Abstract

Abstract A night light assembly which plugs directly into an electrical wall outlet to provide low level illumination while at the same time generating an aromatic vapor whose odor is thematically related to a replaceable picture slide incorporated in the assembly and illuminated thereby. The assembly includes a shell supported by a plug projecting from its rear and insertable into the wall outlet. Housed in the shell is a low-wattage bulb, the shell being covered by a removable frame within which is nested the picture slide to be illuminated. Coated on the rear face of the slide is a translucent layer having a volatile aromatic liquid dispersed therein. The shell is vented, and as the air in the shell is heated and expanded by heat arising from the bulb, a convection current is produced which passes across the slide layer to volatilize the liquid, thereby creating an aromatic vapor which is discharged through the vent into the atmosphere.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 160 words
A night light assembly comprising: A. a shell supported by an electrical plug projecting from the rear thereof which is insertable in a wall electrical outlet; B. a socket housed in said shell to receive a low-wattage bulb which is thereby connected to said plug to produce light, said shell having upper and lower vents to permit the flow of air therethrough; and C. a removable frame having a picture slide nested therein covering the shell, the rear face of the slide having a translucent layer thereon in which there is dispersed a volatile aromatic liquid that is embedded in the layer whereby when the slide is illuminated by light from said bulb, heat emanating from the bulb produces a convection current in said shell which passes between said upper and lower vents and flows across the exposed surface of said layer to volatilize the liquid embedded therein and generate an aromatic vapor which is discharged through the upper vent.
Claim 2
Dependent Claim 160 words
A night light assembly comprising: A. a shell supported by an electrical plug projecting from the rear thereof which is insertable in a wall electrical outlet; B. a socket housed in said shell to receive a low-wattage bulb which is thereby connected to said plug to produce light, said shell having upper and lower vents to permit the flow of air therethrough; and C. a removable frame having a picture slide nested therein covering the shell, the rear face of the slide having a translucent layer thereon in which there is dispersed a volatile aromatic liquid that is embedded in the layer whereby when the slide is illuminated by light from said bulb, heat emanating from the bulb produces a convection current in said shell which passes between said upper and lower vents and flows across the exposed surface of said layer to volatilize the liquid embedded therein and generate an aromatic vapor which is discharged through the upper vent.
Claim 3
Dependent Claim 26 words
An assembly as set forth in claim 1, wherein said picture has a given theme, and the layer produces an odor which is thematically related thereto.
Claim 4
Dependent Claim 26 words
An assembly as set forth in claim 2, wherein said theme is floral, and said odor is the odor of the flower displayed in said picture.
Claim 5
Dependent Claim 23 words
An assembly as set forth in claim 2, wherein said picture is that of a given fruit, and said odor is characteristic thereof.
Claim 6
Dependent Claim 40 words
An assembly as set forth in claim 1, wherein said shell is provided with a square flange, and said frame is square and is provided with upper and lower flexible tabs which latch onto complementary latching elements on said flange.
Claim 7
Dependent Claim 32 words
An assembly as set forth in claim 5, wherein said frame and flange are provided with upper and lower notches on either side of said tabs to define upper and lower vents.
Claim 8
Dependent Claim 21 words
An assembly as set forth in claim 1, wherein said shell is configured to cause the covering frame to tilt upwardly.
Claim 9
Dependent Claim 16 words
An assembly as set forth in claim 1, wherein said layer is formed of a gel.
Claim 10
Dependent Claim 16 words
An assembly as set forth in claim 1, wherein said layer is formed of a plastisol.
