Abstract
If the diameter of an opening side neck portion is decreased to minimize the contact surface between contents and air and a small cap is fitted on a container where there is the concern that exposure to air may alter the quality of contents in the container, there is not only the problem that a gap results between the cap top board and the container opening where adequate locking force is not available but the problem that force is required to open and close the lid, making removal and fitting troublesome.
