Abstract
"TOILET BOWL DISINFECTANT AND/OR SANITIZING DEVICE"
ABSTRACT OF THE DISCLOSURE
Conventional disinfectant and sanitizing dis-pensers for toilet bowls are usually suspended within the tank and continually add material to the water in the tank which is wasteful and unnecessary. The present device is a plastic container situated normally just below the water level in the tank and having two compart-ments separated by a finely woven cloth or synthetic membrane. One compartment or cavity is sealed and has a chemical therein and the other cavity is provided with a small combination water inlet and breather hole, and is also provided with a syphoning tube extending through the wall of the other cavity in sealed relationship there-with. The syphoning tube is connected to a venturi tube to form a venturi effect and which is situated serially along the length of the conventional filler tube and one end of this filler tube is engaged within the tank over-flow pipe leading to the bowl. The other end of the filler tube is connected to the conventional filler valve in the tank. The water enters the breather cavity and passes through the membrane and dissolves the chemical therein and the solution of dissolved chemical and water passes through the membrane into the breather cavity by osmosis. When the toilet is flushed, water flows through the filler tube and the venturi effect sucks the water and chemical solution from the breather cavity and mixes same with the water which is entering the toilet bowl to provide adequate chemical to sanitize and disinfect and also to provide ample water for a proper seal.

Description
~303Z99 "TOILET BOWL DISINFECTANT AND/OR SA~ITIZING DEVICE"
B~CKGROUND OF THE INVENTION
This invention relates to new and useful improvements in sanitizing ana/or disinfecting devices for toilet bowls.
Conventionally, such devices include a liquid or powdered chemical continually feeding into the water within the toilet tank so that if a relatively long period extends between flushing actions, then the con-centration of chemical within the tank increases. And furthermore some of these chemicals affect the components in the toile tank.
Another disadvantage of conventional devices is that the entire tank of water is disinfected, the major-ity of which passes downwardly through the toilet bowl during the fluæhing action with very little remaining for tha disinfecting aspect. And although the tank may be disinfec~ed and/or sanitized, the toilet bowl is not necessarily disinfected.
Another disadvantage of conventional devices is that the chemicals used in this dispensers are pH
dependent. This means that a pH of 6.0 H.T.H. chlorine has an approximate effectiveness of HOCl of 95%. However ~3~329~
at a pH of 8.5 you are left with an HOCl of approximately 10% effectiveness and since most of the water~ used in this country, have been treated with H.T.H~ chlorine by the distributing water plants, the pH range in most locations is around 8.0 to 8.2 and it is almost imposs-ible thexeore for these products to work at that high pH
level.
~ he pres~nt device overcomes these disadvan-tases by providing a device which although resident with-in t~e tank, is nevertheless only operative during the replacement of the water seal through the overflow pipe during the flushing cycle thus reducing by a considerable amount, ~he amount of chemical used.
SUMMARY OF THE INVENTION
One aspect of the invention is to provide a sanitizing and/or disinfectant dispensing device for toilet bowls having a water tank operatively connected between a source of water and the bowl, having a conventional flushing assembly; including an overflow pipe or conduit operatively connected to the bowl and a fill1ng tube operatively extending between the source of water and the overflow pipe for replacement of the water seal in said bowl during the flushing cycle: said device comprising in combination a container having a chemical :: :

~3~?3z99 holding cell and a breather cell with a permeable screen membrane therebetween, said container normally being just below the high water level in said tank, combination water inlet and ~reather hole means formed through the wall adjacent the upper side of said breather cell, and means operatively extending between ~aid breather cell and said filling tube to extract a so~ion of water and dissolved chemical from said breather cell during said flushing cycle as well as during the replacement of said water seal through said overflow pipe.
Another advantage of the invention is to pro-vide a device which is extremely simple in construction, economical in manufacture, and otherwise well suited to the purpose for which it is designed.
With the foregoing in view, and other advan-tages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, the invention is herein described by reference to the accompanying drawings forming a part hereof, which includes a de criptlon of the best~ mode known to the applicant and of the preferred typical embodiment of the :~principle~ of the present invention, in which:

DETAILED DESCRIPTION
. . .
Proceeding thereore to describe the invention in detail, reference should first be made to Figure 1 in which 10 illustrates part of a toilet tank having a conventional water connection 11 extending upwardly through the base 12 of the tank into a filler valve assembly 13 which is conventional in con~truction and which includes a filling tube 14 extending into the upper open end of an over10w pipe 15. This tube 14 normally replenishes the water seal within a toilet tank during the flu6hing cycle, when it takes place, while the tank is beiny fiIled to the normal water levPl indicated by refer-nce character 16.
~3;~
The invention collectively designated 17 is suspended by clip 18A or other conYentional means, within the tank and just below the normal water level 16.
In detail, the dispensPr 17 includes a casing comprising two halves 18 and 19 which are similar and substantially rectangular when viewed in side elevation and which form a chemical holding cell 20 and a breather cell 21~ Each casing half includes a side wall 22, vert-ical edge walls 23, a base wall 24 and an upper wall 25 with a flange 26 preferably formed around the edges of these walls on the open side of the cells 20 and 21 so that the two halves can be sealably connected together as by heat sealing or adhesive, with a permeable screen membrane 27 being sealed therebetween thus closing off the two cells one from the other with the exception of the permeability of the screen.
In cell 20 which is the chemical holding cell, a chemical indicated at 28 is placed prior to the sealing of the two halves together. While this chemical may taXe several forms, it is proposed that a chlorine based chem-ical such as HALE~E (Trademark) be used. HAL$~E is not pH dependent and will therefore operate more effectively than H.T.H. or other chlorines with EH dependence.
~3~3~99 The mesh of the screen 27 is smaller than the particle size of the chemical so that only dissolved chemical in solution form may pass therethrough.
The breather cell 21 is provided with a relatively small aperture 29 in the upper wall 25 thereof which will permit water from the tank to trickle into the cell and to fill same and also to act as a breather when consumption takes place by the withdrawing of the chemical solution as will hereinafter be described. ~his water then passes through the screen 27 dissolving the chemical into a solution where the process of osmosis takes place in both cells 20 and 21. This is a reaction of saturation taking place in the container and equalizing the dissolved solution throughout both container cells.
A solution feed tube 30 which may or may not act as a syphon, consists preferably of plastic tubing, and is sealably engaged throu~h a small aperture 31 in the upper wall of the breather cell 21 and extends downwardly to adjacent the base wall 24 as clearly shown in Figure 2.
A venturi tube 31A of plastic, is engaged in series with exis~ing filler tube 14 as at 32, and 37 with the other end 33 of the filler tube engaging within the open end of the overflow pipe 15 in a conventional manner. Although the two portions of the tubes are shown spaced apart in Figure 2 for clarity, they ara urged together over venturi tube 31A once ~3~3Z9~
inserted.
The diameter of the venturi tube 31A is slightly smaller than the diameter of the filler tube 14 so that it may slide within the two pieces as clearly shown in Figure 2, in sealing relationship. The smaller diameter provides for a speeding up of the water when passing through this tube in the direction of arrow 34.
The feed tube 30 is of a relatively small diameter compared to the venturi tube 31A and it engages through an aperture 35A within the wall of the filler tube to which it is sealably engaged and then extends axially centrally and parallel through the venturi tube 31A also clearly shown in Figure 2. It will be noted that this feed tube extends to closely adjacent the outlet end of the venturi tube 31A.
Passage of the speeding water through the venturi tube induces a suction action at the near end of tube 31A
thus drawing out ~ solution of water and dissolved chemical from the breather cell 21, through the feed tube 30. This initiates a syphoning action or, alternatively maintains the suction effect.
In operation, and while the tan~ is static and full of water to the level 16, the water dissolves the chemical in cell 20 and then passes into the breather cell 21 by osmosis as hereinbefore described.
When the tank is flushed, the water level in the tank ~3~32~
falls until the tank is empty at which time the shut-off valve (not illustrated) closes and the tank commences to refill. Part of the rsfilling action is to allow a small quantity of water to pass through the filling tube 14 into the overflow pipe 15, in order to replace the water seal within the bowl (not illustrated). As this water passes under pressure through the filler tube 14, it enters the venturi tube 31A and the venturi action transfers or syphons the solution from the breather cell 21 into the water tube 14 and thus provides the necessary sanitizin~ and/or disinfecting agent in the bowl as well as providing adequate water for a proper seal.
In conclusion it should be noted that there are two conventional types of toilet bowls. In the first type, all of the water from the tank flows into the toilet bowl via the rim of the bowl and this includes the water going into the overflow pipe.
However, in the second conventional type of bowl, there is an inlet hole in the bottom of the bowl ~3~32~39 which allows a portion of the water from the tank to come into the bowl during the flushing action. The remainder of the water flows into the rim of ~he bowl. The water that i~ diverted into the overflow pipe, comes through the small inlet hole.
The first type of toilet bowl is preferable for use with the present invention due to the fact that there is only one entrance to the bowl from the tank so that all of the water must flow under the rim of the bowl.
When the water from the tank is flushed~ all of the water goes under the rim of bowl thus giving the opportunity for the chemical solution to be distributed all around the rim of the bowl at the time the flushing action comes to an end and before the filling cycle terminates. The chemical solution is thus thoroug~ly disinfecting the bowl as the solution is trickling into the bowl from the rim thereof and thîs continues until the filling cycle is completed.
However in the second type, and in order for the;dlspenser to function more effect1vely, a small round perforation 2gA is provided in one of the side walls of the breather cell so that theiuser may push out the portion of the wall covering this perforation, when same is requlred.
,~ .
.
:~3~?3;~:9~
When this perforation is opened by pushing in the portion covering same, a concentration of solution may ~rickle into the toilet tank when ~he flushing action takes place. Aæ the water level decends into the tank, the solùtion trickles into the tank until such time as the level of solution reaches the lowest portion of the perforation. For the rest of the cycle, the solution goes into the overflow pipe and directly into the toilet bowl.
This perforation should be approximately 3/4 of an inch to 1 inch below the top of the breather cell upper wall.
Since various modifications can be made to my invention as hereinabove described, and many apparently widely dif~erent em~odiments o~ same made within the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only ,and not in a limiting sense.
