One or more methods or techniques are described that enable a user to apply a treatment formulation to human hair and scalp tissue. The following description generally provides representative examples relating to hair and scalp treatment delivery systems, devices, and formulation cartridges therefor. In one embodiment, it is beneficial for the treatment formulation to be applied to targeted areas of hair or scalp tissue. In one embodiment, for example, when applying a colored dye to the hair roots during a color maintenance treatment, it is desirable to apply the treatment formulation to a portion of the hair near the scalp. In another example, certain techniques involve applying a scalp treatment formulation directly to scalp tissue while minimizing contact with hair.

Existing systems for applying hair and scalp treatment formulations have been widely used. In one example, hair coloring kits are commonly used to change the appearance of hair color or to match gray hair, among other uses. Existing hair coloring systems have several disadvantages, including being difficult to use, time consuming, uneven coverage, unpredictable results, and heavy staining. In one aspect, existing hair coloring systems can be inefficient at blending and coloring the hair roots after a new section of hair grows from the scalp, where the natural hair color is the residual color of the dyed hair. It is different from the department. The present disclosure is directed to solving these and other needs.

In some embodiments, the hair coloring formulation includes at least one dye and a separate developer, which are mixed in controlled proportions. However, "formulation" is not limited to dyes and developers in this disclosure. The term "formulation" as used herein generally refers to any of a dye, developer, formulation, fluid, or any mixture thereof. In this disclosure, "formulations" include permanent hair dyes, semi-permanent hair dyes, color developers, conditioners, hair growth treatments such as minoxidil manufactured under the trade name ROGAINE®, hair protein treatments, disulfide bonds, etc. Includes repair hair treatments, fluid hair treatments, fluid scalp treatments, etc.

Embodiments of the present disclosure are configured to apply the formulation to targeted areas of hair and scalp tissue. While any of the formulations described above may be suitably applied using the embodiments described herein, the present disclosure is generally described as an example of a treatment formulation applied by the systems and devices described below. Refers to hair coloring preparations. However, it should be appreciated that any of the systems, devices, cartridges, and methods may be utilized with any of the formulations described above.

Cartridges of the common formulation cartridge type are generally configured to be inserted into cartridge cavities of a reusable handle of the formulation delivery device. For example, in some embodiments, the formulation cartridge and the cleaning cartridge have a common cross-sectional shape and dimensions. Additionally, some embodiments of the common formulation cartridge type have a common number and arrangement of output nozzles.

A common formulation cartridge 110 type thus allows a customer to utilize many different formulations in a single formulation delivery device 104. Exemplary formulation cartridge 110 types are described below in Figures 8A-10, and an exemplary cleaning cartridge 112 is described in Figure 12.

In some embodiments of the formulation delivery system 100, the elongated outer housing has different configurations between the formulation containing formulation cartridge 110 and the cleaning cartridge 112, but has a common shape and dimensions. For example, in some embodiments, the formulation cartridge 110 containing the formulation has the configuration of the partially reusable embodiment shown in FIGS. 8A-10, and the cleaning cartridge 112 has a similar have a shape and dimensions, but different materials and components.

Another feature of the formulation cartridge 110 type is a number of liquid output nozzles, which are of the same size and are arranged at the distal (forward) end of the formulation cartridge 110 in a configuration that fluidly connects with a corresponding number of liquid inlets (e.g., the first formulation inlets). In some embodiments, the liquid output nozzles are valves of a formulation packet disposed in the formulation cartridge 110.

Exemplary formulation cartridge 110 types configured for insertion into the formulation delivery device 104 and for storing a first formulation and a second formulation are described below in Figures 8A-10.

A wash cartridge 112 that is of a common formulation cartridge 110 type (i.e., has common external dimensions and a plurality of liquid output nozzles) allows a user to transfer a wash liquid (e.g., The formulation delivery device 104 may be cleaned by performing a cleaning routine that flushes the formulation delivery device 104 (water), thereby flushing the formulation delivery device 104 of any residual formulation. Advantageously, the wash cartridge 112 and wash routine allow a significant portion of the formulation delivery device 104 to be reused for different formulations, thereby reducing waste and cost.

The cleaning cartridge 112 includes a refillable cleaning fluid reservoir disposed within an outer housing that is fluidly connected to a plurality of output nozzles. Accordingly, a user can fill the cleaning fluid reservoir with a cleaning fluid, such as water, perform several cleaning routines on the formulation delivery device 104, and refill the cleaning fluid reservoir.

The formulation delivery device 104 is a connected electromechanical appliance that interacts with the user, the formulation cartridge 110, and possibly the application 106 to provide a customized and personalized user experience. Representative formulation delivery devices and their subsystems are described below with respect to FIGS. 4-7.

Generally, the formulation delivery device 104 includes a reusable handle configured to accept a formulation cartridge 110 type, and a formulation dispensing assembly and controller that are both disposed on the reusable handle. The formulation dispensing assembly includes at least one fluid conduit fluidly connected to the electric pump and to the reciprocating nozzle assembly for drawing formulation or cleaning fluid from the formulation cartridge 110 and dispensing the formulation or cleaning fluid through the reciprocating nozzle assembly. It is configured to dispense the cleaning liquid to the hair, scalp, or body parts of the user.

The controller is configured to switch between at least a cleaning routine and a formulation routine in response to one or more inputs indicating a cleaning cartridge or a formulation cartridge inserted into the reusable handle. The controller uses an encryption chip disposed on the formulation cartridge 110 to authenticate which formulations 108 are stored in the formulation cartridge 110 inserted into the reusable handle at a given time. Communicate with the cartridge authentication interface's encrypted chip reader inside the reusable handle to read the . 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 wash cartridge 112, the controller causes the formulation delivery device 104 to perform a formulation routine that dispenses the authenticated formulation from the formulation cartridge and through the formulation dispensing assembly. Based on the authorized cleaning cartridge 112, the controller causes the formulation delivery device 104 to perform a cleaning routine that dispenses cleaning fluid through the formulation dispensing assembly.

Application 106 includes logic configured to operate on a non-transitory machine-readable storage medium and includes modules to personalize the user experience, provide useful analytics, and enable electronic commerce. Application 106 operates on a mobile device 114, such as a smartphone, tablet, etc., to provide readily actionable information to a user (e.g., an end user or a salon technician) through multiple modules described below with respect to FIG. have a dialogue with In some embodiments, application 106 communicates with formulation delivery device 104 and a network 116, such as a mobile network, a cloud-based enterprise network, a local area network, etc.

Together, the formulation product line 102, formulation delivery device 104, and application 106 provide an improved and customized user experience. Each of the above elements of formulation delivery system 100 will now be described in detail.

In one embodiment, formulation dispensing assembly 214 includes a first fluid conduit fluidly connected to a first formulation inlet (which couples with a first liquid output nozzle of formulation cartridge 110); a second fluid conduit fluidly connected to a second formulation inlet (coupling with a second liquid output nozzle of formulation cartridge 110), a motor 218, and a pump 220 driven by motor 218; and a reciprocating nozzle assembly 222 also driven by motor 218.

Cartridge authentication interface 210 is an RFID reader, near-field reader, etc. disposed on reusable handle 202, and when formulation cartridge 110 is inserted therein, cartridge authentication interface 210 is configured to operate as described below. An encryption chip disposed on the formulation cartridge 224 is read to authenticate the formulation cartridge in connection with the formulation routine module 226 that performs the formulation.

Optional position sensor 216 includes one or more sensors that individually or collectively assist in determining the position and orientation of 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 (eg, capacitive touch sensors), proximity sensors (eg, optical proximity sensors), and the like. The signals transmitted from the position sensor 216 are used by the controller 204, and several modules thereof, to increase the accuracy and efficiency of formulation application to the user's hair or scalp.

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

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

Data store 208 is a tangible machine-readable storage medium that includes a mechanism for storing information in a non-transitory form that is accessible by a machine (eg, processor 206 or mobile device 114). For example, machine-readable storage media include recordable/non-recordable media (eg, read-only memory (ROM), random access memory (RAM), magnetic disk storage media, optical storage media, flash memory devices, etc.).

The modules described below are representative and not limiting. Accordingly, some embodiments of controller 204 include additional modules, while other embodiments include fewer than all modules.

The cartridge authentication module 230 communicates with the cartridge authentication interface 210 to authenticate any formulation cartridge 224 or cleaning cartridge 228 inserted into the reusable handle 202. For example, when the formulation cartridge 224 is inserted 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, the cartridge authentication module 230 "unlocks" the formulation delivery device 200, e.g., the formulation routine module 226. However, if the cartridge authentication interface 210 is unable to successfully authenticate the formulation cartridge inserted into the reusable handle 202, the cartridge authentication module 230 does not unlock the formulation delivery device 200. For example, if the formulation cartridge is a counterfeit cartridge or another cartridge containing an adulterated formulation, the cartridge authentication module 230 does not unlock the functionality of the formulation delivery device 200. In this way, the cartridge authentication module 230 advantageously prevents users from being harmed or having a poor experience.

Cartridge authentication module 230 is configured to read additional information from the encrypted chip, including one or more of formulation identification information, starting formulation quantity, formulation expiration date, and formulation manufacturing date, in some embodiments. It is composed of In such embodiments, cartridge authentication module 230 sends additional information to other modules for later use.

Execute the above blending routine. A compounding routine dispenses the authenticated formulation 108 from the formulation cartridge 224 through the reciprocating nozzle assembly 222 . For example, the hair care dispensing routine may dispense one or more hair care formulations from the reciprocating nozzle assembly 222 for a particular dispensing time, at a particular liquid flow rate of the pump, at a nozzle reciprocation frequency, and/or at a reciprocating motion of the reciprocating nozzle assembly 222. Dispensing in amplitude and/or other device operating parameters specified by a formulation routine stored in formulation routine module 226. In this way, the formulation delivery device 200 can be based on the specific formulation stored in the authenticated formulation cartridge 224 inserted into the formulation delivery device for more effective hair and scalp treatment. and adjust one or more device operating parameters.

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

The wash routine module 232 stores wash routines and dispenses formulations after the wash cartridge 228 (having a reservoir filled with wash fluid) is inserted into the reusable handle 202 and authenticated by the cartridge authentication module 230. 2. Cause assembly 214 to perform a cleaning routine. The cleaning routine includes applying cleaning fluid from an authorized cleaning cartridge 228 through the reciprocating nozzle assembly 222 (e.g., at a predetermined flow rate for a predetermined period of time) to evacuate residual formulation within the formulation dispensing assembly 214. distribute. The cleaning routine is effective, for example, after one formulation is utilized with the formulation delivery device 200, but before a second, different formulation is utilized. In some embodiments, the cleaning routine operates pump 220 at a higher flow rate than one or more (or all) formulation routines stored by formulation routine module 226 to remove any residual formulation.

In some embodiments, controller 204 executes at least a wash routine (provided by wash routine module 232) in response to one or more inputs indicating a wash cartridge or formulation cartridge inserted into the reusable handle. and a compounding routine (provided by compounding routine module 226). Typical inputs include formulation cartridge or wash cartridge authentication provided by cartridge authentication module 230.

According to the methods of the present disclosure, a method of cleaning any of the formulation delivery devices includes the steps of: inserting a cleaning cartridge at least partially filled with cleaning liquid into a reusable handle of the formulation delivery device; and performing a cleaning routine until the cleaning fluid dispensed through the material dispensing assembly is clean.

Power management module 234 provides power from power supply 212 to one or more of controller 204 , cartridge authentication interface 210 , formulation dispensing assembly 214 , and position sensor 216 . In addition, the power management module 234 conserves available power sources (e.g., conserves battery life) by switching the formulation delivery device 104 between a sleep state (passive state) and an awake state (active state). (preserve).

Sleep/Awake module 236 manages whether formulation delivery device 200 is awake or asleep. Formulation delivery device 200 is in a sleep state by default, thereby providing little power from power supply 212 to formulation dispensing assembly 214, cartridge authentication interface 210, and/or controller 204. In the sleep state, formulation delivery device 200 is unable to perform brewing or cleaning routines. In the awake state, by comparison, the controller 204, cartridge authentication interface 210, formulation dispensing assembly 214, and position sensor 216 are sufficiently powered such that the formulation delivery device 104 can perform one or more brewing or cleaning routines. Supplied. In some embodiments, the formulation delivery device 104 is delivered by pushing a button disposed on the reusable handle 202 or by inserting the formulation cartridge 224 or wash cartridge 228 into the reusable handle 202. By doing so, the device is "waked up," or brought out of sleep, into an awake state. In some embodiments, formulation delivery device 200 returns to sleep after a predetermined period of inactivity (eg, 120 seconds of inactivity).

Position module 238 utilizes the position signal provided by position sensor 216 to determine the position of formulation delivery device 200, which position information is then used to facilitate execution of a compounding routine, such as a calibration routine. , provided to the formulation routine module 226. In some embodiments, the position module 238 may be configured to perform a calibration routine (described below), for example, and/or to enable an application to display accurate application instructions based on the position signal. to provide a location signal (via a transceiver) to an application stored on the mobile device.

FIG. 3 shows a schematic diagram of an exemplary application 300 that has all the features of application 106 of FIG. 1 and includes all formulation delivery systems and formulation delivery devices of the present disclosure. Please be understood to be compatible with the following. As mentioned above, application 300 is configured to run on a device, for example a mobile device such as a smartphone or tablet. In one representative example, application 300 is described in the context of a mobile device 302 connected to a network 304, but this is not a limitation.

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 the exemplary formulation delivery device.

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 thereon. Thus, for each module, the user interface presented on display 306 is configured to both display information and receive user input.

Application 300 includes several modules that personalize the user experience, such as user profile module 312 and user routines module 314. The modules described below are representative and not limiting. Accordingly, some embodiments of application 300 include additional modules, while other embodiments include fewer than all modules.

The user profile module 312 builds one or more profiles for users of the formulation delivery device 104. These profiles are provided as inputs to other modules, such as the user routines module 314 and the e-commerce module 316. Thus, the 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), dyed/undyed condition, 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.

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 the 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 for the user and/or to select one or more tutorials to present on the display 306.

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

The user routine module 314, in some embodiments, helps users to effectively utilize the connected formulation delivery device by developing one or more user-specific routines for each user based on one or more user profile inputs. That is, the user routine module 314 builds a new formulation routine (rather than selecting a pre-defined formulation routine) to effectively handle one or more conditions or achieve one or more goals identified by the user profile inputs. As one representative example, if the user input indicates that the user's hair is both colored and damaged, the user routine module 314 builds a user-specific routine that selects an appropriate hair repair formulation and shampoo formulation for the user's hair color from a formulation product line, and displays (e.g., as instructions) the user-specific routine for utilizing the selected hair repair formulation and shampoo at determined intervals to improve the health of the user's hair.

In one example, the user routines module 314 receives a position signal from a position sensor indicating that the formulation delivery device is positioned on the left side of the user's head, and based on the received position signal, the user routines module 314 displays a video instructing the user to apply the scalp treatment formulation by moving the formulation delivery device from the left side of the head to the right side of the head while dispensing the scalp treatment formulation.

In some embodiments, the user routine module 314 receives a position signal from the formulation delivery device and displays precise application instructions based on the position signal.

Calibration module 318 assists the user in calibrating the formulation delivery device, which improves the effectiveness of compounding routines performed by the formulation delivery device. In some embodiments, the calibration module 318 displays a passive tutorial (eg, a pre-recorded instructional video) that instructs the user how to complete the calibration routine. In some embodiments, the calibration module 318 provides instructions on how to use the completed calibration routine when a user uses the formulation delivery device and when the calibration module 318 receives a position signal from the formulation delivery device. provides one or more active instruction sets to

According to one exemplary calibration routine, the calibration module 318 instructs the user to place the formulation delivery device at multiple calibration locations on the user's body part, for example, in a specific order (e.g., left head, then right head, then front hairline, then back hairline). The user then moves the formulation delivery device to each of the calibration locations, and the user presses a button or other action on the formulation delivery device when the formulation delivery device is in the designated calibration location and/or as the user moves the formulation delivery device from one calibration location to another.

Based on the position signal received from the formulation delivery device's position sensor, the calibration module 318 and/or the formulation delivery device records a calibration location. Calibration module 318 and/or formulation delivery device then adjusts one or more user-specific routines based on the recorded calibration locations. In some embodiments, this adjusting step includes adjusting the spatial limits and/or duration of one or more formulation routines stored in the formulation routine module.

Manual adjustment module 320 allows a user to adjust one or more device operating parameters (e.g., flow rate, dispensing time, round trip) of a formulation delivery device for the benefit of greater control over the formulation delivery device and a more customized user experience. allows manual adjustment of the dynamic amplitude, or reciprocating frequency). Accordingly, manual adjustment module 320 includes a user interface having one or more user-adjustable and virtual sliding scales, switches, editable value fields, etc. configured to receive one or more operating parameter inputs from a user. present. Manual adjustment module 320 receives operating parameter inputs and transmits the operating parameter inputs to a formulation delivery device (e.g., a formulation routine module), so that the formulation delivery device adjusts the operating parameter inputs based on the corresponding operating parameter inputs (e.g., (to match the operating parameter input), adjust the corresponding device operating parameters.

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

Formula creation module 324 allows a user to create a custom formulation based on the user's selection of one or more formulation inputs, where the one or more formulation inputs produce one or more desired results (e.g. , desired hair color), one or more formulation inputs (eg, an indication that the user's hair is damaged), and/or a user profile input provided to user profile module 312 . Accordingly, recipe creation module 324 is configured to receive one or more user profile inputs from user profile module 312 and to formulate a custom formulation based on those inputs.

A formulation dispensing assembly 410 dispenses a formulation or cleaning fluid from a formulation cartridge 402 and includes a pump, a fluid conduit, a mixing chamber, and a plurality of optional standoff portions 416 in front of a reusable handle 406 . and a reciprocating nozzle assembly 414 (described below) with a nozzle extending away from the end. Reciprocating nozzle assembly 414 includes a plurality of annular nozzles that reciprocate back and forth along the track of reusable handle 406 while dispensing the formulation onto the user's skin or hair. In some embodiments, the reciprocating nozzle assembly 414 has a reciprocating amplitude of 7.0 mm to 12.0 mm (e.g., 8.0 mm to 11.0 mm, or 9.0 mm to 10.0 mm), and/or It reciprocates at a dynamic frequency of 5.0 Hz to 10.0 Hz (for example, 6.0 Hz to 9.0 Hz, 6.0 Hz to 8.0 Hz), and these are the formulation routine module, cleaning routine module, user routine module, manual adjustment module, or adjustable by other modules.

As shown in FIG. 5, the formulation cartridge 402 has one or more formulation packets 418 disposed therein, each of which is inserted into the cartridge cavity 424 until the formulation cartridge 402 is fully inserted into the cartridge cavity 424. The formulation cartridge 402 then has an output nozzle 420 projecting from the distal (front) end of the formulation cartridge 402 in a configuration that fluidly connects with a corresponding formulation inlet 422 of the formulation dispensing assembly 410 .

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 button 426 activates any of the features of the module described above in FIG. 2. For example, in some embodiments, pressing button 426 activates a sleep/wake module stored in controller 412, thereby waking formulation delivery device 400 from a sleep state to an awake state. In some embodiments, pressing button 426 while a formulation cartridge is inserted into reusable handle 406 activates a compounding routine module stored in controller 412, thereby starting a compounding routine.

In some embodiments, pressing button 426 while the wash cartridge is inserted into reusable handle 406 activates a wash routine module stored in controller 412, thereby starting a wash routine. A visual indicator 428 (e.g., an LED) disposed along the reusable handle 406 indicates the amount of formulation remaining and the remaining battery life based on, for example, the dispensing time determined by the formulation routine module of the controller. Indicates one or more of the following. Some embodiments include additional buttons and/or different numbers of visual indicators 428 with different functions, and the illustrated embodiment is not limiting. In some embodiments, visual indicator 428 is a multi-segment LED, with each segment corresponding to an equal percentage of the formulation remaining in the formulation cartridge.

The controller 412 includes logic (stored in its data store) that, when executed by the processor of the controller 412 , generates a combination within the reusable handle 406 to authenticate the formulation cartridge 402 . A disposed cartridge authentication interface 430 (eg, an RFID reader) reads the encryption chip 432 on the formulation cartridge 402. Encrypted chip 432 stores at least one of the following: formulation cartridge 402, formulation identification information, starting formulation quantity, formulation expiration date, and formulation manufacturing date.

The controller 412 also, when executed, causes the formulation delivery device to dispense the first formulation and the second formulation from the formulation cartridge 402 through the formulation dispensing assembly based on authenticating the formulation cartridge 402. ) includes logic for executing a compounding routine that dispenses the mixed formulation. For example, the formulation delivery device authenticates the first and second formulations after (or at the time of) inserting the formulation cartridge into the reusable handle and then presses a button on the reusable handle. In response to pressing, the formulation dispensing assembly 410 causes the first and second formulations to be continuously or intermittently mixed and dispensed from the reciprocating nozzle assembly to a predetermined amount as long as the button is pressed on formulation dispensing assembly 410 executing a formulation routine that dispenses at one or more of the following device operating parameters: formulation flow rate, reciprocation frequency, and reciprocation amplitude;

In some embodiments, the controller 412, when executed, also causes the formulation delivery device to dispense cleaning fluid through the formulation dispensing assembly based on authenticating the cleaning cartridge inserted into the reusable handle. Contains logic that causes the cleaning routine to execute. For example, the formulation delivery device authenticates a wash cartridge inserted into the reusable handle and then, in response to pressing a button on the reusable handle, causes the formulation dispensing assembly 410 to press the button. As long as the button is pressed, the reciprocating nozzle assembly continuously or intermittently delivers cleaning fluid (e.g., water) at one or more of the following predetermined device operating parameters: cleaning fluid flow rate, reciprocation frequency, and reciprocation amplitude. Perform a cleaning routine that dispenses In some embodiments, the flow rate of the cleaning fluid is greater than the flow rate of one or more formulations of the formulation routines stored in the controller 412 for the benefit of effectively flushing residual formulations from the formulation dispensing assembly. .

The pull adapter 404 attaches to a reusable handle 406 above the reciprocating nozzle assembly 414. In some embodiments, the pull adapter 404 provides an audible feedback signal when properly engaged with the reusable handle 406.

6 and 7 show an exemplary formulation dispensing assembly 600 that 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 the formulation cartridge to the skin or hair of a user. In some embodiments, the formulation dispensing assembly 600 dispenses the mixed formulation at a flow rate of 20 mL/min to 40 mL/min or 120 mL per 4 minutes, e.g., 20 mL/min to 35 mL/min, 20 mL/min to 30 mL/min, 20 mL/min to 25 mL/min, 25 mL/min to 35 mL/min, 25 mL/min to 30 mL/min, or 35 mL/min to 40 mL/min.

The formulation dispensing assembly 600 is fluidly connected to a first formulation inlet 602 and a second formulation inlet 604, respectively. a first fluid conduit 606 and a second fluid conduit 608. In some embodiments, each of the first formulation inlet 602 and the second formulation inlet 604 is connected aft (i.e., reusable) from the first fluid conduit and the second fluid conduit, respectively. When disposed on the handle, the protrusion is formed as a protrusion extending toward the rear end of the reusable handle (towards the cartridge cavity), the protrusion being configured to protrude into the formulation cartridge.

Formulation dispensing assembly 600 also includes a motor 610, a gearbox 612 operably connected to motor 610, and a pump 614 driven by motor 610 via gearbox 612. In some embodiments, pump 614 is a peristaltic pump that has been found to improve formulation distribution when utilized in combination with the mixing chamber and tapered formulation channels described herein. .

Reciprocating nozzle assembly 616 includes a plurality of annular nozzles 618 disposed on a comb 620 that, in use, combs the user's skin to achieve more uniform formulation coverage. or circulate back and forth along the track of the reusable handle 406 dispensing the formulation onto the hair. Each nozzle 618 includes a formulation channel 622 therethrough, each of which is fluidly connected to first fluid conduit 606 and second fluid conduit 608 via manifold 624 . In some embodiments, each formulation channel 622 is tapered for the benefit of increasing formulation dispensing speed and/or to further mix the two formulations. Tapered formulation channels may be utilized in combination with other features described herein, for example, pump 614 is a peristaltic pump and/or turbulent mixing chamber includes one or more helical mixers 626. It turned out to be advantageous.

The motor 610 and gearbox 612 drive the reciprocating nozzle assembly 616 in a linear reciprocating motion. In one embodiment, the linear reciprocating motion is induced by an eccentric roller 628 coupled to an output shaft 630 of the gearbox 612, which rotates within an annular bracket of the comb 620. Driving the pump 614 and the reciprocating nozzle assembly 616 from a common motor 610 improves power efficiency and reduces weight and size, thereby improving the form factor of the formulation delivery device. Nevertheless, some embodiments use two or more motors to drive the pump 614 and the reciprocating nozzle assembly 616.

The nozzle 618 is fluidly connected to the first fluid conduit 606 and the second fluid conduit 608 via a turbulent mixing chamber 632, which turbulent mixing chamber 632 is configured to create a mixed formulation. A first formulation drawn from the formulation cartridge via first fluid conduit 606 is mixed with a second formulation drawn from the formulation cartridge via second fluid conduit 608. In particular, the turbulent mixing chamber 632 includes one or more mixing elements that combine two formulations under pressure in a common chamber and create a turbulent flow (as distinguished from laminar flow) of the mixed formulation. The two formulations are mixed by flowing the two formulations past each other. The proportion of the first formulation to the second formulation varies in various embodiments. For example, in some embodiments, the mixed formulation comprises a ratio of about 0.8:1.0 to 1.2:1.0, eg, 0.85, 0.90, 0.95, 1. 00, 1.05, 1.10, or 1.15 of the first formulation and the second formulation.

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

In some embodiments, turbulent mixing chamber 632 includes a helical mixer 626 disposed therein. Some embodiments include multiple helical mixers 626 fluidly connected in series along a fluid path within the turbulent mixing chamber 632 to improve mixing. In some embodiments, each helical mixer has an outer diameter of between 2.00 mm and 5.00 mm, such as between 3.0 mm and 4.00 mm, such as 3.18 mm. In some embodiments, each helical mixer has an overall length of between 20.0 mm and 40.0 mm, such as between 25.0 mm and 35.0 mm, such as 33.0 mm. In some embodiments, each helical mixer has a length-to-diameter pitch of between 0.75 and 1.25, such as between 0.80 and 0.90, e.g. /[outer diameter x number of mixing elements]). The combination of the above specifications provides the best homogeneity of the mixed formulation, especially when the two formulations are not mixed until downstream of pump 614, slightly upstream of reciprocating nozzle assembly 616, and when pump 614 is a peristaltic pump. It was discovered that it produces sex.

In use, pump 614 pumps a formulation from the connected formulation cartridge through first fluid conduit 606 and second fluid conduit 608, through turbulent mixing chamber 632, through manifold 624, and through nozzle 618. Pull in. In the illustrated embodiment, first fluid conduit 606 and second fluid conduit 608 are maintained fluidly separate downstream of pump 614 to prevent mixing of the two formulations up to turbulent mixing chamber 632. . As previously discussed, the two formulations are mixed just prior to dispensing (ie, between pump 614 and manifold 624) to improve the homogeneity of the mixed formulation.

8A-10 illustrate a representative formulation cartridge 800 of the formulation cartridge type 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 do not require the use of the sustainable formulation cartridge 800 shown in FIGS. 8A-10.

The formulation cartridge 800 is a sustainable embodiment specifically designed to reduce waste and environmental impact while providing a user-friendly experience. To that end, formulation cartridge 800 includes two major components: a handle portion 802 and a disposable refill packet 804 configured to reversibly slide within handle portion 802 . Historically, known cartridges were designed to be discarded in their entirety after the formulation stored therein was used up, leading to significant waste and higher consumer prices.

In contrast to known cartridges, the formulation cartridge 800 is configured such that the handle portion 802 is indefinitely reusable, and only the disposable refill packets 804 need to be discarded or recycled after exhausting the formulation stored therein. Still further, each disposable refill packet 804 is configured to be broken down into smaller components, some of which are recyclable and others are discarded. Thus, the formulation cartridge 800 utilizes an innovative structure to reduce waste and improve user experience.

Handle portion 802 is sized, dimensioned, and configured for repeated insertion into a cartridge cavity of a formulation delivery device. Accordingly, the handle portion 802 is formed of ABS plastic or similar hard polymer or other material and extends away from the handle portion 802 with a hollow handle portion 802 configured to receive the disposable refill packet 804 therein. tray portion 806. The handle portion 802 is a two-piece assembly in the illustrated exemplary embodiment (although it may be a single piece in other embodiments) and is fully inserted into the cartridge cavity of the formulation delivery device. and is sized and dimensioned to form a seamless extension of the handle thereof. Tray portion 808 has a U-shape that projects away from handle portion 802 and is configured to support disposable refill packet 804 (eg, front body portion 810). To facilitate secure engagement and easy removal, handle portion 802 includes coupling means for coupling formulation cartridge 800 to a reusable handle of a formulation delivery device. Exemplary coupling means include a cartridge release 812 (eg, a latch) formed in handle portion 802 that engages the formulation delivery device upon proper and complete insertion.

The disposable refill packet 804 stores a first formulation packet 814 and a second formulation packet 816, each containing a first formulation 818 and a second formulation 820. Each of the first formulation packet 814 and the second formulation packet 816 has between 40 mL and 70 mL, such as 50 mL to 60 mL, or 55 mL. In some embodiments, first formulation packet 814 and second formulation packet 816 have different amounts.

The first formulation 818 and the second formulation 820 each include any of the formulations described herein, such as a permanent hair dye, a semi-permanent hair dye, a color developer, a conditioner, minoxidil, etc. hair growth treatment, hair protein treatment, disulfide bond repair hair treatment, fluid hair treatment, fluid scalp treatment, etc. In some embodiments, first formulation 818 and 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 color developer. In other embodiments, first formulation 818 and second formulation 820 are the same (eg, a conditioner or scalp treatment formulation).

As shown in FIG. 9, each formulation packet includes a formulation-containing packet 822 and, when the formulation cartridge 800 is received within the handheld formulation dispensing device, a disposable refill packet to the dispensing nozzle unit of the formulation delivery device. selectively-fluidic coupling valve means. Typical valve means include valve 824 through which the formulation exits packet 822. For representative formulation packets, see International Patent Application No. PCT/US2018/052345, filed September 24, 2018, assigned to L'Oreal SA, and International Patent Application No. PCT/US2018/052345, filed September 24, 2018, and assigned to L'Oreal SA, and No. 17/133,110, assigned to Oreal SA, both of which are incorporated herein by reference in their entirety for all purposes.

The disposable refill packet 804 also includes a disposable elongate body portion 826 that provides structure to the disposable refill packet 804 and includes a first formulation packet 814 and a second formulation packet 816. In some embodiments, the body portion 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 between 25 mm and 50 mm (e.g., 30 mm to 45 mm). 35 mm to 40 mm, or 36 mm). Body portion 826 has a rear body portion 828 and a narrow front body portion 810 . The rear body portion 828 has a larger cross-sectional dimension than the front body portion 810 and remains within the handle portion 802 of the handle portion 802 (eg, by a friction fit) during use. A narrow front body portion 810 is supported by the tray portion 806 of the handle portion 802 and projects into the cartridge cavity of the formulation delivery device during use.

In the illustrated embodiment, body portion 826 is constructed from a recyclable material, such as structured paper (eg, cardboard). In some embodiments where the body portion 826 is formed of paper, the paper is 8-12 points (e.g., 8.5 points, 9 points) to provide sufficient stiffness without introducing excessive disposable material. .0 points, 9.5 points, 10.0 points, 10.5 points, 11.0 points, or 11.5 points). In some such embodiments, body portion 826 is formed of a single recyclable material. As an example, in the illustrated embodiment, body portion 826 is formed from a single piece of paper. As shown in FIG. 9, this folded configuration creates an eight-sided polygonal cross-section in the rear body portion 828 and a six-sided polygonal cross-section in the forward body portion 810. To facilitate assembly, some embodiments of body portion 826 include one or more indentations or guidelines to ensure accurate folding. The polygonal cross-section of the illustrated embodiment is representative and not limiting. Other embodiments have triangular, rectangular, pentagonal, hexagonal, heptagonal, octagonal, or other polygonal cross-sectional shapes. In other embodiments, body portion 826 has the shape and structure described herein, but is not constructed from recyclable materials.

Optional packet sleeve 830 provides several important advantages. First, packet sleeve 830 provides additional structure to disposable refill packet 804 by sliding over and reinforcing front body portion 810. Thus, in some embodiments, packet sleeve 830 has a greater weight or thickness compared to the material forming body portion 826, although this is not required. In some embodiments, packet sleeve 830 is also formed of a recyclable material, which may be the same recyclable material as body portion 826.

Second, the packet sleeve 830 couples with the valve frame 832. For example, the illustrated packet sleeve 830 includes a plurality of engagement member recesses 834 configured to reversibly couple with the engagement members of the valve frame 832.

Third, the packet sleeve 830 facilitates disassembly of the disposable refill packet 804. As shown in FIGS. 8A and 9, the packet sleeve 830 includes an optional integral tearaway 836 (e.g., perforation with a pull tab). During use, after the formulation is used up, the user pulls the pull tab of the integral tearaway 836, thereby separating the valve frame 832 from the packet sleeve 830. Once this action is completed, the packet sleeve 830 is recycled and the valve frame 832 is discarded. In some embodiments, the integral tearaway 836 is disposed on the body portion 826, e.g., the front body portion 810.

Although packet sleeve 830 provides several benefits, packet sleeve 830 is optional. In some embodiments, one or more of the above features of packet sleeve 830 are integrally formed with body portion 826.

The valve frame 832 includes an encryption chip adjacent to the cartridge authentication interface of the formulation delivery device for precise and secure coupling with the formulation delivery device (and in particular with its formulation dispensing assembly). 838 provides a rigid structure that supports the formulation packet valve 824 and the encryption chip 838. Thus, the valve frame 832 is formed from ABS plastic, HDPE, or other hard polymer, or other material. A plurality of valve engagement units 840 extend through the forward end of valve frame 832. Each valve engagement unit 840 receives and secures one of the formulation packet valves 824. In some embodiments, the valve engagement unit 840 is a valve opening disposed through one side of the valve frame 832, and the valve opening is sized to receive a valve of a formulation packet. To facilitate coupling with packet sleeve 830 (or body portion 826 in some embodiments), valve frame 832 includes an engagement member 842 (eg, a tab) extending therefrom.

Encryption chip 838 is disposed on disposable refill packet 804, for example, on body portion 826 or (as in the illustrated embodiment) on valve frame 832. Encryption chip 838 is placed on disposable refill packet 804 such that it is positioned to be read by the cartridge authentication interface of formulation cartridge 800 when it is inserted into the formulation delivery device. Accordingly, the encryption chip 838 stores information about the formulation cartridge 800 and its contents, such as at least one of formulation identification information, starting formulation quantity, formulation expiration date, and formulation manufacturing date. .

In this manner, body portion 826, packet sleeve 830, formulation packet, and valve frame 832 form disposable refill packet 804. In use, the disposable refill packet 804 is reversibly connected to the handle portion 802 by means of securing means, such as a friction fit between the disposable refill packet 804 and the handle portion 802, and by coupling tabs 844 on the body portion 826 or packet sleeve 830. Can be combined with The coupling tab 844 engages the handle portion 802 when the disposable refill packet 804 is inserted therein, and retains the disposable refill packet 804 therein until it is forcibly pulled from the handle portion 802. To further aid in retaining the disposable refill packet 804 within the handle portion 802, the illustrated handle portion 802 includes one or more optional retention elements 846 (in this embodiment, a flexure that engages the disposable refill packet 804). possible tabs).

FIG. 11 illustrates an exemplary method 1100 of the present disclosure, shown in FIG. 11, that may be used with any of the formulation cartridges of the present disclosure, such as formulation cartridge 800 of FIGS. 8A-10.

At block 1102, a depleted formulation cartridge is provided, ie, a formulation packet in which the formulation packets have run out of formulation. In some embodiments, the formulation cartridge is removed from the formulation delivery device, for example, by pressing on the cartridge release and pulling the formulation cartridge out of the formulation delivery device.

At block 1104, the disposable refill packet is separated from the reusable cartridge body, for example, by pulling the disposable refill packet away from the reusable cartridge body with sufficient force to overcome the retention force exerted by the mating tabs and retention elements.

At optional block 1106, the recyclable portion of the disposable replenishment packet is separated from the non-recyclable portion of the disposable replenishment packet. For example, the valve frame and formulation packet can be removed by, for example, peeling off the integral tear-off section on the packet sleeve or body portion and pulling the valve frame (along with the spent formulation packet secured thereto) to remove the packet sleeve and body. The separation from the body portion and/or the optional packet sleeve (both of which are recyclable in some embodiments) is separated from the body portion and/or the optional packet sleeve.

In optional block 1108, the recyclable portions of the disposable refill packet are recycled (i.e., the body portion and/or packet sleeve) and the non-recyclable portions are discarded (i.e., the exhausted formulation packet and valve frame).

At block 1110, a new disposable refill packet is inserted into the reusable cartridge body.

In block 1112, the reloaded formulation cartridge is reinserted into the formulation delivery device after inserting a new disposable refill packet into the reusable cartridge body.

Accordingly, the present disclosure provides not only a sustainable formulation cartridge, but also methods of using it to further reduce waste and environmental impact.

FIG. 12 shows an exemplary cleaning cartridge 1200 that has the same features as the cleaning cartridges previously described and is compatible with any formulation delivery system, formulation delivery device, and product line of the present disclosure. Thus, the cleaning cartridge 1200 is of the same cartridge type as the formulation cartridges described herein (e.g., configured to fit securely inside a reusable handle of a formulation delivery device, with the same shape and dimensions, as well as having multiple output nozzles).

The primary function of the cleaning cartridge 1200 is to fluidly connect with a formulation delivery device and provide a cleaning fluid 1202 (e.g., water) that is flowed through the formulation dispensing assembly as part of a cleaning routine. Thus, the cleaning cartridge 1200 is a reusable assembly having a body portion 1204 formed of ABS plastic or other suitably rigid polymer. The body portion 1204 supports a cleaning fluid reservoir 1206, or tank, that stores the cleaning fluid 1202 therein, for example, 50 mL to 200 mL thereof. The cleaning fluid reservoir 1206 has a number of output nozzles 1208 sized and positioned to fluidly couple with the fluid conduits of the formulation delivery device. A refill cap 1210 facilitates refilling of the cleaning fluid reservoir 1206.
