ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to air fresheners and more specifically to hanging car air fresheners conforming to specific native American symbols and having an amount of liquid scent contained within a chamber having an absorbent material for the retention of said liquid scent and wherein said chamber is substantially hermetically sealed whereby said scent can be retained for an extended period of time being selectively released by depressing a bulb having an amount of scent containing air which passes through said scent containing material before being expelled through a plurality of scent egress apertures and whereupon release of the bulb said scent egress apertures function as atmospheric air in draft apertures bringing said scent containing chamber into equilibrium with atmospheric pressure whereby said bulb and said process can be continued until the desired result has been achieved and furthermore said egress/in draft apertures can be constructed in such a manner as to be self sealing during atmospheric equilibrium.
In addition another embodiment is provided wherein said bulb is threaded into said air freshener whereby said bulb can be removed and a selectable amount of scent can be added to said scent containing material before reattaching said bulb thereby extending the life of a favored air freshener and enhancing the scope of scents which can be deposited therein.

There are other air fresheners designed to emit scent. Typical of these is U.S. Pat. No. 4,595,564 issued to Spector et al. on Jun. 17, 1986.
Another patent was issued to Traylor et al. on Jan. 9, 1996 as U.S. Pat. No. Des. 366,108. Yet another U.S. Pat. No. Des. 387,853 was issued to Little on Dec. 16, 1997 and still yet another was issued on Sep. 5, 1995 to Clayton as U.S. Pat. No. Des. 362,057.
U.S. Pat. No. 4,595,564
Inventor: Donald Spector et al.
Issued: Jun. 17, 1986
A cartridge-type aroma percolator for wafting fragrance into the atmosphere at a relatively high rate. The percolator includes a cylindrical container having a vented cap and a base provided with a raised hub housing an electric heater. Telescopically inserted into the container is a replaceable cartridge having a can whose base has a reentrant socket that complements and receives the hub. Placed adjacent the upper end of the can is a liquid-permeable toroidal insert incorporating a pad of porous material, the insert defining therebelow a chamber having a pool therein of an aqueous solution of a volatile liquid fragrance. A tube coaxial with the can extends through the hollow core of the barrier, the tube inlet being immersed in the pool adjacent the socket, the tube outlet being above the barrier. When the heater is energized, the solution in the region of the socket is caused to boil to produce a head of pressurized gas above the pool, forcing the liquid to rise in the tube and to be discharged from the outlet to shower onto the insert whereby the liquid percolates through the pad before returning to the chamber. An aromatic vapor emitted from the pad is wafted into the atmosphere through the vented cap of the percolator. A removable cover means is provided for hermetically sealing said can, and for storing the contents thereof, while the cartridge is not in use.

While these air fresheners may be suitable for the purposes for which they were designed, they would not be as suitable for the purposes of the present invention, as hereinafter described.
SUMMARY OF THE PRESENT INVENTION
The present invention discloses a device for an air freshener for use by hanging in an automobile or other location made in a variety of native American shapes. The present invention is provided with a circular bulb on its backside and further the device contains an amount of absorbent material held in a recessed space in its body for holding liquid scented oil. The scent can be dispersed into the atmosphere by selectively depressing and releasing the bulb so that an amount of air is dispelled through scent apertures into the air space surrounding the air freshener of the present invention. In an alternative embodiment, the bulb is threaded into the air freshener and contains an amount of absorbent material whereby scent oil is placed directly on the absorbent material therein which then can be displaced into the air surrounding the air freshener by pressing on the bulb with the scent passing through said air apertures.
A primary object of the present invention is to provide air fresheners in the form of native American symbols.
Another object of the present invention is to provide the aforementioned air fresheners using one of the following scents, sweet grass, cedar, lavender and sage.
Yet another object of the present invention is to provide air fresheners with means for discharging a reservoir of the original scent.
Still yet another object of the present invention is to provide air fresheners having a chamber for storing an amount of scent.
Yet another object of the present invention is to provide air fresheners having a bulb for discharging an amount of stored scent.
Additional objects of the present invention will appear as the description proceeds.
The present invention overcomes the shortcomings of the prior art by providing hanging air fresheners conforming to specific native American symbols and having an amount of liquid scent contained within a chamber having means for selectively releasing said scent into the atmosphere by depressing an integral bulb ejecting an amount of scent through a plurality of scent egress apertures and upon release of the bulb said scent egress apertures function as atmospheric air in draft apertures bringing said scent containing chamber into equilibrium with atmospheric pressure whereby said bulb and said process can be continued until the desired result has been achieved.
In addition another embodiment is provided wherein said bulb is threaded into said air freshener whereby said bulb can be removed and a selectable amount of scent can be added too said scent containing material before reattaching said bulb thereby extending the life of a favored air freshener and enhancing the scope of scents which can be deposited therein.
The foregoing and other objects and advantages will appear from the description to follow. In the description reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. These embodiments will be described in sufficient detail to enable those skilled in the art to practice the invention, and it is to be understood that other embodiments may be utilized and that structural changes may be made without departing from the scope of the invention. In the accompanying drawings, like reference characters designate the same or similar parts throughout the several views.
The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is best defined by the appended claims.
