In the third embodiment, unlike the two embodiments, the structure of the injection pressing member is different, and the structure of the nozzle part is the same as that of the first embodiment.

The injection pressing member 30 in the third embodiment includes a push button 30 attached to a valve stem (injection stem) at the upper end of the aerosol container.
This push button 30 has a stem connection portion 33 that is connected and fitted to the injection stem of the aerosol container at the center portion of the lower surface thereof, and the flow of the content liquid that extends upward from the stem connection portion 33 and extends in a substantially perpendicular lateral direction. There is a passage 30p, and a root portion 28r of the extension pipe 28 that forms a nozzle portion is rotatably held inside the outlet portion of the flow passage 30p.

And the weight member 19 is attached to this front-end | tip part.
The weight member 19 is the same as that of the first embodiment.

As a result, when the push button (pressing member) 30 is pressed, the content liquid in the aerosol container is discharged from the injection stem, passes through the flow passage 30p of the push button 30, and passes through the extension pipe (jet port) 28. It passes through the internal passage and is sprayed to the outside from its tip.
Due to the reaction of this spraying operation, the extension tube (jet port portion) 28 rotates with its root portion 28r as the rotation axis, and the extension tube 28 generates vibration due to the presence of the weight member 19 at its tip.

The extension pipe 28 and the weight member 19 in the third embodiment are also made of metal, as in the first embodiment.
Thus, the nozzle structure according to the present invention can be applied to a push button type as a pressing member.
