United States Patent 3,177,502 LIQUID DISPENSING DEVICES Roland J. Meunier, 1049 Lebanon Hill, Southbridge, Mass. Filed Jan. 15, 1962, Ser. No. 166,339 19 Claims. (Cl. 4-228) This application is a continuation in part 'of my patent application, S.N. 859,321, filed December 14, 1959, since abandoned.

My invention relates to liquid dispensing devices and has particular reference to the provision of a liquid dis pensing device adapted primarily for use with flush toilets or the like.

The principal object of the invention is to provide an exceedingly simple, inexpensive and positively functioning liquid dispensing device adapted to be associated with the tank of a flust toilet or the like and which will function automatically, in response to certain changes in the level of the water in said tank, to discharge a controlled amount of the liquid into said water.

Another object is to provide a device of the above character having a container formed with a support having longitudinally disposed liquid dispensing grooves or tracks therein adapted to be positioned internally of the tank of a flush toilet with the lower ends of said container being located at a predetermined distance above the low level which the water assumes in the tank as the result of flushing whereby a controlled amount of liquid in said container, at said low level, will be automatically discharged under the combined action of capillary attraction and gravity and will thereafter be automatically shut off in response to the rise of the water in said tank subsequent to said flushing.

Another object is to provide a dispensing device of the above character wherein the liquid discharged thereby may be a disinfectant, deodorant, cleansing agent or the like or combinations thereof which as the result of each successive flushing a certain amount of the water having the liquid therein will flow into and remain in the bowl of the toilet while the device simultaneously discharges a predetermined amount of liquid into the water being replaced in the tank.

Another object is to provide a device of the above character wherein the liquid container may be easily replaced or refilled when empty.

Briefly, I use a liquid dispensing device embodying a bottlelike container and a bar-like support therefor of material preferably of one of the known plastics which is resistant to corrosion and chemical attack supported so as to extend vertically from said bottle into the water in the tank in which it is positioned so that it will be permanently wetted by said Water at all levels thereof. The barlike member has an outer or external holding means such as a thread or flexible collar rings to hold the bottle. The barlike member further comprises two or more grooves or tracks extending longitudinally of the major portion thereof having a controlled width and length through which liquid in the bottle, due to said wetting, may flow under the combined action of capillary attraction and gravity so as to intermingle with the water in the tank when the water reaches its minimum level as the result of flushing the toilet and which action will cease when the water in the toilet reaches its maximum level after said flushing.

Other objects and advantages of the invention will become apparent from the following description taken in connection with the accompanying drawings wherein:

It is commonly known that toilets located in club rooms, rest rooms in gas stations, etc., and even in homes particularly in instances when the toilets are not frequently used that the tank, as well as the bowl of such toilets, become stained or coated with a slimy film which is difficult to remove. This is also true of the working parts of the toilet with the result that in many instances such working parts deteriorate or become clogged and inoperable.

The present invention, therefore, is directed to the provision of a device adapted to be supported in association with the tank of flush toilets or the like embodying a container having therein a liquid disinfectant, deodorant, cleansing agent or combinations thereof and which responds to changes in the level of the water in said tank whereby a controlled amount of the liquid in the container will be directed into the water in the tank by the last individual who flushes the tank and will simultaneously direct a given amount of water containing said liquid into the bowl of the toilet so as to remain therein subsequent to said flushing.

This arrangement has been found to provide a means for protecting not only the interior of the tank and its working parts but also the bowl from being similiarly coated and stained.

Referring more particularly to the drawings wherein like characters of reference designate like parts through out the various views, the device embodying the invention comprises a container 10 having a liquid 11 therein which may either be a disinfectant, deodorant, cleansing agent or combinations thereof adapted to be supported in the tank of a flush toilet or the like by a suitable support 13. The container 10 may be in the form of a conventional bottle or the like, having an open ended threaded neck portion 14 onto which a cap 15, such as shown in FIG. 1, is threaded to seal the liquid in the container. To further insure the sealing or retaining of the liquid in the container the open end of the threaded neck may be provided with a film 16 of glassine or the like which is secured in overlying relation with said open end.

The support 13 is in the form of a bar 17 of corrosion resistant material such as a rigid polyvinyl chloride material containing a suitable antacid such as lead carbonextent of discharge.

hesive forces are reduced. It is evident that if the width ate and containing an anti-oxidant such as carbon black to render it resistant to chemical attack and aging. The bar may also be formed of linear polyethylene or cellulose I wardly of such openings.

areas, applicant has found that a constant flow will take acetate butyrate which may also have such an antacid and anti-oxidant therein to render the bar resistant to'chemical attack and to prevent aging thereof. The bar 17 has an exterior relatively coarse thread 18 formed longitudinally thereof and has spaced longitudinally disposed grooves 19 therein. The grooves are controlled in length so as to terminate at a location 20 which will be a predetermined distance above the base 21 of the tankof a flush toilet or the like. The lower endof the bar is preferably provided witha reduced portion 22 having a flangelike head 23 thereon to which the neck 24 of a suction cup 25 of suitable resilient material such as rubber or the likemay be attached, it being understood that, the neck 24 is provided with connection openings which are adapted to receive the neck portion 22 and the enlarged end 23 therein so as to be resiliently gripped by said neck place even under different degrees of temperature.

With a liquid such as commonly known Lestoil,. the provision of two grooves 19 in the support of bar 17 each having a cross-sectionalxarea of substantially /s" produces very adequate resultsin temperaturesranging from 44 to 80. I

'Instead of using only two grooves 19, additional grooves diagrammatically illustrated by the dash lines 31 in FIG. 4 mightbe'utilized. In this instance the areas of the grooves would be substantially: half those of the groove 19, thatis,- all of the

respective grooves

19 and 31 would have a cross-sectional area of approximately A vIt has been found from actual use that when the fluid 11 starts to be drawn downwardly of one of the grooves 19 prior to the other by the combined action of capillary attraction and gravity the other of said grooves will permit air to pass upwardly thereofinto the liquid 11 therebypermittin'g the liquid to flow outwardly of the container dependingthrough which of said grooves the fluid first starts to flow.

such that it will normally be immersed in the Water in the tank in the flush toilet, not shown,and below the up- 1 per level of the water as illustrated by the line 27. The

container 10 is, therefore, forced downwardly in' the water of the tank .to a locationwherein the film 16 will be penetrated by the point end 26' and a coarse thread 28 formed internally of said neck 14 may be threadedly connected to the 'coarsethread 18 of the bar or support '17. v

In FIGS. 5 and 6 there is shown a slight modification of the invention wherein the top of the support or bar 17 is provided with a transverse opening 32 through which a' wire 33 is extended and frictionally held- The wire 33 'is bentjdownwardly, as shown in FIG. 5, so as-to profrom flowing outwardly of the container as it is jbeing j initially assembled with the support of bar 17.

the lower level 30 establishes the extent of discharge of' the fluid into the water into the tank and may restrict or increase said discharge by raising or lowering the end 29 f relative to the lower level 30 which. the water assumes in the toilet tank subsequent to the flushing thereof.

It is pointed out:that the cross sectional areas of thegrooves 19 are. also controlled dimensionally-in accordance with the extent of discharge of liquid desired. The

function of the grooves 19 is to cause the liquidto be discharged throughs'aid groovesby the combined function of capillaryattraction and ,gravity with the capillary attraction resulting from the grooves -19 being initially wetted'both by the water in the tank and the fluid in the container.

Since the adhesion of the liquid to the solid surface if walls of the grooves produces an adhesive force, it is evident that the amount of this adhesive force depends upon the width and length of the grooves. This adhesive force, in turn, is a determining. factor in controlling the As the walls arewetted, the adthe grooves'19 being wetted by the water causing an initial capillary attraction for drawing the liquid 11 out of the container the liquid, under varying conditions,, would not of necessity flow suffieiently'freely inorder to discharge the amount desired into the water in'the tank.

in spacedrelation-with the walls of the-grooves. This "is' .to further assistin insuring that the fluid 11 will flow downwardly under the combined action of capillary attraction and'gravity'. In this i'nstance, the depending portions 34 of the wire 33 will be initially wetted, as stated The containerlO is adjusted, as shown in FIG. 3, so .35,

positionedinternally of each of said grooves as defined above.

* It is to beunderstood. that when liquids 11 of different viscosity are' used, the diametrical areas of the slots will be varied accordingly or thev amount of slots may be varied accordingly. 7

' Referring now to FIG. 7,-there is shown a container '10 filled with a suitable liquid 11. The verticalibar or rod 13' has a'plurality of vertically extending grooves 19 as shown belowinyFIG. 8 and has relatively wide-spaced threading 36. 'Grooves 19 extend" up to a top end of 7 bar 13 to communicate with the liquid 11.

The neck of container 10'has an external threading 35'the internal purpose of which neck defines the discharge f opening. An adapter or coupling37'is provided-to allow It has been found that when openings were provided inthe' 1 end of the container and through which the fluid was 7 adapted to flow merely by the action of gravity, the grav-L ity was not sufficient to ,overcomethe surface tension of to communicate with grooves trol the rate of discharge. 5

rod 13"10 fit within the discharge opening. Adapter 37 comprises a base .38 having a width greater than the discharge opening in an upper body which fits within the discharge opening. The body of the adapter has sides 39, the upper part of which tapers gradually to provide an, easy'fit within the discharge opening. There are 'provided'a plurality of longitudinally extending grooves or slits 40 which'may be rotated as adapter 37 is turned 19 and thereby further con- 'Theadapter 37 has an internal threading 43 which cooperates with threading 36 of rod 13. The base 38 is formed with a relatively rigid insert 42 having the internal thread .43. Insert 42 fits within base 38 and is joined to; the walls thereof shown at 41. The material forming the walls 41 as well as the body may be rela- Therefore, through, the provision of longitudinal grooves-of controlled cross-sectional tively flexible to provide a degree of flexibility when inserted in the discharge opening.

It is to be recognized that the surface tension provided by the walls of the grooves 19 impedes the flow of the liquid. Further, the diameter or width of the grooves 19 determines the shape of the liquid flowing therein which provides a further degree of retardation. As the fluid or droplet as the case may be reaches the bottom of grooves 19, it will flow on to the surface 19 in which case the effective surface tension will be substantially reduced. While at the position shown at 19', the fluid 11 may more easily intermingle with the water in the tank. In the drawing shown in FIG. 7, it is to be recognized that the length of the groove extending below adapter 37 may be varied.

In the embodiment shown at FIG. 10, there is provided a rod 13 having the same longitudinal grooves 19. The upper surface has a tight threading shown at 45. An adapter or coupling unit 46 is provided having a base and upwardly extending walls 48 which have an internal threading to fit the external threading 35 and container 10. The base of the adapter has an internal threading 47 which cooperates with the threading 45 of rod 13".

In the embodiment of FIG. 11, the container is similarly provided with the external thread 35 at its discharge opening. An adapter or plug 51 having a base which covers the discharge opening is provided with an internal recess or bore to receive rod 13". Rod 13 has the same longitudinal grooves 19. However, in this embodiment, rod 13 is provided with a plurality of spaced apart collars or retaining rings 50 which may be generally flexible. The width of these collars is greater than the width of the internal bore of the adapter 51. Therefore, the adapter 51 may sit on one of the rings as shown at as. To indicate the flexibility of these rings, one of them 52 is shown in an exaggerated distorted position. If desired, only one retaining ring as shown at 50 may be provided. In other respects, rod 13" and container ill are similar to those previously described.

The characteristics of the flush toilet with which the device of the present invention may be used is as dia grammatically illustrated in applicants co-pending application, Serial No. 790,267, filed January 30, 1959, since abandoned.

While certain arrangements or combination of parts are shown and described by way of illustration of the invention, it is to be understood that many variations or modifications may be made without departing from the spirit of the invention as expressed in the accompanying claims, the real essence of the invention being that of providing an arrangement whereby the fluid may be drawn from the container by the combined action of capillary attraction and gravity and with the wetting of the parts so as to bring about the above results. The said arrangements and combination of parts shown and described are, therefore, merely illustrative of the invention and are not to be interpreted in a limiting sense.
