Abstract
A mold and a molding method are described for forming a closure device having a cap portion, a cylindrical plug portion extending therefrom, and a cylindrical collar extending substantially coextensively and coaxially with the plug portion spaced therefrom to provide an annular recess for receiving the open end of the container to be closed. The mold cavity is defined by mold segments and by a substantially cylindrical hollow outer core which extends into the mold cavity and defines the annular recess in the closure device between the collar and the plug portion. The mold segments include a gripping portion for retaining the closure device. The gripping portion retains the closure device while the outer core is extracted from the cavity. The gripping portion of the mold segments is then separated along with the remainder of the mold segments to remove the molded device.
