Abstract

Abstract A replaceable air freshener primarily for use on the tiled wall of a bathroom or kitchen. The air freshener is formed by a transparent plastic face film laminated to a transparent plastic backing film to create a laminate whose dimensions match those of a standard tile. The rear surface of the backing film has a low tack, clear adhesive thereon whereby the laminate may be adhered to a selected tile on the wall or readily removed therefrom. The face film is constituted by a polymeric matrix having myriad cells dispersed therein impregnated with a volatile fragrance which is slowly released from the face film into the atmosphere of the room. Screened on the front surface of the backing film is an artwork which is visible through the face film and has a background field imparted thereto by the color of the tile onto which the laminate is adhered so that the artwork is then in harmony with the tiled wall. The emitted fragrance from the face film is thematically released to the artwork so that should the artwork be the Xmas tree, the fragrance will be that of pine.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 138 words
An air freshener adherable to a wall tile or other substrate comprising a transparent laminate constituted by a transparent plastic face film inpregnated with a volatile fragrance that is slowly released therefrom, the fragrance being in a concentration resulting in a relatively prolonged emission and a transparent backing film laminated to said face film in a manner which does not impair the transparency of the laminate, the front surface of the backing film having an artwork imprinted thereon which is effectively sandwiched between the face film and the backing film and thereby protectively sealed, and a low-tack, pressure-sensitive, clear adhesive layer on the rear surface of the backing film whereby the laminate may be adhered onto a smooth substrate and later pulled therefrom when the fragrance is exhausted, the surface of the substrate being visible through the laminate.
Claim 2
Dependent Claim 138 words
An air freshener adherable to a wall tile or other substrate comprising a transparent laminate constituted by a transparent plastic face film inpregnated with a volatile fragrance that is slowly released therefrom, the fragrance being in a concentration resulting in a relatively prolonged emission and a transparent backing film laminated to said face film in a manner which does not impair the transparency of the laminate, the front surface of the backing film having an artwork imprinted thereon which is effectively sandwiched between the face film and the backing film and thereby protectively sealed, and a low-tack, pressure-sensitive, clear adhesive layer on the rear surface of the backing film whereby the laminate may be adhered onto a smooth substrate and later pulled therefrom when the fragrance is exhausted, the surface of the substrate being visible through the laminate.
Claim 3
Dependent Claim 18 words
An air freshener as set forth in claim 1, wherein said fragrance is thematically related to the artwork.
Claim 4
Dependent Claim 30 words
An air freshener as set forth in claim 1, wherein said backing film and said face film each have a thickness in the range of about three to six mils.
Claim 5
Dependent Claim 24 words
An air freshener as set forth in claim 2, wherein said artwork has a floral subject matter, and the fragrance is a floral aroma.
Claim 6
Dependent Claim 37 words
An air freshener as set forth in claim 1 in combination with a wall tile having a smooth surface wherein said laminate is of substantially the same dimensions as said tile and is adhered to said surface.
Claim 7
Dependent Claim 19 words
The combination as set forth in claim 5, wherein said tile is a ceramic tile having a glazed surface.
Claim 8
Dependent Claim 25 words
The combination as set forth in claim 5, wherein said tile surface has a solid color and effectively forms a ground field for said artwork.
