Definitions
- floating dispensers for delivering a dispersant or dispersants to a body of water
- the dispensers contain a halogen and float upright in a body of water until the halogen is consumed whereupon the dispenser flops on its side.
- the dispenser sinks to the bottom of the pool and remains there until the dispersant has been consumed at which time the dispenser floats to the top of the pool to alert the operator to replace the dispenser.
- a nondissolvable weight such as a marble, is included in the dispenser with the dispenser floating on its side when the dispersant is consumed. As the dispenser floats on its side the marble rolls along the interior of the dispenser and transfers the weigh to the end of the dispenser causing to dispenser to invert after the dispersant is consumed.
- a floating dispenser having an external float or an internal float for supporting a cartridge or cartridges for floatingly delivering a dispersant or dispersants to a body of water with the floating dispenser having cartridges rotationally positionable with respect to one another to control the rate of dispensing while the dispenser floats in an upright condition.
- the floating dispenser changes its flotation orientation in response to consumption of the dispersant or dispersants in the a cartridge to thereby provide a visual alert to replace a spent cartridge with a fresh cartridge which can be done by removing the spent cartridge from the dispenser and attaching the fresh cartridge to the floating dispenser. While the dispensers shown herein are suitable for use in pools spas and the like other uses may be found by those in the water treatment field.
- inventions described herein permit changing the dispensing nature of the system from a multiple dispensing system to a single dispensing system without changing the floating characteristics of the floating dispensers through replacement of a dispersant in one of the cartridges with an inert or ballast material that has no effect on the water characteristics.

- FIG. 1 shows a perspective view of a spherical floating status-indicating dispenser 10 for use in pools, spas or other bodies of water that require water treatment such as killing harmful organisms in the water or affecting other characteristics of the water by releasing a dispersant therein.
- Dispenser 10 comprises two hemispherical cartridges 12 and 13 , which are floatingly supported by a floatation ring 11 extending around the outer circumferential region of cartridges 12 and 13 .
- the first hemispherical dispensing cartridge or cap 13 having a circular base and a pole region 13 a and the second hemispherical dispenser similarly, having a hemispherical cartridge or cap 12 having a pole region 12 a.
- FIG. 1 shows a perspective view of a spherical floating status-indicating dispenser 10 for use in pools, spas or other bodies of water that require water treatment such as killing harmful organisms in the water or affecting other characteristics of the water by releasing a dispersant therein.
- FIG. 1A shows a perspective view of the hemispherical cartridge 13 revealing a circular base 14 having a pie shaped section removed therefrom and a central extension 19 extending from a central axis of the dispensing cartridge 12 while FIG. 1B shows a side view of the hemispherical cartridge 13 .
- FIG. 1 , FIG. 1A and FIG. 1B show that the first hemispherical cap or cartridge 13 contains a chamber 30 a and a set of fluid openings 32 for ingress and egress of water to chamber, 30 a, which for example, may contain a batch of minerals 9 for delivering metal ions into a body of water. Examples of minerals usable in dispensers may be found in U.S. Pat. No. 6,500,334, which is hereby incorporated by reference. Chamber 30 a may be used to hold other materials including inert items, which are used for ballast in the dispenser 10 when the dispenser is changed from a dual dispensing mode to a single dispensing mode.
- extension 19 Located on the underside of cap 13 is the elongated extension 19 and a tapered head 19 a that can be used to engage and rotationally secure hemispherical cartridge 13 to hemispherical cartridge 12 through a base-to-base relationship that permits one to rotate cartridge 12 with respect to cartridge 13 to select an appropriate dispensing rate.
- extension 19 holds the base 15 of cartridge 12 and base 14 of cartridge 13 in frictional engagement with each other to inhibit accidental rotation of cartridge 12 with respect to cartridge 13 .
- the purpose of limiting rotation between the two cartridges 12 and 13 to is use the static position of the base cartridge 13 with respect to the openings 33 in cartridge 12 as a means to select the number of openings 33 or the water flow through the openings located within a substantially hemi lune shaped gap 14 a, which is formed between a substantially radial face 16 and a substantially radial face 17 of cartridge 13 .
- By selecting the openings 33 or the flow area one can control the flow of water into and out of dispensing cartridge 12 and consequently the dispersant rate if the dispensing cartridge contains a water sensitive dispersant.
- Examples of water sensitive dispersants includes minerals for releasing metal ions and other materials that can be dispersed into the water to affect the water characteristics although no limitation to materials that can effect the water characteristics is intended since the dispensing cartridge may in some instances be used for holding other types of dispersant materials that do not impact the water characteristics.
- the openings 32 in dispensing cartridge may be fixed since the selection of openings in cartridge 12 allows one to coordinate the dispensing rates of the dispersants in cartridge 12 and cartridge 13 .
- ballast materials having a specific gravity greater than one such as sand or the like, may be placed in cartridge 13 if one wishes to convert the dual dispensing system to a single dispensing system without affecting the flotation characteristics of the system.
- a user may require minerals or the like that deliver metal ions, which are delivered from minerals contained in dispensing cartridge 13 and in another application the source of metal ions may not be required.
- the user can switch dispensing cartridge 13 , which contains minerals, for a dispensing cartridge that contains an inert material or ballast.
- one has the option of using the compartment that normally contains the minerals for holding other water dispersants or extra halogen, which can lengthen the operational life of the dispenser.
- the replacement of a batch of minerals with a ballast allows the spherical dispenser to functionally float in the same manner without delivering a second dispersant into the body of water.
- one may use inert ballast and in other cases one may use active ballast such as limestone, which has lesser effect on the water treatment than the combination of minerals such as limestone and silver chloride.
- FIG. 1C shows the second hemispherical cap or cartridge 12 revealing the circular top surface or base 15 with a set of openings 33 therein for ingress and egress of water to cartridge 12 .
- a reference to FIG. 1 reveals how only those openings 33 , which are located in the space provided by lune shaped gap 14 a, permit fluid communication to and from the materials in the dispensing cartridge 12 .
- FIG. 1C shows a cutaway view of hemispherical cap 12 revealing a chamber 30 b containing a plurality of halogen tablets or pucks 9 a. While halogen tablets are shown as the dispensable materials other dispensing materials may be used therein without departing from the spirit and scope of the invention.
- floating dispensers allows for insitu treatment of a body of water by placing the dispenser directly in the body of water, which allows the material to be delivered to the body of water through the contact of the water with the dispensers.
- two or more materials may be used in a chamber of the dispenser with one dispensable material having a long-term dissolution rate and the other dispensable material having a rapid dissolution rate.
- the invention includes the method of using a floating dispenser to deliver two or more water affecting materials, which change the water characteristics, from the same compartment, one a short term dispersant and the other a long term dispersant.
- a floating dispenser compartment to deliver two dispersants or water affecting materials is the placement of dichlor (Dichloroisocyanuric acid) and trichlor (Trichloroisocyanauric acid) in the same compartment to achieve both a rapid and an extended water treatment. That is, the dichlor dissipates quickly and provides a shock treatment to the body of water while the trichlor release of chlorine into the body of water occurs over an extended period of time.
- the invention allows the carrying and delivery of multiple dispersants in the dispensing compartment. For example, one may place a chelator such as copper sulfate, a clarifier and zinc in the dispenser.
- Base 15 of dispensing cartridge 12 includes a central located pocket 18 for receiving and axially restraining extension 19 a while permitting rotation of the extension 19 along a central axis extending through extension 19 and through dispensing cartridge 12 and 13 .
- a spherical floating dispenser 10 which is supported by an annular flotation collar 11 that is circumferentially external to the floating dispenser 10 .
- FIG. 1 shows the first hemispherical cap 13 includes a substantially hemi lune shaped gap 14 a formed between a set of substantially radial faces 16 and 17 in the first hemispherical cap 13 .
- the hemispherical cap 13 which is rotatable with respect to the second hemispherical cap 12 , enables an operator to control the open water flow area through the selection of the open fluid ports 33 to the chamber 30 a.
- FIG. 1D is a top view showing the annular flotation member 11 extending around the dispensing cartridge 13 to maintain both the cartridges in a condition where water can come into contact with the contents of the dispensing cartridges as they arc supported by flotation ring 11 .
- the flotation ring 11 may be an inflatable ring or a solid buoyant material that has sufficient buoyancy so as to support the dispensing cartridge 12 and the dispensing cartridge 13 when both cartridges contain a dispersant.
- the flotation ring should support cartridge 12 and cartridge 13 at a level where the openings 32 in dispensing cartridges 13 and the openings 33 in dispensing cartridges 12 are located below a water line to ensure that water comes into contact with the materials located in the chambers of the floating dispenser 10 .
- FIG. 1 shows a partial cutaway view of dispensing cartridges revealing the chamber 30 b therein with the dispersant 9 a comprising pucks or tablets 9 a of a halogen.
- the circular face or base 15 of dispensing cartridge 12 and the circular base or face 14 of dispensing cartridge 13 are located in a face-to-face condition with each other.
- FIG. 2 shows an example of a floating dispenser 20 where the floating dispenser includes dispensing cartridges of unequal size.
- the top hemispherical dispensing cap 21 includes a substantially hemi lune shaped gap 22 and a circular base 23 for forming face-to-face engagement with a top base 24 of the elongated cylindrical dispensing cartridge 25 in a manner identical to the dispensing cartridge 13 of FIG. 1 .
- the dispensing cartridge 25 typically may be used for holding a halogen such as chlorine or bromine.
- an extension 21 b on dispensing cap 21 fits within a pocket 27 in an identical manner to the extensions and pocket of the floating dispenser 10 , which allows the larger dispensing cartridge 25 to be interchanged with the dispensing cartridge 12 of dispenser 13 .
- Top base 24 of dispensing cartridge 25 includes openings 24 a which provide egress and ingress to a chamber therein.
- the larger dispensing cartridge permits more material to be held therein and thus can extend the operational life of the dispenser.
- the flotation collar 26 provided for dispensing cartridge may contain more flotation than the flotation collar 11 .
- FIG. 2 shows the annular floatation collar 26 that attaches to the exterior of dispensing cartridge 25 to hold at least a portion of the top dispensing cartridge 21 containing openings 21 a below a waterline. While floating dispenser 20 permits one to extended the dispensing life of the dispensers since the larger capacity of dispensing cartridge 25 allows one to hold a larger amount of halogen in the dispensing cartridge 25 , the rotational top hemispherical cap 21 also offers the user the flexibility to select the amount of dispersant from dispensing cartridge 21 since in some applications one may require more dispersant than in other applications.
- the annular flotation member 26 which can be attached to the upper part of cartridge 25 , provides flotation for both of the dispensers 21 and 25 .
- the flotation member may be adhesively secured to the cartridge 25 , however, other means may be used to secure the flotation member 26 to the dispensing cartridge 21 or 25 in a position where the openings 21 a and openings 24 a remain below the water line.
- FIG. 3 shows an example of another floating dispenser 30 with three identical but separate cylindrical members located in an end-to-end condition.
- a first cylindrical dispensing cartridge 31 which has water openings 31 a, may contain a dispersant such as minerals
- a second cylindrical member or floatation chamber 32 and a third cylindrical dispensing cartridge 36 , which has water openings 36 a may contain a halogen.
- the halogen such as bromine
- the center of gravity of the floating dispenser shifts. That is while the weight of the material in the first dispensing material i.e.
- dispensing cartridge 31 and 36 may be connected to floatation chamber 32 in the identical manner that dispensing cartridge 12 connects to dispensing cartridge 13 .
- FIG. 4 shows another example of a floating dispenser 40 with three members.
- the top member comprises a hemispherical cap 41 with a lune shaped gap 42 with the top member having an internal flotation chamber.
- a cylindrical member 45 for containing a dispersant such as halogen and having openings 45 a.
- a second hemispherical cap 43 having openings 43 a forming a mineral dispenser.
- each of the members are secured to an adjacent member to form a single dispenser with the top spherical cap 41 rotatable with respect to middle dispenser 45 to control the open area of ports therein (not shown) to thereby control the amount of water coming into contact with the halogen in the halogen dispenser 45 .
- Floating dispenser 40 is characterized as a non-inverting dispenser since the dispenser remains in the same vertical orientation during the consumption of the halogens since the both the dispensing chamber and the halogen chamber are located below the water line. If desired floating dispenser 40 may be converted to a dispenser that changes its orientation through consumption of a dispersant or through position of a flotation chamber within dispenser 45 .
- Floating dispenser 40 may then become an inverting dispenser similar to the floating dispenser 30 shown in FIG. 3 .
- FIG. 5 shows a floating dispenser 60 comprising an upper member 61 having a buoyant chamber 61 a for buoyantly supporting floating dispenser 60 in a body of water such as a pool or spa and a lower member 65 holding a dispersant 66 , such as a halogen therein.
- the lower portion of dispenser top 61 includes an annular lip 61 b with a set of openings 67 that can be aligned with a set of openings 68 that extend into a chamber 70 in the member 65 .
- Member 65 which is shown partially in section includes a cylindrical chamber 70 for holding a dispersant such as a halogen 66 .
- a ridge 69 on member 65 engages a groove 69 a in the annular lip 61 b to hold top member 61 in rotational engagement with member 65 .
- Rotation of member 61 with respect to member 65 aligns more or less of openings 68 with openings 67 to thereby control the amount of water that contact the dispersant in member 65 .
- the floating dispenser 60 can be converted to dispenser that delivers two dispersants rather than one dispersant or can also be converted into an inverting dispenser that inverts if only a single dispersant is present in dispenser 60 .
- a pouch 63 is inserted into dispenser top 61 .
- the pouch 63 has a set of openings 63 a and may contain a second dispersant such as minerals, which release metal ions, or the pouch 63 may contain an inert or ballast material 64 .
- the pouch 63 may be rigid or soft and may be held therein through frictional engagement. In either case the floating dispenser can be converted from a dispenser that flops when empty to a dispenser that inverts when the dispersants therein are spent. If the pouch contains a source of metal ions the conventional one dispersant dispenser becomes a two dispersant dispenser.
- FIG. 5A shows the dispensing cartridge 61 in a full condition with the dispenser 60 floating in an upright condition with dispensing cartridge 65 located below the water line 8 , which is the interface between the water and the atmosphere.
- the floating dispenser reaches a point where the dispensing cartridge 60 floats on its side as shown in FIG. 5B . This would be the normal flop condition for dispenser 60 if the pouch or container was not present in dispenser 60 .
- the pouch containing a ballast or dispersant that delivers a water treatment material without decreasing the mass of the dispersant, i.e. minerals or other materials that deliver metal ions.
- the dispersant 66 continues to dissipate the dispenser 60 reaches a condition where the dispersant in the dispenser cartridge has been consumed.
- the ballast 64 which was above the center of gravity of the dispenser 60 when the dispenser contained a dispensable material would now be below the center of gravity of dispenser 60 causing dispenser 60 to invert to the condition shown in FIG. 5C .
- the dispenser 60 can be converted from a flopping dispenser to an inverting dispenser that alerts a person that the dispenser needs a refill through the end for end inversion of the dispenser.
- FIG. 5D shows an isolated view of the container or pouch 63 that is inserted into floating dispenser 60 to convert the floating dispenser to either a floating dispenser that simultaneously delivers two dispersants or by selecting the proper weight of material a floating dispenser that will invert 180 degrees.
- Pouch 63 includes a cylindrical side-wall 71 , a material 64 and a set of openings 63 a for ingress and egress of water.
- the container or pouch 63 may contain an inert material or a material that has an effect on the water characteristics although the mass of the material remains stable. Examples of such materials include materials that deliver metal ions, such as minerals, which are commonly used in water treatment. Placement of weighted material in an upper chamber of dispenser 60 as illustrated in FIG.
- the dispenser 60 may also be used to affect the flotation characteristics of the floating dispenser 60 . That is, if the buoyancy of the bottom member without the dispersant therein is greater than the buoyancy of the top member 61 the placement of a consumable dispersant 66 in a lower compartment chamber 70 with the weight of the consumable dispersant greater than the weight of the material in the upper compartment 61 of the dispenser 60 can cause the dispenser 60 to float in the condition shown in FIG. 5A and when the dispersant 66 is consumed the dispenser 60 inverts to the condition shown in FIG. 5C .
- the invention includes a method of water treatment of a pool or spa with a flotation dispenser 60 comprises the steps of placing a container 63 of material 64 in a water accessible compartment of a first member 61 of the floatation dispenser 60 wherein the material 64 maintains its mass during a dispensing cycle. Placing a water treatment material 66 such as a halogen in a water accessible compartment 70 of a second member 65 which is securable to the first member 61 with second water treatment material 66 having the characteristic of losing its mass during a dispensing cycle whereby the floating dispenser has a flotation axis in a first orientation when in a full condition as shown in FIG. 5A and a second flotation axis in a visible different orientation ( FIG. 5B , FIG. 5C ) when the dispersant 66 in the second member loses its mass to the body of water.
- a water treatment material 66 such as a halogen in a water accessible compartment 70 of a second member 65 which is securable to the first member 61
- FIG. 6 shows an example of another type of floating dispenser i. e. a floating spoke dispenser 50 where the presence of one or more of the spoke cartridges proximate the water line indicates that a spoke cartridge dispenser should be replenished.
- the floating spoke dispenser 50 comprises a cylindrical or spherical hub 51 forming a central cylindrical float with the hub 51 having a first dispenser cartridge 54 , which has openings 54 a, in the shape of a cylindrical spoke extending radially outward from one side of hub 51 .
- a second dispenser cartridge 52 which has openings 52 a
- a third dispensing cartridge 53 which has openings 53 a with each in the shape of a cylindrical spoke extend radially outward from hub 51 with each of the cylindrical dispensing cartridges preferably located at equal horizontal angles of approximately 120 degrees with respect to an adjacent spoke cartridge.
- each of the spoke cartridges are of equal size, however, the spoke cartridges may be of different size or located at different angles with respect to each other without departing from the spirit and scope of the invention, however to obtain the benefit of visual observation that a spoke cartridge is empty the spoke cartridge should be positioned so that the vertical angle of the spokes with respect to the horizon becomes visible to an observer when the dispersant therein is consumed.
- the floating dispenser 50 includes a cylindrical shaped flotation member 51 ; a first dispensing cartridge 54 extending radially from the flotation member 51 ; a second dispensing cartridge 52 extending radially from the flotation member 51 ; and a third dispensing cartridge 53 extending radially from the flotation member 51 with each of the dispensing cartridges having a central axis forming an acute angle with respect to a horizon to enable each of a set of ports 54 a, 52 a and 53 a on each of the dispensing cartridges to be located below a water line 8 when a dispersant is present therein.
- the spoke cartridges may be rotateably mounted to the hub for removal and insertion of a fresh cartridge.
- FIG. 7 shows that the three spoke cartridges 52 , 53 and 54 each extend radially outward from hub 51 at an acute angle of about 30 degrees with respect to the water line 8 .
- one of the spoke cartridge 54 may contain minerals, which releases metal ions into the body of water. The release of metal ions has little or no effect on the weight of the minerals in the spoke cartridge 54 .
- the other spoke cartridge 52 may contain a halogen such as bromine, which is dissolvable and dispersible into the body of water and which does have an effect on the weight of the dispensing cartridges 52 and spoke cartridge 53 may contain a third dispersant that is different from the other dispersants 53 or that may be same as another cartridge.

- The concept of floating dispensers for delivering a dispersant or dispersants to a body of water is known in the art. In one type of floating dispensers the dispensers contain a halogen and float upright in a body of water until the halogen is consumed whereupon the dispenser flops on its side. In another type of dispenser the dispenser sinks to the bottom of the pool and remains there until the dispersant has been consumed at which time the dispenser floats to the top of the pool to alert the operator to replace the dispenser. In another type of a floating dispenser a nondissolvable weight, such as a marble, is included in the dispenser with the dispenser floating on its side when the dispersant is consumed. As the dispenser floats on its side the marble rolls along the interior of the dispenser and transfers the weigh to the end of the dispenser causing to dispenser to invert after the dispersant is consumed.
- A floating dispenser having an external float or an internal float for supporting a cartridge or cartridges for floatingly delivering a dispersant or dispersants to a body of water with the floating dispenser having cartridges rotationally positionable with respect to one another to control the rate of dispensing while the dispenser floats in an upright condition. In some cases the floating dispenser changes its flotation orientation in response to consumption of the dispersant or dispersants in the a cartridge to thereby provide a visual alert to replace a spent cartridge with a fresh cartridge which can be done by removing the spent cartridge from the dispenser and attaching the fresh cartridge to the floating dispenser. While the dispensers shown herein are suitable for use in pools spas and the like other uses may be found by those in the water treatment field. In addition the inventions described herein permit changing the dispensing nature of the system from a multiple dispensing system to a single dispensing system without changing the floating characteristics of the floating dispensers through replacement of a dispersant in one of the cartridges with an inert or ballast material that has no effect on the water characteristics.

FIG. 1 shows a perspective view of a spherical floating status-indicatingdispenser 10 for use in pools, spas or other bodies of water that require water treatment such as killing harmful organisms in the water or affecting other characteristics of the water by releasing a dispersant therein.Dispenser 10 comprises twohemispherical cartridges cartridges cap 13 having a circular base and apole region 13 a and the second hemispherical dispenser similarly, having a hemispherical cartridge orcap 12 having apole region 12 a.FIG. 1A shows a perspective view of thehemispherical cartridge 13 revealing acircular base 14 having a pie shaped section removed therefrom and acentral extension 19 extending from a central axis of the dispensingcartridge 12 whileFIG. 1B shows a side view of thehemispherical cartridge 13. -
FIG. 1 ,FIG. 1A andFIG. 1B show that the first hemispherical cap orcartridge 13 contains achamber 30 a and a set offluid openings 32 for ingress and egress of water to chamber, 30 a, which for example, may contain a batch of minerals 9 for delivering metal ions into a body of water. Examples of minerals usable in dispensers may be found in U.S. Pat. No. 6,500,334, which is hereby incorporated by reference.Chamber 30 a may be used to hold other materials including inert items, which are used for ballast in thedispenser 10 when the dispenser is changed from a dual dispensing mode to a single dispensing mode. Located on the underside ofcap 13 is theelongated extension 19 and a taperedhead 19 a that can be used to engage and rotationally securehemispherical cartridge 13 tohemispherical cartridge 12 through a base-to-base relationship that permits one to rotatecartridge 12 with respect tocartridge 13 to select an appropriate dispensing rate. Typically,extension 19 holds thebase 15 ofcartridge 12 andbase 14 ofcartridge 13 in frictional engagement with each other to inhibit accidental rotation ofcartridge 12 with respect tocartridge 13. The purpose of limiting rotation between the twocartridges base cartridge 13 with respect to theopenings 33 incartridge 12 as a means to select the number ofopenings 33 or the water flow through the openings located within a substantially hemi lune shapedgap 14 a, which is formed between a substantiallyradial face 16 and a substantiallyradial face 17 ofcartridge 13. By selecting theopenings 33 or the flow area one can control the flow of water into and out of dispensingcartridge 12 and consequently the dispersant rate if the dispensing cartridge contains a water sensitive dispersant. Examples of water sensitive dispersants includes minerals for releasing metal ions and other materials that can be dispersed into the water to affect the water characteristics although no limitation to materials that can effect the water characteristics is intended since the dispensing cartridge may in some instances be used for holding other types of dispersant materials that do not impact the water characteristics. On the other hand theopenings 32 in dispensing cartridge may be fixed since the selection of openings incartridge 12 allows one to coordinate the dispensing rates of the dispersants incartridge 12 andcartridge 13. - An example of use of a different type of material which can affect the delivery of dispersants from the floating dispenser but not the operation of the floating dispenser is the placement of inert materials or ballast in
dispenser 12 which may be done without departing from the spirit and scope of the invention. That is ballast materials having a specific gravity greater than one, such as sand or the like, may be placed incartridge 13 if one wishes to convert the dual dispensing system to a single dispensing system without affecting the flotation characteristics of the system. By employing a set of dispensingcartridges cartridge 13 and in another application the source of metal ions may not be required. The user can switch dispensingcartridge 13, which contains minerals, for a dispensing cartridge that contains an inert material or ballast. Alternately, one has the option of using the compartment that normally contains the minerals for holding other water dispersants or extra halogen, which can lengthen the operational life of the dispenser. The replacement of a batch of minerals with a ballast allows the spherical dispenser to functionally float in the same manner without delivering a second dispersant into the body of water. In some cases one may use inert ballast and in other cases one may use active ballast such as limestone, which has lesser effect on the water treatment than the combination of minerals such as limestone and silver chloride. -
FIG. 1C shows the second hemispherical cap orcartridge 12 revealing the circular top surface orbase 15 with a set ofopenings 33 therein for ingress and egress of water tocartridge 12. A reference toFIG. 1 reveals how only thoseopenings 33, which are located in the space provided by lune shapedgap 14 a, permit fluid communication to and from the materials in the dispensingcartridge 12.FIG. 1C shows a cutaway view ofhemispherical cap 12 revealing achamber 30 b containing a plurality of halogen tablets orpucks 9 a. While halogen tablets are shown as the dispensable materials other dispensing materials may be used therein without departing from the spirit and scope of the invention. - The use of floating dispensers allows for insitu treatment of a body of water by placing the dispenser directly in the body of water, which allows the material to be delivered to the body of water through the contact of the water with the dispensers. In some cases two or more materials may be used in a chamber of the dispenser with one dispensable material having a long-term dissolution rate and the other dispensable material having a rapid dissolution rate. For example, one can place alum together with a batch of minerals in one compartment. The alum, which dissipates quickly acts as a clarifier, while the minerals continue to deliver silver ions to the body of water over an extended period of time which can be weeks or months. Thus, the invention includes the method of using a floating dispenser to deliver two or more water affecting materials, which change the water characteristics, from the same compartment, one a short term dispersant and the other a long term dispersant. Another example, of using the floating dispenser compartment to deliver two dispersants or water affecting materials is the placement of dichlor (Dichloroisocyanuric acid) and trichlor (Trichloroisocyanauric acid) in the same compartment to achieve both a rapid and an extended water treatment. That is, the dichlor dissipates quickly and provides a shock treatment to the body of water while the trichlor release of chlorine into the body of water occurs over an extended period of time. In addition to the use of two dispersants the invention allows the carrying and delivery of multiple dispersants in the dispensing compartment. For example, one may place a chelator such as copper sulfate, a clarifier and zinc in the dispenser.

Base 15 of dispensingcartridge 12 includes a central locatedpocket 18 for receiving and axially restrainingextension 19 a while permitting rotation of theextension 19 along a central axis extending throughextension 19 and through dispensingcartridge hemispherical cap 13 and thehemispherical cap 12 are in axial alignment and engaged with each other as shown inFIG. 1 they form a spherical floatingdispenser 10 which is supported by an annular flotation collar 11 that is circumferentially external to the floatingdispenser 10. -
FIG. 1 shows the firsthemispherical cap 13 includes a substantially hemi lune shapedgap 14 a formed between a set of substantially radial faces 16 and 17 in the firsthemispherical cap 13. Thehemispherical cap 13, which is rotatable with respect to the secondhemispherical cap 12, enables an operator to control the open water flow area through the selection of theopen fluid ports 33 to thechamber 30 a. - Extending circumferentially in an equatorial position around the
hemispherical dispensing cartridge 12 andhemispherical dispensing cartridge 13 is the annular flotation collar 11, which is secured to one or the other of the cartridges, preferably at the base of the cartridges to provide flotation to thecartridges FIG. 1 .FIG. 1D is a top view showing the annular flotation member 11 extending around the dispensingcartridge 13 to maintain both the cartridges in a condition where water can come into contact with the contents of the dispensing cartridges as they arc supported by flotation ring 11. The flotation ring 11 may be an inflatable ring or a solid buoyant material that has sufficient buoyancy so as to support the dispensingcartridge 12 and the dispensingcartridge 13 when both cartridges contain a dispersant. The flotation ring should supportcartridge 12 andcartridge 13 at a level where theopenings 32 in dispensingcartridges 13 and theopenings 33 in dispensingcartridges 12 are located below a water line to ensure that water comes into contact with the materials located in the chambers of the floatingdispenser 10. - In the example shown in
FIG. 1 thehemispherical dispensing cartridges extension 19 holding the dispensing cartridges in a rotatable condition with respect to each other. The substantially hemi lune shaped opening 14 a providing means for selecting the size of an open region inspherical cap 13 and for uncovering more orless ports 33 in thebase 15 ofspherical cap 12.FIG. 1C shows a partial cutaway view of dispensing cartridges revealing thechamber 30 b therein with thedispersant 9 a comprising pucks ortablets 9 a of a halogen. In the assembled condition the circular face orbase 15 of dispensingcartridge 12 and the circular base or face 14 of dispensingcartridge 13 are located in a face-to-face condition with each other. - While
FIG. 1 shows dispensing cartridges of the same sizeFIG. 2 shows an example of a floatingdispenser 20 where the floating dispenser includes dispensing cartridges of unequal size. In this example, the tophemispherical dispensing cap 21 includes a substantially hemi lune shapedgap 22 and acircular base 23 for forming face-to-face engagement with atop base 24 of the elongatedcylindrical dispensing cartridge 25 in a manner identical to the dispensingcartridge 13 ofFIG. 1 . The dispensingcartridge 25 typically may be used for holding a halogen such as chlorine or bromine. In this example an extension 21 b on dispensingcap 21 fits within apocket 27 in an identical manner to the extensions and pocket of the floatingdispenser 10, which allows thelarger dispensing cartridge 25 to be interchanged with the dispensingcartridge 12 ofdispenser 13.Top base 24 of dispensingcartridge 25 includesopenings 24 a which provide egress and ingress to a chamber therein. The larger dispensing cartridge permits more material to be held therein and thus can extend the operational life of the dispenser. To compensate for the additional material theflotation collar 26 provided for dispensing cartridge may contain more flotation than the flotation collar 11. -
FIG. 2 shows theannular floatation collar 26 that attaches to the exterior of dispensingcartridge 25 to hold at least a portion of thetop dispensing cartridge 21 containing openings 21 a below a waterline. While floatingdispenser 20 permits one to extended the dispensing life of the dispensers since the larger capacity of dispensingcartridge 25 allows one to hold a larger amount of halogen in the dispensingcartridge 25, the rotational tophemispherical cap 21 also offers the user the flexibility to select the amount of dispersant from dispensingcartridge 21 since in some applications one may require more dispersant than in other applications. - As shown the
annular flotation member 26, which can be attached to the upper part ofcartridge 25, provides flotation for both of thedispensers cartridge 25, however, other means may be used to secure theflotation member 26 to the dispensingcartridge openings 24 a remain below the water line. -
FIG. 3 shows an example of another floatingdispenser 30 with three identical but separate cylindrical members located in an end-to-end condition. In this example, a firstcylindrical dispensing cartridge 31, which has water openings 31 a, may contain a dispersant such as minerals, a second cylindrical member orfloatation chamber 32, and a thirdcylindrical dispensing cartridge 36, which haswater openings 36 a may contain a halogen. In this example when the halogen such as bromine is consumed the center of gravity of the floating dispenser shifts. That is while the weight of the material in the first dispensing material i.e. such as minerals or ballast, does not dissolve, the consummation of the halogen causing the center of gravity of thedispenser 30 to shift from the bottom cartridge to the top cartridge which causes thedispenser 30 to invert with thecylindrical dispenser 36 containing the empty halogen chamber appearing above the water line rather than the cylindrical chamber containing the minerals or ballast. By selecting different colors for thecylindrical dispenser cartridge cartridge 31 with the nondissolvable materials, i.e. minerals or ballast, may be blue and thedispenser cartridge 36 may be red so that when the floatingdispenser 30 inverts the appearance of thered cartridge 36 above the water line alerts an operator to replace the spentdispenser cartridge 36 in the floatingdispenser 30. While not shown dispensingcartridges floatation chamber 32 in the identical manner that dispensingcartridge 12 connects to dispensingcartridge 13. -
FIG. 4 shows another example of a floatingdispenser 40 with three members. In this example the top member comprises a hemispherical cap 41 with a lune shapedgap 42 with the top member having an internal flotation chamber. Located below the hemispherical cap 41 is acylindrical member 45 for containing a dispersant such as halogen and havingopenings 45 a. Located belowdispenser 45 is a secondhemispherical cap 43 havingopenings 43 a forming a mineral dispenser. In this example each of the members are secured to an adjacent member to form a single dispenser with the top spherical cap 41 rotatable with respect tomiddle dispenser 45 to control the open area of ports therein (not shown) to thereby control the amount of water coming into contact with the halogen in thehalogen dispenser 45. Floatingdispenser 40 is characterized as a non-inverting dispenser since the dispenser remains in the same vertical orientation during the consumption of the halogens since the both the dispensing chamber and the halogen chamber are located below the water line. If desired floatingdispenser 40 may be converted to a dispenser that changes its orientation through consumption of a dispersant or through position of a flotation chamber withindispenser 45. With the floatingdispenser 40 an operator has the option of changing the dispensingcartridge 45 to a flotation cartridge whilehemispherical cap 41 and 43 become dispenser cartridges for water treatment materials. Floatingdispenser 40 may then become an inverting dispenser similar to the floatingdispenser 30 shown inFIG. 3 . -
FIG. 5 shows a floatingdispenser 60 comprising anupper member 61 having a buoyant chamber 61 a for buoyantly supporting floatingdispenser 60 in a body of water such as a pool or spa and alower member 65 holding adispersant 66, such as a halogen therein. The lower portion ofdispenser top 61 includes anannular lip 61 b with a set ofopenings 67 that can be aligned with a set ofopenings 68 that extend into achamber 70 in themember 65.Member 65, which is shown partially in section includes acylindrical chamber 70 for holding a dispersant such as ahalogen 66. Aridge 69 onmember 65 engages agroove 69 a in theannular lip 61 b to holdtop member 61 in rotational engagement withmember 65. Rotation ofmember 61 with respect tomember 65 aligns more or less ofopenings 68 withopenings 67 to thereby control the amount of water that contact the dispersant inmember 65. Through the use of an container orpouch 63 the floatingdispenser 60 can be converted to dispenser that delivers two dispersants rather than one dispersant or can also be converted into an inverting dispenser that inverts if only a single dispersant is present indispenser 60. In this example, apouch 63 is inserted intodispenser top 61. Thepouch 63 has a set ofopenings 63 a and may contain a second dispersant such as minerals, which release metal ions, or thepouch 63 may contain an inert orballast material 64. Thepouch 63 may be rigid or soft and may be held therein through frictional engagement. In either case the floating dispenser can be converted from a dispenser that flops when empty to a dispenser that inverts when the dispersants therein are spent. If the pouch contains a source of metal ions the conventional one dispersant dispenser becomes a two dispersant dispenser. - A reference to
FIG. 5A ,FIG. 5B andFIG. 5C reveals the operation ofdispenser 60 after a pouch or container has been inserted intodispenser 60.FIG. 5A shows the dispensingcartridge 61 in a full condition with thedispenser 60 floating in an upright condition with dispensingcartridge 65 located below thewater line 8, which is the interface between the water and the atmosphere. As the dispersant indispenser 60 dissipates, the floating dispenser reaches a point where the dispensingcartridge 60 floats on its side as shown inFIG. 5B . This would be the normal flop condition fordispenser 60 if the pouch or container was not present indispenser 60. However, with the pouch containing a ballast or dispersant that delivers a water treatment material without decreasing the mass of the dispersant, i.e. minerals or other materials that deliver metal ions. As thedispersant 66 continues to dissipate thedispenser 60 reaches a condition where the dispersant in the dispenser cartridge has been consumed. In this condition theballast 64 which was above the center of gravity of thedispenser 60 when the dispenser contained a dispensable material would now be below the center of gravity ofdispenser 60 causingdispenser 60 to invert to the condition shown inFIG. 5C . Thus, through the addition to a pouch or container containing a second material thedispenser 60 can be converted from a flopping dispenser to an inverting dispenser that alerts a person that the dispenser needs a refill through the end for end inversion of the dispenser. -
FIG. 5D shows an isolated view of the container orpouch 63 that is inserted into floatingdispenser 60 to convert the floating dispenser to either a floating dispenser that simultaneously delivers two dispersants or by selecting the proper weight of material a floating dispenser that will invert 180 degrees.Pouch 63 includes a cylindrical side-wall 71, amaterial 64 and a set ofopenings 63 a for ingress and egress of water. Alternately, the container orpouch 63 may contain an inert material or a material that has an effect on the water characteristics although the mass of the material remains stable. Examples of such materials include materials that deliver metal ions, such as minerals, which are commonly used in water treatment. Placement of weighted material in an upper chamber ofdispenser 60 as illustrated inFIG. 5 may also be used to affect the flotation characteristics of the floatingdispenser 60. That is, if the buoyancy of the bottom member without the dispersant therein is greater than the buoyancy of thetop member 61 the placement of aconsumable dispersant 66 in alower compartment chamber 70 with the weight of the consumable dispersant greater than the weight of the material in theupper compartment 61 of thedispenser 60 can cause thedispenser 60 to float in the condition shown inFIG. 5A and when thedispersant 66 is consumed thedispenser 60 inverts to the condition shown inFIG. 5C . - Thus the invention includes a method of water treatment of a pool or spa with a
flotation dispenser 60 comprises the steps of placing acontainer 63 ofmaterial 64 in a water accessible compartment of afirst member 61 of thefloatation dispenser 60 wherein thematerial 64 maintains its mass during a dispensing cycle. Placing awater treatment material 66 such as a halogen in a wateraccessible compartment 70 of asecond member 65 which is securable to thefirst member 61 with secondwater treatment material 66 having the characteristic of losing its mass during a dispensing cycle whereby the floating dispenser has a flotation axis in a first orientation when in a full condition as shown inFIG. 5A and a second flotation axis in a visible different orientation (FIG. 5B ,FIG. 5C ) when thedispersant 66 in the second member loses its mass to the body of water. -
FIG. 6 shows an example of another type of floating dispenser i. e. a floating spoke dispenser 50 where the presence of one or more of the spoke cartridges proximate the water line indicates that a spoke cartridge dispenser should be replenished. The floating spoke dispenser 50 comprises a cylindrical orspherical hub 51 forming a central cylindrical float with thehub 51 having afirst dispenser cartridge 54, which hasopenings 54 a, in the shape of a cylindrical spoke extending radially outward from one side ofhub 51. Similarly asecond dispenser cartridge 52, which hasopenings 52 a, and athird dispensing cartridge 53, which hasopenings 53 a with each in the shape of a cylindrical spoke extend radially outward fromhub 51 with each of the cylindrical dispensing cartridges preferably located at equal horizontal angles of approximately 120 degrees with respect to an adjacent spoke cartridge. In the example shown, each of the spoke cartridges are of equal size, however, the spoke cartridges may be of different size or located at different angles with respect to each other without departing from the spirit and scope of the invention, however to obtain the benefit of visual observation that a spoke cartridge is empty the spoke cartridge should be positioned so that the vertical angle of the spokes with respect to the horizon becomes visible to an observer when the dispersant therein is consumed. Typically, an angle of 30 degrees allows one to visually determine when a cartridge has been spent. In this example the floating dispenser 50 includes a cylindrical shapedflotation member 51; afirst dispensing cartridge 54 extending radially from theflotation member 51; asecond dispensing cartridge 52 extending radially from theflotation member 51; and athird dispensing cartridge 53 extending radially from theflotation member 51 with each of the dispensing cartridges having a central axis forming an acute angle with respect to a horizon to enable each of a set ofports water line 8 when a dispersant is present therein. In this example the spoke cartridges may be rotateably mounted to the hub for removal and insertion of a fresh cartridge. -
FIG. 7 shows that the three spokecartridges hub 51 at an acute angle of about 30 degrees with respect to thewater line 8. In operation as a typical floating dispenser one of thespoke cartridge 54 may contain minerals, which releases metal ions into the body of water. The release of metal ions has little or no effect on the weight of the minerals in thespoke cartridge 54. Theother spoke cartridge 52 may contain a halogen such as bromine, which is dissolvable and dispersible into the body of water and which does have an effect on the weight of the dispensingcartridges 52 and spokecartridge 53 may contain a third dispersant that is different from theother dispersants 53 or that may be same as another cartridge. Various types of materials may be used in each of the dispensing cartridges depending on the materials needed to affect the characteristics of the water. As the halogen in thespoke dispensing cartridges heavier dispensing cartridge 54 with no consumables to rotate downward toward an under water vertical axis while each of the halogen spoke dispensingcartridges water line 8 as indicated by the arrows. Consequently the position of the spoke cartridges with respect to thewater line 8 becomes an indicator of the need to replenish the halogen since the empty spoke cartridges will be visible on or at thewater line 8. -
FIG. 8 shows an exploded view of further embodiment of a floatingcylindrical dispenser 90 having a removable cylindrical top-dispensingmember 91 having ahandle 95 for rotating dispensingmember 91 with respect tolower dispenser member 92. Located within dispensingmember 91 is a chamber therein for holding a water affecting dispersant such as a halogen with the dispensingmember 91 having a set offluid ports 94 to permit ingress and egress of water. The topcylindrical member 91 is rotateably mounted in a cylindrical opening in thelower dispenser member 92 while theexternal floatation collar 93, which is located radially outward from thelower dispenser member 92, provides buoyancy to thedispenser 90. In this example theminerals 98 are located in the bottom oflower dispenser member 92 and the center of gravity of the unit remains below the water line whether the halogen chamber is empty or contains a halogen. Means such as shown inFIG. 1B may be used to hold topcylindrical member 91 in a rotatable condition proximatelower dispenser member 92. - To control the flow of water into the chamber in
top member 91 one can rotatecylindrical member 91 with respect to lowercylindrical member 92 thereby bringing more or less of openings into an exposed condition inwindow 97 thus allowing one to control the rate of dispersion of a dispersant such as a halogen through a change in the flow area. The lowercylindrical member 92 includesopenings 92 a to permit the ingress and egress of water therethrough to enable the dissipation of the metal ions into the water. -
FIG. 9 shows a further example of a floatingcylindrical dispenser 73 having a top cylindricaltop member 74 having a replaceable halogen cartridge therein with a set offluid ports 76 located in window 78 of thelower member 75. The topcylindrical member 74 is rotationally mounted in an opening in thelower member 75. In this example a flotation chamber is located internally in topcylindrical member 74. In this example, the minerals are also located in the bottom oflower dispenser member 75 and the center of gravity of the unit remains below the geometric center whether the halogen chamber is empty or full.Fluid ports 75 a permit water to flow into or out of thelower dispenser member 75. -
FIG. 10 shows a further example of a floatingcylindrical dispenser 80 having a topcylindrical member 81 having a replaceable halogen cartridge (not shown) therein with a set of fluid ports 83 located inwindow 85 of the bottom cylindrical member 82 to permit water to come into contact with the halogen intop member 81. The topcylindrical member 81 is rotateably mounted in an opening in the lower member 82. In this example a flotation chamber may be located in topcylindrical member 81. The minerals, which release metal ions, are also located in the bottom dispenser 82 ofdispenser 80 and the center of gravity of the unit remains below the geometric center whether the halogen chamber is empty or full. To provide an indicating of the status of the halogen in the dispenser the cylindrical face ofmember 81 includes a set offloat lines 86 that can be compared to the water line as the dispenser floats in a body of water. When the halogen is in an undissolved state the float line labeled by “full” will correspond with the water line. As the halogen reaches a dispensed state the float line labeled “empty” corresponds with the water line thus alerting an operator that the halogen chamber should be refilled. - In the embodiments shown two dispensing cartridges are secured to each other to provide a floating dispenser, however, additional dispensing cartridges for other water treatment materials may be incorporated into the floating dispenser without departing from the spirit and scope of the invention.
- While the invention has been described in regard to placement of a dispenser containing water affecting materials such as a halogen and minerals other dispersant may be used. If at least one of the water affecting materials is a water dispersible material that dissipates into the water form a container that floats in the body of water the floating condition of the
dispenser 80 provides an indication when the dispersible material is spent. While each of the embodiments ofFIGS. 8, 9 and 10 contain means for adjusting the delivery of the water affecting characteristics in a body of water such as a pool or spa it should be understood that the floating dispensers described herein may be used in other non-pool or non spa applications where water conditions need correcting.
