PURPOSE:To prevent e ring-shaped tab on a stopper body from being caught by the finger when a ring-shaped tab on a sealed member is pulled with the finger by making the inside diameter of the ring-shaped tab on the stopper body larger than the outside diameter of a cut groove on the sealed member. CONSTITUTION:To unseal a can closing device, a sealed member 2 is first pulled up with its ring-shaped tab 2f held with the finger to remove the sealed member 2. A stopper body l is then pulled up with its ringshaped tab 1e held with the finger to elastically deform the stopper body and remove the same from a can opening 5 so as to unseal the opening. In this case, the inside diameter of the ring-shaped tab 1e is made larger than the outside diameter of a cut groove 2d of the sealed member 2. In this way, when the ring-shared tab 2f is pulled up with the finger, the ring-shaped tab 1e is prevented from being caught and raised by the finger, thereby making the unsealing considerably easy. |
