Fabricated paper lunch basket for one time}

The present invention relates to an environment-friendly disposable paper lunch box, which has a cutout on a group day at the bottom bent portion of the original paper, and has a fitting groove in the partition wall part to facilitate assembling and to form a rug on the inside of the bottom part to form a stable shape after assembly. The present invention relates to a prefabricated paper lunch box, which does not damage the contents of the box by preventing the box from being crushed even when the external impact is caused.

With the growing importance of the environment around the world, the transition to environmentally friendly economic and social structures is emerging as a survival strategy that can no longer be delayed due to the Convention on Climate Change and strengthening trade pressures for environmental protection in each country.

In Korea, as in developed countries, the producer-recycling recycling system, which requires producers to recycle, is scheduled to be implemented.

In particular, the reduction of one-time goods and packaging materials, which is one of the original reduction policies of wastes, is the highest policy tool in the priority of waste management policies, and is the first priority in consideration of the situation in Korea where the amount of waste load per land area is large. Efforts are being made to replace disposable products that are inevitably used with environmentally friendly products.

Disposable lunch box of the above-mentioned disposable products is not only a variety of types, but also a lot of types are produced.

A typical disposable lunch box is Styropol, which is mainly made of expanded polystyrene.

The styropole lunch box has been used most commonly as a general container because of low cost of raw materials, simple production and easy use.

In high-quality and customized containers such as Japanese sushi, it is made of low-foam polystyrene and used.

The fabrication process is to make a wide plate in the form of a sheet, and to laminate a polyethylene or polyfluoropropylene film, usually printed with a wooden pattern, on one side of a disc of a certain standard, cut it to a desired standard, and cut it to the desired standard. And each side wall portion is manually glued to each cut portion with an adhesive to form a container.

According to such a manual manufacturing process, there are vulnerabilities in the production of various printing and various specifications, and the price is also very high.

In addition, when disposed of and disposed of after use, the corrosion rate is slow and environmental hormones such as dioxins are released.

Therefore, the inventors have developed an eco-friendly paper lunch box that can be used easily without contaminating the environment.

Paper materials are environmentally friendly, but very weak to moisture, and are used as food containers by treating polyethylene on one or both sides.

Environmentally-friendly paper containers are allowed to have polyethylene coating and laminating coating on one side, but when coated on both sides, they are not recognized as eco-friendly materials because they are defined as synthetic resin containers.
