PUMP DISPENSERS

摘要

A pump dispenser has its outlet valve disposed immediately upstream of its dispensing nozzle (19') and at a remote spacing from its inlet valve. The movable part of the outlet valve is formed by a circular disc (214) of a valve component (206) which is push-fitted into the hollow free end of the dispenser body (13'). The disc is flexible and carried on the valve component so as to be generally transverse to the product flow path. It faces in the upstream direction and is biassed by the valve component into engagement with a downstream facing, annular valve seat (242) which is formed within the body cavity.
