{A pakaging paper box for frozen food}

The present invention relates to a packaging paper box for substitute for styrofoam for packaging frozen or refrigerated foods, and in particular, when the four corner portion connecting part is formed at an angle of inclination of 45 degrees and overlaps to form a double folding wall, the connection gap of the box is generated. The present invention relates to a paper box for frozen food packaging that effectively blocks outflow of water even if water is generated during transportation from the packaged frozen food.

Generally, a packaging box used for freshly transporting frozen and refrigerated foods such as meat, dried fish, or vegetables is applicable to a variety of materials and forms, but is typically a packaging box made of styrofoam or synthetic resin and a paper box. Can be mentioned.

Among them, a packaging box made of styrofoam or synthetic resin material has a main body which is formed by pressing or injection molding in the form of a box in which the bottom surface and four wall surfaces are integrally formed with the upper surface open, and to protect the goods contained therefrom from the outside. It is made of a cover body laminated to cover the open upper surface of the main body.

However, in the case of a packaging box molded body made of synthetic resin material, the manufacturing cost is high and it can be used repeatedly a certain number of times, but it is difficult to recycle when damaged or contaminated. Therefore, a substantial amount of the sieve, which is virtually impossible to collect for recycling, is processed through incineration, and incineration generates a large amount of harmful gas, which causes problems of environmental pollution. Not only is it a significant problem that greatly contaminates the soil due to harmful environmental hormones generated during decomposition, but such box moldings are bulky and require relatively large space for transportation and storage. It has been a significant factor in increasing operating costs, resulting in an increase in logistics and management costs.

On the other hand, boxes made of styrofoam are mainly used for packaging and transporting aquatic marine products such as fish and shellfish, and have a predetermined heat insulation effect and are widely used for preservation of refrigerated or frozen foods. Therefore, in addition to the problem of vulnerable durability, which is easily damaged even when a small impact from the outside such as bumps or droppings between the boxes is applied, the amount of waste that is thrown away after being used for one-time use is enormous. It is a serious social problem.

On the other hand, the packaging box is made of paper, the bottom plate, the left and right side wall plate extending from the bottom plate, the front and rear side wall plate which is connected to the left and right side wall plate in a state extending from the bottom plate to form a peripheral wall, And a cover plate formed to cover the upper portion as a separate structure extending or separated from any one of the left and right side wall plates or the front and rear side wall plates.

Although the latter paper box is relatively easy to recycle and has many advantages in terms of environmental protection, the conventional paper box is assembled by attaching each of the left and right side wall plates and the front and rear side wall plates with an adhesive to each other, or the wall surface. In this process, a plurality of fitting grooves are cut in the connecting part such as the foldable position and the fitting protrusion formed by protruding integrally along the distal end of the wall plate, thereby allowing a large number of assembly gaps and spaces in the connecting part. This made it impossible to store or transport the contents contained in the box in a waterproof and warm state.

Moreover, since such a paper box is formed by folding a relatively thin sheet of paper, the paper box is easily broken when subjected to a pressing load from the top, thus making it difficult to safely store the contents. It was used in a limited way for temporarily transporting food.

The present invention is recyclable and does not generate harmful pollution when disposed of, a box for packing meat containing meat such as pork, beef, ribs, and frozen or refrigerated food packaging and transport boxes such as aquatic products containing fish or shellfish, etc. In addition, the main purpose is to provide a paper box for frozen food packaging that can be used for a variety of purposes, such as agricultural products, such as vegetables that must be kept fresh and preserved without being pressed or damaged during transportation.

In other words, the present invention is to provide a prefabricated packaging paper box that can be easily recycled, can be easily assembled, and is inexpensive to manufacture.

Another object of the present invention is to provide a prefabricated packaging paper box excellent in durability that can safely store the contents without being easily damaged against the pressing load from the top even if transported or stored by stacking a plurality of boxes containing the goods. I will.

Another object of the present invention is used as a box substitute for styrofoam for packaging frozen or refrigerated foods, and since the four edge connection parts have a double folding wing when assembling, the connection gap of the box does not occur, so the packaging Even if water is generated during transportation from frozen food, it is to provide a paper box for frozen food packaging excellent waterproofing effectively blocking outflow to the outside.

Another object of the present invention is to form an air layer on the wall surface made of corrugated cardboard, which is excellent in heat retention, and after sealing the assembled box body with a cover body and wrapping the lower end of the cover body with a tape formed on the front and rear wall surfaces of the box body. The purpose of the present invention is to provide a prefabricated packaging paper box having excellent thermal insulation which is covered by a plate fitting groove to block the inflow of external air.

The present invention, which achieves the above object, is made of a piece of paper having a certain thickness, is stored in a developed state by a combination of incision and fold line, and in a packaging paper box to form an article receiving space by simply assembling in use, A bottom plate disposed in a square shape in the center; Front, rear, left and right sidewall plates each having an outer edge of the bottom plate as first and second fold lines and extending outwardly therewith; When both ends of the front and rear and left and right side wall plate as the third and fourth fold line is extended to the outside of the boundary and the split fold line is formed between the third and fourth fold line to fold the front and rear and left and right side wall plate A corner overlapping plate that constitutes a double folding wall inwardly; On the outside of the left and right side wall plate to form a wing plate is connected to the extension cover plate and both ends again, while forming a wing plate fitting groove which is cut in the transverse direction on both sides of the front and rear side wall plate to be spaced apart from the bottom, The wing plate of the extension cover plate is characterized in that configured to form a box by being fitted into the wing plate fitting groove of the front and rear side wall plate.

In the present invention, preferably, the paper is corrugated cardboard, and an inner surface thereof is characterized in that a waterproof coating layer is formed.

In the present invention, it is preferable that an alignment protrusion extends on one surface of the front and rear sidewall plates.

The present invention is also formed in the left and right locking grooves, the wing plate is preferably configured to be the same height as the front and rear side wall plate forming the wing plate fitting groove.

At this time, the front and rear and left and right side wall plate height of the cover body is configured to maintain the height from the top of the front and rear side wall plate of the box extending from the bottom plate to the wing plate fitting groove, the wing plate fitting groove by the cover body. It is preferable that the end portions of the front and rear side wall plates which are covered or extended from the cover plate coincide with the wing plate fitting grooves.

The present invention configured as described above is particularly useful as a box substitute for styrofoam for packaging frozen or refrigerated foods, and since the four corner portion connecting parts have double folding walls, packaging gaps do not occur due to the packaging. Even if water is generated during transportation from frozen foods, it is possible to effectively block the flow out.

In the present invention, the double folding wall of the corner portion stably supports the upper load when stacking boxes, and further increases its supporting force by the wing plate fitted into the wing plate insertion groove formed on the front and rear side wall plates. When the paper box of the present invention is formed by corrugated paper to form an air layer on the wall, it is excellent in heat retention, and the assembled box is sealed with a cover, and then the lower end of the cover is wrapped with tape. The wing plate fitting grooves formed on the front and rear walls of the box are covered to block the inflow of external air, thereby providing a complete sealing effect.
