Embodiment Construction

[0029] Referring now to the accompanying drawings, figure 1 An embodiment of a dispensing device 100 is illustrated. Dispensing device 100 generally includes a container 102 attached to a dispensing head 104 . The dispensing head 104 includes a spray opening 106 from which the liquid product stored in the container 102 can be dispensed or sprayed. During use, a user may press the dispensing head 104 relative to the container 102 to cause the liquid product stored in the container 102 to be sprayed from the dispensing head 104 , and more specifically from the spray opening 106 on the dispensing head 104 .

[0030] Although the figures illustrate embodiments that include dispensing devices with the spray direction oriented at right angles to the direction of actuation of the dispense head, other non-illustrated embodiments that are within the scope of the present disclosure include orientations oriented at right angles to the direction of actuation. Spray directions for other ...

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.

Description

technical field [0001] The present disclosure generally relates to devices and methods for producing sprays, and more particularly to devices and methods for producing atomized sprays of liquid products. Background technique [0002] Devices for dispensing liquids are generally known in the art. Such conventional devices generally include a container for storing a liquid product and a device for spraying the liquid product from the container through a dispensing head or nozzle. Such conventional delivery equipment typically includes a reservoir of pressurized gas stored in a container. Pressurized gas is used as the propellant to force the liquid product out of the container. [0003] Such conventional devices typically include a dispensing head including a depressible pump or actuator for manual manipulation by a user. By depressing the dispensing tip, the user can selectively open a valve or other mechanism that allows a pressurized gas or gas propellant to force the li...
