[0017] The foregoing aspects and many advantages of the claimed subject matter will become more readily understood when taken in conjunction with the accompanying drawings and with reference to the following detailed description. Detailed Implementation

[0018] The description refers to one or more methods or techniques for allowing a user to apply a care preparation to human hair and scalp tissue. The following description provides representative examples that generally relate to hair and scalp care delivery systems, devices, and preparation cartridges thereof. In one embodiment, it is advantageous to apply the care preparation to a target portion of hair or scalp tissue. In one embodiment, it is desirable to apply the care preparation to a portion of hair near the scalp, for example, when a dye is applied to the root of the hair during a color-maintaining process. In another example, a method requires applying a scalp care preparation directly to the scalp tissue while minimizing contact with the hair.

[0019] Existing systems for the application of hair and scalp care preparations are widely used. In one example, hair dye kits are typically used to alter the appearance of hair color or to even out gray hair, among other uses. Existing hair dyeing systems have several drawbacks, including difficulty in use, time-consuming processes, uneven coverage, unpredictable results, and excessive messiness. In one aspect, existing hair dyeing systems may be ineffective in harmonizing and coloring the hair roots after new hair segments have grown from the scalp, where the natural hair color differs from the remaining portion of the dyed hair. This invention aims to address these and other needs.

[0020] In some embodiments, a hair dye formulation includes at least one dye and a separate developer, which are mixed in a controlled ratio. However, in this invention, "formulation" is not limited to dyes and developers. As used herein, the term "formulation" generally refers to any dye, developer, formulation, fluid, or any mixture thereof. In this invention, "formulation" includes: permanent hair dyes; semi-permanent hair dyes; developers; hair conditioners; and hair growth care products, such as those marketed under the trade name Rogaine. The products include minoxidil, hair protein care products, disulfide bond repair hair care products, fluid hair care products, and fluid scalp care products.

[0021] Embodiments of the present invention are configured to apply the formulation to target areas of hair and scalp tissue. While any of the above-described formulations may be suitably applied using the embodiments described herein, the present invention generally uses hair dye formulations as an example of a care formulation applied by the systems and apparatus described below. However, it should be understood that any system, apparatus, tube, and method may be used with any of the above-described formulations.

[0022] Figure 1 A representative formulation delivery system 100 according to the present invention is shown. The formulation delivery system 100 includes several different features, including a formulation product line 102, a formulation delivery device 104, and an optional application 106, which together enable a customized user experience.

[0023] The formulation product line 102 includes different formulations 108, each stored in the same (common) formulation cartridge type 110 configured for use with the formulation delivery device 104. The cartridges of the common formulation cartridge type are typically configured to be inserted into the cavity of a reusable handle of the formulation delivery device. For example, in some embodiments, the formulation cartridges and cleaning cartridges have a common cross-sectional shape and dimensions. Furthermore, some embodiments of the common formulation cartridge type have a common number and arrangement of output nozzles.

[0024] Therefore, the common formulation cartridge 110 type allows consumers to use many different formulations in a single formulation delivery device 104. (The following is a continuation of this discussion.) Figures 8A to 10 The text describes a representative formulation cartridge type 110, and... Figure 12 The text describes a representative cleaning cylinder 112.

[0025] In a representative embodiment, formulation product line 102 includes hair coloring formulations and scalp care formulations. In other representative embodiments, formulation product line 102 includes at least two, three, four, five, six, seven, or eight different formulations, each stored within the same formulation cartridge type 110: permanent hair coloring and developer; semi-permanent hair coloring and developer; shampoo; conditioner; hair growth care products such as minoxidil; hair protein care products; disulfide bond repair hair care products; or fluid scalp care products. In a further representative embodiment, formulation product line 102 includes any of the above combinations in addition to an optional cleansing cartridge 112 of the same formulation cartridge type 110.

[0026] The formulation cartridge 110 type has an elongated shape and size, configured for insertion into the handle of the formulation delivery device 104, particularly into the cartridge cavity of the handle. In some embodiments of the formulation delivery system 100, the elongated housing has different constructions between the formulation cartridge 110 containing the formulation and the cleaning cartridge 112, but has a common shape and size. For example, in some embodiments, the formulation cartridge 110 containing the formulation has... Figures 8A to 10 The partial recyclable embodiment shown has a construction, while the cleaning cylinder 112 has a similar shape and size, but different materials and components.

[0027] Another feature of the formulation cartridge 110 type is a plurality of liquid outlet nozzles, which are sized and positioned at the distal (front) end of the formulation cartridge 110 in a configuration fluidly connected to a corresponding plurality of liquid inlets (e.g., a first formulation inlet). In some embodiments, the liquid outlet nozzles are valves for formulation packets disposed within the formulation cartridge 110.

[0028] A representative type of formulation cartridge 110 is configured for insertion into a formulation delivery device 104 and for storing a first formulation and a second formulation, such as... Figures 8A to 10 As shown.

[0029] The cleaning cartridge 112 is of the common type of formulation cartridge 110 (i.e., having common external dimensions and multiple liquid outlet nozzles), which allows the user to clean the formulation delivery device 104 by performing a cleaning procedure that flushes a cleaning solution (e.g., water) from the cleaning cartridge 112 through the fluid conduits of the formulation delivery device 104, thereby removing residual formulation from the formulation delivery device 104. Advantageously, the cleaning cartridge 112 and the cleaning procedure enable a large portion of the formulation delivery device 104 to be reused for different formulations, thereby reducing waste and cost.

[0030] The cleaning cartridge 112 includes a refillable cleaning fluid reservoir disposed inside the housing and fluidly connected to a plurality of output nozzles. Thus, a user can fill the cleaning fluid reservoir with cleaning fluid (e.g., water), perform multiple cleaning procedures on the formulation delivery device 104, and refill the cleaning fluid reservoir.

[0031] The formulation delivery device 104 is a connected electromechanical device that interacts with the user, the formulation cartridge 110, and optionally with the application 106 to provide a customized and personalized user experience. See below for further details. Figures 4 to 7 To describe representative formulation delivery devices and their subsystems.

[0032] Typically, the formulation delivery device 104 includes a reusable handle configured to receive a formulation cartridge 110, and a formulation dispensing assembly and a controller, both housed within the reusable handle. The formulation dispensing assembly includes at least one fluid conduit fluidly connected to a motorized pump and a reciprocating nozzle assembly, and is configured to draw formulation or cleaning solution from the formulation cartridge 110 and dispense the formulation or cleaning solution onto the user's hair, scalp, or body via the reciprocating nozzle assembly.

[0033] The controller is configured to switch between at least a cleaning procedure and a preparation procedure in response to one or more inputs instructing the insertion of a cleaning cartridge or preparation cartridge into the reusable handle. The controller communicates with an encrypted chip reader at the cartridge authentication interface in the reusable handle to read the encrypted chip located on the preparation cartridge 110 to authenticate which preparation 108 is stored in the preparation cartridge 110 inserted into the reusable handle at any given time. In some embodiments, the controller also performs authentication when the cleaning cartridge 112 is inserted into the reusable handle. Based on the authenticated preparation 108 or cleaning cartridge 112, the controller causes the preparation delivery device 104 to perform a preparation procedure that dispenses the authenticated preparation from the preparation cartridge via a preparation dispensing assembly. Based on the authenticated cleaning cartridge 112, the controller also causes the preparation delivery device 104 to perform a cleaning procedure that dispenses cleaning fluid via a preparation dispensing assembly.

[0034] Application 106 includes logic configured to run on a non-transitory machine-readable storage medium and includes modules for personalizing the user experience, providing useful analytics, and enabling e-commerce. Application 106 runs on mobile device 114 such as a smartphone, tablet, etc., and interacts with a user (e.g., an end user or salon technician) to provide executable information through multiple modules, which will be referenced below. Figure 3 The following description is provided. In some embodiments, application 106 communicates with formulation delivery device 104 and network 116, which, exemplarily, is a mobile network, a cloud-based enterprise network, a local area network, etc.

[0035] The formulation product line 102, the formulation delivery device 104, and the application 106 together provide an improved, customized user experience. Each of the aforementioned components of the formulation delivery system 100 will now be described in detail.

[0036] Figure 2 A schematic overview diagram of a representative formulation delivery device 200 is shown to facilitate understanding of some of its representative features. The formulation delivery device 200 should be understood to have features similar to... Figure 1 The same features as the formulation delivery device 104

[0037] The formulation delivery device 200 includes a reusable handle 202 having a hollow, elongated portion configured to reversibly receive a common formulation cartridge type (including a cleaning cartridge 112). The reusable handle 202 also houses multiple sub-components, including a controller 204 comprising a processor 206 and a data storage 208 storing multiple modules (described below), a cartridge authentication interface 210, a power supply 212, a formulation dispensing assembly 214, and an optional position sensor 216.

[0038] In some embodiments, power supply 212 is a direct current (DC) power source, such as a rechargeable battery (e.g., a lithium-ion battery) configured to be charged by being plugged into a household AC outlet. In other embodiments, power supply 212 is an alternating current (AC) power source, such as ordinary household AC power supplied to the formulation delivery device 200 via a power cord (not shown).

[0039] The formulation dispensing assembly 214 provides formulations and / or cleaning solutions from the formulation cartridge 110 to the user's scalp or hair. In one embodiment, the formulation dispensing assembly 214 includes: a first fluid conduit fluidly connected to a first formulation inlet (which is connected to a first liquid output nozzle of the formulation cartridge 110), a second fluid conduit fluidly connected to a second formulation inlet (which is connected to a second liquid output nozzle of the formulation cartridge 110), a motor 218, a pump 220 driven by the motor 218, and a reciprocating nozzle assembly 222 also driven by the motor 218.

[0040] The cartridge authentication interface 210 is a radio frequency identification (RFID) reader, near field reader, etc., located in the reusable handle 202, so that when the preparation cartridge 110 is inserted therein, the cartridge authentication interface 210 reads the encryption chip set on the preparation cartridge 224, so as to authenticate the preparation cartridge in conjunction with the preparation program module 226 described below.

[0041] Optional position sensor 216 includes one or more sensors, individually or collectively, that assist in determining the position and orientation of the formulation delivery device 200 relative to the user's scalp or hair. In some embodiments, position sensor 216 includes one or more accelerometers, touch sensors (e.g., capacitive touch sensors), proximity sensors (e.g., optical proximity sensors), etc. Controller 204 and certain modules thereof use signals transmitted from position sensor 216 to improve the accuracy and efficiency of applying the formulation to the user's hair or scalp.

[0042] Controller 204 is operatively connected (e.g., electrically connected) to power supply 212, cartridge authentication interface 210, dosage dispensing assembly 214, and optional position sensor 216. Controller 204 includes processor 206 (e.g., general-purpose processing unit, graphics processing unit, or application-specific integrated circuit), data memory 926 (tangible machine-readable storage medium), and multiple modules implemented as software logic (e.g., executable software code), firmware logic, hardware logic, or various combinations thereof. In some embodiments, controller 204 includes a transceiver that transmits signals from any of the modules discussed below to the mobile device and receives signals transmitted from the mobile device.

[0043] In some embodiments, the controller 204 includes a communication interface having circuitry configured to communicate with a formulation delivery system including a formulation cartridge 224 (encryption chip), a cleaning cartridge 228, a cartridge authentication interface 210, a mobile device and an application stored thereon, and / or other network elements via the Internet, cellular networks, radio frequency (RF) networks, personal area networks (PANs), local area networks, wide area networks, or other networks. Therefore, the communication interface can be configured to use wireless protocols (e.g., The communication interface can communicate via cellular, infrared, near-field, and / or wired protocols (Universal Serial Bus or other serial communication buses such as RS-216, RJ-45, etc., parallel communication buses, etc.). In some embodiments, the communication interface includes circuitry configured to initiate a discovery protocol, which allows the controller 204 and other network elements (e.g., formulation cartridge 110) to recognize each other and exchange control information (e.g., an identifier of the formulation stored in the formulation cartridge 110). In one embodiment, the communication interface has circuitry configured to discover the protocol and negotiate one or more pre-shared keys.

[0044] Data storage 208 is a tangible machine-readable storage medium, including mechanisms for storing information in a non-transitory form accessible to a machine (e.g., processor 206 or mobile device 114). For example, machine-readable storage media include recordable / non-recordable media (e.g., read-only memory (ROM), random access memory (RAM), disk storage media, optical storage media, flash memory devices, etc.).

[0045] The modules described below are representative and not limiting. Therefore, some embodiments of controller 204 include additional modules, while other embodiments include fewer than all of them.

[0046] The cartridge authentication module 230 communicates with the cartridge authentication interface 210 to authenticate any dosage cartridge 224 or cleaning cartridge 228 inserted into the reusable handle 202. For example, when a dosage cartridge 224 is inserted into the reusable handle 202, the cartridge authentication interface 210 reads encrypted information from an encryption chip disposed on the dosage cartridge 224. If the cartridge authentication interface 210 successfully reads the encrypted information from the encryption chip, the cartridge authentication module 230 "unlocks" the dosage delivery device 200, such as the dosage program module 226. However, if the cartridge authentication interface 210 cannot successfully authenticate the dosage cartridge inserted into the reusable handle 202, it does not unlock the dosage delivery device 200. For example, if the dosage cartridge is a counterfeit cartridge or another cartridge containing inferior dosage, the cartridge authentication module 230 does not unlock the functionality of the dosage delivery device 200. In this way, the cartridge authentication module 230 advantageously prevents user harm or a poor experience.

[0047] In some embodiments, the tube authentication module 230 is configured to read additional information from the encryption chip, including one or more of the following: formulation identifier, starting dosage, formulation expiration date, or formulation manufacturing date. In such embodiments, the tube authentication module 230 transmits the additional information to other modules for subsequent use.

[0048] The formulation program module 226 stores multiple formulation programs (e.g., hair care formulation programs) for different formulations and enables the formulation dispensing assembly 214 to execute one or more formulation programs based on a formulation cartridge 224 certified by the cartridge certification module 230. The formulation program dispenses certified formulation 108 from the formulation cartridge 224 via the reciprocating nozzle assembly 222. For example, for a specific dispensing time, the hair care formulation program dispenses one or more hair care formulations from the reciprocating nozzle assembly 222 at a specific pump flow rate, the nozzle reciprocating frequency and / or reciprocating amplitude of the reciprocating nozzle assembly 222, and / or other device operating parameters specified by the formulation program stored in the formulation program module 226. In this way, the formulation delivery device 200 adjusts one or more device operating parameters based on a specific formulation stored in the certified formulation cartridge 224 inserted within the formulation delivery device for more effective hair and scalp care.

[0049] In some embodiments, the formulation procedure module 226 determines the volume of certified formulation dispensed from the formulation cartridge via the formulation dispensing component based on the dispensing time of the certified formulation. Based on the dispensing time and / or dispensing volume, the formulation procedure module 226 causes a visual indicator on the reusable handle 202 to signal the remaining dosage. This helps the user predict when the formulation cartridge needs to be replaced and prompts the user to conveniently obtain additional formulation cartridges using the e-commerce module of the connected application.

[0050] The cleaning program module 232 stores cleaning programs and, after the cleaning cartridge 228 (which has a reservoir filled with cleaning fluid) is inserted into the reusable handle 202 and certified by the cartridge certification module 230, causes the formulation dispensing assembly 214 to perform the cleaning program. The cleaning program dispenses cleaning fluid from the certified cleaning cartridge 228 via the reciprocating nozzle assembly 222 (e.g., at a predetermined time and flow rate) to remove any residual formulation from the formulation dispensing assembly 214. The cleaning program is useful, for example, after the use of one formulation in the formulation delivery device 200 but before the use of a second, different formulation. In some embodiments, the cleaning program operates the pump 220 at a higher flow rate than one or more (or all) of the formulation programs stored in the formulation program module 226 to remove all residual formulation.

[0051] In some embodiments, controller 204 is configured to switch between at least a cleaning procedure (provided by cleaning procedure module 232) and a formulation procedure (provided by formulation procedure module 226) in response to one or more inputs instructing the insertion of a cleaning cartridge or formulation cartridge into a reusable handle. Representative inputs include certification of the formulation cartridge or cleaning cartridge provided by cartridge certification module 230.

[0052] According to the method of the present invention, a method for cleaning any formulation delivery device includes inserting a cleaning cartridge, at least partially filled with cleaning fluid, into a reusable handle of the formulation delivery device and performing a cleaning procedure until the cleaning fluid dispensed by the formulation dispensing assembly becomes clear.

[0053] The power management module 234 supplies power from the power source 212 to one or more of the controller 204, the cartridge authentication interface 210, the formulation dispensing assembly 214, or the position sensor 216. Furthermore, the power management module 234 conserves available power resources (e.g., saves battery life) by switching the formulation delivery device 104 between a sleep state (passive state) and a wake-up state (active state).

[0054] The sleep / wake module 236 manages whether the formulation delivery device 200 is in a wake-up state or a sleep state. The formulation delivery device 200 is in a sleep state by default, thus receiving little or no power from the power supply 212 to the formulation dispensing assembly 214, the cartridge authentication interface 210, and / or the controller 204. In the sleep state, the formulation delivery device 200 cannot perform formulation or cleaning procedures. In contrast, in the wake-up state, the controller 204, the cartridge authentication interface 210, the formulation dispensing assembly 214, and the position sensor 216 are fully powered, enabling the formulation delivery device 104 to perform one or more formulation or cleaning procedures. In some embodiments, the formulation delivery device 104 is "wake up," i.e., transition from a sleep state to a wake-up state, by pressing a button on the reusable handle 202 or by inserting the formulation cartridge 224 or cleaning cartridge 228 into the reusable handle 202. In some embodiments, the formulation delivery device 200 returns to a sleep state after a predetermined inactivity period (e.g., a 120-second inactivity period).

[0055] The position module 238 uses the position signal provided by the position sensor 216 to determine the position of the formulation delivery device 200, and then provides the position information to the formulation program module 226 to execute a formulation program (e.g., a calibration program). In some embodiments, the position module 238 provides the position signal (via a transceiver) to an application stored on a mobile device, exemplarily, to enable the execution of a calibration program (described below) and / or to enable the application to display the correct application instructions based on the position signal.

[0056] Figure 3 A schematic overview diagram of a representative application 300 is shown, which should be understood to have Figure 1 Application 300 possesses all the features of application 106 and is compatible with all formulation delivery systems and devices of the present invention. As described above, application 300 is configured to run on a device, such as a mobile device like a smartphone or tablet. As a representative example, application 300 is described in the context of mobile device 302 connected to network 304; however, this is not limiting.

[0057] The mobile device 302 includes a display 306 (e.g., an LED or LCD display), a processor 308, and a data storage 310 storing multiple modules. The terms “processor,” “data storage,” and “module” have the same meanings as described above with respect to the controller 204, and are used below in conjunction with the representative formulation delivery device.

[0058] Each module described below presents one or more user interfaces on display 306. Display 306 is a touch-sensitive display configured to receive user input. Therefore, for each module, the user interface presented on display 306 is configured to both display information and receive user input.

[0059] Application 300 includes multiple modules for personalizing the user experience, including a user profile module 312 and a user program module 314. The modules described below are representative and not limiting. Therefore, some embodiments of application 300 include additional modules, while other embodiments include fewer than all modules.

[0060] User profile module 312 creates one or more profiles for the user of the formulation delivery device 104. These profiles are provided as input to other modules, such as user program module 314 and e-commerce module 316. Therefore, user profile module 312 provides one or more user interfaces that prompt the user to provide one or more user profile inputs, including: hair color, hair type (e.g., curly, straight), colored / non-colored state, ethnicity, hair condition (e.g., damaged), scalp condition (e.g., itchy), and / or age. User profile module 312 accepts and stores user profile inputs.

[0061] In some embodiments, the user profile module 312 communicates with the user program module 314 by providing one or more or the entire user profile from the user profile input to the user program module 314. The user program module 314 then uses one or more of the user profile inputs to create one or more user-specific programs for the user and / or select one or more tutorials to be displayed on the display 306.

[0062] In some embodiments, the user profile module 312 communicates with the formulation delivery device 104. For example, in some embodiments, the user profile module 312 adjusts at least one device operating parameter (e.g., flow rate, dispensing time, reciprocating amplitude, or reciprocating frequency) of the formulation program generated by the formulation program module based on one or more of the user profile inputs.

[0063] In some embodiments, the user program module 314 helps users effectively utilize the connected formulation delivery device by developing one or more user-specific programs for each user based on one or more user profile inputs. That is, the user program module 314 establishes new formulation programs (rather than selecting predetermined formulation programs) to effectively handle one or more conditions identified by the user profile inputs, or to achieve one or more goals identified by the user profile inputs. As a representative example, if the user input indicates that the user's hair is dyed and damaged, the user program module 314 establishes a user-specific program that selects a hair repair formulation and shampoo formulation suitable for the user's hair color from the formulation product line, and displays a user-specific procedure (e.g., as instructions) for using the selected hair repair formulation and shampoo at defined intervals to improve the health of the user's hair.

[0064] In addition, the user program module 314 is displayed on the display 306 as: a) one or more passive tutorials for formulation procedures, cleaning procedures and / or calibration procedures; and / or one or more active instruction sets that instruct the user when the user uses the formulation delivery device.

[0065] In some embodiments, the user program module 314 receives one or more or all user profiles from user profile inputs in the user profile module 312, and then displays a passive tutorial (e.g., a pre-recorded instructional video) for the user based on the received user profile inputs or the user profile. As an example, the user program module 314 receives user profile input from the user profile module 312 indicating that the user has dyed hair, and displays a tutorial on the display 306 showing the user how to use the formulation delivery device to color the user's hair.

[0066] In some embodiments, the user program module 314 receives one or more position signals from a position sensor of the formulation delivery device via a controller. Based on the received position signals, the user program module 314 instructs the user on how to use the formulation delivery device when the user is using it (e.g., instructions to move the formulation delivery device to a specific spatial boundary in a specific direction, at a specific speed, or in a specific pattern). As an example, the user program module 314 receives a position signal from a position sensor indicating that the formulation delivery device is positioned at the user's left temple; based on this received position signal, while dispensing the scalp care formulation, the user program module 314 displays a video instructing the user to apply the scalp care formulation by moving the formulation delivery device from the left temple to the right temple.

[0067] In some embodiments, the user program module 314 receives a position signal from the formulation delivery device and displays the correct application instructions based on the position signal.

[0068] The calibration module 318 assists the user in calibrating the formulation delivery device, which in turn increases the effectiveness of the formulation procedures performed by the device. In some embodiments, the calibration module 318 displays a passive tutorial (e.g., a pre-recorded instructional video) instructing the user on how to complete the calibration procedure. In some embodiments, the calibration module 318 provides one or more active sets of instructions that instruct the user on how to use the complete calibration procedure when using the formulation delivery device and when the calibration module 318 receives a position signal from the device.

[0069] According to a representative calibration procedure, calibration module 318 instructs the user to position the dosage delivery device at multiple calibration locations on the user's body, for example, in a specific order (e.g., left temple, then right temple, then front hairline, then back hairline). The user then moves the dosage delivery device to each calibration location, indicated by pressing a button or other action on the dosage delivery device when the device is in a designated calibration location, and / or when the user moves the dosage delivery device from one calibration location to another.

[0070] Based on position signals received from position sensors of the formulation delivery device, calibration module 318 and / or the formulation delivery device record a calibration position. Then, calibration module 318 and / or the formulation delivery device adjust one or more user-specific programs based on the recorded calibration position. In some embodiments, this adjustment step includes adjusting the spatial constraints and / or temporal duration of one or more formulation programs stored in a formulation program module.

[0071] The manual adjustment module 320 enables users to manually adjust one or more device operating parameters of the formulation delivery device (e.g., flow rate, dispensing time, reciprocating amplitude, or reciprocating frequency) to facilitate greater control over the formulation delivery device and a more customized user experience. Therefore, the manual adjustment module 320 presents a user interface with one or more user-adjustable virtual sliders, switches, editable value ranges, etc., configured to receive one or more operating parameter inputs from the user. The manual adjustment module 320 receives the operating parameter inputs and transmits them to the formulation delivery device (e.g., the formulation program module), which adjusts the corresponding device operating parameters based on the relevant operating parameter inputs (e.g., matching the operating parameter inputs).

[0072] Analysis module 322 receives device operating parameters (e.g., device operating parameters from the formulation delivery device) and calculates useful analyses, which are then provided to a user via a user interface and / or to a third party via network 304. Representative analyses include: formulation usage patterns, formulation purchase predictions, and diagnostics of the formulation delivery device. In some embodiments, analysis module 322 communicates with network 304 (e.g., an analysis platform hosted on one or more cloud-based servers) to retrieve additional information and / or calculate the analyses.

[0073] In some embodiments, the formulation delivery device includes a position sensor that sends a position signal to a controller, and a transceiver that sends a position signal to a mobile device. The formulation delivery device transmits the position signal to an analysis module 322, which retrieves user suggestions from an analysis platform on network 116 based on the received position signal and displays the user suggestions.

[0074] The formulation creation module 324 enables a user to create a custom formulation based on the user's selection of one or more formulation inputs, corresponding to one or more desired results (e.g., desired hair color), one or more formulation inputs (e.g., indication of user hair damage), and / or one or more user profile inputs provided to the user profile module 312. Therefore, the formulation creation module 324 is configured to receive one or more user profile inputs from the user profile module 312 and formulate a custom formulation based on these inputs.

[0075] To facilitate the creation of custom formulations, the formulation creation module 324 provides the user interface with one or more user-adjustable virtual sliders, switches, editable value ranges, etc., corresponding to each formulation input. In some embodiments, the formulation creation module 324 communicates with a network 304 (e.g., a database of formulations hosted on one or more cloud-based servers) to retrieve additional information and / or formulate the custom formulation.

[0076] The e-commerce module 316 presents a purchase interface that enables users to purchase (including on a one-time purchase or pre-order) products related to the formulation delivery device. In some embodiments, the e-commerce module 316 retrieves one or more custom formulations from the formulation creation module 324 (or its components) and presents the user with the option to purchase one or more formulation cartridges 110 containing the custom formulation on the purchase interface. In some embodiments, the e-commerce module 316 retrieves one or more user profile inputs and / or user-specific program inputs from the user profile module 312 and presents the user with the option to purchase one or more formulation cartridges targeting the user profile input (e.g., a formulation cartridge containing a hair repair formulation in the case of user input indicating hair damage). In some embodiments, the e-commerce module 316 presents the option to purchase a cleaning cartridge 112 or the formulation delivery device 104 and / or its components on the purchase interface. Such a purchase interface and purchase options may be based on formulation purchase predictions and / or formulation usage patterns retrieved by the analysis module 322.

[0077] Figures 4 to 5 A representative formulation delivery device 400 and its components according to an embodiment of the present invention are shown. The formulation delivery device 400 is configured to receive formulation cartridges of type 402 (including cleaning cartridges of the same type). Examples of formulation cartridges of type 402 are described below. Figures 8A to 10 Described in detail; Figure 4 The formulation cartridge 402 shown should be understood to have the same features as described therein. Some embodiments of the formulation delivery device 400 include the formulation cartridge 402 and / or an optional through-adapter 404.

[0078] The formulation delivery device 400 includes a reusable handle 406 formed of ABS plastic or a similar rigid polymer or other material. In some embodiments, the handle 406 is an assembly of multiple housings configured to be connected together by fastening elements such as snap-fits, bolts, etc. The reusable handle 406 has a hollow, elongated clamping portion with a cylindrical cavity sized and sized to receive a formulation cartridge 402. In some embodiments, the cavity includes keying features that facilitate proper insertion of a formulation cartridge 402. For example, some embodiments include a cartridge interface 408 disposed in an opening and having a flat mating surface that engages with a corresponding mating surface of the formulation cartridge 402 when the cartridge 402 is properly inserted into the opening.

[0079] In addition to the controller 412, the reusable handle 406 also houses the formulation dispensing assembly 410 (see below). Figures 5 to 7(Description to follow). The formulation dispensing assembly 410 and the controller 412 each have... Figure 2 The formulation dispensing component 214 and the controller 204 have the same characteristics. See below for reference. Figures 6 to 7 Detailed description of embodiments of the formulation dispensing components; Figure 4 The formulation dispensing component 410 shown should be understood to have the same characteristics as described therein.

[0080] The formulation dispensing assembly 410 dispenses formulation or cleaning solution from the formulation cartridge 402 and includes a pump, a fluid conduit, a mixing chamber, and a reciprocating nozzle assembly 414 (described below) with nozzles extending remotely from the front end of a reusable handle 406 between a plurality of optional support portions 416. The reciprocating nozzle assembly 414 includes a plurality of annular nozzles that reciprocate along a track of the reusable handle 406 while dispensing the formulation onto the user's skin or hair. In some embodiments, the reciprocating nozzle assembly 414 reciprocates with a reciprocating amplitude of 7.0–12.0 mm (e.g., 8.0 mm–11.0 mm, or 9.0–10.0 mm) and / or a reciprocating frequency of 5.0 Hz–10.0 Hz (e.g., 6.0 Hz–9.0 Hz, 6.0 Hz–8.0 Hz), which can be adjusted by a formulation program module, a cleaning program module, a user program module, a manual adjustment module, or other modules.

[0081] like Figure 5 As shown, the formulation cartridge 402 has one or more formulation packets 418 disposed therein, each having an output nozzle 420 that protrudes through the distal (front) end of the formulation cartridge 402 in a configuration that is fluidly connected to a corresponding formulation inlet 422 of the formulation dispensing assembly 410 when the formulation cartridge 402 is fully inserted into the cartridge cavity 424.

[0082] A button 426, located on a reusable handle 406 and electrically connected to a controller 412, activates the features of the aforementioned formulation delivery device 400. In some embodiments, pressing the button 426 activates the features of the aforementioned formulation delivery device 400. Figure 2 Features of any module described herein. For example, in some embodiments, pressing button 426 activates a sleep / wake-up module stored in controller 412, thereby waking the formulation delivery device 400 from a sleep state to a wake-up state. In some embodiments, pressing button 426 activates a formulation program module stored in controller 412 when the formulation cartridge is inserted into the reusable handle 406, thereby initiating the formulation program.

[0083] In some embodiments, when the cleaning cartridge is inserted into the reusable handle 406, pressing button 426 activates the cleaning program module stored in controller 412, thereby initiating the cleaning program. A visual indicator 428 (e.g., an LED) positioned along the reusable handle 406 indicates one or more of the remaining dosage or remaining battery life, for example, based on a dispensing time determined by the controller's formulation program module. Some embodiments include additional buttons and / or different numbers of visual indicators 428 with different functions, and the embodiments shown are not limiting. In some embodiments, the visual indicator 428 is a multi-segment LED, each segment corresponding to an equal proportion of the formulation remaining in the dosage cartridge.

[0084] The controller 412 includes logic (stored in its data memory) that, when executed by the controller 412's processor, causes a cartridge authentication interface 430 (e.g., an RFID reader) located in the reusable handle 406 to read an encryption chip 432 on the dosage cartridge 402 to authenticate the dosage cartridge 402. The encryption chip 432 stores at least one of the following: dosage cartridge 402, dosage identification, starting dosage, dosage expiration date, or dosage manufacturing date.

[0085] The controller 412 also includes logic that, when executed, causes the formulation delivery device to perform a formulation procedure based on the authentication of the formulation cartridge 402, which dispenses a mixed formulation (of the first and second formulations) from the formulation cartridge 402 via the formulation dispensing assembly. For example, the formulation delivery device authenticates the first and second formulations after (or while inserting the formulation cartridge into the reusable handle) the formulation cartridge, and then, in response to pressing a button on the reusable handle, executes a formulation procedure that causes the formulation dispensing assembly 410 to continuously or frequently mix the first and second formulations, and dispenses the same formulation from the reciprocating nozzle assembly at one or more of the following predetermined device operating parameters whenever the button is pressed: formulation flow rate, reciprocating frequency, or reciprocating amplitude.

[0086] In some embodiments, the controller 412 further includes logic, when executed, that causes the formulation delivery device to perform a cleaning procedure based on an authenticated cleaning cartridge inserted into a reusable handle, the cleaning procedure dispensing cleaning fluid via a formulation dispensing assembly. For example, the formulation delivery device authenticates the cleaning cartridge inserted into the reusable handle and then, in response to pressing a button on the reusable handle, performs a cleaning procedure that causes the formulation dispensing assembly 410 to continuously or frequently dispense cleaning fluid (e.g., water) from a reciprocating nozzle assembly at one or more of the following predetermined device operating parameters when the button is pressed: cleaning fluid flow rate, reciprocating frequency, or reciprocating amplitude. In some embodiments, the cleaning fluid flow rate is higher than any formulation flow rate stored in one or more formulation programs in the controller 412 to facilitate efficient rinsing of residual formulation from the formulation dispensing assembly.

[0087] A through-adapter 404 is attached to a reusable handle 406 on a reciprocating nozzle assembly 414. In some embodiments, the through-adapter 404 provides an auditory feedback signal when properly engaged with the reusable handle 406.

[0088] Figures 6 to 7 A representative formulation dispensing assembly 600 is shown, which is compatible with any formulation delivery device, formulation cartridge, and cleaning cartridge described herein. The primary function of the formulation dispensing assembly 600 is to dispense a mixture of two different formulations from the formulation cartridge onto the user's skin or hair. In some embodiments, the formulation dispensing assembly 600 dispenses the mixture at a flow rate of 20 to 40 mL / min or 120 mL every four minutes, for example, at a flow rate of 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.

[0089] The formulation dispensing assembly 600 includes a first formulation inlet 602 and a second formulation inlet 604, a first fluid conduit 606 and a second fluid conduit 608, which are fluidly connected to the first formulation inlet 602 and the second formulation inlet 604, respectively. In some embodiments, each of the first formulation inlet 602 and the second formulation inlet 604 is formed as a protrusion extending rearward from the first fluid conduit and the second fluid conduit toward the rear end of a reusable handle (i.e., toward the cylinder cavity when disposed in the reusable handle), the protrusion being configured to project into the formulation cylinder.

[0090] The formulation dispensing assembly 600 also includes a motor 610, a gearbox 612 operatively connected to the motor 610, and a pump 614 driven by the motor 610 via the gearbox 614. In some embodiments, the pump 614 is a peristaltic pump, which has been found to improve formulation dispensing when used in conjunction with the mixing chamber and tapered formulation channel described herein.

[0091] The reciprocating nozzle assembly 616 includes a plurality of annular nozzles 618 disposed on a comb 620, which, in use, circulate back and forth along a track of a reusable handle 406 while dispensing formulation onto the user's skin or hair for more uniform formulation coverage. Each of the nozzles 618 includes a formulation channel 622 passing through it, each formulation channel 622 being fluidly connected via a manifold 624 to a first fluid conduit 606 and a second fluid conduit 608. In some embodiments, each formulation channel 622 is tapered to facilitate increased formulation dispensing speed and / or to further mix the two formulations. Tapered formulation channels have proven advantageous when used in conjunction with other features described herein, such as where the pump 614 is a peristaltic pump, and / or where the turbulent mixing chamber includes one or more helical mixers 626.

[0092] Motor 610 and gearbox 612 drive reciprocating nozzle assembly 616 in a linear reciprocating motion. In one embodiment, the linear reciprocating motion is excited by an eccentric roller 628 coupled to the output shaft 630 of gearbox 612, the eccentric roller rotating within an annular support of comb 620. Driving pump 614 and reciprocating nozzle assembly 616 with a common motor 610 improves power efficiency, reduces weight and size, thereby improving the form factor of the formulation delivery device. However, some embodiments use more than one motor to drive pump 614 and reciprocating nozzle assembly 616.

[0093] Nozzle 618 is fluidly connected to a first fluid conduit 606 and a second fluid conduit 608 via a turbulent mixing chamber 632. This turbulent mixing chamber 632 mixes a first formulation drawn from the formulation cartridge via the first fluid conduit 606 with a second formulation drawn from the formulation cartridge via the second fluid conduit 608 to produce a mixed formulation. Specifically, the turbulent mixing chamber 632 mixes the two formulations by combining them under pressure in a common chamber and by allowing the two formulations to flow through one or more mixing elements that generate turbulent flow (as opposed to laminar flow) of the mixed formulation. The ratio of the first to the second formulation varies in different embodiments. For example, in some embodiments, the mixed formulation is a mixture of the first and second formulations in a ratio of approximately 0.8:1.0 to 1.2:1.0, such as 0.85, 0.90, 0.95, 1.00, 1.05, 1.10, or 1.15.

[0094] In some embodiments, a turbulent mixing chamber 632 is disposed between a pump 614 and a reciprocating nozzle assembly 616. In this configuration, the two formulations are mixed just before dispensing compared to mixing the formulation upstream of the pump 614, which produces a more uniform formulation viscosity and allows for better dispensing of the formulation from the nozzle 618.

[0095] In some embodiments, the turbulent mixing chamber 632 includes a helical mixer 626 disposed therein. Some embodiments include a plurality of helical mixers 626 fluidly connected in series along a fluid path within the turbulent mixing chamber 632 for improving mixing. In some embodiments, the outer diameter of each helical mixer is between 2.00 mm and 5.00 mm, for example, between 3.0 mm and 4.00 mm, for example, 3.18 mm. In some embodiments, the total length of each helical mixer is between 20.0 mm and 40.0 mm, for example, between 25.0 mm and 35.0 mm, for example, 33.0 mm. In some embodiments, the pitch of the length to diameter of each helical mixer (defined as total length / [outer diameter*#mixing element]) is between 0.75 and 1.25, for example, between 0.80 and 0.90, for example, 0.865. It has been found that the combination of the aforementioned specifications produces the optimal viscosity of the mixed formulation, especially when the two formulations are mixed only downstream of pump 614 and just upstream of reciprocating nozzle assembly 616, and particularly when pump 614 is a peristaltic pump.

[0096] In use, pump 614 draws formulation from a connected formulation cartridge via a first fluid conduit 606 and a second fluid conduit 608, through a turbulent mixing chamber 632, through a manifold 624, and through a nozzle 618. In the illustrated embodiment, the first fluid conduit 606 and the second fluid conduit 608 are kept fluid-separated before reaching downstream of pump 614 to prevent mixing of the two formulations before reaching the turbulent mixing chamber 632. As previously stated, mixing the two formulations before dispensing (i.e., between pump 614 and manifold 624) increases the viscosity of the mixed formulation.

[0097] Figures 8A to 10 A representative formulation cartridge 800 of a type compatible with any formulation delivery system, formulation delivery device, and formulation product line described herein is shown. However, the formulation delivery systems, formulation delivery devices, and formulation product lines described herein do not require the use of... Figures 8A to 10 The sustainable formulation cartridge 800 is shown.

[0098] The formulation cartridge 800 is a sustainable embodiment specifically designed to reduce waste and environmental impact while providing a user-friendly experience. To this end, the formulation cartridge 800 includes two main components: a handle portion 802 and a disposable refill pack 804 configured to reversibly slide into the handle portion 802. Historically, known cartridges have been designed to be completely disposed of after the formulation stored within is depleted, resulting in significant waste and higher consumer costs.

[0099] Compared to known cartridges, the formulation cartridge 800 is constructed such that the handle portion 802 can be reused indefinitely, and once the formulation stored within is depleted, only the disposable refill pack 804 needs to be discarded or recycled. Furthermore, each disposable refill pack 804 is configured to break down into smaller components, some of which can be recycled while others are discarded. Therefore, the formulation cartridge 800 utilizes an innovative structure to reduce waste and improve the user experience.

[0100] The handle portion 802 is sized, sized, and constructed to be repeatedly inserted into the cylinder of the dosage delivery device. Therefore, the handle portion 802 is formed of ABS plastic or a similar rigid polymer or other material and includes a hollow handle portion 802 and a tray portion 806, the hollow handle portion 802 being configured to receive a disposable refill pack 804 therein, the tray portion 806 extending away from the handle portion 802. In the representative embodiment shown, the handle portion 802 is a two-piece assembly (although it may be a single piece in other embodiments), and its size and sizing allow it to form a seamless extension of the dosage delivery device handle when fully inserted into the cylinder of the dosage delivery device handle. The tray portion 808 protrudes away from the handle portion 802 and has a U-shape configured to support the disposable refill pack 804 (e.g., the front body portion 810). For secure engagement and easy removal, the handle portion 802 includes a coupling tool for attaching the dosage cylinder 800 to the reusable handle of the dosage delivery device. A typical engagement tool includes a cartridge release 812 (e.g., a latch) formed in the handle portion 802, which engages the formulation delivery device when properly and fully inserted.

[0101] Single-use refill pack 804 stores a first formulation pack 814 and a second formulation pack 816, which respectively contain a first formulation 818 and a second formulation 820. Each of the first formulation pack 814 and the second formulation pack 816 has a volume between 40 mL and 70 mL, for example, 50 mL to 60 mL, or 55 mL. In some embodiments, the first formulation pack 814 and the second formulation pack 816 have different volumes.

[0102] The first formulation 818 and the second formulation 820 can each be any formulation described herein, such as a permanent hair dye; a semi-permanent hair dye; a developer; a hair conditioner; a hair growth care product, such as minoxidil; a hair protein care product; a disulfide bond repair hair care product; a fluid hair care product; a fluid scalp care product, etc. In some embodiments, the first formulation 818 and the second formulation 820 are different. For example, in some embodiments, the first formulation 818 is a hair dye and the second formulation 820 is a developer. In other embodiments, the first formulation 818 and the second formulation 820 are the same (e.g., a hair conditioner or a scalp care formulation).

[0103] like Figure 9 As shown, each formulation package includes a package 822 containing the formulation and a valve tool for selectively and fluidly connecting the disposable refill package to the dispensing nozzle unit of the formulation delivery device when the formulation cartridge 800 is received in the handheld formulation dispensing device. A representative valve tool includes a valve 824 through which the formulation exits the package 822. Representative formulation packages are described in International Patent Application PCT / US2018 / 052345, filed and assigned to L'Oreal SA on September 24, 2018, and U.S. Patent Application 17 / 133110, filed and assigned to L'Oreal SA on December 23, 2020, both of which are incorporated herein by reference in their entirety for all purposes.

[0104] The disposable refill pack 804 also includes a disposable elongated body portion 826 that provides structure for the disposable refill pack and includes a first formulation pack 814 and a second formulation pack 816. In some embodiments, the overall length of the body portion 826 is between 150 mm and 250 mm (e.g., 175 mm to 225 mm, 185 mm to 215 mm, 195 mm to 205 mm, or 200 mm), and the maximum cross-sectional dimension is 25 mm to 50 mm (e.g., 30 mm to 45 mm, 35 mm to 40 mm, or 36 mm). The body portion 826 has a rear body portion 828 and an elongated front body portion 810. The rear body portion 828 has a larger cross-sectional dimension than the front body portion 810 and is held within the handle portion 802 of the handle portion 802 during use (e.g., by friction engagement). The elongated front body portion 810 is supported by a tray portion 806 of the handle portion 802 and protrudes into the cavity of the formulation delivery device during use.

[0105] In the illustrated embodiment, the body portion 826 is made of recyclable material, such as structured paper (e.g., cardboard). In some embodiments where the body portion 826 is formed of paper, the paper has a weight between 8 and 12 points (e.g., 8.5, 9.0, 9.5, 10.0, 10.5, 11.0, or 11.5 points) to impart sufficient rigidity without producing excessive disposable material. In some such embodiments, the body portion 826 is formed from a single piece of recyclable material. As an example, in the illustrated embodiment, the body portion 826 is formed from a single sheet of paper. Figure 9 As shown, this folding structure forms an octagonal polygonal cross-section in the rear body portion 828 and a hexagonal polygonal cross-section in the front body portion 810. For ease of assembly, some embodiments of the body portion 826 include one or more notches or guide lines to ensure proper folding. The polygonal cross-sections of the illustrated embodiments are representative and not limiting. Other embodiments have triangular, rectangular, pentagonal, hexagonal, heptagonal, octagonal, or other polygonal cross-sectional shapes. In other embodiments, the body portion 826 has the shape and structure described herein, but it is not made of recyclable materials.

[0106] The optional packet sleeve 830 offers several important advantages. First, it provides a disposable refillable pack 804 for additional structures by sliding and reinforcing the front body portion 810. Therefore, in some embodiments, the sleeve 830 has a greater weight or thickness compared to the material forming the body portion 826; although this is not necessary. In some embodiments, the sleeve 830 is also formed of a recyclable material, which may be the same recyclable material as the body portion 826.

[0107] Second, the sleeve 830 is connected to the valve frame 832. For example, the sleeve 830 shown includes a plurality of engagement member recesses 834, which are configured to reversibly connect with engagement members of the valve frame 832.

[0108] Third, the sleeve 830 facilitates the disassembly of the single-use refill packaging 804. For example... Figure 8A and Figure 9 As shown, the sheath 830 includes an optional one-piece tear strip 836 (e.g., with perforations for a pull tab). In use, after the formulation is depleted, the user pulls the pull tab of the one-piece tear strip 836, thereby separating the valve frame 832 from the sheath 830. Upon completion of this action, the sheath 830 is retrieved, and the valve frame 832 is discarded. In some embodiments, the one-piece tear strip 836 is disposed on the body portion 826, for example, on the front body portion 810.

[0109] Although the sleeve 830 has several advantages, it is optional. In some embodiments, one or more of the features described above in the sleeve 830 are integrally formed in the body portion 826.

[0110] Valve frame 832 provides a rigid structure supporting dosage package valve 824 and encryption chip 838 for accurate and secure engagement with the dosage delivery device (and particularly with its dosage dispensing assembly) and for accurately positioning the encryption chip 838 near the cylindrical authentication interface of the dosage delivery device. Therefore, valve frame 832 is formed of ABS plastic, high-density polyethylene (HDPE), or other rigid polymers or other materials. A plurality of valve engagement units 840 extend through the front end of valve frame 832. Each valve engagement unit 840 receives and secures one of the dosage package valves 824. In some embodiments, valve engagement unit 840 has a valve orifice formed through a face of valve frame 832, the orifice being sized to receive the valve of the dosage package. To enable engagement with package 830 (or body portion 826 in some embodiments), valve frame 832 includes engagement members 842 (e.g., lugs) extending therefrom.

[0111] An encryption chip 838 is disposed on the disposable refill pack 804, for example, on the body portion 826 or on the valve frame 832 (as shown in the embodiment). The encryption chip 838 is positioned on the disposable refill pack 804 such that it is positioned to be read by its cartridge authentication interface when the dosage cartridge 800 is inserted into the dosage delivery device. Therefore, the encryption chip 838 stores information about the dosage cartridge 800 and its contents, such as at least one of the following: dosage identification, starting dosage, dosage expiration date, or dosage manufacturing date.

[0112] Therefore, the body portion 826, the sheath 830, the formulation package, and the valve frame 832 form a disposable refill package 804. In use, the disposable refill package 804 can be reversibly engaged with the handle portion 802, for example, by means of a frictional engagement between the disposable refill package 804 and the handle portion 802, and a retaining tool such as a connecting lug 844 on the body portion 826 or the sheath 830. When the disposable refill package 804 is inserted into the connecting lug 844, the connecting lug 844 engages and holds the handle portion 802 therein until it is forcibly pulled out of the handle portion 802. To further assist in holding the disposable refill package 804 within the handle portion 802, the illustrated handle portion 802 includes one or more optional retaining elements 846 (in this embodiment, deflectable lugs that engage the disposable refill package 804).

[0113] Figure 11 It shows Figure 11 The representative method 1100 of the present invention shown can be used with any formulation cartridge of the present invention, for example, Figures 8A to 10 The formulation cartridge is 800.

[0114] In block 1102, a depleted formulation cartridge is provided, i.e., a formulation cartridge in which the formulation package has been depleted of formulation. In some embodiments, the formulation cartridge is removed from the formulation delivery device, for example, by pressing the cartridge release and pulling the formulation cartridge out of the formulation delivery device.

[0115] In block 1104, the disposable refill pack is separated from the reusable cartridge body, for example, by pulling the disposable refill pack away from the reusable cartridge body with sufficient force to overcome the holding force exerted by the connecting lugs and retaining elements.

[0116] In optional block 1106, the recyclable portion of the disposable refill pack is separated from the non-recyclable portion of the disposable refill pack. For example, the valve frame and formulation pack are separated from the body portion and / or optional sleeve (in some embodiments, both of which are recyclable), for example, by tearing an integral tear tab on the sleeve or body portion and pulling the valve frame (along with the depleted formulation pack attached thereto) away from the sleeve and body portion.

[0117] In optional box 1108, the recyclable portion of the disposable refillable pack is recycled (i.e., the body portion and / or the sleeve), and the non-recyclable portion is discarded (i.e., the depleted formulation pack and valve frame).

[0118] In box 1110, insert a new disposable refill pack into the reusable tube body.

[0119] In box 1112, after inserting a new disposable refill pack into the reusable cartridge body, the reloaded formulation cartridge is inserted back into the formulation delivery device.

[0120] Therefore, the present invention not only provides a sustainable formulation cartridge, but also a method for using the formulation cartridge to further reduce waste and environmental impact.

[0121] Figure 12 A representative cleaning cartridge 1200 is shown, which has the same features as the previously described cleaning cartridge and is compatible with any formulation delivery system, formulation delivery device, and product line of the present invention. Therefore, the cleaning cartridge 1200 is not the same cartridge type as the formulation cartridge described herein (e.g., configured to be securely fitted into a reusable handle of a formulation delivery device, having the same shape and size, and multiple output nozzles).

[0122] The primary function of the cleaning cartridge 1200 is to be fluidly connected to the formulation delivery device and to provide a cleaning solution 1202 (e.g., water) as part of a cleaning procedure, which is then flushed through the formulation dispensing assembly. Therefore, the cleaning cartridge 1200 is a reusable component, having a body portion 1204 formed of ABS plastic or other suitable rigid polymer. The body portion 1204 supports a cleaning solution reservoir 1206, i.e., a tank, which stores the cleaning solution 1202, for example, 50 to 200 mL. The cleaning solution reservoir 1206 has a plurality of outlet nozzles 1208, which are sized and positioned to be fluidly connected to the fluid conduits of the formulation delivery device. A refill cap 1210 facilitates refilling of the cleaning solution reservoir 1206.

Unless otherwise specified, these quantities and numbers should not be considered limiting, but rather represent possible quantities or numbers in relation to this application. Furthermore, in this regard, the term "multiple" may be used to refer to quantities or numbers. In this respect, the term "multiple" means any number greater than one, such as two, three, four, five, etc. The terms "approximately," "approximately," "close to," etc., refer to values ​​within 5% above or below the stated value.
