A dispensing system is provided for a container having an opening to the interior. The container has a sealable seat around the opening and a thread. A closure is disposed on the container. The closure defines a thread that is threadingly engaged with the container thread for accommodating movement of the closure between a lowered position and an elevated position. The closure defines a dispensing passage for establishing communication between the container opening and the exterior of the closure. The closure includes a dispensing valve disposed in the dispensing passage for opening to dispense fluid therethrough and for closing to occlude flow. The closure includes an occlusion member inwardly of the valve in the dispensing passage to sealingly engage the container seat and prevent flow from the container opening into the dispensing passage below the valve when the closure is in the lowered position and to permit flow into the dispensing passage when the closure is in the elevated position.
