Although the weight member is provided at the tip of the extension arm portion, the design of the weight member can be freely changed.

In short, it is only necessary to place a weight member on the outer periphery of the conduction path of the nozzle hole portion as the rotation center so that one diameter direction of the rotation center is always arranged in the same direction as the upright position.
Thus, for example, if the nozzle hole has a wide injection pattern expanded in the vertical direction, the nozzle hole is the same as the upright position regardless of the posture of the aerosol container by the action of the weight member. This is because the wide spray pattern expanded in the vertical direction can be maintained.

The form of the nozzle part can also be designed freely, and in the above embodiment, it has a vertical wide injection pattern expanded in the vertical direction. For example, this has been expanded in the horizontal direction. It is also possible to easily obtain a lateral wide spray pattern by setting the wide spray pattern so that the aerosol container can be held in any posture.
In short, by changing the position of the weight member, the expanding direction can be easily changed.

  In the above-described embodiment, the main body portion of the injection nozzle is formed by combining the two members of the base end portion and the injection hole connecting portion. However, it is also possible to integrally form the main body portion and the single nozzle member. is there.

In the aerosol container, various drugs and propellants are sealed in the same manner as the conventional one. Select and seal the drugs according to various applications, and press the valve stem to spray. It is something that can be done.
As described above, according to the present invention, it is possible to provide an injection nozzle capable of always maintaining a predetermined injection pattern with a simple configuration regardless of the holding posture of the aerosol container.
