Multi-Nozzle Multi-Container Fluid Spray Device

BACKGROUND
Field of the Invention

This disclosure relates to fluid delivery devices and containers including fluid spray bottles.

BACKGROUND OF THE INVENTION

A variety of industries use bottles and other containers to store fluids and deliver them in the form of a spray nozzle or nebulizer. These industries include, but are not limited to, household cleaning, automotive, lawn and garden, medical, beauty and cosmetics, dental, and any market which utilizes trigger spray bottles.

Often tasks require multiple solutions requiring the user to manage multiple containers which may be inconvenient for the user. For example, a task may require the use of three different solutions which must be applied sequentially and possibly within a short time period of each other. In this scenario, the user must carry three separate bottles to the location where the task will be performed and move between the use of each bottle. A single container which could store, yet keep separate, the multiple solutions and deliver each separately or in a defined combination would be more convenient for the user.

In addition, the user must store three separate containers between uses. A single container which stores multiple fluids in separate compartments would require less storage space.

Furthermore, when multiple fluids are supplied in separate containers, each container results in a separate piece of waste in a landfill. A container which stores separate fluids in refillable compartments may reduce the amount of waste and negative impact on the environment.

BRIEF SUMMARY OF THE INVENTION

We disclose a multi-nozzle multi-container fluid spray device which includes a plurality of containers, each of which may each hold a different fluid. The multi-nozzle multi-container fluid spray device may include a single spray head with a single trigger in connection with a plurality of pumps. A hose may extend from each pump into one of a plurality of containers. The spray head may also include a plurality of nozzle ends. A tube may extend from each pump to one of a plurality of nozzle ends which may dispense fluid through one of a plurality of orifices in a fluid dispenser. In some embodiments, the plurality of each of these parts may be three of each part.

The plurality of pumps may be enclosed within a rotatable pump carriage which is in mechanical connection with a selector switch indicator. A user may move the selector switch indicator to one of a plurality of selector switch positions to select which container to access and, accordingly, which fluid to dispense. When the rotatable pump carriage moves the plurality of pumps, a single pump will be disposed in a position in which it is in mechanical connection with the single trigger. In some embodiments, this may be a center position in alignment with a fluid dispenser on the front of the spray head. A user may dispense the desired fluid from the desired container upon squeezing the trigger.

The multi-nozzle multi-container fluid spray device may include a container release device which may be reversibly connected to the top of each of the plurality of containers. The container release device may include a container release housing. The container release housing may include a plurality of walls which may partially define a plurality of orifices. A container may be inserted into each orifice. A lip may be disposed at the lower edge of each of the plurality of walls. A container may be inserted into each orifice and the lip may snap over the top of the container thereby holding the container in place. A release clip may also partially define each of the orifices. Each release clip may also snap over the top of one of the containers.

The container release device may also include a plurality of push buttons which may, in turn, be in mechanical connection with a plurality of release bars. Each of the plurality of release bars may be in mechanical connection with one of the plurality of release clips. In some embodiments, the container release device includes a spring-loaded mechanism. By pushing one of the push buttons, the release bar connected to it may, in turn, apply pressure to the adjacent release clip. The release bar may push the release clip outward, reversibly expanding the orifice. The container may slip out of the orifice and the release clip may return to its original position.

In some embodiments, the multi-nozzle multi-container fluid spray device is a triple-nozzle spray container. In an example, some embodiments include three containers. In an example, some embodiments include, three pumps, three hoses, and three nozzles. In an example, the container release mechanism includes three push buttons.

The plurality of containers may be reversibly connected to each other. For example, they may be interlocking through a mechanism which may include interlocking male and female notches. The opening of each of the containers may be covered by a seal. Each seal may comprise a hose receptacle through which one of the plurality of hoses may be reversibly inserted.

As used herein, “for example,” “for instance,” “such as,” or “including” are meant to introduce examples that further clarify more general subject matter. Unless otherwise expressly indicated, such examples are provided only as an aid for understanding embodiments illustrated in the present disclosure and are not meant to be limiting in any fashion. Nor do these phrases indicate any kind of preference for the disclosed embodiment.

While this invention is susceptible of embodiment in many different forms, there are shown in the drawings, which will herein be described in detail, several specific embodiments with the understanding that the present disclosure is to be considered as an exemplification of the principals of the invention and is not intended to limit the invention to the illustrated embodiments.

The disclosed multi-nozzle multi-container fluid spray device solves the problem of needing multiple containers of different liquid spray solutions by combining multiple containers into one device thus providing a flexible tool for the user. It also reduces waste which may fill landfills by providing a mechanism to refill each container. The disclosed multi-nozzle multi-container fluid spray device is also more convenient for the user and saves time, money, and resources.

The disclosed multi-nozzle multi-container fluid spray device includes multiple containers which may each hold a different liquid. The containers may be bottles, tubes, sleeves, flasks, jars, packets, cans, drums, or any container known in the art which may hold a liquid. In an example, the multi-nozzle multi-container fluid spray device includes two, three, four, five, or six containers.

Each of the multiple containers may be reversibly connected to another container. In the example in which the plurality of containers includes three containers, each container is reversibly connected to two other containers.

The multiple containers may be reversibly connected by being interlocking with each other. In an example, the containers may each include one or more male notches and one or more female notches. A male notch of one container may insert into the female notch of one or more adjacent containers.

Each of the containers may include a top rim which defines an opening. In some embodiments, the top rim of one or more of the containers is covered by a seal. Each seal may include a hose receptacle. The hose receptacles may be constructed of an easily perforated material through which the end of a hose extending from the spray head may extend. In an example, the hose receptacles may be constructed of foil, wax paper, or plastic.

The containers may be disposable, replaceable, or refillable. They may be constructed of a recyclable material. In some embodiments, the containers are constructed of glass, one or more plastic polymers, foil, recyclable material, biodegradable material, paper, wax paper, or hemp plastic.

In some embodiments, the containers include finger indentations onto which a user may place his or her finger to aid in gripping the multi-nozzle multi-container fluid spray device during use. Similarly, thumb indentations may be included on the containers. In some embodiments, the finger and thumb indentations include ridges to further improve gripping. The containers may have curved or custom-molded lines to fit into the user's hand comfortably during use.

The multi-nozzle multi-container fluid spray device may include a spray head which is in mechanical connection with each of the plurality of containers. In some embodiments, the spray head may include a plurality of nozzles. Some embodiments may include the same number of nozzles as containers. Other embodiments may include a single nozzle in fluid communication with a plurality of pumps. Each nozzle may be independently turned to an “off” position while the other nozzles may be open and available to dispense fluid. In some embodiments, each nozzle may be selected from the following list: a plain-orifice nozzle, a shaped-orifice nozzle, a surface-impingement single-fluid nozzle, a spiral spray nozzle, a pressure-swirl single-fluid spray nozzle, a spillback nozzle, and a solid-cone single-fluid nozzle. In some embodiments, one or more of the nozzles may be adjustable and able to deliver a range of densities of fluid particles by passing the fluid through a region of a mesh which includes different regions with different size pores.

In some embodiments the multiple nozzles may each be connected to a first side a front plate. A second side of the front plate may be mechanically connected to a plurality of pumps, each pump being a part of the spray head. In an example, the spray head may include two, three, four, five, or six pumps. In some embodiments, the pumps may be reciprocating piston pumps. Each of the pumps may include a proximal and a distal end.

The proximal end of each pump may be mechanically connected to a back pressure plate. More specifically, the back pressure plate may be pressure locked over the proximal end of each of the pumps. Additionally, the back pressure plate may include multiple orifices. In an example, the back pressure plate may include the same number of orifices as there are pumps in the spray head. Each pump may be slidably inserted through an orifice within the back pressure plate. In some embodiments, the back pressure plate may be triangular in shape although other shapes are within the scope of the disclosure.

One or more connectors may be disposed around each orifice within the back pressure plate. Each connector may be configured to reversibly connect the back pressure plate to a proximal end of one of the pumps. In an example, the connectors may be clips. As will be described below, when any one of the nozzles is in the “on” position, the adjacent pump and the back pressure plate move toward the front plate. There is little or no pressure on these connectors and, consequently, they do not disengage the proximal end of the pump from the back pressure plate. Conversely, when the nozzle is in an “off” position, the flow-through pressure through the pump is blocked. The piston within the adjacent pump is unable to move and the pump remains stationary. The back pressure plate moves toward the front plate and negative pressure is applied to the connectors. The connectors release the proximal end of the stationary pump from the back pressure plate. Each of the pumps is inserted through an orifice in the back pressure plate. The back pressure plate slides along the length of the stationary pump as the back pressure plate moves toward the front plate.

The spray head may include a single trigger which may actuate one or more of the pumps when the pump is in fluid connection with a nozzle that is in the “on” position. The trigger may be in connection with the back pressure plate through a trigger pump rod.

The spray head may include a plurality of hoses. Each hose may be in fluid communication with one of the pumps and with one of the nozzles. Each hose may extend downward into one of the containers. The hoses may be connected to the pumps with tube fittings as is known in the art. The spray head may include a pump housing which encloses the pumps, front plate, back pressure plate, connectors, and part of each of the hoses.

In another embodiment of the spray head, the spray head housing may include a laterally moveable selector switch indicator. This part may be moved laterally to allow the user to indicate which container he or she wishes to dispense fluid from. In some embodiments, the selector switch indicator may be disposed on the top side of the spray head.

In some embodiments, the spray head housing may include a plurality of selector switch positions into which the selector switch indicator may rest or be inserted. These selector switch positions may hold the selector switch indicator in the desired position until the user desires to change it.

A selector switch arm may be mechanically connected to the selector switch indicator. In some embodiments, selector switch indicator may be positioned on a top side of the spray head and the selector switch arm may extend downward along a rear side of the spray head. In some embodiments, the selector switch arm may be positioned at approximately a 45 degree angle relative to the selector switch indicator. The selector switch arm may include a first and a second end and connect to the selector switch indicator at the first end. The selector switch arm may include a pivot point at its second end where the selector switch arm pivots around a selector switch pivot point when a user moves the selector switch indicator between selector switch positions.

In this embodiment, the spray head may include a rotatable pump carriage which, in some embodiments, may include an arc-shaped housing. The rotatable pump carriage may be connected to a pump carriage pivot axle which may be in mechanical connection with a connector. The connector may include or consist of a rod which extends from the second end of the selector switch arm at one end of the rod and to the pump carriage pivot axle at the opposite end of the rod. In some embodiments, the connector extends from the second end of the selector switch arm at approximately a 45 degree angle (perpendicular) relative to the selector switch arm.

A plurality of pumps may be enclosed within the rotatable pump carriage. The pumps may be of any type described elsewhere herein. The plurality of pumps may be moved as the rotatable pump carriage rotates. In some embodiments, the pump which is disposed in a central position and in alignment with a fluid dispenser will be the pump which is actuated according to the mechanism described below.

The spray pump head may further include a plurality of tubes. Each tube may extend from one of the plurality of pumps on a proximal end of the tube and include a nozzle end on a distal end of the tube. The spray pump head may include a fluid dispenser which may include a plurality of orifices. Each nozzle end may be in fluid communication with an orifice in the fluid dispenser and fluid may pass through the orifice when its associated pump is actuated. In some embodiments, the fluid dispenser may be located on a front side of the spray pump head.

Similar to the previously described embodiment, each pump may be in fluid communication with a single hose. Each hose may extend from one of the plurality of pumps into one of the plurality of containers. Consequently, when an individual pump is actuated, its associated hose draws fluid from the container into which the hose extends.

Similar to the previous embodiment, this embodiment of the spray head may include a single trigger which may be in reversible mechanical connection with one of the plurality of pumps at any one time. A trigger pump actuator arm may include two ends and be mechanically connected to the trigger at one end and to one of the plurality of pumps at the other end. Consequently, when a user squeezes the trigger, the trigger pump actuator arm applies pressure to one of the pumps and actuates that pump. In some embodiments, the trigger and trigger pump actuator arm are mechanically connected to the pump that is in a central position relative to the remainder of the plurality of pumps and to the fluid dispenser.

In some embodiments, the pluralities of parts of the spray head referenced herein include two, three, four, or five of these parts. In some embodiments, the pluralities of parts of the spray head referenced herein include three of each part. For example, the spray head may have three pumps, three hoses, three tubes, three nozzle ends, and three orifices. In this example, the spray head may be connected to three reversibly connectable containers.

In any embodiment of the spray head, a spray handle may be disposed between the spray head and a container release housing. The spray handle may be shaped such that a user may comfortably wrap his or her fingers around the spray handle during use. The spray handle may include an upper end and a lower end. The upper end of the spray handle may be connected to the spray head and the lower end of the spray handle may be connected to the container release mechanism.

The container release mechanism may include a container release housing which may be reversibly connected to the top rim of each of the multiple containers. The top rim may define an opening on each of the containers. The container release housing may include a plurality of orifices which are at least partially defined by a plurality of walls. A lower edge of each wall may include a lip which may partially define one of a plurality of orifices. A container may be pushed upward into each orifice and snap into place as the top rim of the container moves over the lip. The container release mechanism may also include a plurality of release clips each of which may also partially define one of the orifices. Each release clip may similarly snap over the top rim of one of the containers.

The container release mechanism may include a plurality of push buttons each of which causes the release of one the plurality of containers when actuated. In an example, each push button may be in mechanical connection with a release bar which includes a first end and a second end. When a user squeezes the push button inward, the push button may apply inward pressure to the first end of the release bar. The second end of the release bar may apply pressure to a release clip within the container release housing which may partially define an orifice through which a container is inserted. The pressure may push the release clip outward which increases the size of the orifice allowing the container to slide out of the orifice. A spring which extends over each hose may decompress providing additional pressure to push the container out of the orifice.

Referring now to the drawings, FIG. 1 illustrates bottle 100 which is an embodiment of the disclosure. Bottle 100 is a triple-nozzle spray bottle and includes three containers, containers 110a, 110b, and 110c. Bottle 100 further includes finger indentations 125a, 125b, and 125c to which a user may apply his or her fingers during use of bottle 100 and thumb indention 120a to which a user may apply his or her thumb during use of bottle 100. Other finger indentations are present in this embodiment but not visible in this view. Thumb indentions 120b and 120c are present in this embodiment. and not visible in this view. Thumb indentations 120b and 120c are shown in FIGS. 2 and 5. In this embodiment, finger indentations 125a, 125b, and 125c and thumb indention 120a include ridges which may aid in gripping and workflow during use of bottle 100. Container release housing 130 is in connection with the tops of containers 110a, 110b, and 110c and includes push buttons 140a and 140b, shown in FIGS. 1 and 140c which is hidden in this view but visible in FIG. 2. When a user pushes any of push buttons 140a, 140b, or 140c, a spring-loaded mechanism ejects the adjacent container (one of containers 110a, 110b, and 110c). The user may refill or replace the ejected container with another container. Thus, it will be appreciated that container 140a, 140b, and 140c are interchangeable and easily replaced or refilled.

Spray handle 150 extends upward from container release housing 130 and connects the container release housing 130 to spray head housing 210. A user may wrap his or her fingers around spray handle 150 during use of bottle 100. Spray head housing 210 includes nozzles 170a, 170b, and 170c which dispense the fluids which may be housed in containers 110a, 110b, and 110c respectively. As discussed elsewhere herein, each of nozzles 170a, 170b, and 170c may be actuated or blocked at any given time to dispense any combination of fluids in containers 110a, 110b, and 110c. A user may dispense fluids from bottle 100 by squeezing trigger 180 which extends below spray head housing 210.

FIG. 2 illustrates bottle 100 of FIG. 1 and further illustrates a cross-sectional view of the spray handle and spray head. The spray head includes a pump mechanism which is within spray head housing 210. Each of containers 110a, 110b, and 110c is in fluid communication with a pump. In this embodiment, there are three pumps, pumps 220a, 220b, and 220c. Pump 210c is not visible in this view but first presented in FIG. 3A. It will be appreciated that a multi-nozzle spray bottle according to the disclosure may have a different number of containers and, accordingly, the same number of pumps. Pumps 220a, 220b, and 220c each include a proximal end and a distal end. Proximal end 225c and distal end 227c of pump 220c are shown. Proximal and distal ends of pump 220a are not labeled for purposes of clarity.

Proximal end 225c of pump 220c, as well as the proximal ends of the other pumps, are in mechanical connection with back pressure plate 230 and may be reversible attached through connectors. In some embodiments, the connectors may be clips as illustrated in FIG. 7. In this embodiment, back pressure plate 230 is triangular-shaped although one of skill in the art will appreciate that other shapes are within the scope of the disclosure. Back pressure plate 230 may pressure lock over the proximal end of each of each of pumps 220a, 220b, and 220c. In this position, all three of pumps 220a, 220b, and 220c may actuate when trigger 180 is actuated, thus causing fluid from all three of containers 110a, 110b, and 110c to move through the pump mechanism and out one of nozzles 170a, 170b, or 170c. Hoses 240a, 240b, and 240c extend from the proximal end of each of pumps 220a, 220b, and 220c respectively into one of containers 110a, 110b, and 110c. When one or more of pumps 220a, 220b, and 220c is actuated, fluid is drawn from the corresponding container and into the corresponding pump. Fluid drawn from one or more of containers 110a, 110b, and 110c is then dispensed out through one or more of nozzles 170a, 170b, or 170c respectively. Each of nozzles 170a, 170b, and 170c may include one or more of a plain-orifice nozzle, a shaped-orifice nozzle, a surface-impingement single-fluid nozzle, a spiral spray nozzle, a pressure-swirl single-fluid spray nozzle, a spillback nozzle, a solid-cone single-fluid nozzle, or any other single-fluid nozzle known in the art.

FIGS. 3A and 3B illustrate a close-up view of an embodiment of the pump mechanism. In FIG. 3A, all three of pumps 220a, 220b, and 220c are in an “on” position in which all three of nozzles 170a, 170b, and 170c are open and ready to dispense fluid. Nozzles 170a, 170b, and 170c are in mechanical connection with a first side of front plate 320. Additionally, distal end 227c of pump 220c, as well as the distal ends of pumps 220a and 220b, are in mechanical connection with a second side of front plate 320 which is opposite the side in mechanical connection with nozzles 170a, 170b, and 170c.

Back pressure plate 230 includes a plurality of orifices. The proximal end of each of pumps 220a, 220b, and 220c is inserted into one of the plurality of orifices and, when the connectors are engaged, the piston pumps move toward front plate 320 in response to pressure from back pressure plate 230. Tube fitting 310c (not visible in this view) connects the proximal end 227c of pump 220c to hose 240c. Likewise, tube fittings 310a, and 310b connect the proximal ends of pumps 220a and 220b respectively to hoses 240a and 240b respectively. In response to the flow-through pressure created by actuating all three pumps, fluid may be drawn through hoses 240a, 240b, and 240c, through the pump mechanism and out through nozzles 170a, 170b, and 170c.

In FIG. 3B, nozzle 170a has been turned to an “off” position which blocks the flow-through pressure and thereby blocks the flow of fluid through the sections of the pump mechanism which are in fluid communication with nozzle 170a. The connectors which reversibly connect back pressure plate 230 to proximal end 225a of pump 220a have been disengaged. Consequently, when trigger 180 is actuated and back pressure plate 230, moves toward front plate 320, pump 220a does not move toward front plate 320 along with pumps 220b and 220c. Rather, back pressure plate 230 moves lengthwise along pump 220a toward its distal end 227a as pump 220a passes through an orifice in back pressure plate 230. While pumps 220b and 220c move toward front plate 320 drawing fluid through hoses 240b and 240c, pump 220a remains relatively motionless and no fluid moves through hose 240a.

FIG. 4 illustrates a close up view of a container release mechanism which may be included in an embodiment of the disclosed multi-nozzle multi-container fluid spray device. Container 410a is also shown which is an embodiment of one of a plurality of disposable and/or replaceable containers which may be included in an embodiment of the disclosed multi-nozzle multi-container fluid spray device.

Container release housing 130 houses parts which function to reversibly connect a spray handle (in this embodiment, spray handle 150 originally presented in FIG. 1) to the plurality of containers which includes container 410a. Container release housing 130 includes threaded locking ring 420 which connects container release housing 130 to spray handle 150. Lip 422a and container clip 429a at least partially define one of a plurality of orifices. Top rim 423a of container 410a may be pushed through the orifice and beyond lip 422a and container clip 429a. Lip 422a and container clip 429a may then snap back in place securing the top rim 423a above lip 422a and container clip 429a.

Container release housing 130 also includes push button 140a which is in mechanical connection with release bar 425a. Likewise, push button 140b is in mechanical connection with release bar 425b which, in turn, is in mechanical connection with container clip 429b. In summary, each push button on the disclosed device may be in mechanical connection with a release bar and a container may be secured by sliding a top rim of a container over an associated lip and container clip. An example of a mechanism through which container 410a may be inserted and released is described below. A container may be released by actuating push button 140b when corresponding parts participate in the same mechanism.

A container clip holds each container in place by clipping under the top rim of each container. FIG. 4 shows container clip 429a which may help to secure container 410a when container 410a is inserted into the container release mechanism. As shown, container clip 429a compresses container ejector spring 450a. When container 410a is inserted into the container release mechanism, container clip 429a may slip under top rim 423a of container 410a at the inner most section of top rim 423a. The opposite side of top rim 423a may also slip under lip 422a. Container ejector spring 450 continues to be compressed and applies pressure to seal 430a which helps to secure seal 430a to container 410a.

When a user desires to release or replace container 410a, the user may squeeze push button 140a inward which applies inward pressure to a first end of release bar 425a. Push button 140a thereby moves from a first position to a second position (left to right as shown in FIG. 4) and causes release bar 425a to move from a first position to a second position (also left to right as shown in FIG. 4). The second end of release bar 425a applies lateral pressure to container clip 429a. Container clip 429a releases ejector spring 450a which extends downward pushing container 410a downward, thus ejecting container 410a.

Container 410a includes seal 430a over the opening of container 410a. Seal 430a includes hose receptacle 440a. When container 410a is snapped into container release housing 130 as described above, hose 240a may insert through hose receptacle 440a and thus descend into container 410a. Ejector spring 450a slides around tube 240a. When container 410a is inserted into the container release mechanism, ejector spring 450a is compressed and aids in securing top rim 423a of container 410a tightly against seal 430a.

FIG. 5 illustrates an exploded view of three containers, containers 410a, 410b, and 410c, which may be included in an embodiment of the disclosed device. FIG. 5 includes container 410a, part of which was originally presented in FIG. 4. Containers 410b and 410c are similar or identical to container 410a.

As shown in FIG. 5, containers 410a, 410b, and 410c may be separated from each other. Container 410a includes seal 430a and hose receptacle 440a, container 410b include seal 430b and hose receptacle 440b, and container 410c includes seal 430c and hose receptacle 440c. Thumb indentations 120a and 120b as well as finger indentations 125a and 125b are visible in this view. Male notch 510 and female notch 520 are shown on container 410c. While not visible, containers 410a and 410b also include a male notch and a female notch. Male notch 510 on container 410a may insert into a female notch on containers 410b and 410c. Likewise, the male notches on containers 410b and 410c may insert into female notch 520 on container 410a.

FIG. 6A illustrates a pump mechanism being inserted into three containers which have been connected to each other. The pump housing and container release housing are not shown so that the viewer may visualize the parts of the pump mechanism. The pump mechanism of FIG. 6A is as shown in FIGS. 3A and 3B. Trigger 180 is in mechanical connection with trigger pump rod 620 which, in turn is in mechanical communication with back pressure plate 230. Trigger pump rod 620 pulls back pressure plate 230 forward toward front plate 320 when trigger 180 is engaged. Hoses 240a, 240b, and 240c extend into containers 410a, 410b, and 410c respectively. Each of hoses 240a, 240b, and 240c insert into hose receptacles 440a, 440b, and 440c respectively as originally presented in FIG. 4.

FIG. 6B is a close-up view of hoses 240a, 240b, and 240c entering three combined containers through hose receptacles 440a, 440b, and 440c respectively as illustrated in FIG. 5. Ejector spring 450c is shown extending over hose 240c.

FIG. 7 shows the trigger pump mechanism within a spray head according to an embodiment of the disclosure. Trigger 180 is in mechanical connection with trigger pump rod 620 which, in turn, is connected to connecting pivot 630. Connecting pivot 630 inserts into a slot on back pressure plate 230 and may pivot within its slot to allow for movement but still maintain a constant connection with back pressure plate 230. This mechanism may prevent slippage and possible catching or other types of malfunction when trigger 180 is actuated and pump rod 620 applies pressure to back pressure plate 230.

Pump clips secure each of pumps 220a, 220b, and 220c to back pressure plate 230. FIG. 7 shows pump clip 710c in connection with proximal end 225c of pump 220c. Similarly, pump clip 710a is in connection with pump 220a. Each pump clip holds its corresponding pump in an engaged position when the pump is being activated. When one or more of nozzles 170a, 170b, or 170c is turned to the “off” position, the flow-through pressure to the corresponding pump is blocked. The pump clips in connection with the corresponding pump are released when trigger 180 is actuated and the pump clips are allowed to disengage from the corresponding pump. Back pressure plate 230 is free to move over the corresponding pump which remains stationary. This mechanism provides full flexibility and customization of the nozzle spray settings.

FIG. 8 illustrates the mechanism through which back pressure plate 230 returns to its starting position after trigger 180 has been actuated in a situation in which all three of nozzles 170a, 170b, and 170c are turned to the “off” position. Pump 220b with its proximal end 225b and distal end 227b are shown. Pump 220c is omitted for purposes of clarity. When all three of nozzles 170a, 170b, and 170c are turned to the “off” position, the flow-through pressure through pumps 210a, 210b, and 210c is blocked. When trigger 180 is actuated, the trigger pump mechanism described above and illustrated in FIG. 7 moves back pressure plate 230 forward toward front plate 320. As it moves, back pressure plate 230 compresses return spring 640 creating tension. When trigger 180 is disengaged, return spring 640 releases the tension and decompresses, thus returning back pressure plate 230 to its starting position.

FIG. 9 illustrates bottle 900 which is a second embodiment of the disclosed spray bottle. The differences between bottle 900 and bottle 100 are mainly found in and within spray head housing 905 and spray head housing 210 respectively. Bottle 900 includes selector switch indicator 910 on the top of spray head housing 905. Selector switch indicator 910 may be moved laterally between three selector switch positions (920a, 920b, and 920c) along the curved axis shown by the double-headed arrow. In this embodiment, selector switch positions 920a-c include slits into which selector switch indicator 910 may insert into. Each of selector switch positions 920a-c connects a different container to its respective pump so that the contents of that container may be delivered through fluid dispenser 940.

FIG. 10 illustrates a rear view of bottle 900. Selector switch indicator 910 is in mechanical connection with selector switch arm 930 (partially visible in FIG. 9) which extends downward along the rear side 1005 of spray head housing 905. Selector switch indicator 910 and selector switch arm 930 are positioned at approximately a 45 degree angle relative to each other. Selector switch arm 930 includes selector switch pivot point 1010. When a user moves selector switch indicator 910 laterally between selector switch positions 920a-c (shown in FIG. 9), selector switch arm 930 pivots at selector switch pivot point 1010, thus moving along an arc defined by selector switch arm slot 1020.

FIG. 11 shows an up close view of the parts within spray head housing 905. As illustrated in FIG. 11, selector switch arm 930 is in connection with connector 1110. In this embodiment, connector 1110 is a bar extending from selector switch arm 930 at approximately a 45 degree angle, although other angles and connector designs known in the art are within the scope of this disclosure. Connector 1110 connects to selector switch arm 930 at the selector arm pivot point 1010 and is in mechanical communication with pump carriage pivot axle 1120. In this embodiment, pump carriage pivot axel 1120 extends downward from and is in mechanical connection with pump carriage 1130.

Pump carriage 1130 of bottle 900 is an arch-shaped housing that cradles pumps 1140a, 1140b, and 1140c and pivots the proper pump into the center position from a left or right side start point so that it can engage trigger 180 at its stationary position. In this embodiment, pump carriage 1130 is covered by pump carriage securing cover plate 1150.

More specifically, when the pump (selected from pumps 1140a-c) that is positioned within the left side of pump carriage 1130 is moved into the center position by moving selector switch indicator 910 to the right most selector switch position, then the left side pump comes into contact with the stationary centered trigger 180.

Conversely, when the pump that is positioned within the right side of pump carriage 1130 is moved into the center position by moving selector switch indicator 910 to the left most selector switch position, the right side pump comes into contact with the stationary centered trigger 180.

While bottle 900 includes three pumps, other embodiments may include two pumps, four pumps, or more than four pumps. In some embodiments, the pumps are standard spray trigger models, market accepted, one-way valve type, that use a reciprocal type leading to the fluid containers, and an expulsion tube leading to the nozzle end.

Each of pumps 1140a-c is potentially activated by a single trigger, trigger 180. Trigger pump actuator arm 1160 is in mechanical connection with trigger 180. When a user squeezes trigger 180, trigger pump actuator arm 1160 applies positive pressure on the pump which is in the centered position and which is in mechanical connection with trigger pump actuator arm 1160. The action that occurs when the user squeezes trigger 180 creates the pressure needed to actuate the center pump according to its function.

When the pump in the centered position relative to trigger pump actuator arm 1160 is actuated, fluid is drawn through one of hoses 240a, 240b, and 240c, whichever is in fluid communication with the pump in the centered position. As in bottle 100, hoses 240a, 240b, and 240c each extend into a separate one of containers 110a, 110b, or 110c (shown in other drawings). When the fluid reaches the pump in the centered position, it continues through one of tubes 1180a, 1180b. or 1180c, each of which is in fluid communication with one of pumps 1140a-c respectively. More specifically, if pump 1140b is in the centered position, fluid from container 110b is drawn through hose 240b into pump 1140b and into tube 1180b.

Tubes 1180a-c are in fluid communication with nozzle ends 1190a-c respectively which are positioned at spray head front 1170. Fluid is dispensed through the nozzle end which is in communication with the tube extending from the pump in the centered position. For example, if pump 1140b is in the centered position, fluid from container 110b will move through hose 240b into pump 1140b, leave pump 1140b through tube 1180b, and then enter nozzle end 1190b.

Each of the nozzle ends 1190a-c are in connection with three way fluid dispenser 940 (shown in FIG. 9) which includes three orifices, each in connection with one of nozzle ends 1190a-c, through which fluid passes. In this embodiment, the three orifices are in close proximity to each other. Consequently, it may appear to a user that there is only a single orifice through which each of the three fluids passes. By delivering a mostly centered spray experience, the friendliness and familiarity of spray bottle known in the art with which the user may be familiar.

FIG. 12 shows a cross section of the spray head and further illustrates the mechanism through which bottle 900 may be used. In FIG. 12, pump 1140b is in the centered position and in mechanical connection with trigger pump actuator arm 1160. Pump 1140b was moved to the centered position when a user rotated selector switch indicator 910 to selector switch position 920b. Selector switch arm 930 was thus rotated at selector switch pivot point 1010 causing connector 1110 to rotate pump carriage 1130 until pump 1140b is in the centered position as described above.

When a user squeezes trigger 180, it rotates around trigger pivot point 1210 and causes trigger pump actuator arm 1160 to apply pressure to pump 1140b at center pump connecting point 1220. This pressure actuates pump 1140b (but not pumps 1140a or 1140c) which draws fluid through hose 240b (but not hoses 240a or 240c). As in the embodiment of bottle 100, hoses 240a-c only extend into their respective containers 110a-c. Consequently, there is no mixing of fluids when the user squeezes trigger 180. The fluid travels from hose 240b into pump 1140b then out of pump 1140b through tube 1180b. The fluid then moves into nozzle end 1190b which is within three way fluid dispenser 940 (shown in FIG. 9).

FIG. 13 shows bottle 900 with a transparent spray head housing 905 making the parts within visible. FIG. 13 further illustrates the spray head as illustrated in FIG. 12 in connection with the three containers, 110a-c. The parts below spray handle 150 may be as described with regard to bottle 100. In FIG. 13, selector switch indicator 910 is rotated to selector switch position 920c. Pump carriage 1130 has been rotated counterclockwise (to the right) according to the mechanism described above to position pump 1140c in the centered position and in connection with trigger pump actuator arm 1160. When a user squeezes trigger 180, it rotates clockwise around trigger pivot point 1210, thus causing trigger pump actuator arm 1160 to apply positive pressure to pump 1140c at center pump connecting point 1220. This pressure actuates pump 1140c causing it to draw fluid from container 110c through hose 240c which extends into container 110c. The fluid passes into pump 1140c and exits through tube 1180c shown in FIG. 11. The fluid then passes through nozzle end 1190c which is in connection with tube 1180c and exits nozzle end 1190c through the orifice in three way fluid dispenser 940 which is in communication with nozzle end 1190c.
