1. A container including a container main body and a lid corresponding to the container main body, the container comprising:
- a content-amount determination device that determines the amount of an object contained in the container main body;
an information storage that stores information on the determined amount of the object; and
a lid detection device that detects whether or not the container main body is sealed by the lid;
wherein the information storage stores the information on the amount of the object determined by the content-amount determination device at the time when the container is brought from the state in which the container main body is not sealed by the lid into the state in which the container main body is sealed by the lid.
