<P>PROBLEM TO BE SOLVED: To provide an overcap for an aerosol container which prevents an overcap from dislocating from the aerosol container when a residual-gas extracting mechanism pushes a stem down to extract a residual gas in the state that the overcap fits to the aerosol container. <P>SOLUTION: The overcap for the aerosol container 10 has a plurality of guide pillar parts 14, arranged to be projected, which extend along the direction of the central axial line O of the ovecap 10 in the range of the upper part to the lower end of the side of a top board part 11, in the outer peripheral face of a fitting cylindrical part 12 fitting to the aerosol container 20, by being spaced out circumferentially; wherein a crossing ridgeline part 15c, which is formed by the lower-end opened face 15a and the inner peripheral face 15b of a ring member 15, is connected so that it can be extracted in each upper part of the guide pillar parts 14; the ring member 15 is arranged coaxially with the central axial line O, and the inner diameter of the ring member 15 passes the outer end in the diameter direction of the overcap 10 of each guide pillar part 14 and also is equivalent to the diameter of a virtual circle centering on the central axil line O. <P>COPYRIGHT: (C)2008,JPO&INPIT |
