<P>PROBLEM TO BE SOLVED: To simplify the structure and production of a whole housing and to efficiently reset after a constant volume injection as to the constant volume valve mechanism of an aerosol type product. <P>SOLUTION: A constant volume injection units 7-9 are installed on the bottom tubular part 4b for mounting a content inflow tube of widely used inconstant volume valve mechanisms 1-6. The units comprise a ball valve 9 which moves to a valve seat 8c side by the flow of a content from a tube 10 when a constant volume of the content is injected, a bush 8 with a valve seat and a passage 8d for releasing the condition where the ball valve is adhered to the seat after it is moved and an additional housing 7 with a quantitative chamber 7c where the ball valve is stored. <P>COPYRIGHT: (C)2010,JPO&INPIT |
