PROBLEM TO BE SOLVED: To provide a plug-in type plastic cap for separation recovery, wherein a content adhered to the outer peripheral surface of the cap main body is prevented from splashing to the surroundings when a lid section is closed on the cap main body to re-seal the cap, and also, a thin fragile line for the separation recovery of the cap main body is prevented from being cut due to an external pressure applied to the lid section. SOLUTION: To the upper side of a cap main body 100, a lid section 200 is openably connected through a hinge section. Then, on the inner periphery at the lower end of the peripheral wall of the lid section, a fitting recess is provided, and to the internal side on the upper end of the peripheral wall of the cap main body, a top plate is connected through a thin fragile line. Also, on the upper surface of the outer peripheral edge section of the top plate, a fitting ring is provided, and this plastic cap is fitted by driving a plug in the neck section of a bottle. In such a plastic cap, a pressure receiving ring 213, which comes into contact with the upper surface of the fitting ring of the cap main body when the lid section is closed on the cap main body, is continuously or intermittently provided on the top surface of the fitting recess of the lid section. Also, a gap 214 is provided between the lower surface of the peripheral wall of the lid section and the upper surface of the peripheral wall of the cap main body. |
