Description
i~L~ 7~133 FRAGRANCE ~!EN~RATO~
The present invention is concerned with the field of room odorization. In particular, it deals with a disposable device, which is electrically heated and which volatilizes perfume from porous material.
In the past, such devices have evaporated liquid perfume from reservoirs using the heat from light bulbs, as in U.S. 1,803,334 and have also 10 liquified wax impregnated with perfume, as in U.S.

2,532,~00. U.S. 2,942,09~ teaches a housing con~aining a light bulb and having deodorant tablets which are ne~71y saturated with liquid perfume each time the device is to be used. U.S. 3,080,624 15 employs a reservoir filled ~7ith perfume and topped with a wick to bring the pcrfume in contact with the hot light bulb. The disadvan~a~e of having liquid perfume in contact with hot electric light bulbs is obvious.
U.S. 3,9~3,458 makes use of a refractory cake to carry perfume oil and an electric heating element with a pilot light to volatilize the perfume.
The present invention, for the first time, presents a disposable unitary odorizer which over-comes the numerous shortcomings of the devicesheretofore employed to odorize rooms.
~' ~L2~7~3 Thc present invention is a disposahlc odorizcr comprising an electrical heating element fixedly enclosed in porous material impre~,natetl with volatile odorous substance. The odorizer wherein thc hcatin~
elcment is a ceramic coated resistor is prcferred as is the odorizer wherein the heatin~ element is a light bulh, The odorizer wherein the porous material is plaster of Paris is preferred as is the odorizer 10 wherein the porous material is molded around the heating e~e~ent. The odorizer is also preferred with a housing with means to direct the odorous substance as it volatilizes.
The odorizer which further comprises indicator 15 means for verifying activation of the heating elemcnt is preferred and the odorizer wherein the indicator means is a neon bulh wired so as to remain lighted whenever the heating element is activate~ is especially preerred as is the odorizer wherein the heating 20 ele~ent is energized by switching means.
A disposable odorizer comprisin~ a ceramic coated resistor embedded in plaster of Paris impregnated with up to about 10 wei~ht percent volatile ~erfume is an especially Dreferre~ e~bodiment of the present inven-25 tion.
The figure shows an exploded isometric perspectiveview of the total assembly of the odorizer including the housing and all internal parts.
The fi~,ure shows a side elevational view of the housing 1 of the odorizer which is preferabl~ ~ade of ! a harA translucent plastic such as ~olypropylcne, It has a series of a~ertures or slots ~ alon~, the Ipper portion to allow the escape of the volatilized odorous substance. It also has an opening or slot 3 to receive a switch. Several ventilator openin~s 4 are located on the underside of housing 1 to allow for the entrance of air from the outside of the unit so that it can pass over the scented bloc~ and out through the odor slots _ in the housing. ~ovement of air is increased by the convective action resulting fro~ the heating of perfumed hlock 44.
The figure also shows a side elevational view of the backing plate 5 with a rib means 6 to which housing 1 is permanently affixed. ~penings 7 provide a means for metal contacts 20 and 23 to project through backing plate 5 to make electrical contact with a duplex wall outlet. For~ed recesses 8 and 10 receive contacts 20 and 23 and formed pins 9, 11 and 13 serve as a fastening means for contacts 20 and 23 hy bein~ heat distorted after passing through holes 21, ~ and 28 in the contacts. Formed projection 14 serves as a support - for neon lanp 15 which is electrically connected to the contacts by means of wire 16 and through resistor 17 and wire 18, such wires passing through holes 22 and 27. Electrical current passes through contact ~3 to ~2~7~33 s~7itch 31, ~hich is af~ixed to the contact 23 ~ means of the switch contact 33. S~7itcll 31 ls .^7ired in series ~ith contact 3n through switch contact 34, so that when switch 31 is closed current flo~Js through neon lamp 15 and electrical leads 45 and 46 through rcsistive element 44 and fragrance ~loclc 43. Neon lamp lS wired in parallel with resistive ele~ent 44 is on when current flows throu~h resistive element 44. Flan~,e ~2 on switch 31 finishes the opening 3 on the housin~ 1 10 after assembly.
The ~igure further sho~ls a side elevational view of the bulkhead 36 which separates fragrance block 43 from the electrical connections. ~penings 37 are slots throu~h which contacts 19 and 26 ~ass and ar~ electrically 15 connected to the resistive element 44 by means o. leads 45 and 46 throu~h holes 27 and 77. ProJections 38 provide a ~eans hy ~7hich fragrance impre~nated plaster can be poured and held in place when hardened.
Projections 3l~ also provide a means for prevention .~ of contact T7ith electrical contacts 45 and 46 by objects inserted through openings _ and 4 in housing 1. Projection 39 protects lamp 15. Projection 4 protects resistor 17 and projection 41 ~rotects switch 31. Opening 42 for switc~ 31 is aligned with 25 openin~ 3 in housin~ 1.
