<P>PROBLEM TO BE SOLVED: To provide a cap of a container consisting of an over cap and a screw cap, the cap hardly causing container top covering failure of the over cap and loosening of the screw cap upon top-covering the over cap onto the screw cap. <P>SOLUTION: The cap 1 of the container includes: the screw cap 3 whose outer peripheral surface 3a has a concavoconvex stripe section 3d formed of a plurality of axially extending and alternately circumferentially adjacent convex stripes 3b and concave stripes 3c; and the over cap 4 for top-covering the screw cap 3, whose inner peripheral surface 4c has a concavoconvex stripe section 4f formed of a plurality of axially extending and alternately circumferentially adjacent convex stripes 4d and concave stripes 4e, the section 4f fitting the section 3d of the screw cap. Here, a slope is formed, on an upper end surface 3e of each of the convex stripes 3b of the screw cap 3, sloping downward, toward the adjacent concave stripe 3c on a screw cap 3 opening direction side. <P>COPYRIGHT: (C)2012,JPO&INPIT |
