Abstract
An annular protruding portion (17) is provided around an inner plug (13) at a radial interval on an annular horizontal wall portion (20) of a cap body 4. Between an annular flange portion (43a) of the inner plug (13) and the annular protruding portion (17), an annular accumulating groove portion (33) is provided. Particularly in the case of a liquid content, the liquid content may be scattered from within a cylindrical guide portion (42) when a lid member (5) is placed after use. The liquid content, however, is blocked by the annular protruding portion (17) and prevented from flowing further outward, while interfering with a top surface portion (51) and a cylindrical scattering suppression portion (55) of the lid member (5). Thus, downward flow of the liquid content along the outer wall surface of the annular horizontal wall portion (20) of a main cap member (11) can be suppressed.
