LUNCH BOX

PROBLEM TO BE SOLVED: To provide a lunch box having a device for preventing rice from being shifted by carrying. SOLUTION: Lunch is packed in a container in which uneven projection partitions 5 and 6 are provided inside a lunch container body 2, a lunch box lid 1 is provided with uneven projection partitions 3 and 4 and the lid is closed. By the draft of the uneven projection partition part of the lunch box lid and the protoruded volume of a round surface, an appropriate pressure is applied to the uneven projections of lunch containers 5 and 6, and the partitions 3, 4 and 5, 6 hold the rice, distribute the weight of the rice in all directions independent of a carrying angle, support instable rice which is just cooked with each other and prevent shifting of the rice under the synergistic effect. For washing after use, since the recesses and projections are in a round surface structure without corners, washing is easily executed with a sponge or the like. Since a side dish container is also provided in a liquid-sealed double lid structure, it is carried together with books in a thin bag or the like. COPYRIGHT: (C)2004,JPO
