Abstract

A housing having a longitudinal aperature therethrough, and an exterior surface adapted to be securable to a container. A stem is longitudinally movable within the housing and is cooperatively conformed with the housing such that an annulus exists between a portion of the housing and the stem. The stem includes a plurality of ports allowing fluid communication between the annulus and a longitudinal cavity extending from the top end of the stem. A sealing instrumentality if included proximate a bottom end of the valve to prevent the flow of fluid into the valve annulus when the valve is in a first 'closed' position. The stem is adapted to be moved longitudinally within the housing to a second, 'open', position wherein the sealing instrumentality is released and fluid may enter the annulus and pass through the ports to exit the valve through the stem cavity.
