- the following description provides several examples that relate generally to hair and scalp treatment applicators and formulation delivery appliances.
- Application of a wide variety of treatment formulations to human hair and scalp tissue is a common practice.
- applying a treatment formulation to a portion of the hair near the scalp may be desired, for instance, when applying a coloring dye to roots of hair during a color maintenance procedure.
- applying a treatment formulation directly to the scalp tissue, while minimizing contact with the hair may be desired.
- Hair coloring formulation typically includes at least one dye and a separate developer, which must be mixed in controlled proportions for effective and predictable results.
- the term “coloring formulation” refers generally to any of the dye, developer, formulation, fluid, or any mixture thereof.
- formulations include: permanent hair dye; semi-permanent hair dye; developer; conditioner; hair growth treatment, such as minoxidil manufactured under the trade name ROGAINE®; hair protein treatment; disulfide bond repairing hair treatment, such as OLAPLEX®; fluid hair treatment; fluid scalp treatment, and the like.
- any hair and scalp treatment formulation is contemplated herein, the present disclosure generally refers to hair coloring formulation as the exemplary formulation. However, it should be appreciated that any of the listed hair and scalp treatment formulations are interchangeable with the coloring formulation described herein.
- Systems for the application of hair and scalp treatment formulations may utilize one or more cartridges that store formulation.
- Representative systems for the application of hair and scalp treatment formulations include those disclosed in U.S. patent application Ser. Nos. 15/721,659, 15/721,668, 15/721,678, and 15/721,682, each of which is herein incorporated by reference in its entirety.
- Such cartridges may be transported through a supply chain, for example in boxes containing a supply of refill cartridges.
- supply chains may present a number of environmental challenges to the cartridges, including varying temperatures, physical shocks, and prolonged periods without movement (during which time components of the formulation could settle and separate).
- components of the formulation e.g., the dye and developer
- a formulation may have a limited useful lifespan after the components are mixed, for example, due to oxidization.
- the cartridges reliably keep components of the formulation separated until a user purposefully mixes the components.
- the mixing process occurs entirely within the cartridge in order to ensure quick and accurate mixing, with no mess and no oxidization.
- the cartridges may be modular and consumable, for reduced cost and increased convenience.
- a representative and non-limiting cartridge 20 includes a pouch 24 having an outlet 28 , and a fitment 32 sealed within the outlet 28 .

Description
- This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This summary is not intended to identify key features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
- In an aspect, a cartridge configured for use in a hair treatment device includes a pouch having an outlet, a capsule located within the pouch, and a fitment sealed within the outlet of the pouch. The pouch may contain a first product and the capsule may contain a second product. In an embodiment, the first product may be a colorant and/or the second product may be a developer. In an embodiment, the cartridge may include a filter affixed to the fitment, and/or the pouch may be lined with polypropylene and heat sealed to the fitment. In an embodiment, at least one of the first product or the second product may be liquid. In an embodiment, at least one of the first product or the second product may be cream. In an embodiment, at least a portion of the pouch may be gas-permeable and liquid impermeable. In an embodiment, the cartridge may include a second capsule located within the pouch that contains a third product. The second capsule may have a different shape and/or surface texture than the capsule. In an embodiment, the first product may have a first volume and the second product may have a second volume. The ratio of the first volume to the second volume may be between 0.1 to 10.0, inclusive. In an embodiment, the capsule may be frangible or may have a flexible membrane. In an embodiment, the pouch may contain a mixing element.
- In another aspect, a method of using a cartridge configured for use in a hair treatment device includes providing a cartridge having a pouch, breaking a capsule located in the pouch, and shaking the cartridge. The pouch may have a fitment sealed within an outlet and may contain a first product. The capsule may contain a second product. In an embodiment, breaking the capsule may include using a component of the hair treatment device. In an embodiment, breaking the capsule may include inserting the capsule into the hair treatment device.
- In another aspect, a hair treatment system for applying a formulation includes a hair treatment device and a cartridge configured for installation in the hair treatment device. The cartridge may include a pouch having an outlet, a capsule located within the pouch, and a fitment sealed within an outlet of the pouch. The pouch may store a first product and the capsule may store a second product.
- The foregoing aspects and many of the attendant advantages of disclosed subject matter 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. It shall be appreciated that the figures below are not necessarily to scale, and are intended to facilitate understanding of the inventive concepts discussed herein:
-
FIG. 1 is an isometric view of a cartridge formed in accordance with a representative embodiment of the present disclosure. -
FIG. 2 is an isometric view of the cartridge ofFIG. 1 , shown with certain surfaces hidden. -
FIG. 3 is an exploded partial isometric view of the cartridge ofFIG. 1 . -
FIG. 4 is an isometric partial view of the cartridge ofFIG. 1 . -
FIG. 5 is an isometric view of another cartridge formed in accordance with a representative embodiment of the present disclosure, shown with certain surfaces hidden. - The following description provides several examples that relate generally to hair and scalp treatment applicators and formulation delivery appliances. Application of a wide variety of treatment formulations to human hair and scalp tissue is a common practice. In some instances, it is beneficial for the treatment formulation to be applied to a targeted portion of the hair or scalp tissue. In one example, applying a treatment formulation to a portion of the hair near the scalp may be desired, for instance, when applying a coloring dye to roots of hair during a color maintenance procedure. In another example, applying a treatment formulation directly to the scalp tissue, while minimizing contact with the hair, may be desired.
- Hair coloring formulation typically includes at least one dye and a separate developer, which must be mixed in controlled proportions for effective and predictable results. As used herein, the term “coloring formulation” refers generally to any of the dye, developer, formulation, fluid, or any mixture thereof. Examples of formulations include: permanent hair dye; semi-permanent hair dye; developer; conditioner; hair growth treatment, such as minoxidil manufactured under the trade name ROGAINE®; hair protein treatment; disulfide bond repairing hair treatment, such as OLAPLEX®; fluid hair treatment; fluid scalp treatment, and the like. Although any hair and scalp treatment formulation is contemplated herein, the present disclosure generally refers to hair coloring formulation as the exemplary formulation. However, it should be appreciated that any of the listed hair and scalp treatment formulations are interchangeable with the coloring formulation described herein.
- Systems for the application of hair and scalp treatment formulations may utilize one or more cartridges that store formulation. Representative systems for the application of hair and scalp treatment formulations include those disclosed in U.S. patent application Ser. Nos. 15/721,659, 15/721,668, 15/721,678, and 15/721,682, each of which is herein incorporated by reference in its entirety. Such cartridges may be transported through a supply chain, for example in boxes containing a supply of refill cartridges. Such supply chains may present a number of environmental challenges to the cartridges, including varying temperatures, physical shocks, and prolonged periods without movement (during which time components of the formulation could settle and separate). For at least these reasons, it may be desirable to keep components of the formulation (e.g., the dye and developer) separated within the cartridge for a period of time, e.g., until shortly before use. When it is time to combine components of the formulation, those components must ordinarily be mixed in controlled proportions and mixed uniformly for effective and predictable results. Additionally, a formulation may have a limited useful lifespan after the components are mixed, for example, due to oxidization.
- The following discussion provides cartridges, systems, and methods that address the foregoing challenges. The cartridges reliably keep components of the formulation separated until a user purposefully mixes the components. The mixing process occurs entirely within the cartridge in order to ensure quick and accurate mixing, with no mess and no oxidization. The cartridges may be modular and consumable, for reduced cost and increased convenience.
- Referring to
FIGS. 1-4 , a representative andnon-limiting cartridge 20 includes apouch 24 having anoutlet 28, and afitment 32 sealed within theoutlet 28. - As shown in
FIGS. 1-3 , thepouch 24 has an elongate and relatively flat, rectangular shape. Thepouch 24 has afirst side 36 and asecond side 40. Some embodiments may have a different shape, such as a square or round shape. Some embodiments are not relatively flat, but may have a thickness that approaches or exceeds other dimensions. Thefirst side 36 and thesecond side 40 of thepouch 24 may be mutually sealed around one or more edges. For example, referring toFIG. 1 , the first andsecond sides pouch 24 are sealed along afirst edge 52, asecond edge 56, athird edge 60, and along a portion of afourth edge 64. - Referring to
FIGS. 1 and 2 together, the first andsecond sides pouch 24 may define a cavity 68 therebetween in areas where the first andsecond sides more capsules 76, mixing elements (e.g., a bead, beater, or magnet), and potentially other items as described below. As used herein, the term “product” may refer to a liquid, a cream, a solid (e.g., a powder), or another type of product. - One or more edges of the
pouch 24 may not be completely sealed, thereby leaving the first andsecond sides outlet 28 through which contents contained within the cavity 68 may exit thepouch 24. In thepouch 24 ofFIGS. 1-4 , theoutlet 28 is formed between the first andsecond sides fourth edge 64. - The
pouch 24 may be formed from one or more relatively flexible materials, such as a metallic foil (e.g., an aluminum foil) or a thin polymer (such as polypropylene). The first andsecond sides pouch 24 ofFIGS. 1-4 each include anouter layer 80 and aninner layer 84. Theouter layer 84 is formed from a metallic foil (to prevent light from entering the cavity and to prevent oxidation) and theinner layer 84 is formed from polypropylene to prevent chemical reactions between theouter layer 80 and contents contained within the cavity 68. In some embodiments, one or more of the materials forming thepouch 24 may have a laminated structure with a plurality of layers of similar or dissimilar materials. For example, one or more of the materials forming thepouch 24 may be gas-permeable, e.g., to relieve pressure within thepouch 24 that may otherwise be caused by off-gassing of contents contained within thepouch 24. - Additionally or alternatively, one or more of the materials forming the
pouch 24 may be liquid-impermeable, e.g., to securely contain liquid contents within the pouch without leakage. One or more of the materials forming thepouch 24 may be both gas-permeable and liquid impermeable. One or more of the materials forming thepouch 24 may be opaque or impenetrable to light. Thepouch 24 may have some rigidity, but may generally deform and deflect in response to an applied force. - As noted above, the
cartridge 20 includes afitment 32 that enables contents contained within thepouch 24 to exit thecartridge 20 in certain circumstances. To ensure a liquid-tight fit with thepouch 24, thefitment 32 may be sealed within theoutlet 28 of the pouch. Thefitment 32 ofFIGS. 1-4 is heat-sealed within theoutlet 28. In some embodiments, thefitment 32 may be sealed within theoutlet 28 using one or more of an adhesive, a mechanical fastener, a gasket, or other sealing means. Thefitment 32 may be formed from one or more materials selected to prevent undesirable chemical reactions with products contained within thecartridge 20. For example, thefitment 32 ofFIGS. 1-4 is substantially formed from polypropylene. As shown inFIG. 4 , thefitment 32 includes anorifice 88 that establishes fluid communication between the cavity 68 and the surrounding environment, thereby enabling products contained within thepouch 24 to exit thecartridge 20. Theorifice 88 may include a penetrable membrane, a valve (e.g., a check valve), and/or other structure that may selectively allow contents contained within thepouch 24 to exit, such as when thecartridge 20 is loaded into a device for dispensing formulation. The fitment may also include engagement structure that is configured to engage a device for dispensing formulation. For example, the fitment ofFIGS. 1-4 includes a plurality of annular flanges that radially surround the outlet. These flanges may engage complementary structure in a device for dispensing formulation. - As shown in
FIGS. 2-3 , thefitment 32 may further include afilter assembly 92 for allowing passage of product through thefitment 32, and to prevent passage of certain solids therethrough. Thefilter assembly 92 ofFIGS. 2-3 includes afilter 96 and acage 100. Thefilter 96 abuts an upstream end of theorifice 88 that passes through thefitment 32, and is held in place by thecage 100. Thefilter 96 is substantially made from batting (e.g., polyester batting) and prevents passage of solids. In some embodiments, thefilter 96 may be formed from one or more different materials. In the assembled state shown inFIG. 2 , thecage 100 is adhesively bonded to thefitment 32, thus securing thefilter 96 in place. In some embodiments, thecage 100 may be affixed to the fitment through mechanical means (e.g., a threaded or pronged connection) or may be formed integrally with thefitment 32. - The cavity 68 may contain a first volume of
product 104 therein. The first volume ofproduct 104 is separate from any product contained within thecapsule 76 that is also contained within the cavity 68, as described below. The first volume ofproduct 104 may include a colorant, a developer, a lotion, a cream, a diluter, a liquid, and/or combinations thereof. Thefirst volume 104 may range from about 1 ml to about 100 ml, e.g., about 5 ml, about 10 ml, or any other value in that range. - As shown in
FIG. 2 , thecapsule 76 is contained within the cavity 68 of thepouch 24. In use, thecapsule 76 contains a second volume ofproduct 108, which may differ from other products contained within the cavity 68. The second volume ofproduct 108 may capsule include colorants, developers, lotions, creams, diluters, other liquids, and/or combinations thereof. Thesecond volume 108 may range from about 1 ml to about 100 ml, e.g., about 5 ml, about 10 ml or any other value in that range. Thesecond volume 108 may be selected such that a ratio between the first volume and the second volume -
- may be about 1.0 or another ratio, for example from about 0.1 to about 10.0, e.g., about 2.0, about 3.0, about 4.0, about 5.0, about 6.0, about 7.0, about 8.0, about 9.0, or about any other value in that range.
- The
cartridge 20 ofFIG. 2 includes asingle capsule 76. Some embodiments may include a plurality of capsules within the cavity, for example about two capsules to about ten capsules, e.g., 3, 4, 5, 6, 7, 8, or 9 capsules. In embodiments with more than one capsule, each capsule may contain a same or different product as other products contained within the cavity, and each capsule may contain the same or different volume of product as other capsules. For example, an embodiment may include two capsules contained within the cavity; a first capsule may contain a first volume of a first product, and a second capsule may contain a second volume of a second product. As another example, an embodiment may include three capsules contained within the cavity; a first capsule may contain a first volume of a first product, a second capsule may contain a second volume of a second product, and a third capsule may contain a second volume of a third product. In any embodiment, the volume of product in each capsule may be selected in order to create a precise ratio in relation to one or more other products; this ratio may range from about 0.1 to about 10.0. For example, in the embodiment ofFIGS. 1-4 , thefirst volume 104 may be a colorant and the second volume 108 (in the capsule) may be a developer. The ratio between the first volume 104 (of colorant) and the second volume 108 (of developer) may be about 1.0. - The
capsule 76 ofFIG. 2 is a frangible ampoule, such as may be formed substantially from glass. In some embodiments, the capsule may be frangible, but may have a form other than an ampoule, e.g., a glass bead or another shape. As such, thecapsule 76 is designed to rupture or break with the application of a sufficiently large crushing force or bending force. For example, thecapsule 76 may be designed to rupture as a result of application of a crushing force or a bending force. However, thecapsule 76 may be resistant to crushing and bending forces likely to be experienced during commerce, such as during e-commerce fulfillment. In embodiments with more than one capsule, at least one capsule may be selected to rupture as a result of application of a different crushing force or a different bending force as compared to another capsule. For example, an embodiment may include a first capsule and a second capsule, with the first capsule configured to rupture from the application of a first crushing force or a first bending force, and the second capsule configured to rupture from the application of a second crushing force or a second bending force that is different (greater or lesser) than the first crushing force or first bending force. For safety, the capsule(s) may be substantially formed from a material selected such that when ruptured, the capsule does not form particles, shards, or other debris having a smaller size than will be captured by the filter. In any embodiment, any capsule may include one or more features, for example a particular shape or one or more bumps, ridges, or other textures formed upon the surface that may be felt with a human hand through the first and/or second outer layers. For example, a cartridge may include a first capsule having a first shape and a first texture, and a second capsule having a second shape and a second texture. The ability to identify a particular capsule or type of capsule may be necessary in certain embodiments, such as those with more than one capsule. The identification of certain capsules may additionally or alternatively be facilitated if capsules have different shapes and sizes. In an embodiment, the pouch may contain a first component and a second component that are configured to break a capsule when moved away from each other. - In some embodiments, the capsule may not be frangible (e.g., may not be an ampoule), but instead may be relatively soft, such as a bead having a flexible membrane that encloses a volume of product. In such embodiments, the flexible membrane may be substantially formed of one or more materials that are selected to avoid adverse chemical reactions with products contained within the cavity. In some embodiments, the capsule may be a solid composition of product.
- In use, a user may selectively rupture at least part of the one or more capsules to release product contained therein into the cavity, where the released product may mix with other products in order to create a mixed formulation, which may then be dispensed through the fitment. Referring to the cartridge of
FIGS. 1-4 , the user may rupture thecapsule 76 by applying a crushing force to thecapsule 76 through thefirst side 36 and/or thesecond side 40 of thepouch 24, or by applying a bending force to thecapsule 76. This causes thecapsule 76 to release the second volume ofproduct 108 into thepouch 24, where it mixes with the first volume ofproduct 104. To uniformly mix the first and second volumes ofproduct capsule 76, the user may shake thecartridge 20 for a time period, e.g., at least 5 seconds, at least 10 seconds, at least 30 seconds, or about 5 second to about 30 seconds. To facilitate uniform mixing, some embodiments may include one or more beads or other solid components within the cavity. - Subsequently to rupturing the
capsule 76 and mixing the contents of thepouch 24, the user may dispense the mixed product from thepouch 24. As one example, the user may apply pressure to the pouch 24 (such as with a hand or device) in order to expel the mixed formulation from thefitment 32. As another example, the user may apply negative pressure to the fitment 32 (such as with a pump or other device) in order to draw the mixed product therefrom. As the mixed product is dispensed from thepouch 24, thefilter 96 prevents certain solids from being dispensed from thepouch 24, e.g., glass shards from the rupturedcapsule 76. - Any of the cartridges described herein may be utilized in conjunction with a device and/or system, for example a hair coloration system that includes a device that configured to apply formulations to a subject's hair and/or scalp. Referring to
FIG. 1 , thecartridge 20 is shown schematically as part ofhair coloration system 112, which includes ahair coloration device 116. Thecartridge 20 is configured for use with thedevice 116. Representative systems for the application of hair and scalp treatment formulations include those disclosed in U.S. patent application Ser. Nos. 15/721,659, 15/721,668, 15/721,678, and 15/721,682. Such devices may include a handle configured to be grasped by the hand of a user, and a head having a plurality of nozzles from which the coloring formulation is discharged. Cartridges described herein may be received within a chamber located with the head, the handle, or another component of such devices. In particular, cartridges may be coupled with the device, such as by engaging the fitment of the cartridge with complimentary structure of the device in order to establish fluid communication between the cavity of the cartridge and the device, such that products contained within the cartridge may be dispensed through the device. When the products contained within the cartridge are exhausted, the cartridge may be removed from the device and replaced with another cartridge. Further, installation of the cartridge within the device may break the capsule within the cartridge, such as by using a component of the handle of the device to break the capsule. - Referring now to
FIG. 5 , acartridge 200 is formed in accordance with another representative embodiment of the present disclosure. Thecartridge 200 is similar to thecartridge 20 ofFIGS. 1-4 in many respects. For example, thecartridge 200 has afirst side 204 and asecond side 208 forming acavity 212 therebetween, eachside first side 204 includes avent apparatus 216 to facilitate the release of gasses that may accumulate within thecavity 212. A portion of thefirst side 204 is hidden inFIG. 5 to reveal thecavity 212, which contains afirst volume 220 of a first colorant. Unlike thecartridge 20 ofFIGS. 1-4 , thecartridge 200 ofFIG. 5 contains a plurality of capsules within the cavity. Afirst capsule 224 contains a second volume of a developer. A similarsecond capsule 228 contains a third volume of a second colorant. A similarthird capsule 232 contains a fourth volume of a third colorant. Thecavity 212 also contains a mixing bead 236. In use, the first, second, andthird capsules - In the foregoing description, numerous specific details are set forth in order to provide a thorough understanding of the exemplary embodiment of the present disclosure. It will be apparent to one skilled in the art, however, that many embodiments of the present disclosure may be practiced without some or all of the specific details. In some instances, well-known features, subassemblies, and/or process steps have not been described in detail in order not to unnecessarily obscure various aspects of the present disclosure. Further, it will be appreciated that embodiments of the present disclosure may employ any combination of features described herein. For instance, any feature or configuration described above with respect to one wiping assembly may be adapted for use with any other wiping assembly.
- Although certain descriptive terms have been used to illustrate or describe certain aspects or benefits of the present invention, they should not be seen as limiting. For instance, the present disclosure also includes references to directions, such as “first,” “second,” “third,” etc. These references and other similar references in the present disclosure are only to assist in helping describe and understand the exemplary embodiments and are not intended to limit the claimed subject matter to these directions.
