  • a compartment 58, containing wastewater treatment tablets 60, has an entry 62 for receipt of wastewater 64 and an outlet 66 couplable to an external drain (not shown) .
  • Intermediate portion 54/54M (see also FIGS. 16-22M) comprises (as best seen in FIGS. 16, 16A and 17) a two-level platform 68 having upper and lower surfaces 70 and 72.
  • Upper and lower surfaces 70 and 72 are bifurcated into two sections (70a, 70b and 72a, 72b) on opposed sides of the intermediate portion.
  • the intersections of lower sections 72a and 72b with wall segments 84 and 85, with the upper part of baffle weir 90 and the opposite wall of intermediate portion 54 adjacent a passage 924 form the upper side boundaries of an opening 74.
  • Upper sections 70a and 70b, with wall segment 94 and the upper part of baffle weir 90 form the upper side boundaries of an opening 76.
  • Intermediate portion 54 also includes upper and lower parts 78 and 80 (see also FIG. 19) which are joined respectively to upper and lower surfaces 70 and 72 and extend upwardly and downwardly therefrom.
  • Upper part 78 includes an upstanding enclosure 82 of cylindrical shape, which terminates in an upper open end 83a.
  • Lower part 80 is terminated in a lower open end 83b which constitutes a portion of the bottom terminus of intermediate portion 54; other portions will be presently described.
  • Intermediate portion ' lower part 80 includes a compartmentalizing wall structure comprising a plurality of wall segments 84, 85, 86, 88, 90, 92 and 94 which divide the compartmentalizing wall structure into a wastewater-receiving compartment 96, and a wastewater outlet-to-drain compartment 98. Two of the segments form weirs 90 and 92.
  • first weir or segment 90 is secured to and between a parallel pair of wall segments 85 and 84 and acts as a baffle which divides wastewater- receiving compartment 96 into a primary or wastewater inlet chamber 106 and a wastewater inlet-to-outlet chamber 108 (e.g., also see FIGS. 3, 3A, and 16A) and forms a separation therebetween.
  • First weir or baffle 90 slopes downwardly to a terminal end 110 in (primary) wastewater inlet chamber 106 and away from wastewater inlet-to-outlet chamber 108 for directing the wastewater away from the wastewater inlet-to-outlet chamber. Because first weir 90 is sloped (see, for example, FIGS.
  • the views of chambers 106 and 108 have different appearances as depicted in FIGS. 16 and 18; that is, their entries and exits in these two figures are respectively larger or smaller, depending upon whether the view is from the top or the bottom of the intermediate portion.
  • Terminal end 110 is rounded to militate against debris, especially hair, from adhering thereto.
  • second weir or segment 92 is secured to and between « parallel pair of wall segments 86 and 88, which segments are divided respectively into half segments 86a, 86b and 88a, 88b.
  • Second weir 92 forms another one of the wall segments and acts as a baffle between the wastewater inlet-to-outlet chamber 108 and wastewater outlet-to-drain compartment 98.
  • Second weir or baffle 92 has an inwardly sloped, ridged and hook-shaped rounded end 112 (see FIGS. 3, 3A, 4, 4M, 16, 16A, 20 and 21) which is sloped downwardly from wall half segment pair 86a and 88a towards its bottom 113 (see FIG. 21) to form a ridge.
  • Rounded end 112 is further draped downwardly to its tip 920.
  • the second weir extends into wastewater outlet-to-drain compartment 98 to provide a terminal overhang at tip 920 that produces a waterfall-like effect, that is, the wastewater is directed generally away from wall half segments 86a, 88a by the ridge configuration and from segment 94 and second weir/segment 92 by its hook-shaped configuration. Accordingly, the object is to direct the flow from contact, to the extent possible, with the segments and half segments that define the walls of wastewater outlet-to-drain compartment 98. This waterfall-like effect also militates against the adherence of hair and other debris to the hook-shaped rounded end.
  • Cartridge 50 opens to its exterior through an entry 122 (e.g., FIG. 3) that communicates with (primary) wastewater inlet chamber 106 through a throat 158. It is an important feature of the present invention that the breadth of throat 158 be considerably smaller that the breadth of chamber 106.
  • a pair of fins 926 and 928 (FIGS. 16, 16A and 24) (see FIG. 61) and an opening 930 (FIGS. 16 and 24, but not in FIG. 61) are formed on and in intermediate portion 54 within a secondary reservoir 220 (e.g., as shown in FIGS. 3B and 61) . Fins 926 and 928 are positioned adjacent to the opening (see FIG.
  • Some of the suction exerted on the contents of the secondary reservoir via sealant protection recovery channel 222 is directed on the lower depth fluids therein as directed thereto by a pair of fins 948 that extend downwardly from channel 222 into the lower depths of reservoir 220 (see FIGS. 3B, 10, 11, 12, 13 and 23A) . Because opening 194 is aligned with the end of channel 222 (see FIG. 3B) , the flow of water pushes any sealant by the channel away. Therefore, the suction draws wastewater from the lower depths and from the dumped water, rather than the sealant floating on the surface of the wastewater. Thus, the sealant in the secondary reservoir is substantially preserved, and is available to flow back into throat 158 after the dumping results have subsided.
  • Lower opening 936 (FIGS. 3, 4, 16, 16A, and 18) and opening 936x (FIG. 61) , as also communicating with the secondary reservoir, acts as a sealant and wastewater outlet into wastewater- receiving compartment 96 and its (primary) wastewater inlet chamber 106. Opening 936/936x permits an easier transfer of urine back into the primary flow path by reducing fluid pressure, a vacuum, when dumping occurs and also provides a further flow path than provided by fins 948.
  • lower opening 936/936x encourages water from bucket dumps that enter into secondary reservoir 220 to flow through the secondary reservoir and exit through opening 936/936x, rather than flowing out of this reservoir through sealant protection recovery channel 222 and orifice 162, thereby avoiding the drawing in of sealant with it into the primary flow path extending through throat 158.
  • opening 936/936x is made sufficiently large as not to restrict fluid flow, and thus to encourage all fluid entering through vent openings 124 to drain through opening 936/936x. Further, the positioning of opening 936/936x is sufficiently low so that the water dumping, which would agitate the sealant bubbles, would not be sufficient as to cause the bubbles to float down to the level of opening 936 and, therefore, otherwise pass therethrough.
  • a seat 114 is positioned on the underside of intermediate portion platform lower surface 72 adjacent compartmentalizing wall structure segment 88 for enabling the seating and attachment of treatment tablet compartment 58 to intermediate portion platform 68 (see FIG. 16) .
  • a passageway 116 is positioned in the intermediate portion platform at a height above hook-shaped rounded end 112 of second weir 92 for coupling wastewater inlet-to-outlet chamber 108 to treatment tablet compartment 58 for supply of some of the wastewater to treatment tablets 60.

  • top portion 52 having upper and lower surfaces 118 and 120 and with wastewater and vent openings 122 and 124 therethrough, is secured to intermediate portion 54/54M at its upper end terminus 83a (e.g., FIGS. 3 and 3B, 16 and 16A) .
  • the top portion is provided with an annular slot 126 in its circumference and an O-ring 128 (FIGS. 2 and 61) is positionable therein so that cartridge 50/50M/50x may be inserted within a urinal and held in a fluid-tight engagement therewith.
  • Openings 122 comprise a wastewater entry for passage of the wastewater into (primary) wastewater inlet chamber 106 of the intermediate portion wastewater-receiving compartment.
  • Openings 124 which are spaced outwardly from wastewater entry opening 122 and are positioned closer to annular O-ring slot 126, comprise a plurality of air vent openings, with passageways 130 and vent holes 131 (see FIGS. 3B, ⁇ - 7-9, 61 and 62) extending downwardly therefrom, from top portion lower surface 120. Openings 124 also provide a means by which a tool may be inserted therein for the purpose of placing and removing the cartridge into and from a urinal as, for example, described in PCT International Publication Number WO 2005/071171 Al, published 04 August 2005. [0085] As best shown in FIGS. 7-9 (see also FIGS 4 and 4A), top portion 52 is completed with an air vent-assisting guiding structure 132, which includes a pair of tubular extensions 914 and 916.

  • the outer circumference of the sealant reservoir is circumscribed by cylindrical enclosure 82 of intermediate portion 54 and its inner donut-shaped hole is formed by throat 158 of wastewater entry passageway 152 of the chamber divider.
  • a sealant reservoir fill hole 191 (see FIGS. 16, 16A, 22, 22M, 23 and 24) in upper level 70a of platform 68 provides access to the sealant reservoir for filling it with sealant 238.
  • Sealant reservoir fill hole 191 (see FIGS. 22, 22M, 23, 24 and 36-38) includes a tubular lip 938 so that it can be plugged up by a plug 940. Once sealant reservoir 190 is filled with sealant, plug 940 remains in place, but is removable in the event that the reservoir needs to be replenished.
  • a plurality of air vent passageways 192 with openings 194 therethrough extend upwardly from chamber divider platform 142 , and are coupled to top portion passageways 130.
  • Passageways 130 and 192 effect air vents comprising openings 124, 131 and 194 from secondary reservoir 220 to top portion air vent openings 124 and to the exterior of cartridge 50.
  • These passageways also can form alternate paths for urine or other fluids should the necessity for such paths arise.
  • bottom portion 56 comprises a cap part 196 and extension parts 198 and 199.
  • the cap part is secured to and forms a fluid-tight closure with intermediate portion 54 at its lower terminal end 83b.
  • Extension part 198 is secured to wastewater outlet-to-drain compartment 98, and includes a flow director 200 for aiding in the flow of wastewater to the external drain.
  • Extension part 199 forms a base for the bottom of secondary reservoir 220 as best shown in FIG. 66.
  • secondary chamber 220 is positioned adjacent to (primary) wastewater inlet chamber 106 and below sealant reservoir 190, and communicates therewith through a sealant protection recovery channel 222 (second wastewater entry passageway) (see FIG. 3B) and thence to orifice 162 in throat 158.
  • Secondary reservoir 220 is normally disposed to receive sealant after water has been inserted into the cartridge and, thereafter, sealant from sealant reservoir 190 has been supplied to wastewater- receiving compartment 96.
  • a sealing plug assembly 230 comprising a plug 232 secured to an end of a pull tape 234 is employed.
  • Plug 232 is shaped so as to enable it to fit within orifice 160, as illustrated in FIGS. 3, 3A, 3C, 3D, 10, 13 and 13M.
  • Pull tape 234 is threaded through and extended out of top portion entry 122 for grasping by an operator and consequent removal of plug 232 when cartridge 50 is readied for use in the urinal.
  • a seal may be pasted or otherwise adhered onto the wall of throat 158 over orifice 160 in place of plug 232; however, the adhesive or other affixing means must be capable of resisting its possibility of being loosened, such as by the sealant, and in keeping the orifice closed off until such time as the seal is to be removed.
  • Sealant reservoir 190 is then filled with sealant through its fill hole 191 which, thereafter, is sealed by sealing plug 940.
  • a maintenance person, or the like then prepares the cartridges for use. Water is poured through entry 122 and into bottom portion 56, as shown in FIG. 4. The level of dispersed water 236 first contacts the bottom of first weir 90, effectively separating wastewater-receiving compartment 96 into (primary) wastewater inlet chamber 106 and wastewater inlet-to- outlet chamber 108 and continues to fill the cartridge until the water level approximately reaches throat 158.
  • sealant seal tape 234 grasps sealant seal tape 234 and pulls it and plug 232 from sealant reservoir opening or orifice 160.
  • This procedure enables sealant 238 to be released from sealant reservoir 190 and to flow through filter 176 and orifice limiter 172, along downwardly sloping cap 180 and its U-shaped channel 182 into throat 158, as depicted by arrow-headed lines 244 in FIGS. 4 and 4A.
  • An open air path from the throat, including opening 168 avoids any creation of negative pressure from being built up in the sealant reservoir resulting from the flow of the sealant into the throat, which would otherwise cause at least a slowing of sealant flow.
  • the air flow is depicted by arrow-headed lines 246 as shown in FIGS. 4 and 4A.
  • Rounded terminal end 110 of first weir 90 and hook-shaped rounded end 112 of second weir 92 are positioned so as to provide a complimentary matching therebetween to enable the volume of (primary) wastewater inlet chamber 106 to be substantially the same as wastewater inlet-to-outlet chamber 108 and, thus, to ameliorate the problems of negative pressure differential across the cartridge trap.
  • the volume of wastewater outlet-to-drain compartment 98 and that in (primary) wastewater inlet chamber 106 and wastewater inlet-to-outlet chamber 108 are such as to avoid siphoning; that is, the wastewater outlet-to-drain compartment 98 is sufficiently large to prevent siphoning of liquid within the cartridge if a negative pressure differential exists across the cartridge trap or if any bucket of water is dumped into the cartridge.
  • the amount of sealant, as released from the sealant reservoir and floating on the dispersed water prior to urination is beyond what is needed for modicum 242 to exist in throat 158.
  • the reason for orifice 162 and opening 936 is to use secondary reservoir 220 as a backup tank into which sealant and wastewater can be flowed.
  • Orifice 162 allows a slow flow between the liquids in throat 158 and the secondary reservoir, as aided by sealant protection recovery channel 222.
  • orifice 162 can be used alone without opening 936, it is preferred to use both orifices together.
  • the main purpose of the secondary reservoir is to avoid the deleterious effects of when a bucket of water is dumped into cartridge 50. When dumping occurs, sealant in the first wastewater inlet chamber 106 can be flushed out of that chamber and into the drain through outlet-to-drain compartment 98, but this flushing has a minimal effect on the sealant in the secondary reservoir.
  • cartridge 5Ox includes wastewater-receiving compartment 96 and wastewater outlet-to-drain compartment 98, and further utilizes a water reservoir 100.
  • the water reservoir has an opening 102 communicating with wastewater- receiving compartment 94 and is sealable by a seal 104, which becomes a normally sealed water fill hole 105, after the water reservoir has been filled.
  • bottom portion 56 comprises a cap part 196 and extension parts 198 and 199.
  • the cap part is secured to and forms a fluid-tight closure with intermediate portion 54x at its lower terminal end 83b.
  • Extension part 198 is secured to wastewater outlet-to-drain compartment 98, and includes a flow director 200 for aiding in the flow of wastewater to the external drain.
  • Extension part 199 forms a base for support of a water reservoir 100, and includes a water fill hole 206.

Abstract

L'invention concerne une cartouche (50) destinée à être placée dans un urinoir, qui comprend une chambre (106) dotée d'une ouverture (122) recevant le liquide de décharge (64) (par exemple, l'urine), un minimum (242) d'agent d'étanchéité (238) capable de flotter sur le liquide de décharge dans la chambre et agissant à titre de barrière contre les odeurs qui peuvent émaner du liquide de décharge, un réservoir (190) d'agent d'étanchéité couplé à la chambre contenant un approvisionnement d'agent d'étanchéité, et un distributeur d'agent d'étanchéité à chemin fermé, afin de distribuer l'agent d'étanchéité du réservoir d'agent d'étanchéité à la chambre et maintenir un très petite quantité d'agent d'étanchéité au-dessus du liquide de décharge. Le distributeur d'agent d'étanchéité comprend un capuchon 180 doté d'un canal 182 en forme de U, d'une ouverture 170 et d'un orifice pénétrant dans une gorge (158) dans laquelle le très petite quantité d'agent d'étanchéité flotte. Un évent d'air (168, 916, 914) empêche l'accumulation d'aspiration dans le réservoir principal. Un réservoir secondaire (220) peut être couplé au réservoir d'agent d'étanchéité pour retenir un matériau d'étanchéité supplémentaire, en plus de tout liquide de décharge qui pourrait accompagner l'agent d'étanchéité pour conserver l'agent d'étanchéité, et est particulièrement utile pour éviter les effets nuisibles du liquide qui est déversé dans la cartouche (50), en particulier un matériau d'étanchéité qui est évacué dans un drain par le biais du compartiment (98) de sortie vers le drain, l'évacuation ayant un effet minimal sur l'agent d'étanchéité dans le réservoir secondaire. Si on le désire, un réservoir d'eau (100) peut être logé dans la cartouche.
