Quantitative injection mechanism of aerosol container and aerosol product with this quantitative injection mechanism

摘要

The injection mechanism is improved and the assembly is simplified.The main chamber 4 comprises a main chamber 4 and a vertical inner circumferential surface 7C in the vertical direction, and an additional housing 7 for expansion of a chamber for expansion of the whole chamber is fitted into the main housing 4. An extension stem 8 of an integrated state in which the additional housing 7 abuts against the main stem 5 and a spring 9 for urging the additional housing 7 upward are disposed.The main stem 5 abutting against the extension stem 8 is also urged inwardly by the spring 9.An inlet valve to the quantifying chamber is constituted by an annular seal member 10 attached to the lower end portion of the additional housing 7 and an outer surface of the lower end of the extension stem 8.
