Abstract

ABSTRACT OF THE DISCLOSURE
A toilet flush water colorizer is provided including a container adapted for receiving therein a flush water -coloring block. The container has at least one entry opening for admitting flush water thereinto, and out-let means for the discharge of colored flush water from the container. The colorizer further comprises suspending means for suspending the container at the inside of a toilet bowl, and a diluting chamber in the interior of the container adapted for collecting drops of color concentrate dripping off a block after each flushing. The outlet means are located in the bottom of the diluting chamber. By this construction, no significant "after dripping" of the flush water drops of increased colorant concentration, and hence no sub-stantial staining of the sidewall of the toilet bowl will occur.

Description

This invention relates to a toilet flush water colorizer of the type which includes a contalner adapted for receiving therein a flush water-coloring block and having at least one entry opening for admitting flush water thereinto, and outlet means for the discharge of colored flush water from the container.
Toilet flush water colorizers of the above-described type are known, for instance, from British patent specification ~o. 1,057,865 to J. Goddard & Sons ~imited, wherein a receptacle containing an erodable coloring block, i.e. a block which is slowly dissolved and/or disintegrated from the outside inwardly by the flush water, is placed or hung into the cistern for the flush water of a toilet.
The coloring block contains as primary ingredient a soluble color-ing materialJ e.g. a dyestuff or pigment, a blue coloring of the flush water in the toilet bowl being preferrad. Of course, such blocks or sticks are also known to contain disinfectants or deodorants, as well as cleaning agents. When, after actuation of the flushing device of the toilet re-peatedly over a prolonged period of time, e.g. for a month or more, the flush water leaves the cistern uncolored, this will indicate that the coloring block has been consumed, its coloring agent being exhausted.
Replacement of the exhausted block by a new one requires that the user can take off the lid of the cistern, put in the new block and then fasten the lid back in place. ~owever, increasingly, such cisterns are being manu-factured of thermoplastic resin material and after mounting the discharge valve means therein~ the lid is fastened on the cistern by means of glueing or thermic welding, thus making replacement impossible.
As the effectiveness of active ingredients, in particular of deodorants, of such blocks ~lich have been -~ 2 --, ~3~'7 discharged from the block into the flush water in a toilet cistern is only very weak ~nd hence unsatisfactory~ blocks or sticks containing such ingreai-ents have for some time been suspended in a small slotted container, e.g. a small elongated basket, at the inner sidewall of a toilet bowl, as has been described in French patent No~ 1,602,063 to Madison Chemical Corporation (see also ~nited States patent No. 3,529,309 to Seyrnour Leavitt et al, in particular Fig. 3).
Ho~ever, if a toilet bowl cleansing block of this type would con-tain a colorLng agent, e.g. a blue dyestuf~, besides the deodorant, disin-fectant and cleansing agents now conventionally present therein, in order tocolor the flush water in the toilet bowl, e.g. a blue color, at each flushing of the toilet, then this would ha~e the drawback, confirmed by the applicant in numerous tests, that after each flushing, when the flow of flush water has subsided, there is still an "after-dripping" of the block, i.e. drops of flush water continue for a prolonged period of time, depending on the erodi-~ility of the block, in fact often for five to ten hours or moreJ to flow down the sidewall of the toilet bowl. The concentration of colorant in these drops increases with time; thus producing a stripe of color, e.g. of blue on the sidewall which e~tends from the block container downwardly caus-ing an unclean, unesthetic aspect of the bowl. This stripe is the moredifficult to remove, the longer the "after-dripping" has lasted.
An object of a broad aspect of this invention is to provide a toilet flush water colorizer of the initially described type which can be hung in a toilet bowl in a similar manner as described supra in the case of the Leavitt cleansing block~ without substantially suffering from the above-described serious drawback of staining the internal sidewall of the toilet bowl by after-dripping of drops of increasing colorant concentration from the block after each flushing.

~3'7~'~

~ It is an object of another aspect of this invention to provide a toilet flush water colorizer of the initially described type from which di-luted colored flush water is discharged.
According to a broad aspect of this inventio~, a toilet flush water colorizer of the initially described type is provided which further comprises suspending means for suspending the container at the inside of a toilet bowl and a diluting chamber in the interior of the container adapted for collecting drops of color concentrate dripping off a block after each flushing, and wherein the outlet mealls are located in the bottom of the diluting chamber.
By an aspect of this invention, a toilet flush water colorizer is provided comprising a container adapted for receiving therein a flush water-coloring block and having at least one entry opening Eor admitting flush water thereinto and outlet means for the discharge of colored flush water from the container, the colorizer comprising: (a) suspending means for sus-pending the container at ~he inside of a toilet bowl; (b) a diluting chamber in the lower part of the interior of the container and adapted for collecting drops of color concentrate dripping off the water-coloring block after each flushlng, and (c~ supporting means in the container across the upper end of the diluting chamber and adapted for supporting a flush watèr-coloring block in the upper part of the container above the diluting chamber, the supporting means having at least one opening for permitting flush water to pass from the upper part of the container into the diluting chamber~ the container hav-ing a bottom and side walls, the side walls being closed up to the upper end o the diluting chamber; and tne outlet means being located in the bottom of the container in communication with the diluting chamber, the outlet means comprising siphoning means having a siphon passage the apex of which passage is below the upper end of the diluting chamber and below the level of the supporting means, the siphoning means being adapted for siphonlng off flush water from the diluting chamber down to a minimum sump level.

3~

In a preferred embodiment of the toi].et flush water colori~er accordin,, ~o an as?ect of this invention, the diluting cha~ber comprises (a) supporting means in the co~tainer across the upper en~ of the d-luting cha~ber ~herein and adapted for ~upporting a flush water-coloring block in the container above the diluting chamber, which supporting means have at least one opening for permltting flush water to pass from the upper part of the container into the diluting chamber, and (b) the container has a bottom and side walls, the l.atter being closed up to the upper end of the diluting chamber, and wherein (c) the outlet means are located in the bottom of the container and are siphoning means adapted for siphoning off flush water from the dilut-ing chamber down to a minimum sump level.
By one variant of this invention, the supporting means can have a plurality of openings which are narrow enough to prevent larger pieces of a colorizing bloc~ eroded by flush water from dropping into the diluting cham-ber. ~loreover, by another variant, the supporting means can comprise pro-jections from the inner sidewall of the container into the interior of the latter. By yet another variant, these supporting means can also comprise a grid or perforated plate adapted for supporting a coloring block.
By yet another variant of this invention, the siphoning means can comprise a suction tube in the lower par~ of the diluting chamber for suction-ing off the colored flush water under the hydrostatic pressure thereof which prevails in the diluting c~amber.
Preferzbly, ~y a variation thereof, the suction tube is sealingly inserted in the bottom o~ the diluting chamber and has its upper end curved whereby its upper opening is near the bottom of the diluting cha~ber.
In a most preferred embodiment, the suct-ion tube is sealingly in-serted upright in the bottom of the diluting chamber, having its upper open-ing near the upper end of the diluting chamber and its lower opening in or 3~5'7 or underneath the bottom, and in which embodiment the siphoning means further comprise a cover me~ber mounted on the bottom of the diluting chamber and having a closed upper part inside which the upper end of the suction tube opens; the cover member further has ports near or at the bottom of the dilut-ing chamber for the passage of colored flush water from the latter chamber into the interior of the cover member and onward into the suctlon tube.

~ig. 3 is a cross-sectional view of the same embodiment, in a plane indicated by III-III in Fig. 2;
Fig. 4 is a view from above of the same embodiment as shown in Figures 1 to 3, of a toilet lfush water coloriz~r being open at the top;
Fig. 5 is a cross-sectlonal view similar to that shown in Fig. 3, but having a somewhat different embodiment of the siphoning means;
Fig. 6 is a cross-sectional view of another embodiment of the toi-let flush water colorizer according to another aspect of the invention; and Fig. 7 is a perspective view of the embodiment shown in Fig. 6 seen from the front and abo~e, and having the conventional suspending clamp partially broken away.
The prefarred embodiment of the toilet flush water colorizer accord-ing to an aspect of this invention shown in Figures 1 to 4 comprises a con-tainer 1 having approximately the shape of a deep trough. The frontal wall
2, the rear wall 3 and the lateral end wall~ L~ and 5 are closed in their lower region upward to half the height of the trough, and surround, together with a bottom 6~ a diluting space or chamber 7, which latter can be filled ,,. ~
3~7~

with flush water up to a level 8, when the color:izer is hung in a toilet bowl and the flushing mechan-ism of the toilet is actuated. In the four walls 2, 3,
4 and 5, above the level 8, windows 9 are provided which are separated rom one another by ports 10. Some of these ports 10 bear on their insides dis-tancing projections 11, and as support-- 6 a -, 1~3~3'~'7 ing mea~a, carrie~ ri~s 12 project horizontally into the interior space of the container 1 at level ~. Prefera~ly, a grid or per orated plate 13 is placed on the carrier ribs 12. A coloring block or stick 1~ which is indicated S by a phantom line in Fig. 3 r~sts on the aforesaid supporting means. When a perforated plate 13 is used, the holes therein are preferably so narrow that larger pieces O:t the block which become loosene~ ~y the gradual erosion of the latter can not fall -through these holes into the diluting space 7. At its upper end lS, the container 1 is preferably open~
In the embodiments of Figures 1 to 4, a 5iphon ing device is provided in -the bottom 6 of the container 1 and comprises a cover part 16, preferably having -the shape of an in~erted cup,which sits on the inside face of the bottom 6 and has ports 17 provided in its si.dewall 16a near the bottom 6. In the bottom 6, centrally to the cover part 16, there is provided an opening 18 having a circumferential rim in which an annular groove 19 is pro-vided. A straigh~ discharge tube 20 bearing a closingflange 21 transverse to the tube axis, is pressed with the latter sealingly into the groove 1~. Preferably, flange 21 is integral with tube 20. Outlet tube 20 is thus mounted coaxially with cover part 16 and has an axial outlet duct 22. Outlet tube 20 and the interior space 23 of cover part 16, in which the outlet tube 20 projects with its upper end to near the closed roof wall 16b thereof, con stitute together a siphoning devi e by means of which colored flush water, filling the diluting space 7 maximal-ly up to level 8 , is suctioned off~ at each flushing ofthe toilet9 until the level of the liquid in space 7 has dropped again to the upper end of ports 17. In the liquid sumps 24 which remain above the bottom 6, any "after-dripping" drops of flush water of increasing colorant 3~5~

concentration are collected and diluted. However, due to the siphoning effect of the siphoning device, the pheno-menon of "after-dripping" is stron~ly reduced or even completely avoided~
In the preferred embodiment, the container 1 can be manufactured in one piece from synthetic plastics mate-rial by injection molding techniclues, whereupon the tube 20 is pressed with its flange 21 into the groove 19 of bottom opening 18, in order to assemble the colorizer.
The container is provided in a conventional manner with a clasp or eyepiece 25 in which a known Plas-tic suspending clip 26 i5 inserted, by means of which the container 1 can be attached to the inner upper sidewall of a toilet bowl below the inwardly projecting rim bead of the latter, which head may also project outwardly.
When the flushing mechanism of the toilet is actuated, flush water will flow along the underside of this upper rim bead on the inside at least of the rear wall of the toilet bowl, or, in other~ types of such bowls also from outlets at the underside of t~e rim bead about th~ entire circumferenca of the toilet bowl, with mor~ or less pressure. This causes a certain turbulënce of the flush water stream whereby always a sufficient amount of flush water DenetrateS into the container 1, dissolving ~5 or eroding colorant as well as, if present, other ingredi-ents, e.g., cleansing agents or disinfectants from the coloring block or stick, whereupon the flush water laden with such ingredients passes thro~lgh the openings.of the grid or perforated plate 13, or when the latter is miss-ing, between the carrier bars 12 into the diluting space 7 - therebelow.
Under the hydrostatic pressure of the hydro-static flush water, which co'lects in diluting spac~ 7 at 7S~

each flushing, coIored flush water will then flow throuyh the siphol~ing device constituted by cover part 16 and out-let tube 20 from container 1 in~o the toilet bowl. No significant "after-dripping" of flush water dro~s of~increased colo-rant concentration, and hence no substanti~l staining of the sidewallof the toilet bowl underneath the container 1 will occur.
In the embodiment show~ in FicJ.5, the siphoning device consists of a simple suctioning tube 30 having A
curved, dowl-wardly opening bent portion 30a, the opening o~ which i9 inside the diluting space 7 near and ahove tha bottom 6 of the latter. However, the making or assembly of this embodiment is more complicated, as the suction tube .
30 is more difficult to make from synthetic plastics ma-terial, while its assembly is similar to that of the em-bodiment of Figuresl to 4, if it is provided with anannular flange by which it can engage the annular groove 19 of central bottom opening 1~.
The embodiments shown in Figures 6 and 7 com-prise a drum-shaped container 31 which is especially suitable for being hllng in such toilet bowls in which the flush water does not emerge only at the inside of the rear wall of the toilet bowl but also underneath the circumfe-rence of the upper, inwardly projecting bowl bead~ Belo~
the level 8, the diluting space 7 and the siphoning device therein are devised analogous to that of the first embodi-ment, and in the region of the level 8, carrier bars 12 projecting into the interior of container 1 andfor a grid or perforated plate are provided as in the first embodi-ment In the upper part of container 31, t~e rear wall 33 thereof which is destined to come to lie against the sidewall of the toilet bowl, is preferably closed, while the front wall 32 has a number of slots or windows 39 se-paratPd from one another by ports 40. Spacing elements 41 _ 9 _ ` :

can be provided to project from the inside of the front walL 3~ and of th~ rear wall 33.
In its upper wall the container 31 has an elon-gated axially e~tending slot or opening 45 and bears, at the edge of the latter adjacent the rear wall 33, an up~-wardly protruding ba~fle plate 34. Also in this embodiment, a colorlng stick ~s~ rests on the supporting bars 12 or a grid or perforated plate placed on the latter, and is helcl in place by the spacing elements 41 which prevent it from resting against the wall of the container with ensuing non-uniform erosion.
A fastening clip 46 is also provided, by means of which the container 31 can be hung into a toilet bowl with the upper edge of baf~le plate 43 abutting against the underside of the upper inwardly projecting toilet bowl head in such a manner that flush water outlet ori-fices in that underside are located inwardly of baffle plate 43 toward the interior of the toilet bowl. Flush water which emerges from these orifices or otherwise streams along that bead underside is deflected by the baffle plate 43 through the axial slot 45 onto the coloring block or stick 44.
In all other aspects~ the effect of the diluting chamber 7 and of tha siphoning device oE that em~odiment is the same as in the embodiments of Figures 1 to 5.
