<p>PROBLEM TO BE SOLVED: To provide a cap for a PET bottle, a container or the like whose lower ring can be easily removed without a tool or the like together with the cap, wherein the cap once unsealed can be known at a glance and can be opened/closed, a form of the cap does not largely differ from that of a conventional one and the cap can be manufactured at a low cost. SOLUTION: Bridge regions (c1), (c2) and (c3) are folded to hook on a region (d) of a PET bottle, a container or the like, and a plurality of upper and lower portions of the bridge (c) are coupled with the inside of the cap and the lower ring of the cap respectively. The bridge region (c1) hooks on the region (d) of the PET bottle, the container or the like when unsealing, thereby cutting a cut portion (e) of the cap. Then the bridge (c) stretches to allow the bridge region (c2) to enter a gap between the cap (a) and the lower ring (b), thereby allowing the ring (b) to be removed at the same time.</p> |
