Abstract
A fluid dispensing system includes a pump for pumping fluid from a container. The pump has a vent opening for venting air into the fluid in the container to normalize pressure inside the container as the fluid is pumped. An intake shroud is coupled to the pump, and the shroud includes a channel opening to draw fluid from the container into the pump in a straw-like manner. A baffle is positioned between the vent opening and the channel opening of the shroud to reduce ingestion of the air into the pump so as to reduce short or inconsistent dosing of the fluid when pumped.
