Abstract
A device for dispensing a liquid product as an atomized spray includes a container, a depressible dispensing head for initiating emission of the spray from the device and for terminating emission of the spray from the device, and a sequential delivery valve attached to the dispensing head. The dispensing device is configured to initiate flow of gas only into the dispensing head first when the dispensing head is depressed from a first axial position to a second axial position. When the dispensing head is depressed further toward the container to a third axial position, the dispensing device allows both liquid and gas to travel from the container into the dispensing head. When the dispensing head is released from the third axial position back to the first axial position, the dispensing device first stops flow of liquid into the dispensing head before stopping flow of gas into the dispensing head.
