ABSTRACT This container is a unique self-dosing and dispensing container. Through the use of a one-piece, self-aligning valve which moves from one position of closing a dispensing opening to a position of opening the dispensing opening and simultaneously closing the opening between the container and the chamber which contains the dispensing opening. The valve is operated by a change in pressure within the container. The change in pressure in the container is induced by flowing an excess of fluid from the container so as to cause a negative pressure. There are various techniques for creating a negative pressure in the container, including the use of a bellows built into the container and a squeezing of the sidewalls of the container.
