．． , 7c causes the liquid L to volatilize from the surface of the vat 4a and be diffused. The amount of volatilization and diffusion of the liquid L can be adjusted by changing the rotation angle of the padded cover 8.
This can be done by changing the degree of opening between a and a. In addition, when the cover 80 surrounding wall 8b is not used,
As shown in FIG. 2, the pad cover 8 is rotated to shift the positions of the windows 6a and 3a so that the liquid does not communicate with the core Ja. Since the liquid L is sealed (liquid sealed) by the sliding surfaces of the core housing cylinder 6 and the receiving cylinder 3, volatilization and diffusion of the liquid L can be stopped. 2. FIGS. 4 and 5 are longitudinal sectional views showing another embodiment of the device of the present invention in a liquid/sealed state and in a state in which the liquid is volatilized and diffused.

In these figures, the upper opening 1la of the bottle main body 11
The bottle cap 12 is attached with a snap fit [19a,
19b in a sealed state.

The bottle cap 12 has an annular groove 12 on the outer periphery of the bottle bottle 12a.
A ring flange 16a provided on the core storage cylinder l6 is fitted into the groove L2b, and the volatile liquid L in the bottle body 11 is transferred to the bottle bottle 12a, the core storage cylinder 16, and the ring flange 16a. A double seal is provided by the sliding surfaces of the groove 12b and the ring flange 16a.
