PROBLEM TO BE SOLVED: To provide a container equipped with bellows on a part of the container wherein a shrinkage amount of the bellows is defined so that a quantity of ejected liquid is constant when the liquid is taken out of the container. SOLUTION: A bellows 2 is provided on a part of a container 1. A protrusion 3 and a stopper 4 which can define several shrinkage amounts of the bellows are provided. The stopper 4 can be attached to the container and rotated, wherein a rotated position defines the shrinkage amount of the bellows 2, thereby feeding a defined quantity of liquid. Its rotation amount can be easily known by an indicator. A spring 6 works to help the shrinking bellows 2 to restore. |
