Abstract

PURPOSE: To manufacture a cap of can possessing a high hermetic sealability without using an adhesive agent, by holding a ring type flange of a synthetic resin made ring body between a cap sheet and a ring type projection provided in the upper inside of the side wall of a capped metallic cylinder.
CONSTITUTION: A specified breadth of upper part of the side wall 1a of the capped cylinder 1, prepared from a metallic sheet by the drawing work, is pushed inward so as to form the ring type projection 2. A synthetic resin made ring type body 4, provided with a ring type flange 3 in its outside of upper part is inserted to the inside of this cylinder 1, and besides, the flange 3 is fitted into the ring type hollow groove 5 formed between the projection 2 and the cap sheet 1b of the cylinder 1. After that, the projection 2 and the circumferential edge of the cap sheet 1b are pressed, so as to pinch and set the ring type flange 3 at the circumferential edge of the cap sheet 1b. On the other hand, when the cylinder 1 is formed, the lower edge of the side wall 1a is bent outward so as to form the ring type flange 14. This flange 14 is bent outward at the same time as forming the projection 2, and the ring type curl 15 is formed.
