A diverter according to claim 1 in which one of said float and said shell have a magnet secured thereto and the other of said flat and said shell incorporate a ferromagnetic part therein whereby, when said float is moved towards said shell, said float and said shell are magnetically latched together thereby to evidence the existence of any such upper wall collected urine.

4. In a urine cartridge having an upper wall and an opening therein for receipt of urine and for entry of the urine into the cartridge, a diverter for avoiding direct access of the urine to the opening, comprising:

a shell placeable on the upper wall of the cartridge and over the opening therein;

a spacer spacing said shell from the upper wall to permit urine to flow into the upper wall opening of the cartridge;

said shell including an essentially fluid-obstructing upper surface bounded by a periphery which is spaced from the upper wall of the cartridge by said spacer, whereby said essentially fluid-obstructing upper surface is configured to direct the urine towards said periphery and thence onto the cartridge upper wall for entry into the upper wall opening, and said essentially fluid-obstructing upper surface of said shell includes an opening therein;

a protective cap in said fluid-obstructing upper surface of said shell and closing the opening therein from fluid flow therein, said protective cap including a viewing window; and

a float moveable towards and away from the cartridge upper wall and floatable upon any urine collected on the cartridge upper wall, said float having a viewable surface which is viewable through said protective cap viewing window when said float is caused to float upon urine collected on the cartridge upper wall and move upwards to said viewing window of said protective cap and thereby to evidence the existence of such upper wall collected urine.

5. A diverter according to claim 4 further including:

a tablet disposed as an agent which is capable of providing any such function as a deodorant and a sanitizing agent; and

a retainer engageable with said shell for supporting said tablet.

6. A diverter according to claim 5 in which said retainer comprises an open-structured cup for supporting said tablet and for exposing said tablet to any urine collected in the upper wall.

7. A diverter according to claim 6 in which said open-structured cup comprises an outer ring-like member, an inner ring-like member, and a plurality of spokes connecting said inner and outer ring-like members, said inner ring-like member having a passage therein for enabling contact of said float with any urine collected in the upper wall.

8. A diverter according to claim 7 in which said shell at its periphery includes latches for engagement with said outer ring-like member and for securing said open-structured cup to said shell.

9. A diverter according to claim 4 further comprising:

a tubular housing having an end secured to said shell upper surface and extending therefrom, and being positioned coaxially with the shell upper surface opening for housing said float; and

a spacing mechanism positioned between said float and said tubular housing for centering and guiding said float within said housing.

10. A diverter according to claim 9 in which said spacing mechanism comprises a plurality of ribs spaced from one another and forming a minimum contact between said float and said housing.

11. A diverter according to claim 9 further including a support on the inside of said tubular housing for supporting said float and for limiting travel thereof towards the shell upper surface.

12. A diverter according to claim 9 in which said tubular housing includes a second end spaced from said end which secures said tubular housing to said shell upper surface, and a latching mechanism at said second end engageable with the cartridge upper wall opening for securing said diverter to the cartridge.

13. A diverter according to claim 4 further comprising:

a tubular housing secured to and extending from said shell upper surface and positioned coaxially with the shell upper surface opening for housing said float; and

a plurality of ribs formed on said float and dimensioned to provide a minimal frictional and guiding contact with said housing for centering said float within said housing and for providing a plurality of fluid passages therebetween.

14. A diverter according to claim 13 in which said float includes a concave-shaped bottom surface facing the urine cartridge upper wall, and said ribs extend beyond said concave-shaped bottom surface to form lips and thereby to encourage flow of any urine from said float and to discourage residual urine deposits thereon.

15. A diverter according to claim 14 further comprising a ridge surrounding the shell upper surface opening for encouraging flow of urine towards said shell periphery.

16. A diverter according to claim 15 in which said protective cap has a mushroom-shaped configuration comprising:

an enlarged head;

a relatively smaller hollow stem extending from said enlarged head through the shell upper surface opening for receipt in said hollow stem of a portion of said float; and

an indentation formed beneath said enlarged head adjacent said hollow stem for discouraging flow of urine onto said stem.

17. In a urine cartridge having an upper wall and an opening therein for receipt of urine and for entry of the urine into the cartridge, a diverter for avoiding direct access of the urine to the opening, comprising:

a shell placeable on the upper wall of the cartridge and over the opening therein;

a spacer spacing said shell from the upper wall to permit urine to flow into the upper wall opening of the cartridge;

a float moveable towards and away from the cartridge upper wall and floatable upon any urine collected on the cartridge upper wall;

an indicator associated with said float and disposed to evidence the existence of any such upper wall collected urine;

a tablet disposed as an agent which is capable of providing any such function as a deodorant and a sanitizing agent;

a retainer engageable with said shell for supporting said tablet in said shell, and comprising an open-structured cup for supporting said tablet and for exposing said tablet to any urine collected in the upper wall; and

said open-structured cup comprising an outer ring-like member, an inner ring-like member, and a plurality of spokes connecting said inner and outer ring-like members, said inner ring-like member having a passage therein for enabling contact of said float with any urine collected in the upper wall.

18. A diverter according to claim 17 in which said shell at its periphery includes latches for engagement with said outer ring-like member and for securing said open-structured cup to said shell.

19. In a urine cartridge having an upper wall and an opening therein for receipt of urine and for entry of the urine into the cartridge, a diverter for avoiding direct access of the urine to the opening, comprising:

a shell placeable on the upper wall of the cartridge and over the opening therein;

a spacer spacing said shell from the upper wall to permit urine to flow into the upper wall opening of the cartridge;

an attachment facilitator including at least one opening medium in said cartridge upper wall; and

a coupling mechanism secured to said shell and disposed to engage said upper wall opening for enabling said shell to be coupled to said upper wall and, thus, to said cartridge, said coupling mechanism latches for latching said latches into said upper wall opening facilitator.

20. A diverter according to claim 19 in which said opening medium comprises slots for mutual latching with said latches.

21. In a urine cartridge having an upper wall and an opening therein for receipt of urine and for entry of the urine into the cartridge, the improvement comprising a float moveable towards and away from the cartridge upper wall and floatable upon any urine collected on the cartridge upper wall, said float having a viewable surface which is viewable when said float is caused to float upon urine collected on the cartridge upper wall and thereby to evidence the existence of such upper wall collected urine.

22. A urine cartridge according to claim 21 further comprising a protective cap including a viewing window placed over said float for enabling viewing of said float viewable surface.
