Description

High-strength corrugated carton

Technical Field

The utility model belongs to the technical field of the packing box technique and specifically relates to a high strength corrugated box.

Background

Corrugated paper is a widely used carton making material, and has the advantages of high structural strength and low cost. Corrugated board means that a middle layer extending in a wave shape is arranged between two outer covering surfaces, so that compared with common hard board, the corrugated board has better structural strength.

The existing cartons all comprise a box body consisting of a few four walls and a bottom surface and a box cover. The four walls of the box body are respectively composed of four corrugated boards, and the edges of the four corrugated boards are folded together to form a bottom surface. The cover can be a separate cover or can be the same structure as the bottom (i.e. the edges of four corrugated boards are folded together to form the top). The closed angle of the bottom of the existing corrugated case in the transportation process is easy to impact, so that the corrugated case is deformed and damaged, the damage of the corrugated case is easy to cause in-process use of the corrugated case, the service life of the corrugated case is further shortened, and the use cost is increased.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following description will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Fig. 1 is a schematic structural diagram of a high-strength corrugated carton according to an embodiment of the present invention. Fig. 2 is a schematic structural view of a corrugated cardboard sheet of a high-strength corrugated box according to fig. 1. Fig. 3 is a schematic view showing a structure of a rigid splint for corrugated cardboard of a high-strength corrugated container according to fig. 1. As shown in fig. 1 to 3, the present invention provides a high strength corrugated cardboard box, which may generally include a box body 1 having a hexahedral shape. The box 1 comprises six faces, two of which are oppositely arranged as a first panel 12 and a second panel 13, and the other four faces are four walls 11 of the box 1. The first panel 12 and the second panel 13 may be any one of the group of upper and lower surfaces, left and right sides, or front and rear surfaces. The first panel 12 and the second panel 13 are rigid splints. The hard plywood may be a wood board, a plastic board, an acrylic board, a metal board, or the like. The hardness and the structural strength of the hard splint are both greater than those of the corrugated board. The four walls 11 of the box body 1 are formed by bending the whole corrugated paper board 2. The edge of the corrugated board 2 is fixedly connected with the hard clamping plate to form a box body. As shown in fig. 2 and 6, the corrugation direction 23 of the interior of the corrugated cardboard 2 is perpendicular to the bending line 22 of the corrugated cardboard 2, so that the corrugated cardboard 2 has better structural strength when being fixedly connected with the rigid splint after being bent. As shown in fig. 5, a plurality of reinforcing members 3 are provided between the first panel 12 and the second panel 13 inside the cabinet 1. The two ends of the reinforcing member 3 are respectively fixed to the inner side surfaces of the end corners corresponding to the first panel 12 and the second panel 13 by bonding with an adhesive. The number of stiffeners 3 may be 2 or four. When the number of the reinforcing members 3 is 2, two reinforcing members 3 are respectively provided at two end corners of the inner lower surface of the case 1. When the number of the reinforcing members 3 is 4, 4 reinforcing members 3 are respectively provided at both end corners of the inner lower surface and both end corners of the upper surface of the case 1. Optionally, the reinforcement 3 is made of EVA ("ethylene vinyl acetate" and its rubber-plastic foam) material or high-density sponge (sponge with a weight of more than 25 kg per cubic meter of sponge). The reinforcing member can further reinforce the structural strength of the carton body 1 at the 8 impact corners, so that the carton body 1 has sufficient structural strength and long service life. The reinforcing part 3 can also be used for protecting articles placed in the box body 1, and plays a role in buffering and preventing collision.

Further, the corrugated board 2 is fixedly connected with the hard splint by an adhesive or a gun nail. The corrugated board 2 is formed by bending the whole rectangular corrugated board. The rectangular whole corrugated board can improve the utilization rate of raw materials, and the processing efficiency is high in cost and low in cost. The production efficiency can be improved by fixedly connecting the adhesive or the gun nail. Alternatively, as shown in fig. 3 and 4, the peripheral edges of the first panel 12 and the second panel 13 are provided with a flange 4 facing the inside of the case 1. The corrugated board 2 is fixedly connected with the flanging 4 through adhesives or gun nails. The cuffs 4 may be continuous or spaced apart. The turned-up edge 4 can increase the contact area between the corrugated cardboard 2 and the first panel 12 and the second panel 13, which helps to prolong the service life of the corrugated carton.

The corrugated cardboard 2 also comprises a bent cover edge 21. The cover edge 21 is detachably connected with the corrugated board 2 after being bent through an adhesive, a lock catch, a magnet, a magic tape and the like. The cover edge 21 is turned to open or close the box body 1. Optionally, the cover edge 21 is connected by the lock catch 5, which has the advantages of beautiful appearance, simplicity and generosity.

The case 1 is also provided with a handle 14 for easy access. The handle 14 is fixedly arranged on the outer surface of the first panel 12 and/or the second panel 13. Optionally, the handle 14 is not a riveted, snap-fit, strap-like structure.

The utility model provides a pair of high strength corrugated box, its stereoplasm splint can adopt abandonment leftover bits to make, can material saving, do benefit to the environmental protection. And the four walls of the box body are formed by bending the whole corrugated board, the rectangular whole corrugated board can improve the utilization rate of raw materials, and the processing efficiency is high and low.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
