<P>PROBLEM TO BE SOLVED: To provide a cap with an unfair opening-preventing function capable of confirming an unfair opening clearly at a glance from the appearance as an evidence of the unfair opening is left when a lid is unfairly opened in a circulation process and at a shop front. <P>SOLUTION: In a hinge cap, the lid 200 is openably and closeably connected to the back upper end part of a peripheral wall of a cap body 100 opened by a pull ring 144 through a hinge 300. A knob 230 for opening and closing is projected on the lower end on the opposite side to the hinge on the peripheral wall 220 of the lid. An apex of one of a connecting belt 400 for preventing the unfair opening is connected to a central apex position in the left and right direction of the knob for opening and closing through a thin weak line 401, and the upper end of the outer periphery of a locking ring 500 having a locking ring 520 on the inner peripheral face of the lower end of the peripheral wall 510 is connected at the other apex of the connecting belt for preventing the unfair opening through a thin weak line 402. The lid is closed onto the cap body, and the locking ring is locked on the lower end part of the peripheral wall of the cap body to seal it. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
