ABSTRACT:
A method for forming a closure device for a container is disclosed including providing a first mold component having a first annular groove. The first annular groove is configured to form a skirt of the closure device. A plurality of ejector blades are provided and are positioned within the mold component. The blades include a notch for forming a lug on an inner surface of the skirt. The lug is back-locked relative to the mold component. A moldable material is introduced into a mold cavity to form the closure device. The device is removed from the mold component by moving the blades along a path defined by tracks formed in the mold component that is generally along a vertical axis of the mold component, wherein the path includes a radially outward component, and the moving of the blades relieves the back-lock of the lug formed on the closure device.
