Abstract

A cartridge carrier having a skeleton housing with a cartridge cradle for supporting a cartridge dispenser therein and a connector on the skeleton housing for supporting a further dispensing cartridge outside of the skeleton housing.

Claims (29)

1. An inline cartridge carrier comprising:

a skeleton housing having a top end and a bottom end with a cartridge cradle therebetween, the cartridge cradle sufficiently large to hold at least one cartridge dispenser therein;

a cartridge connector in the cartridge cradle, the cartridge connector comprising a key for engaging a mating keyway in a cartridge dispenser while preventing engagement of a cartridge dispenser without a mating keyway; and

a further connector located on the bottom end of the skeleton housing for engaging an end of a further cartridge dispenser to support the further cartridge dispenser outside of the cartridge cradle,

wherein the further connector comprises a further key, the further key comprising a geometrical shape cantileverly extending from the bottom end of the skeleton housing.

2. The inline cartridge carrier of claim 1 wherein the cartridge connector comprises a bayonet connector.

3. The inline cartridge carrier of claim 1 wherein the cartridge connector comprises a first set of mateable threads of a first diameter and the further cartridge connector comprises a second set of mateable threads of a second diameter.

4. The inline cartridge carrier of claim 1 comprising a first cartridge dispenser and a second cartridge dispenser, wherein the cartridge cradle supports the first cartridge dispenser and the further connector engages the second cartridge dispenser, the cartridge cradle and the further connector holding the first cartridge dispenser and the second cartridge dispenser in axial alignment.

5. The inline cartridge carrier of claim 1 wherein the cartridge connector in the cartridge cradle comprises an annular extension extendable into a keyway in a cartridge dispenser to prevent insertion of a cartridge dispenser without a keyway therein.

6. The inline cartridge carrier of claim 1 wherein the cartridge connector in the cartridge cradle is an annular extension and the further connector is a male connector.

7. The inline cartridge carrier of claim 1 wherein the geometrical shape is a four-pointed star.

8. The inline cartridge carrier of claim 1 including a handle on the top end of the skeleton housing for inserting or removing the inline cartridge carrier into or from a well in a hot tub.

9. The inline cartridge carrier of claim 1 wherein the cartridge connector comprises an annular member.

10. The inline cartridge carrier of claim 1 wherein the further connector located on the bottom end of the skeleton housing comprises a male thread.

11. The inline cartridge carrier of claim 1 wherein the geometrical shape comprises a triangular shape.

12. A cartridge carrier comprising:

a skeleton housing having a top end and a bottom end with a cartridge cradle therebetween, the cartridge cradle sufficiently large to hold at least one cartridge dispenser therein; and

a cartridge connector located on an end of the skeleton housing with the cartridge connector engageable with a further cartridge dispenser to support the further cartridge dispenser outside of the cartridge cradle,

wherein the cartridge connector has a geometric shape mateable to a geometric shape on the further cartridge dispenser.

13. The cartridge carrier of claim 12 including a key within the skeleton housing for preventing insertion of a cartridge dispenser without a mating keyway.

14. The cartridge carrier of claim 12 comprising a further cartridge dispenser, wherein the skeleton housing has a central axis and the cartridge connector supports the further cartridge dispenser along the central axis.

15. The cartridge carrier of claim 14 wherein the cartridge connector and the further cartridge dispenser are color coded.

16. The cartridge carrier of claim 12 including a handle on the top end of the skeleton housing for placement or removal of the cartridge carrier into or from a well, a cartridge dispenser located within the cartridge cradle, and a further cartridge dispenser secured to the bottom end of the skeleton housing.

17. The cartridge carrier of claim 12 wherein the cartridge connector comprises a male thread.

18. An inline cartridge carrier comprising:

a skeleton housing having a top end and a bottom end with a cartridge cradle therebetween, the cartridge cradle sufficiently large to hold at least one cartridge dispenser therein;

a cartridge connector in the cartridge cradle, the cartridge connector comprising a key for engaging a mating keyway in a cartridge dispenser while preventing engagement of a cartridge dispenser without a mating keyway; and

a further connector located on the bottom end of the skeleton housing for engaging an end of a further cartridge dispenser to support the further cartridge dispenser outside of the cartridge cradle,

wherein the further connector is an extension located along an axis of the inline cartridge carrier with the extension having a male thread thereon.
