ングが凹凸係合しているのかも問わない。In this state, if the cap is forcibly opened without using the opening / closing tool, the opening preventing ring is engaged with the annular projection and cannot be lifted, so that the connecting piece is broken and only the cap portion is broken. It rotates, rises, and is opened. However, in the above technical means, the outer surface of the cap is not associated with the unevenness formed on the opening / closing tool.
The opening-and-closing prevention ring is provided with concave and convex portions for engaging with each other, and is engaged with the concave portion formed on the opening and closing device engaged with the cap.
Since the convex part for fitting together is projected , the opening / closing tool is engaged with the cap unevenly and the concave part of the opening / closing tool is projected.
When the opening / closing tool is rotated while being engaged with the portion , the cap is rotated together with the unsealing prevention ring in the same direction by the same angle. At this time, the engaging piece projected below the locking means of the opening / closing tool catches the convex portion and tries to push it up. Therefore, a force is applied to the unsealing prevention ring in the direction of pushing it up from below, and the unsealing prevention ring is forcibly moved in the upward direction while rotating, and gets over the projection. Therefore, the engagement state of the cap with the mouth of the container is released without breaking the connecting piece, and the opening prevention ring rises together with the cap. In this case, it is important that the opening / closing tool engages with both the cap and the opening prevention ring. It does not matter on which side the concave portion or the convex portion is formed between the cap and the opening / closing tool, and on which portion of the cap the unsealing prevention ring engages with the concave portion.
