[0024] The foregoing aspects and many associated advantages of the present invention will be more easily understood as they are better understood with reference to the detailed description that follows, when taken in conjunction with the accompanying drawings. Detailed description

[0025] At least some hair care formulations can be relatively thick or viscous and difficult to apply to the hair in the correct amounts. This results in under-application of the hair care formulation due to the difficulty of applying the composition and over-application due to the difficulty of removing the excess composition. Using approaches such as those disclosed herein, fluid hair care formulation systems and devices, such as the Colorsonic™ device marketed by L'Oréal as a non-limiting example, can be advantageously configured for the correct and precise application of hair care formulas, including viscous formulations, to The disclosed approaches allow for the cleansing and treatment of hair without under- or over-application of the formulations. They are capable of making controlled contact with and compressing the hair, and delivering consistent amounts of fluid formulations to the hair using a hair clip adapter that incorporates one or more compressible materials, such as one or more sponges. These sponges transmit the formula through the tightly packed strands of hair, allowing the user to apply the formulation and wipe away excess with the edges of the sponges in a scraping motion. The disclosed approaches also improve formulation delivery systems for even distribution of the formulation over multiple strands of hair, enabling consistent results.

[0026] A formulation dispensing system can be configured for use with any one of a plurality of formulation cartridges. By way of non-limiting example, [Fig. 1] shows a side perspective view of an example formulation dispensing system, and [Fig. 2] shows a rear perspective view of an example formulation cartridge. A formulation dispensing system 100 can include a formulation cartridge 200. The formulation dispensing system 100 shown is an example of a formulation dispensing system as described in detail in US Patent Application Publication No. US20240172858A1, published on May 30, 2024.However, it should be understood that aspects and embodiments of this disclosure may be used with any formulation delivery system for hair coloring and / or hair bleaching, without departing from the scope and spirit of the disclosure.

[0027] The example formulation delivery system 100 shown includes a formulation product range 102, a formulation delivery device 104, and a formulation 106 (for example, within a liquid reservoir 206 of a formulation cartridge 108, shown in cross-section in Figures 1 and 2), which together enable the application of a cosmetic composition to a person's hair for a personalized hair treatment experience, such as hair coloring and / or bleaching. The formulation product range 102 includes formulation cartridges 108, and the formulation cartridges 108 may be of the same type (or a common type) of cartridge configured to be interchangeable and used with the formulation delivery device 104.

[0028] The formulation product range 102 may include a cosmetic composition in the form of a hair bleaching formulation, which may include a bleaching product formula and a developer formula which, when mixed together by the formulation delivery device 104, form the cosmetic composition to be applied to a person's hair. In embodiments, a product range of formulation 102 may include one or more cartridges that comprise: a bleaching product formula and a developer, a permanent hair dye and a developer, a semi-permanent hair dye and a developer, a shampoo, a conditioner, a hair growth treatment such as minoxidil, a hair protein treatment, a hair disulfide bond repair treatment, a liquid scalp treatment, or the like.

[0029] In embodiments, a formulation product range 102 may include a cleaning cartridge containing a cleaning solution for cleaning the formulation dispensing device 104 before and / or after use. A cleaning solution may enable a person to clean the formulation dispensing device 104 by performing a cleaning routine, with the device and the cleaning solution cartridge, which passes a cleaning liquid (e.g., water, saline) from the cleaning cartridge through the fluid channels of the formulation dispensing device 104. This removes residual formulation from the formulation dispensing device 104. Advantageously, the cleaning cartridge and the cleaning routine allow a significant portion of the formulation dispensing device 104 to be reused for different formulations, thereby reducing waste and costs.The cleaning cartridge may include a refillable cleaning fluid reservoir located inside the external housing, which is fluidically connected to the plurality of outlet nozzles. Thus, a user can fill the cleaning fluid reservoir with a cleaning fluid such as water, run a number of cleaning programs on the formulation delivery device 104, and refill the cleaning fluid reservoir.

[0030] The formulation cartridge 108 shown has an elongated shape and dimensions configured for insertion into a handle of the formulation delivery device 104, in particular into a cartridge cavity of the handle, to mix and dispense the cosmetic composition from the formulation delivery device 104. All or substantial parts of a formulation cartridge 108 may be composed of one or more recyclable elements, for example, to manage the environmental impact of the system and the product range.

[0031] The formulation cartridge 108 may include a plurality of liquid outlet nozzles, which are shaped and positioned at a distal (front) end of the formulation cartridge 108 in a configuration that fluidly connects to a corresponding plurality of liquid inlets (for example, the first inlets formulation) of the formulation delivery device 104. In some embodiments, the liquid outlet nozzles are valves of formulation containers (e.g., pouches or packets) arranged in the formulation cartridge 108.

[0032] Figure 2 shows a formulation cartridge 200 that is compatible with any of the formulation delivery systems, formulation delivery devices, and formulation product ranges described herein. However, the formulation delivery systems, formulation delivery devices, and formulation product ranges described herein do not necessarily have to use the durable formulation cartridge 200 shown in Figure 2.

[0033] In some embodiments, the formulation cartridge 200 is durable and designed to reduce waste and environmental impact while providing a user-friendly experience. It includes two main components: a handle portion 202 and a disposable formulation cartridge refill unit 212 (hereafter referred to simply as the refill unit 212) configured to slide reversibly into the handle portion 202. The formulation cartridge 200 is constructed so that the handle portion 202 can be reused indefinitely and the refill units 212 can be easily replaced after the formulation they contain is depleted. Furthermore, the refill unit 212 can be configured to be disassembled into smaller components, some of which can be recycled in some embodiments and others disposed of.Thus, the Formulation 200 cartridge uses an innovative structure to reduce waste and improve the user experience.

[0034] In some embodiments, the handle portion 202 is shaped, dimensioned, and constructed to be repeatedly inserted into the cartridge cavity of the formulation delivery device. Therefore, the handle portion 202 may 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. The refill unit 212 includes a refill pack comprising a shell enclosing at least one formulation container (e.g., a pack, a pouch, or other container), for example, a first formulation pouch and a second formulation pouch, and a valve frame coupled to the refill pack, for example, a front body portion 210. In some embodiments, at least one formulation container is a liquid reservoir 206.The first formulation pouch and the second formulation pouch can contain a first formulation (for example, a bleaching product formula) and a second formulation (for example, a developer formula), respectively. The refill unit 212 may include a package sleeve. In some embodiments, a... The formulation container may include a formulation packet and an outlet nozzle.

[0035] In some embodiments, the first and second formulation pouches of the formulation cartridge 200 may each have a volume of approximately 40 ml to approximately 70 ml, approximately 50 ml to approximately 60 ml, approximately 40 ml to approximately 65 ml, approximately 40 ml to approximately 60 ml, approximately 40 ml to approximately 55 ml, approximately 40 ml to approximately 50 ml, approximately 45 ml to approximately 70 ml, approximately 50 ml to approximately 70 ml, approximately 55 ml to approximately 70 ml, approximately 60 ml to approximately 70 ml, or approximately 55 ml. In some embodiments, the first and second formulation pouches may have different volumes. In some embodiments, the refill unit 212 stores only one formulation container.

[0036] In embodiments, the first and second formulations may be independently selected from any of the formulations described herein, or their equivalents in the art, and may include at least one non-fluid formulation, for example, a bleaching 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 hair disulfide bond repair treatment, a liquid hair treatment, a liquid scalp treatment, and any combination thereof, or the like. In some embodiments, the first and second formulations are different. For example, in some embodiments, the first formulation is a bleaching product formula and the second formulation is a developer.In other embodiments, the first formulation and the second formulation are identical (for example, a conditioner or a scalp treatment formulation).

[0037] In embodiments, the formulation pouches include a package containing a formulation and a valve-forming means comprising outlet nozzles 208 enabling selective fluidic coupling of the refill unit to a dispensing nozzle unit of a formulation delivery device when the formulation cartridge 200 is received in the portable formulation dispensing device. A representative valve-forming means includes a valve through which the formulation exits the package containing the formulation. Examples of formulation containers are described in International Patent Application Publication WO2019067336A2, published April 4, 2019, and US Patent Application Publication US20210196021A1, published July 1, 2021.

[0038] In some embodiments, the shell (i.e., the external part) of the cartridge refill unit 212 has an elongated shape designed to fit into the reusable handle portion 202. The shell surrounds and protects the first pocket The formulation pouch and the second formulation pouch engage with the valve frame (described below). Thus, the shell acts as a protective container for the formulation pouches during handling before loading into the formulation dispensing device.

[0039] In some embodiments, the casing has a total length between 150 and 250 mm (for example, 175 to 225 mm, 185 to 215 mm, 195 to 205 mm, or 200 mm) and a maximum cross-sectional dimension of 25 to 50 mm (for example, 30 to 45 mm, 35 to 40 mm, or 36 mm). The casing has a rear body portion and a slender front body portion 210, for example, a neck portion, extending away from the body portion. The body portion and the slender front body portion 210 are generally aligned in a common longitudinal direction to allow assembly with the reusable handle portion 202, and to allow insertion into the cartridge cavity of the formulation delivery device. In some embodiments, the shell is constructed at least partially from a recyclable or recycled material, for example a paper material such as an injection-molded paper material or a die-cut structured paper (for example, cardboard).In some embodiments, the shell is formed from a single piece of injection-molded paper material. In embodiments where the shell is formed from paper, the paper has a weight between 8 and 12 points (for example, 8.5 points, 9.0 points, 9.5 points, 10.0 points, 10.5 points, 11.0 points or 11.5 points), to provide sufficient rigidity without introducing an excess of disposable material.

[0040] In some embodiments, the rear body portion of the shell has a larger cross-sectional area than the front body portion 210 when viewed in a plane perpendicular to the longitudinal direction of the formulation cartridge 200. A bump or bulge provides the largest cross-sectional area of ​​the rear body portion relative to the slender front body portion 210. Advantageously, the bump or bulge allows the use of larger formulation pouches. Furthermore, the bump or bulge forms a stop that butts against a corresponding inner face of the handle portion 202 and fixes the longitudinal position of the shell during use, for example, by a tight fit.

[0041] In some embodiments, the slender front body portion 210 of the shell is dimensioned to fit into the handle portion 202 and to protrude into the cartridge cavity of the formulation delivery device during use. The front body portion 210 couples to the valve frame. To facilitate secure connection and alignment with the valve frame, the front body portion 210 includes a valve frame coupling means, for example, at least one coupling tab configured to selectively engage with the valve frame. In the In the illustrated embodiment, the front body portion 210 includes a single coupling tab extending away from one of its front ends. The coupling tab includes an engagement element, for example a notch or a raised protrusion, shaped and dimensioned to engage with a complementary opening in the valve frame.

[0042] In some embodiments, the shell configurations can be diverse and varied. For example, the shell can be a double-shell configuration formed by at least two partial shells (in this embodiment, the first half 203 and the second half 204) coupled in an articulated manner. In other embodiments, the shell includes a different number of partial shells, for example, three or four partial shells that 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. The alignment of the first half 203 and the second half 204 allows the front body portion 210 to be correctly fixed to the valve frame.

[0043] Although the illustrated hull is made of injection-molded paper material, this construction is only one example and is not limiting. In some embodiments, the hull is formed from a single piece of die-cut paper, which is folded to create a three-dimensional structure from which the rear body section and the slender front body section 210 extend. In some embodiments, this folded construction creates a polygonal cross-section in the rear body section and a polygonal cross-section in the front body section 210 (for example, octagonal and hexagonal cross-sections, respectively). To facilitate assembly, these hull embodiments include one or more grooves or guide lines that ensure correct folding.Some embodiments have a triangular, rectangular, pentagonal, hexagonal, heptagonal, octagonal shape in cross-section, or another polygonal shape in cross-section.

[0044] In some embodiments, a package sleeve can slide over the front body portion 210 and provide several important advantages. First, it provides additional structure to the recharging unit 212 by sliding over the front body portion 210 and reinforcing it. Consequently, in some embodiments, the package sleeve has a greater thickness or weight than the material that forms the shell; although this is not necessary. In some embodiments, the package sleeve is made of a recyclable material, which may be the same material as the shell. Second, the package sleeve couples to the valve frame. For example, the package sleeve may include a plurality of coupling recesses configured to couple in such a way Reversible to the valve frame coupling components. The package sleeve can facilitate the disassembly of the 212 charging unit.

[0045] In some embodiments, the valve frame provides a rigid structure that aligns the outlet nozzles 208 for proper fluid connection with the fluid lines of the formulation delivery device. Therefore, the valve frame can be made of ABS plastic, HDPE, or another rigid polymer or other material. In some embodiments, the valve frame is made of the same material as the casing. Thus, the casing, the formulation pouches, the valve frame, and an optional package sleeve form the refill unit 212. During use, the refill unit 212 can be reversibly coupled to the handle portion 202, for example, by attaching means such as coupling tabs to the casing or by a tight fit between the refill unit 212 and the handle portion 202.

[0046] As shown by way of example in [Fig. 3A], a hair clip adapter 300 is configured to be attached to and used with a formulation delivery device (for example, 104 in [Fig. 1]) to apply a cosmetic composition to a person's hair in a controllable manner. The hair clip adapter 300 comprises a movable handle 301 slidably attached to a movable arm 305 which includes a first compressible substrate 306a on it, and a fixed handle comprising a fixed arm 302 which includes a second compressible substrate 306b on it. The movable arm 305 is articulated to the fixed arm 302 by means of a hinge 305a and is slidably attached to the fixed handle 302. As shown in [Fig.3B] and [Fig.4], the fixed arm 302 and the second compressible substrate 306b each comprise a plurality of openings (i.e., the dashed lines on [Fig.3B], through which passageways of formulation 307a, 307b, 307c, 307d are formed; see also the passageways of formulation 307a, 307b, 307c and 307d in [Fig. 4]). The plurality of openings of the fixed arm 302 are configured to align with a plurality of openings of the second compressible substrate 306b to form a plurality of passageways of formulation 307a, 307b, 307c and 307d, for the passage of the cosmetic composition through them. In the embodiment shown in Figures 3A and 3B, a stress on the hair clip adapter 300, for example such as formed by a spring 303, stresses the hair clip adapter 300 towards an unclamped configuration (i.e., as illustrated in [Fig.3B]); when the stress is overcome following a compressive force applied to the movable handle 301 and / or the fixed handle 302, as occurs when a user grasps the movable handle 301 and the fixed handle 302, the hair clip adapter 300 switches to a tight configuration (i.e., . such that the compressible substrates 306a, 306b come into contact with each other and the movable handle 301 comes into contact with the fixed handle 302). In the closed configuration, which can be visually compared to a pair of scissors in a closed position, a droplet of formulation 308 comes into contact with the compressible substrate 306a (i.e., on the movable arm 305), to transfer the cosmetic composition from the compressible substrate 306b of the fixed arm 302 to the compressible substrate 306a of the movable arm 305. In this way, the cosmetic composition is distributed consistently and uniformly along the compressible substrates 306a, 306b, forming a foam to be applied evenly to the hair during a hair treatment.

[0047] In embodiments, the compressible substrates 306a, 306b may be made of materials of natural origin, such as marine sponges, or may be made of artificial materials, such as synthetic sponges or the like. The compressible substrates 306a, 306b may be permeable to water, so that aqueous cosmetic compositions can penetrate the body of the compressible substrate and be expelled, for example, through the holes in the compressible substrates, to come into uniform contact with the hair during use.

[0048] In some embodiments, the movable handle 301 is slidably attached to the movable arm 305 by means of a sliding male member 305b which is slidably engaged in an elongated opening 301a. During the movement of the movable handle 301 relative to the fixed handle 302, the sliding male member 305b slides inside the elongated opening 301a for controlled relative movement of the movable handle 301 and the movable arm 305. Furthermore, in some embodiments, the movable arm 305 is slidably attached to the fixed handle 302 by means of a sliding male member 302a which is slidably engaged in an elongated opening 305c (of the movable arm 305).The illustrated example configuration of these elements, and its equivalents, allows minimizing an angle between the compressible substrates 306a, 306b in both open (not tight) and closed (tight) configurations, so that the compressible substrates 306a, 306b come into contact with each other more uniformly.

[0049] The illustrated example configuration, and its equivalents for minimizing the angle between the compressible substrates 306a, 306b, can be compared to a typical "scissors" configuration, in which a single hinge connects two moving parts for a rigid scissor motion. For example, if a typical "scissors" configuration were used to close the compressible substrates 306a, 306b together, this could result in uneven contact between them, leading to stronger contacts at the parts of the compressible substrates near the hinge and at The expulsion of the cosmetic composition from these areas, and weaker contact at the points on the compressible substrates furthest from the hinge, can lead to the accumulation of excess cosmetic composition on these areas. This uneven distribution of the cosmetic composition could result in uneven application of the composition to the hair during a hair treatment, which could complicate the use of the clip adapter.

[0050] In the illustrated embodiment, the force is produced by a spring 303 attached to the movable handle 301 at one end thereof and attached to the fixed handle 302 at the other end thereof. The spring is forced towards a deployed configuration (for example, as illustrated in Figures 3A and 3B), to move the movable handle 301 away from the fixed handle 302 and to move the movable arm 305 away from the fixed arm 302 to form the open configuration.

[0051] In embodiments, the hair clip adapter 300 further includes a living hinge 304 which articulates a proximal portion of the movable handle 301 to a proximal portion of the fixed handle 302, and is configured to prevent contact between a part of a person's hand and a junction which includes the movable arm 301 and the fixed arm 302; in this way, the living hinge 304 can prevent or reduce the risk of injury during the use of a formulation delivery device comprising the hair clip adapter 300 which is attached thereto.

[0052] In embodiments, the fixed handle and arm 302 include a proximal fitting 302b and a distal fitting 302c that are configured to connect the hair clip adapter 300 to the formulation delivery device 400, including as illustrated by way of example in Figures 3A and 3B, 4, and 5. In embodiments, the proximal fitting 302b, the distal fitting 302c, or both, include a magnet configured for magnetic attachment of the hair clip adapter 300 to the formulation delivery device 400 by contact with one or more corresponding magnets of the formulation delivery device 400.

[0053] In embodiments, the fixed arm 302 includes a plurality of slots for spacer parts 309a, 309b, 309c, 309d, 309e, 309f, 309g, 309h configured as openings, for receiving and fixing a plurality of spacer parts 416 of the formulation delivery device 104 in them (see Figures 1, 4, and 5), for maintaining an orientation of the hair clip adapter 300 relative to an orientation of the formulation delivery device 104 during fixing and use.

[0054] In embodiments, including as illustrated by way of non-limiting example in [Fig. 4], openings of the plurality of openings of the second compressible substrate 306b are positioned between gapping slots opposite the plurality of gap slots 309a, 309b, 309c, 309d, 309e, 309f, 309g, 309h, and form a plurality of formulation passageways 307a, 307b, 307c, 307d, when aligned with a reciprocating nozzle assembly 414 of a formulation delivery device (e.g., 104 on [Fig.l]). Thus, in some embodiments, the plurality of formulation passageways 307a, 307b, 307c, 307d are positioned for a fluidic connection with the reciprocating nozzle assembly 414 for the passage of the cosmetic composition from the reciprocating nozzle assembly 414 through the plurality of formulation passageways 307a, 307b, 307c, 307d via the fluidic connection. Therefore, in some embodiments, including as illustrated in [Fig.[3B] By way of non-limiting example, the passage of the cosmetic composition (from the reciprocating nozzle assembly 414) through the plurality of formulation passageways 307a, 307b, 307c, 307d brings the cosmetic composition into contact with the second compressible substrate 306b so that it absorbs the cosmetic composition for delivery to the person's hair through the second compressible substrate 306b. This passage of the cosmetic composition through the plurality of formulation passageways 307a, 307b, 307c, 307d also causes the cosmetic composition to pass through the plurality of openings in the second compressible substrate 306b so that the cosmetic composition forms a plurality of formulation droplets 308 on the second compressible substrate 306b.

[0055] In some embodiments, the first and second compressible substrates 306a, 306b can be removed from the movable arm 305 and the fixed arm 302, respectively. In this way, the first and second compressible substrates 306a, 306b can be cleaned as part of maintenance, or discarded and replaced with new compressible substrates.

[0056] In various embodiments, with the passage of the cosmetic composition through the plurality of passageways of formulation 307a, 307b, 307c, 307d and the formation of a plurality of droplets of formulation 308 on the second compressible substrate 306b, the stress can be overcome to move the hair clip adapter towards the tight configuration so that the first compressible substrate 306a comes into uniform contact with the plurality of droplets of formulation 308 to transfer the cosmetic composition to the first compressible substrate 306a to apply the cosmetic composition uniformly to the person's hair.

[0057] In various embodiments, a formulation mixer of the formulation delivery device can be implemented in the form of a turbulent mixing chamber comprising one or more helical mixers positioned in a fluidic path, and transports, mixes, and homogenizes a mixture of formulations to produce the resulting cosmetic formulation or composition for application to hair. However, other types of formulation mixers can be implemented without departing from the scope and spirit of the disclosure. In the illustrated embodiments, the reciprocating nozzle assembly 414 comprises a plurality of nozzles (for example, spaced and separated by a plurality of spacer parts 416) and is driven by a motor, such that the plurality of nozzles move back and forth along a track while dispensing the resulting formulation; however, alternative nozzle assembly designs can be implemented without departing from the scope and spirit of the disclosure.

[0058] Moreover, in embodiments, controlling a mixing ratio between two or more formulations can advantageously contribute to various properties of the resulting cosmetic composition, such as efficacy and, consequently, the time required to apply the composition to the hair to achieve a desired effect.

[0059] Furthermore, in some embodiments, control circuitry for the formulation dispensing device 104 can be configured based on a software application, executed by at least one process of the formulation dispensing device 104 or another computing device, such as a smartphone, which defines the relative quantities of two or more formulas to be mixed for a particular hair treatment. Therefore, in some embodiments, the control circuitry is configured to receive one or more signals from one or more formulation cartridges that correspond to one or more formulations from the plurality of formulations, and to calculate the mixing ratio based on the one or more signals.Signals can be received by the circuitry via any connection to the formulation cartridges, including, but not limited to, a wired connection, or a wireless connection, such as a wireless request from a radio frequency identification (RFID) chip of a formulation cartridge, for example.

[0060] In various aspects, the disclosure proposes a formulation delivery device or formulation delivery system comprising a hair clip adapter that is attached to it or configured to be attached to it. Although an example of a formulation delivery device to which a hair clip adapter 400 is attached is shown in [Fig. 5], alternative designs and configurations that implement the hair clip adapter can be implemented without departing from the scope and spirit of the disclosure. Furthermore, although an example of a hair clip adapter 300 is shown in Figures 3A and 3B, alternative designs and configurations of the hair clip adapter 300 hairs can be implemented without deviating from the scope and spirit of the disclosure.

[0061] With further reference to [Fig. 5], a hair clip adapter 300 is shown with a cross-sectional view of an example formulation delivery device 400, representing part of a hair treatment for applying a hair care formulation to a person's hair. The formulation delivery device 400 is configured to receive a formulation cartridge type 402 (including a cleaning cartridge of the same type). An embodiment of a formulation cartridge of formulation cartridge type 402 is described herein; the formulation cartridge 402 shown in [Fig. 5] is understood to have the same characteristics as those described herein. Some embodiments of the formulation delivery device 400 include the formulation cartridge 402 and / or an optional pull adapter 104.

[0062] The formulation dispensing device 400 includes a reusable handle formed from ABS plastic or a similar rigid polymer or other material and, in some embodiments, is an assembly formed from a plurality of shells configured to be joined together using fasteners, such as snap fasteners, screws, or the like. The reusable handle has a hollow, elongated gripping portion enclosing a cartridge cavity that is shaped and sized to receive the formulation cartridge type 402. In some embodiments, the cavity includes hooks that facilitate the correct insertion of the formulation cartridge type 402.For example, embodiments include a cartridge interface 408 disposed in the opening and having a flat receiving surface which interfaces with a corresponding receiving surface of the formulation cartridge 402 when the latter is correctly inserted into the opening.

[0063] The formulation dispensing assembly 410 dispenses a formulation or cleaning liquid from the formulation cartridge 402 and includes a pump, fluid lines, a mixing chamber, and a reciprocating nozzle assembly 414 having nozzles that extend from the front end of the reusable handle between a plurality of optional spacer portions (e.g., 416 in [Fig. 1]). As shown in [Fig. 5], the reciprocating nozzle assembly includes a plurality of ring nozzles that perform a back-and-forth reciprocating motion along a track of the reusable handle while dispensing the formulation onto a user's skin or hair. In some embodiments, the reciprocating nozzle assembly performs a reciprocating motion at a reciprocating motion amplitude of approximately 7.0 to 12.0 mm (for example, 8.0 mm to 11.0 mm or 9.0 to 10.0 mm) and / or at a motion frequency alternative of about 5.0 Hz to 10.0 Hz (e.g., 6.0 Hz to 9.0 Hz, 6.0 Hz to 8.0 Hz), which are adjustable by the formulation routine module, the cleaning routine module, the user routine module, the manual adjustment module or another module (e.g., one or more modules or process steps of a software application).

[0064] In some embodiments, the reusable handle also houses several subassemblies, including a control device 412, which includes a processor and a data store storing several modules (for example, circuitry configured for logic operations and / or processes), a cartridge authentication interface 430, a power supply, a formulation dispensing assembly 410, and an optional position sensor. The formulation stored in the formulation container(s) 418 can be dispensed and mixed inside the formulation dispensing device 400 for contact with the compressible substrates 306a, 306b and application to the person's hair.Thus, the formulation cartridge 402 comprises one or more formulation containers 418 (for example, pouches or packets) arranged therein, each of them having an outlet nozzle 420 protruding through a distal (forward) end of the formulation cartridge 402 in a configuration that fluidically connects to a corresponding formulation inlet 422 of the formulation dispensing assembly 410 when the formulation cartridge 402 is fully inserted into the cartridge cavity.

[0065] In some embodiments, a button 426 located on the reusable handle and electrically connected to the control device 412 activates the functions of the formulation dispensing device 400. In some embodiments, pressing the button 426 activates a sleep / wake module stored in the control device 412, thereby switching the formulation dispensing device 400 from a sleep state to a wake state. In some embodiments, pressing the button 426 while a formulation cartridge is inserted into the reusable handle activates a formulation routine module stored in the control device 412, thereby initiating a formulation routine.

[0066] In some embodiments, pressing the button 426 while a cleaning cartridge is inserted into the reusable handle activates a cleaning routine module stored in the control device 412, thereby initiating a cleaning routine. Visual indicators 428 (for example, LEDs) arranged along the reusable handle indicate one or more pieces of information, such as the amount of formulation remaining or the remaining battery life, for example, based on a dispensing time determined by the formulation routine module of the control device. Some embodiments include buttons additional and / or a different number of visual indicators 428 with different functionalities, and the illustrated embodiment is not limiting. In some embodiments, the visual indicator 428 is a multi-segment LED, each segment corresponding to an equal proportion of the formulation remaining in the formulation cartridge.

[0067] The control device 412 includes logic (stored in one of its data stores) which, when executed by a processor of the control device 412, causes a cartridge authentication interface 430 disposed in the reusable handle (for example, 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 piece of information from among a formulation cartridge 402, a formulation identification, an initial quantity of formulation, a formulation expiration date or a formulation production date.

[0068] The control device 412 also includes logic which, when executed, causes the formulation delivery system to execute, on the basis of the authentication of the formulation cartridge 402, a formulation routine which distributes a mixture of formulations (of the first formulation and the second formulation) from the formulation cartridge 402 via the formulation distribution assembly.For example, the formulation delivery device authenticates the first and second formulations after (or during) the insertion of a formulation cartridge into the reusable handle, then in response to the pressing of a button on the reusable handle, executes a formulation program which causes the formulation dispensing assembly 410 to continuously or continuously mix the first and second formulations, and dispense them from the reciprocating nozzle assembly at one or more of the following predetermined device operating parameters as long as the button is pressed: a formulation flow rate, a reciprocating frequency, or a reciprocating amplitude.

[0069] In some embodiments, the control device 412 also includes logic which, when executed, causes the formulation dispensing device to perform, based on the authentication of 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 dispensing device authenticates a cleaning cartridge inserted into the reusable handle, and then, in response to a button being pressed on the reusable handle, performs a cleaning routine that causes the formulation dispensing assembly to continuously dispense a liquid. Cleaning (for example, with water) from the reciprocating nozzle assembly is performed at one or more of the following predetermined device operating parameters as long as the button is pressed: a cleaning fluid flow rate, a reciprocating motion frequency, or a reciprocating motion amplitude. In some embodiments, the cleaning fluid flow rate is greater than any formulation flow rate of one or more formulation routines stored in the control device 412, in order to efficiently rinse residual formulation from the formulation dispensing assembly.
