Description

  The present invention relates to a paper lunch box, and more particularly, to a double-sided paper lunch box capable of improving convenience in use.

  A common paper lunch box consists of a box and a lid. In order to prevent food from leaking out of the box or foreign matter such as dust or insects from entering the box, it is common to put the food on the box and then secure the lid and the box with a rubber band. That is, in order to obtain a sealing effect, it is necessary to use a rubber band for such a lunch box, so that the cost is relatively high and the burden on the environment cannot be reduced.

  In contrast, a paper lunch box developed to reduce the cost of using rubber bands has a flaky fitting portion on one side of the lid. By inserting the flaky fitting portion of the lid into the fitting hole of the box, the effect of fixing the lid without using rubber bands can be achieved. The box of the paper lunch box disclosed in Patent Document 1 has a two-layer structure of a wall and a reinforced wall, and has a fitting opening in the wall. If the connecting wall is fitted into the fitting opening, a tightness and a stabilizing effect can be achieved. If the inside space and the fitting opening of the box are blocked by the reinforced wall, the food in the paper lunch box and the outside can be effectively isolated, but when actually used, the connecting wall is connected to the fitting opening. There is a problem that convenience when fitting is reduced because fitting may be difficult.

  The common problems of the two paper lunch boxes are as follows. After opening the paper lunch box, the lid will be tilted, so when opening the lid and trying to take the food in the box, if you put a part of food that is too much or too much on the inclined lid, the food will be Not only do they fall off the lunch box and become dirty, but they also waste food and affect environmental health. In addition, since the box and the lid are integrated, it is necessary to develop a mold having a relatively large size. Therefore, the production cost is high.
