<P>PROBLEM TO BE SOLVED: To provide an opening/closing stopper, which has a simple structure and is easy to operate, despite having an air intake mechanism, to solve the problem that a conventional opening/closing stopper without an air intake mechanism raises a necessity of forming a separate air intake on a container in addition to an opening/closing stopper of the container, and of a troublesome simultaneous operation of an opening/closing handle and the separately formed air intake for discharging a content, and that an opening/closing stopper with an air intake mechanism tends to be complicated in mechanism and operation. <P>SOLUTION: The opening/closing stopper comprises a stopper body 40, a rotary stopper 30, and a rotary stopper cap 50. A first opening 31, a second opening 32, and a rotary stopper air hole 35 are formed circumferentially on the side wall of the rotary stopper 30. Meanwhile, a stopper body opening 41 and a stopper body air hole 44 are formed on the stopper body 40. By rotating the rotary stopper 30, a closed state, a discharge state without air intake, and a discharge state with air intake are created as the openings 31, 32 and the air hole 35 on the rotary stopper 30 are matched to the opening 41 and the air hole 44 on the stopper body 40 in respective different combinations. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
