ABSTRACT:
Dispensers are provided of the type which include a flow path through which liquid must pass to leave the dispenser. After the dispenser has been actuated to dispense, the flow path then receives reverse flow as the dispenser recovers ready for the next dispensing. This reverse flow limits the possibility of dripping from the dispensing outlet. A flow controller in the flow path automatically adjusts to have little or no interference to the flow of liquid leaving the dispenser and then positions itself to slow down the rate of reverse flow into the dispenser. The dispenser is suitable for more viscous liquids.
