PURPOSE:To eliminate difficulty in removing a can lid by providing an inner cap with a spring member which is in contact with an opening periphery of a can body and which is bent and accumulates force to lift a can lid side having a cut with the opening periphery as a supporting point by a slope of the can lid. CONSTITUTION:An inner cap 5 made of synthetic resin is provided inside a can lid 2. The inner cap 5 has a top plate 5a, whose upper face is adhered and fixed to the inner of the can lid 2. The top plate 5a has a downward expanding part 5b and two parallel lines of cuts 5c are provided on the expanding part 5b while a spring member 5d with its base connected to the expanding part 5b via the cut 5c is integrally molded and the tip of the spring member 5d is positioned oppositely to a cut 4 of the can lid 2. When the can lid is tilting, an opening periphery of a can body 1 on the side of the cut 4 is still bitten into a groove 5e of the inner cap 5 on the side, but the can lid having the cut 4 comes off the groove 5e by accumulated recovery force of the spring member 5d which has been forced to be bent. |
