DETAILED DESCRIPTION

Typically, most persons will use shampoo while taking a shower because it is easier to use water to lather up and then rinse the shampoo out of the hair. Such shampoo is best for cleansing but since persons prefer to shower every day, daily use of shampoo can be damaging to hair. Dry shampoo offers an alternative to washing hair while showering in order to refresh the hair between showers but does not provide as effective cleansing compared to the shampoo used in the shower.

This disclosure relates to a device for cleansing hair while out of the shower that can be used with hair cleansing formulations. In one embodiment, the device provides cleansing on par with shampoo used in the shower, and convenience on par with dry shampoo so as not to have to step into the shower in order just to wash hair. In one embodiment, the device uses a brush- or comb-like architecture that relies on a combination of mechanical and chemical action to deposit desired formulations for cleansing, removing the formulations with unwanted particulates, and further provides additional cosmetic or health attributes. The comb-like action provides a familiar gesture easy to incorporate into current beauty and haircare routines.

In one embodiment, the device removes more than “macro” particulates like dandruff. The device provides a cleansing formulation along with agitation to dissolve and absorb oils, sebum, and other odor trapping items to leave the hair with signifiers of being clean/refreshed. The device creates a mist for formulation dispersal, and includes tines for mechanical agitation, and vacuum removal to accomplish the goal of cleansing.

Because the device can clean hair on par with shampoo used in the shower, the hair is easy to style afterwards, resulting in longer term healthier hair.

Referring to FIG. 1, a device 100 for shampoo application and removal is illustrated. The device 100 is an electrically powered device including a nebulizing component for misting, spraying or atomizing a shampoo formulation and a vacuum component for removing the used shampoo and any debris or oils washed out with the shampoo formulation. In one embodiment, the shampoo formulation is a liquid shampoo formulation.

In one embodiment, the device 100 exterior shape includes one or more geometric forms, including regular or irregular forms, having cross-sections of substantially any geometric shape including circular, elliptical, conical, triangular, square, rectangular polygonal, regular or irregular shapes, or the like, as well as other symmetrical and asymmetrical shapes, or combinations thereof.

In one embodiment, the device 100 is shaped in the style of well-recognized familiar hair appliances to inspire trust and confidence in the device leading to intuitive use and gestures when using.

In one embodiment, the device 100 exterior housing can be constructed out of a variety of materials including, for example, metals and plastics, or combinations thereof.

Referring to FIG. 3, in one embodiment, the device 100 includes a handle 104 connected to the device 100 at the substantially cylindrical section. The handle 104 is connected to the device 100 at an obtuse angle with respect to the front end of the device 100. Stated differently, the center longitudinal axis of the handle 104 intersects, at an obtuse angle, the horizontal plane on which all of the tines 108 lie. The handle 104 helps balance the device weight for more comfortable use.

Still referring to FIG. 3, at the back side, the device 100 can include a smaller diameter cylindrical shaped housing 136 that accepts a removable cartridge 102 containing shampoo. The cartridge 102 can be configured to be a re-fillable cartridge or a disposable cartridge. In one embodiment, the device 100 can be configured to hold more than one cartridges.

Moving forward from the housing, 136, the device 100 exterior shape increases step-wise to a larger outer diameter portion 138 compared to the housing 136 diameter. In one embodiment, the device 100 includes a body structure that has a substantially cylindrical or minimally tapered conical portion 138 from the back end to about the middle of the device length. In one embodiment, the handle 104 connects to the back side of portion 138. Then, proximally from the cylindrical or minimally conical portion 138, the device 100 takes on a more pronounced conical or decreasing elliptical shape 140, in the top to bottom plane (i.e., viewed from left or right side), from about the middle of the device 100 to about a third or fourth of the device length. However, in the side to side plane (i.e., viewed from top or bottom) the device 100 does not taper as much, since the device 100 is accommodating three tines in the side to side plane, where the device 100 has to accommodate the height of a single tine in the top to bottom plane. Then, distally from the smaller end of the conical or elliptical shape 140, the device 100 has a transition portion 142 that forms one or more dispensing tines 108 at the front end, so that each tine 108 is separate from the other tines. In one embodiment, the tine 108 length is about one-third to about one-fourth of the device 100 length.

Referring to FIGS. 2 and 5, each tine 108 has a gradually decreasing conical shape from the initial connection at the transition portion 142 section to the end of the tine 108 in both the side to side plane and the top to bottom plane. For example, the tine 108 decreases in diameter with the forward length. While the tines 108 emanate from the same device 100 section, each tine 108 is separated from its adjacent tines, such that the space between tines 108 lengthwise is approximately the same as the average width (average diameter) of a tine or greater. Because the tines 108 decrease in diameter progressively to the tip, the space between tines conversely increases from the attachment of the tines 108 to the tip of the tines 108. In one embodiment, the device includes three tines 108 lying on the same plane, meaning that the lengthwise centerline of each tine passes the same plane. The plane on which the tines 108 lie may be viewed as the horizontal plane of the device 100, meaning that the tines 108 are centered with respect to the top and bottom of the device 100, not considering the handle 104 (FIG. 4).

In FIG. 5, the tines 108 are shown having a rounded tip when viewed from the bottom (or top) plane. However, in FIG. 3, the tines 108 are shown to have a flat area or chamfer at the bottom of the tine 108 at the front end when viewed from the side plane, resulting in a truncated rounded shape. The rounded tips of the tines 108 can part the hair for better access to the scalp and hair roots. The rounded tips of the tines include “agitation bumps” and the chamfered angle for cleansing.

In FIG. 5, the chamfered section of the tines 108 has openings 130 for dispensing the shampoo formulation. In one embodiment, the shampoo formulation can be atomized and dispensed as a mist. Additionally, the chamfered section of tines 108 has openings 132 that lead to a vacuum system for collecting the used shampoo formulation with any debris or oils removed from the hair. The vacuum openings 132 are separated from the dispensing openings 130.

In the illustrated embodiment, each tine 108 is shown having openings 130 for dispensing and openings 132 for vacuum removal. However, in one embodiment, there can be dedicated tines that only have openings for dispensing shampoo formulation and dedicated tines that only have openings for vacuum removal. In one embodiment, the device 100 is provided with three tines 108 for even cleansing coverage. The angle of the handle 104 and the tine 108 length allows users to reach all areas of the scalp for cleansing.

Referring to FIG. 6, the device 100 is represented schematically to illustrate the main components. In one embodiment, the device 100 includes a nebulizer 112.

In one embodiment, the nebulizer 112 produces a mist on demand by depressing the mist switch 106 (FIGS. 1 and 2). In one embodiment, the mist switch 106 is placed on the front side of upper part of the handle 104 to allow operation with the index finger. In one embodiment, the mist switch 106 is a momentary switch with the default position being the off position. Depressing the mist switch 106 starts the nebulizer 112 and produces mist. The nebulizer 112 is supplied shampoo formulation from the cartridge 102. Releasing the mist switch 106 stops the nebulizer and the dispensing of shampoo formulation. In one embodiment, the mist switch is a multi-positional, multi-functional, selector switch that requires positively selecting the off position to stop the nebulizer. In one embodiment, the mist switch is a multiple position selector switch that has settings for off and more than one setting for mist production, such as light or heavy mist. In one embodiment, a mist selector switch can included settings for mist and no-mist dispensing.

In one embodiment, the nebulizer 112 includes a compressor, pump, or ultrasonic wave generator to generate the mist from the shampoo formulation. In the case of a pump or compressor nebulizer 112, such nebulizer 112 causes air or the shampoo formulation to flow at a high velocity which propels the shampoo formulation through a fine nozzle designed for misting at the opening 130. In one embodiment, a hand operated pump mechanism is used to propel the shampoo formulation through the atomizing nozzle at the opening 130. In the case of a pump or compressor nebulizer, a single nebulizer 112 can be placed in the body structure of the device 110. Then, the outlet of a compressor or pump nebulizer 112 is routed through a system of conduits to each of the tines 108 and exits from the nozzle at the openings 130.

An ultrasonic wave nebulizer 112 has an ultrasonic wave generator in contact with the shampoo formulation where the frequency of the ultrasonic waves is sufficient to produce the mist. An ultrasonic wave nebulizer also includes a “mesh” nebulizer that has a vibrating mesh just touching the surface of the shampoo formulation to create the mist. Either form of ultrasonic wave nebulizer can use a piezoelectric element. In the case of an ultrasonic wave nebulizer or mesh nebulizer, the nebulizer 112 including a piezoelectric element or a piezoelectric element and mesh combination, in essence, the device 100 has three nebulizers, one for each tine 108. In the case of case of an ultrasonic wave nebulizer or mesh nebulizer, the shampoo formulation may be routed to the tip of the tines 108 there to make contact with the piezoelectric element or the piezoelectric element and mesh combination, from which the mist is then expelled through openings 130.

In one embodiment, the device 100 includes a vacuum system having a vacuum generating motor 114 and collector 116. The vacuum motor 114 includes the impeller vanes that cause a stream of air to enter through the vacuum inlet openings 132 at the tines 108. The stream of air can carry the used shampoo formulation along with any debris and oils washed out of the hair by the shampoo formulation, which then gets captured by the collector 116, and the air is expelled out of the device 100. In one embodiment, the collector 116 includes an annular vent 134 placed at the back of the device 100 and encircling the cartridge 102 (FIG. 4). The vent 134 allows the stream of air to exit the device 100, while the used shampoo and debris become trapped in the collector 116. In one embodiment, the collector 116 is removable from the device 100 and is dishwasher safe so as to allow cleaning in a dishwasher. In one embodiment, the surface of the collector 116, which contacts the used formulation shampoo, is coated with a hydrophobic or hydrophilic material to facilitate cleaning of the collector.

In one embodiment, the vacuum motor 114 is operated by the multi-positional, multi-functional, selector switch 110 (FIG. 4). A selector switch 110 can be a slide switch or a dial switch with more than two positions, or a push button switch with more than two positions, for example. In one embodiment, a vacuum selector switch 110 includes settings for off and more than one vacuum speed setting, such as high and low. In one embodiment, the vacuum switch 110 is placed on the back side of lower part of the handle 104 to allow operation with the thumb, for example. The vacuum switch 110 can be isolated for uninterrupted vacuum. Light-emitting diodes 118 can be used to light up the selected position. The selector switch 110 remains in the selected position until moved to another position. In one embodiment, a momentary switch can replace the selector switch, wherein the default position of the momentary switch is the off position, and the momentary switch has to be depressed to start the vacuum motor. In one embodiment, the device 100 includes both a vacuum selector switch and momentary switch, wherein the momentary switch is used to operate the vacuum motor when depressed, and at the speed setting on the selector switch.

The device 100 includes a power supply 118. In one embodiment, the device 100 is powered through common household alternating current that relies on an electrical cord (not shown) to supply power to the device 100. In one embodiment, the device 100 is powered through direct current, such as a rechargeable battery that can be charged by plugging into a household alternating current outlet. A direct current powered device 100 allows the device to be used without staying or standing in proximity to an electrical outlet.

Cartridges 102 are supplied filled with a shampoo formulation. Cartridges 102 can be removable from the device 100 either to be re-filled or for disposal and replacement with a new full cartridge. As seen in FIG. 1, the cartridge 102 is inserted through the back side of the device 100. The cartridge 102 is connected to the nebulizer 112 to supply the hair formulation to the nebulizer 112 through any suitable conduit to feed the nebulizer 112 with shampoo formulation when the nebulizer 112 is operated. Advantageously, the hair formulation does not need to be mixed with external water as compared to a shampoo used in the shower.

In one embodiment, the cartridge 102 has a product identification tag that can convey instructions for operation of the device 100 based on the specific formulation contained in the cartridge 102. The device 100 may include a product identification tag reader capable of reading the product identification tag and processing instructions for operation of the device based on the particular formulation. Product identification tags, include for example, bar codes, 2-D bar codes, RFID, and the like. The product identification tag is a machine readable tag that conveys the device settings for the particular formulation. Different formulations may have different device settings. For example, the product identification tags can include the vacuum setting, such as from strong, medium, and soft, and the nebulizer setting from fine, medium, or coarse droplets. In this manner, the device 100 is optimized for the particular formulation, and the user is not guessing and avoids trial and error.

Shampoo formulations can include, but are not limited to, formulations which include any one or more absorbents in a carrier. Carriers include alcohols or water. Absorbents can include cornstarch or clays, such as kaolinite, montmorillonite, smectite. A surfactant, such as fatty acid anionic surfactants, can be included to prevent lumping. If provided as a foam or aerosol, the shampoo formulation can include a gas propellant.

Referring to FIG. 7, one embodiment of cleansing hair with the device 100 is illustrated. In block 120, the vacuum motor 114 is turned on by a user. At this point, the user can be moving the device 100 to the area of scalp desired to be cleansed in preparation for dispensing the shampoo formulation.

From block 120, the method enters block 122. In block 122, the nebulizer 112 is turned on while the vacuum 114 is operating. Before turning the nebulizer 112 on, the user has moved the device 100 so that the tines 108 are at the desired location on the scalp for cleansing. The user can now depress the mist momentary switch 106 for a brief time period and then release the switch. From block 122, the method enters block 124.

In block 124, after the user presses and releases the mist switch 106 to dispense the shampoo formulation the user can agitate the scalp and hair roots with the tips of the tines 108 while the vacuum is operating. The vacuum removes the used shampoo formulation with any collected debris, such as dead hair or skin cells, and any oils or previously applied hair formulations. From block 126, the method enters block 128.

In block 128, the user moves the tines to a new area on the scalp desired to be cleaned and repeats that misting, agitation and vacuuming operations. When the entire scalp is cleansed, the user can stop the vacuum in block 128.

The device 100 allows a mechanical actions, including vacuum, “squeegee”, and wiping actions and combined with chemical action, such as surfactants and molecules capable of capturing and removing oil from hair, for cleansing the hair.

Use of the device 100 minimally impacts the hair style, the overall shape of the device is familiar to other hair appliances, such as a hair dryer, leading to simple intuitive use of the device 100. Further, the device 100 does not require hand contact with hair formulations. The device 100 allows persons to cleanse hair only when needed, to maintain the hair style longer and limit the damage to hair, as opposed to washing hair at every shower.

While illustrative embodiments have been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention.
