Abstract

PROBLEM TO BE SOLVED: To provide a lunch container with which ingredients such as of curry does not overflow from the container even when the ingredients are put on rice and heating efficiency is not degraded, by providing a bent part surrounding the periphery of an opening of a housing part which contains the rice and moving upward a cylindrical reinforcing wall opposed to the periphery of the opening of the housing part by pinching the bent part. SOLUTION: A housing part 2 of a lunch container 1 is filled with a rice 7 to capacity. At the periphery of the opening of the housing part 2, a reinforcing wall 4 is provided through a bent part 3. At the opposite end of the end of the reinforcing wall 4 connected to the bent part 3, a flange-like adhesive part 5 is provided so as to seal the housing part 2 in a sterilized state. When the lunch container 1 is heated and the rice 7 contained in the housing part 2 is warmed, a film 6 is removed from the lunch container 1 and the reinforcing wall 4 is pulled upward so as to deepen the depth of the housing part 3. Then, ingredients such as of curry and the like is put on the rice 7. Thus, overflow of the ingredients can be prevented and heating efficiency is not degraded.

ことがある。In the conventional lunch container 10 as described above, for example, as shown in FIG.
When a large amount of the ingredient 8 such as curry is put on the rice 7 after removing the ingredient, the ingredient 8 may sometimes stick out from the storage section 11.
