• the mounting ring when attached, the mounting ring is screwed into the mouth, and the inner plug 4B is restricted from rotating relative to the mouth 2B, so the plug mechanism 6B is restricted from rotating relative to the container body 3A.
• the above-mentioned engagement configuration also prevents the inner plug 4B of the container 7B of this embodiment from rotating when the cap is opened or closed. Furthermore, because the plug mechanism 6B is removable, the contents in the storage section 1 can be used up to the last drop.
• the user when attaching the plug mechanism 6B, the user does not need to consciously align the hanging pieces 49B with the band-shaped groove 26B; simply by rotating as shown in FIG. 16, some of the hanging pieces 49B, 491 and 493, automatically engage with the band-shaped groove 26B as the piece rotates. This makes it easier to attach the plug mechanism 6B to the container body 3B.
