Therefore, they can be combined in a planar shape by connecting them together.

Further, as shown in FIG. 7, they can be combined vertically in a straight line. In this case, the upper surface engaging portion 60 and the upper surface engaged portion 70 may be combined. When combined in a straight line, the rotation direction of the main body 10 with respect to the vertical axis need not be considered. Finally, as shown in FIG. In this case, as shown in FIG. 6, when the two-dimensional combinations are combined so as to overlap each other, the upper and lower surfaces can be easily engaged with each other by moving in the vertical direction.
As described above, the lunch box X according to the present embodiment can be combined with any number in the vertical and horizontal directions to have a desired shape, and thus has a high degree of freedom during transportation. Further, the main body portions 10 are engaged with each other when assembled in the vertical direction, and the lid body 80 is not involved in the engagement. Therefore, the lid 80 is not opened and disengaged, and even if the engagement is disengaged. Since the lid 80 is closed, the contents can be prevented from spilling.

In the above-described embodiment, the side surface first engaged portion 20, the side surface first engaged portion 40, the side surface second engaged portion 30, and the side surface second engaged portion 50 are engaged with grooves facing each other. As the joint portion, the plate portion that fits into the groove is used as the engaged portion, and the upper surface engaging portion 60 and the upper surface engaged portion 70 serve as the engaging portion, and the concave portion that fits into the engaging portion as the engaged portion. However, these engagement structures can be changed as appropriate. That is, the engagement between the upper surface engaging portion 60 and the upper surface engaged portion 70 is also a groove and a plate portion that fits into the side surface first engaged portion 20 and the side surface first engaged portion 40, The engagement between the one engaging portion 20 and the side first engaged portion 40 can be a convex portion and a concave portion that fits into the convex portion. Furthermore, as an engagement structure, there are various types such as an engaging portion and an engaged portion of a hook-and-loop fastener, a recess and a protruding portion of a snap button, a hook and a hole or ring hooked on the hook, a magnet and a magnet or a magnetic body attracted to the magnet.
