[0044] Figure 14A This is a flowchart of a method using the dispensing apparatus provided in this disclosure; and

[0045] Figure 14B This is the continuation of the flowchart in Figure 14. Detailed Implementation

[0046] The fluid dispensing apparatus according to this disclosure enables rapid fluid mixing of separate solutions prior to dispensing. Among other benefits, this apparatus allows for application to previously unknown and / or unavailable chemical formulations.

[0047] The fluid distribution apparatus according to this disclosure has several specific advantages. First, they do not require orifices to restrict the flow of various fluids. Second, fluid backflow is restricted by the fluid trapped in the flow chamber. Since the entire system is sealed, the fluid can only move forward through the valves and cannot flow backward. Third, the mixing of the first and second fluids occurs in the pump reservoir, and therefore separate mixing devices are not required.

[0048] Turning now to the accompanying drawing, the fluid dispensing device is shown in... Figure 1 and Figure 2 The fluid dispensing device 10 is generally identified by reference numeral 10. It includes a dispensing head 12 selectively coupled to a bottle 200, which in an embodiment may be a two-chamber bottle. The two-chamber bottle 200 includes an opening at the top, namely a two-chamber bottle inlet 202, with a separator between separate openings 202a and 202b leading to a front chamber 204 and a rear chamber 206. The two-chamber bottle 200 also includes a separate opening leading to the front chamber 204, namely a one-chamber bottle inlet 208, such that the front chamber 204 can be accessed independently of the rear chamber 206 (e.g., accessed individually). In a non-limiting embodiment, the front chamber 204 may be filled with water, but without departing from the scope of this disclosure, it is conceivable that the front chamber 204 may be filled with any suitable fluid or compound. The two-chamber bottle 200 includes a cap 210 selectively coupled to the one-chamber bottle inlet 208 to selectively close the one-chamber bottle inlet 208. In one embodiment, the cap seal 212 can be inserted between the cap 210 and the single-chamber bottle inlet 208. It is conceivable to use any suitable means (such as threaded engagement, snap-fit, friction engagement, quarter turn, etc.) to selectively connect the cap 210 to the single-chamber bottle inlet 212.

[0049] Continue to refer to Figure 1 and Figure 2 And refer to other sources Figures 3A to 12 The distribution head 12 includes an outlet section 14 ( Figure 4 and Figure 5AThe outlet section 14 includes a nozzle valve 16, one or more nozzle inserts 18, and nozzles 20. However, without departing from the scope of this disclosure, it is contemplated that the outlet section 14 may include one or more additional components or may omit one or more of the nozzle valve 16, nozzle inserts 18, and nozzles 20. In a non-limiting embodiment, the outlet section 14 includes a water jacket and an aerator. The dispensing head 12 includes a shroud 24 that houses an engine or pump 40 fluidly connected to the outlet section 14. The engine 40 includes an engine block 42, a piston 44 slidably supported within the engine block 42, a biasing element or spring 46 operably coupled to the piston 44, an actuator or trigger handle 48 operably coupled to the engine block 42 and the piston 44, and a flow chamber 70 operably coupled to and in fluid communication with the engine block 42. In an embodiment, the engine 40 includes a retaining clip 50 operably coupled to the engine block 42 and the trigger handle 48. The retaining clip 50 is operably coupled to a portion of the housing 24 and rotatably supports the trigger handle 48 or otherwise reinforces the connection between the engine 40 and the housing 24. In one embodiment, the engine 40 is combined with the flow chamber 70 in a ratchet neck or screw cap 26. The engine 40 and / or the mixing chamber 70 are sealed to the dual-chamber bottle 200 by means of a sealing gasket 28 disposed above both the first draw tube 76 and the second draw tube 80 and a ratchet neck 26 that interacts with the dual-chamber bottle inlet 202.

[0050] Engine block 42 includes piston chamber or reservoir 52, which is configured to slidably receive piston 44. Figure 5A The piston 44 is translatably supported within the reservoir 52 and cooperates with the reservoir 52 to provide a seal or otherwise retain fluid within the reservoir 52. A spring 46 is disposed within the reservoir 52 and inserted between a first end 44a of the piston 44 and an inner wall 52a of the reservoir 52. In this way, the spring 46 biases the piston 44 in a direction away from the inner wall 52a and provides a biasing force or resistance against translation of the piston 44 toward the inner wall 52a. Although generally shown as a compression coil spring, the spring 46 is contemplated as any suitable biasing element, such as, for example, a pneumatic spring, a polymer spring, a Bainckia washer, a tension spring, a leaf spring, etc., without departing from the scope of this disclosure.

[0051] Piston 44 includes or otherwise defines a ball socket 54 that extends from a second end 44b of piston 44 in a direction away from the inner wall 52a of reservoir 52. The ball socket 54 is conceivable to be a separate component connected to piston 44 by any suitable means, or it may be integrally formed with piston 44 (e.g., piston 44 and ball socket 54 formed as a single component). Trigger handle 48 is rotatably supported by engine block 42 and / or retaining clamp 50 and operatively coupled to ball socket 54. As will be described in further detail below, actuation of trigger handle 48 transmits a force from trigger handle 48 to ball socket 54, pushing piston 44 toward the inner wall 52a of reservoir 52. The biasing force of spring 46 prevents piston 44 from translating toward inner wall 52a until the force applied to ball socket 54 exceeds the biasing force of spring 46, at which point continued actuation of trigger handle 48 causes piston 44 to compress spring 46 and translate toward inner wall 52a.

[0052] Continue to refer to Figure 5A and Figure 5B Engine block 42 defines an outlet passage 56 extending between an inlet 56a and an opposite outlet 56b. The outlet passage 56 is operatively coupled to and in fluid communication with an outlet portion 14. In this manner, a nozzle valve 16 can be supported within the outlet 56b of the outlet passage 56 in a translational manner between a first closed position and a second open position, the first closed position preventing air or fluid from flowing through the nozzle 20 and into the outlet passage 56, and the second open position allowing fluid to flow from the outlet passage 56 to the nozzle 20. Engine block 42 defines an inlet passage 58 extending between an inlet 58a and an opposite outlet 58b. The outlet 58b is in fluid communication with the inlet 56a of the outlet passage 56 to allow fluid to flow from the inlet passage 58 into the outlet passage 56. As will be described in further detail below, the inlet 58a of the inlet passage 58 is in fluid communication with the upper chamber 120 of the flow chamber 70. Engine block 42 defines a port 60 ( Figure 5B The port fluidly connects the reservoir 52 to the inlet channel 58. The port 60 is defined at a location where fluid can be selectively discharged from the reservoir 52 into the inlet channel 58 and fluid can be selectively drawn from the inlet channel 58 into the reservoir 52.

[0053] Return to reference Figure 4 And refer to other sources Figures 5B to 7 The flow chamber 70 includes a lower chamber 72, a metering device 100, and an upper chamber 120 operatively connected to the lower chamber 72. The lower chamber 72 includes a first inlet 74 operatively and fluidly connected to a first draw tube 76 and a second inlet 78 operatively and fluidly connected to a second draw tube 80. Figure 4 and Figure 5A The first draw tube 76 can be selectively received in the front bottle chamber 204. Figure 2The first inlet 74 is fluidly connected to the front bottle chamber 204. In one embodiment, the first inlet 74 includes a reflux valve 75. Figure 5C The reflux valve is configured to transition from a first closed position to a second open position. In the first closed position, it prevents fluid from flowing from the lower chamber and returning to the front bottle chamber 204. In the second open position, it allows fluid to flow from the front bottle chamber 204 into the lower chamber 72. In an embodiment, the reflux valve 75 may include a biasing element 79. Figure 10 The biasing element is inserted between the return valve 75 and the upper chamber 120 to bias the return valve 75 to the closed position or otherwise push the return valve to the closed position.

[0054] The second draw tube 80 can be selectively received in the rear bottle chamber 206. Figure 2 Inside, the second inlet 78 is fluidly connected to the rear bottle chamber 206. In an embodiment, a one-way valve or check valve 77 ( Figure 3B , Figure 9A and Figure 9B The device can be operatively coupled to a second draw tube 80 to allow a second fluid to be drawn from the rear chamber 206 into the lower chamber 72 and to prevent fluid from flowing back from the lower chamber 72 into the rear chamber 206. The lower chamber 72 defines an annular boss 82 extending in a direction remote from the second inlet 78 and including a hollow interior or channel 84. The second inlet 78 is in fluid communication with the channel 84 via an orifice 86. The channel 84 defines a first sealing surface 88 whose internal dimensions transition from the internal dimensions of the channel 84 to the internal dimensions of the orifice 86, which are smaller than the internal dimensions of the channel 84. Although generally shown as including a truncated conical profile, it is contemplated that the first sealing surface 88 may include any suitable profile against which the ball 112 of the metering device 100 abuts and forms a seal.

[0055] The metering device 100 includes a metering valve insert 102, a metering chamber 110, and a valve 112. In an embodiment, the valve 112 may be a ball valve. The metering valve insert 102 is disposed within a passage 84 of the lower chamber 72 and includes an inner cavity 104 extending through opposite upper surfaces 102a and lower surfaces 102b. Figure 7 The lower surface 102b of the metering valve insert 102 defines a second sealing surface 106, the internal dimensions of which transition from the internal dimensions of the cavity 104 to the internal dimensions of the channel 84, which are larger than the internal dimensions of the cavity 104. Although generally shown as having a profile complementary to that of the first sealing surface 88, the second sealing surface 106 is contemplated to include any suitable profile that the ball 112 of the metering device 100 can abut against and form a seal.

[0056] Metering chamber 110 is defined between first sealing surface 88 and second sealing surface 106. As can be understood, the volume of metering chamber 110 is defined by the internal dimensions of channel 84 and the distance between first sealing surface 88 and second sealing surface 106. In embodiments, the volume of metering chamber 110 depends on the type of fluid or cleaning solution (e.g., a second fluid) held within rear bottle chamber 206 and the type of desired mixture (e.g., a certain amount of diluent), and is configured to hold a predetermined amount of second fluid. It is conceivable that the volume of metering chamber 110 is determined based on the properties of the second fluid (such as, for example, viscosity and / or density), the internal dimensions and length of each of orifice 86 and cavity 104, and the size, shape, and other characteristics of valve 112.

[0057] A valve 112 (a ball in an exemplary embodiment) is slidably disposed within a metering chamber 110. In this manner, the external dimensions of the ball 112 are equal to or smaller than the internal dimensions of the metering chamber 110, and the internal dimensions of each of the orifice 86 and the cavity 104 are smaller than the external dimensions of the ball 112. The ball 112 is configured to transition between a first position where it abuts the first sealing surface 88 and a second position where it abuts the second sealing surface 106. In this embodiment, the volume of the metering chamber 110 is defined taking into account the volume created by the displacement of the ball 112 to ensure that a desired amount of second fluid is drawn into the metering chamber 110.

[0058] During operation, when ball 112 is set in the first position ( Figure 13A When the second fluid is drawn from the rear chamber 206 into the second draw tube 80 and flows through the inner cavity 104 into the metering chamber 110, the second fluid is allowed to continue to be drawn into the metering chamber 110, causing the second fluid to flow through the orifice 86 and into the lower chamber 72. Further drawing of the second fluid into the metering chamber 110 causes the second fluid to push the ball 112 toward the second sealing surface 106, achieving a seal between the ball 112 and the second sealing surface 106, thereby preventing additional second fluid from flowing through the orifice 86. Figure 13B After a predetermined amount of the second fluid is drawn into reservoir 52 and / or reaches a predetermined pressure within reservoir 52, ball 112 is allowed to fall toward or otherwise translate toward the first sealing surface 88 and abut against the first sealing surface 88 to form a seal. As can be understood, the pressure within mixing chamber 110, in conjunction with the density and / or weight of ball 112, applies force to ball 112 to push ball 112 into sealing surface 88 to prevent or otherwise prevent fluid backflow or backflow through orifice 88 into rear bottle chamber 206. Figure 13CAlthough typically described as a ball, valve 112 can be envisioned as any suitable valve having any suitable shape (such as spherical, rod-shaped, disc-shaped, etc. and / or combinations thereof) capable of translating within the metering chamber and abutting against each of the first sealing surface 88 and the second sealing surface 106 to form a seal. In embodiments, valve 112 may be selected from the group consisting of check valves, ball valves, duckbill valves, and combinations thereof.

[0059] The density of ball 112 is greater than or otherwise greater than the density of the second fluid or dispensing fluid. It is conceivable that the density of ball 112 be determined based on the properties of the second fluid, such as viscosity and / or density. This includes, as can be understood, the speed or rate at which ball 112 translates within metering chamber 110, and the mass of the seal formed by ball 112 against each of the first sealing surface 88 and the second sealing surface 106. It is conceivable that ball 112 be formed of any suitable material that can coexist with the first fluid (e.g., water) and the second fluid. In embodiments, ball 112 may be formed of a material selected from the group consisting of rubber, natural rubber, synthetic rubber, polymers, and combinations thereof. In a non-limiting embodiment, valve 112 is spring-loaded.

[0060] Continue to refer to Figures 4 to 8 Upper chamber 120 and lower chamber 72 cooperate to define entrance chamber 122 ( Figure 5A and Figure 5C The inlet chamber 122 is in fluid communication with the inner cavity 104 of the first inlet 74 and the mixing valve insert 102. In this way, when the trigger handle 48 is actuated, the second fluid is drawn from the second bottle chamber 206 into the metering chamber 110 and into the inlet chamber 122. When the metering device 100 is closed (e.g., the ball 112 abuts the second sealing surface 106), the flow of the second fluid through the metering device 100 is reduced or otherwise stopped, and the first fluid is drawn from the front bottle chamber 204 into the inlet chamber 122.

[0061] The upper chamber 120 defines an orifice 124 that is in fluid communication with the inlet chamber 122 and the inlet passage 58 of the engine block 42. Figure 5A , Figure 5B and Figure 8 The hole 124 defines a recess or countersunk hole 126 adjacent to the entrance channel 58. Figure 8 The recess 126 defines the internal dimensions for slidably receiving the inlet valve or ball 128. Figure 5B ). Recess 126 defines third sealing surface 130 ( Figure 8The internal dimensions of the third sealing surface transition from the internal dimensions of the recess 126 to the internal dimensions of the hole 124, and the internal dimensions of the third sealing surface are smaller than the external dimensions of the ball 128. Although typically shown as including a truncated conical profile, it is conceivable that the third sealing surface 130 may include any suitable profile that the ball 128 abuts against and forms a seal. The third sealing surface 130 is located below the ball 128 or otherwise inserted between the port 60 of the engine block 42 and the inlet chamber 122.

[0062] The inlet 58a of the inlet channel 58 includes a countersunk hole 58c, the internal dimensions of which are complementary to the internal dimensions of the recess 126 of the upper chamber 120. Figure 5B In this way, ball 128 is allowed to translate from recess 126 into countersunk hole 58c. Countersunk hole 58c defines a fourth sealing surface 58d, the internal dimensions of which transition from the internal dimensions of countersunk hole 58c to the internal dimensions of inlet channel 58, the internal dimensions of which are smaller than the external dimensions of ball 128. Although generally shown as having a profile complementary to the profile of third sealing surface 130, it is contemplated that fourth sealing surface 58d includes any suitable profile that ball 128 can abut against and form a seal. Fourth sealing surface 58d is positioned above ball 128 or otherwise inserted between port 60 and inlet 56a of outlet channel 56.

[0063] Ball 128 can transition between a first open position and a second closed position. When ball 128 is in the first open position, ball 128 abuts against the fourth sealing surface 58d to form a seal, allowing fluid to flow through the orifice 124 of the upper chamber 120, through the port 60, and into the reservoir 52, while preventing fluid from flowing through the outlet passage 56. Figure 13A With ball 128 in the second closed position, ball 128 abuts against third sealing surface 130 to form a seal, allowing fluid to flow from reservoir 52 through port 60 and through outlet passage 56 and out through outlet 14, while preventing fluid from flowing into orifice 124 in upper chamber. Figure 13C ).

[0064] Go to Figures 9A to 12 This illustrates another embodiment of the distribution head, which is generally identified by reference numeral 300. Distribution head 300 is substantially similar to distribution head 12; therefore, for the sake of brevity, this document will only describe the differences between them in detail.

[0065] The dispensing head 300 includes a metering valve plate 302 inserted between the upper chamber 120 and the lower chamber 72. Figure 10In an exemplary embodiment, a metering valve plate 302 replaces the metering valve insert 102. The metering valve plate 302 defines a countersunk hole 304 through an upper portion 306, which is in fluid communication with a hole 124 in the upper chamber 120. The metering valve plate 302 defines a first boss 308 extending from a lower portion 310, which is generally aligned with and accommodated within a portion of a passage 84 in the lower chamber 72 to define a metering chamber 110. A through-hole 312 defined in the first boss 308 passes through the upper portion 306 and the lower portion 310, fluidly connecting the metering chamber 110 to the countersunk hole 304 and the hole 124 in the upper chamber 120. A fifth sealing surface 314 is defined on the first boss 308, the internal dimensions of which transition from the internal dimensions of the passage 84 to the internal dimensions of the through-hole 312, the internal dimensions of which are smaller than the external dimensions of the ball 112 of the metering device 100. Although typically shown as having a profile complementary to the profiles of the first sealing surface 88, the second sealing surface 106, the third sealing surface 130 and / or the fourth sealing surface 58d, it is conceivable that the fifth sealing surface 314 may include any suitable profile that the ball 112 can abut against and form a seal.

[0066] The metering valve plate 302 includes a second boss 316 extending from the lower portion 310, which is generally aligned with the first inlet 74. The second boss 316 includes a hole 318 for fluidly connecting the first inlet 74 to the countersunk hole 304. As will be understood, the internal dimensions of the hole 318 may be selected based on the design requirements of the dispensing head 300. A biasing element 79 is inserted between the metering valve plate 302 and the return valve 75 to bias the return valve 75 to or otherwise push it to a closed position. Although typically shown as a compressed helical spring, the biasing element 79 is contemplated to be any suitable biasing element, such as, for example, a polymer spring, a pneumatic spring, a Bainckia washer, a tension spring, etc., and combinations thereof, without departing from the scope of this disclosure. In embodiments, the dispensing head 300 may include a biasing element guide 320 inserted between the mixing valve plate 302 and the return valve 75. The bias element guide 320 includes a hole 322 for receiving or otherwise retaining the bias element 79, thereby preventing the bias element 79 from leaving its place or otherwise becoming misaligned with the return valve 75.

[0067] Dispensing head 300 includes one or more air inlet valves 324 operatively coupled to lower chamber 72. In a non-limiting embodiment, dispensing head 300 includes a first air inlet valve 324 in fluid communication with front chamber 204 and a second air inlet valve 326 in fluid communication with rear chamber 206. Each air inlet valve 324 is substantially similar to each other, therefore, for the sake of brevity, only the first air inlet valve 324 will be described in detail herein. Air inlet valve 324 includes an air inlet valve cover 328 operatively coupled to lower chamber 72. Air inlet valve cover 328 defines an internal cavity 330 and a perforation 332 allowing fluid to flow into and out of the internal cavity 330. Air inlet valve 324 includes a valve 334 and a biasing element 336 received within the internal cavity 330 and inserted between valve 334 and air inlet valve cover 328. As can be understood, the biasing element biases or otherwise actuates valve 334 toward the lower chamber 72 and toward the first closed position to prevent fluid (e.g., a first fluid) from flowing into the lower chamber 72. In operation, air inlet valve 324 allows air to flow into the front chamber 204 and prevents the first fluid from flowing into the lower chamber 72. Valve 334 can be envisioned as any valve configured to prevent fluid backflow, and in embodiments, may be selected from the group consisting of check valves, ball valves, duckbill valves, and combinations thereof. In some embodiments, valve 334 comprises a material selected from the group consisting of rubber, natural rubber, synthetic rubber, polymers, and combinations thereof.

[0068] refer to Figures 13A to 13C During operation, when the actuator or trigger handle 48 returns to its initial unactuated position via the spring 46, the trigger handle 48 pushes or otherwise pulls the piston 44 away from the inner wall 52a of the reservoir 52. Figure 13AWith nozzle valve 16 in the closed position, air is prevented from entering outlet passage 56, allowing for the extraction or otherwise creation of a vacuum within reservoir 52. The vacuum within reservoir 52 causes inlet valve 128 to transition to the open position, where ball 128 seals against fourth sealing surface 58d and port 60 is in fluid communication with upper chamber 120. The vacuum within reservoir 52 draws second fluid from rear bottle chamber 106 into metering chamber 102, causing ball 112 of metering device 100 to begin transitioning from a first position to a second position. The continued vacuum within reservoir 52 draws second fluid from inlet chamber 122 through port 60 into reservoir 52. Further vacuum within reservoir 52 causes ball 112 of metering device 100 to abut against second sealing surface 94 of metering valve insert 90, preventing additional second fluid from flowing into inlet chamber 122, while allowing additional first fluid to be drawn from front bottle chamber into reservoir 52. In this manner, a predetermined amount of second fluid is drawn into reservoir 52 to dilute or otherwise form a desired mixture or dispensing fluid of the first and second fluids. After a predetermined pressure is reached or a predetermined volume of dispensing fluid is received in reservoir 52, the vacuum in reservoir 52 is reduced or otherwise stopped, allowing the return valve 75 to transition to a closed position, thereby preventing fluid flow back into the front chamber 104, and allowing the ball 112 of metering device 100 to transition to a first position, thereby preventing fluid flow back into the second chamber 106. Additionally, ball 128 is allowed to transition from an open position to a closed position, in which ball 128 seals against the third sealing surface 130 and its port is in fluid communication with the outlet passage 56. With the trigger handle 48 returned to the unacted position, the trigger handle 48 can be actuated or otherwise pressed down to push piston 44 toward the inner wall 52a of reservoir 52 and dispense fluid through nozzle 20, thereby allowing the first and second fluids to be sequentially pumped or otherwise drawn into reservoir 52. As will be understood, it is not necessary to set the trigger handle 48 to the unactivated position before actuating it again. Any number of times the above operation can be performed without departing from the scope of this disclosure.

[0069] Go to Figure 14A and Figure 14BThe diagram illustrates a method using a fluid dispensing device, generally identified by reference numeral 1400. The actuator or trigger handle is initially returned to its unactuated position via a spring, and the piston is pushed or otherwise pulled away from the inner wall of the reservoir (step 1402). With the nozzle valve in the closed position, air is prevented from entering the outlet passage, thereby enabling the evacuation or otherwise creation of a vacuum within the reservoir (step 1404). The vacuum within the reservoir causes the inlet valve to transition to the open position and the port to fluid communication with the upper chamber, in which the ball seals against the fourth sealing surface (step 1406). The vacuum within the reservoir draws a second fluid from the rear chamber into the metering chamber (step 1408), causing the ball of the metering device to transition from a first position to a second position (step 1410). The vacuum within the reservoir continues to draw the second fluid from the inlet chamber through the port and into the reservoir (step 1412). The vacuum within the reservoir is further evacuated so that the ball of the metering device abuts the second sealing surface of the metering valve insert, and prevents additional second fluid from flowing into the inlet chamber (step 1414), while additional first fluid is drawn from the front chamber and into reservoir 52 (step 1416). After a predetermined pressure is reached in the reservoir or a predetermined volume of dispensing fluid is received in the reservoir (step 1418), the vacuum in the reservoir is reduced or otherwise stopped (step 1420), allowing the reflux valve to transition to the closed position, thereby preventing fluid from flowing back into the front chamber, and allowing the ball of the metering device to transition to the first position, thereby preventing fluid from flowing back into the second chamber (step 1422). As can be understood, if the predetermined pressure or predetermined volume of dispensing fluid is not reached, the first fluid continues to be drawn into the reservoir (step 1416). If the predetermined pressure or volume of dispensing fluid is reached, the ball of the inlet valve is allowed to transition from the open position to the closed position, in which the ball of the inlet valve seals against the third sealing surface and the port is in fluid communication with the outlet passage (step 1424). With the trigger handle returned to the unacted position, the trigger handle can be actuated or otherwise pressed down to push the piston toward the inner wall of the reservoir and dispense fluid through the nozzle (step 1426), so that the first and second fluids can be sequentially pumped or otherwise drawn into the reservoir. It will be understood that the trigger handle need not be placed in the unacted position before being actuated again. Without departing from the scope of this disclosure, it is conceivable that the above operations can be performed any number of times.

[0073] In some embodiments, the fluid dispensing device 10 includes at least two metering devices. In some embodiments, the fluid dispensing device includes at least three metering devices. In some embodiments, the fluid dispensing device includes more than three metering devices.

[0074] In some embodiments, the fluid dispensing device 10 is configured to mix and meter at least two fluids. In some embodiments, the fluid dispensing device 10 is configured to mix and meter at least three fluids. In some embodiments, the fluid dispensing device 10 is configured to mix and meter more than three fluids.

[0075] In some embodiments, at least one of the first inlet 74 and / or the second inlet 78 of the flow chamber 70 includes a valve configured to prevent fluid backflow. In some embodiments, only the first inlet 74 of the flow chamber 70 includes a valve configured to prevent fluid backflow. In some embodiments, only the second inlet 78 of the flow chamber includes a valve configured to prevent fluid backflow. In some embodiments, both the first inlet 74 and the second inlet 78 of the flow chamber 70 include valves configured to prevent fluid backflow.

[0076] In some embodiments, at least one of the first inlet 74 and / or the second inlet 78 of the flow chamber 70 does not include a valve configured to prevent fluid backflow.

[0077] The dual-chamber bottle 200 can be configured relative to the dispensing head 12 in a manner known in the art. In some embodiments, the dual-chamber bottle 200 is mechanically coupled to the dispensing head 12 by means of an accessory selected from a group consisting of snap-fit ​​fittings, screw fittings, and combinations thereof.

[0078] actuator

[0079] Typically, the trigger handle or actuator 48 can be any suitable actuation mechanism or means known in the art. The trigger handle or actuator 48 enables the dispensing of fluid by actuating a pump. In some embodiments, the actuator 48 is a trigger. In some embodiments, the actuator 48 is selected from the group consisting of: trigger actuators, mechanical triggers, electrical triggers, trigger engines, pull triggers, push triggers, squeeze triggers, pump actuators, squeeze bottles, and combinations thereof.

[0080] Extraction tube

[0081] In many embodiments, the draw tubes 76, 80 can be used with the fluid dispensing device 10 in various combinations. In some embodiments, the draw tubes 76, 80 have an inner diameter that is easily determined by their coloring. In some embodiments, the draw tubes 76, 80 do not have an inner diameter that is easily determined by their coloring.

[0082] In some embodiments, the fluid dispensing device 10 does not include one or more draw tubes 76, 78. In some embodiments, the fluid dispensing device 10 includes one or more draw tubes 76, 78 integrally formed with the dual-chamber bottle 200. In some embodiments, the fluid dispensing device 10 includes a collapsible bag (not shown) located inside the dual-chamber bottle 200.

[0083] In some embodiments, the draw tubes 76, 80 facilitate identification and installation of the variable inner diameter draw tubes 76, 80. The upper portions of the draw tubes 76, 80 may be colored and / or dyed, including giving draw tubes 76, 80 with different inner diameters different colors and / or dyes. In some embodiments, a first fluid is configured to flow through a first draw tube 76, and a second fluid is configured to flow through a second draw tube 80.

[0084] Coloring of the draw tubes 76 and 80 is particularly advantageous during manufacturing. In some embodiments, the draw tubes 76 and 80 can be selected and assembled based on their coloring, which corresponds to their inner diameter. In some embodiments, the combination of a constant outer diameter and a variable inner diameter based on coloring of the draw tubes 76 and 80 provides adaptability due to a single-size design. This approach reduces manufacturing costs and time constraints.

[0085] In some embodiments, the coloring of the dispensing tubes 76, 80 can be visualized during manufacturing using human vision and / or machine vision to ensure that the dispensing tubes 76, 80 are fully inserted. This coloring enables better quality assurance during production by providing means and systems to ensure complete dispensing tube insertion. For example, the upper portion of the dispensing tubes 76, 80 can be colored red, and the red color will no longer be visible when the dispensing tubes 76, 80 are fully inserted into the dispensing device 10.

[0086] In many embodiments, the diameters of the first draw tube 76 and the second draw tube 80 can be any useful diameter known in the art. In some embodiments, the first draw tube 76 and the second draw tube 80 have substantially similar inner diameters. In some embodiments, the substantially similar inner diameters differ by no more than 25%. In some embodiments, the substantially similar inner diameters differ by no more than 10%. In some embodiments, the substantially similar inner diameters differ by no more than 5%. In some embodiments, the substantially similar inner diameters differ by no more than 1%. This aspect enables the fluid dispensing device 10 to be used for a wide range of chemical formulations, including reactive and / or concentrated formulations.

[0087] In some embodiments, the first suction tube 76 and the second suction tube 80 have the same or similar outer diameters.

[0088] In some embodiments, at least one of the first suction tube 76 and the second suction tube 80 has a diameter of at least 0.5 mm, 0.615 mm, 0.665 mm, 0.775 mm, 0.825 mm, 0.9 mm, 1 mm, 1.5 mm or 2 mm.

[0089] In some embodiments, the diameter of the first draw tube 76 is larger than that of the second draw tube 80. In some embodiments, the ratio of the diameter of the first draw tube 76 to the diameter of the second draw tube 80 is at least 1:1, 2:1, 3:1, 4:1, 5:1, 6:1, 7:1, 8:1, 9:1 or 10:1.

[0090] The fluid dispensing device 10 is capable of dispensing multiple fluids. In some embodiments, the viscosity of the first fluid is different from the viscosity of the second fluid. In some embodiments, the viscosity of the first fluid is the same as the viscosity of the second fluid.

[0091] The fluid dispensing device 10 is capable of dispensing a wide range of chemical agents known in the art. In some embodiments, the fluid dispensing device 10 is configured to dispense agents selected from the group consisting of: reactive agents, concentrated agents, cleaning agents, cleaning agents requiring an oxidative reaction, agents for removing organic and / or protein stains, agents for removing mold stains, oxidizing disinfectant agents, agents containing organic acids, agents containing peracetic acid, diluents, solvents, and combinations thereof. In some embodiments, the fluid dispensing device 10 is configured to dispense agents selected from the group consisting of: detergents, household cleaners, bathroom cleaners, kitchen cleaners, glass cleaners, stain removers, and combinations thereof.

[0092] In some embodiments, the fluid dispensing device 10 is configured to combine a colorless fluid and a colored fluid. In some embodiments, the colorless fluid and the colored fluid do not react chemically. In some embodiments, the colored fluid is replaceable.

[0093] Typically, the fluid dispensing device 10 is capable of combining chemical components that need to be separated before application. For example, the chemical components may react with each other. This combination of reactive chemicals enables the use of novel reactive formulations, such as cleaning and disinfecting agents, that can be superior to conventional cleaning and disinfecting products.

[0094] As another example, it may be desirable to dilute the chemical concentrate before dispensing. In these embodiments, the fluid dispensing device 10 can be used to apply the concentrated formulation (such as a concentrated cleaning agent), where the user only needs to add a diluent (e.g., water) to the refillable side (e.g., the first chamber 204 of a separator bottle (e.g., a dual-chamber bottle 200)). In some embodiments, the fluid dispensing device 10 draws a higher proportion of water from one compartment of the separator bottle than the proportion of cleaning solution in the opposite compartment of the same separator bottle. This operating principle depletes the water compartment faster than the cleaning concentrate side of the bottle. The water portion of the bottle can then be refilled with tap water without the user needing to handle any cleaning chemicals. In this way, the disadvantages of most conventional cleaning concentrate technologies are overcome.

[0095] In many embodiments, the first fluid and the second fluid can be combined in any suitable ratio. In some embodiments, the first fluid and the second fluid are combined in a ratio ranging from about 20:1 to about 1:20. In some embodiments, the first fluid and the second fluid are combined in a ratio within the range of about 20:1, about 19:1, about 18:1, about 17:1, about 16:1, about 15:1, about 14:1, about 13:1, about 12:1, about 11:1, about 10:1, about 9:1, about 8:1, about 7:1, about 6:1, about 5:1, about 4:1, about 3:1, about 2:1, about 1:2, about 1:3, about 1:4, about 1:5, about 1:6, about 1:7, about 1:8, about 1:9, about 1:10, about 1:11, about 1:12, about 1:13, about 1:13, about 1:14, about 1:15, about 1:15, about 1:16, about 1:17, about 1:18, about 1:19, or about 1:20.

[0096] bottle

[0097] The bottle is configured to contain multiple separate solutions. In some embodiments, the bottle is a separatory bottle with two separate chambers. In some embodiments, the bottle is a separatory bottle with more than two separate chambers. In some embodiments, at least one chamber is individually accessible. In some embodiments, each chamber is individually accessible.

[0098] In some implementations, at least one chamber is removable from the bottle.

[0099] In some embodiments, the two separate chambers may be in the form of separate bottles. In these embodiments, the reference to a bottle refers to a combination of two separate bottles.

[0100] In some embodiments, the bottle includes multiple chambers. The multiple chambers may include two, three, four, five, six, or more than six chambers. Each of the multiple chambers may have any suitable size (e.g., large or small). Each of the multiple chambers may be permanent, temporary, replaceable, and / or refillable. Each of the multiple chambers contains a different fluid. The fluid dispensing device 10 is capable of mixing each of the different fluids at a desired ratio.

[0101] In some embodiments, the fluid dispensing device 10 is configured to mix and meter at least two fluids. In some embodiments, the fluid dispensing device 10 is configured to mix and meter at least three fluids. In some embodiments, the fluid dispensing device 10 is configured to mix and meter more than three fluids. In these embodiments, each fluid may be contained in one or more containers. In some embodiments, each fluid is in a separate container.

[0102] In some embodiments, the bottle can be rotated relative to the dispensing head 12. In these embodiments, rotating the bottle relative to the dispensing head 12 can change which chamber is aligned with the metering device housed within the dispensing head 12. Therefore, the mixing ratio of the fluids housed in the chambers can be changed. In the case of two fluids, the mixing ratio can be reversed (e.g., a 1:3 detergent to water mixing ratio can be reversed to a 3:1 detergent to water ratio).

[0103] In some implementations, at least one of the multiple chambers is configured to be sealed and filled by the manufacturer in a single operation.

[0104] In some embodiments, at least one of the multiple chambers is configured to be refilled once empty. The refillable chamber may be configured to contain water. In these embodiments, the refillable chamber can be repeatedly refilled until the other chambers are empty and further mixing cannot occur.

[0105] In some implementations, at least one of the multiple chambers includes water.

[0106] The bottle is capable of containing a wide range of chemical formulations known in the art. In some embodiments, the bottle is configured to contain formulations selected from the group consisting of: reactive formulations, concentrated formulations, cleaning formulations, cleaning formulations requiring an oxidative reaction, formulations for removing organic and / or protein stains, formulations for removing mold stains, oxidizing disinfectant formulations, formulations containing organic acids, formulations containing peracetic acid, diluents, solvents, and combinations thereof. In some embodiments, the bottle is configured to contain formulations selected from the group consisting of: detergents, household cleaners, bathroom cleaners, kitchen cleaners, glass cleaners, stain removers, and combinations thereof.

[0172] This written description uses examples to illustrate this disclosure, including best practices, and also enables any person skilled in the art to practice this disclosure, including making and using any composition or system and performing any included methods. The patentable scope of this disclosure is defined by the claims, but may include other examples that would occur to a person skilled in the art. Such other examples are intended to be within the scope of the claims if they have elements that are not different from the wording of the claims, or if they include equivalent elements that are not substantially different from the wording of the claims.

[0173] As used herein, the terms “comprising,” “including,” “containing,” “possessing,” “holding,” “having,” “containing,” “characteristics,” or any other variation thereof are intended to cover non-exclusive inclusion, but are subject to any limitations expressly indicated. For example, a composition, mixture, process, or method that includes the listed elements is not necessarily limited to those elements, but may also include other elements not expressly listed or inherent to the composition, mixture, process, or method.

[0174] The transitional phrase "composed of..." excludes any unspecified elements, steps, or ingredients. If present in a claim, this would exclude materials other than impurities typically associated with it. When the phrase "composed of..." appears in a clause of the body of a claim, rather than immediately following the preamble, it limits only the elements set forth in that claim; other elements are not excluded from the entire claim.

[0175] The transitional phrase "consistently of..." is used to define a composition or method that includes materials, steps, features, components, or elements other than those literally disclosed, provided that such additional materials, steps, features, components, or elements do not materially affect the essential and novel features of the claimed utility model. The term "consistently of..." falls between "comprising" and "composed of...".

[0176] If a utility model or part thereof is defined by an open-ended term such as “comprising”, it should be readily understood (unless otherwise stated) that the specification should be interpreted as also using the terms “consistently composed of” or “comprises of” to describe such a utility model.

[0177] Furthermore, unless explicitly stated otherwise, "or" refers to an inclusive "or," not an exclusive "or." For example, condition A or B is satisfied by any of the following conditions: A is true (or exists) and B is false (or does not exist); A is false (or does not exist) and B is true (or exists); and both A and B are true (or exist).

[0178] Furthermore, the indefinite articles “a” and “an” preceding the elements or components of this invention are intended to be unrestricted in terms of the number of instances (i.e., the number of times) of the elements or components. Thus, “a” or “an” will be interpreted as including one or at least one, and the singular form of an element or component also includes the plural, unless the number clearly refers to the singular.

[0179] This application claims the benefit and priority of U.S. Provisional Patent Application Serial No. 63 / 537,602, filed September 11, 2023, the disclosure of which is incorporated herein by reference in its entirety.

[0180] As used in this article, the term “about” means plus or minus 10% of the value.
