본 발명은 종이 도시락용기의 제조방법에 관한 것으로, 보다 상세하게는 단면 코팅에 의한 친환경적인 종이재질로서 일체의 성형에 의해 제조되어 습기나 외 부의 충격에도 용기의 형태를 그대로 유지함으로서 내용물의 손상을 방지할 수 있고, 밀폐성의 향상으로 내용물의 누출을 방지하여 위생적으로 포장되는 종이 도시락용기의 제조방법에 관한 것이다.The present invention relates to a manufacturing method of a paper lunch box, and more particularly, it is manufactured by integral molding as an eco-friendly paper material by a single-side coating to maintain the shape of the container intact to moisture or external impacts to prevent damage to the contents. The present invention relates to a manufacturing method of a paper lunch box, which can be prevented and prevents leakage of contents by improving the sealing property and is hygienically packed.

근래에 식품가공 기술의 발달로 인하여 다양하게 가공 처리되어 포장용기에 넣어져 일반 수요자들에게 위생적으로 공급되어 수요자는 별도의 처리 없이 바로 취식할 수 있는 가공처리 식품이 급속히 신장되고 있는 현실이다.Recently, due to the development of food processing technology, various processed foods are put into packaging containers and hygienically supplied to general consumers, and processed foods that can be eaten immediately by consumers without additional treatment are rapidly expanding.

위생적으로 가공 처리된 식품이 최종 일반 수요자에게 전달 될 수 있도록 하기 위하여 값이 싸면서도 가볍고 취급이 용이한 합성수지재의 포장용기를 사용하고 있다.In order to ensure that hygienically processed foods are delivered to end users, they are inexpensive, lightweight and easy to handle.

하지만 전세계적으로 환경의 중요성이 증대됨에 따라 친환경적인 경제, 사회구조로의 전환이 이루어지고 있어 불가피하게 사용되어지는 일회용품은 재활용 가능하게 제조됨과 동시에 환경친화적인 제품으로 대체화하려는 노력이 지속되어야 한다.However, as the importance of the environment is increasing all over the world, the transition to eco-friendly economy and social structure is taking place, and efforts to replace disposable products that are inevitably used with eco-friendly products must be continued. .

이에 따라 국내에서도 간편하게 사용되어 질 수 있는 친환경적인 종이용기를 다양하게 개발하고 있다.Accordingly, we are developing various eco-friendly paper containers that can be used easily in Korea.

일반적으로, 식품을 저장하는 일회용 도시락용기는 단면이 코팅된 친환경재질을 사용하고 있으나 공통적으로 조립식으로 되어 있어서 수작업을 하여 재단된 각 부분을 서로 연결하여 도시락용기의 모양을 형성하였다. 더욱 우수한 구조강도를 갖도록 하기 위하여 각 부분은 보조할 수 있는 부분을 구비하고 있으며, 이러한 부분에 의해 이겹으로 연결되어 내용물을 저장할 수 있도록 용기를 완성시키게 된 다.In general, a disposable lunch box for storing food uses an eco-friendly material coated with a cross-section, but in general, it is prefabricated to form the shape of a lunch box by connecting each cut portion by hand. In order to have a better structural strength, each part is provided with a subsidiary part, which is connected in two layers to complete the container to store the contents.

그러나, 종래의 용기는 조립식으로 되어 있어서 용기의 조립에 일정시간이 소요되어 대량생산에 따른 조립시간과 작업라인을 갖추어야 되고, 외부의 충격에 용기 형태를 유지하기가 힘들며, 습기에도 약하여 저장된 내용물이 손상될 수 있다.However, the conventional container is prefabricated, so it takes a certain time to assemble the container, so that the assembly time and the work line according to mass production are required. Can be damaged.

또한, 밀폐성이 좋지 않아 내용물의 누출을 방지할 수 없고, 저장된 내용물을 덮을 수 있는 덮개가 없어 별도로 덮개를 마련해야 하는 단점이 있다.In addition, there is a disadvantage in that the sealing is not good to prevent the leakage of the contents, and there is no cover to cover the stored contents to provide a separate cover.

본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 단면 코팅된 종이재질의 원지를 일체의 성형에 의해 제조하여 별도의 조립이 필요하지 않아서 작업시간을 단축할 수 있어 대량생산이 가능하며, 습기나 외부의 충격에도 용기의 형태를 그대로 유지함으로서 내용물의 손상을 방지할 수 있는 종이 도시락용기의 제조방법을 제공하는데 있다.The present invention has been made in order to solve the above problems, the object of the present invention is to manufacture the base paper of the single-side coated paper material by integral molding, so that no additional assembly is required to shorten the working time and mass production It is possible to provide, and to provide a manufacturing method of a paper lunch box that can prevent the damage of the contents by maintaining the form of the container intact even from moisture or external impact.
