PROBLEM TO BE SOLVED: To provide a plastic cap which does not require a large force on uncapping and which can be easily uncapped by hands without use of special tools and further which is improved in the tamper-evident property. SOLUTION: In a plastic cap constituted of a cap body 1 provided with a skirt 4 extended down from the peripheral edge of the top plate and a ring- form member 2 surrounding the peripheral part of the external face of the skirt 4, a plurality of axially stretching notches 9 are formed at every distance in the peripheral direction, at the skirt 4 of the cap body 1. A part of the ring- form member 2 is integrally connected and fixed to the external face of the skirt 4 of the cap body 1 and the other parts are connected to the cap body 1 through a plurality of breakable bridging parts. Although the cap body 1 and the ring-form member 2 are separated from each other through a peripheral cut face 10 but these are arranged to closely contact each other at the cut face 10. A flexible flap 31 projecting to the radial inside is formed at the lower end of the ring-form member 2. |
