<P>PROBLEM TO BE SOLVED: To provide a degassing mechanism capable of easily opening an overcap and capable of strongly fitting the overcap to an aerosol container when a remaining gas is extracted by changing the engaging force of the overcap to the aerosol container. <P>SOLUTION: The aerosol container comprising a body, a shoulder and a securing ring fixed to the upper end of the shoulder has a mountain cup with a stem ejecting at the upper end on the inner center. An ejecting head has a top wall and a lower side peripheral wall is fixed to the stem of the aerosol container. The overcap is equipped with a top wall and a securing side peripheral wall secured to the securing ring of the aerosol container and a securing wall is formed on the peripheral wall of the securing side peripheral wall and a securing protrusion to secure the upper end of the inner periphery weakly to the lower end of an outer periphery of the securing ring of the aerosol container is arranged at the inner peripheral lower end of the peripheral wall of the securing side peripheral wall and an engaging protrusion to secure the upper end part of the inner periphery strongly to the lower end part of the outer periphery of the securing ring is arranged projectingly at the inner peripheral lower end of the securing wall. <P>COPYRIGHT: (C)2008,JPO&INPIT |
