Abstract

Disclosed herein is an air freshener of the type which releases a fragrance by permitting a scent-producing liquid to be evaporatively diffused into the surrounding atmosphere. A wick-like member, which is made from a material capable of conveying the scent-producing liquid by capillary action, is employed for the purpose of conveying the scent-producing liquid from a source located internally of the air freshener to a liquid-diffusing site located on an external surface of the air freshener. The wick-like member extends in a continuous manner from the source of the scent-producing liqiud to the liquid-diffusing site, whereby the scent-producing liquid is diffused to the atmosphere directly from the wick-like member itself. A circumferentially continuous spring-like member forms an internal liquid-tight seal in order to inhibit the inadvertent leakage of the scent-producing liquid from the air freshener. The wick-like member is maintained in a holder adapted for removable insertion into an open upper end of a base of the air freshener. By removing the wick-like member and the holder from the base, the base may be used as a receptacle for something other than the scent-producing liquid.

Claims

1. An air freshener, comprising a base having an open end, an closed end, and receiving means located between said open end and said closed end for receiving a scent-producing liquid;

conveying means for conveying the scent-producing liquid from said receiving means to a liquid-diffusing site located in said open end of said base such that the scent-producing liquid can be evaporatively diffused into the atmosphere surrounding said liquid-diffusing site, said conveying means including a wick-like member made from numerous strands of material capable of conveying the scent-producing liquid along said wick-like member from a first end located in said receiving means to a second end located at said liquid-diffusing site by capillary action, each of said strands extending continuously from said receiving means to said liquid-diffusing site such that the scent-producing liquid can be diffused into the surrounding atmosphere directly from said second end of said wick-like member at a relatively constant and uniform rate, said second end of said wick-like member being flared so as to promote the diffusion of the scent-producing liquid and matted so as to maintain the conveyance of the scent-producing liquid by capillary action;

a wick holder attached to said base, said wick holder including first holding means for holding said first end of said wick-like member such that said strands of said first end are tightly bundled so as to promote the conveyance of the scent-producing liquid along said wick-like member by capillary action and second holding means for holding said second end of said wick-like member such that said strands of said second end substantially fill said open end of said base, whereby the diffusion of the scent-producing liquid is enhanced as a result of the increased surface area of said second end of said wick-like member, said second holding means including a pan positioned in said open end of said base, said pan having a sidewall and a bottom which cooperate to define an interior chamber sized and shaped so as to receive said second end of said wick-like member, and said first holding means including a stem extending from said bottom of said pan to said receiving means of said base, said stem having a solid outer wall defining a conduit through which said strands of said wick-like member extend from said interior chamber of said pan to said receiving means of said base;

supporting means for supporting said wick holder in abutting relationship with said base, whereby an internal joint is formed between said base and said wick holder; and

sealing means for sealing said joint in a liquid-tight manner, whereby the inadvertent leakage of the scent-producing liquid from said receiving means is inhibited, said sealing means including a spring-like member having an elasticity selected such that said spring-like member is constantly and automatically urged into intimate contact with said base.

2. An air freshener according to claim 1, wherein said liquid-diffusing site is remote from said receiving means.

3. An air freshener according to claim 2, wherein said liquid-diffusing site is located on an external surface of said air freshener.

4. An air freshener according to claim 1, wherein said strands are made from polyester.

5. An air freshener according to claim 1, further comprising controlling means for controlling the diffusion of the scent-producing liquid from said liquid-diffusing site by controlling the exposure of said liquid-diffusing site to the surrounding atmosphere.

6. An air freshener according to claim 1, wherein said sealing means includes a circumferentially continuous skirt extending outwardly from said sidewall of said pan.

7. An air freshener according to claim 6, wherein said skirt extends upwardly from said sidewall of said pan.

8. An air freshener according to claim 7, wherein said supporting means removably supports said wick holder in said open end of said base, whereby said wick holder and said conveying means can be removed from said base to provide access to said receiving means for the purpose of permitting said base to be filled with potting soil and used as a planter.

9. An air freshener according to claim 8, wherein said base includes a circumscribing groove intermediate said open end and said closed end, said air freshener further comprising a generally truncated domeshaped shroud having a top opening, a bottom opening and a retainer lip disposed about said bottom opening, said retainer lip releasably engaging said groove in said base so as to removably dispose said shroud about an upper portion of said base, said shroud also having a simulated flower petal design thereon, whereby said air freshener resembles a flower.

10. An air freshener according to claim 8, wherein said supporting means includes a circular flange extending radially inward from said open end of said base, said flange releasably engaging said skirt of said sealing means when said skirt is compressed to thereby facilitate the formation of said liquid-tight seal.

11. An air freshener according to claim 9, wherein said base is translucent, whereby the level of the scent-producing liquid can be viewed through said base.

12. An air freshener according to claim 9, wherein said wick holder is removable independently of said shroud, whereby said wick holder and said conveying means can be removed from said base without removing said shroud from said base.

13. An air freshener according to claim 1, wherein said wick holder includes guiding means for guiding said first end of said wick-like member into said conduit of said stem during the insertion of said wick-like member into said wick holder.

14. An air freshener according to claim 13, wherein said guiding means includes a chamfered surface at the interface between said conduit of said stem and said interior chamber of said pan.

15. An air freshener according to claim 14, wherein said bottom of said pan has a vent hole.
