Lunch box is a kind of box specially used to hold rice, also called lunch box, which is mostly made of aluminum, stainless steel and plastic. Origin: Yang Shuo? The fifth paragraph of Three Thousand Jiang Lishan: "The rice in the lunch box is gurgling."

Lunch boxes include plastic lunch boxes, insulated lunch boxes and ordinary lunch boxes.

The predecessor of lunch box is food box, which is a big box used to hold food, utensils or other gifts. With the development and change of the times, the food box has completely faded out of people's lives and become a collection in the antique market.

Ancient gentry and celebrities went out to visit friends, or participated in the activities of poetry clubs and literary clubs, and drank with close friends. They often prepare some dishes and fruits as appetizers in advance. In early spring, literati go out for an outing, and they also bring food, wine and delicacies for a picnic. The food box is a long carrying box specially used to hold food, wine and vegetables, which is easy to carry and walk. It is made of wood, bamboo, enamel, lacquerware and other materials, mostly wood.

In particular, rosewood, Huang Huali, chicken wing wood, acid branches and other hardwoods with fine texture and smooth color are strong and tough, and the lunch box made of them is resistant to bumping and has a certain weight, so it is not easy to shake when picking and lifting. In addition, most ancient furniture is tenon-mortise structure, and hardwood has unique advantages in splicing and production.

Exquisite hardwood boxes can not only be watertight, but also make full use of the inherent texture and color of wood in appearance, giving people an elegant and solemn feeling, which is both beautiful and practical.

Lunch boxes are evolved from lunch boxes. With the historical development of society, the role of lunch boxes in people's lives has been replaced by lighter lunch boxes.
