欠点がある。Recently, container lids have become popular, with a tear weakening line on the container lid body that extends from the tear-off tab protruding from the skirt of the container lid all the way to the top surface, and which can be easily opened by pulling the tear-off tag. are doing. When opening this type of container lid, it is necessary to apply a considerable amount of force to pull up the tear-off tab, so measures have been taken to make opening the tear-off tab easier by making the tear-off tab long and attaching a suitable gripping piece. It is being However, these measures have the disadvantage that a lot of waste occurs when the container lid is preformed from sheet metal, resulting in an increased cost of the container lid.

, the pre-formed body is held for 5 days when passing through, and the pre-formed body is received C
In order to deliver the preformed body 58 to the tension forming and joining means 16, the preformed body 58 is not held when passing through the preformed body holding area A. However, the other half of the holders 52a hold the preformed body 58 when passing through the preformed body holding area A, and pass through the other preformed body holding area Bi in this state and receive the preformed body. CK is operative to deliver the preform 58 to the tension ring forming and bonding means 16. Therefore, in this embodiment, the holder 62a and the sliding body 64 that fixes the holder 62a are arranged in the cam groove 5 in the region 64.
0, it is gradually retracted from the normal position to the inner position in the radial direction,
In the region 66, the cam groove 50 is configured to gradually return to its normal position radially outward.
