Abstract: The lid shaping device includes: container placing table 111; container lifter; lid shaping unit 112 including container mouth press 119, annular coil spring 123 arranged in a cylindrical holder, and pusher provided above the annular coil spring and having spring pressing inner circumferential surface 127; and pusher driver. The device operates in the order of first lifting by the container lifter until upper part or middle part of the lid skirt is located on the inner side of the annular coil spring, lowering of the pusher for lowering the container until the spring pressing inner circumferential surface reduces the diameter of the annular coil spring, and second lifting by the container lifter for lifting the container until the lower end of the lid skirt is located on the inner side of the annular coil spring.
