HINGE CAP WITH GOOD CLASSIFIED-DISPOSABILITY

PROBLEM TO BE SOLVED: To easily tear to open first and second scores by forming the first score on an outer sidewall along both ends of a slit at both ends of a hinge coupling and by inscribing the second score on an engaging protrusion formed on an inner sidewall to face the first score. SOLUTION: A first score 31 is formed in the vicinity of both ends of a hinge coupling 7, that is a border between a first slit 30a and a second slit 30b, from an end of the first slit 30a toward an external face of an outer sidewall 6b. In addition, a second score 32 is inscribed on an engaging protrusion 8 formed on an internal face of an inner sidewall 6a at a border between the first slit 30a and the second slit 30b. That is, the second score 32 is formed from an internal surface of the inner sidewall 6a toward the outer sidewall 6b to face the first score 31. Thus tearing to open can be easy along the first and second scores 31,32.
