Definitions

  • the present invention relates to cosmetic treatment of hair.
  • the invention relates to an apparatus and method for applying a chemical such as dye or bleach to human or animal hair.
  • Chemical treatment of human or animal hair for example by highlighting, low lighting or bleaching, is traditionally performed by separating individual locks of hair, placing aluminum foil under each lock, applying hair dye or other chemical to the locks and wrapping the foil around each lock to temporarily seal in the chemical. When properly performed, this method allows the chemical to contact the hair for a prolonged period to treat the hair.
  • An alternative treatment involves the use of a plastic masking sheet, such as that described in UK patent no. GB 2426447 and United States Patent No. 5,287,864.
  • the masking sheet is generally rectangular with a pressure sensitive contact adhesive along one edge.
  • a lock of hair can be placed on the sheet and adheres to the selected adhesive.
  • a chemical is applied to the hair, normally in the form of a paste or other viscous formulation.
  • the sheet is then folded over to cover the lock of hair and the adhesive layer retains the sheet in the folded over position with the treated lock of hair sandwiched between the two layers of the sheet.
  • the folded structure is open at the sides. Unless carefully performed, the chemical can escape from the sides of the structure and the device can dislodge from the hair with movement.
  • An objective of the present invention is to provide an improved method and apparatus for applying a chemical treatment to hair.
  • One aspect of the invention relates to a device for applying a chemical to a lock of hair.
  • the device comprises:
  • a sheet comprising an impervious material, said sheet comprising lateral edges, a top edge and a bottom edge and being configured to be folded along a transverse axis to form an envelope configuration for retaining a lock of hair and a dose of hair treatment chemical between opposing portions of said sheet, and
  • a lock of hair may be engaged within the interior of said envelope for treatment by a chemical retained within said envelope and whereby when unfastened said lock of hair may be released from said envelope.
  • the fastener is adapted to retain the lock of hair to the sheet.
  • the fastener may further include a clip for fastening said lock of hair to said sheet prior to folding said sheet into said envelope configuration.
  • the clip may be adjacent to an upper edge of said sheet.
  • the invention relates to a method for applying a chemical to a lock of hair, comprising:
  • the method may comprise the further step of gripping the lock of hair with an openable clip prior to folding said sheet, and opening said clip to release said lock upon completion of said chemical application.

  • Figures 1A to 2B illustrate a first embodiment of a device 100 for applying a chemical to a lock of hair 102 according to the invention.
  • Device 100 comprises a foldable sheet 104 of material.
  • Sheet 104 is rectangular and comprises lateral sides 10 and 12 and upper and lower edges 14 and 16.
  • Sheet 104 comprises a transparent or translucent material that is impervious to hair treatment chemicals.
  • the material comprises a flexible plastic such as plastic.
  • a suitable plastic can be almost any type that is unaffected by conventional hair treatment chemicals, which in general are not significantly reactive since such chemicals must not attack the hair or scalp of the user. As such,
  • sheet 104 may fall within a broad range; for example, 4 to 10 mils provide a suitable range of thickness for sheet 104.
  • Sheet 104 is symmetrical about a midline 106 that extends along a transverse axis joining lateral sides 10 and 12 of sheet 104.
  • Midline 106 may be defined visually by a visible marking, or it may comprise a region of thinner material to facilitate folding, or it may comprise a virtual line.
  • a visual cue of the location of midline 106 is provided to make it easy for the user to fold sheet 104 at the midline.
  • Sheet 104 defines identical opposing regions 20 and 22 on either side thereof. Region 20 comprises an upper region and region 22 is a lower region when the sheet is vertical, with midline 106 being horizontal. While in the present example sheet 104 is rectangular and is evenly bisected by midline 106, sheet 104 may also comprise other shapes that may be conveniently folded to form an envelope, as described below; as well, midline 106 need not be located precisely midway between upper and lower edges but may be offset from this location whereby a portion of upper region 20 protrudes above lower region 22 when the sheet is upright. Sheet 104 may have a surface suitable for marking, for example to provide directions to users or to allow a user to indicate the chemical that is in use or the time for removing the device. Preferably, the surface permits an erasable form of marking to be applied. As well, the device is preferably washable and reusable.
  • Sheet 104 can comprise a broad range of sizes depending on the desired application . In one aspect, sheet 104 ranges from 6 cm to 9 cm in width, preferably about 7.5 cm and from about 10 cm to about 18 cm, preferably about 15 cm in length . However, the dimensions and configuration of the device may vary considerably.
  • Sheet 104 can be folded in on itself along midline 106 to form an envelope configuration composed of upper and lower opposing portions 20 and 22 of sheet 104.
  • midline 106 forms a sealed edge of device 100, and the remaining three sides are initially open.
  • the lateral sides 10 and 12 are then fastened together by hook-and-loop fasteners 112 and 114; it will be seen that other fasteners or fastening means may be employed to fasten the respective portions together along or adjacent to lateral sides 10 and 12.
  • fasteners 112 and 114 are releasable whereby they may be readily pulled apart or otherwise released to unfold sheet 104 to release the lock of hair.
  • fasteners 112 and 114 When fastened, fasteners 112 and 114 close the opposing sides of sheet 104 along lateral sides 10 and 12. Since hair treatment chemicals that are typically used with the device are usually in the form of a paste, it is not necessary for the closure to be fully sealed, provided that it is sufficient leak-proof to prevent or substantially prevent leakage of paste.
  • Additional fastener portions 25 and 27 are provided adjacent to upper and lower edges 14 and 16 respectively.
  • Fastener 25 located on upper edge 14 is the hook portion of the fastener, which serves to grip a lock of hair that is pressed against fastener 25. This allows the user to temporarily retain the device in the open position to the lock of hair, whereby the sheet is held in an open position to the lock of hair.
  • sheet 104 When sheet 104 is folded in half and the respective fasteners are fastened along the lateral and upper/lower edges, sheet 104 forms an essentially fully enclosed envelope structure that is substantially closed along all four sides.
  • Fasteners 25 and 27 retain edges 14 and 16 together to grip the user's hair for secure retention with the interior of sheet 104, as folded into an envelope.
  • fasteners 112, 114, 25 and 27 comprise strips arranged around the periphery of sheet 104 and that may range in width from about 1 cm to 3 cm and preferably are about 2 cm in width. The respective fastener strips surround an uncovered region
  • region 30 of sheet 104 When sheet 104 is folded in half, region 30 provides a pocket that retains the lock of hair and the hair treatment chemical, as described below.
  • hook and loop fasteners 112 and 114 may be replaced with other releasable fasteners or fastening means that provide a similar function of fastening the opposing portions of sheet 104 together for forming an envelope.
  • the fasteners may also serve to engage a lock of the user's hair to the envelope to permit the user to apply a chemical while the envelope is open.
  • Suitable fastening means include, without limitation, mechanical fastening means such as hook and loop fasteners as described above or zipper-type fasteners, as well as non-mechanical fasteners such as magnetic fastening means or other substances that engage on contact and readily disengage by peeling apart, and which are suitable for repeated use and are relatively unaffected by contamination.
  • the latter types of mechanical fasteners may not provide the second function of retaining the user's hair, and can be used in conjunction with a clip or other means to retain the user's hair to the envelope prior to closing the envelope.
  • sheet 104 may comprise a rigid material that is hinged along midline 106.
  • the opposing portions of the sheet are spaced apart when folded so as to form an interior space at central region 30 within the envelope to accommodate the lock of hair and hair treatment chemical.
  • the fasteners may serve to space apart the respective portions of the sheet in this embodiment.
  • Corner regions 116 of sheet 104 are uncovered by fasteners 112 and 114. This feature permits opposing layers of sheet 104 to be easily separated at corner regions 116, to allow a user to separate the respective layers to open the device from the closed position. Corner regions may comprise recessed portions of fasteners 112 and 114, as seen in Figures 1A and I B. Alternatively, corner regions 116A may comprise projecting tabs that extend outwardly from sheet 104, as seen in Figures 2A and 2B.
  • a lock of hair 102 is placed on sheet 104 with the device 100 in an open (unfolded) position, as in Figure 1A.
  • Contacting the hair with fastener 112 temporarily engages the device 100 to the lock of hair and holds the device, in an open position, to the hair without the need to hold device 100 in place by hand.
  • a dose of a hair treatment chemical is then applied to the lock of hair 102.
  • the chemical may comprise any substance suitable for treating hair.
  • the term "chemical” as used herein is not restricted to a chemical compound, but is used broadly to include without limitation individual compounds, compositions, mixtures, colloids, and emulsions.
  • the chemical may be in any form or phase that permits application to hair, such as a paste, cream, gel, foam or liquid.
  • the chemical may also be in the form of a powder or other solid phase.
  • the chemical comprises a liquid that is relatively viscous to minimize leakage, and which the user can work into the hair before closing the device. Examples include hair dyes, bleaches, lighteners and darkeners.
  • the chemical may be applied by any suitable means including without limitation brushing, spraying, dripping or any other suitable means of application. Alternatively, a lock of hair may be dipped in a bath of the chemical prior to placement on sheet 104.
  • sheet 104 is closed to form a substantially sealed and leak-proof envelope around the lock to allow for an extended period of contact with the chemical.
  • sheet 104 is formed into an envelope by folding along the midline 106 and engaging fasteners 112 and 114.
  • fasteners 25 and 27 are engaged to close the upper and lower edges 14 and 16 of sheet 104 together to thereby form a substantially sealed envelope wherein the only openings are where the lock of hair 102 enters the envelope, as seen in Figure IB.
  • a benefit of the use of a transparent or translucent material for sheet 104 is that a user can visually check the effect on his or her hair without opening the closed device 100.
  • FIGS 3A-4B illustrate a second embodiment of device 200.
  • Device 200 comprises a sheet 104 and fasteners 212 and 214 similar to the first embodiment.
  • a hair clip 208 is secured to a top edge 14 of the sheet 204.
  • Clip 208 comprises any suitable clip that may be opened to receive a lock of hair and closed to securely retain the lock by friction and/or a forming a contorted path for the hair.
  • clip 208 comprises a U- shaped resilient member composed of opposing arms 240 and 242 joined by a bridge 244 at one end. Bridge 244 resiliently biases arms 240 and 242 towards an open position.
  • Second arm 240 terminates in a U-shaped retainer 246.
  • the first arm 242 is configured to slip under retainer 246 to be retained in the closed position, wherein the resilient biasing urges first arm 242 upwardly against the underside of retainer 246 to be held in the closed position.
  • arms 240 and 242 are spaced to tightly grip a lock of hair.
  • Arms 240 and 242 may be coated with a material having a high coefficient of friction to improve the frictional grip on a lock of hair when clamped onto the lock.
  • Clip 208 can be either removable from the sheet or permanently fastened on the sheet 104.
  • Clip 208 can be fastened to sheet 104 by a sleeve 248 adjacent to upper edge 14 of sheet 104. First arm 240 slides into the sleeve to be retained thereby.
  • An alternative means to fasten clip 208 to sheet 104 is to provide clip 208 with sufficient length to exceed the width of sheet 104, which permits the user to close clip 208 on a portion of sheet 104 adjacent its upper edge 14, along with a lock of hair.
  • the protruding portion can also be provided with the sleeve configuration described above.
  • clip 208 and sheet 204 are initially both placed in the open position and a lock of hair is placed on sheet 104 between arms 240 of 242 of clip 208.
  • Clip 208 is them closed to secure hair 202, as seen in Figure 3A.
  • the chemical is then applied to the lock of hair 202 as in the first embodiment and sheet 204 is folded over on itself to form an envelope that encloses the lock of hair.
  • Sheet 204 is then sealed along its periphery with fasteners 212 and 214 to retain the chemical within the envelope interior for prolonged contact with hair 202, as seen in Figure 3B. Corner regions 216, 216A uncovered by fastener material are provided as in the first embodiment to permit opening of the device.
