ABSTRACT:
A fluid dispenser has a fluid outlet and an ambient inlet. The dispenser includes a container having a cavity, and a regulator device within the container cavity for regulating liquid flow out of the fluid outlet. The regulator device has a cavity in fluid communication with the ambient inlet, and an air transfer orifice for placing the device cavity in fluid communication with the container cavity. The air transfer orifice is spaced apart from the ambient inlet. The regulator device also has a fluid inlet. Location of the air transfer orifice with respect to the fluid inlet is such that flow of liquid from the container cavity into the device cavity stops when the liquid in the device cavity reaches the air transfer orifice.
