Abstract

밀폐 가능한 도시락상자에 따뜻한 채로의 식품을 수납하면, 식품이 식어짐에 따라서, 본체 내부의 압력이 낮아지며, 뚜껑을 열기 어렵다고 하는 문제가 있었다.When food is kept warm in a lunch box that can be sealed, there is a problem that as the food cools, the pressure inside the main body decreases and the lid is hard to open.

또 도시락상자에 넣은 식품을 뚜껑을 덮은 채로 전자렌지에서 가열하면, 파열하므로 위험하였다. 그러나 뚜껑을 열어서 가열하면 식품의 표면이 건조하여 풍미가 떨어진다는 문제점이 있었다. 이 발명은 이들의 문제점을 해결하는 것을 목적으로 한다.In addition, when the food in the lunch box is heated in the microwave with the lid closed, it was dangerous to rupture. However, when the lid is opened and heated, there is a problem in that the surface of the food is dried and the flavor falls. This invention aims at solving these problems.

도시락상자의 뚜껑(1)에 본체(2)의 내부와 외부와의 압력차가 생겼을 때에 열리고, 압력차가 없을 때에는 닫히는 압력조정밸브(3)를 마련했다.A pressure regulating valve 3 was provided on the lid 1 of the lunch box, which opens when a pressure difference between the inside and the outside of the main body 2 occurs and closes when there is no pressure difference.
