PROBLEM TO BE SOLVED: To easily remove a cap body from a mouth of a bottle in classification disposal of a two-piece hinged cap comprising the cap body having no weakened line and a lid to be assembled with the cap body as a technical target, whereby the hinged cap can be easily, quickly and smoothly classified. SOLUTION: The hinged cap comprises the cap body 1 having a pour-out port at the top and a lower portion of an assembling cylinder 2 to be fitted over the mouth 22 of the bottle wherein the lower portion is formed as an easily elastically deformable thin portion 3 and the lid 13 to be fitted over the thin portion 3 of the cylinder 2 with a coupling plate 19 standing on an upper surface at a rear end of an outer cylinder 17 to be undercut-coupled with the cylinder 22 via the thin portion 3 wherein an upper end of the coupling plate 19 is coupled via a hinge 20 with an upper lid 14 which opens/closes the pour-out port and a pair of thin weakened lines 21 are longitudinally formed from an upper end to a lower end of the outer cylinder 17 approximately immediately below at least one of side ends of the plate 19. |
