Abstract
Abstract Deodorant or perfume is dispensed from an absorbent material whenever a water closet is flushed. The absorbent material is over an air opening in a chamber which is filled with water after the water closet is flushed so that air is expelled through the absorbent material containing deodorant or the like and a small quantity is carried into the room air. The absorbent material may form the top of a chamber normally containing air and water or may be supported on a tray which forms the top. In some embodiments, the absorbent material is initially sealed with or enclosed by water soluble materials.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
240 words
In a deodorizer, a chamber adapted to contain water and air, passage means adapted to transfer water to and from said chamber, an air vent opening in said chamber, said opening being adapted to admit air to said chamber when water is drained therefrom and to release air from said chamber when water enters said chamber, absorbent means containing air freshening evaporable material across said air opening, a support adapted to hold the chamber at a pre-selected level in the tank of a water closet relative to normal water level therein, said pre-selected level being such that the normal water level in said tank is above said water passage means and below said absorbent means, an impervious top member extending across the top of said chamber, said air vent opening being in said impervious member, said impervious member comprising a tray supporting said absorbent material above said air vent, the bottom of said tray having a plurality of elevations in the pOrtion below said absorbent evaporable material containing means, said air vent being located in a portion of said bottom above the lowest point of said bottom, said normal water level being above said air vent whereby said water entering said air vent lifts evaporable material from said bottom to said absorbent material for re-absorption, the evaporable material being lighter than water and non-miscible therewith, and the absorbent material being supported with its bottom substantially at said normal water level.
Claim 2
Dependent Claim
240 words
In a deodorizer, a chamber adapted to contain water and air, passage means adapted to transfer water to and from said chamber, an air vent opening in said chamber, said opening being adapted to admit air to said chamber when water is drained therefrom and to release air from said chamber when water enters said chamber, absorbent means containing air freshening evaporable material across said air opening, a support adapted to hold the chamber at a pre-selected level in the tank of a water closet relative to normal water level therein, said pre-selected level being such that the normal water level in said tank is above said water passage means and below said absorbent means, an impervious top member extending across the top of said chamber, said air vent opening being in said impervious member, said impervious member comprising a tray supporting said absorbent material above said air vent, the bottom of said tray having a plurality of elevations in the pOrtion below said absorbent evaporable material containing means, said air vent being located in a portion of said bottom above the lowest point of said bottom, said normal water level being above said air vent whereby said water entering said air vent lifts evaporable material from said bottom to said absorbent material for re-absorption, the evaporable material being lighter than water and non-miscible therewith, and the absorbent material being supported with its bottom substantially at said normal water level.
Claim 3
Dependent Claim
240 words
In a deodorizer, a chamber adapted to contain water and air, passage means adapted to transfer water to and from said chamber, an air vent opening in said chamber, said opening being adapted to admit air to said chamber when water is drained therefrom and to release air from said chamber when water enters said chamber, absorbent means containing air freshening evaporable material across said air opening, a support adapted to hold the chamber at a pre-selected level in the tank of a water closet relative to normal water level therein, said pre-selected level being such that the normal water level in said tank is above said water passage means and below said absorbent means, an impervious top member extending across the top of said chamber, said air vent opening being in said impervious member, said impervious member comprising a tray supporting said absorbent material above said air vent, the bottom of said tray having a plurality of elevations in the pOrtion below said absorbent evaporable material containing means, said air vent being located in a portion of said bottom above the lowest point of said bottom, said normal water level being above said air vent whereby said water entering said air vent lifts evaporable material from said bottom to said absorbent material for re-absorption, the evaporable material being lighter than water and non-miscible therewith, and the absorbent material being supported with its bottom substantially at said normal water level.
Claim 4
Dependent Claim
240 words
In a deodorizer, a chamber adapted to contain water and air, passage means adapted to transfer water to and from said chamber, an air vent opening in said chamber, said opening being adapted to admit air to said chamber when water is drained therefrom and to release air from said chamber when water enters said chamber, absorbent means containing air freshening evaporable material across said air opening, a support adapted to hold the chamber at a pre-selected level in the tank of a water closet relative to normal water level therein, said pre-selected level being such that the normal water level in said tank is above said water passage means and below said absorbent means, an impervious top member extending across the top of said chamber, said air vent opening being in said impervious member, said impervious member comprising a tray supporting said absorbent material above said air vent, the bottom of said tray having a plurality of elevations in the pOrtion below said absorbent evaporable material containing means, said air vent being located in a portion of said bottom above the lowest point of said bottom, said normal water level being above said air vent whereby said water entering said air vent lifts evaporable material from said bottom to said absorbent material for re-absorption, the evaporable material being lighter than water and non-miscible therewith, and the absorbent material being supported with its bottom substantially at said normal water level.
Claim 5
Dependent Claim
35 words
The device of claim 1 wherein the portion of said bottom in which the air vent is provided in spaced relation to said side walls, said bottom having imperforate lower portions surrounding said air vent.
Claim 6
Dependent Claim
36 words
The device of claim 1 in which said impervious member is provided with a duct adapted to conduct air from said vent to a remote discharge point, said evaporable material containing means being below the duct.
