Description

packing box {PACKING BOX}

The present invention relates to a packaging box, and specifically, it is possible to safely insulate and cool contents that are likely to deteriorate or decay during the distribution process, such as agricultural products, aquatic products and livestock products, and collide between the corners of the box during automatic folding through a box machine. It relates to a box that can reduce the possibility and can be rapidly decomposed in the natural environment to reduce environmental pollution.

In general, packaging boxes manufactured to store or transport contents such as agricultural products, aquatic products, and livestock products that require thermal insulation and cooling are mostly made of various materials such as paper, corrugated cardboard, and Styrofoam.

When such a packaging box is made of Styrofoam, it is possible to protect the contents stored inside from external impact as well as waterproof, thermal insulation, and cooling effects.

However, since the molded box body is compression-molded to maintain a constant volume to contain the contents, there is a problem that a large amount of cost is required for storage and transportation.

On the other hand, packaging boxes made of paper and corrugated cardboard are easy to manufacture, and they are stored in an unfolded and stacked state. For this reason, the waterproofness is greatly reduced, and the thermal insulation and cooling effects do not reach the expected level, and at the same time there is a problem that the contents stored inside cannot be properly protected due to external impact. As a result, there is a risk that a defect may occur.

In addition, as the use of courier and delivery increases, the use of packaging boxes used to safely transport contents is also increasing. As a result, the amount of boxes that are used for courier and delivery and then discarded increases, resulting in serious environmental pollution. In general, it takes 2 to 5 months for papers to decompose naturally. However, in the case of corrugated cardboard, which is mainly used for packaging boxes, it is thicker than normal paper, so it takes more than three years to decompose naturally. Therefore, it is necessary to develop a packaging box that can safely protect the contents stored inside and reduce environmental pollution without colliding with both adjacent edges of the box when automatically folded by a box maker.

An object of the present invention is to safely insulate and cool contents that are likely to deteriorate or decay during the distribution process, such as agricultural products, marine products, and livestock products, and reduce the possibility of collision between the corners of the box during automatic folding through a box maker, and natural It is to provide a box that can rapidly decompose in the environment and reduce environmental pollution.

In order to achieve the above object, the present invention is an inner box in which a space is formed that can accommodate the contents therein when folded inward along the fold line formed on the corrugated cardboard; an outer box into which the inner box is inserted; and a water-repellent coating layer applied to the inner surface of the inner box or the outer box.

In the present invention, the corrugated cardboard is sequentially spaced apart from each other at regular intervals, the inner cardboard and the outer cardboard; Intermediate cardboard disposed between the inner and outer cardboard; A first corrugated core disposed between the inner cardboard and the middle cardboard; And it includes a second corrugated core disposed between the intermediate cardboard and the outer cardboard.

In the present invention, the water-repellent coating layer contains 2.0 to 30.0% by weight of paraffin wax, 2.0 to 30.0% by weight of petroleum hydrocarbon resin, 0.0 to 1.0% by weight of resin alcohol, and 68.0 to 96.0% by weight of H ₂ O.

In the present invention, the cardboard is rectangular or square, and the fold lines are crossed with each other to form the bottom surface of the inner box, first and second lines; It includes a third line extending from the intersection of the first and second lines to the edge of the cardboard.

In the present invention, an incision is formed in the corrugated cardboard along the third line from the edge of the corrugated cardboard.

In addition, in order to check the decomposition period in the natural environment, the conventional packaging box is set as a control, and 10 mL of water is dispensed once every 2 days while keeping the same as in the natural environment, and the results are checked every month.

The packaging box according to the present invention can enhance the effects of cold storage, heat preservation, waterproofing, and moisture-proofing through the double structure of the inner box and the outer box and a water-repellent coating agent. It can reduce the possibility of collision between the edges of the corrugated cardboard during the folding process.

In addition, in order to confirm the decomposition period in the natural environment, the conventional packaging box was set as a control group and 10 mL of water was dispensed once every 2 days while the same was stored in the natural environment. Although the packaging box was completely disassembled, the conventional packaging box was not completely disassembled. Therefore, the packaging box of the present invention has the advantage of reducing environmental pollution because it decomposes faster than the conventional packaging box in a natural environment.
