[0021] The foregoing aspects and many associated advantages of the present invention will be more easily understood as they are better understood with reference to the detailed description that follows, when taken in conjunction with the accompanying drawings. Detailed description

[0022] The detailed description below, in conjunction with the accompanying drawings on which the same numbers refer to the same elements, is intended to describe various embodiments of the disclosed subject matter and should not be interpreted as representing the only possible embodiments. The embodiments described in this disclosure are provided solely by way of example or illustration and should not necessarily be construed as preferred or advantageous over other embodiments. The illustrative examples provided herein are not intended to be exhaustive or to limit the claimed subject matter to the specific forms disclosed.

[0023] This disclosure relates, in general, to a flow verification system for a peristaltic pump system and an improved method for verifying flow through the peristaltic pump system. Peristaltic pumps can be used to move non-gaseous fluids through a fluidic system. Examples of non-gaseous fluids include liquids, solutions, colloids, suspensions, mixtures, and the like. Peristaltic pumps typically contain a circular casing, a number of rollers attached to the outer circumference of a motor, and a set of flexible tubing between them that carries a non-gaseous fluid. When the rollers apply pressure to the flexible tubing, the non-gaseous fluid is forced through the tubing.One advantage of this type of system is that the non-gaseous fluid in the tube does not come into contact with any of the engine components, making peristaltic pumps useful for pumping dirty, chemically hazardous, or contamination-sensitive fluids.

[0024] Because of these characteristics of peristaltic pumps, these types of systems are commonly used in a large number of industries, including medicine (such as dialysis or medical perfusion), agriculture, food manufacturing, chemical handling and manufacturing, engineering, aquariums, and wastewater treatment, as well as any other industry where maintaining separation between the mechanics of the pump and a non-gaseous fluid is advantageous.

[0025] Despite these advantages, one of the problems with peristaltic pump systems is that they generally require calibration, quality control, and quality assurance to establish and maintain a desired constant flow rate. This may involve using a non-gaseous calibration fluid through the peristaltic pump system to verify which motor speed corresponds to a particular non-gaseous fluid flow rate. However, with many non-gaseous calibration fluids, it can be difficult to clean the inside of the tubing, especially when a long coil of tubing is used. Non-gaseous fluids and liquids left inside the tubing can lead to microbial growth and contamination of samples during subsequent testing.Shorter sections of tube with connecting joints can be used to try to mitigate this problem by allowing a user to disassemble and clean the . While it is possible to dry the system, this often requires disassembling additional components from a larger system that houses the peristaltic pump. Drying procedures can also be implemented, but these can be time-consuming and result in extended downtime for a device that includes a peristaltic pump system. In a production environment, these drawbacks can be costly.

[0026] Consequently, there is a need for improved systems and methods that allow peristaltic pump systems to be tested cleanly, efficiently, accurately, and precisely for quality testing and / or calibrations in a cost-effective manner. The present disclosure addresses these needs and other long-unmet needs in the art.

[0027] In one aspect, this disclosure proposes a flow verification system for verifying the flow rate of a non-gaseous fluid through a peristaltic pump system, such as that contained in a Formula 300 delivery device (described in more detail herein with reference to Figures 3 to 7). However, it should be understood that the flow verification system of this disclosure can be used to verify flow rate in any peristaltic pump system, such as a system useful in the industries identified above.

[0028] If we look first at [Fig. 1], an embodiment of a flow verification system 100 is shown. [Fig. 1] is a schematic side view illustrating the flow verification system 100. The flow verification system 100 shown comprises a gas source 120, a plurality of flow channels 130, and a flow verification module 140. Additional structures, such as those illustrated in Figures 4 to 7, are not shown in [Fig. 1] to simplify the illustration of the overall schematic of the flow verification system 100.

[0029] In one embodiment, the gas source 120 comprises a gas source outlet 122 and a gas line 124. The gas source 120 may be a compressed gas cylinder, a gas compressor system, or any other suitable means of providing a pressurized gas source. In one embodiment, the gas source 120 further comprises a gas regulating mechanism, by means of which the gas flow from the gas source 120 may be modulated. The gas flows through the outlet of the gas source 122 and into the gas line 124. The gas line 124 is fluidically connected to a peristaltic pump inlet 102 of a peristaltic pump system 150. In one embodiment, the gas source 120 is configured to provide a constant flow of inlet air to the inlet of the peristaltic pump 102, thus allowing a constant flow of outlet air from the peristaltic pump system 150.When the outlet air from the 150 peristaltic pump system flows at a constant rate, the outlet air flows through the plurality. The flow rate of the outlet nozzles 115 is also constant. In one embodiment, the gas flow rate from the gas source 120 is configured to be at a level that allows peristalsis through each outlet nozzle of the plurality of outlet nozzles 115. By way of non-limiting examples, the gas flow rate can be regulated using a ball valve, a needle valve, a pressure regulator, and the like.

[0030] In one embodiment, the peristaltic pump system 150 comprises a peristaltic pump (such as the peristaltic pump 352 shown in [Fig. 4]), a motor (such as the motor 654 shown in [Fig. 6]), a gearbox (such as the gearbox 656 shown in [Fig. 6]), a peristaltic pump inlet 102, and a peristaltic pump outlet 106. In one embodiment, the peristaltic pump inlet 102 is a direct connection between the gas line 124 and the peristaltic pump system 150. In one embodiment, the gas line 124 connects directly to one or more formulation tubes passing through the peristaltic pump system 150. In one embodiment, the peristaltic pump inlet 102 comprises one or more formulation tubes (such as the first tube of formulation 302 and the second tube of formulation 303 shown in the [Fig.5]), a perforation part (such as the perforation part 354 shown in [Fig.5]), and a perforation tip (such as the perforation tip 355 shown in [Fig.5]), as discussed in more detail here with respect to Figures 4 and 5. The peristaltic pump outlet 106 is fluidically connected to a plurality of outlet nozzles 115.

[0031] In one embodiment, the plurality of flow channels 130 comprises a flexible tube. However, it should be understood that the plurality of flow channels 130 may be made of any suitable material structure, including, but not limited to, a plastic tube, a rubberized tube, a silicone tube, a metal tube, such as a steel tube, a glass tube, or the like. Each flow channel 130 of the plurality of flow channels 130 further comprises a flow channel inlet 132 and a flow channel outlet 134.

[0032] Each flow channel inlet 132 connects fluidically to each outlet nozzle 115 of the formula dispensing device 300. In one embodiment, the flow channel inlet 132 connects directly to each outlet nozzle 115. In another embodiment, each flow channel inlet 132 connects to each outlet nozzle 115 via an intermediate connection, such as a manifold or a valve. The flow channel outlets 134 are configured to connect fluidically to the flow control module 140. In one embodiment, each flow channel outlet 134 connects directly to the flow control module 140. In another embodiment, each outlet The flow channel 134 connects to each outlet nozzle 115 via an intermediate connection, such as a manifold or valve.

[0033] In the illustrated embodiment, the flow control module 140 is a plurality of water containers. In one embodiment, each water container in the plurality of water containers includes a water level. The water level in each water container is configured to prevent water from flowing back into the plurality of outlet nozzles 115. Without being constrained by theory, the water level varies with respect to the vertical position of the plurality of outlet nozzles 115 such that, at equilibrium, water does not flow back through the flow channels 130 and into the peristaltic pump system 150. This can be achieved by placing the water containers at a height lower than that of the plurality of outlet nozzles 115 and the peristaltic pump system 150.

[0034] Each water container in the plurality of water containers is configured to accept a flow of gas from each flow channel 130. When a gas flows through each outlet nozzle 115 of the formula delivery device 300 via the peristaltic pump system 150, a plurality of bubbles 148 are formed in each water container in the plurality of water containers. In some embodiments, the bubble formation rate is a qualitative indicator of the flow rate through the peristaltic pump system 150. In some embodiments, the bubble formation rate is a quantitative indicator of the flow rate through the peristaltic pump system 150. In some embodiments, the size of each bubble 148 and the quantity of bubbles 148 are indicative of the flow rate through the peristaltic pump system 150. In some embodiments, the plurality of water containers is two or more water containers.One advantage of using two or more water containers is that each outlet nozzle 115 of the plurality of outlet nozzles 115 can be matched to a water container, allowing individualized determination of the airflow through the peristaltic pump system 150 and through each outlet nozzle 115.

[0035] Although the plurality of water containers is represented and described with respect to water, it should be understood that the plurality of water containers can also be a plurality of liquid containers comprising any suitable liquid, such as an aqueous solution, a saturated aqueous solution, glycerin, a glycerin solution, a corn syrup solution, mineral oil, propylene glycol, ethylene glycol, or any other suitable liquid. In one embodiment, the liquid in the plurality of liquid containers has a viscosity, the viscosity being chosen to influence bubble formation, thereby providing additional information on the flow of a gas through the peristaltic pump system 150.

[0036] In one embodiment, such as that shown in [Fig. 2], the flow verification module 140 is the flow verification module 240. Additional structures, such as those illustrated in Figures 4 to 7, are not shown in [Fig. 2] to simplify the overall schematic of the flow verification system 100. In this respect, the flow verification module 240 comprises a plurality of flow sensors. Each flow sensor is configured such that, when air flows through each outlet nozzle 115 of the formula delivery device 300, a flow rate is recorded on each flow sensor. The flow sensors can be any suitable flow sensor, such as a flow velocity sensor, a flow meter, etc. In some embodiments, the flow rate is a non-zero flow rate.In some embodiments, each flow sensor is configured to indicate either the absence or the presence of non-zero flow through each flow sensor. In some embodiments, the non-zero flow is determined quantitatively. In one embodiment, the flow sensors can be any flow sensor suitable for measuring the flow rate of a gas, including, but not limited to, ultrasonic measuring devices, electromagnetic measuring devices, vane-wheel measuring devices, floating-element measuring devices, thermal measuring devices, pressure differential measuring devices, and the like.

[0037] When the non-zero flow rate is determined quantitatively, a flow rate divergence between each outlet nozzle 115 of the plurality of flow nozzles can be determined. Such a divergence can be used to identify internal flow defects in the formula delivery device 300 and the peristaltic pump system 150 it contains. In one embodiment, the non-zero flow rate of a gas through the flow sensors is compared to a gas density, a density of a predicted non-gaseous fluid formulation, and an air pressure correction factor to determine a formulation flow rate through the plurality of outlet nozzles 115. Such a determination is advantageous because it allows the characterization and calibration of the peristaltic pump system 150 without introducing non-gaseous fluids into the internal flow channels, thus avoiding the risk of contamination and microbial growth.Such a determination can also allow for faster quality control, which improves the efficiency of a manufacturing process for devices including a peristaltic pump system, such as the Formula 300 dispensing device.

[0038] In [Fig. 3], an embodiment of a formula dispensing device for applying a hair color formulation to a user is shown, as described in detail in US Patent No. 11,470,940. Maintaining a constant flow rate of formulation through the formula dispensing device 300 is important for a A high-quality user experience is essential. Therefore, it is advantageous to test each Formula 300 dispensing device before distribution to consumers. A flow verification system, such as the one described in relation to Figures 1 and 2, can be used to verify that the flow rate of a formulation is constant and uniform between each of the dispensing nozzles.

[0039] The formula delivery device 300 is shown in use with a plurality of outlet nozzles 330 to implement one or more methodologies or technologies such as, for example, applying a coloring formulation to a user's hair and / or scalp tissue. For example, some coloring formulations provide better results when applied to a targeted area of ​​the user's hair, for example, when treating the root segments of the hair, as described above. However, conventional hair coloring kits are generally configured for the manual mixing and application of the coloring formulation, a time-consuming process that is not well-suited for achieving consistent and desired results.Furthermore, the results obtained from conventional hair coloring kits often depend heavily on the technique, which requires training and familiarity with the process to achieve the desired results.

[0040] Using the embodiments of this disclosure, the coloring formulation can be applied to parts of the hair in a way that would be difficult to achieve with the direct application of the coloring formulation alone. Embodiments of this disclosure are also suitable for applying a treatment formulation to any surface of the user's body or any other suitable surface.

[0041] Although the formula delivery device 300 and other embodiments are described and illustrated as being used with a plurality of outlet nozzles 330, it should be understood that the formula delivery devices shown and described herein can be used with any suitable formulation applicator configuration and for any suitable use.

[0042] If we look again at [Fig. 3], the formula dispensing device 300 is represented as a device having a handle shell 310, a control button 306, a consumable assembly 320, and a separating surface 315. The handle shell 310 provides a surface that the user can grip with one hand while using the formula dispensing device 300. In this respect, the handle shell 310 has an ergonomic shape in the illustrated embodiments. However, in other embodiments, the handle shell 310 has, as appropriate, any shape to contain the internal components and provide one or more gripping surfaces for the user. In other embodiments In production, the consumable assembly 320 can form at least part of the gripping surfaces for the user.

[0043] The handle shell 310 houses various device control components, such as one or more of a drive motor having a gearbox, a central processing unit, a battery, a communication system (such as a wireless network (Wi-Fi), radio frequency identification (RFID), near field communication (NFC), BLUETOOTH®, etc.), an electrical and data connector at a port level (such as Universal Serial Bus (USB), FireWire, or similar), temperature sensors, accelerometers, fluid sensors, data scanners, light sources, a sound signal generator, fluid heating sources, temperature controllers, and other suitable control components, which are not shown in the figures for simplicity.In some embodiments, the port is used appropriately to provide an interface between the internal control components of the formula 300 dispensing device and external components / systems, and / or to charge the battery of the formula 300 dispensing device.

[0044] The control button 306 can be configured to activate, deactivate, and control elements of the formula dispensing device 300. By way of non-limiting example, the control button 306 can be a toggle switch, a push button, a capacitive switch, a potentiometer, or similar. In some embodiments, pressing the control button 306 energizes the formula dispensing device 300 such that the coloring formulation is drawn from a formulation container. In these embodiments, releasing the control button 306 can stop the flow of the coloring formulation.In some examples, the control button 306 can be used to initialize the formula dispensing device 300 or to place the formula dispensing device 300 into a state to perform certain functions, such as one or more of the following: calculating a mixing ratio of the coloring formulation components; entering a cleaning or purging mode; heating the formulation; collecting data from the formulation containers, such as remaining volume, mixing ratios, color information, etc.; sending and receiving signals through the port; analyzing data regarding user preferences; collecting data from sensors; providing status indications to the user, such as output power level, battery life, remaining formulation volume, sensor data, data connection information, etc.; and communication with auxiliary equipment. In some embodiments, the control button 306 is capable of pressure-sensitive operation. so that applying greater pressure to the control button 306 causes a variable response such as, for example, causing the formulation to flow more rapidly, the nozzles to move faster, or something similar. In some embodiments, various operating parameters can be controlled using a smart device, such as a phone, as described in detail in US patent application No. 14 / 586,138.

[0045] As illustrated in [Fig. 3], the consumable assembly 320 is removably assembled to the handle shell 310 to form the formula dispensing device 300. The external junction of the consumable assembly 320 and the handle shell 310 is located at the separation surfaces 315 on each assembly. The separation surfaces 315 are generally configured to mate together, forming a minimal gap to prevent fluids, dirt, debris, and other materials from entering the formula dispensing device 300. In some embodiments, the separation surfaces 315 mate together in a substantially flush configuration so that there are no sharp edges, thus ensuring ergonomic comfort for the user. Alternatively, in other embodiments, the handle shell 310 can be cut so that the consumable assembly 320 forms at least part of the gripping surfaces..

[0046] In the illustrated embodiments, to release and remove the consumable assembly 320 from the handle shell 310, a release button 316 (see [Fig. 4]) can be pressed to release the grip of a consumable assembly locking device from the release button 316. In other embodiments, other fastening configurations are appropriately used, such as a snap-fit, fasteners, hook and loop closure, removable adhesive, magnets, and the like. Additional fastening elements are also within the scope of this disclosure, such as a lower snap-fit, which can provide greater fastening force between the formula dispensing device 300 and the handle shell 310.In other embodiments, any number or combination of fastening elements is used appropriately to attach the consumable assembly 320 to the handle shell 310.

[0047] The consumable assembly 320 will now be described in more detail. The consumable assembly 320 generally includes a top cover 322 for housing and enclosing various components of the consumable assembly 320, which will be described in more detail below. The outlet area of ​​the top cover 322 includes a plurality of outlet nozzles 330 extending from a collector housing coupled to or formed on the top cover 322. The outlet nozzles 330 are configured to discharge the coloring formulation through a plurality of outlet openings in the tips of the outlet nozzles 330 when using the dispensing device. formula 300. In some embodiments, the outlet nozzle 330 is arranged in one or more rows along the length of the upper cover 322, generally in one direction along the length of the formula 300 delivery device, as shown in the figures. In other embodiments, the outlet nozzles 330 are appropriately placed at an angle to the length of the formula 300 delivery device.

[0048] In some embodiments, the outlet nozzles 330 have a length of between approximately 0.5 cm and approximately 4.0 cm from the manifold housing to the tips of the outlet nozzles 330 at the outlet openings. In other embodiments, the outlet nozzles 330 have a length of between approximately 1.4 cm and approximately 1.8 cm from the manifold housing to the tips of the outlet nozzles 330 at the outlet openings. In other embodiments, the outlet nozzles 330 have a length of approximately 1.6 cm from the manifold housing to the tips of the outlet nozzles 330 at the outlet openings. In other embodiments, any nozzle length is used appropriately.

[0049] In the illustrated embodiment, a plurality of spacer protrusions 340 extend outward substantially in the direction of the outlet nozzles 330 from the upper cover 322 in one or more rows. In this regard, substantially in the direction of the outlet nozzles 330 refers to an angle of approximately 25 degrees maximum from the direction along the length of the outlet nozzles 330. In the depicted embodiment, the first and second rows of spacer protrusions 340 are positioned along each side of a single row of outlet nozzles 330. In other embodiments, the spacer protrusions 340 may be arranged at an angle to the plurality of outlet nozzles 330. For example, see US Patent Application No. 15 / 339,551.

[0050] In some embodiments, each of the spacer protrusions 340 has a length (measured from the upper cover 322 to one end of the spacer protrusions 340) such that the end of the spacer protrusion 340 and the outlet openings of the outlet nozzles 330 are substantially coplanar. In other embodiments, the spacer protrusions 340 have a length (from the upper cover 322 to the end of the spacer protrusion 340) such that the spacer protrusions 340 are longer than a length of the outlet nozzles 330 (measured from the upper cover 322 to one end of the outlet nozzles 330).In this regard, during use, the 340 spacer protrusions will come into contact with an application surface, such as a localized area of ​​the scalp, and will space the outlet opening of the 330 outlet nozzles from the application surface to provide space for the discharge of the coloring formulation through the outlet opening. In embodiments where the spacing protrusions 340 are longer than the plurality of outlet nozzles 330, the spacing protrusions 340 are between approximately 0.1 mm and 5.0 mm longer than the length of each of the plurality of outlet nozzles 330. In other embodiments, the spacing protrusions 340 are between approximately 0.5 mm and 1.5 mm longer than the length of each of the plurality of outlet nozzles 330. In other embodiments, the spacing protrusions 340 are approximately 1.0 mm longer than the length of each of the plurality of outlet nozzles 330.

[0051] Turning now to the partial cross-sectional view of the formula delivery device 300 shown in [Fig. 4], the internal components of the formula delivery device 300 configured to dispense a coloring formulation through the outlet nozzles 330 will now be described (as described in detail in US Patent No. 11,470,940). As illustrated, a first formulation tube 302 and a second formulation tube 303 are configured to carry one component of a dye, developer, or other formulation from the fluid container to the collector housing for mixing and dispensing to the outlet nozzles 330. In other embodiments, a single formulation tube or more than two formulation tubes are appropriately used in the formula delivery device 300.The first formulation tube 302 and the second formulation tube 303 are conveyed to a peristaltic pump 352 consisting of a plurality of rollers to circulate the coloring formulation from the fluid container to the collector housing. In this respect, an advantage of a peristaltic pump is that the pump is self-priming.

[0052] The peristaltic pump 352 is driven by a suitable motor 654 (as shown in [Fig. 6]) located inside the handle housing 310. The motor can rotate the drive pinion via an extended drive shaft. The drive pinion interfaces with a driven pinion configured to drive the various components of the formula delivery device 300, including one or more peristaltic pumps 352, among other possible components. However, it should be understood that any suitable motor 654 can be used to drive the peristaltic pump 352.

[0053] If we now return to [Fig. 5], in some embodiments, the consumable assembly 320 is configured to be discarded after a specified period of use, for example after a single application of coloring formulation to the user's hair, as described in detail in US Patent No. 11,470,940. In these embodiments, the consumable assembly 320 is removed from the handle shell 310 for disposal, and a new consumable assembly 320 is installed in the handle shell 310 for further use.

[0054] For retail purposes, the packages of the consumable set 320 are initially sealed with a sealing element to prevent the dye and / or developer from leaking out of the package and to prevent contaminants from entering the packages. In some embodiments, the sealing element includes an orifice to establish fluid communication between the package and the first formulation tube 302 and / or the second formulation tube 303 when connected. In other embodiments, the sealing element may be perforated, so that the sealing element is perforated when connected to establish fluid communication between the package and the first formulation tube 302 and / or the second formulation tube 303 (as will be described in more detail below).In the punctureable embodiments, the sealing element is a unidirectional or bidirectional breathable membrane configured to allow degassing of the package without the entry of contaminants or the exit of the package contents. However, in other embodiments, the sealing element includes a valve, used in conjunction with any of the embodiments described herein, the valve being configured to regulate the flow of fluid from the packages. Any combination of the above features may also be used.

[0055] In the illustrated embodiment, when the consumable assembly 320 is inserted into the handle shell 310, the consumable assembly 320 changes from a sealed configuration, where the sealing element is intact, to a fluid flow configuration, where the sealing element has been opened to establish fluid communication between the package and the first formulation tube 302 and / or the second formulation tube 303. In embodiments where the sealing element can be pierced, the ends of the first formulation tube 302 and / or the second formulation tube 303 include a perforation portion 354 having a perforation tip 355 for piercing the sealing element when installing the consumable assembly 320 inside the handle shell 310.The perforation part 354 defines a fluid receiving chamber inside to receive the fluid and fluidically connect the package to the first formulation tube 302 and / or the second formulation tube 303.

[0056] Figures 6 and 7 depict a representative 600 peristaltic pump system, which is compatible with any of the formulation delivery devices, formulation cartridges, and cleaning cartridges described herein, as detailed in US Patent Application No. 18 / 060 258. The primary function of the 600 peristaltic pump system is to dispense a mixed formulation composed of two different formulations from a formulation cartridge onto the user's skin or hair. In some embodiments, the 600 peristaltic pump system dispenses the mixed formulation at a flow rate of 20 to 40 ml / min or 120 ml per four minutes, for example, 20 to 35 ml / min, 20 to 30 ml / min, 20 to 25 ml / min, 25 to 35 ml / min, 25 to 30 ml / min or 35 to 40 ml / min.

[0057] The peristaltic pump system 600 includes a first formulation inlet 603a and a second formulation inlet 603b, a first formulation tube 602 and a second formulation tube 603 fluidically connected to the first formulation inlet 603a and the second formulation inlet 603b, respectively. In some embodiments, the first formulation inlet 603a and the second formulation inlet 603b are each formed as rearward projections (i.e., toward the cartridge cavity when arranged in the reusable handle) from the first formulation tube 602 and the second formulation tube 603, respectively, toward a rear end of the reusable handle, the projections being configured to protrude into the formulation cartridge.

[0058] The formulation distribution assembly 600 also includes a motor 654, a gearbox 656 functionally connected to the motor 654, and a peristaltic pump 652 driven by the motor 654 via the gearbox 656. The use of a peristaltic pump has been shown to improve the distribution of the formulation when used in combination with the mixing chambers and conical formulation channels described herein.

[0059] The outlet nozzles 630 are fluidically connected to the first formulation tube 602 and the second formulation tube 603 via a turbulent mixing chamber, which mixes a first formulation from the formulation cartridge via the first formulation tube 602 with a second formulation from the formulation cartridge via the second formulation tube 603 to create a blended formulation. In particular, the turbulent mixing chamber mixes the two formulations by combining them in a common pressurized chamber and circulating the two formulations past one or more mixing elements, which create a turbulent flow of the blended formulation (as opposed to a laminar flow). The proportions of the first formulation relative to the second formulation vary in different embodiments.For example, in embodiments, the blended formulation is a mixture of a first formulation and a second formulation in a ratio of about 0.8:1.0 to 1.2:1.0, for example 0.85, 0.90, 0.95, 1.00, 1.05, 1.10 or 1.15.

[0060] In some embodiments, the plurality of outlet nozzles 630 have different nozzle outlet diameters. In some embodiments, a mixed formulation flow path fluidically connects the nozzle assembly to the mixing chamber, the mixed formulation flow path comprising at least one upstream mixed formulation reservoir which divides into a plurality of downstream mixed formulation reservoirs. In some embodiments, the pump The first non-gaseous fluid formulation and the second non-gaseous fluid formulation are drawn into the mixing chamber at a first flow rate and a second flow rate, respectively, the first flow rate being different from the second flow rate. In some embodiments, the first formulation tube 602 has a first diameter and the second formulation tube 603 has a second diameter, the first diameter being different from the second diameter. In some embodiments, the first diameter is smaller than the second diameter. In some embodiments, the first formulation source and the second formulation source are arranged in a formulation cartridge that can be reversibly coupled to the formulation dispensing assembly.

[0061] In operation, the peristaltic pump 652 draws the formulation from the connected formulation cartridge, through the first formulation tube 602 and the second formulation tube 603, through the turbulent mixing chamber, through the manifold, and through the outlet nozzles 630. In the illustrated embodiment, the first formulation tube 602 and the second formulation tube 603 are kept fluidly separate until downstream of the peristaltic pump 652 to prevent the two formulations from mixing until they reach the turbulent mixing chamber. Mixing the two formulations just before dispensing (i.e., between the peristaltic pump 652 and the manifold) improves the consistency of the blended formulation.

[0062] In one aspect, the present disclosure proposes a method for verifying flow in a peristaltic pump system. Looking at [Fig. 8], routine 800 illustrates a method for verifying flow according to one embodiment of the present disclosure. At block 802, a peristaltic pump system is connected to a gas source. At block 804, a peristaltic pump system is connected to a plurality of flow verification modules. The flow verification modules are fluidically coupled to the peristaltic pump system via a plurality of outlet nozzles fluidically connected to a plurality of flow channels comprising a plurality of flow path lengths.The plurality of flow path distances of the plurality of flow channels are different, and the gas flow facilitates a constant flow of gas out of the plurality of outlet nozzles which corresponds to a constant expulsion of a cosmetic composition from them with the use of the peristaltic pump system.

[0063] In block 806, pressurized gas flows from a gas source and is then introduced into a peristaltic pump inlet of the peristaltic pump system. In one embodiment, the pressurized gas source is configured to provide a constant flow of inlet air to the inlet of the peristaltic pump system, thus allowing a constant flow of outlet air from the plurality of nozzles. outlet of the peristaltic pump system. In one embodiment, the source of compressed gas is an air compressor.

[0064] At block 808, the peristaltic pump system is put into operation, which allows the pressurized gas flow to pass from an outlet of the compressed gas source through an internal flow channel usable with a peristaltic pump to a plurality of outlet nozzles of the peristaltic pump system.

[0065] At block 810, pressurized gas flows from the plurality of outlets of the peristaltic pump system into the plurality of flow control modules. The flow control modules are configured to provide a response to a gas flow within them.

[0066] In one embodiment, the plurality of flow-checking modules comprises a plurality of water containers, wherein the response includes the formation of bubbles in each water container of the plurality of water containers. Therefore, in optional block 812, the flow rate is checked by observing bubbles in the water containers.

[0067] In one embodiment, the plurality of flow verification modules comprises a plurality of flow sensors, wherein the response includes the recording of the gas flow rate by each flow sensor of the plurality of flow sensors. Therefore, in optional block 814, the flow rate is verified by recording a flow rate on the flow sensors.

[0068] In one embodiment, the plurality of flow verification modules comprises a plurality of flow sensors and a plurality of water containers, wherein, when a gas flows through each outlet nozzle of the plurality of outlet nozzles, bubbles form in each water container of the plurality of water containers, indicating at least one passage of gas through them to verify the flow in the peristaltic pump system, and wherein, when a gas flows through each outlet nozzle of the plurality of outlet nozzles, a flow is recorded on each flow sensor of the plurality of flow sensors, indicating at least one passage of gas through them to verify the flow in the peristaltic pump system.

[0069] In one embodiment, the flow rate is a gas flow rate value indicating a flow level. In one embodiment, the gas flow rate value is compared to a reference flow factor to verify a liquid flow rate value through the peristaltic pump system. By comparing this reference flow factor to the gas flow rate value, a liquid flow rate through the peristaltic pump system can be verified without any liquid actually flowing through the peristaltic pump system.
