Abstract

A filterwell cartridge holder having a face for compressible engaging pleats on a water filter cartridge and a further face holding a dispensing cartridge thereon in a position to release dispersants into a filterwell containing a water filter cartridge.

First claim

We claim:

1. A filterwell dispensing cartridge holder engageable with a vertical extending water filter cartridge with the filterwell dispensing cartridge holder comprising:
a panel having an arcuate face abuttable against a set of pleats of the vertical extending water filter cartridge with a portion of said panel limiting upward axial displacement of the filterwell dispensing cartridge holder and a further portion of said panel limiting downward displacement of the filterwell dispensing cartridge holder;
a pair of arms extending from said panel with said pair of arms compressively engageable with the vertically extending water filter cartridge to maintain the filterwell dispensing cartridge holder proximate the water filter cartridge;
a first dispensing cartridge holder on said panel for supporting a dispensing cartridge in a first dispensing position; and
a second dispensing cartridge holder for supporting a second dispensing cartridge thereon in a second dispensing condition.

2. The filterwell dispensing cartridge holder of claim 1 including a rib on said panel with said rib positionable in the set of pleats of the water filter cartridge to limit upward axial displacement of the filterwell dispensing cartridge holder.

3. The filterwell dispensing cartridge holder of claim 1 including a first water port in said panel with said first water port located below a dispensing end of the first dispensing cartridge supported thereon and a second water port in said panel with said second water port located below a dispensing end of the second dispensing cartridge supported thereon.

4. The filterwell dispensing cartridge holder of claim 1 wherein each of the pair of arms include hinges thereon for folding each of the pair of arms.

5. The filterwell dispensing cartridge holder of claim 1 including a first set of lateral extensions on a front face of the cartridge holder to support the first dispensing cartridge below a water line in a filterwell and a second set of lateral extensions on the front face of the cartridge holder to support the second dispensing cartridge below the water line in the filterwell.

6. The filterwell dispensing cartridge holder of claim 1 wherein the first cartridge holder and the second cartridge holder cantilever outward from a front face of the panel.

7. The filterwell dispensing cartridge holder of claim 1 wherein each of the arms of the pair of arms include water ports therein to allow water to flow into the water filter cartridge through the water ports.

8. The filterwell dispensing cartridge holder of claim 1 including a handhold for grasping the dispensing cartridge holder when removing the dispensing cartridge holder from engagement with the vertically extending water filter cartridge.

9. The filterwell dispensing cartridge holder of claim 1 where the arcuate face has a first radius of curvature and an outer edge of the pleats on the water filter cartridge have a second radius of curvature with the first radius of curvature and the second radius of curvature substantially equal.

10. The filterwell dispensing cartridge holder of claim 1 wherein each of the pair of arms include a tapered end.

11. The filterwell dispensing cartridge holder of claim 1 wherein the first dispensing cartridge holder includes an arcuate extension having a base and an arcuate flange for engaging a cylindrical dispensing cartridge thereon.

12. A filterwell dispensing cartridge holder engageable with a vertical extending cylindrical water filter cartridge located in a filterwell of a hot tub or spa with the dispensing cartridge holder comprising:
an elongated panel having an arcuate face mateable along a peripheral length of the vertical extending cylindrical water filter cartridge with the elongated panel having a water filter cartridge facing side and a dispensing cartridge support side;
a toe extending from a bottom end of the elongated panel to limit downward displacement of the dispensing cartridge holder;
a lip extending from a top end of the elongated panel to limit upward displacement of said dispensing cartridge holder;
a rib extending from the arcuate panel for maintaining the orientation of the dispensing cartridge holder with respect to the vertical extending cylindrical water filter cartridge;
a first arcuate arm extending from a first side of the elongated panel with the first arcuate arm having a hinge for folding a portion of the first arcuate arm inward for transporting or outward for filterwell use;
a second arcuate arm extending from a further side of the panel with the second arcuate arm having a hinge for folding the second arcuate arm inward for transporting or outward for filterwell use with the first arcuate arm and the second arcuate arm coacting to hold the cartridge dispenser holder proximate the vertical extending water filter cartridge;
a first set of resilient dispensing cartridge engaging arms extending radially outward from said arcuate panel for supporting a first dispensing cartridge in a below water condition;
a second set of resilient dispensing cartridge engaging arms extending radially outward from said arcuate panel for supporting a second dispensing cartridge in a below water condition; and
an arcuate lip located on a top end of the panel to limit upward displacement of the dispensing cartridge holder.

13. The filterwell dispensing cartridge holder of claim 12 wherein the first arcuate arm and the second arcuate arm each include a water port therein.

14. The filterwell dispensing cartridge holder of claim 12 including at least one water port located in said elongated panel to allow water to flow under a dispensing cartridge located in the dispensing cartridge holder and into a set of pleats of the filter cartridge.

15. The filterwell dispensing cartridge holder of claim 12 wherein each of the cartridge engaging arms include water ports therein to allow water to flow through the cartridge engaging arms and into a set of pleats of the water filter cartridge supporting the dispensing cartridge holder.

16. The filterwell dispensing cartridge holder of claim 12 wherein a diametrical dimension formed between the first arcuate arm and the second arcuate arm is sufficiently small so as to form an interference fit with a set of pleats on the water filter cartridge to maintain the dispensing cartridge holder proximate the water filter cartridge.

17. The filterwell dispensing cartridge holder of claim 12 wherein the first arcuate arm and the second arcuate arm each having a surface mateable with a set of pleats on a water filter cartridge.

18. The filterwell dispensing cartridge holder of claim 12 wherein the elongated panel comprises acrylonitrile butadiene styrene (ABS).

19. The filterwell dispensing cartridge holder of claim 12 wherein the arcuate face is a concave arcuate face.

20. The filterwell dispensing cartridge holder of claim 12 wherein the first set of resilient cartridge engaging arms and the second set of resilient cartridge engaging arms each have adjoining faces located at an angle of less than 90 degrees so that the adjoining faces engageable with an end of a dispensing cartridge to support the dispensing cartridge thereon.

21. A filterwell dispensing cartridge holder engageable with a water filter cartridge in a filterwell with the filterwell dispensing cartridge holder comprising:
a panel having a face abuttable against a set of pleats of the water filter cartridge;
a pair of arms extending from said panel with said pair of arms com
