- FIG. 1 there is shown a first embodiment of a waterless urinal 10 according to the invention.
- the urinal 10 has an interior bowl surface 12 with an outlet opening 14 .
- FIG. 1 also shows a first embodiment of a removable cartridge assembly 16 according to the invention.
- the cartridge assembly 16 is mounted within the opening 14 and connected to mains sewerage by pipes 18 .
- the cartridge assembly 16 is best shown in FIGS. 2 to 7 and has a generally cylindrical plastic body 20 .
- the body 20 has external threads 22 on one end and a distally diverging taper 24 on the other end.
- the taper 24 terminates in a flange 26 which is adapted, upon installation, to seal against the outlet opening 14 in the urinal's interior surface 12 .
- the cartridge assembly 16 is inserted through the outlet opening 14 from the urinal's interior and is retained by tightening a nut 28 along the thread 22 until it engages with the lower edge 14 a of the outlet opening 14 .
- a rubber one-way valve 30 is positioned within the body 20 by an external flange 34 thereon locating against an internal shoulder 36 on the interior of the body 20 .
- the valve 30 is of the type previously described and has flexible walls 38 (see FIG. 7 ) which expand and separate to allow urine to pass downwardly therethrough and then automatically close to the position shown in FIG. 7 to prevent odor from passing upwardly therethrough.
- the top of the valve 30 has four locating arms 40 which are adapted to snap engage with a plastic cup 42 .
- the cup 42 is adapted to receive a scent or deodorizing block 44 therein.

- the operation of the tabs 48 make the cartridge assembly 16 resistant to unauthorized disassembly (e.g. by vandals), as will be described in more detail below, making it suitable for public applications.
- the cap 46 is positioned so as to leave about a 9 mm high gap 52 between the bottom of the cap 46 and the top of the flange 26 .
- urine flows along the bowl surface 12 into the gap 52 , through the cartridge assembly 16 and through the valve 32 to mains sewerage via the pipes 18 .
- the gap 52 also allows pleasant odors from the scent block 44 to pass into the room in which the urinal 10 is installed.
- the cartridge and urinal described above have several advantages. Firstly, the cartridge is very easy to install and use. It is also very easy to install, remove, or replace the scent block 44 , and without requiring disassembly of the cartridge 16 from the urinal 10 . Secondly, the mounting of the slightly convexly curved (almost flat) cap 46 only slightly protruding from the adjacent interior surface 12 of the urinal 10 provides an aesthetically pleasing, unobtrusive visual appearance to the cartridge assembly 14 and the urinal 10 , as the cap appears to follow the contours of the bowl interior. This is particularly apparent when viewed from almost directly above, which is the point of view of most users of the urinal 10 .
- FIGS. 16 to 20 show an embodiment of a cartridge assembly removal and installation of a tool 60 according to the installation.
- the tool 60 has a handle 61 , a first end 62 , adapted for selective engagement with the cap 56 , and a second end 64 , adapted for selective engagement with the scent block 44 .
- the first end 62 of the tool 60 has a fixed jaw 66 and a movable jaw 68 .
- the movable jaw 68 is connected to button 70 and, as best shown in FIG. 18 , depression of the button 70 towards the tool body 61 , as indicated by arrow 72 , causes the movable jaw 68 to move away from the tool body 61 , as indicated by arrow 74 , to increase the distance between the jaws 66 and 68 .
- the tool 60 also includes a spring 76 which biases the jaws towards the (minimum opening) position shown in FIGS. 16 to 20 in the absence of pressure on the button 70 .
- a user depresses the button 70 to widen the gap between the jaws 66 , 68 . This allows the jaws 66 , 68 to be passed over the top of the cap 46 and into the gap 42 .
- the jaws 66 , 68 move inwardly and contact the tabs 48 and move the tabs 48 inwardly and away from engagement in the openings 50 , which frees the cap 46 from engagement with the cup 42 .
- the cap 46 is also gripped by the jaws 66 , 68 and can then be lifted free of the cartridge assembly 16 .
- a similar procedure to that described above can also be used to grip and remove the cup 42 from the cartridge assembly 16 .
- a reverse of the above procedures can be used to reinstall a fresh cup 42 and scent block 44 and also reinstall the cap 16 .
- the second end 64 of the tool 60 includes an end formation 76 which is adapted to engage with the interior of the flange 34 associated with the one-way valve 30 .
- the end formation 76 also includes a gripping part 78 , which may be slid in the direction of double-headed arrow 80 , relative to an internal formation 82 .
- the gripping part 78 is slid away from the first end 62 .
- the end formation 76 is then pressed into engagement with the one-way valve 30 .
- Withdrawing the tool 60 away from the cartridge assembly 16 results in the removal of the valve 30 from the cartridge assembly 16 .
- the gripping part 78 is then slid back towards the first end 62 which causes the internal formation 82 to abut the valve 30 and force it out of engagement with the end formation 76 , for disposal.
- a reverse of this procedure can be used to install a replacement one-way valve 30 into the cartridge assembly 16 .
- the tool 60 allows the cap 56 , cup 42 , scent block 44 and one-way valve 30 to be removed and/or replaced in the cartridge assembly 16 without requiring human contact with these, or any other, components of the cartridge assembly 16 . This is advantageous from a hygiene perspective.
- FIGS. 8 to 11 show a second embodiment of a removable cartridge assembly 16 ′ according to the invention.
- the cartridge assembly of 16 ′ is similar to that shown in FIGS. 1 to 7 and like reference numerals are used to denote like features with the first embodiment.
- the cap 46 of the cartridge assembly 16 ′ is formed from Vitreous China and does not snap engage with the cup 42 like the first embodiment. Instead, the cap 46 merely sits on top of the cup 42 and is retained in the position shown in the drawings by its own mass. As a result, the cartridge assembly 16 is suited for home or other non-public applications.
- FIGS. 12 to 15 show a third embodiment of a removable cartridge assembly 16 ′′ according to the invention.
- the cartridge assembly 16 ′′ is similar to that shown in FIGS. 1 to 7 and like reference numerals are used to denote like features with the first embodiment.
- the cartridge assembly 16 ′′ has a cap 46 which is releasably connected to the cup 42 by the tabs 48 which engage with corresponding openings 50 in the underside of the cap 46 .
- the cartridge assembly 16 ′′ also requires use of the tool 60 for removal of the cap 56 and access to the scent block 44 and is also therefore vandal resistant and thus suited for use in public applications.

FIG. 18 is a cross-sectional side view of the tool shown inFIG. 16 along the line 18-18; -
FIG. 19 is a top view of the tool shown inFIG. 16 ; and -
FIG. 20 is a bottom view of the tool shown inFIG. 16 . - Referring firstly to
FIG. 1 , there is shown a first embodiment of a waterless urinal 10 according to the invention. The urinal 10 has aninterior bowl surface 12 with an outlet opening 14.FIG. 1 also shows a first embodiment of aremovable cartridge assembly 16 according to the invention. Thecartridge assembly 16 is mounted within theopening 14 and connected to mains sewerage bypipes 18. - The
cartridge assembly 16 is best shown in FIGS. 2 to 7 and has a generally cylindricalplastic body 20. Thebody 20 hasexternal threads 22 on one end and a distally divergingtaper 24 on the other end. Thetaper 24 terminates in aflange 26 which is adapted, upon installation, to seal against the outlet opening 14 in the urinal'sinterior surface 12. Thecartridge assembly 16 is inserted through the outlet opening 14 from the urinal's interior and is retained by tightening anut 28 along thethread 22 until it engages with thelower edge 14 a of theoutlet opening 14. - A rubber one-
way valve 30 is positioned within thebody 20 by anexternal flange 34 thereon locating against aninternal shoulder 36 on the interior of thebody 20. Thevalve 30 is of the type previously described and has flexible walls 38 (seeFIG. 7 ) which expand and separate to allow urine to pass downwardly therethrough and then automatically close to the position shown inFIG. 7 to prevent odor from passing upwardly therethrough. - The top of the
valve 30 has four locatingarms 40 which are adapted to snap engage with aplastic cup 42. Thecup 42 is adapted to receive a scent or deodorizingblock 44 therein. A shallowly curved,plastic cap 46 is releasably connected to thecup 42 bytabs 48 on thecup 42 which engage withcorresponding openings 50 in thecap 46. Thecap 46 can be removed from thecup 42 by pressing thetabs 48 inwardly away from theopenings 50. The operation of thetabs 48 make thecartridge assembly 16 resistant to unauthorized disassembly (e.g. by vandals), as will be described in more detail below, making it suitable for public applications. - The
cap 46 is positioned so as to leave about a 9 mmhigh gap 52 between the bottom of thecap 46 and the top of theflange 26. In use, urine flows along thebowl surface 12 into thegap 52, through thecartridge assembly 16 and through the valve 32 to mains sewerage via thepipes 18. Thegap 52 also allows pleasant odors from thescent block 44 to pass into the room in which theurinal 10 is installed. - The cartridge and urinal described above have several advantages. Firstly, the cartridge is very easy to install and use. It is also very easy to install, remove, or replace the
scent block 44, and without requiring disassembly of thecartridge 16 from theurinal 10. Secondly, the mounting of the slightly convexly curved (almost flat)cap 46 only slightly protruding from the adjacentinterior surface 12 of theurinal 10 provides an aesthetically pleasing, unobtrusive visual appearance to thecartridge assembly 14 and theurinal 10, as the cap appears to follow the contours of the bowl interior. This is particularly apparent when viewed from almost directly above, which is the point of view of most users of theurinal 10. - FIGS. 16 to 20 show an embodiment of a cartridge assembly removal and installation of a
tool 60 according to the installation. Thetool 60 has ahandle 61, afirst end 62, adapted for selective engagement with the cap 56, and asecond end 64, adapted for selective engagement with thescent block 44. - The
first end 62 of thetool 60 has a fixedjaw 66 and amovable jaw 68. Themovable jaw 68 is connected tobutton 70 and, as best shown inFIG. 18 , depression of thebutton 70 towards thetool body 61, as indicated byarrow 72, causes themovable jaw 68 to move away from thetool body 61, as indicated byarrow 74, to increase the distance between thejaws tool 60 also includes aspring 76 which biases the jaws towards the (minimum opening) position shown in FIGS. 16 to 20 in the absence of pressure on thebutton 70. - In use, a user depresses the
button 70 to widen the gap between thejaws jaws cap 46 and into thegap 42. When pressure on thebutton 70 is released, thejaws tabs 48 and move thetabs 48 inwardly and away from engagement in theopenings 50, which frees thecap 46 from engagement with thecup 42. Thecap 46 is also gripped by thejaws cartridge assembly 16. - A similar procedure to that described above can also be used to grip and remove the
cup 42 from thecartridge assembly 16. - A reverse of the above procedures can be used to reinstall a
fresh cup 42 andscent block 44 and also reinstall thecap 16. - The
second end 64 of thetool 60 includes anend formation 76 which is adapted to engage with the interior of theflange 34 associated with the one-way valve 30. Theend formation 76 also includes agripping part 78, which may be slid in the direction of double-headedarrow 80, relative to aninternal formation 82. - In use, the
gripping part 78 is slid away from thefirst end 62. Theend formation 76 is then pressed into engagement with the one-way valve 30. Withdrawing thetool 60 away from thecartridge assembly 16 results in the removal of thevalve 30 from thecartridge assembly 16. Thegripping part 78 is then slid back towards thefirst end 62 which causes theinternal formation 82 to abut thevalve 30 and force it out of engagement with theend formation 76, for disposal. - A reverse of this procedure can be used to install a replacement one-
way valve 30 into thecartridge assembly 16. - It should be noted that the
tool 60 allows the cap 56,cup 42,scent block 44 and one-way valve 30 to be removed and/or replaced in thecartridge assembly 16 without requiring human contact with these, or any other, components of thecartridge assembly 16. This is advantageous from a hygiene perspective. - FIGS. 8 to 11 show a second embodiment of a
removable cartridge assembly 16′ according to the invention. The cartridge assembly of 16′ is similar to that shown in FIGS. 1 to 7 and like reference numerals are used to denote like features with the first embodiment. However, thecap 46 of thecartridge assembly 16′ is formed from Vitreous China and does not snap engage with thecup 42 like the first embodiment. Instead, thecap 46 merely sits on top of thecup 42 and is retained in the position shown in the drawings by its own mass. As a result, thecartridge assembly 16 is suited for home or other non-public applications. - FIGS. 12 to 15 show a third embodiment of a
removable cartridge assembly 16″ according to the invention. Thecartridge assembly 16″ is similar to that shown in FIGS. 1 to 7 and like reference numerals are used to denote like features with the first embodiment. Thecartridge assembly 16″ has acap 46 which is releasably connected to thecup 42 by thetabs 48 which engage withcorresponding openings 50 in the underside of thecap 46. As a result, and similar to the first embodiment ofcartridge assembly 16, thecartridge assembly 16″ also requires use of thetool 60 for removal of the cap 56 and access to thescent block 44 and is also therefore vandal resistant and thus suited for use in public applications. - Although the present invention has been described with reference to specific examples, it will be appreciated by those skilled in the art that the invention may be embodied in many other forms.
