ABSTRACT:
A liquid dispensing device includes a storage container and dome pump mechanism attached thereto for metered dispensing. A one-way valve is employed to pull liquid from the storage container into the dome for metering. An exit passageway serves as an output valve. Each time the dome pump housing is depressed, a substantially equal volume of fluid is dispensed from the container. To prevent accidental dispensing, the one-way valve in the dome pump remains normally open and unsealed to allow backflow of liquid back into the storage container pouch when pressure is placed on the dome. The user squeezes the dome and base plate together to seal the one-way valve to urge liquid out through the exit port for actual dispensing. The dome pump is integrally formed with a top portion of the exit pathway. Optionally, the base plate and bottom portion of the exit pathway are also integrally formed to facilitate manufacture and reduce costs of the pump while improving performance thereof.
