<P>PROBLEM TO BE SOLVED: To fixate and stabilize the constant jetting amount of a content relative to the constant volume valve mechanism of an aerosol product. <P>SOLUTION: A content passage from a quantitative chamber A to the inside of a container is provided with a valve operating portion including a ball valve 9 and a valve seat 7b for setting the passage in a closed condition during a rest mode. When a liquid gas mixed in the content filling the chamber A is evaporated to reach the same pressure level as that of the gas phase in the inside of a container body, the valve operating portion including the valve 9 and the seat 7b prevents the content in the chamber A from flowing back to the content liquid level of the body and causes not to reduce the jetting amount of the content during the next operation mode. <P>COPYRIGHT: (C)2010,JPO&INPIT |
