The hem 42 has a cylindrical shape. The hem portion 42 has a convex portion 421 inside which comes into contact with the inner plug 3. Further, the hem portion 42 has a non-slip portion 422 on the outside.

The hem portion 42 extends to the lower end of the fixing portion 34 of the inner plug 3 and the sorting knob portion 35 in the height direction in a state where the overcap 4 is attached to the inner plug 3. That is, the hem portion 42 extends downward so as to cover the positions of the fixing portion 34 and the sorting knob portion 35 of the inner plug 3 in a state where the overcap 4 is attached to the inner plug 3.

In other words, when the overcap 4 is attached to the inner plug 3, the entire inner plug 3 is covered with the overcap 4 (see FIG. 3B). According to such a configuration, since the sorting knob portion 35 is covered with the overcap 4, it is possible to prevent the sorting knob portion 35 from being accidentally pulled when the overcap 4 is opened.

<Modification example 1>
In each of the above-described embodiments, the sorting knob portion 35 is provided on the lower side of the inner plug 3, but the sorting knob portion 35 is not necessarily provided on the lower side of the inner plug 3. It does not have to be provided, and may be provided near the upper portion or the central portion of the inner plug 3. In this case, the overcap 4 does not necessarily have to cover the entire inner plug 3, and may be provided so as to cover at least the sorting knob portion 35.

Further, it is sufficient if it is possible to prevent the sorting knob 35 from being pulled when trying to open the overcap 4, and the sorting knob 35 does not necessarily have to be covered as a whole. It may be partially covered. That is, a part of the sorting knob 35 may be exposed.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIG. The overcap 4 does not necessarily have to be configured to cover the entire inner plug 3, that is, to cover the sorting knob portion 35.
