<P>PROBLEM TO BE SOLVED: To provide a degassing mechanism of an aerosol container which enables a content to be securely used without causing an overcap to depress a jetting head when content remains, and allows residual gas to be extracted by the operation of a pressing member of the overcap when the residual gas is extracted. <P>SOLUTION: The aerosol container includes an engaging part on a shoulder part, and the overcap is composed of a lid body and the pressing member. The lid body includes a top wall, and a support cylinder of the pressing member which is vertically formed on the top wall. Threads are arranged at the upper part of the inner circumference of the support cylinder. The pressing member includes a thread-engaging cylinder and a bottom wall continuous with the lower end of the inner circumference of the thread-engaging cylinder. Threads threadedly engaging to the threads of the support cylinder of the lid body on the outer circumstance of the thread-engaging cylinder, and a depressing rib is arranged on the lower face of a bottom wall. The pressing member is rotated and lowered relative to the lid body and thereafter the overcap is mounted on the engagement part of the aerosol container, so that the depressing state of the jetting head is maintained. <P>COPYRIGHT: (C)2008,JPO&INPIT |
