Abstract: A method of molding a container closure providing selective fluid communication between an interior of a fluid container and an exterior environment, the method comprising: (i) configuring and closing a mold having a first cavity negatively defining a base of a container closure that includes a spout and a container mount, where the spout and container mount cooperate to define a conduit therethrough in fluid communication with an outlet orifice of the spout; (ii) injecting a first material into the first cavity to mold the base; (iii) cooling the first material in the mold to impart at least minimal rigidity to the base; (iv) reconfiguring at least a portion of the mold to define a second cavity adjacent to the first material, the second cavity negatively defining a cap covering the outlet orifice of the spout; (v) injecting a second material into the second cavity to mold the cap over the outlet orifice; (vi) cooling the second material in the mold to impart at least minimal rigidity to the cap; and (vii) r

Abstract: A closure for a container adapted to contain a liquid comprising: (a) a base adapted to be attached to an opening of a fluid container, the base including a conduit extending therethrough that is adapted to be in fluid communication with fluid contents of the fluid container when attached to the opening of the fluid container, and the base further including a spout guide defining at least a portion of the conduit and having an annular deck extending inwardly from an inner circumferential surface of the base, defining an orifice in fluid communication with the conduit; (b) a spout mounted to the spout guide for reciprocation between an open position and a closed position, the spout including a plug having a leading end adapted to allow fluid flow through the orifice when the spout is in the open position; and (c) a discrete sealing member coupled to at least one of the spout and the base, adapted to be at least partially displaced to provide a fluidic seal between at least one of the spout and the base to seal
