Abstract
A closure is provided for the opening to a container. The body defines a discharge aperture communicating with the housing. A housing is disposed on the body for movement between a lowered position and an elevated position. The housing defines a dispensing passage for establishing communication between the body discharge aperture and the exterior of the housing. The housing includes a dispensing valve disposed in the dispensing passage for opening to dispense fluid therethrough and for closing to occlude flow. The housing includes an occlusion member or plug between the valve and the body discharge aperture to prevent flow from the discharge aperture into the dispensing passage below the valve when the housing is in the lowered position and to permit flow into the dispensing passage when the housing is in the elevated position.
