Abstract

A valve assembly for a dispensing container includes a closure body detachably coupled to a co-injected valve. The closure body includes a main closure body coupled to a closure cap via a flexible hinge. The co-injected valve includes a valve head and a valve frame. The valve head includes a valve head portion with multiple valve head slits, a sleeve portion, and a peripheral sealing flange. The valve frame is permanently coupled to the valve head and includes a radial ledge and a radial wall that support the peripheral sealing flange of the valve head. The co-injected valve is fabricated via a two-step injection molding process. The first step includes fabricating the valve frame from a first injection material, and the second step includes fabricating the valve member from a second injection material.
