FIG. 2 is a view showing a state where a reinforcing portion of a paper box having a reinforcing portion, which is easy to cut and load,
3 is a view showing an embodiment of a reinforcement according to the present invention,
4 is a view showing another embodiment of a paper box having a reinforcing part which facilitates saving and loading of raw materials according to the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings.

1 to 4, the present invention mainly includes a box body 100, a reinforcing portion 200, and a reinforcing material 300.

At this time, the box body 100 has the corrugated cardboard 10 in which the corrugated corrugated paper 12 is formed between the front and back liner papers 11 by folding the bottom part 110, the wall part 120, And a lid part 130, and a fitting groove 121 is formed at the upper end of the four corners of the wall part.

This corrugated cardboard is most preferable for producing a paper box, and is advantageous in that it is lighter in weight than conventional wood, metal or synthetic resin material, has excellent recyclability, is environmentally friendly, and relatively low in raw material cost.

2, the reinforcing part 200 is formed with a clip part 210 to be coupled to the fitting groove 121 of the box body 100, and integrally formed with the clip part , And the reinforcing pillars 220 are formed to support the load during box stacking.

At this time, the reinforcement column 220 is preferably made of the same corrugated cardboard as the box body, and may be formed of a synthetic resin material or metal when a high supporting force is required depending on the environment in which the box is loaded or the cargo in the box.

3, the reinforcing column 220 includes an inner column 221 configured to support an inner side of a corner of the box body 100, and an outer column 222 supporting an outer side of the corner.

In other words, the reinforcing column may be made of synthetic resin or metal to improve the bearing capacity of the reinforcing column. However, in this case, since the cost of the raw material is increased, the reinforcing column is formed of a corrugated cardboard material, and both the inside and outside of the corner portion of the box body can be supported So as to have a higher supporting force with respect to the vertical load.

4, the box body 100 includes a plurality of auxiliary fitting grooves 120 spaced apart from each other by a predetermined distance along a wall 120-1 of the wall portion 120, A plurality of reinforcing pillars 220-1 are provided to be coupled to the auxiliary fitting grooves 122 and are formed in a shape of a letter " A reinforcement portion 200-1 composed of a portion 210-1 is formed.

The reinforcing portion 200-1 can prevent the box portion from being distorted or deformed by the clip portion 210-1 covering the entire upper end portion of the wall portion.

Further, even when the box body 100 is sealed (closed) by the lid part 130, the reinforcing part can be easily coupled to the box body 100 from the outside through the fitting groove.

Meanwhile, the box body 100 is coated with a reinforcing material 300 on the surface of the wall part 120 to enhance a supporting force against a vertical load.

That is, by coating the stiffener 300 to strengthen the supporting force against the wall part 120, which is substantially burdened with the load when the box is loaded, it is possible to reduce the cost by making the corrugated cardboard thinner than the conventional box The durability against warpage and distortion can be kept the same.

In other words, it is preferable that the stiffener 300 is applied on the surface of the wall part 120 using a spraying method or an extrusion roller.

The reinforcing material 300 is applied or filled between the liner paper 11 and the corrugated paperboard 12 of the wall part 120.

In addition, the reinforcing member 300 includes at least one reinforcing member 310 selected from a fiber material, a stone powder, and a fragrant powder.

The reinforcing material 300 is formed in a liquid or paste form, and the fibrous material is preferably formed of a fiber having excellent strength such as carbon fiber, glass fiber, aramid fiber, or silicon fiber.

Accordingly, the present invention is characterized in that a reinforcing pillar is formed at the corner of a paper box so that a paper box stacked in various layers in various packing and loading processes can be safely stacked without being crushed or damaged by weight, By strengthening the bearing capacity and coating the reinforcing material on the wall of the box, the thickness of the corrugated cardboard is made thinner than that of the conventional paper box, while the raw material is reduced, while the supporting force against the vertical load of the box can be maintained. It is possible to have an effect.

Further, it is possible to easily install the reinforcing column even when the box is sealed, and in the case of a relatively heavy weight, it is possible to provide an auxiliary fitting groove to more firmly support the wall of the box, It is possible to provide a box having improved durability.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims. Of course, such modifications are within the scope of the claims.
