Abstract: An apparatus is provided for containing a fluid, and for controlling the release and flow of the fluid. The apparatus includes a container having a mouth, a neck with a circumferential sealing region on its inner surface, a body, and a resistance stop. The apparatus further includes a barrier flap which can significantly arc transverse to its length, disposed within the neck of the container, and hingedly pivot between “open” and “closed” positions. The barrier flap is cooperative with the circumferential sealing region and the resistance stop within the neck. Squeezing the body increases internal pressure within the container, resulting in a release of the barrier flap past the resistance stop, allowing the fluid to flow out of the container. Also, squeezing the neck causes arcing and release of the barrier flap, allowing the fluid held in the container to flow past the barrier flap and out of the container.
