Abstract
An apparatus equipped with a molding means for molding an annular liner on the inside surface of top panel of a container closure shell. The molding means includes an anvil on which the container closure shell is placed in an inverted state, and a press tool assembly which is disposed above the anvil to ascend or descend relative to the anvil. The press tool assembly includes a punch member, an excess resin counter member arranged on the outside of the punch member, a bushing member arranged on the outside of the excess resin counter member, and a sleeve member arranged on the outside of the bushing member. The sleeve member has a passage notch and a non-passage notch. A feeder nozzle is disposed to feed a synthetic resin material into the press tool assembly, the nozzle having a discharge port positioned in the moving path of passage notch. The synthetic resin material discharged from the discharge port enters into the sleeve member through the non-passage notch and is cut away from the discharge port.
