The present invention relates to a hair-setting tool such as a hair brush or comb, one or more hair rollers, hair curling tools, a hot-air styling brush, a hair straightener or crimper, a curling iron, a spiral iron, a hair waver or crimper, and the like, and more particularly to a heat-enhanced hair-setting tool, which provides heat while setting hair so as to improve the hair-setting performance and efficiency of the hair-setting tool.
Many hairstyling appliances utilize heat to encourage hair to assume a new shape or desired style. For example, styling techniques may include drying, straightening, curling, and crimping. It generally takes a long time to set hair with a hair brush, hair comb, hair roller, hair dryer and/or hair straightener in order to have a satisfactory hair style. Most hair brushes, combs and rollers do not have heating functions or components, and thus the user must work with a direct heat source such as a blow dryer. Heat may be applied to hair for styling by blowing hot air, for example, by using hair dryers or hot-air styling brushes, which require the use of electricity. Because hot air from a blow dryer or a hot-air styling brush reaches not only the hair but also the scalp, which is more heat-sensitive than hair, the temperature needs be carefully controlled to protect the scalp. However moderating the temperature to avoid overheating skin limits the effectiveness of hair-setting.
Some hair-setting tools use electricity to achieve the heating purpose. In this case, heat is directly applied to the hair, for example by using styling irons or hot rollers, or other hair-setting tools. However, these traditional tools may be noisy, limit movement of the user due to wires, use electricity, and create hazards given that they are typically used in bathrooms near sources of water.
There thus is a need to develop a heat-enhancing delivery system for styling hair, such as heat-enhanced hair-setting styling tools capable of efficient heat conductivity compared to conventional styling tools. There is also a need for such tools that minimize damage to the hair, improve the setting performance of the tool, are convenient to use, require less electricity, may cause less damage to the hair than conventional items currently on the market, and/or may reduce the weight of such items.
The present invention provides heat-enhanced hair-setting tools capable of more efficient heat transfer than conventional hair-settling tools with little or minimized damage to hair that may improve the setting performance of the hair-setting tool while being convenient to used. The hair-setting tools of the present invention are designed to include one or more heating components that allow for heat and steam to be retained, generated, and/or reflected after heating for an extended period of time.
According to one embodiment of the present invention, the hair-setting tool may include a body and a heating component disposed substantially within, or entirely within, said body, wherein said heating component conveys heat and/or steam indirectly or directly to the hair of the user.
According to other embodiments of the present invention, the hair-setting tool may include a body and a heating component disposed at least in part on top of the body of the hair-setting tool, wherein said heating component conveys heat and/or steam indirectly or directly to the hair of the user.
In certain embodiments of the present invention, the heating component may comprise one or more sheets of metal foil, one or more lengths of heat-conductive wire, and/or one or more lengths of heat-conductive tape.
In certain embodiments of the invention, the body of the hair-setting tool may have holes or vents through which the heat and/or steam from the heating component may dissipate from the body of the hair-setting tool.
According to certain embodiments of the present invention, the hair-setting tool may also be a brush and have a supporting base and bristles. In one such embodiment, the hair-setting tool may be a cushion brush hair-setting tool, wherein said bristles protrude from a cushion member disposed on the supporting base of the body. In other embodiments, the hair-setting tool may be a detangling brush hair-setting tool, wherein the bristles protrude from the supporting base of the body of the hair-setting tool. In further embodiments, the hair-setting tool may be a round brush hair-setting tool, a vent brush hair-setting tool, and/or a hot air brush hair-setting tool. In certain embodiments wherein the hair-setting tool is a brush, the heating component may be disposed on the surface opposite or adjacent to the bristles of the hair-setting tool rather than on the same surface as the bristles.
In other embodiments of the invention, the hair-setting tool may be a smooth barrel hair-setting tool, a covered barrel hair-setting tool, one or more hair roller hair-setting tools, a hair straightener hair-setting tool, and/or a curling iron hair-setting tool.
In another embodiment of the present invention, the hair-setting tool further includes a protective layer disposed in whole or in part on one or more surfaces of heating component. This protective layer may protect the other portions of the hair-setting tool or the user's hair from the heating component. In certain embodiments, the protective layer may contain one or more holes from which heat and/or steam from the heating component may dissipate. In certain embodiments, the protective layer may comprise a carpeting structure, wherein said carpeting structure comprises a plurality of mini-posts, hook posts, loop posts, curved posts, and/or Velcro or Velcro-like loops.
According to further embodiments of the present invention, the hair-setting tool may include a body, wherein all or a portion of the body is covered with a paint, and a heating component, wherein said heating component is the paint covering all or a portion of the body and wherein the paint generates heat or retains heat that assists in setting hair. One non-limiting example of such an embodiment would be a hair-setting tool wherein the paint comprises graphene or other carbon-based materials.
The above contents of the present invention will become more readily apparent to those ordinarily skilled in the art after reviewing the following detailed description and accompanying drawings, in which:
Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in
The present invention provides heat-enhanced hair-setting tools capable of more efficient heat transfer than conventional hair-settling tools with little or minimized damage to hair that may improve the setting performance of the hair-setting tool while being convenient to used. The hair-setting tools of the present invention are designed to include one or more heating components that allow for heat and steam to be generated, retained, and/or reflected after heating for an extended period of time.
A variety of combs and brushes for smoothing hair are commercially available for use by consumers. A comb and a brush are different in shape and manufactured in different ways. However, both combs and brushes have a supporting base and a plurality of projections, e.g. teeth (combs) or bristles (brushes), where the projections protrude from the supporting base. In general, the teeth of a comb are integrally formed with the supporting base with the same material. In comparison, the bristles of a brush may be integrally formed with the supporting base, secured onto the supporting base, or removably mounted onto the supporting base. Additionally, special comb or brush designs have also been developed and may be used to enhance hair-smoothing effects or for additional functions. Taking brushes as examples, a cushion brush hair-setting tool 10A according to an embodiment of the present invention is illustrated in
Each of the cushion brush, detangling brush, and the round brush hair-setting tools has a supporting base 11 and a plurality of bristles 12 protruding from the supporting base 11. The bristles 12 may be integrally formed with the supporting base 11 or attached onto the supporting base 11. As just one example, as shown in
According to embodiments of the present invention, a specially designed heating component, which will be described in detail later, is provided to hair-setting tools to enhance hair-setting performance. The hair brushes equipped with said heating component may be used with or without the aid of a blow dryer.
In an embodiment of the hair-setting tools of the present invention, the heating component is disposed entirely inside the body of the hair-setting tool. For example, the heating component (not shown) may be accommodated in a space 101 within a hollow supporting base 11 of the cushion brush hair-setting tool 10A shown in
In another embodiment, the heating component may be disposed in whole or in part on an exterior surface of the hair-setting tool.
In certain embodiments, a protective layer may be provided to protect the user's hair or the other components of the body of the hair-setting tool from the heating components. For example, as shown in
In certain embodiments, the protective layer 106 may be made of a material which is heat-resistant to avoid damage by heat from the heating component 105. In other embodiments, the protective layer 106 should be made of a material with a thickness and/or configuration that allows heat to transfer from the heating component 105 to hair through at least one of conduction, convection and/or radiation. According to one embodiment, the protective layer 106 may be porous so that heat can be dissipated through the tiny holes (not shown) to reach the hair of the user.
Another embodiment of the hair-setting tool of the present invention is the covered barrel hair-setting tool 30 illustrated in
In some embodiments, the carpeting structure 15 of the hair-setting tool 30 may include a plurality of mini-posts, hook posts, loop posts, curved posts, or Velcro or Velcro-like loops, which may be used, inter alia, for smoothing hair. In certain embodiments, the carpeting structure 15 may also be enhanced or adapted to moderate the heat from the heating component 105 and protect the hair of the user from direct contact with the heating component. In such embodiments, the carpeting structure 15 functions substantially similar to the protective layer 106 describe above. In an alternative embodiment not shown, a protective layer may be placed between the heating component and the carpeting structure.
Similarly, the cushion member 13 included in the cushion brush as shown in
In a further embodiment of the present invention, as illustrated in
In
In certain embodiments, the bristles 12 of the hair-setting tool 60 and heating component 105 are both heat-conductive, further improving by the hair-setting properties of the hair-setting tool 60 However, since the bristles 12 might directly contact scalp of a user, the temperature of the heating component 105 may be controlled in a relatively strict manner, or, alternatively, the bristles 12 may be less heat-conductive than the heating component 105.
In addition to combs, brushes or similar hair-setting tools, the hair-setting tools according to the present invention also include hair roller hair-setting tools.
Another embodiment of a hair roller hair-setting tool of the present invention is the hair roller hair-setting tool 100A shown in
The functions and properties of the heating component 205 and the protective layer 206 are similar to the above-described heating component 105 and protective layer 106 respectively, and the disclosures associated with the heating component 105 and protective layer 106 are herein incorporated by reference.
In certain embodiments, the heating components 105 and 205 of the present invention may partially cover the hair-setting tools.
In certain embodiments of the hair-setting tools of the present invention, the hair-setting tool may be a hair straightener, hot air brush, or hair curler hair-setting tool, as depicted in
In a hair straightener hair-setting tool 120 of the present invention shown in
In the hot air brush hair-setting tool 130 of the present invention shown in
In the curling iron hair-setting tool 140 of the present invention shown in
The heating components of the hair-setting tools of the present invention should be capable of being conveniently heated and re-heated to a suitable temperature range and remain hot within at least a suitable operating duration. For example, a suitable temperature range may be from 100 degrees Fahrenheit to about 450 degrees Fahrenheit or higher and a suitable operating duration may be in the range of a few seconds, 15 seconds, 30 seconds, and a few minutes. The heat applied and heating time may vary based on the hair-setting tool and its desired effect. For example, a curling iron may heat faster than a roller, which needs to maintain heat for an extended period of time without electricity. Similarly, if the hair-setting tool is heated in a pouch, or using a battery charger, such a tool may take longer to heat. In certain embodiments, the hair-setting tool will be characterized by wattage rather than temperature, such as, by non-limiting example only, a hot air brush at 1100 watts.
The heating components of the hair-setting tools may be heated or-re-heated by way of a heating source such as a blow dryer, an oven, etc. Alternatively, a heating box as illustrated in
Alternatively, in certain embodiments, the heating component of the hair-setting tools of the present invention may itself be an active heating source, generating heat in any known conventional way, such as chemically, physically, or electrically.
In certain embodiments, the heating component may be in the form of a sheet. In certain embodiments, the heating component may include a plurality of sheets. In other embodiments, the heating component may be in the form of wires, tapes, papers, foils, blocks, balls, dots, micro-dots, strips, and in single layers, multiple layers, or in clusters of such forms.
In certain embodiments, the heating component may be the addition of a heat retentive or heat reflective material, additive, coating, or paint to the hair-setting tool. As a non-limiting example only, the supporting base of a brush hair-setting tool of the current invention may be coated with a paint containing graphene; the coated supporting base will cool down significantly slower and retain heat longer than a conventional brush.
In certain embodiments, the material used for the heating component in the present invention may be easily cut and configured to each chassis style, to allow for easy repair, installation, removal, and replacement.
The heating component of the hair-setting tools of the present invention may consist of any type of heat conducting, retaining, or reflecting material.
