PROBLEM TO BE SOLVED: To achieve separation disposal of hinged caps without the need of large operation forces in an easy manner by making a weakening line to weaken the combination of a combination cylinder for a bottle mouth cylinder easily breakable and making breaking of the weakening line serve as a separation action for a hinged cap. SOLUTION: A vertical weakening line 5 is provided near a hinge 16 of a combination cylinder 2 of a cap body 1 along the entire height of the cylinder 2, and a horizontal weakening line 4 is extended, on a top plate 3, from the upper end of the line 5 in the circumferential direction of the cylinder 2. By lifting a cap body 12 connected to the cap body 1 through the hinge 16 by gripping the body 12, the line 4 is separated from the line 5, thereby deforming the cylinder 2, the diameter thereof being expanded, whereby the hinged cap can be separated. |
