ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates in general to fluid delivery devices, and more particularly, to a fluid delivery device that is configured to automatically dispense fluid at predetermined intervals.
2. Background Art
Fluid delivery devices, such as fragrance or insect repellant dispensers have been known in the art for several years. While conventional dispensers have been readily utilized in numerous commercial markets, they have not been configured to automatically dispense a fluid at predetermined intervals. In particular, conventional dispensers are manually or electromechanically actuated by depressing, for example, a cap, a button, or a trigger mechanism. Such manually, or electromechanically actuated dispensers are cumbersome and expensive inasmuch as they have many costly components.
It is therefore an object of the present invention to provide a fluid delivery device that is configured to automatically dispense and/or volatize a fluid at predetermined intervals with mechanisms involving gas generating cells and materials, gravity force, heating elements, fans and combinations thereof.
These and other objects of the present invention will become apparent in light of the present Specification, Claims and Drawings.
SUMMARY OF THE INVENTION
The present invention is directed to a fluid delivery device comprising: a) a container for holding a predetermined quantity of fluid; b) means for generating gas within the container; c) means for cyclically dispensing fluid out of the container at predetermined intervals as well as optional means for vaporizing dispensed fluid.
In a preferred embodiment of the invention, the means for generating gas within the container comprises a gas generating cell. In this embodiment a shield may be used to substantially preclude fluid within the container from contacting the gas generating cell.
In another preferred embodiment of the invention, the means for cyclically dispensing and/or volatizing fluid at predetermined intervals comprises a one-way pressure relief valve. In this embodiment a stem may be used to direct fluid inside of the container toward the pressure relief valve.
In yet another preferred embodiment of the invention, the means for cyclically dispensing and/or fluid at predetermined intervals comprises an aperture associated with the container. Preferably the aperture is associated with a regulator to variably regulate the size of the aperture.
In a preferred embodiment of the invention, the device further comprises a heater for vaporizing the dispensed fluid. Preferably the heater is powered by a battery, a solar powered cell, or a supply of alternating current.
In another preferred embodiment of the invention, the device further comprises a fan for vaporizing the cyclically dispensed fluid. Preferably the fan is powered by a battery, solar cell or supply of alternating current.
In another preferred embodiment of the invention, the device further comprises an emanator pad associated with the container.
Preferably the device is at least partially filled with at least one of the group consisting essentially of perfume, fragrance, deodorizing fluid, insecticide fluid, sanitizing fluid, nutritional fluids, antimicrobial fluids, medication fluids or combinations thereof.
The present invention is also directed to a fluid delivery device comprising: a) a container for holding a predetermined quantity of fluid and b) means for cyclically dispensing and/or volatizing fluid at predetermined intervals out of the container.
In a preferred embodiment of the invention, the means for cyclically dispensing and/or cyclically volatizing the fluid at predetermined intervals out of the container comprises an aperture associated with the container. Preferably the aperture is associated with a regulator to variably regulate the size of the aperture.
The present invention is also directed to a fluid delivery device comprising: a) a container for holding a predetermined quantity of fluid, wherein the container includes at least one displacable flange; b) an elastomeric band seal associated with the at least one displacable flange; c) and an aperture covered by the elastomeric band seal.
The present invention is further directed to a fluid delivery devise comprising: a) a first container for holding a predetermined quantity of a first fluid, such as water; b) means for generating gas within the first container; c) a second container holding a predetermined quantity of a second fluid and a gas generating material that is activated by the first fluid; d) means for cyclically dispensing the first fluid out of the first container and into the second container; and e) means for cyclically dispensing the second fluid from the second container.
