantages that:

1. the utility model discloses the strengthening rib of cross arrangement can improve the horizontal bearing capacity of box on four side boards and can improve the vertical bearing capacity of box at the support bar of four inside corner installations of box, and the box is formed by the compound suppression of multilayer cardboard, and the resistance to compression layer of establishing has further improved the intensity of box, compares with prior art: the packaging carton has the characteristics of large bearing capacity, high strength and strong pressure resistance;

2. the outermost waterproof layer of the box body is a waterproof layer, waterproof adhesive tapes are bonded at two ends of each side panel, the waterproof and moisture-proof properties of the box body are improved, the honeycomb paper layer is arranged to improve the shock resistance of the carton, and the packaging carton has the advantages of being simple in structure and high in practicability.

Drawings

Fig. 1 is a schematic structural view of the high-strength packing carton.

Fig. 2 is a schematic sectional view of a paperboard constituting a box body.

The reference numbers in the figures are: 1. a box body; 2. a supporting strip; 3. reinforcing ribs; 4. waterproof rubberizing; 5. a waterproof layer; 6. a corrugated paper layer; 7. a pressure resistant layer; 8. a honeycomb paper layer.

Detailed Description

The invention is further explained below with reference to the drawings and the embodiments without limiting the invention.

As shown in figure 1, a high strength packing carton comprises a carton body 1 formed by integrally laminating and pressing a plurality of layers of paperboards, wherein the carton body 1 comprises four side panels enclosing four walls of the carton and a box cover which is respectively connected with two ends of the side panels and can be turned and folded, and a group of reinforcing ribs 3 which can be movably disassembled and assembled are arranged on the outer surface of each side panel. The reinforcing ribs 3 are two nylon ropes or elastic ropes which are mutually crossed and connected to the opposite angles of the side panels. A waterproof adhesive tape 4 is bonded at the upper end and the lower end of each side panel, and the specific structure of the waterproof adhesive tape 4 can be a transparent adhesive tape.

All vertically install a support bar 2 at four inside corners of box 1, the setting of support bar 2 can improve the vertical bearing capacity of carton. The supporting bars 2 can be hard plastic bars or wood bars with smooth surfaces, and can be vertically arranged on corners inside the box body 1 in an adhesion mode or a clamping mode.

As shown in fig. 2, the paper board constituting the box body 1 comprises a honeycomb paper layer 8, a compression resistant layer 7, a corrugated paper layer 6 and a waterproof layer 5 in sequence from inside to outside. Wherein,

the anti-compression layer 7 is a copper plate paper layer coated with nano calcium carbonate on the surface, and can be made of other high-strength materials with anti-compression effect. The waterproof layer 5 is a high-density polyethylene film, and the thickness of the waterproof layer is 0.1-0.3 mm.

The above description is only for the purpose of illustrating the embodiments of the present invention and should not be construed as limiting the present invention, and any modifications, equivalent replacements, improvements, etc. made by the technical personnel in the field within the spirit and principle of the present invention should be included in the protection scope of the present invention.
