<P>PROBLEM TO BE SOLVED: To provide a cap configured to prevent generation of abnormal noise in opening, and a capped container provided with the same. <P>SOLUTION: The cap includes, as an inside plug 2, a body side cylindrical portion 6 fitted to an opening portion 50a of a container body 50 and a separation portion 4 continued to a tip thereof through a score 7, in which a flange 4d of the separation portion is held by an annular projection 9 extended downward from the upper end inner wall of an upper lid by screwing the upper lid into the opening portion of the container body, the separation portion is separated from the body cylindrical portion together with the upper lid when the upper lid is separated from the container body to thereby form an opening. A thin extended portion 4e is formed on the circumferential surface of the flange, so that when the flange of the inside plug is slid on the inner circumferential surface of the projection of the upper lid, the air in a space defined by the protruding portion and the flange is gradually discharged through the thin extension portion, whereby the generation of abnormal noise is prevented. <P>COPYRIGHT: (C)2013,JPO&INPIT |
