Abstract

PROBLEM TO BE SOLVED: To provide a screw-out container which is designed to achieve the recycling of the used members by allowing the synthetic resin part, functioning as a screw-out portion, to easily separate from the metal part, functioning as a container at the time of disposal, whereas they cannot be separated during normal usage. SOLUTION: A protruding part 7a of a middle cylinder 7 composing a metal portion of this screw-out container 1 is idly connected to a recessed slot 2a of a base cylinder 2 composing a synthetic resin part. The revolving torque to release their engagement is set to a larger value than the revolving torque to move up and down a receiving body 5, and to a smaller value than the revolving torque to idle the receiving body 5 and an external cylinder 4. Therefore, when the container 1 is in use, the synthetic resin part and the metal part are securely connected, and when the container 1 is forcible turned with a larger amount of revolving torque than in normal use, the middle cylinder 7 can be removed from the base cylinder 2 so that the synthetic resin part and the metal part can be easily separated.
