PROBLEM TO BE SOLVED: To provide a push-pull cap which prevents spouting of bubbles out of a spout of a container filled with a liquid that is easily bubbling. SOLUTION: A push-pull cap comprises a cap main body 31 and an over cap 32 mounted liquid-tightly onto the cap main body and capable of moving vertically, and the overcap has a spout 33 for spouting a liquid at its top and a cylindrical part 34 which surrounds the spout and dangles toward the container side. The inside diameter D1 of the cylindrical part is made larger than the bore of the spout 33, and a part being different in level 35 and inclining toward one direction is provided at the inner wall of the cylindrical part 34 so that the inside diameter D2 at the lower part of the cylindrical part becomes larger than the inside diamter D1 at the upper part. |
