PROBLEM TO BE SOLVED: To provide a lid body and the like which reduce possibility of deformation of an outer frame and possibility of loss of a part, and is easy to clean.SOLUTION: A lid body 2 is mounted on a container main body 1. The lid body includes: a plate-like main body part 20 which covers an opening of the container main body and has an inner side surface facing to an inside of the container main body and an outer side surface on an opposite side to the inner side surface; an outer frame part 22 which is formed of material different from the main body part and is formed integrally with the outer side surface on an outer circumference part of the main body part; a flap part 30 which continues to the outer frame part, can be folded with respect to the outer frame part, and opens and closes a vent hole formed on the main body part or the outer frame part so as to communicate between an inside and an outside of the container main body with the folding; and a seal part which is formed of material different from the main body part, is formed integrally with the inner side surface on the outer circumference part of the main body part, and can be tightly attached to a peripheral edge part of the container main body so as to tightly seal the opening of the container. The main body part 20 is formed of material harder than the outer frame part 22 and the seal part, and the outer frame part 22 and the flap part 30 are integrally formed of a same material. |
