Abstract

A dispensing system for delivery of a dispersant from a canister containing an erodible but cakeable water dispersant wherein the cakeable water dispersant in a one piece caked condition falls to a bottom of a divergent walled canister so the water flowing through a bottom portion of the canister continues to maintain erodible contact with the dispersant as the water disperant is consumed.

First claim

We claim:

1. A dispensing system for controlled delivery of cakeable dispensable materials to a body of water comprising:
an inline dispenser having a chamber with a closed top end;
a dispensing canister having a central axis located in said chamber with said dispensing canister having an internal compartment formed by an interior sidewall that flares radially outward in a downward direction a fluid inlet fitting in the inline dispenser for directing water upward into the dispensing canister;
a fluid outlet fitting in the inline dispenser for directing water out of the dispensing canister;
a cakeable dispersant located in said dispensing canister chamber, said dispensing canister interior sidewall with the interior sidewall comprising a non interfering sidewall with a top portion of the of the non interfering sidewall having a smaller cross sectional dimension than a bottom portion of the non interfering sidewall for the cakeable dispersant located at the top portion of the dispensing canister to fall to the bottom portion of the dispensing canister; and
a single fluid inlet port located at a peripheral edge of the dispensing canister and offset from the central axis, said fluid inlet port located at a bottom of a diverging funnel shaped inlet extending outward from the bottom portion of the dispensing canister and a single fluid outlet port located at a peripheral edge of the dispensing canister and offset from the central axis with a bottom of a diverging funnel shaped outlet extending outward from the bottom portion of the dispensing canister with the fluid inlet port of the dispensing canister in fluid communication with the fluid inlet port of the inline dispenser and the fluid outlet port of the dispensing canister in fluid communication with the fluid outlet port of the inline dispenser whereby a fluid flowing through the inline dispenser can at least be partially diverted through the cakeable dispersant falling to the bottom portion of the dispensing canister.

2. The dispensing system of claim 1 wherein the canister has a frusto conical shape.

3. The dispensing system of claim 1 wherein the cakeable dissolvable dispersant comprise a mineral, a pesticide, a corrosion control chemical, a water scale treatment chemical or a chemical to control a biofilm in a water treatment system.

4. The dispensing system of claim 1 wherein a bottom fluid inlet of the canister is spaced from a bottom fluid outlet of the canister so that a fluid flowing through the canister flows past the cakeable dispersant at the bottom portion of the canister chamber.

5. The dispensing system of claim 1 wherein the sidewall of the canister is smooth.

6. The dispensing system of claim 1 wherein the cakeable dispersant comprise a cakeable dissolvable dispersant that remains in a caked condition as a portion of the cakeable dissolvable dispersant is eroded by the flow of water through the canister.

7. The dispensing system of claim 6 wherein the cakeable dissolvable dispersant has a shape that conforms to the sidewall of the canister.

8. The dispensing system of claim 7 wherein the cakeable dissolvable dispersant has a specific gravity greater than one.

9. The dispensing system of claim 8 wherein the cakeable dissolvable dispersant erodes from a bottom surface of the cakeable dissolvable dispersant while a side surface of the cakeable dissolvable dispersant maintains in contact with an interior sidewall of the canister.

10. The dispensing system of claim 9 wherein the interior sidewall of the canister is in contact with a side surface of the cakeable dissolvable dispersant.

11. The dispensing system of claim 10 wherein the cakeable dissolvable dispersant has a weight that causes the cakeable dissolvable dispersant to migrate toward a bottom of the canister as a bottom portion of the cakeable dissolvable dispersant is eroded by water flowing through the bottom of the canister.

12. A dispensing canister for maintaining a correct delivery rate even though a dispersant therein may form a dispersant bridge within the dispensing canister comprising;
a housing having a chamber therein with the chamber defined by a closed top member and a bottom member;
a flared non interfering sidewall joining the top member to the bottom member with the sidewall diverging from the top member to the bottom member, said non interfering sidewall allowing a caked dispensing material which bridges from side to side of the canister, to fall into a flow path through the bottom of the canister where the caked dispensing material is contacted by water flowing through the bottom of the canister; and
a diverging bottom inlet and a converging bottom outlet in the bottom member of the dispensing canister for directing a fluid into an underside of a caked dispensing material in the chamber whereby the caked dispensing material in an undissolved state falls toward the bottom of the chamber as material is eroded from the underside of the caked dispensing material.

13. A dispensing system for controlled delivery of cakeable dispensable materials or non-cakeable materials that have difficulty in falling to a bottom of a dispenser where the materials can be dispensed into a body of water comprising:
an inline dispenser having a canister chamber;
a fluid inlet in the inline dispenser for directing water upward into the canister chamber;
a fluid outlet in the inline dispenser for directing water downward out of the canister chamber;
a canister located in said canister chamber, said canister having a flared, non-interfering sidewall with a top portion of the canister having a smaller cross sectional dimension than the bottom portion of the canister;
a cakeable or a non-cakeable dissolvable dispersant located in said canister chamber;
a fluid inlet and a fluid outlet on the canister comprising a screen or open bottom portion of the canister whereby a fluid flowing through the inline dispenser valve can at least be partially diverted proximate the cakeable or the non-cakeable dispersant in the canister chamber.

14. A dispensing container for maintaining a stable dispersant delivery rate as a bridgeable dispersant contained therein is incrementally decreased through a fluid flowing through the container comprising:
a housing having a top end and a bottom end with an internal downwardly diverging non interfering sidewall extending from said top end to said bottom end to form a downwardly diverging dispersant compartment therein;
a fluid dissolvable bridgeable dispersant that adheres to itself in the presence of a fluid to form a dispersant bridge located within the dispersant compartment with the dispersant extending laterally across said downwardly diverging dispersant compartment and in contact with the internal downwardly diverging non-interfering sidewall but without adhering to the sidewall so that a weight of the dispersant is sufficient to gravity feed the dispersant to a bottom of the dispensing container whether the dispersant is in either a bridged condition or a non bridged condition;
a peripheral fluid inlet passage located at the bottom of the dispenser container with said fluid inlet passage directing the fluid into the fluid dissolvable bridgeable dispersant in the dispersant compartment to thereby incrementally carry dispersant away from a bottom end of the dispersant compartment; and
a peripheral fluid outlet passage located in said housing for transporting the fluid with the dispersant therein out of the dispenser container.

15. The dispensing container of claim 14 wherein the internal downwardly diverging non-interfering sidewall forming the dispersant comp
