Abstract
An anti-refill closure assembly comprises a closure body having an upper spout portion and a lower fitment portion configured for securement to an associated container. The closure body defines at least one flow passage through which liquid from the container enters the closure body. A reciprocable valve member is positioned within the closure body for movement between opened and closed positions. In the opened position of the valve member, liquid from within the container flows into the closure body through the at least one flow passage, and past the valve member outwardly through the upper spout portion. In the closed position of the valve member, the valve member acts to prevent the reverse flow of liquid from the outer spout portion back through the valve body and into the associated container. The reciprocable valve member acts to permit normal dispensing of liquid from within the container in the open position of the valve member, but acts in the nature of a one-way check valve to inhibit and prevent flow of liquid through the closure body back into the container.
