Abstract

A filter well mountable dispenser holder securable within a hot tub filter well with the dispenser holder supporting replaceable dispersant containing dispensing cartridges positionable within a circulating flow of water through the filter well to thereby release dispersants therefrom without preventing the circulating flow of water from passing through the filter media proximate the dispensing cartridges.

First claim

We claim:

1. An underwater dispenser holder comprising: a base having a first dispensing cartridge top support and a second dispensing cartridge top support; a finger grip extending from a topside of said base; a first cartridge post extending from a bottom side of said base with the first cartridge post having a cartridge support thereon; a second cartridge post extending from a bottom side of said base with the second cartridge post having a cartridge support thereon; and a set of filter cap engaging latches.

2. The underwater dispenser holder of claim 1 wherein said first dispensing cartridge top support comprises a first yoke and said second dispensing cartridge top support comprising a second yoke.

3. The underwater dispenser holder of claim 2 wherein the first yoke includes at least two resilient extensions for snap-in engagement with a first dispensing cartridge and the second yoke includes at least two resilient extensions for snap-in engagement with a second dispensing cartridge with each of the resilient extension having a first shoulder for engaging a first filter cartridge end cap and a second shoulder for engaging a second filter cartridge end cap.

4. The underwater dispenser holder of claim 1 including a three-sided dispensing cartridge mounted thereon with at least two of the sides have a concave exterior surface.

5. The underwater dispenser holder of claim 1 wherein the dispenser holder is supported on a first end and a second end of the filter cartridge with the dispenser holder having at least one dispensing cartridge supporting socket for removably supporting a dispensing cartridge containing a dispersant therein below a water line and spaced from a filter media; and a pair of radial offset arms located on opposing ends of dispenser holder with each of the arms having a mounting slot for securement to a filter cartridge hub located at each of the ends of the filter cartridge.

6. The underwater dispenser holder of claim 5 including an end adapter releasably attachable to the mounting slot on each of the arms, said end adapter having at least one locking protrusion for engaging the dispenser holder; and a dispensing cartridge supporting socket including at least one radial protrusion mateable with a latch pocket located on an exterior surface of the dispensing cartridge to secure a dispensing cartridge thereto.

7. The underwater dispenser holder of claim 5 including an end adapter releasably attachable to each of the mounting slot, the end adapter enabling the attached mounting slot to secure to a male hub of the filter cartridge in a snap-in manner, the end adapter having at least one locking protrusion and each of the arms of the dispenser holder having at least one corresponding adapter receiving slot for engagement with the locking protrusion to secure the end adapter to the mounting slot.

8. The underwater dispenser holder of claim 5 including a dispensing cartridge having an oval-shaped body for twist in installation to a dispensing cartridge socket on the dispenser holder, the dispensing cartridge having at least one vent hole located on a top end of the cartridge and a stand-off extending partially into an interior of the dispensing cartridge to prevent material blockage of an outlet of the dispensing cartridge.

9. The underwater dispenser holder of claim 5 wherein the dispenser holder includes a pair of arms located on opposing ends of the dispenser holder with each of the arms having a mounting slot for securement to a corresponding filter cartridge mount port located proximal each of the ends of the filter cartridge in a snap-in manner.

10. The underwater dispenser holder of claim 5 including an end adapter releasably attachable to each of the mounting slot, the end adapter enabling the attached mounting slot to secure to a male hub of the filter cartridge in a snap on manner, the end adapter having at least one locking protrusion and each of the arms of the dispenser holder having at least one corresponding adapter receiving slot for engagement with the locking protrusion to secure the end adapter to the mounting slot.

11. The underwater dispenser holder of claim 5 wherein the dispenser cartridge supporting socket includes at least one alignment member mateable with a latch pocket located on an exterior surface of a dispenser cartridge to secure the dispenser cartridge to the dispenser cartridge supporting socket.

12. The underwater dispenser holder of claim 5 wherein the dispenser holder supports the least one dispensing cartridge between the filter cartridge and the water line with the dispenser holder including a pair of arms located on opposing ends of the dispenser holder with each of the arms having a mounting slot for mounting the dispenser holder to a filter cartridge mount ports in a snap-in manner.

13. The underwater dispenser holder of claim 5 including an end adapter releasably attachable an arm in a snap-in manner with the end adapter having at least one radial latch and each of the arms of the dispenser holder having at least one corresponding adapter slot with a latch for engagement with the radial latch to secure the end adapter to an arm of the dispenser holder through rotation of the end adapter.

14. The underwater dispenser holder of claim 5 wherein the dispenser holder includes at least one dispensing cartridge supporting socket comprising a first cantilevered resilient extension and a second resilient extension for rotationally securing a dispensing cartridge to the dispenser holder.

15. The underwater dispenser holder of claim 14 wherein the first cantilevered resilient extension includes a radial protrusion having a first angled end and a second angled end for twist removal of the dispensing cartridge from the dispensing cartridge supporting socket.
