[0022] The preceding aspects and many related advantages of the present invention will be more readily appreciated as they are better understood with reference to the following detailed description, when taken in conjunction with the accompanying drawings. Detailed description

[0023] Devices, systems, and methods configured for degassing formulation cartridges are disclosed herein. In some embodiments, a device configured for selectively applying hair dye and developer is disclosed herein. Hair developer, when mixed with hair dye and left in a formulation cartridge or other container, can release gas. When a user attempts to apply the hair dye and / or developer with a device, the ratio of hair dye to developer may be altered or incorrect because the formulation cartridge containing the developer releases gas, while the formulation cartridge containing the hair dye dispenses hair dye. Accordingly, examples of release mechanisms and internal protrusions for degassing hair developer formulation cartridges to avoid this problem are disclosed herein.Although the following disclosure mentions hair developer, it should be understood that any formulation that releases gas could be used with the devices, systems, and processes described herein, including, but not limited to, hair dyes, cosmetic formulations, nail polishes, and the like.

[0024] Figure 1 is an example of a device according to the present technology. A representative formulation delivery device 100 and its components are shown according to an embodiment of this disclosure. The formulation delivery device 100 is configured to receive a formulation cartridge type 102 (including a cleaning cartridge of the same type). An embodiment of a formulation cartridge of formulation cartridge type 102 is described in detail below with reference to Figures 2A-4D; the formulation cartridge 102 shown in Figure 1 is understood to have the same features as those described herein. Some embodiments of the formulation delivery device 100 include the formulation cartridge 102 and / or an optional traction adapter 104.

[0025] The formulation delivery device 100 includes a reusable handle 106 formed from ABS plastic or a similar rigid polymer or other material, and in some embodiments, it is an assembly formed from a plurality of shells configured to be joined together using fastening elements such as snap fasteners, screws or the like. The The reusable handle 106 includes a hollow, elongated gripping portion containing a cartridge cavity within it, which is shaped and dimensioned to receive the formulation cartridge type 102. In some embodiments, the cavity includes hooking features that facilitate the correct insertion of the formulation cartridge type 102. For example, some embodiments include a cartridge interface 108 disposed in the opening and having a flat receiving surface that interfaces with a corresponding receiving surface of the formulation cartridge 102 when the latter is correctly inserted into the opening.

[0026] A control device (not shown in [Fig. 1]) includes logic configured to operate on a machine-readable, non-transient storage medium and includes modules that personalize the user experience, provide useful analytics, and enable e-commerce. In some embodiments, a corresponding application runs on a mobile device such as a smartphone, tablet, or similar device and interacts with a user (e.g., an end user or a salon technician) to provide actionable information through a plurality of modules. In some embodiments, the application communicates with the formulation dispensing device 104 and a network, such as a mobile network, a cloud-based enterprise network, a local area network, or similar devices.

[0027] Together, the formulation cartridge 102, the formulation dispensing device 104, and the application provide an enhanced and personalized user experience. In some embodiments, the formulation dispensing device 104 is a connected electromechanical device that interacts with the user, with formulation cartridges 102, and optionally with the application to provide a personalized user experience.

[0028] Generally, the formulation delivery device 104 includes a reusable handle 106 configured to receive the formulation cartridge type 102, as well as a formulation dispensing assembly and a control device, both disposed within the reusable handle. The formulation dispensing assembly includes at least one fluid conduit fluidically connected to a motorized pump and a reciprocating nozzle assembly, and is configured to draw the formulation and cleaning fluid from the formulation cartridge 110 and to dispense them via the reciprocating nozzle assembly onto a section of hair, scalp, or body of a user.

[0029] The control device is configured to switch between at least one cleaning routine and one formulation routine in response to one or more inputs indicative of the cleaning cartridge or formulation cartridge 102 inserted into the reusable handle 106.

[0030] In some embodiments, the formula dispensing device 104 further includes a cartridge interface 108 configured to accept the formula cartridge 102, a reciprocating nozzle assembly 114 configured to move a plurality of nozzles or spacing protrusions 116, a button 126 for actuating the formula dispensing device 104, visual indicators 128 (such as light-emitting diodes (LEDs)) indicating a status of the formula dispensing device 104, a cartridge cavity 124 configured to accept the formula cartridge 102 and an encryption chip 132.

[0031] Figures 2A-2B are examples of formulation cartridges according to the present technology. A formulation cartridge 102 is shown, representative of a formulation cartridge type that is compatible with any of the formulation delivery systems, formulation delivery devices, and formulation product lines described in this document. However, the formulation delivery systems, formulation delivery devices, and formulation product lines described in this document are not required to use the durable formulation cartridge 102 shown in Figures 8A-10.

[0032] The formulation cartridge 102 is a sustainable embodiment specifically designed to reduce waste and environmental impact, while offering a user-friendly experience. To this end, the formulation cartridge 102 includes two main components: a handle portion 205 and a disposable formulation cartridge refill unit 201 (hereinafter simply referred to as the refill unit 201) configured to slide reversibly into the handle portion 205. Historically, known cartridges were designed to be entirely discarded after the stored formulation within them was exhausted, resulting in significant waste and higher consumption costs.

[0033] Unlike known cartridges, the formulation cartridge 102 is constructed so that the handle portion 205 can be reused indefinitely and the refill units 201 can be easily replaced once the stored formulation within them is exhausted. Furthermore, each refill unit 201 is designed to be broken down into smaller components, some of which can be recycled in certain embodiments, and others disposed of. Thus, the formulation cartridge 102 uses an innovative structure to reduce waste and improve the user experience.

[0034] The handle part 205 is cut, dimensioned and constructed to be repeatedly inserted into the cartridge cavity of the formulation delivery device. Therefore, the handle portion 205 is formed of ABS plastic or a similar rigid polymer or other material and includes a hollow handle portion 205 configured to receive the refill unit 201 and a tray portion 219 extending away from the handle portion 205. The handle portion 205 is a two-piece assembly in the representative embodiment shown (although it may be a single piece in other embodiments), and is cut and dimensioned so that it forms a seamless extension of the formulation delivery device handle when fully inserted into a cartridge cavity (such as the cartridge cavity 124) thereof. The tray portion 219 projects away from the handle portion 205 and has a U-shaped configuration to support the refill unit 201 (for example, the front body portion 209).To facilitate secure insertion and easy removal, the handle portion 205 includes coupling means for coupling the formulation cartridge 102 to a reusable handle of a formulation dispensing device. Representative coupling means include a cartridge release mechanism 221 (for example, a latch) formed in the handle portion 205, which engages with the formulation dispensing device once correctly and fully inserted. Thus, the common formulation cartridge type 110 allows the consumer to use many different formulations in a single formulation dispensing device 104.

[0035] In a representative embodiment, the formulation product line 102 includes a hair coloring formulation and a scalp treatment formulation. In other representative embodiments, the formulation product line 102 comprises at least two, three, four, five, six, seven, or eight of the following different formulations, each stored in the same type of formulation cartridge 110: a permanent hair dye and developer; a semi-permanent hair dye and developer; a shampoo; a conditioner; a hair growth treatment, such as minoxidil; a protein hair treatment; a disulfide bond repairing hair treatment; or a fluid scalp treatment.

[0036] Figure 3 is an exploded view of an example of a formula cartridge according to the present technology. In some embodiments, the refill unit 201 generally includes a refill pack comprising a shell 207 containing at least one formulation container (e.g., a pack, a sachet, or other container), for example, a first formulation sachet 243A and a second formulation sachet 243B, as well as a valve frame 213 coupled to the refill pack, for example, a body portion 209 of the shell 207. The first formulation sachet 243A and the second formulation sachet 243B contain, respectively, a first formulation and a second formulation. The 201 refill unit may optionally include a 241 pack sleeve.

[0037] Each of the first formulation sachet 243A and the second formulation sachet 243B has 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 formulation sachet 243A and the second formulation sachet 243B have different volumes. In some embodiments, the refill unit 201 stores only one formulation container.

[0038] The first and second formulations can be any of the formulations described herein, for example, a permanent hair dye; a semi-permanent hair dye; a developer; a conditioner; a hair growth treatment, such as minoxidil; a protein hair treatment; a disulfide bond repairing hair treatment; a fluid hair treatment; a fluid scalp treatment, or the like. In some embodiments, the first and second formulations differ. For example, in some embodiments, the first formulation is a hair dye and the second formulation is a developer. In other embodiments, the first and second formulations are the same (for example, a conditioner or a scalp treatment formulation).

[0039] As shown in [Fig. 3], each formulation sachet 243A, 243B comprises a packet containing a formulation 247 and a valve-forming means for the selective fluidic coupling of the refill unit to a dispensing nozzle unit of a formulation delivery device when the formulation cartridge 102 is received within the hand-held formulation dispensing device. Representative valve-forming means include a valve 215 through which the formulation exits the packet 247. Representative formulation containers are described in International Patent Application Publication No. 2019 / 067336A2, published April 4, 2019, and US Patent Application Publication No. 2021 / 0196021A1, published July 1, 2021.

[0040] The shell 207 has an elongated shape designed to fit within the reusable handle portion 205. The shell 207 encloses and protects the first formulation sachet 243A and the second formulation sachet 243B and engages with the valve frame 213 (described below). Thus, the shell 207 functions as packaging that protects the formulation sachets 243A and 243B during transport before loading into the formulation dispensing device.

[0041] In some embodiments, the shell 207 has an overall length of between 150 mm and 250 mm (for example, 175 mm–225 mm, 185 mm–215 mm, 195 mm–205 mm, or 200 mm) and a maximum cross-sectional dimension of 25 mm–50 mm (for example, 30 mm–45 mm, 35 mm–40 mm, or 36 mm). The shell 207 has a rear body portion 225 and a slender front body portion 209, for example, a neck portion, extending away from the body portion 225. The body portion 225 and the slender front body portion 209 are generally aligned in a common longitudinal direction to allow assembly with the reusable handle portion 205 and to allow insertion into the cartridge cavity of the formulation delivery device.

[0042] In some embodiments, the shell 207 is constructed at least partially from a recyclable or recycled material, for example, a paper material such as injection-molded paper or die-cut textured paper (e.g., cardboard). In the illustrated embodiment, the shell 207 is formed from a single piece of injection-molded paper material. In some embodiments in which the shell 207 is formed from paper, the paper has a weight between 8 and 12 points (e.g., 8.5 points, 9.0 points, 9.5 points, 10.0 points, 10.5 points, 11.0 points, or 11.5 points) to provide sufficient stiffness without contributing to an excess of disposable material.

[0043] The rear body portion 225 of the casing 207 has a larger cross-sectional area than the front body portion 209 when viewed in a plane perpendicular to the longitudinal direction of the cartridge 102. A bump or bulge 227 provides the larger cross-sectional area of ​​the rear body portion 225 relative to the slender front body portion 209. Advantageously, the bump or bulge 227 allows the use of larger-volume formulation sachets 243A, 243B. In addition, the bump or bulge 227 forms a stop 231 that bears against a corresponding inner face of the handle portion 205 and secures the longitudinal position of the casing 207 during use.

[0044] The slender front body portion 209 of the shell 207 is shaped to fit within the tray portion 219 of the handle portion 205 and to protrude into the cartridge cavity of the formulation delivery device during use. In some embodiments, the front body portion 209 is coupled to the valve frame 213. To facilitate secure connection and alignment with the valve frame 213, the front body portion 209 includes valve frame coupling means, for example, at least one coupling tab 237 configured to selectively engage with the valve frame 213. In the illustrated embodiment, the front body portion 209 includes a single coupling tab 237 extending away from one of its front ends. The coupling tab 237 includes an engagement feature, by example a notch or raised prominence 239 shaped and cut to engage with a complementary opening 251 of the valve frame 213.

[0045] The body portion 209 can have many different configurations. For example, the illustrated shell portion 209 is a double-shell configuration formed of at least two partial shells (in this embodiment, two halves 229A, 229B) coupled by a hinge, for example, a hinge formed as a single unit with the two halves. In some embodiments, the shell 219 includes a different number of partial shells, for example, three or four partial shells that come together to enclose the formulation sachets 243A, 243B. Alignment of the halves 229A, 229B allows the front body portion 209 to be properly attached to the valve frame 213.

[0046] Although the illustrated body 207 is formed from an injection-molded paper material, this construction is representative, not limiting. In some embodiments, the shell 207 is formed from a single piece of die-cut paper, which is folded to give a three-dimensional structure from which the rear body portion 225 and the slender neck portion 209 extend. In some of these embodiments, this folded construction creates a polygonal cut in the rear body portion 225 and a polygonal cut in the front body portion 209 (for example, octagonal and hexagonal cuts, respectively). To facilitate assembly, some of these embodiments of the shell 207 include one or more grooves or guide lines that ensure correct folding. Some embodiments have a triangular, rectangular, pentagonal, hexagonal, heptagonal, octagonal, or other polygonal cross-sectional shape.

[0047] An optional package sleeve 241 slides onto the neck portion 209 and offers several important advantages. First, it provides additional structure to the charging unit 201 by sliding onto the front body portion 209 and reinforcing it. Consequently, in some embodiments, the package sleeve 241 has a greater thickness or weight than the material that forms the shell 207; although this is not necessary. In some embodiments, the package sleeve 241 is also made of a recyclable material, which may be the same material as the shell 207.

[0048] Secondly, in some embodiments, the package sleeve 241 couples to the valve frame 213. For example, the illustrated package sleeve 241 includes a plurality of engagement member recesses 235 configured to couple reversibly with engagement members of the valve frame 213.

[0049] Third, the package sleeve 241 facilitates the disassembly of the refill unit 201. In some embodiments, the package sleeve 241 includes an optional integral tear strip 235A formed on it (for example, a perforation with a pull tab). In other embodiments, the tear strip is formed on the neck portion 209 (see tear strip 235B). During use, after the formulation packets 243A, 243B have been exhausted, the user pulls the pull tab of the integral tear strip 235A and / or 235B, thus separating the valve frame 213 from the packet sleeve 241. Once this action is complete, the packet sleeve 241 is recycled and the valve frame 213 is discarded. In some embodiments, the integral tear strip 836 is positioned on the shell 207, for example, the front body portion 209.

[0050] The valve frame 213 provides a rigid structure that aligns the formulation sachet valves 215 for proper fluid connection with the fluid lines of the formulation dispensing device. Furthermore, in some embodiments, the valve frame 213 supports an optional encryption chip 211 as described above. In such embodiments, the valve frame 213 is machined and formed to precisely position the encryption chip 211 adjacent to the cartridge authentication interface of the formulation dispensing device when the formulation cartridge 102 is disposed in the handle of the formulation dispensing device. Therefore, the valve frame 213 is formed from ABS plastic, HDPE, or other rigid polymer or other material. In some embodiments, the valve frame 213 is formed from the same material as the shell 219.

[0051] A plurality of valve engagement units 217 extend through a front end of the valve frame 213. Each valve engagement unit 217 receives and secures one of the formulation sachet valves 215. In some embodiments, the valve engagement unit 217 is a valve opening or cutout disposed through a face of the valve frame 213, the valve opening or cutout being shaped to receive a valve from a formulation sachet and optionally to engage with an outer circumference of the valve. To allow coupling with the package sleeve 241 (or the shell 207 in some embodiments), the valve frame 213 includes optional engagement members 249 (for example, tabs) extending from it. In some embodiments, the valve frame 213 engages with the front body portion 209 by a tight fit.

[0052] The encryption chip 211 (for example, an RFID tag) is disposed on the refill unit 201, for example, on the body part 207 or on the valve frame 213 (as in the illustrated embodiment). The encryption chip 211 is positioned on the refill unit 201 so that when the formulation cartridge 102 is inserted into the formulation dispensing device, it is positioned to be read by the cartridge authentication interface of the latter. Therefore, the encryption chip 211 stores information about the formulation cartridge 102 and its contents, for example, at least one piece of information from a formulation identification, an initial formulation quantity, a formulation expiration date, or a formulation production date.

[0053] Thus, the body 207, the formulation sachets 243A, 243B, the valve frame 213 and an optional package sleeve 241 form the refill unit 201. During use, the refill unit 201 can be reversibly coupled with the handle part 205, for example, by fastening means such as coupling tabs on the shell 207 or by tight fit between the refill unit 201 and the handle part 205.

[0054] Figures 4A-4D show examples of release mechanisms for a Formula 102 cartridge according to the present technology. In some embodiments, due to the nature of the hair developer formula (which may be the first formulation, the second formulation, or both as described herein), the Formula 102 cartridge may need to be degassed. Hair developers may contain oxidizing agents that can release fumes when mixed with hair color formulas. When small amounts of the hair developer and hair dye are mixed and left to stand, for example, after a user has applied the hair dye and the hair developer, gas may be released. Furthermore, if the hair developer is left inside the Formula 102 cartridge, gas may accumulate inside the Formula 102 cartridge.

[0055] Therefore, in some embodiments, the formula cartridge 102 may include a bump or bulge 227, made up of halves 229A, 229B and two valves 215A, 215B. A release mechanism 223 is disposed on the bump 227.

[0056] During operation, as shown in [Fig. 4B], when the release mechanism 223 is pressed, depressed, lifted, opened, brought into contact, or otherwise manipulated, the gas G created by the hair developer can be degassed. In this way, a user or a device (such as device 100) can release the gas G from the formula cartridge 223 either on demand or periodically, to avoid expelling the gas G from the device during an attempt to apply the hair developer. Failure to degas the formula cartridge 102 could result in the gas G being dispensed from the hair developer formula cartridge 102, while the hair dye could be dispensed from another formula cartridge (as shown in [Fig. 3]).This can lead to a change in the ratio between the hair developer and the hair dye, which could reduce the effectiveness of the hair dye, create unwanted marks in the user's hair, or similar issues. Therefore, the 223 release mechanism ensures that the G gas is not released. by the formula 102 cartridge when the user attempts to apply the hair developer (or any formulation that may release gas) and ensures that the ratio between the hair developer and the hair dye is correct.

[0057] In some embodiments, the release mechanism 223 may be located on the lower half 229B of the formula cartridge 102, as shown in [Fig. 4C]. In still other embodiments, the release mechanism 223 may be located on a rear portion (or bottom) 225 of the formula cartridge 102, as shown in [Fig. 4D]. Although Figures 4A-4D show representative locations of the release mechanism 223, it should be understood that the release mechanism 223 may be located anywhere on the formula cartridge 102. Furthermore, in some embodiments, multiple release mechanisms 223 may be located on the formula cartridge 102.

[0058] The release mechanism 223 is illustrated as having a semi-oval shape, but it should be understood that the release mechanism 223 can have any shape. In some embodiments, the release mechanism 223 is configured to open outwards, as shown in [Fig. 4B]. In other embodiments, the release mechanism 223 is configured to open inwards, as shown in [Fig. 5C]. In some embodiments, the release mechanism 223 can be configured to pivot both inwards and outwards.

[0059] Figures 5A to 5G are process diagrams for degassing a formula cartridge according to the present technology. In some embodiments, the handle portion 205 of the formula cartridge 102 includes a protrusion 300, internal to the handle portion 205, as shown in Figures 5A-5C. In some embodiments, the handle portion 205 is configured to retain and / or surround the body portion 227.

[0060] In some embodiments, the protrusion 300 is configured to apply pressure to the release mechanism 223 when the body part 227 is inserted into the handle part 205. In some embodiments, the pressure degasses the body part 227 of the formulation pouch, for example, by expelling gas G as shown in [Fig. 5C]. In some embodiments, when the body part 227 is held in the handle 205, the protrusion 300 is in contact with the release mechanism 223, i.e., the release mechanism 223 is always suppressed and capable of expelling gas G from the formulation cartridge. In other embodiments, the protrusion 300 may be in contact with the release mechanism 223 only while the formulation cartridge is inserted into the handle 205.That is to say, the release mechanism 223 can only be pressed for a moment when the formula cartridge is inserted into. the handle 205, and when the formula cartridge is completely retained in the handle 205, the release mechanism 223 can be closed.

[0061] In some embodiments, the protrusion 300 may be triangular. In some embodiments, the protrusion 300 is located on one side of the handle 205 (as shown in Figures 5A-5C). In some embodiments, the protrusion 300 may be located on the bottom of the handle 205, as shown in [Fig. 6C].

[0062] In certain embodiments, when the release mechanism 223 is brought into contact or pressed by the protrusion 300, an opening O is formed in the body part 227 of the formula cartridge.

[0063] In some embodiments, the formula cartridge includes one or more valves (such as valve 215 and / or valves 215A, 215B) configured to purge the G gas emitted by the release mechanism 223.

[0064] Figures 6A-6D are examples of handle parts according to the present technology. The protrusion 300 (as shown in Figures 5A-5C) can take any number of shapes. Representative protrusions are illustrated in Figures 6A-6D.

[0065] In some embodiments, the protrusion is a bump 301, as shown in [Fig. 6A]. In some embodiments, the bump 301 may be located on a first side (or "first inner side") S1 of the handle 205. Those skilled in the art will recognize that in other embodiments, the bump 301 may be located on a second side (or "second inner side") S2 of the handle 205.

[0066] In some embodiments, the protrusion is a spring 310, as shown in [Fig. 6B]. While the spring 310 is located on a first inner side S1 of the handle 205, it should be understood that the spring 310 can be located on the second inner side S2. In some embodiments, the spring 310 includes a coil 302 and a platform 303. In some embodiments, the spring 310 includes only a coil 302. In some embodiments, the spring 310 is selected from a compression spring, a leaf spring, or a molded spring.

[0067] In some embodiments, as shown in [Fig. 3], the formulation cartridge includes a valve (such as valve 215, valves 215A, 215B, or a combination thereof) configured to vent the emitted gas from a release mechanism (such as release mechanism 223). In some embodiments, the valve is force-balanced with respect to spring 310.
