<P>PROBLEM TO BE SOLVED: To provide a container with cap satisfactorily maintaining an anti-loosening function of the cap even when the cap is repetitively attached and detached. <P>SOLUTION: In the container with cap, the cap 3 is provided with an inner cylinder 3b screwed with an engagement part n provided on an outer peripheral surface of a mouth part 1c of a container body 1 and an outer cylinder 3c surrounding the inner cylinder 3b and concentrically disposed. A large projecting part 1c<SB POS="POST">3</SB>protruding radially outward of the mouth part 1c, and a small projecting part 1c<SB POS="POST">4</SB>disposed at an interval in the circumferential direction from the large projecting part 1c<SB POS="POST">3</SB>and having a protrusion amount lower than that of the large projecting part 1c<SB POS="POST">3</SB>are provided in a base pedestal part 1c<SB POS="POST">2</SB>of the mouth part 1c. A stopper 3b<SB POS="POST">1</SB>that collides with the large projecting part 1c<SB POS="POST">3</SB>to complete screwing of the cap 3, and an anti-loosening protrusion 3b<SB POS="POST">2</SB>crossing over the small projecting part 1c<SB POS="POST">4</SB>to flexibly deform the inner cylinder 3b directly before the completion of screwing and engaging with the small projecting part 1c<SB POS="POST">4</SB>on completion of the screwing to keep contact pressure therebetween, are provided in the inside wall of the inner cylinder 3b. <P>COPYRIGHT: (C)2012,JPO&INPIT |
