Abstract
A valve assembly (52) has a valve housing (64) which fits in neck (76) of container (50). Valve member (88) is slidably movable in housing (64). Housing (64) has a plurality of grooves (86) and apertures (80), which interact with flanges (92, 94, 96) to define flow paths in the valve assembly (52). The flanges (92, 94, 96), inside surface (84), apertures (80), slots (86) and valve member (88) provide a flow path through the valve assembly (52) when the valve member (88) is in its downward position inside housing (64) and seal the flow path when the valve member (88) is in its upward position. A spring (102) urges the valve member (88) to its upward position.
