PURPOSE:To prevent a smell from being scattered from a breakage line surrounding a removal plate in a known cap with pull-ring wherein a cap body having a top plate and a lid for opening/closing a body upper face are connected by a hinge and a removal plate is provided on the above mentioned top plate to form a pull-ring attached. CONSTITUTION:A cylinder 1 formed by a cap body except a top plate pull-ring, etc., and a lid 9 are integrally formed, while a lower face of an outlet cylinder 4 of the cylinder 1 is closed and an outer peripheral part upper face is brought into contact with a lower face of an inward flange 3 to provide a thin layered plate 16 comprising water-resistant synthetic resin films laminated on and under an intermediate thin plate having smell preserving ability. While a ring-shaped breakage line 17 is assumed in the thin layered plate portion surrounded by the outlet cylinder 4, a flange plate 18 having an inner cylinder 19 fused to a lower part of the thin laminated plate outside the breakage line and fitted into an internal face of an upper end part of a first peripheral wall 2 is fused, and a removal plate 20 with a pull-ring 22 is fused to an upper face of the thin laminated plate portion surrounded by the breakage line. |
