PROBLEM TO BE SOLVED: To provide a hinge cap with improved convenience which facilitates the visual identification of whether it is opened or unopened, whose manufacturing cost is reduced with a simplified structure, which does not generate trash when opened and does not generate a protrusion after being opened.SOLUTION: A hinge cap 100 is integrally formed by a skirt part 120 and an upper lid 110 being connected by a hinge mechanism 140 and a tamper-evident mechanism 150 while it is unopened. The tamper-evident mechanism 150 includes an upper lid extension convex wall 160 and a skirt extension convex wall 170 formed in a manner to protrude from the upper lid 110 and the skirt part 120 respectively, and circumferential direction bridge strips 180 for connecting the opposing side end edges 161 and 171. |
