Description

Fabricated paper lunch basket for one time}

The present invention relates to an environment-friendly disposable paper lunch box, which has two cutouts on three sides of the bottom of the original paper, which facilitates assembly and forms a rug on one side of the plate to have a stable shape after assembly. The present invention relates to a prefabricated paper lunch box so that the contents of the box are not damaged by preventing the box from being crushed in the event of shock.

With the growing importance of the environment as a whole, the transition to environmentally friendly economic and social structures is emerging as a survival strategy that can no longer be delayed by 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 expected 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 the most because of low cost of raw materials, simple production and easy use.

While the styropol lunch box has advantages, when used and disposed of, the corrosion rate is low and environmental hormone substances such as dioxins are released.

Therefore, we have come up with a variety of eco-friendly paper lunch boxes that can be used easily without polluting the environment at home or abroad.

Paper material is environmentally friendly, but very weak to moisture, so it is used for food containers with polyethylene coating on one or both sides.

The biggest reason to use paper or pulp mold container is that it is recommended for use in terms of practicality and price but it is environmentally friendly than styropol container.

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

Korea Patent Office Registered Utility Model Registration No. 20-0248675 The prefabricated paper lunch box container is introduced. The above technique folds along the bending line and inserts the joining protrusion into the joining groove. It is formed to have a small amount of warpage to the external impact and provides a cut disk, so it has the advantage of easy delivery and low volume.

However, the above technique involves the problem described below.

first. Due to the characteristics of the assembly type of the above technology, if the coating treatment is applied to the end face, the uncoated part is applied to the inner side part or the bottom part, so that it is applied to the synthetic resin container due to the moisture absorption.

second. Printing also needs to be printed on the inner bottom in order to harmonize with the printing area on the double side of the outside that is folded into the inner fitting groove when only the external cross section is used.

third. The side part is doubled, but the bottom part is doubled, and there is a gap between the cut grooves.

fourth. It is easy to be pulled out by being supported by being inserted into the defect protrusion and the engaging groove, and the side part which is supported on the inside in this layer is easy to be opened outside the aura.

fifth. Multiple cut grooves in the bent portion of the bottom and side of the inner layer are easily rotted by bacteria from the outside, or food in the container may dry out.

The present invention devised to solve the problems as described above is an object of providing a prefabricated paper lunch box that can meet the rigidity, convenience while single-side coating and single-sided printing.

Three incisions are placed at the bottom of the original cardboard to facilitate assembly and form a rug on one side of the plate to ensure a stable shape after assembly, thus preventing the box from being crushed under external impacts. It is related with the prefabricated paper lunch box so as not to be damaged.
