A discharge valve for a bottle or other container associated with a fluid
dispensing system that substantially prevents spillage of fluid
composition from the container when it is withdrawn from the dispensing
system is provided according to the invention. A valve body contained
within the discharge valve is engaged by a hollow probe extending from
the dispensing system when the container is operatively connected to the
discharge system to automatically open the valve. When the container is
withdrawn from the fluid dispensing system for, e.g., replacement or
servicing, the probe of the dispensing system disengages the valve body,
and a biasing means such as a compression spring within the valve
assembly closes the valve very quickly. The valve body and valve seat of
the valve assembly are designed in such a fashion that proper alignment
and closure of the valve body with respect to the valve seat is achieved
to provide a fluid-tight seal without use of a gasket or other
elastomeric seal disposed between the valve body and valve seat to
facilitate the fluid-tight seal.
