Abstract
Abstract A metering device adapted to be secured to a container of fluid comprising a housing having a main body portion and a reservoir portion of lesser dimensions than said main body. The housing has a shoulder forming a first valve seat. The reservoir portion has a second valve seat. A valve assembly is disposed mainly in said housing and has a valve head engageable with the second valve seat and a valve ring engageable with the first valve seat. A rigid stem connects the valve head with the valve ring and helical springs under compression normally urge the valve ring against the first seat and the valve head out of contact with the second valve seat.
