Abstract
The disclosure relates to a unitary molded article and a method for producing a multi-part closure for assembly on the neck of a container, the closure involving an axially shiftable valve element which is movable between open and closed position. All parts of the multi-part valve element are integrally molded in a common molding cavity and the various relatively movable parts are interconnected by thin annular webs which are severed and the parts placed in proper operative condition during the assembly of the closure to the neck of a container by a conventional applicating machine.
