FIELD OF TECHNOLOGY

[1] The present invention relates to stored heat hair appliances wherein the appliance is composed of one or more layers of heat-retaining materials such as natural heat-retaining materials, including but not limited to grains, legumes, nuts, seeds, clay, and/or stones, man-made heat-retaining materials, including but not limited to beads and/or gels of silicon or glycerin, or combinations of natural and man-made heat-retaining materials. As non-limiting examples, the invention relates to curling irons, crimping tools, straightening irons, traditional (non-powered) hair brushes and combs, heated hair brushes and combs, dryers, hot air dryer brushes, hair rollers, hair caps and bonnets, and similar hair appliances. The stored heat hair appliances of the present invention may be heated by conventional sources such as having an electrically powered, battery charged, solar powered, or rechargeable heating unit. Alternatively, the stored heat hair appliances of the present invention may derive, retain and maintain their heating capacity exclusively from the presence of heat-retaining materials, i.e., have no electricity, battery, or other source of power of their own. In other embodiments, the appliance and/or the heat- retaining materials may be heated by exposing the appliance and/or the heat-retaining materials to hot air, including but not limited to being heated by a blow dryer, air brush, or oven, or by exposing the appliance to other known sources of heating, including but not limited to being heated by using a microwave, hot plate, oven, stove, toaster, heating pad, thermal pouch, and the like. Once the heat-retaining materials of the stored heat hair appliance have absorbed sufficient heat, the appliance then may be used to fashion or style hair. In one non- limiting embodiment, the stored heat hair appliance may be used to fashion or style hair without the need for ongoing power from electrical or battery-operated sources.

[2] Additionally, the invention includes stored heat hair appliances that can retain and release heat and/or hair additives, including but not limited to water, moisture, vapor, liquids, fragrances, gels, mousses, foams, conditioners, keratin, silicones, oils, sprays, volumizers, softening agents, powders, nano-powders, silicone, and the like. The present invention also includes separate heating housing units for the heating of the stored heat hair applications, where, in addition to heating the heat-retaining materials, such housing units may also impart said hair additives to the heat-retaining materials of the stored heat hair appliances. The invention further covers methods of heating and imparting hair additives to stored heat hair appliances, including but not limited to the use of the separate heating housing units also disclosed. It is anticipated that hair additives that may be added to the stored heat hair appliances of the present invention can be in gas form, liquid form, gel form, or solid form. As non-limiting examples, the hair additive may be water, oils, solutions, emulsions, colloids, suspensions, slurries, liquefied powders, solid powders, nano powders, including but not limited to liquefied and/or solid nano-powders s, gels, solids, dissolving solids, evaporating solids, effervescing solids, or compressed or confined gasses added to and released from the inventive stored heat hair appliances.

BACKGROUND

[3] Heat is commonly used in the styling of hair given its ability to temporarily weaken or break the hydrogen bonds present in keratin, a protein found in hair that provides hair with its intrinsic shape. Once such hydrogen bonds are weakened or broken, the hair can be reshaped thus allowing curly hair to be straightened, straight hair to be curled, and multiple variations thereof. The styling effects of heat on hair are temporary, however, requiring the need to repeatedly expose the hair to heat to obtain the desired hairstyle.

[4] Hair appliances, such as curling irons, crimping tools, straightening irons, traditional hair brushes and combs, heated hair brushes and combs, dryers, hot air dryer brushes, hair rollers, hair caps and bonnets, and the like, contain heated surfaces that interact with hair to cause such conformational changes in keratin structure. Traditionally, such hair appliances are electrically powered devices where metal elements convey the heat and the electricity is continuously applied to maintain such heat. Less commonly, hair appliances can be heated using batteries, rechargeable or disposable, or other sources.

[5] There is a need for stored heat hair appliances capable of containing hair additives, including but not limited to water, moisture, vapor, liquids, fragrances, gels, conditioners, keratin, silicones, oils, sprays, volumizers, softening agents, powders, nano powders, and the like, and releasing such components as part of the styling process to help minimize damage to the hair. Additionally, heated hair appliances that minimize the use of metals and corrosive materials are also desirable.

[6] There is also a need for hair appliances that do not require conventional methods of heating, such as ongoing electrical or batter-operated power, but instead are operative primarily, or exclusively, based on presence of heat-retaining materials. Hair appliances that are electrically powered have significant disadvantages. Such electrically powered hair appliances are of limited use in wet environments and require access to power outlets that are convenient to the styling of hair, i.e., outlets near mirrors or in large spaces where the user can freely maneuver. An additional disadvantage of electrically powered hair appliances is that it is difficult for such appliances to also contain hair additives, including but not limited to water, moisture, vapor, liquids, fragrances, gels, conditioners, keratin, silicones, oils, sprays, volumizers, softening agents, powders, nano-powders, and the like. Steam and/or moisture, for example, can reconfigure hair keratin and assist with hair styling. Steam-generating and/or moisture generating components, however, may damage the electrical circuits or corrode the metal components of electrically powered appliances. At a minimum, incorporating components containing hair additives, such as components filled with fragrances, conditioners, liquids, gels, oils, powders, nano powders, and the like requires separation of such elements from electrical components, complicating the manufacturing process and presenting safety and operational risks if such separations fail. As an additional issue for electrically powered hair appliances, the cords associated with such appliances can interfere with the styling process by the user. The cord may tangle in the hair, limit the reach of the user, and/or displace other items in the vicinity when it is moved, such as by knocking brushes or clips off nearby surfaces.

[7] Battery-operated hair appliances have similar disadvantages to electrically powered hair appliances. Wet environments can cause electric shock, device damage, and/or battery corrosion. The inclusion of components containing hair additives, such as components filled with fragrances, conditioners, silicones, liquids, gels, oils, powders, nano-powders, and the like, into battery operated hair appliances is also incompatible with most battery operated hair appliances due to the risks to the battery and/or its wiring and metal components. At a minimum, costly separations are required. Finally, battery-operated hair appliances may not produce sufficient power to evaporate water, fragrances, gels, conditioners, keratin, silicones, oils, powders, nano-powders, solids and the like, and/or to properly heat the appliance.

[8] Even if the stored heat hair appliances of the present invention are powered by electrical battery, or other traditional power sources, the inclusion of heat-retaining materials as taught by this invention can perpetuate or enhance the heat provided by such power, for example, by allowing the appliances to stay at the desired temperature for longer periods of time and/or requiring less power to reach the same temperature. Heat-retaining materials also may improve heat recovery of the hair.

[9] In summary, there is a need for heated hair appliances that avoid some or all of the disadvantages associated with electrically powered or battery powered hair appliances. There is also a need for better functioning cord-free heated hair appliances. There is further a need for better functioning battery-free hair appliances. There is also a need for heated hair appliances that may be used safely in wet environments, as well as items that may not have to be continually plugged in, such as where a styling location does not contain electrical outlets. There is also a need for hair appliances that do not operate solely on conventional methods of heating, such as ongoing electrical or battery-operated power, but instead use heat retaining materials to perpetuate and/or enhance heat. Finally, there is a need for separate heating housing units for the heating of the stored heat hair applications, where, in addition to heating the heat- retaining materials, such housing units may also impart said hair additives to the heat-retaining materials of the stored heat hair appliances.

[18] In one contemplated embodiment, the heat-retaining materials of the stored heat hair appliance are enclosed within natural or synthetic fabrics in enclosures, such as pockets, sleeves, compartments, pouch, cartridges, or other forms of confinement, where such enclosures may be permanently sealed and/or may be able to be opened and closed. Examples of natural or synthetic fabrics that may be used to enclose the heat-retaining materials of the stored heat hair appliance include but are not limited to cotton, cotton blends, flannel, felt, hemp, burlap, canvas, wool, percale, polyester, cotton-polyester combination fabrics, silks, satin, sateen, velvet, nylon, bamboo, and/or proprietary fabrics, including but not limited to waterproof and breathable fabrics such as Gore-Tex, Hyvent, and the like, as well as thermal textiles. In further embodiments, the heat- retaining materials of the stored heat hair appliance may be enclosed by or affixed to the appliance with enclosures containing plastic, fiberglass, metal, rubber, composite or carbon material components, including but not limited to, stainless steel foil-coated heat reflective fiberglass cloth, high temperature heat reflective aluminum coated fiberglass, radiant and heat reflective dual coated aluminum film, silicone rubber cushion fabric, high temperature and heat reflective aluminum foil coated fabric, ceramic fiber paper, ceramic fiber blanket, fiberglass, radiant and graphite foil, acrylic fiber with PTEE impregnation square braided gasket rope, Nomex products, ceramics, and/or carbon fiber, graphene, and all carbon products. A combination of fabric and plastic, fiberglass, metal, rubber, composite, or carbon material components may also be used as enclosures for the heat-retaining materials of the stored heat hair appliance. The enclosures for the heat- retaining materials may be solid, a mesh, have perforations, or have other variations in texture and coverage. The materials described for enclosures can another be used to create a surface covering the heat-retaining materials, i.e., as a barrier between the heat- retaining materials and the hair.

[19] In another contemplated embodiment, the heat-retaining materials of the stored heat hair appliance alone are affixed directly to, and/or create the structure of, said hair appliance.

[20] As noted previously, the heat-retaining materials of the stored heat hair appliance may be a permanent or replaceable component of the stored heat hair appliance. For stored heat hair appliances that use permanent heat-retaining materials, the choice of the heat-retaining materials and/or their enclosure preferably should be chosen to minimize the potential for mold, bacteria, fungus, viruses, and/or undesirable smells, particularly if said stored heat hair appliance is used in combination with water, gels, silicones, oils, powders, nano powders, or solids. For stored heat hair appliances that have replaceable heat-retaining materials, the choice of the heat-retaining materials is less limited.

[21] Replaceable heat-retaining material components used in the stored heat hair appliance may be affixed to said appliance by any fastener or fixative known in the art, including but not limited to hook and loop structures, zippers, snap-and-fit components, slidably engaging components, buttons, latches, hinges, snaps, glues, clips, and/or pins.

Replaceable enclosures that are already prefilled with heat-retaining materials, alone or in combination with hair additives, can also be used.

[22] The heat-retaining materials of the stored heat hair appliance and/or the stored heat hair appliance itself may be heated using any traditional heating methods known in the art. One option is for the stored heat hair appliance to be corded, preferably with a retractable, removable, or windable cord, and obtain heat from an electrical source via an outlet. The stored heat hair appliance may also have a battery component, with a traditional chemical battery and/or a rechargeable battery, or a solar powered battery source, or, alternatively, the stored heat hair appliance may be chargeable via a usb cord, charging mat, or other charging devices. Another example of a source for the heat for the stored heat hair appliance is a cartridge or product utilizing butane, propane, methane, or other types of gases and/or liquids.

[23] More preferably, as a non-limiting example, the heat-retaining materials of the stored heat hair appliance, a replaceable component of said appliance, or said appliance as a whole may be heated using a heating housing unit. Heating housing units, also known as appliance“ovens,” are known in the hair-styling arts and are used to heat, superheat, or maintain a certain temperature for brushes and/or traditional hair appliances. Other examples of apparatuses that may be used to heat the heat-retaining materials of the stored heat hair appliance or said appliance itself include, but are not limited to, microwaves, stove-top heating, a hot plate, boilers, cookers, ovens, infrared sources, ultrasonic sources, solar sources, thermal pouches, or electricity or battery-operated (rechargeable or disposable) heating units, corded, cordless, or chargeable using usb chargers, charging mats, or other energy generating products. One of ordinary skill in the art will be familiar in how to make heating apparatuses that are compatible with the heat-retaining materials of the stored heat hair appliance and/or the stored heat hair appliance itself. Additionally, those of ordinary skill in the art also will be familiar with how to heat the heat-retaining materials of the stored heat hair appliance and/or the stored heat hair appliance itself to specific and optimal temperatures for hair styling.

[24] In other embodiments, the heat-retaining materials of the stored heat hair appliance, a replaceable component of said appliance containing the heat-retaining materials, or the stored heat hair appliance as a whole may further include hair additives. Hair additives include, but are not limited to, water, moisture, vapor, liquids, fragrances, gels, conditioners, keratin, silicones, oils, sprays, volumizers, softening agents, powders, nano powders, and the like. Non- limiting examples of hair additives that may be used in the present invention, alone or in any combination, include, but are not limited to, solid, liquid, and/or gaseous forms of tap water, distilled water, and/or waters infused with fragrance, fruits, or vegetables; solids, powders, nano-powders, or liquids containing cannabis leaves, extracts, oils, fabrics or other type similar products; teas in solid, liquid, evaporated, powdered, or nano-powdered forms, including but not limited to herbal and spiced teas; fruit products in solid, liquid, evaporated, or powdered form, including but not limited to juices, fruit peels, fruit flesh, seeds, pits, or other components, including but not limited to the fruits of apple, cherry, pomegranate, grape, banana, coconut, cucumber, apricot, plum, berries, kiwi, lime, lemon, orange, grapefruit, and/or melons; honeys and sugars, natural or manmade; fragrant oils, gels, mists, liquids, or

evaporable/dis solving/effervescent solids, including but not limited to the fragrances of lavender, jasmine, iris, rose, orchid, lily, lilac, plumeria, magnolia, mint, peppermint, spearmint, nutmeg, cinnamon, rosemary, mint, basil, thyme, cardamom, sage, lemongrass, patchouli, licorice, almond, vanilla, chocolate, peanut, pecan, olive, coconut, pumpkin, sandalwood, cedar, juniper, rosehip, tea tree, eucalyptus, musk, citronella, citrus and/or fruit fragrances, essential oils, and/or proprietary scents, perfumes, fragrances, oils, silicones, or gels. Additives may also include gels, mousses, foams, sprays, volumizers, softening agents, oils, keratin, silicones, and other products applied to hair.

[25] Hair additives in liquid form may be comprised of a single liquid, a mixture of liquids, or solids and/or powders suspended in liquids, e.g., solutions, emulsions, colloids, suspensions, liquefied powders, gels, or slurries. As one example, the hair additive may be a nano-powder mixed with fluids. As another example, crushed organic matter, such as flax seeds, may be mixed with fluids.

[26] The invention also includes methods of applying and/or including the one or more hair additives to the heat-retaining materials of the stored heat hair appliance, a replaceable component of said appliance containing the heat-retaining materials, or the stored heat hair appliance itself. In one non-limiting embodiment of the method, the user applies the one or more hair additives to the heat-retaining materials, their enclosures, a replaceable component of the stored heat hair appliance containing the heat-retaining materials, and/or to the stored heat hair appliance itself, prior to heating. As an alternative method, the user applies the one or more hair additives after heating. In another method, the heating housing unit applies the hair additive to the heat-retaining materials, their enclosures, a replaceable component of the stored heat hair appliance containing the heat-retaining materials, and/or to the stored heat hair appliance itself, before, during, and/or after the heating process, doing so by any known methods for applying additives, including but not limited to spraying, misting, coating, soaking, and/or the use of evaporation or condensation processes. As an additional method of applying and/or including the one or more hair additives, the additives may be pre-mixed with the heat-retaining materials or combined with the enclosure for said heat-retaining materials. For example, the heat-retaining materials could be pre-soaked, coated, or otherwise combined with water, oils, flowers, fragrance or essential oils, conditioners, keratin, silicones, spices, herbs, and the like.

Alternatively, the fabric or material enclosing said heat-retaining materials could be dampened, coated, woven, infused, or constructed such that they contain trapped water, vapor, condensation, conditioners, oils, fragrances, gels, keratin, silicones, powders, nano powders, and/or essential oils, and/or solid materials such as spices, flowers, seeds, and/or herbs. As another embodiment, replaceable components for the stored heat hair appliance that are already prefilled with heat-retaining materials in combination with hair additives can be used.

[27] In a further non-limiting embodiment, the stored heat hair appliance may have one or more compartments separate from or combined with the heat-retaining materials where said compartments may release, such as by motion sensor, light, trigger, switch, or button, the desired one or more hair additive from the stored heat hair appliance and/or into the heat- retaining materials and/or their fabric or material enclosures during the hair styling process.

4, the hair curler heating apparatus 450 consists of a heated surface 40 that heats the hair curlers 400. The heated surface 40 of the hair curler heating apparatus 450 may optionally contain holes 42 from which heat or hair additives, including but not limited to water, moisture, vapor, liquids, fragrances, gels, conditioners, keratin, silicones, oils, sprays, volumizers, softening agents, powders, nano-powders, and the like, may escape and infuse the hair curlers 400. The hair curlers are comprised of ends 44 that the user may touch during the styling process and the roller core 46, which comprises the heat-retaining materials 48. One option for heating the curlers is a charging mat, 49, such as one that can be charged by usb as depicted in Fig. 4. Any other forms or methods for heating may also be used. As one non- limiting example, the hair roller could be non-powered, wherein the heat-retaining materials are heated by external means such as hot air, a hot plate, a heated housing unit, see Figure 6, microwave, or other heat-providing source.

[47] Fig. 5 depicts another preferred embodiment of a stored heat hair appliance where the appliance is a hot air dryer brush 500. In Fig. 5, the hot air dryer brush 500 comprises bristles 52 affixed to or integrally formed with an upper surface 50. As depicted in Fig. 5, the heat-retaining materials 56 are beneath the upper surface 50. In alternative

embodiments, the heat-retaining materials 56 themselves could form the upper surface 50 and/or bristles 52.

[48] The upper surface 50 of hot air dryer brush 500 may optionally contain holes 54 from which hot air, heat, or hair additives, including but not limited to water, moisture, vapor, liquids, fragrances, gels, conditioners, keratin, silicones, oils, sprays, volumizers, softening agents, powders, nano-powders, and the like, escapes. The upper surface 50 and/or bristles 52 of the hot air dryer brush 500 are heated by hot air generated by an internal dryer component not shown.

[49] Figs. 1-5 are only illustrative examples of stored heat hair appliances of the present invention. Any hair appliance that applies, directly or indirectly, heat to hair may be modified to include heat-retaining materials at or above the surface closest to the hair or below such a surface and, optionally, hair additives.

[50] Figs. 1-5 further do not show every potential source of heat for the stored heat hair appliances. As noted previously, in one preferred embodiment, the stored heat hair appliances or the heat-retaining materials themselves may be heated using heated housing units, also known as appliance“ovens,” which are known in the hair-styling arts. An example of an appliance oven 600 is shown in Fig. 6. Other examples of apparatuses that may be used to heat the heat-retaining materials of the stored heat hair appliances, and/or the heat-retaining materials comprising such appliances, include, but are not limited to, microwaves, stove-top heating, a hot plate 650, as shown in Fig. 6, boilers, cookers, ovens, infrared sources, ultrasonic sources, solar sources, thermal pouches, or battery- operated (rechargeable or disposable) heating units. [51] As depicted in Fig. 6, hair additives in liquid form, including but not limited to water 60, oils 62, solutions, conditioners, keratin, silicones, and/or gels, may be added to the heated housing units and/or apparatuses for heating the stored heat hair appliances and/or heat-retaining materials comprising such appliances. Other hair additives, including in gaseous and solid forms, may also be added (not shown).

[52] In other embodiments, not shown, the stored heat hair appliance and/or the heat- retaining materials may obtain heat from an electrical source via an outlet, preferably via a retractable, removable, or windable cord. The stored heat hair appliance may also, alternatively, have a battery component, with a traditional chemical battery and/or a rechargeable battery, or a solar powered battery source, or, alternatively, the stored heat hair appliance may be chargeable via a usb cord, charging mat, or other charging devices. Another example of a source for the heat for the stored heat hair appliance is a cartridge or product utilizing butane, propane, methane, or other types of gases and/or liquids.

[53] Fig. 7 provides examples of the potential placement of the heat-retaining materials and/or hair additive in relationship to the surface that contacts or is closest to the hair in the stored heat hair appliance. In placement 700, the heat-retaining material 72 forms the surface closest to the hair 70. In placement 710, the heat-retaining material 72 is placed below an upper surface 74. This upper surface could be solid, mesh, or perforated fabric, plastic, fiberglass, metal, rubber, composite, and/or carbon material component or the like. In placement 720, the heat-retaining material 72 is placed below an upper surface 74 that further contains an overlay 75. Overlays 75 may include, for example, hook and loop structures that smooth the hair, where such hook and loop structures are separate from or integrally formed with the upper surface 74. In placement 730, the heat-retaining material 72 is combined with a hair additive 76 and is placed below an upper surface 74. In placement 740, the hair additive 76 is separated from the heat-retaining material 72, both of which are placed below an upper surface 74. The placements depicted in Fig. 7 should not be considered limiting; there are many other placements possible for the heat-retaining material, such material could be added in layers, and or other components - such as heat reflective layers, air pockets, and the like - may also be used in the stored het hair appliances of the current invention.
