Definitions

  • the subject matter of this disclosure generally relates to apparatus and methods for hair care, and more specifically relates to apparatus and methods for enhanced hair product application with concurrent styling.
  • Natural hair There has been a growing trend among women of African descent to wear their hair in its natural state (hereinafter referred to as “natural hair”) choosing to eliminate the use of treatment and styling methods such as relaxing curls and straightening. Women within this growing consumer segment are choosing to preserve and enhance the natural curls present in natural hair. Natural hair requires care routines specifically designed to address the unique characteristics of natural hair. Morphological differences in natural hair comprising texture, shape, strength, elasticity, and thickness complicate the cleansing and styling process and effect the natural hair's ability to retain moisture and maintain health. Furthermore, natural hair is particularly sensitive to treatment and styling processes involving elevated heat.
  • the process for applying hair products to and styling natural hair is painstaking, messy and lengthy involving multiple separate steps comprising detangling a section of the hair using combs and/or brushes and applying hair product into the sectioned hair.
  • This process is repeated section by section and further comprises manipulating the hair to achieve the desired style.
  • the person applying product and manipulating the hair has to frequently pickup and put down hair product and pick up and put down combs and/or brushes.
  • a goal of a hair care procedure may be to add curls to otherwise characteristically straight or wavy hair
  • the process may be best achieved by first reaching a sufficient degree of plasticization to weaken hair structure, organizing the hair in its desired curl and shape, and then removing moisture, typically assisted with a high level of heat, to remove the plasticized state, thereby returning a supporting structure, or, in terms commonly used in hair care, “set the hair”.
  • many of the procedures which are promoted and used to provide for curls are in fact detrimental to curls when caring for natural hair.
  • Natural hair should ideally be nourished, moisturized, and plasticized to a first level that overcomes a characteristic brittleness, all through product absorption at temperatures and durations that do not cause plasticization of a second level that results in excessive weakening of hair structure, and furthermore, through product absorption at temperatures and durations that do not cause heat related stress.
  • Caring for natural hair outside of the home is problematic and requires a supply of hair product and styling equipment such as combs and/or brushes be present and the process described above to be performed away from home. This results in many women avoiding exercising, swimming and other desirable activities in order to avoid carrying cumbersome hair care equipment and products, followed by washing and a painstaking, messy and lengthy hair care process in a remote location.
  • hair product and styling equipment such as combs and/or brushes
  • an apparatus and method may provide for a hair care process comprising an application of hair product, hereinafter referred to as “product”, and manipulation of hair.

  • Brake pivot arm comprises brake engagement spring 796 which when installed is partially compressed between brake pivot arm 793 and housing 791 and maintains pressure and engagement between ratchet surfaces of brake pad 795 and piston control arm 716 .
  • Sufficient pressure applied to piston release bar 705 causes brake pivot arm to pivot about pivot attachment hole 794 and further compresses spring 796 , thereby releasing engaged ratcheted surfaces of brake pad 795 and control arm 716 , allowing piston 715 to move under force created by expending elastic potential energy of spring 780 and as permitted by depleting product volume within product reservoir 721 .
  • FIG. 7 m depicts a piston 715 comprising a front portion 717 comprising an inwardly sloped front perimeter, a recessed collapsible reservoir collection area 718 and a central protrusion 719 .
  • piston 715 is configured to cause excess collapsible reservoir wall material from a depleting collapsible product reservoir 721 to collapse and collect in recessed collapsible reservoir collection area 718 wherein it will not interfere with the forward movement of piston 715 and the corresponding dispensing and application of product.
  • protrusion 719 and perimeter of front portion 717 apply pressure to collapsible reservoir 721 .
  • This pressure creates fluid pressure within the product reservoir 721 which creates product flow out of product reservoir 721 , through outlet 723 and into application and on-demand heating module 707 of FIG. 7 e , thereby depleting product volume contained therein, and additionally creates outward fluid product pressure which forces collapsible reservoir material made excess by the depletion of product volume therein, into recessed collapsible reservoir collection area 718 .
  • Perimeter of front portion 717 can be inwardly sloped to mechanically assist the movement of excess reservoir wall material into recess area 718 .
  • any pressure thereon is transferred to the inner surfaces of recessed area 718 of piston 715 and therefore does not contribute to any friction or contact between collapsed reservoir material and the walls of cartridge shell 724 , and thus allows piston 715 to otherwise move freely, and elastic spring energy applied to reservoir 721 is generally directed toward generating flow of product and collapsing reservoir 721 , and not expended as frictional energy loss between reservoir 721 and cartridge shell 724 .
  • a resulting fully collapsed reservoir is depicted in FIG. 7 n .
  • the depth of recess area 718 can be such that collapsed reservoir material of a fully depleted product cartridge fills the recess and therefore minimal residual product remains after the product cartridge 720 is otherwise depleted.
  • FIG. 7 o is a perspective view of a partial inner application arm assembly 701 c comprising an alternative configuration to assembly 701 b of FIG. 7 l, wherein a piston and cartridge chamber 776 comprises an integrated product cartridge shell 799 , such that cartridge 720 of FIG. 7 g may be inserted directly into application arm 701 without the requirement to first assemble a product cartridge shell assembly 706 of FIG. 7 h .
  • This configuration may be preferable when product cartridge 720 can be stored and handled without risk of potential puncturing or rupturing.
  • product cartridge can be preferably assembled in shell 724 which can offer protection against potential puncturing or rupturing, and stored, handled and loaded as a product cartridge and shell assembly 706 into an inner assembly of the embodiment of 701 b shown in FIG. 7 l, as previously described.
  • Such selective electrical contact is thereby in relation to a location of piston 715 within piston and cartridge chamber 776 and thereby can indicate a remaining product level.
  • electrical connection between wiper contacts 774 c and 774 a is provided by conducting layer 784 until layer edge 784 a passes beyond electrical connection with wiper contact 774 a and further towards piston and cartridge chamber wall opening 785 .
  • electrical contact between wiper contacts 774 c and 774 b is present until layer edge 784 b is encountered.
  • FIG. 7 p depicts inner application arm assembly 701 d from a bottom view without a piston installed, thus providing a view of application and on-demand heating module wiring cable 770 c and connector 770 b which may be connected to application and on-demand heating module connector 770 a of circuit board assembly 767 of FIG. 7 k .
  • wiring cable 770 c is additionally connected to a spring loaded connector block 770 e by a connector 770 d, which collectively provide electrical connection to heating and distribution plate electrical interface 746 of heating and distribution plate 740 of application and on-demand heating module 707 ( FIG. 7 e ).
  • FIG. 7 p additionally shows retraction arm slot 787 though which retraction arm 783 ( FIG. 7 l ) may pass and along which retraction arm 783 may travel both during a retraction of piston 715 and an application of product.
  • FIG. 7 p additionally shows tape 786 b, 786 c and 786 c which secures and maintains a location for cables 770 c and 772 c.
  • a user retracts piston 715 by moving piston retraction lever 704 towards the pivot cap 703 end of the application arm 701 , if not already positioned there.
  • the user then releases locking recesses 737 of clip 736 of application and on-demand heating module 707 from clip latches 739 and pivots the clip 736 and module 707 upward, pivoting on mounting tabs 749 .
  • the user then inserts into piston and cartridge chamber 776 , a product cartridge shell assembly 706 , or simply a product cartridge 720 in the case of the configuration of FIG.
  • piston and cartridge chamber 776 comprises an integrated shell 799 .
  • the user then secures clip 736 back to a latched position which causes cartridge access and seal feature of application and on-demand heating module 707 to gain access to product through product outlet 723 and seal of product cartridge 720 , and seal thereto, and permit product flow into inlet 742 of product distribution and heating plate 740 .
  • the user then positions switch 709 to an “on” position, thereby causing power from batteries 764 to be supplied to circuitry residing on circuit board assembly 767 .
  • LED indicator 710 may indicate a warning that no available product is present by, for example, emitting a flashing red color of light.
  • LED indicator 710 may indicate a favorable apparatus status, such as by first emitting one, two or three flashes of green light to indicate a target temperature of low, medium or high, respectively, as read from readable target temperature indicator 726 or as indicated by a position of switch 709 , followed by a non-flashing color of green.
  • a user may previously have moved or may now move opposing manipulator 708 to a manipulation orientation 708 a.
  • a user may press piston release bar 705 thereby disengaging brake pad 795 ratchet surface from piston control arm 716 ratchet surface, allowing piston 715 to move towards piston and cartridge chamber 776 and transfer force from spring 780 to collapsible reservoir 721 generating pressure therein and causing product to flow out of reservoir 721 and into inlet 742 and distribution channel 741 of product distribution and heating plate 740 .
  • a resistance level indicating a temperature below a target level as indicated by a position of switch 709 or a readable target temperature indicated by indicator 726 is registered by circuitry of circuit board assembly 767 which then supplies power from batteries 764 to heating element 745 until such time that the target temperature is achieved.
  • Power is applied to heating element 745 in proportion to the negative delta between the measured temperature indicated by thermistor 750 and the target temperature, wherein negative delta means the amount by which the measured temperature is lower than the target temperature. Any time a zero or positive delta is encountered, no power is applied.
  • Retraction lever 704 will traverse a slot (not visible) in application arm 701 as product in product cartridge 720 is being depleted and piston 715 and piston control arm 716 , to which it is attached via retraction arm 783 , advance position within piston and cartridge chamber 776 .
  • the slot can be appropriately marked to provide a user with a convenient indication of remaining product.
  • Apparatus 700 may additionally comprise a remaining product level sensor which can provide one or more additional indications such as indicating remaining product is at a low amount or product is fully depleted.

  • Each embodiment generally comprises an applicator, a manipulator and a can receive a provision of product and is configured to enable a user to concurrently apply product and style or otherwise manipulate their hair.
  • Some embodiments comprise product delivery systems which use pressure to generate product flow, some embodiments comprise product delivery systems which use gravitational forces to deliver product flow, and one illustrative embodiment uses both pressure and gravitational forces to generate product flow.
  • Illustrative embodiments of pressure based product delivery systems are disclosed herein which comprise mechanical pumps, both air and airless, electrical pumps and spring driven pistons.
  • Some illustrative embodiments disclosed herein comprise an internal heating system and some illustrative embodiments support a heating of product in a microwave oven or in a heated liquid bath, or other forms of external heating of product.
  • Illustrative embodiments disclosed may receive a provision or volume of product in a variety of ways comprising in a housing, in a reservoir and in a cartridge, the latter of which may be a user filled cartridge, or may be a prepackaged cartridge, and all can be generally referred to as comprising or receiving a volume of product in a product vessel. Disclosure of additional material which may be further explanatory and illustrative and relate to one or more of the foregoing detailed disclosed embodiments is now provided.
  • Holes or openings, and patterns thereof, in an applicator surface can be varied to vary the rate of flow of product therethrough.
  • applicators will generally require larger applicator openings than in embodiments where product flows primarily due to applied pressure, such as pressure applied from a pump or a piston, as described in apparatus 300 , 500 , 700 and 800 , which comprise pressure driven systems.
  • the viscosity of product varies considerably from light oils to heavy oils to creams and softened butters. Heating product produces additional variations in product viscosities.
  • Fluid flow in a gravity system is primarily dependent on product viscosity and a compromise in a suitable opening size and pattern must be found to accommodate a range of product viscosities and resulting range of flow rates. Furthermore, gravity systems may be less effective for use with high viscosity products than with low viscosity products, and not suitable for use with softened butters and thick creams.
  • fluid flow is primarily dependent not on the viscosity of the product, but rather the specific gravity of the product, which is relatively consistent across types of product.
  • an opening geometry can be chosen which minimizes leaking of the product by way of a mechanism of surface tension across the opening, yet provides optimal flow under pressure for a wide range of product viscosities.
  • Electric pump systems can be envisioned that work directly on the product, namely, the product moves through the electric pump, as opposed to the system of apparatus 500 where the electric pump moves air to a reservoir to provide pressure to generate product flow.
  • an inline flow sensor can be configured to provide for a measurement of and regulation of flow of product.
  • Such systems could include a user controllable variable flow rate control.
  • the electric pump will reside between the product vessel and the applicator, and an application and on-demand heating module is preferably used to heat product, such as that used in embodiments 700 and 800 .
  • a less desirable alternative of heated product being pumped from a reservoir allows for the product to cool as it is pumped through the system, and anytime the system is paused between user applications of product, the product is allowed to cool further.
  • the flow rate may be controlled by varying the aperture of the applicator openings.
  • a shutter comprising an appropriate pattern of openings could be positioned behind and against the applicator pattern of openings and be operatively coupled to an actuator button that operates against a spring to slide the shutter and release the shutter to slide back, thereby varying apertures of the applicator openings through a range from completely closed to completely opened to control the product flow rate from a rate of zero flow to a rate of maximum flow, respectively.
  • applicators and user selectable options thereof can comprise manipulators which can comprise openings for product flow.
  • teeth manipulators can be hollow providing a piping action from the applicator surface to surfaces of the teeth, such as the sides or tips of the teeth or both.
  • An apparatus comprising an applicator and opposing manipulator such as 500 , 700 and 800 may be configured to use applicator manipulators and opposing manipulators which are interchangeable. When so configured, a reduction in unique parts to be manufactured, inventoried and distributed may be achieved by the manufacturer and product distributors, and the user of an apparatus may have fewer unique parts to purchase and manage while still achieving a higher degree of configurability.
  • At least one manipulator on an apparatus should serve to detangle and comb or brush hair in order to efficiently distribute and apply product as well as style and manipulate hair.
  • a plurality of teeth, bristles, fins or other such protruding structures capable of passing through strands of hair are needed on at least one manipulator on the apparatus.
  • a manipulator useful for sectioning hair wherein sectioning hair generally means parting hair and defining a section of hair for current attention of the hair care process, may be useful.
  • an additional manipulator comprising a single or lesser number of protruding structures may be useful to section hair.
  • a user of an apparatus comprising an applicator and opposing manipulator such as 500 , 700 and 800 may find their particular hair characteristics are best managed by using a broadly spaced, large tooth manipulator geometry comprised by an applicator, and a tightly spaced, finer bristle on an opposing manipulator module.
  • the user may find that the large tooth applicator manipulator can be favored when detangling and applying an initial application of product, and a tighter closure of the clamp and a combined emphasis of both manipulators is expeditious to distribution of product and finer manipulation of a section of hair once detangled and an initial application of product is disposed thereon.
  • Alternative embodiments for apparatus similar to apparatus 700 and apparatus 800 can be considered, wherein lower cost alternative embodiments are manufactured and marketed which comprise fewer electrical components or do not comprise any electrical components.
  • application and on-demand heating modules can be alternatively configured as non-heating applicators and product cartridges can be manufactured to support alternative heating in a microwave oven or liquid bath, and optionally comprise a thermochromatic device or material to indicate a temperature that is both safe for hair health and enhanced absorption by hair is present.
  • an external cartridge heater which can receive a plurality of cartridges and run off wall power can be provided.
  • lower cost prepackaged product can be achieved by configuring the cartridge shell to additionally comprise the rigid dispensing end, such that the prepackaged product is simply a collapsible product reservoir, which can also be called a collapsible product vessel or be referred to as the product cartridge, and is filled with a volume of product.
  • the cartridge shell comprising the rigid dispensing end can be reused to lower the total cost of use of the apparatus and consumables including prepackaged product cartridges, and when an external heating source is used, the reusable cartridge shell comprising the rigid dispensing end can further optionally comprise a thermochromatic device or material to indicate a temperature that is both safe for hair health and enhanced absorption by hair is present.
