[0043] The foregoing aspects and many of the attendant advantages of this disclosure will become more readily appreciated as the same become better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings.DETAILED DESCRIPTION

[0044] The present disclosure provides new and useful hair clamp adapters and hair coloring adapters devices, systems, and methods.

[0045] At least some hair formulations can be relatively thick or viscous, and difficult to apply to the hair in correct amounts. This leads to underapplication of the haircare formulation due to difficulty applying the composition and overapplication due to difficulty removing excess composition. Using approaches as disclosed herein, haircare fluid formulation systems and devices, such as the Colorsonic™ device as commercially provided by L’Oreal as a non-limiting example, can be advantageously configured for accurate and precise application of haircare formulas, including viscous formulations, for hair cleaning and treatments, without underapplication or overapplication of the compositions. The disclosed approaches are able to controllably contact and compress the hair, and deliver steady amounts of fluid formulations to the hair through the use of a hair clamp adapter that includes one or more compressible materials, such as one or more sponges, that transmit the formula therethrough to clamped strands of the hair and enable the user to apply the composition to the hair and wipe away excess composition with edge portions of the one or more sponges, as part of a scraping movement. The disclosed approaches also enhance formulation delivery systems for even distribution of the composition across multiple strands of hair, enabling consistent results.

[0046] The present disclosure also relates to hair coloring adapters and methods for dying alternating hair strands using the same. Hair coloring has been an important aspect of the cosmetic arts for thousands of years, with historical evidence of hair coloration via natural dyes as far back as ancient Egypt and Rome. Despite this history, the process of coloring hair is well known to be messy and will frequently result in staining and damage to clothing, towels, furnishings, and the like.

[0047] Existing systems for the application of hair and scalp treatment formulations have been widely used. In one example, hair-coloring kits are generally used to change the appearance of the hair color or to blend gray hairs, among other uses. Many at-home hair coloring systems have several disadvantages, including difficulty of use, time consumption, uneven coverage, unpredictable results, and excessive mess.

[0048] While there have been advances in at-home hair coloring for the entire head of hair, there are still many challenges with creating textured and layered application patterns, such as is required to obtain hair highlighting or other non-uniform applicationsof hair dye to the head of hair. Traditionally, in such contexts, consumers visit a hair salon to have a hair coloring professional apply alternating layers of hair dye. This often involves manually separating strands of hair, brushing the hair onto sheets of foil, and an extensive waiting period.

[0049] Accordingly, there is a need for improved devices and methods that enable a subject to obtain a textured hair coloring style, either at home, at a hair salon, or at another suitable location, while minimizing the time of application and the mess that is created. The present disclosure addresses these and other long-felt and unmet needs in the art.

[0050] A formulation delivery system can be configured for compatible use with any of a plurality of formulation cartridges. By way of a non-limiting example, FIG. 1 shows a side perspective view of an example formulation delivery system, and FIG. 2 shows a rear perspective view of an example formulation cartridge. A formulation delivery system 100 can include a formulation cartridge 200. The shown formulation delivery system 100 is an example of a formulation delivery system as described in detail in U.S. Patent Application Publication No. US20240172858A1, published May 30, 2024, and assigned to L’Oreal, which is incorporated by reference herein in its entirety for all purposes. However, it is to be understood that aspects and embodiments of the present disclosure can be used with any formulation delivery system for hair coloring and / or hair bleaching, without departing from the scope and spirit of the disclosure.

[0051] The shown example formulation delivery system 100 includes a formulation product line 102, a formulation delivery device 104, and a formulation 106 (e.g., within a liquid reservoir 206 of a formulation cartridge 108, shown as a cutaway view within FIGs 1-2), which together enable application of a cosmetic composition to the hair of an individual for a personalized hair treatment experience, such as hair coloring and / or bleaching. Formulation product line 102 includes formulation cartridges 108, and formulation cartridges 108 can be of a same (or common) cartridge type configured for interchange and use with the formulation delivery device 104.

[0052] The formulation product line 102 can include a cosmetic composition as a hair bleaching formulation, which can include a bleach formula and a developer formula which, when mixed together by the formulation delivery device 104, form the cosmetic composition to be applied to the hair of an individual. In embodiments, a formulation product line 102 can comprise one or more cartridges that comprise: a bleach formula and a developer, a permanent hair dye and a developer, a semi-permanent hair dye and adeveloper, a shampoo, a conditioner, a hair growth treatment such as minoxidil, a hair protein treatment, a disulfide bond repairing hair treatment, a fluid scalp treatment, or the like.

[0053] In embodiments, a formulation product line 102 can include a cleaning cartridge comprising a cleaning solution therein for cleaning the formulation delivery device 104 before and / or after use. A cleaning solution can enable an individual to clean the formulation delivery device 104 by executing a cleaning routine, with the device and the cleaning solution cartridge, that flushes a cleaning liquid (e.g., water, saline) from the cleaning cartridge through fluid conduits of the formulation delivery device 104. This removes residual formulation from the formulation delivery device 104. Advantageously, the cleaning cartridge and cleaning routine enable a significant portion of the formulation delivery device 104 to be reused for different formulations, thereby reducing waste and cost. The cleaning cartridge can include a refillable cleaning liquid reservoir disposed inside the outer housing, which is fluidically connected to the plurality of output nozzles. Thus, a user can fill the cleaning liquid reservoir with a cleaning liquid such as water, execute a number of cleaning routines on the formulation delivery device 104, and refill the cleaning liquid reservoir.

[0054] The shown formulation cartridge 108 has an elongate shape and dimensions configured for insertion into a handle of the formulation delivery device 104, in particular into a cartridge cavity of the handle, for mixing and dispensing the cosmetic composition from the formulation delivery device 104. All or substantial portions of a formulation cartridge 108 can be comprised of one or more recyclable elements, for example, for managing the environmental impact of the system and product line.

[0055] The formulation cartridge 108 can comprise a plurality of liquid output nozzles, which are sized and positioned at a distal (forward) end of the formulation cartridge 108 in a configuration that fluidically connects with a corresponding plurality of liquid inlets (e.g., first formulation inlets) of the formulation delivery device 104. In embodiments, the liquid output nozzles are valves of formulation vessels (e.g., pouches or packets) disposed in formulation cartridge 108.

[0056] FIG. 2 shows a formulation cartridge 200 which is compatible with any of the formulation delivery systems, formulation delivery devices, and formulation product lines described herein. However, the formulation delivery systems, formulation deliverydevices, and formulation product lines described herein are not necessarily required to use the sustainable formulation cartridge 200 shown in FIG. 2.

[0057] In embodiments, the formulation cartridge 200 is sustainable and is designed to reduce waste and environmental impact, while delivering a user-friendly experience. It includes two main components: a handle portion 202 and a disposable formulation cartridge refill unit 212 (hereinafter referred to simply as refill unit 212) configured to reversibly slide into the handle portion 202. The formulation cartridge 200 is constructed such that the handle portion 202 can be reused indefinitely and the refill units 212 can be readily replaced after depletion of the formulation stored therein. Furthermore, refill unit 212 can be configured to be deconstructed into smaller components, at least some of which can be recycled in embodiments, and others disposed of. Thus, the formulation cartridge 200 utilizes an innovative structure to reduce waste and improve the user experience.

[0058] In embodiments, handle portion 202 is sized, dimensioned, and constructed to be repeatedly inserted into the cartridge cavity of the formulation delivery device. Accordingly, handle portion 202 can be formed of a plastic or similar rigid polymer or other material and includes a hollow handle portion 202 configured to receive the refill unit 212 therein. Refill unit 212 includes a refill packet comprising a shell enclosing at least one formulation vessel (e.g., a packet, pouch, or other vessel), for example a first formulation pouch and a second formulation pouch, and a valve frame coupled with the refill packet, e.g., a front body portion 210. In embodiments, at least one formulation vessel is a liquid reservoir 206. The first formulation pouch and second formulation pouch can contain a first formulation (e.g., bleach formula) and a second formulation (e.g., developer formula), respectively. The refill unit 212 can include a packet sleeve. In embodiments, a formulation vessel can comprise a formulation packet and an output nozzle.

[0059] In embodiments, the first formulation pouch and second formulation pouch, of the formulation cartridge 200, can each have 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 embodiments, first and second formulation pouches can have different volumes. In embodiments, refill unit 212 stores only one formulation vessel.

[0060] In embodiments, the first formulation and second formulation can be independently selected from any of the formulations described herein, or their equivalents in the art, and can include at least one non-fluid formulation, for example, a bleach formula, a permanent hair dye, a semi -permanent hair dye, a developer formula, a conditioner, a hair growth treatment such as minoxidil, a hair protein treatment, a disulfide bond repairing hair treatment, a fluid hair treatment, a fluid scalp treatment, and any combination thereof, or the like. In embodiments, the first formulation and second formulation differ. For example, in some embodiments, the first formulation is a bleach formula and the second formulation is a developer. In other embodiments, the first formulation and second formulation are the same (e.g., a conditioner or scalp treatment formulation).

[0061] In embodiments, formulation pouches include a formulation-containing packet and valve means comprising output nozzles 208 for selectively-fluidic coupling the refill unit to a dispensing nozzle unit of a formulation delivery device when the formulation cartridge 200 is received within the hand-held formulation dispensing device. Representative valve means include a valve through which the formulation exits the formulation-containing packet. Example formulation vessels are described in International Patent Application Publication No. WO2019067336A2, published Apr. 04, 2019, and assigned to L’Oreal S A, and U.S. Patent Application Publication No. US20210196021A1, published Jul. 01, 2021, and assigned to L’Oreal S A, both of which are hereby incorporated by reference in their entireties for all purposes.

[0062] In embodiments, the shell ( / .< ., outer portion) of the cartridge refill unit 212 has an elongate shape sized to be received within the reusable handle portion 202. The shell encloses and protects the first formulation pouch and second formulation pouch and engages the valve frame (described below). Thus, the shell functions as packaging which protects the formulation pouches during commerce prior to loading into the formulation delivery device.

[0063] In embodiments, the shell has a total length between 150 and 250 mm (e.g., 175-225 mm, 185-215 mm, 195-205 mm, or 200 mm) and a maximum cross-sectional dimension of 25-50 mm (e.g., 30-45 mm, 35-40 mm, or 36 mm). The shell has a rear body portion and a slender front body portion 210, e.g., a neck portion, extending away from the body portion. The body portion and the slender front body portion 210 generally align in a common longitudinal direction to enable assembly with the reusable handle portion 202, and to enable insertion into the cartridge cavity of the formulation delivery device. Inembodiments, the shell 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 embodiments, the shell is formed from a single piece of injection-molded paper material. In embodiments in which the shell is formed of paper, the paper has a weight between 8-12 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 impart sufficient stiffness without contributing excess disposable material.

[0064] In embodiments, the rear body portion of the shell has a larger cross- sectional dimension than the front body portion 210 when viewed in a plane normal to the longitudinal direction of the formulation cartridge 200. A hump or bulge imparts the larger cross-sectional area of the rear body portion relative to the slender front body portion 210. Advantageously, the hump or bulge enables the use of higher-volume formulation pouches. Additionally, the hump or bulge forms an abutment which abuts a corresponding interior face of the handle portion 202 and secures the longitudinal position of the shell during use, for example, by friction fit.

[0065] In embodiments, the slender front body portion 210 of the shell is sized to fit within the handle portion 202 and to project into the cartridge cavity of the formulation delivery device during use. The front body portion 210 couples with the valve frame. To facilitate secure connection and alignment with the valve frame, the front body portion 210 includes valve frame coupling means, for example at least one coupling tab configured to selectively engage the valve frame. In the illustrated embodiment, the front body portion 210 includes a single coupling tab extending away from a front end thereof. The coupling tab includes an engagement feature, for example a detent or raised prominence shaped and sized to engage a complementary aperture of the valve frame.

[0066] In embodiments, the shell can have any of various different configurations. For example, the shell can be a clamshell configuration formed with at least two partial shells (in this embodiment, first half 203 and second half 204) hingedly coupled. In embodiments, the shell includes a different number of partial shells, e.g., three or four partial shells which come together to enclose the formulation pouches. In still other embodiments, the shell comprises a single piece forming an open-ended tube into which the formulation pouches can be inserted. Alignment of the first half 203 and second half 204 enables correct attachment of the front body portion 210 to the valve frame.

[0067] While the illustrated shell is formed of an injection molded paper material, this construction is an example and is not limiting. In embodiments, the shell is formed of a single piece of die-cut paper stock, which is folded to impart a three-dimensional structure having the rear body portion and slender front body portion 210 extending away therefrom. In embodiments, this folded construction creates a polygonal cross section in the rear body portion and a polygonal cross section in the front body portion 210 (for example, octagonal and hexagonal cross sections, respectively). To facilitate assembly, embodiments of the shell include one or more scores or guidelines that ensure correct folding. Embodiments have a triangular, rectangular, pentagonal, hexagonal, heptagonal, octagonal, or other polygonal cross-sectional shape.

[0068] In embodiments, a packet sleeve can slide over the front body portion 210 and provide several important advantages. First, it imparts additional structure to the refill unit 212 by sliding over and reinforcing front body portion 210. Accordingly, in embodiments, packet sleeve has a greater weight or thickness as compared to the material that forms the shell; although this is not required. In embodiments, packet sleeve is formed of a recyclable material, which can be the same material as the shell. In embodiments, packet sleeve couples with the valve frame. For example, the packet sleeve can include a plurality of engagement member recesses configured to reversibly couple with engagement members of the valve frame. The packet sleeve can facilitate disassembly of the refill unit 212.

[0069] In embodiments, the valve frame provides a rigid structure which aligns the output nozzles 208 for correct fluid interconnection with the fluid conduits of the formulation delivery device. Accordingly, the valve frame can be formed from ABS plastic, HDPE, or another rigid polymer or other material. In embodiments, the valve frame is formed from a same material as the shell. Thus, the shell, formulation pouches, valve frame, and optional packet sleeve form the refill unit 212. In use, refill unit 212 is reversibly couplable with handle portion 202, e.g., by securing means such as coupling tabs on the shell or by friction fit between the refill unit 212 and the handle portion 202.

[0070] As shown by way of an example at FIG. 3A, a hair clamp adapter 300 is configured for attachment to and use with a formulation delivery device (e.g., 104 of FIG. 1) to controllably apply a cosmetic composition to hair of an individual. The hair clamp adapter 300 comprises a moving handle 301 slidingly attached to a moving arm 305 that comprises a first compressible substrate 306a thereon, and a stationary handle comprisinga stationary arm 302 that comprises a second compressible substrate 306b thereon. The moving arm 305 is hingedly attached to the stationary arm 302 via a hinge 305a and is slidingly attached to the stationary handle 302. As shown at FIG. 3B and FIG. 4, the stationary arm 302 and the second compressible substrate 306b each comprises a plurality of apertures (i.e., dotted lines of FIG. 3B, through which formulation pathways 307a, 307b, 307c, 307d are formed; see also formulation pathways 307a, 307b, 307c, and 307d of FIG. 4). The plurality of apertures of the stationary arm 302 are configured to align with a plurality of apertures of the second compressible substrate 306b to form a plurality of formulation pathways 307a, 307b, 307c, and 307d, for passage of the cosmetic composition therethrough. In the shown embodiment of FIGs 3A-3B, a bias of the hair clamp adapter 300, for example as formed by a spring 303, biases the hair clamp adapter 300 toward an unclamped configuration (z.e., as shown at FIG. 3B); as the bias is overcome as a result of a squeezing force applied to the moving handle 301 and / or the stationary handle 302, as occurs as a user grips the moving handle 301 and the stationary handle 302, the hair clamp adapter 300 transitions toward a clamped configuration (z.e., such that the compressible substrates 306a, 306b contact each other and the moving handle 301 contacts the stationary handle 302). In the clamped configuration, which can visually correspond to a pair of scissors in a closed configuration, a formulation dribble 308 contacts the compressible substrate 306a (z.e., on the moving arm 305), to transfer the cosmetic composition from the compressible substrate 306b of the stationary arm 302 to the compressible substrate 306a of the moving arm 305. In this manner, the cosmetic composition is consistently and evenly distributed along the compressible substrates 306a, 306b, forming a lather to be evenly applied to the hair during a hair treatment.

[0071] In embodiments, compressible substrates 306a, 306b can be comprised of naturally-occurring materials, such as sea sponges, or can be comprised of artificial or manmade materials, such as synthetic sponges or the like. The compressible substrates 306a, 306b can be water-permeable, such that aqueous cosmetic compositions can penetrate the body the of compressible substrate and be expelled, e.g., through holes of the compressible substrates, to evenly contact the hair during use.

[0072] In embodiments, the moving handle 301 is slidingly attached to the moving arm 305 via a sliding male member 305b that is slidingly engaged within an elongated aperture 301a. During movement of the moving handle 301 relative to the stationary handle 302, the sliding male member 305b slides within the elongated aperture301a for controlled relative movement of the moving handle 301 and the moving arm 305. In addition, in embodiments, the moving arm 305 is slidingly attached to the stationary handle 302 via a sliding male member 302a slidingly engaged within an elongated aperture 305c (of the moving arm 305). The shown example configuration of these elements, and equivalents thereof, enables an angle between the compressible substrates 306a, 306b to be minimized in both the open (unclamped) and closed (clamped) configurations, such that the compressible substrates 306a, 306b contact each other more evenly.

[0073] The shown example configuration, and equivalents thereof for minimizing the angle between the compressible substrates 306a, 306b, can be contrasted with a typical “scissor” configuration, in which a single hinge would connect two moving members for a rigid scissor movement. For example, if a typical “scissor” configuration were used for closing the compressible substrates 306a, 306b together, this could cause uneven contact therebetween, leading to stronger contacts at portions of the compressible substrates next to the hinge and expulsion of cosmetic composition therefrom, and weaker contacts at portions of the compressible substrates distal from the hinge and accumulation of excess cosmetic composition thereon. This uneven distribution of the cosmetic composition could lead to the composition being unevenly applied to the hair during a hair treatment which could frustrate use of the clamp adapter.

[0074] In the shown embodiment, the bias is produced by a spring 303 attached to the moving handle 301 at a first end thereof and attached to the stationary handle 302 at a second end thereof. The spring is biased toward an expanded configuration (e.g., as shown at FIGs 3A-3B), to distance the moving handle 301 from the stationary handle 302 and distance the moving arm 305 from the stationary arm 302 to form the open configuration.

[0075] In embodiments, the hair clamp adapter 300 further comprises a living hinge 304 that hingedly connects a proximal portion of the moving handle 301 to a proximal portion of the stationary handle 302, and is configured to prevent contact between a portion of a hand of the individual and a junction that includes the moving arm 301 and the stationary arm 302; in this manner, the living hinge 304 can prevent or reduce the risk of injury during use of a formulation delivery device comprising the hair clamp adapter 300 attached thereto.

[0076] In embodiments, the stationary handle and arm 302 comprises a proximal connector 302b and a distal connector 302c that are configured to connect the hair clamp adaptor 300 to the formulation delivery device 400, including as shown by way of anexample at FIGs 3A-3B, 4, and 5. In embodiments, the proximal connector 302b, the distal connector 302c, or both, comprises a magnet configured for a magnetic attachment of the hair clamp adapter 300 to the formulation delivery device 400 via contact with one or more corresponding magnets of the formulation delivery device 400.

[0077] In embodiments, the stationary arm 302 comprises a plurality of standoff portion slots 309a, 309b, 309c, 309d, 309e, 309f, 309g, 309h, configured as apertures, for receipt and securement of a plurality of standoff portions 416 of the formulation delivery device 104 therein (see FIGs 1, 4, and 5), for maintenance of an orientation of the hair clamp adapter 300 relative to an orientation of the formulation delivery device 104 during attachment and use.

[0078] In embodiments, including as shown by way of a non-limiting example at FIG. 4, apertures of the plurality of apertures of the second compressible substrate 306b are positioned between opposing standoff portion slots of the plurality of standoff portion slots 309a, 309b, 309c, 309d, 309e, 309f, 309g, 309h, and form a plurality of formulation pathways 307a, 307b, 307c, 307d, when aligned with a reciprocating nozzle assembly 414 of a formulation delivery device (e.g., 104 of FIG. 1). As such, in embodiments, the plurality of formulation pathways 307a, 307b, 307c, 307d are positioned for a fluid connection with the reciprocating nozzle assembly 414 for passage of the cosmetic composition from the reciprocating nozzle assembly 414 through the plurality of formulation pathways 307a, 307b, 307c, 307d via the fluid connection. As a result, in embodiments including as shown at FIG. 3B as a non-limiting example, passage of the cosmetic composition (from the reciprocating nozzle assembly 414) through the plurality of formulation pathways 307a, 307b, 307c, 307d contacts the cosmetic composition to the second compressible substrate 306b for absorption of the cosmetic composition therein for delivery to the hair of the individual through the second compressible substrate 306b. This process, passage of the cosmetic composition through the plurality of formulation pathways 307a, 307b, 307c, 307d, also passes the cosmetic composition through the plurality of apertures of the second compressible substrate 306b such that the cosmetic composition forms a plurality of formulation dribbles 308 on the second compressible substrate 306b.

[0079] In embodiments, the first and second compressible substrates 306a, 306b are removable from the moving arm 305 and the stationary arm 302, respectively. In this manner, the first and second compressible substrates 306a, 306b can be cleaned as part of maintenance, or discarded and replaced with new compressible substrates.

[0080] In various embodiments, with passage of the cosmetic composition through the plurality of formulation pathways 307a, 307b, 307c, 307d and formation of a plurality of formulation dribbles 308 on the second compressible substrate 306b, the bias can be overcome to transition the hair clamp adapter toward the clamped configuration such that the first compressible substrate 306a is evenly contacted with the plurality of formulation dribbles 308 for transfer of the cosmetic composition to the first compressible substrate 306a to evenly apply the cosmetic composition to the hair of the individual.

[0081] In various embodiments, a formulation mixer of the formulation delivery device can be implemented as a turbulent mixing chamber that comprises one or more helical mixers positioned within a fluidic pathway, and carries, mixes, and homogenizes a mixture of formulations to produce the resultant formulation or cosmetic composition to be applied to the hair. However, other types of formulation mixers can be implemented without departing from the scope and spirit of the disclosure. In the shown embodiments, a reciprocating nozzle assembly 414 comprises a plurality of nozzles (e.g., spaced apart and separated by a plurality of standoff portions 416), and is driven by a motor, such that the plurality of nozzles reciprocate back-and-forth along a track while dispensing the resultant formulation; however, alternate nozzle assembly designs can be implemented without departing from the scope and spirit of the disclosure.

[0082] In addition, in embodiments, control of a mix ratio between two or more formulations can advantageously contribute to various properties of the resultant cosmetic composition, such as potency and, as a result, the time needed to apply the composition to the hair to achieve a desired effect.

[0083] Furthermore, in embodiments, control circuitry of the formulation delivery device 104 can be configured based on a software application, executed by at least one process of the formulation delivery device 104 or another computational device, such as a smartphone, that defines relative amounts of two or more formulas to be mixed for a particular hair treatment. Accordingly, in embodiments, the control circuitry is configured to receive one or more signals from one or more formulation cartridges that corresponds to one or more formulations of the plurality of formulations, and compute the mix ratio based on the one or more signals. The signals can be received by the circuitry by way of any connection with the formulation cartridges, including but not limited to a wired connection, or a wireless connection, such as a wireless query of a radiofrequency identification (RFID) chip of a formulation cartridge, for example.

[0084] In various aspects, the disclosure provides a formulation delivery device or formulation delivery system comprising a hair clamp adapter attached thereto or configured to be attached thereto. While an example of a formulation delivery device with hair clamp adapter attached thereto 400 is shown at FIG. 5, alternate designs and configurations that implement the hair clamp adapter can be implemented without departing from the scope and spirit of the disclosure. In addition, while an example of a hair clamp adapter 300 is shown at FIGs 3A-3B, alternate designs and configurations of the hair clamp adapter 300 can be implemented without departing from the scope and spirit of the disclosure.

[0085] Referring again to FIG. 5, there is shown a hair clamp adapter 300 with a cutaway shown of an example formulation delivery device 400, depicting part of a hair treatment to apply a haircare formulation to the hair of an individual. The formulation delivery device 400 is configured to receive a formulation cartridge 402 type (including a cleaning cartridge of the same type). An embodiment of a formulation cartridge of the formulation cartridge 402 type is described herein; the formulation cartridge 402 shown in FIG. 5 shall be understood to have the same features as described there. Some embodiments of formulation delivery device 400 include the formulation cartridge 402 and / or an optional pull through adaptor 404.

[0086] Formulation delivery device 400 includes a reusable handle formed from an ABS plastic or similar rigid polymer or other material, and in embodiments is an assembly formed from a plurality of shells configured to be joined together with fastening elements such as snaps, screws, or the like. Reusable handle has a hollow, elongate gripping portion with a cartridge cavity therein which is sized and dimensioned to receive the formulation cartridge 402 type. In embodiments, the cavity includes keying features that facilitate correct insertion of the formulation cartridge 402 type. For example, 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 the latter is correctly inserted into the opening.

[0087] Formulation dispensing assembly 410 dispenses formulation or cleaning liquid from the formulation cartridge 402, and includes a pump, fluid conduits, a mixing chamber, and a reciprocating nozzle assembly 414 with nozzles that extend away from the forward end of the reusable handle in between a plurality of optional standoff portions (e.g., 416 of FIG. 1). As shown at FIG. 5, the reciprocating nozzle assembly includes a pluralityof annular nozzles that reciprocate back-and-forth along a track of the reusable handle while dispensing formulation onto a user’s skin or hair. In embodiments, the reciprocating nozzle assembly reciprocates at a reciprocating amplitude of about 7.0-12.0 mm (e.g., 8.0 mm-11.0 mm, or 9.0-10.0 mm) and / or at a reciprocating frequency of about 5.0 Hz-10.0 Hz (e.g, 6.0 Hz-9.0 Hz, 6.0 Hz-8.0 Hz), which are adjustable by the formulation routine module, cleaning routine module, user routine module, manual adjustment module, or other module (e.g, one or more modules or method steps of a software application).

[0088] In embodiments, the reusable handle also houses a number of subassemblies, including a controller 412, which includes a processor and data store storing a number of modules (e.g., circuitry configured for logic operations and / or methods), cartridge authentication interface 430, power supply, formulation dispensing assembly 410, and an optional position sensor. Formulation stored in the formulation vessel(s) 418 can be delivered and mixed within the formulation delivery device 400 for contact with the compressible substrates 306a, 306b and application to the hair of the individual. As such, formulation cartridge 402 has one or more formulation vessels 418 (e.g., pouches or packets) disposed therein, each of which has an output nozzle 420 protruding through a distal (forward) end of the formulation cartridge 402 in a configuration that fluidically connects with a corresponding formulation inlet 422 of the formulation dispensing assembly 410 when the formulation cartridge 402 is fully inserted into the cartridge cavity.

[0089] In embodiments, a button 426 disposed on the reusable handle and electrically connected to the controller 412 activates features of the formulation delivery device 400. In embodiments, depressing the button 426 activates a sleep / awake module stored in controller 412, thereby awakening formulation delivery device 400 from a sleep state to an awake state. In embodiments, pressing button 426 while a formulation cartridge is inserted into the reusable handle activates a formulation routine module stored in controller 412, thereby initiating a formulation routine.

[0090] In embodiments, pressing button 426 while a cleaning cartridge is inserted into the reusable handle activates a cleaning routine module stored in the controller 412, thereby initiating a cleaning routine. Visual indicators 428 (e.g., LEDs) disposed along the reusable handle indicate one or more of a remaining formulation quantity or a remaining battery life, e.g., based upon a dispensed time determined by the formulation routine module of the controller. Embodiments can include additional buttons and / or a different number of visual indicators 428 with different functionalities, and the illustratedembodiment is not limiting. In embodiments, visual indicator 428 is a multi-segment LED with each segment corresponding to an equal proportion of the formulation remaining in the formulation cartridge.

[0091] Controller 412 comprises logic (stored in a data store thereof), which when executed by a processor of the controller 412, causes a cartridge authentication interface 430 disposed in the reusable handle (e.g., an RFID reader) to read an encryption chip on the formulation cartridge 402 in order to authenticate the formulation cartridge 402. The encryption chip stores at least one of the formulation cartridge 402, a formulation identification, a beginning formulation quantity, a formulation expiration date, or a formulation production date.

[0092] Controller 412 also comprises logic, which when executed, causes the formulation delivery device to execute, based upon authenticating 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 through 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 which causes formulation dispensing assembly 410 to continuously or continually mix the first and second formulations, and to dispense the same from the reciprocating nozzle assembly at one or more of the following predetermined device operating parameters for as long as the button is depressed: a formulation flow rate, a reciprocating frequency, or a reciprocating amplitude.

[0093] In embodiments, controller 412 also comprises logic, which when executed, causes the formulation delivery device to execute, based upon authenticating a cleaning cartridge inserted into the reusable handles, 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 which causes 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 following predetermined device operating parameters for as long as the button is depressed: a cleaning liquid flow rate, a reciprocating frequency, or a reciprocating amplitude. In some embodiments, the cleaning liquid flow rate is higher than any formulation flow rate of oneor more of the formulation routines stored in the controller 412, for the advantage of effectively flushing residual formulation from the formulation dispensing assembly.

[0094] In another aspect, the present disclosure provides a hair coloring adapter for a formulation delivery device, such as a formulation delivery device 500 (described further herein with respect to FIG. 6A and FIG. 6B). In embodiments, formulation delivery device 500 is an example of the formulation delivery system described in detail in U.S. Patent Application Publication No. 18 / 060,258 Al, published May 30, 2024, which is incorporated by reference herein in its entirety for all purposes. However, it is to be understood that the hair coloring adapter of the present disclosure can be used on any hair coloring appliance.

[0095] The formulation delivery device 500 is configured to receive a formulation cartridge 503 type (including a cleaning cartridge of the same type). Formulation delivery device 500 includes a reusable handle 506 formed from an ABS plastic or similar rigid polymer or other material, and in some embodiments is an assembly formed from a plurality of shells configured to be joined together with fastening elements such as snaps, screws, or the like. Reusable handle 506 has a hollow, elongate gripping portion with a cartridge cavity 524 therein which is sized and dimensioned to receive the formulation cartridge 503 type. In some embodiments, the cavity includes keying features that facilitate correct insertion of the formulation cartridge 503 type. For example, some embodiments include a cartridge interface 530 disposed in the opening and having a flat docking surface that interfaces with a corresponding docking surface of the formulation cartridge 503 when the latter is correctly inserted into the opening.

[0096] Reusable handle 506 houses a formulation dispensing assembly, in addition to a controller. The formulation dispensing assembly dispenses formulation or cleaning liquid from the formulation cartridge 503, and includes a pump, fluid conduits, a mixing chamber, and a reciprocating nozzle assembly with nozzles 516 that extend away from the forward end of the reusable handle 506 in between a plurality of optional standoff protrusion 520. The reciprocating nozzle assembly includes a plurality of annular nozzles that reciprocate back-and-forth along a track of the reusable handle 506 while dispensing formulation onto a subject’s skin or hair. In some embodiments, the subject is also the user of the formulation delivery device. In some embodiments, the subject is different from the user of the formulation delivery device. In some embodiments, the reciprocating nozzle assembly reciprocates at a reciprocating amplitude 7.0-12.0 mm (e.g., 8.0 mm-11.0 mm, or9.0-10.0 mm) and / or at a reciprocating frequency of 5.0 Hz-10.0 Hz (e.g., 6.0 Hz-9.0 Hz, 6.0 Hz-8.0 Hz), which are adjustable by the formulation routine module, cleaning routine module, user routine module, manual adjustment module, or other module.

[0097] A control button 426 disposed on the reusable handle 506 and electrically connected to the controller activates features of the formulation delivery formulation delivery device 500 described above. In some embodiments, depressing the control button 426 activates features such as a sleep / awake module stored in controller, thereby awakening formulation delivery formulation delivery device 500 from a sleep state to an awake state. In some embodiments, pressing control button 426 while a formulation cartridge is inserted into the reusable handle 506 activates a formulation routine module stored in controller, thereby initiating a formulation routine. In certain examples, the control button 426 may be used to initialize the formulation delivery device 500 or place the formulation delivery device 500 in a state to perform certain functions, such as one or more of: calculating a mixture ratio of the components of the coloring formulation; entering a cleaning or purging mode; heating the formulation; gathering data from the formulation containers, such as volume remaining, mixture ratios, color information, etc.; sending and receiving signals; analyzing data regarding user preferences; gathering data from sensors; providing status indication to the user, such as power output level, battery life, formulation volume remaining, sensor data, data connection information, etc.; and communicating with auxiliary equipment. In embodiments, the control button 426 is capable of pressure sensitive operation, such that applying a higher pressure to the control button 426 causes a variable response, such as, for example, causing the formulation to flow faster, the nozzles to move faster, or the like. In embodiments, various operating parameters can be controlled by the use of a smart device, such as a phone (as described in detail in U.S. patent application Ser. No. 14 / 586,138, which is incorporated by reference herein in its entirety for all purposes).

[0098] In some embodiments, pressing control button 426 while a cleaning cartridge is inserted into the reusable handle 506 activates a cleaning routine module stored in the controller, thereby initiating a cleaning routine. Visual indicators 526 (e.g., LEDs) disposed along the reusable handle 506 indicate one or more of a remaining formulation quantity or a remaining battery life, e.g., based upon a dispensed time determined by the formulation routine module of the controller. Some embodiments include additional buttons and / or a different number of visual indicators 526 with different functionalities,and the illustrated embodiment is not limiting. In some embodiments, visual indicators 526 are a multi-segment LED with each segment corresponding to an equal proportion of the formulation remaining in the formulation cartridge.

[0099] The controller comprises logic (stored in a data store thereof), which when executed by a processor of the controller, causes a cartridge authentication cartridge interface 530 disposed in the reusable handle 506 (e.g., an RFID reader) to read an encryption chip 528 on the formulation cartridge 503 in order to authenticate the formulation cartridge 503. The encryption chip 528 stores at least one of the formulation cartridge 503, a formulation identification, a beginning formulation quantity, a formulation expiration date, or a formulation production date.

[0100] The controller also comprises logic, which when executed, causes the formulation delivery device to execute, based upon authenticating the formulation cartridge 503, a formulation routine that dispenses a mixed formulation (of the first formulation and the second formulation) from the formulation cartridge 503 through 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 which causes the formulation dispensing assembly to continuously or continually mix the first and second formulations, and to dispense the same from the reciprocating nozzle assembly at one or more of the following predetermined device operating parameters for as long as the button is depressed: a formulation flow rate, a reciprocating frequency, or a reciprocating amplitude.

[0101] In some embodiments, controller also comprises logic, which when executed, causes the formulation delivery device to execute, based upon authenticating a cleaning cartridge inserted into the reusable handles, 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 which causes the formulation dispensing assembly to continuously or continually dispense a cleaning liquid (e.g., water) from the reciprocating nozzle assembly at one or more of the following predetermined device operating parameters for as long as the button is depressed: a cleaning liquid flow rate, a reciprocating frequency, or a reciprocating amplitude. In some embodiments, the cleaning liquid flow rate is higher than any formulation flow rate of oneor more of the formulation routines stored in the controller, for the advantage of effectively flushing residual formulation from the formulation dispensing assembly.

[0102] In some embodiments, the formula delivery system includes a first formulation source storing a first liquid formulation. In some embodiments, the first liquid formulation has a dye load from 0.05% to 5.5%. In some embodiments, the first liquid formulation is ammonia-free. In some embodiments, the first liquid formulation comprises ammonia and monoethanolamine. In some embodiments, the first liquid formulation comprises resorcinol. In some embodiments, the first liquid formulation is free of resorcinol and resorcinol derivatives.

[0103] In some embodiments, the formula delivery system includes a second formulation source storing a second liquid formulation. In some embodiments, the second liquid formula is a developer. In some embodiments, the second liquid formula comprises at least hydrogen peroxide. In some embodiments, the second liquid formula is a cream or a liquid.

[0104] In some embodiments, when the first liquid formula and the second liquid formula are mixed, the second liquid formula is activated. In some embodiments, the mixed formulation has a mixed formulation viscosity of at least 2.0 Pa-s. In some embodiments, the mixed formulation viscosity is from 2.0 Pa-s to 4.0 Pa-s.

[0105] The output area of the reusable handle 506 includes a plurality of elongate nozzles 516 extending from a manifold housing 508 coupled to or formed on the reusable handle 506. The elongate nozzles 516 are configured to discharge the coloring formulation through a plurality of outlet apertures 518 in the end of the nozzle 516 upon use of the formulation delivery device 500. In embodiments, the nozzles 516 are arranged in one or more rows along the length of the head of the reusable handle 506, generally in a direction along the length of the formulation delivery device 500, as shown in the FIGURES. In other embodiments, the nozzles 516 are suitably placed at an angle with respect to the length of the formulation delivery device 500.

[0106] In embodiments, the nozzles 516 have a length between about 0.5 cm and about 4.0 cm from the manifold housing 508 to the end of the nozzles 516 at the outlet apertures 518. In other embodiments, the nozzles 516 have a length between about 1.4 cm and about 1.8 cm from the manifold housing 508 to the end of the nozzles 516 at the outlet apertures 518. In other embodiments, the nozzles 516 have a length of about 1.6 cm fromthe manifold housing 508 to the end of the nozzles 516 at the outlet apertures 518. In further embodiments, any length of nozzle is suitably used.

[0107] In the illustrated embodiment, a plurality of standoff protrusions 520 extend outwardly substantially in the direction of the nozzles 516 from the manifold housing 508 in one or more rows. In this regard, substantially in the direction of the nozzles 516 is intended to refer to within and angle of about 25 degrees of the direction along the length of the nozzles 516. In the depicted embodiment, first and second rows of standoff protrusions 520 are positioned along either side of a single row of elongate nozzles 516. In embodiments, the standoff protrusions 520 may be disposed at an angle relative to the plurality of nozzles 516. (For example, see U.S. Patent Application Publication No. 15 / 339,551, which is incorporated by reference herein in its entirety for all purposes.)

[0108] In embodiments, a standoff protrusion of the standoff protrusions 520 has a length (measuring between the manifold housing 508 to an end of the standoff protrusions 520) such that the end of the standoff protrusions 520 and the outlet apertures 518 of the nozzles 516 is substantially coplanar. In other embodiments, the standoff protrusions 520 have a length (from the manifold housing 508 to the end of the standoff protrusion 520) such that the standoff protrusions 520 are longer than a length of the nozzles 516 (measuring between the manifold housing 508 to an end of the nozzles 516). In this regard, during use, the standoff protrusions 520 would contact an application surface, such as a localized portion of the scalp, and space the outlet aperture 518 of the nozzles 516 away from the application surface to provide a gap for discharge of the coloring formulation through the outlet aperture 518. In the embodiments where the standoff protrusions 520 are longer than the plurality of nozzles 516, the standoff protrusions 520 are between about 0.1 mm and 5.0 mm longer than the length of each of the plurality of nozzles 516. In other embodiments, the standoff protrusions 520 are between about 0.5 mm and 1.5 mm longer than the length of each of the plurality of nozzles 516. In other embodiments, the standoff protrusions 520 are about 1.0 mm longer than the length of each of the plurality of nozzles 516.

[0109] As best seen in FIG. IB, a hair coloring adapter 600 is shown to attach to the consumable assembly reusable handle 506 substantially over the nozzles 516 and standoff protrusions 520. As will be described further below, hair coloring adapter 600 includes a bristle adapter 602 and an adapter cap 604. When hair coloring adapter 600 couples to the reusable handle 506, the plurality of nozzles 516 interface with formulationports 624 (depicted in FIG. 2B) within an adapter base 606 on the hair coloring adapter 600. In embodiments, hair coloring adapter 600 couples directly to the reusable handle 506. In embodiments, hair coloring adapter 600 couples to the plurality of standoff protrusions 520. In embodiments, hair coloring adapter 600 couples to the plurality of standoff protrusions 520 and to the reusable handle 506. In embodiments, hair coloring adapter 600 is one of several hair coloring adapters 600 that are configured to provide customization to the formulation delivery device 500, as described further below with respect to FIG. 2A - FIG. 5.

[0110] Turning next to FIG. 2A and FIG. 2B, an embodiment of a hair coloring adapter 600 is shown. FIG. 2A is a side perspective view of a hair coloring adapter 600 for applying hair dye to alternating strands of hair of a subject. FIG. 2B is a top view of the hair coloring adapter of FIG. 2A.[oni] In some embodiment, hair coloring adapter 600 is configured to clip onto a segment of the hair of the subject, separating the segment of hair into target strands and non-targeted strands. In this way, hair coloration can be affected in an alternating pattern to achieve a highlighting effect. One advantage of such an arrangement is that a user can customize the regions of the subject’s hair that are intended to receive the hair coloring treatment.

[0112] In the illustrated embodiment, hair coloring adapter 600 is shown to include a bristle adapter 602 and an adapter cap 604. Bristle adapter 602 is shown to include an adapter base 606, a plurality of support structures, such as support posts 612, a plurality of formulation application zones 614, and a plurality of non-application zones 626. In embodiments, the support structures can be a continuous support segment or wall, or the like. Adapter base 606 has a first side of the adapter base 608 and a second side of the adapter base 610. In embodiments, first side of the adapter base 608 is configured to couple to a formulation delivery device, such as formulation delivery device 500 depicted in FIG. 1A. In embodiments, the reusable handle 506 of the formulation delivery device 500 includes magnetic attachment points which can couple to corresponding magnets in the adapter base 606. In embodiments, the reusable handle 506 and the adapter base 606 include a mating pair of snap-fit attachments, such as snap-fit attachments with a quickrelease tab. In some embodiments, the formulation ports 624 comprise an inner diameter configured to snugly couple to the plurality of nozzles 516 on formulation delivery device 500, thereby detachably coupling the adapter base 606 to the formulation delivery device500. In embodiments, adapter base 606 is configured to slide lock onto the formulation delivery device. However, it is to be understood that any suitable coupling mechanism can be used and falls within the scope of the present disclosure.

[0113] When hair coloring adapter 600 is coupled to the formulation delivery device, such as formulation delivery device 500, the nozzles 516 are fluidly connected to formulation ports 624, thereby allowing formulation to flow from the formulation delivery device 500 and through the hair coloring adapter 600 onto the hair of a subject. In embodiments, the formulation ports 624 couple directly to the nozzles 516. In embodiments, the formulation ports 624 couple to the nozzles 516 via a length of flexible tubing.

[0114] In the illustrated embodiment, the support posts 612 of the bristle adapter 602 protrude from the second side of the adapter base 610. The support posts 612 include a top portion which is configured to couple with the adapter cap 604. In this way, bristle adapter 602 and adapter cap 604 are configured to detachably couple to one another when bristle adapter 602 is placed on a portion of the subject’s hair, thereby clipping the segment of hair into the hair coloring adapter. When hair coloring adapter is clipped onto the portion of the subject’s hair, the hair is further portioned between the plurality of formulation application zones and the plurality of non-application zones, thereby allowing for formulation to be applied to alternating portions of the subject’s hair. In embodiments, bristle adapter 602 and adapter cap 604 clip together, such as via a magnetic interfacing system. However, any suitable coupling method can be used and falls within the scope of the present disclosure, such as interlocking flexible tabs, slide-lock tabs, clamping members, and the like. Adapter cap 604 is configured to detachably couple to bristle adapter 602 when bristle adapter 602 is placed on a portion of the subject’s hair, thereby clipping the segment of hair into the hair coloring adapter 600.

[0115] In embodiments, the support posts 612 include a height defined from the base of the support post 612 on the second side of the adapter base 610 to the opposing end of the support post 612. The height of support posts 612 can be customized, thereby enabling the hair coloring adapter 600 to accept a larger or smaller selection of strands of hair from the subject. The advantage of accepting a larger selection of strands of hair is it allows the hair coloring adapter 600 to more quickly apply hair coloration treatment to an entire head of hair. The advantage of accepting a smaller selection of strands of hair is increased layering and customizability of the highlighting treatment. In embodiments, theheight ofthe support posts 612 can be 0.5 cm, 1.0 cm, 1.5 cm, 2.0 cm, 2.5 cm, 3.0 cm, 3.5 cm, 4.0 cm, 4.5 cm, or 5.0 cm.

[0116] In embodiments, adapter cap 604 couples to support posts 612, thereby substantially enclosing a region between the formulation ports 624 and the adapter cap 604. In the illustrated embodiment, adapter cap 604 is shown to include two end portions which rest upon the top portion of the support posts 612 and affix to support posts 612, such as by clipping into place, by a magnetic attachment system, or the like.

[0117] In the illustrated embodiment, a plurality of crossbeams connect the two end portions of the adapter cap 604, thereby creating a cage-like structure. Such a structure has the advantage of improving visibility beneath adapter cap 604 for the user of hair coloring adapter 600 to visually identify if strands of hair are segmented into the various formulation application zones 614 and non-application zones 626. However, it is to be understood that adapter cap 604 can be in the form of any structure, such as that described in further detail with respect to FIG. 5 herein below.

[0118] In embodiments, adapter cap 604 is permanently coupled to a first set of support structures, such as support posts 612, on a first side of the hair coloring adapter 600 and detachably coupled to a second set of support structures, such as support posts 612, on a second side of the hair coloring adapter 600. An advantage of such a configuration is that adapter cap 604 and bristle adapter 602 remain connected between uses, thereby preventing the user from misplacing one of the two components.

[0119] Referring to FIG. 2B - FIG. 4B, the formulation application zone 614 will now be discussed. The bristle adapter 602 is configured to include a plurality of formulation application zones 614. In the illustrated embodiment of FIG. 2B, there are five formulation application zones 614. However, it is to be understood that the bristle adapter 602 can include two formulation application zones 614, three formulation application zones 614, four formulation application zones 614, five formulation application zones 614, six formulation application zones 614, seven formulation application zones 614, or eight or more formulation application zones 614.

[0120] An individual formulation application zone 614 can include one or more comb segments 616, one or more brush bristle heads 620, and one or more formulation ports 624. For example, formulation application zone 614 can include a first comb segment 616 and a second comb segment 616 disposed on either side of the brush bristle heads 620 and the formulation port 624, thereby substantially enclosing the brush bristle heads 620and the formulation port 624. An individual comb segment 616 includes one or more comb tines 618. As best seen in FIG. 3, the formulation port 624 defines a bore through the adapter base 606, placing the first side of the adapter base 608 in fluid communication with the second side of the adapter base 610. Formulation port 624 can be coupled to a source of formulation such as nozzle 516 of formulation delivery device 500.

[0121] Turning back to FIG. 2B - FIG. 4B, in embodiments, a formulation application zone 614 includes two comb segments 616. In the illustrated embodiment, comb segment 616 is an arrangement of four comb tines 618 substantially in a row from a front to a rear side of the second side of the adapter base 610. A spacing between adjacent comb tines 618 can have several advantages, including improving ease of cleaning the hair coloring adapter 600 between uses, minimizing material costs for manufacturing, and improving air flow during the application of formulation to the hair of a subject. However, it is to be understood that comb segment 616 can also comprise a single continuous piece of material.

[0122] Comb tines 618 protrude from the adapter base 606. In embodiments, comb tines 618 protrude from adapter base 606 and are substantially perpendicular to adapter base 606. In embodiments, comb tine 618 protrude from adapter base 606 and form an angle with respect to the adapter base 606, such as an 85° angle, an 80° angle, a 75° angle, a 70° angle, a 65° angle, or a 60° angle. A perpendicular orientation of comb tines 618 relative to the adapter base 606 has several advantages, including consistency in the fraction of hair captured and held within any one of the formulation application zones 614. However, other angles can advantageously hold and retain segments of hair within the formulation application zone 614 more securely during application. Thus, the angle of the comb tines 618 can provide options for customizing the hair coloring adapter 600.

[0123] In embodiments, a comb tine 618 comprises a height a height defined from the base of the comb tine 618 on the second side of the adapter base 610 to the opposing end of the comb tine 618. The height of comb tine 618 can be customized to contain a larger or smaller sample of hair of the subject. The advantage of accepting a larger selection of strands of hair is it allows the hair coloring adapter 600 to more quickly apply hair coloration treatment to an entire head of hair. The advantage of accepting a smaller selection of strands of hair is increased layering and customizability of the highlighting treatment. In embodiments, the height of the comb tine 618 can be 0.5 cm, 1.0 cm, 1.5 cm, 2.0 cm, 2.5 cm, 3.0 cm, 3.5 cm, 4.0 cm, 4.5 cm, or 5.0 cm. In embodiments, the height ofcomb tine 618 is substantively identical to the height of support post 612, such that a tip of comb tine 618 contacts adapter cap 604 when adapter cap 604 is clipped onto support post 612. In embodiments, comb tines 618 include additional coupling means, such as magnets, to provide additional coupling between adapter cap 604 and bristle adapter 602. In embodiments, the height of comb tine 618 is less in magnitude than the support post 612.

[0124] In embodiments, a comb tine 618 comprises a length with a first side and a second side. The first side is coupled to the adapter base 606 and comprises a width that is greater in magnitude than a width of the second side of the comb tine 618. In embodiments, the width of comb tine 618 at the first side is substantially identical to the width of comb tine 618 at the second side. In embodiments, comb tines 618 comprise an average width of 5 mm, 4 mm, 3 mm, 2 mm, or 1 mm. In embodiments, comb tines 618 comprise a material composition that is substantively identical to a material composition of the adapter base 606. In embodiments, comb tines 618 comprise a polymeric material, such as an acrylonitrile butadiene styrene (ABS) plastic, a high-density polyethylene (HDPE) plastic, a rubberized material, and the like.

[0125] The non-application zone 626 is defined as the space between adjacent formulation application zones 614. For example, a non-application zone 626 can be defined by the space between the second comb segment 616 of a first formulation application zone 614 and the first comb segment 616 of a second formulation application zone 614. In embodiments, a formulation application zone 614 defines an application zone width, and a non-application zone 626 defines a non-application zone width. In embodiments, the application zone width is greater in magnitude than the non-application zone width. In embodiments, the application zone width is substantially identical in magnitude with the non-application zone width. In embodiments, the application zone width is smaller in magnitude than the non-application zone width.

[0126] The relative magnitudes of the application zone width and the non- application zone width can be advantageously selected to expose a greater or smaller portion of the hair of a subject to a coloring formulation. In embodiments, the magnitude of the width of a plurality of non-application zones 626 can vary, such that some non- application zones 626 have a greater magnitude of width from other non-application zones 626. In embodiments, the magnitude of the width of a plurality of formulation application zones 614 can vary, such that some formulation application zones 614 have a greater magnitude of width from other formulation application zones 614. Such an arrangementcan allow the hair coloring adapter 600 to be used to achieve a textured or layered coloring scheme in the hair of the subject.

[0127] Turning back to the formulation application zones 614, and as best seen in FIG. 3 - FIG. 4B, an individual brush bristle head 620 includes a plurality of bristles 622. In embodiments, the formulation application zone 614 comprises two or more brush bristle heads 620. A brush bristle head 620 protrudes from the adapter base 606. When a formulation application zone 614 includes two comb segments 616, the brush bristle head 620 protrudes from the adapter base 606 and is disposed between a pair of the comb segments 616. The brush bristle head 620 is configured to surround the formulation port 624. For example, when there are two brush bristle heads 620, one brush bristle head 620 is positioned along an outer edge of the adapter base 606 with the formulation port 624 positioned substantively in the middle. In embodiments, a single brush bristle head 620 is an annular brush bristle head 620 and is positioned to substantially surround the formulation port 624. In embodiments, a single brush bristle head 620 forms a rectangular- toroid cross section.

[0128] In embodiments, a bristle 622 of the plurality of bristles 622 defines a height and a width. Bristle 622 protrudes from the adapter base 606. In embodiments, the height of bristle 622 and the height of comb tine 618 are substantively identical. In embodiments, the magnitude of the height of bristle 622 is greater than the magnitude of the height of comb tine 618. In embodiments, the magnitude of the height of bristle 622 is smaller than the magnitude of the height of comb tine 618. In embodiments, a magnitude of the width of bristle 622 is smaller than the magnitude of the width of comb tine 618. In embodiments, bristle 622 comprises an average width of 500 pm, 450 pm, 400 pm, 350 pm, 300 pm, 250 pm, 600 pm, 150 pm, 500 pm, 90 pm, 80 pm, 70 pm, 60 pm, or 50 pm.

[0129] In embodiments, bristle 622 comprises a polymeric material, such as ABS plastic, HDPE plastic, a rubberized material, and the like. In embodiments, bristle 622 is a hair, such as a horse hair, a boar hair, and the like. The relatively small average width of the bristles 622 as compared to the comb tines 618 provides advantages in the application of hair formulation. A thinner bristle 622 is more flexible and allows for a greater number of bristles 622 within a given surface area of adapter base 606. This thus increases the total contact surface area between bristles 622 and the hair strands of a subject, thereby improving the quality of formulation transfer. On the other hand, a relatively thick averagewidth of the comb tines 618 provides a rigid barrier, thereby maintaining a desired segmentation of the subjects hair into various segments of hair strands.

[0130] In embodiments, the brush bristle head 620 is configured to wipe formulation onto the hair of a subject. For example, when formulation exudes from the formulation port 624, it removably adheres to the brush bristle head 620. As the user draws the hair coloring adapter 600 along the strand of hair to which it is clipped, the bristles 622 of brush bristle head 620 interweave with individual hairs of the subject, thereby transferring formulation to the hair of the subject. Only a portion of the total formulation exuded to brush bristle head 620 transfers at a given time, thereby enabling even transfer of formulation to the hair of the subject.

[0131] In embodiments, the brush bristle head 620 is configured to wipe formulation off the hair of a subject. For example, after a first brush bristle head 620 wipes formulation onto the hair of the subject, a second brush bristle head 620 interweaves with individual hairs of the subject. The second brush bristle head 620 includes less formulation, and thus draws up excess formulation from the hair of the subject as the user draws the hair coloring adapter 600 along the strand of hair to which it is clipped. In this way, consistency of formula application can be achieved while minimizing wasted material and minimizing mess during an after-application cleanup process. Such an arrangement also improves the consistency of results, such as when the amount of hair formulation to a region of hair changes the coloring effect on that hair.

[0132] In embodiments, an individual formulation application zone 614 is substantially identical to the other formulation application zones 614. In embodiments, one or more individual formulation application zones 614 includes a different structure from the other formulation application zones 614 as discussed further above with respect to the various embodiments of the formulation application zone 614. In various embodiments, the various features described herein are mixed and matched to achieve a desired coloring effect. For example, a formulation application zone 614 substantively to the middle of the hair coloring adapter 600 can be configured to apply a greater amount of formulation than a formulation application zone 614 near either end of the hair coloring adapter 600, thereby improving blending of coloring effect between a first use of the hair coloring adapter 600 and a second use of hair coloring adapter 600 on a different segment of the subjects hair.

[0133] As best seen in FIG. 2B, in embodiments, the formulation application zones 614 and the non-application zones 626 are arranged in an alternating pattern wherebyno formulation application zone 614 is directly adjacent to a second formulation application zone 614. However, it is to be understood that other arrangements are possible, such as where two formulation application zones 614 are separated by multiple comb segments 616, thereby adding additional separation between adjacent formulation application zones 614. In embodiments, multiple formulation application zones 614 can be directly adjacent to one another, for example, where a first formulation application zone 614 shares a common comb segment 616 with a second formulation application zone 614, thereby resulting in two or more formulation application zones 614 with no intervening nonapplication zones 626.

[0134] A second embodiment of formulation delivery device 500 will now be described with reference to FIG. 5. The formulation delivery device 500 is substantially identical to the hair coloring adapter 600, with the exception that the adapter cap 905 of the formulation delivery device 500 differs from the adapter cap 604 of the hair coloring adapter 600. Thus, parts of the formulation delivery device 500 will be labeled with identical part numbers as the hair coloring adapter 600 except in the ‘500 series. Moreover, only the adapter cap 905 and how it impacts the function of formulation delivery device 500 will be described in detail.

[0135] Formulation delivery device 500 is shown to include adapter cap 905. Adapter cap 905 comprises a single continuous top portion. In embodiments, adapter cap 905 couples to support posts 612, thereby substantially enclosing a region between the formulation ports (not shown) and the adapter cap 905. Adapter cap 905 is configured to contact a plurality of support structures (not shown), such as support post 612, described further herein above with respect to FIG. 2A - FIG. 4B, such as by clipping into place, by a magnetic attachment system, or the like. Advantageously, by comprising a single detachable piece, adapter cap 905 can provide improved cleaning between uses of formulation delivery device 500, and improved containment of hair strands and formulation.

[0136] In embodiments, adapter cap 905 is permanently coupled to support structures on a first side of the formulation delivery device 500 and detachably coupled to support structures on a second side of the formulation delivery device 500. An advantage of such a configuration is that adapter cap 905 and bristle adapter 902 remain connected between uses, thereby preventing the user from misplacing one of the two components.

[0137] In an aspect, the present disclosure provides a method for dying alternating hair strands of a subject. Referring to FIG. 6, method 1000 illustrates a hair dying method in accordance with an embodiment of the present disclosure. In block 5002, a hair coloring adapter, such as hair coloring adapter 600, described further herein with respect to FIG. 2A - FIG. 4B, is clipped onto a first segment of the hair of the subject.

[0138] In block 5004, the hair coloring adapter is coupled to a formulation delivery device, such as formulation delivery device 500, described further herein with respect to FIG. 1A - FIG. IB. In block 5006, the formulation delivery device is activated, such as by pressing control button 426 to initiate a flow of formulation, such as through nozzles 516. In block 5008, the user draws the hair coloring adapter along the clipped segment of the hair of the subject, thereby brushing hair formulation onto the clipped segment of the hair of the subject.

[0139] In embodiments, the hair coloring adapter includes a bristle adapter and an adapter cap detachably coupled with the bristle adapter. In embodiments, the bristle adapter includes an adapter base, a plurality of support structures protruding from the adapter base and configured to couple with the adapter cap, a plurality of formulation application zones disposed on the second side of the adapter base, a plurality of nonapplication zones disposed on the second side of the adapter base, and a plurality of formulation ports defining a fluid pathway from the first side of the adapter base to the second side of the adapter base.

[0140] In optional block 1010, the user unclips the hair coloring adapter from the first segment of hair, and subsequently clips the hair coloring adapter onto a second segment of hair. After completing optional block 1010, method 1000 can be repeated, starting with block 5004.Terminology
