[0017] The foregoing aspects and numerous related advantages of the claimed subject matter will be more readily appreciated by reference to the following detailed description, when taken in conjunction with the accompanying drawings. DETAILED DESCRIPTION

[0018] Disclosed are one or more methodologies or technologies that enable users to apply treatment formulations to human hair and scalp tissue. The following description provides representative examples that generally relate to hair and scalp treatment delivery systems and devices and formulation cartridges therefor. In one embodiment, it is advantageous for the treatment formulation to be applied to a targeted portion of the hair or scalp tissue. In one embodiment, application of a treatment formulation to a portion of the hair near the scalp is desired, for example, when applying a color dye to the roots of the hair during a color maintenance procedure.In another example, one approach requires applying a scalp treatment formulation directly to the scalp tissue, while minimizing contact with the hair.

[0019] Existing systems for applying treatment formulations to hair and scalp have been widely used. For example, hair coloring kits are typically used to alter the appearance of hair color or to fade gray hair, among other uses. Existing hair coloring systems have several disadvantages, including difficulty of use, a time-consuming process, uneven coverage, unpredictable results, excessive mess, etc. In one aspect, existing hair coloring systems may be ineffective at blending and coloring hair roots after new hair segments grow from the scalp, where the natural hair color differs from the remainder of the dyed hair. The present di- Dissemination aims to address these and other needs.

[0020] In some embodiments, the hair coloring formulation includes at least one tint and a separate developer, which are mixed in controlled proportions. However, in the present disclosure, the term "formulation" is not limited to the dye and the developer. As used herein, the term "formulation" generally refers to any of the dye, the developer, the formulation, the fluid, or any mixture thereof. In the present disclosure, the term "formulation" includes: a permanent hair dye; a semi-permanent hair dye; a developer; a conditioner; a hair growth treatment, such as minoxidil manufactured under the trade name ROGAINE®; a protein hair treatment; a disulfide bond repair hair treatment; a hair flow treatment; a scalp flow treatment, and the like.

[0021] Embodiments of the present disclosure are configured to apply the formulation to targeted areas of hair and scalp tissue. Although any of the aforementioned formulations are suitable for application using the embodiments described herein, the present disclosure generally refers to a hair coloring formulation such as that of the exemplary treatment formulation applied by the systems and devices described below. However, it will be appreciated that any of the systems, devices, cartridges, and methods may be used with any of the aforementioned formulations.

[0022] [Fig.l] illustrates a representative formulation delivery system 100 according to the present disclosure. The formulation delivery system 100 includes a number of different features, including a formulation product line 102, a formulation delivery device 104, and an optional application 106, which together enable a personalized user experience.

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

[0024] Thus, the common formulation cartridge type 110 allows a consumer to use many different formulations in a single formulation delivery device 104. A representative type of formulation cartridge 110 is described below in Figures 8A-10, and a representative cleaning cartridge 112 is described in [Fig. 12].

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

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

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

[0028] A representative type of formulation cartridge 110, which is configured to be inserted into the formulation delivery device 104 and to store a first formulation and a second formulation, is described below in Figures 8A-10.

[0029] The cleaning cartridge 112, which is of the common formulation cartridge type 110 (i.e., has a common exterior dimension and a plurality of liquid outlet nozzles), allows a user to clean the formulation delivery device 104 by performing a cleaning routine that flushes a cleaning liquid (e.g., water) from the cleaning cartridge 112 through the fluid conduits of the formulation delivery device 104, thereby removing residual formulation in the formulation delivery device 104. Advantageously, the cleaning cartridge 112 and the cleaning routine allow a significant portion of the formulation delivery device 104 to be reused for different formulations, thereby reducing waste and costs.

[0030] The cleaning cartridge 112 includes a refillable cleaning liquid reservoir disposed within the outer housing, which is fluidically connected to the plurality of outlet nozzles. Thus, a user can fill the cleaning liquid reservoir with a cleaning liquid such as water, perform a number of cleaning routines on the formulation delivery device 104, and refill the cleaning liquid reservoir.

[0031] The formulation delivery device 104 is a connected electromechanical apparatus that interacts with the user, with the formulation cartridges 110, and optionally with the application 106 to provide a personalized user experience. A representative formulation delivery device and its subsystems are described below in connection with Figures 4-7.

[0032] In general, the formulation delivery device 104 includes a reusable handle configured to receive the formulation cartridge type 110, and a formulation dispensing assembly and a controller, both of which are disposed in 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 the formulation or cleansing liquid from the formulation cartridge 110 and dispense it through the reciprocating nozzle assembly onto a hair portion, scalp portion, or body portion of a user.

[0033] The controller is configured to switch between at least one cleaning routine and one formulation routine in response to one or more inputs indicating that the cleaning cartridge or the formulation cartridge is inserted into the reusable handle. The controller communicates with an encryption chip reader of a cartridge authentication interface in the reusable handle to read an encryption chip disposed on the formulation cartridge 110, to authenticate which formulation 108 is stored in the formulation cartridge 110. formulation 110 that is inserted into the reusable handle at a given time. In some embodiments, the controller also authenticates when the cleaning cartridge 112 is inserted into the reusable handle. Based on the authenticated formulation 108 or cleaning cartridge 112, the controller causes the formulation delivery device 104 to execute a formulation routine that dispenses the authenticated formulation from the formulation cartridge through the formulation dispensing assembly. Based on the authenticated cleaning cartridge 112, the controller also causes the formulation delivery device 104 to execute a cleaning routine that dispenses the cleaning fluid through the formulation dispensing assembly.

[0034] The application 106 includes logic configured to operate on a non-transitory machine-readable storage medium, and includes modules that personalize the user experience, provide useful analytics, and enable e-commerce. The application 106 executes on a mobile device 114 such as a smartphone, tablet, or the like, and interacts with a user (e.g., an end user or a salon technician) to provide actionable information through a plurality of modules, which are described below in connection with [Fig. 3]. In some embodiments, the application 106 communicates with the formulation delivery device 104 and a network 116, such as a mobile network, a cloud-based enterprise network, a local area network, or the like.

[0035] Together, the formulation product line 102, the formulation delivery device 104, and the application 106 provide an enhanced and personalized user experience. Each of the foregoing elements of the formulation delivery system 100 will now be described in detail.

[0036] [Fig. 2] shows a schematic overview of a representative formulation delivery device 200, in order to facilitate understanding of some of its representative features. The formulation delivery device 200 should be understood as having the same features as the formulation delivery device 104 of [Fig. 1].

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

[0038] The power supply 212 is, in some embodiments, a direct current (DC) power supply, 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, the power supply 212 is an alternating current (AC) power supply, such as a common household AC outlet that uses an electrical cord (not shown) to electrically power the formulation delivery device 200.

[0039] The formulation dispensing assembly 214 delivers a formulation and / or a cleansing liquid from the formulation cartridge 110 to a 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 couples to a first liquid outlet nozzle of the formulation cartridge 110), a second fluid conduit fluidly connected to a second formulation inlet (which couples to a second liquid outlet nozzle of the formulation cartridge 110), a motor 218, a pump 220 driven by the motor 218, and a reciprocating nozzle assembly 222 that is also driven by the motor 218.

[0040] The cartridge authentication interface 210 is an RFID reader, near-field reader, or the like, which is positioned in the reusable handle 202 such that when the formulation cartridge 110 is inserted therein, the cartridge authentication interface 210 reads an encryption chip disposed on the formulation cartridge 224, in order to authenticate the formulation cartridge in connection with the formulation routine module 226 described below.

[0041] The optional position sensor 216 includes one or more sensors that, alone or collectively, help determine the position and orientation of the formulation delivery device 200 relative to a user's scalp or hair. In some embodiments, the position sensor 216 includes one or more accelerometers, touch sensors (e.g., capacitive touch sensors), proximity sensors (e.g., optical proximity sensors), or the like. The signals transmitted by the position sensor 216 are used by the controller 204, and certain modules thereof, to improve the accuracy and efficiency of formulation application to a user's hair or scalp.

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

[0043] In some embodiments, the controller 204 includes a communication interface having circuitry configured to enable communication with the formulation delivery system, including the formulation cartridge 224 (an encryption chip), the cleaning cartridge 228, the cartridge authentication interface 210, a mobile device and an application stored thereon, and / or another network element via the Internet, a cellular network, an RF network, a personal area network (PAN), a local area network, a wide area network, or another network. Accordingly, the communication interface may be configured to communicate using wireless protocols (e.g., WIFI®, WIMAX®, BLUETOOTH®, ZIGBEE®, cellular, infrared, near field, etc.) and / or wired protocols (universal serial bus or other serial communications such as RS-216, RJ-45, etc., parallel communication bus).In some embodiments, the communication interface includes circuitry configured to initiate a discovery protocol that allows the controller 204 and another network element (e.g., the formulation cartridge 110) to identify each other and exchange control information (e.g., the identity of the formulation stored in the formulation cartridge 110). In one embodiment, the communication interface has circuitry configured for a discovery protocol and to negotiate one or more pre-shared keys.

[0044] The data store 208 is a tangible, machine-readable storage medium that includes a mechanism that stores information in a non-transitory form accessible by a machine (e.g., the processor 206 or the mobile device 114). For example, a machine-readable storage medium includes recordable / non-recordable media (e.g., read-only memory (ROM), random access memory (RAM), magnetic disk storage media, optical storage media, flash memory devices, etc.)

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

[0046] The cartridge authentication module 230 communicates with the interface cartridge authentication interface 210 to authenticate any formulation cartridge 224 or cleaning cartridge 228 that is inserted into the reusable handle 202. For example, upon insertion of the formulation cartridge 224 into the reusable handle 202, the cartridge authentication interface 210 reads encrypted information from an encryption chip disposed on the formulation cartridge 224. If the cartridge authentication interface 210 successfully reads the encrypted information from the encryption chip, then the cartridge authentication module 230 “unlocks” the formulation delivery device 200, e.g., the formulation routine module 226. If, however, the cartridge authentication interface 210 cannot successfully authenticate the formulation cartridge inserted into the reusable handle 202, then it does not unlock the formulation delivery device 200.For example, if the formulation cartridge is a counterfeit cartridge or another cartridge containing an inferior formulation, then the cartridge authentication module 230 does not unlock the functionality of the formulation delivery device 200. In this way, the cartridge authentication module 230 beneficially prevents the user from suffering harm or having a bad experience.

[0047] The cartridge authentication module 230 is configured, in some embodiments, to read additional information from the encryption chip, including one or more of: a formulation identification, a starting formulation quantity, a formulation expiration date, or a formulation production date. In such embodiments, the cartridge authentication module 230 transmits the additional information to other modules for further use.

[0048] The formulation routine module 226 stores a plurality of formulation routines for different formulations (e.g., hair care formulation routines), and causes the formulation dispensing assembly 214 to execute one or more formulation routines, based on the formulation cartridge 224 authenticated by the cartridge authentication module 230. A formulation routine dispenses the authenticated formulation 108 from the formulation cartridge 224 through the reciprocating nozzle assembly 222.For example, a hair care formulation routine dispenses one or more hair care formulations from the reciprocating nozzle assembly 222, during a particular dispensing time, at a particular pump liquid flow rate, nozzle reciprocating frequency and / or reciprocating amplitude of the reciprocating nozzle assembly 222, and / or another device operating parameter specified by the formulation routine stored in the formulation routine module 226. In this way, the device . formulation delivery 200 adjusts one or more device operating parameters based on the specific formulation stored in the authenticated formulation cartridge 224 inserted into the formulation delivery device, for more effective treatment of the hair and scalp.

[0049] In some embodiments, the formulation routine module 226 determines, based on a dispensing time of the authenticated formulation, a dispensing volume of the authenticated formulation from the formulation cartridge through the formulation dispensing assembly. Based on the dispensing time and / or the dispensing volume, the formulation routine module 226 causes a visual indicator on the reusable handle 202 to signal a remaining amount of formulation. This helps the user anticipate when the formulation cartridge will need to be replaced and prompts the user to use the e-commerce module of the connected application to conveniently procure additional formulation cartridges.

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

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

[0052] According to a method of the present disclosure, a method of cleaning any of the formulation delivery devices includes inserting the cleaning cartridge at least partially filled with the cleaning liquid into the reusable handle of the formulation delivery device, and performing the cleaning routine until the cleaning fluid dispensed from the formulation delivery assembly is clear.

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

[0054] The sleep / wake-up module 236 manages whether the formulation delivery device 200 is in a wake-up or sleep state. The formulation delivery device 200 is in a sleep state by default, whereby little or no power is supplied 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 is unable to execute a formulation routine or a cleaning routine. In the wake-up state, by comparison, the controller 204, the cartridge authentication interface 210, the formulation dispensing assembly 214, and the position sensor 216 are sufficiently powered for the formulation delivery device 204 to be able to execute one or more formulation routines or cleaning routines.In some embodiments, the formulation delivery device 104 is "awakened," i.e., brought from the sleep state to the wake state, by: pressing a button disposed on the reusable handle 202, or by inserting a formulation cartridge 224 or a cleaning cartridge 228 into the reusable handle 202. In some embodiments, the formulation delivery device 200 returns to the sleep state after a predetermined period of inactivity (e.g., 120 seconds of inactivity).

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

[0056] [Fig. 3] shows a schematic overview of a representative application 300, which should be understood to have all the features of the application 106 of [Fig. 1] and which is compatible with all formulation delivery systems and formulation delivery devices of the present disclosure. As indicated above, the application 300 is configured to operate on a device, for example, a mobile device such as a smartphone or a tablet. As a representative example, the application 300 is described in the context of a mobile device 302 connected to a 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 store 310 storing a plurality of modules. The terms "processor," "data store," and "module" have the same meanings as described above with respect to the controller 204, and as used below in connection with representative formulation delivery devices.

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

[0059] The application 300 includes a number of modules that customize the user experience, including a user profile module 312 and a user routine module 314. The modules described below are representative and not limiting. Accordingly, some embodiments of the application 300 include additional modules, while other embodiments include fewer modules.

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

[0061] In some embodiments, the user profile module 312 communicates with the user routine module 314 by providing one or more of the user profile inputs, or an entire user profile, to the user routine module 314. The User routine module 314 then uses one or more of the user profile inputs to create one or more user-specific routines and / or to select one or more tutorials to be presented on 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 of a formulation routine (e.g., flow rate, dispensing time, reciprocating amplitude, or reciprocating frequency) generated by the formulation routine module based on one or more of the user profile inputs.

[0063] The user routine module 314 assists the user in effectively using the connected formulation delivery device by formulating, in some embodiments, one or more user-specific routines for each user based on one or more user profile inputs. In other words, the user routine module 314 creates a new formulation routine (rather than selecting a predetermined formulation routine) to effectively treat one or more conditions identified by the user profile inputs or achieve one or more goals identified by the user profile inputs.As a representative example, when user inputs indicate that the user's hair is both color-treated and damaged, the user routine module 314 creates a user-specific routine that selects a hair repair formulation and a shampoo formulation appropriate for the user's hair color from the formulation product line, and displays the user-specific routine (e.g., as instructions) to use the selected hair repair formulation and shampoo at a determined interval to improve the health of the user's hair.

[0064] Further, the user routine module 314 displays on the display 306: a) one or more passive tutorials for the formulation routines, the cleaning routines and / or the calibration routines; 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 routine module 314 receives one or more of the user profile inputs, or an entire user profile, from the user profile module 312, and then displays a passive tutorial (e.g., a pre-recorded instructional video) that is targeted to the user based on the received user profile inputs or the user profile. As an example, the user routine module 314 receives a user profile input from the user profile module 312 indicating that the user has colored 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 routine module 314 receives one or more position signals from the position sensor of the formulation delivery device via the controller. Based on the received position signals, the user routine module 314 provides instructions to the user on how to operate the formulation delivery device when the user is using the device (e.g., instructions to move the formulation delivery device in a particular direction, at a particular speed, in a particular pattern, toward a particular spatial boundary).As an example, the user routine module 314 receives a position signal from the position sensor indicating that the formulation delivery device is positioned at the user's left temple; based on this received position signal, the user routine module 314 displays a video instructing the user to apply a scalp treatment formulation by moving the formulation delivery device from the left temple to the right temple while dispensing the scalp treatment formulation.

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

[0068] The calibration module 318 assists the user in calibrating the formulation delivery device, thereby increasing the efficiency of the formulation routines performed by the formulation delivery device. In some embodiments, the calibration module 318 displays a passive tutorial (e.g., a pre-recorded instructional video) that instructs the user on how to perform a calibration routine. In some embodiments, the calibration module 318 provides one or more sets of active instructions that instruct how to use and perform the calibration routine when the user uses the formulation delivery device, and when the calibration module 318 receives position signals from the formulation delivery device.

[0069] According to a representative calibration routine, the calibration module 318 instructs the user to position the formulation delivery device at a plurality of calibration locations of a portion of the user's body, e.g., in a particular order (e.g., a left temple, then a right temple, then a front hairline, then a back hairline). The user then moves the formulation delivery device to each of the calibration locations, indicating by pressing a button on the formulation delivery device or by other action when the formulation delivery device is at the specified calibration location, and / or when the user has moved the formulation delivery device from one calibration location to another.

[0070] Based on the position signals received from the position sensor of the formulation delivery device, the calibration module 318 and / or the formulation delivery device register the calibration locations. Then, the calibration module 318 and / or the formulation delivery device adjust one or more user-specific routines based on the registered calibration locations. In some embodiments, this adjustment step includes adjusting a spatial boundary and / or a temporal duration of one or more formulation routines stored in the formulation routine module).

[0071] The manual adjustment module 320 allows a user 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), thereby providing greater control of the formulation delivery device and a more personalized user experience. Accordingly, the manual adjustment module 320 has a user interface with one or more virtual, user-adjustable sliding scales, switches, editable value fields, and the like, which are configured to receive one or more operating parameter inputs from the user.The manual adjustment module 320 receives the operating parameter inputs and transmits said operating parameter inputs to the formulation delivery device (e.g., the formulation routine module), which adjusts the corresponding device operating parameter based on the corresponding operating parameter input (e.g., to match the operating parameter input).

[0072] The analytics module 322 receives device operating parameters (e.g., from the formulation delivery device) and calculates useful analytics, which the analytics module 322 then provides to the user via the user interface and / or to a third party via the network 304. Representative analytics include: a formulation usage pattern, a formulation purchase prediction, and diagnostics of the formulation delivery device. In some embodiments, the analytics module 322 communicates with the network 304 (e.g., an analytics platform disposed on one or more cloud servers) to retrieve additional information and / or to calculate said analytics.

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

[0074] The formula creation module 324 allows a user to create a customized formula based on the user's selection of one or more formulation inputs, which correspond to one or more desired outcomes (e.g., desired hair color), one or more formulation inputs (e.g., an indication that the user's hair is damaged), and / or one or more user profile inputs provided to the user profile module 312. Accordingly, the formula creation module 324 is configured to receive one or more user profile inputs from the user profile module 312, and to formulate a customized formulation based on those inputs.

[0075] To facilitate the creation of the custom formulation by the user, the formula creation module 324 provides a user interface with one or more virtual, user-adjustable sliding scales, switches, editable value fields, and the like, corresponding to each formulation entry. In some embodiments, the formula creation module 324 communicates with the network 304 (e.g., a formulation database located on one or more cloud servers) to retrieve additional information and / or to formulate said custom formulation.

[0076] The e-commerce module 316 presents a purchasing interface that allows a user to purchase (such as on a one-time or subscription basis) products related to the formulation delivery device. In some embodiments, the e-commerce module 316 retrieves one or more customized formulations from the formula creation module 324 (or components thereof) and presents on the purchasing interface an option for the user to purchase one or more formulation cartridges 110 containing the customized formulation.In some embodiments, the e-commerce module 316 retrieves one or more user profile entries and / or user-specific routine entries from the user profile module 312 and presents on the purchasing interface an option for the user to purchase one or more formulation cartridges containing the formulations that target the user profile entries (e.g., when the user entries indicate damaged hair, a formulation cartridge containing a hair repair formulation). In some embodiments, the e-commerce module 316 presents on the purchasing interface an option to purchase the cleaning cartridge 112 or the device. formulation delivery device 104 and / or their components. This purchasing interface and purchasing options may be based on a formulation usage model and / or a formulation purchase prediction retrieved from the analysis module 322.

[0077] Figures 4 and 5 show a representative formulation delivery device 400, and its components, in accordance with one embodiment of the present disclosure. The formulation delivery device 400 is configured to receive one type of formulation cartridge 402 (including a cleaning cartridge of the same type). One embodiment of a formulation cartridge of the formulation cartridge type 402 is described below in detail in connection with Figures 8A-10; the formulation cartridge 402 shown in [Fig. 4] should be understood as having the same features as described therein.Some embodiments of the formulation delivery device 400 include the formulation cartridge 402 and / or an optional passage 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, and in some embodiments is an assembly formed of a plurality of shells configured to be joined together with fasteners such as snaps, screws, or the like. The reusable handle 406 has an elongated, hollow gripping portion having a cartridge cavity therein that is sized to receive the formulation cartridge type 02. In some embodiments, the cavity includes keying features that facilitate proper insertion of the formulation cartridge type 402.For example, some embodiments include a cartridge interface 408 disposed in the opening and having a flat docking surface that interfaces with a corresponding docking surface of the formulation cartridge 402 when properly inserted into the opening.

[0079] The reusable handle 406 houses a formulation dispensing assembly 410 (described below in connection with Figures 5-7), in addition to a controller 412. The formulation dispensing assembly 410 and the controller 412 have the same features as the formulation dispensing assembly 214 and the controller 204 of [Fig. 2], respectively. One embodiment of a formulation dispensing assembly is described below in detail in connection with Figures 6 and 7; the formulation dispensing assembly 410 shown in [Fig. 4] should be understood to have the same features as described therein.

[0080] The formulation dispensing assembly 410 dispenses a formulation or cleaning liquid from the formulation cartridge 402, and includes a pump, fluid conduits, a mixing chamber, and a nozzle assembly. reciprocating nozzle assembly 414 (described below) with nozzles that extend away from the forward end of the reusable handle 406 between a plurality of optional spacer portions 416. The reciprocating nozzle assembly 414 includes a plurality of annular nozzles that reciprocate back and forth along a groove of the reusable handle 406 while dispensing a formulation onto a user's skin or hair. In some embodiments, the reciprocating nozzle assembly 414 reciprocates at a reciprocating amplitude of 7.0 to 12.0 mm (e.g., 8.0 mm to 11.0 mm, or 9.0 to 10.0 mm) and / or at a reciprocating frequency of 5.0 Hz to 10.0 Hz (e.g., 6.0 Hz to 9.0 Hz, 6.0 Hz to 8.0 Hz), which are adjustable by the formulation routine module, the cleaning routine module, the user routine module, the manual adjustment module, or another module.

[0081] As shown in [Fig. 5], the formulation cartridge 402 has one or more containers (e.g., pouches or packets) of formulation 418 disposed therein, each of which has an outlet nozzle 420 protruding through a distal (front) end of the formulation cartridge 402 in a configuration that fluidly connects 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 disposed on the reusable handle 406 and electrically connected to the controller 412 activates the features of the formulation delivery device 400 described above. In some embodiments, pressing the button 426 activates the features of any of the modules described above in [Fig. 2]. For example, in some embodiments, pressing the button 426 activates a sleep / wake module stored in the controller 412, thereby waking the formulation delivery device 400 from a sleep state to a wake state. In some embodiments, pressing the button 426 while a formulation cartridge is inserted into the reusable handle 406 activates a formulation routine module stored in the controller 412, thereby initiating a formulation routine.

[0083] In some embodiments, pressing button 426 while a cleaning cartridge is inserted into reusable handle 406 activates a cleaning routine module stored in controller 412, thereby initiating a cleaning routine. Visual indicators 428 (e.g., LEDs) disposed along reusable handle 406 indicate one or more of the amount of formulation remaining or the remaining battery life, e.g., based on a dispensing time determined by the formulation routine module of the controller. Some embodiments include additional buttons and / or a different number of visual indicators 428 with different functionalities, and the illustrated embodiment is 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 formulation cartridge.

[0084] The controller 412 includes logic (stored in a data store thereof) that, when executed by a processor of the controller 412, causes a cartridge authentication interface 430 disposed in the reusable handle 406 (e.g., an RFID reader) to read an encryption chip 432 on the formulation cartridge 402 to authenticate the formulation cartridge 402. The encryption chip 432 stores at least one of the formulation cartridge 402, a formulation identification, a starting formulation quantity, a formulation expiration date, or a formulation production date.

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

[0086] In some embodiments, the controller 412 also includes logic that, when executed, causes the formulation delivery device to execute, based on authentication of a cleaning cartridge inserted into the reusable handle, a cleaning routine that dispenses a cleaning liquid through the formulation dispensing assembly. For example, the formulation delivery device authenticates a cleaning cartridge inserted into the reusable handle, and then, in response to pressing a button on the reusable handle, executes a cleaning routine that causes the formulation dispensing assembly 410 to continuously or continually dispense a cleaning liquid (e.g., water) from the reciprocating nozzle assembly at one or more of the device operating parameters. following predetermined rates, while the button is pressed: a cleaning fluid flow rate, a reciprocating frequency, or a reciprocating amplitude. In some embodiments, the cleaning fluid flow rate is higher than any formulation flow rate of one or more of the formulation routines stored in the controller 412, which has the advantage of efficiently flushing residual formulation from the formulation dispensing assembly.

[0087] The passage adapter 404 attaches to the reusable handle 406 on the reciprocating nozzle assembly 414. In some embodiments, the passage adapter 404 provides an audible feedback signal upon proper engagement with the reusable handle 406.

[0088] Figures 6 and 7 show a representative formulation dispensing assembly 600, which is compatible with any of the formulation delivery devices, formulation cartridges, and cleaning cartridges described herein. The primary function of the formulation dispensing assembly 600 is to dispense a mixed formulation of two different formulations from a formulation cartridge onto a user's skin or hair. In some embodiments, the formulation dispensing assembly 600 dispenses the mixed formulation at a rate of 20 to 40 mL / min or 120 mL every minute, e.g., 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 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 with projections extending rearwardly (i.e., toward the cartridge cavity when disposed in the reusable handle) from the first fluid conduit and the second fluid conduit, respectively, toward a rear end of the reusable handle, the projections being configured to protrude into the formulation cartridge.

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

[0091] A reciprocating nozzle assembly 616 includes a plurality of annular nozzles 618 disposed on a comb 620 which, in use, performs a reciprocating motion back and forth along a groove of the reusable handle 406 while dispensing the formulation onto a user's skin or hair, to achieve more uniform formulation coverage. Each of the nozzles 618 includes a formulation channel 622, each of which is fluidly connected to the first fluid conduit 606 and the second fluid conduit 608 via the manifold 624. In some embodiments, each formulation channel 622 is tapered, which has the advantage of increasing the formulation dispensing speed and / or further mixing the two formulations. The tapered formulation channel has been found to be advantageous when used in combination with other features described herein, for example, when the pump 614 is a peristaltic pump and / or when the turbulent mixing chamber includes one or more helical mixers 626.

[0092] The motor 610 and the gearbox 612 drive the reciprocating nozzle assembly 616 in a linear reciprocating motion. In one embodiment, the linear reciprocating motion is motivated by an eccentric roller 628 coupled to an output shaft 630 of the gearbox 612, which eccentric roller 628 rotates within an annular support of the comb 620. Driving the pump 614 and the reciprocating nozzle assembly 616 by a common motor 610 improves energy 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 the pump 614 and the reciprocating nozzle assembly 616.

[0093] The nozzles 618 are fluidically connected to the first fluid conduit 606 and the second fluid conduit 608 via a turbulent mixing chamber 632, which 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 create a mixed formulation. In particular, the turbulent mixing chamber 632 mixes the two formulations by combining them in a common chamber under pressure, and flowing the two formulations past one or more mixing elements, which create a turbulent flow of the mixed formulation (as opposed to a laminar flow). The proportions of the first formulation relative to the second formulation vary depending on the embodiments.For example, in some embodiments, the blended formulation is a mixture of a first formulation and a second formulation at a ratio of about 0.8:1.0 to 1.2:1.0, e.g., 0.85, 0.90, 0.95, 1.00, 1.05, 1.10, or 1.15.

[0094] In some embodiments, the turbulent mixing chamber 632 is disposed between the pump 614 and the reciprocating nozzle assembly 616. In this configuration, the two formulations are mixed just prior to dispensing, which creates a more uniform formulation consistency and results in better formulation distribution from the nozzles 618, compared to mixing the formulations upstream of the pump 614.

[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 enhanced mixing. In some embodiments, each helical mixer has an outer diameter of between 2.00 mm and 5.00 mm, e.g., between 3.00 mm and 4.00 mm, e.g., 3.18 mm. In some embodiments, each helical mixer has an overall length of between 20.0 mm and 40.0 mm, e.g., between 25.0 mm and 35.0 mm, e.g., 33.0 mm. In some embodiments, each helical mixer has a length-diameter pitch (defined as total length / [outer diameter * # mixing elements]) of between 0.75 and 1.25, e.g., between 0.80 and 0.90, e.g., 0.865.It has been found that the combination of the foregoing specifications produces the best mixed formulation consistency, particularly when the two formulations are mixed only downstream of pump 614, just upstream of reciprocating nozzle assembly 616, and also when pump 614 is a peristaltic pump.

[0096] In use, the pump 614 draws the formulation from the connected formulation cartridge, through the first fluid conduit 606 and the second fluid conduit 608, through the turbulent mixing chamber 632, through the manifold 624, and through the nozzles 618. In the illustrated embodiment, the first fluid conduit 606 and the second fluid conduit 608 are kept fluidly separate until downstream of the pump 614, to prevent mixing of the two formulations until the turbulent mixing chamber 632. As previously indicated, mixing the two formulations just prior to dispensing (i.e., between the pump 614 and the manifold 624), improves the consistency of the mixed formulation.

[0097] Figures 8A-10 show a formulation cartridge 800 representative of a type of formulation cartridge that is compatible with any of the formulation delivery systems, formulation delivery devices, and formulation product lines described herein. However, the formulation delivery systems, formulation delivery devices, and formulation product lines described herein are not required to use the durable formulation cartridge 800 shown in Figures 8A-10.

[0098] The 800 formulation cartridge is a sustainable embodiment specifically designed to reduce waste and environmental impact, while delivering an ex user-friendly experience. To this end, the formulation cartridge 800 includes two main components: a handle portion 802 and a disposable formulation cartridge refill unit 804 (hereinafter simply refill unit 804) configured to reversibly slide into the handle portion 802. Historically, known cartridges have been designed to be entirely discarded after the formulation stored inside is depleted, resulting in significant waste and higher cost to the consumer.

[0099] Unlike known cartridges, the formulation cartridge 800 is constructed such that the handle portion 802 can be reused indefinitely and only the refill units 804 can be readily replaced after the formulation stored therein is depleted. Further, each refill unit 804 is configured to be broken down into smaller components, some of which can be recycled in some embodiments and others discarded. Thus, the formulation cartridge 800 utilizes an innovative structure to reduce waste and enhance the user experience.

[0100] The handle portion 802 is sized and constructed to be repeatedly inserted into the cartridge cavity of the formulation delivery device. Accordingly, the handle portion 802 is formed of ABS plastic or a similar rigid polymer or other material and includes a hollow handle portion 802 configured to receive the refill unit 804 therein, and a tray portion 806 that extends away from the handle portion 802. The handle portion 802 is a two-piece assembly in the representative embodiment shown (although it may be a single piece in other embodiments), and is sized such that it forms a seamless extension of the handle of the formulation delivery device when fully inserted into a cartridge cavity thereof.The tray portion 808 protrudes away from the handle portion 802 and has a U-shape configured to support the refill unit 804 (e.g., the front body portion 810). To facilitate secure engagement and easy removal, the handle portion 802 includes coupling means for coupling the formulation cartridge 800 to a reusable handle of a formulation delivery device. Representative coupling means include a cartridge release device 812 (e.g., a latch) formed in the handle portion 802, which engages with the formulation delivery device upon proper and complete insertion.

[0101] As best shown in [Fig. 9A], the refill unit 804 generally includes a refill pack comprising a shell 826 enclosing at least one formulation container (e.g., a pack, pouch, or other container), e.g., a first formulation pouch 814 and a second formulation pouch 816, and a valve frame 832 coupled to the refill pack, e.g., a front body portion 810 of the shell 826. The first formulation pouch 814 and the second formulation pouch 816 contain a first formulation 818 and a second formulation 820, respectively. The refill unit 804 may optionally include a pack sleeve 830.

[0102] Each of the first formulation bag 814 and the second formulation bag 816 has a volume of about 40 mL to about 70 mL, about 50 mL to about 60 mL, about 40 mL to about 65 mL, about 40 mL to about 60 mL, about 40 mL to about 55 mL, about 40 mL to about 50 mL, about 45 mL to about 70 mL, about 50 mL to about 70 mL, about 55 mL to about 70 mL, about 60 mL to about 70 mL, or about 55 mL. In some embodiments, the first formulation bag 814 and the second formulation bag 816 have different volumes. In some embodiments, the refill unit 804 stores only one formulation container.

[0103] The first formulation 818 and the second formulation 820 may each be any of the formulations described herein, for example, a permanent hair dye; a semi-permanent hair dye; a developer; a conditioner; a hair growth treatment, such as minoxidil; a protein hair treatment; a disulfide bond repair hair treatment; a flowable hair treatment; a flowable scalp treatment, or the like. 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 conditioner or scalp treatment formulation).

[0104] As shown in [Fig. 9A], each formulation pouch 814, 816 includes a package 822 containing a formulation and valve means for selectively fluidly coupling the refill unit to a dispensing nozzle unit of a formulation delivery device when the formulation cartridge 800 is received in the hand-held formulation delivery device. Representative valve means include a valve 824 through which the formulation exits the package 822. Representative formulation containers are described in International Patent Application Publication No. 2019 / 067336A2, published on April 4, 2019 and assigned to L'Oréal SA, and in Patent Application Publication No. 2021 / 0196021A1, published on July 1, 2021, and assigned to L'Oréal SA.

[0105] The shell 826 has an elongated shape sized to be received within the reusable handle portion 802. The shell 826 encloses and protects the first fore pocket. formulation 814 and the second formulation bag 816 and engages the valve frame 832 (described below). Thus, the shell 826 functions as a package that protects the formulation bags 814, 816 during commerce prior to loading into the formulation delivery device.

[0106] In some embodiments, the shell 826 has an overall length of 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 a maximum cross-sectional dimension of 25 mm to 50 mm (e.g., 30 mm to 45 mm, 35 mm to 40 mm or 36 mm). The shell 826 has a rear body portion 828 and a thin front body portion 810, e.g., a neck portion, extending away from the body portion 828. The body portion 828 and the thin front body portion 810 generally align in a common longitudinal direction to permit assembly with the reusable handle portion 802, and to permit insertion into the cartridge cavity of the formulation delivery device.

[0107] In some embodiments, the shell 826 is constructed at least partially from a recyclable or recycled material, e.g., a paper material such as an injection-molded paper material or a die-cut structured paper (e.g., cardboard). In the illustrated embodiment, the shell 826 is formed from a single piece of injection-molded paper material. In some embodiments in which the shell 826 is formed from paper, the paper has a weight of between 8 and 12 points (e.g., 8.5 points, 9.0 points, 9.5 points, 10.0 points, 10.5 points, 11.0 points, or 11.5 points), to provide sufficient stiffness without contributing to excess disposable material.

[0108] The rear body portion 828 of the shell 826 has a larger cross-sectional dimension than the front body portion 810 when viewed in a plane normal to the longitudinal direction of the cartridge 800. A hump or bulge 827 gives the rear body portion 828 a larger cross-sectional area than the front body portion 810. Advantageously, the hump or bulge 827 allows formulation pouches 814, 816 of larger volume to be used. In addition, the hump or bulge 827 forms a stop 829 which abuts against a corresponding inner face of the handle portion 802 and secures the longitudinal position of the shell 826 during use.

[0109] The thin front body portion 810 of the shell 826 is sized to fit within the tray portion 806 of the handle portion 802 and to protrude into the cartridge cavity of the formulation delivery device during use. As best shown in [Fig. 8A], the front body portion 810 mates with the valve frame 832. To facilitate secure connection and alignment with the valve frame 832, the front body portion 810 includes means valve frame coupling, e.g., at least one coupling tab 844 configured to selectively engage the valve frame 832. In the illustrated embodiment, the front body portion 810 includes a single coupling tab 844 extending away from a front end thereof. The coupling tab 844 includes an engagement feature, e.g., a notch or raised protrusion 831 shaped and sized to engage a complementary opening 833 of the valve frame 832.

[0110] The shell 806 may have many different configurations. For example, referring to Figures 9A and 9B together, the illustrated shell 806 is a double-shell configuration formed with at least two partial shells (in this embodiment, two halves 835, 837) hingedly coupled by a hinge 839, e.g., a living hinge integrally formed with the two halves. In the shown embodiment, the hinge 839 is disposed at the distal end of the shell 806, i.e., at a distal end of each of the halves 835, 837. In other embodiments, the hinge may be disposed at a different location, e.g., along a longitudinal edge of the halves. In some embodiments, shell 806 includes a different number of partial shells, e.g., three or four partial shells that assemble to enclose formulation pockets 814, 816.In still other embodiments, the shell 806 comprises a single piece forming an open-ended tube into which the formulation pockets 814, 816 can be inserted.

[0111] Alignment of halves 835, 837 allows proper attachment of the body portion front 810 to the valve frame 832. To this end, as best shown in FIG. 3B, the halves 835, 837 optionally include complementary alignment means 841a-d, e.g., complementary tabs and slots. The alignment means shown are representative and not limiting. In other embodiments, the alignment means may include different fasteners, e.g., hook and loop fasteners. In still other embodiments, the partial shells may be configured to align with each other by friction or other means. In addition to aligning the halves, the alignment means 841a-d help hold the halves together.

[0112] Although the illustrated shell 826 is formed from an injection-molded paper material, this construction is representative and not limiting. In some embodiments, the shell 826 is formed from a single die-cut piece of paper, which is folded to provide a three-dimensional structure having a rear body portion 828 and a thin neck portion 810 extending away therefrom. In some such embodiments, this folded construction creates a polygonal cut in the rear body portion 828 and a polygonal cut in the front body portion 810 (e.g., octagonal and hexagonal cross-sections, respectively). To facilitate assembly, some of these embodiments of the shell 826 include one or more partitions or guidelines that ensure proper folding. Some embodiments have a cross-section that is triangular, rectangular, pentagonal, hexagonal, heptagonal, octagonal, or other polygonal shape.

[0113] The optional pack sleeve 830 slides over the neck portion 810 and provides several important advantages. First, it provides additional structure to the refill unit 804 by sliding over and reinforcing the front body portion 810. Therefore, in some embodiments, the pack sleeve 830 has a greater weight or thickness relative to the material that forms the shell 826, although this is not required. In some embodiments, the pack sleeve 830 is also formed from a recyclable material, which may be the same recyclable material as the shell 826.

[0114] Second, in some embodiments, the pack sleeve 830 mates with the valve frame 832. For example, the illustrated pack sleeve 830 includes a plurality of engagement member recesses 834 configured to reversibly mate with engagement members of the valve frame 832.

[0115] Third, the pack sleeve 830 facilitates disassembly of the refill unit 804. As shown in [Fig. 8A] and Fig. 9, in some embodiments, the pack sleeve 830 includes an optional integral tear 836a formed thereon (e.g., a perforation with a pull tab). In other embodiments, the tear is formed on the neck portion 810 (see tear 836b). In use, once the formulation packs 814, 816 are depleted, a user pulls the pull tab of the integral tear 836a and / or 836b, thereby separating the valve frame 832 from the pack sleeve 830. Once this action is complete, the pack sleeve 830 is recycled and the valve frame 832 is discarded. In some embodiments, the integral tear 836 is disposed on the shell 826, e.g., the front body portion 810.

[0116] The valve frame 832 provides a rigid structure that aligns the valves 824 of the formulation bag for proper fluid interconnection with the fluid conduits of the formulation delivery device. Further, in some embodiments, the valve frame 832 supports an optional encryption chip 838 as described above. In such embodiments, the valve frame 832 is sized and shaped to accurately position the encryption chip 838 adjacent the authentication interface of the formulation delivery device cartridge when the formulation cartridge 800 is disposed in the handle of the formulation delivery device. Therefore, the valve frame 832 is formed from ABS plastic, HDPE, or another rigid polymer or material. In some embodiments, the valve frame 832 is formed from the same material as the shell 806.

[0117] A plurality of valve engagement units 840 extend through a forward end of the valve frame 832. Each valve engagement unit 840 receives and secures one of the formulation bag valves 824. In some embodiments, the valve engagement unit 840 is a valve opening or cutout disposed through a face of the valve frame 832, the valve opening or cutout being sized to receive a valve of a formulation bag and optionally to engage an outer circumference of the valve. To enable coupling with the pack sleeve 830 (or shell 826 in some embodiments), the valve frame 832 includes optional engagement members 842 (e.g., tabs) extending therefrom. In some embodiments, the valve frame 832 engages the forward body portion 810 by a friction fit.

[0118] The encryption chip 838 (e.g., an RFID tag) is disposed on the refill unit 804, e.g., on the body portion 826 or on the valve frame 832 (as in the illustrated embodiment). The encryption chip 838 is positioned on the refill unit 804 such that when the formulation cartridge 800 is inserted into the formulation dispensing device, it is positioned to be read by the cartridge authentication interface. Accordingly, the encryption chip 838 stores information regarding the formulation cartridge 800 and its contents, e.g., at least one of a formulation identification, a starting formulation quantity, a formulation expiration date, or a formulation production date.

[0119] Thus, the shell 826, the formulation pouches 814, 816, the valve frame 832 and the optional pack sleeve 830 form the refill unit 804. In use, the refill unit 804 may be reversibly coupled to the handle portion 802, for example, by securing means such as coupling tabs on the shell 826 or a friction fit between the refill unit 804 and the handle portion 802.

[0120] [Fig. 11] shows representative methods 1100 that may be used with any of the formulation cartridges of the present disclosure, for example, the formulation cartridge 800 of Figures 8A-10. By way of example, [Fig. 11] shows methods of replenishing or refilling formulation cartridges of the present disclosure.

[0121] In step 1102, a formulation cartridge is provided, for example, a cartridge of formulation configured to provide at least one formulation to a formulation delivery device. In some embodiments, the formulation cartridge includes a formulation pouch that is emptied of its formulation. In some embodiments, the formulation cartridge is removed from a formulation delivery device, for example, by pressing a cartridge release device and pulling the formulation cartridge out of the formulation delivery device. In any embodiment, the formulation cartridge includes a reusable body or handle and a formulation cartridge refill unit, which may include a valve frame engaging a refill pack storing the at least one formulation. In any embodiment, the refill pack includes a shell enclosing at least one container storing the at least one formulation.

[0122] In step 1104, the formulation cartridge refill unit is separated from the reusable handle. In some embodiments, the reusable handle is disassembled into two or more parts, thereby revealing at least a portion of the formulation cartridge refill unit, and then removing the formulation cartridge refill unit from the disassembled reusable handle.

[0123] In optional step 1106, the formulation cartridge refill unit is at least partially disassembled, e.g., by separating the refill pack from the valve frame (such as by separating at least one formulation container from a shell). In some embodiments, a recyclable portion of the refill unit is separated from a non-recyclable portion of the refill unit. For example, the valve frame and formulation pouches are separated from the body portion and / or the optional pack sleeve (both recyclable in some embodiments), e.g., by tearing an integral tear on the pack sleeve or the body portion and pulling the valve frame (and the spent formulation pouches secured thereto) away from the pack sleeve and the body portion.

[0124] In optional step 1108, the recyclable portion(s) of the disposable refill unit are recycled (i.e., the body portion, the valve frame, and / or the pack sleeve), and the non-recyclable portion(s) are discarded (i.e., the spent formulation pouches and the valve frame).

[0125] In step 1110, a new disposable refill unit is inserted into the reusable cartridge handle.

[0126] In step 1112, the refilled formulation cartridge is inserted back into the formulation delivery device after inserting the new disposable refill unit into the reusable cartridge handle.

[0127] Thus, the present disclosure provides not only durable formulation cartridges, but also methods of using the same to further reduce waste and environmental impact.

[0128] [Fig. 12] shows a representative cleaning cartridge 1200, which has the same features as the cleaning cartridges described previously, and which is compatible with any formulation delivery system, formulation delivery device and product line of the present disclosure. Accordingly, the cleaning cartridge 1200 is of the same cartridge type (e.g., it is configured to fit securely within the reusable handle of the formulation delivery device, it has the same shape and dimensions and a plurality of outlet nozzles) as the formulation cartridges described herein.

[0129] The primary function of the cleaning cartridge 1200 is to fluidly connect to a formulation delivery device, and provide a cleaning liquid 1202 (e.g., water) that is flushed through a formulation dispensing assembly as part of a cleaning routine. Accordingly, the cleaning cartridge 1200 is a reusable assembly with a body portion 1204 formed of an ABS plastic or other suitable rigid polymer. The body portion 1204 supports a cleaning liquid reservoir 1206, i.e., a tank, that stores the cleaning liquid 1202 therein, e.g., 50 to 200 mL thereof. The cleaning liquid reservoir 1206 has a plurality of outlet nozzles 1208 that are sized and positioned to fluidly couple to the fluid conduits of the formulation delivery device.A 1210 refill cap makes it easy to refill the 1206 cleaning fluid reservoir.
