2. Description of the Related Art Conventionally, various studies have been made on an aerosol injection device used in an aerosol injection container or the like in order to improve its injection characteristics. The component that influences the injection characteristic is the portion of the aerosol injection valve at the upper end of the aerosol injection container, and the opening / closing characteristic of the valve of the aerosol injection valve is related to the injection characteristic of the aerosol injection device. . And, an aerosol injection device used in a conventional aerosol injection container or the like has an injection head having a push button type injection beak at its upper end portion,
The ejection head is lowered to eject the contents in a desired state such as mist or foam. However, there is an on-off valve at the injection port, not at the aerosol injection valve at the upper end of the aerosol injection container, and the valve stem is normally moved upward by a coil spring biased upward. And the fluid passage is closed. Then, at the time of use, the injection head having the push button type injection beak located above the valve stem is lowered to open the lateral hole located at the intermediate portion of the valve stem, and the contents flowing into the lateral hole are The contents are sprayed from the injection port to the outside in the form of mist or bubbles without any obstacle. By the way, the target field where the aerosol injection container is used is multifaceted, and in particular, it is prohibited because it is dangerous, or technically, it is not appropriate to inject the aerosol, and in addition,
In some cases, where there is an alternative technology, the use of aerosol injection containers is avoided, but recently,
Its applications are expanding into fields that have been considered impossible. Even so, there are restrictions on the target field in which the conventional general aerosol injection container is used, and research on the aerosol injection device where it is not used in the conventional general aerosol injection container becomes important. Further, conventionally, the technique of blocking or opening the flow path has been utilized in all technical fields. However, when using the aerosol injection container, no study has been made on the practicality of directly opening and closing the injection port. In addition, the valve for directly opening and closing the injection port portion of the aerosol injection container having a relatively small diameter must be extremely small, which makes its manufacturing work difficult, and it is easy for foreign matter to get caught and However, there is a drawback that the injection fluid easily leaks. In particular, the opening of the injection port was made extremely small to facilitate atomization and injection, but a valve mechanism that blocks or opens the flow path to a part near the opening of the injection port. Since it was an extremely difficult technique to install the valve, I did not try to install the valve mechanism while recognizing the necessity.
