PROBLEM TO BE SOLVED: To provide a resin cap achieving a sufficient reduction in weight and improving productivity by facilitating cooling.SOLUTION: A resin cap 1 comprises a cap body 2 and a tamper evidence band 3 connected to an opening end of the cap body 2 via a plurality of bridges. The tamper evidence band 3 includes a reduced weight structure 15 comprising an annular body portion 12 and a plurality of vertical ribs 13 arranged on an outer circumferential surface 12a of the body portion 12 at predetermined intervals along the circumferential direction. Accordingly, a cooling performance during molding of the resin cap 1 is improved, and a reduction in weight is achieved. |
