DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In FIGS. 1 to 29 of the accompanying drawings there is schematically depicted is an applicator 10 to apply liquid 32 to hair. For example, the liquid 32 may be a dye or other hair treatment liquid. In this embodiment, the applicator 10 includes a handle 11 that is hollow so as to provide a chamber 12 to store the liquid 32 that is to be delivered to the hair. The handle 11 includes a longitudinal side wall 13 which for example may be cylindrical in configuration. In one embodiment the side wall 13 is generally rigid, while in another embodiment the side wall 13 is resiliently deformable so that a user gripping the handle 11 may resiliently deform the wall 13 to apply pressure to the liquid 32 within the chamber 12. The handle 11 has a longitudinal axis 14.
Fixed to an end wall 15 of the handle 11 is a stem 16. The stem 16 is substantially rigid and may be formed integrally with or merely attached to the handle 11. As an example the handle 11 and stem 16 may be integrally fouled from plastics material.
The stem 16 has a longitudinal axis 17, which in this embodiment is aligned with the axis 14. The stem 16 has a plurality of transverse grooves 18.
Extending outwardly from and fixed to the stem 16 is a plurality of teeth 19 spaced so that hair may pass therebetween. In this embodiment the teeth 19 extend generally radially relative to the axis 17 so as to extend away from the stem 16.
The stem 16 is hollow so as to provide a longitudinal passage 20, the passage 20 communicating with the chamber 12 so that the liquid 32 may pass from the chamber 12 and move longitudinally of the stem 16 via the passage 20. The stem 16 has a generally cylindrical longitudinal wall 21 that may be formed integral with the handle 11 or alternatively (as shown in FIG. 4) threadably engaged with the wall 13 so as to be fixed thereto.
The stem 16 is provided with a socket 22 that is in communication with the passage 20. Releasably secured in the socket 22 is an applicator portion 23.
The applicator portion 23 is formed of resilient material (such as natural or synthetic rubber or plastics).
The portion 23 includes a base 24 within which there is formed a plurality of ducts 25. The ducts 25 may be square, rectangular or of any desired transverse cross-section. The ducts 25 extend transversely through the base 24 so as to provide for liquid flow between the passage 20 and apertures 26 formed in the surface. In this embodiment the apertures 26 are narrow elongated slits aligned generally parallel to the axis 17. The base 24 is also formed with a plurality of teeth 27 between which the apertures 26 longitudinally extend.
In a modification of the applicator of FIGS. 1 and 2, the stem 16 may be provided with a longitudinally extending heating element 28, with the handle 11 being provided with a switch via which electric power is delivered to the element 28. Typically a regulating device would govern the operating temperature of the element 28.
In a modification of the applicator of FIGS. 1 and 2, the teeth 19 can be replaced with a bar 29 to aid in retaining the hair against the stem 16 so that liquid may be applied thereto. In this embodiment, the bar 29 has its longitudinal direction of extension along the stem 16, and is preferably pivotably attached to the stem 16 by means of a pivot assembly 30. The spring loaded pivot assembly 30 provides a pivoting axis for the bar 29 that is transverse of the stem 16, that is generally perpendicular to the axis 17. A trigger 31 is fixed to the bar 29 and is engaged by a user's finger to cause angular movement of the bar 29 in the direction of the arrow 32. The assembly 30 urges the bar 29 towards the stem 16. The bar 29 may be electrically heated.
Preferably, the side wall 20 has an aperture 33 via which air may enter the passage 20 and therefore the chamber 12 to aid in equalising pressure within the chamber 12 relative to atmospheric pressure.
In FIG. 17 there is schematically depicted a modification of the applicator portion 23. In this embodiment the base 24 has a surface 34 over which the hair is drawn to apply the liquid thereto. The surface 34 has an elongated aperture in the form of a slot 35 that extends substantially the entire length of the base 24 and is generally parallel to the longitudinal axis 17. The slot 35 communicates with a passage 36 that again extends substantially the entire length of the base 24.
In the embodiment of FIG. 18, the surface 34 is a plurality of apertures in the form of slots 37 that communicate with the passage 36. The slots 37 are aligned so as to extend longitudinally and generally parallel to the longitudinal axis 17.
In the embodiment of FIGS. 17 to 20, again the base 24 is formed of resilient material so that the slot 35 or slots 37 are resiliently urged to close, and are moved to an open position by movement of hair across the surface 34.
In FIG. 21 there is schematically depicted a modification of the applicator portion 23. In this embodiment the applicator portion 23 includes edge portions 38 that are in the form of “lips” and are fixed to the surfaces 34 and project therefrom away from the longitudinal axis 14. The edge portions 34 aid in engaging the hair to cause resilient deformation of the insert 34 to open the slot 35 and slots 37. In the embodiment of FIG. 22 two edge portions 38 are provided that are generally parallel and co-extensive and located on opposite sides of the associated slot 37. The edge portions 38 would aid in engaging hair irrespective of the direction of movement of the hair over the surface 34.
In the embodiment of FIG. 22, only a single edge portion 38 is provided for each slit 37.
In the embodiments of FIGS. 21 and 22, the applicator portion 23, in transverse cross-section, is “U” shaped in configuration. It has two generally parallel and co-extensive side walls 39 joined by a transverse base 40 that has the slot 35 or slots 37 and that provides the surface 34. A hollow 41 communicates with the passage 20 so that the liquid is delivered to the slot 35 or slots 37. The walls 34 are received within the socket 22 and frictionally engage the sides thereof to retain the applicator portion 23 secured to the stem 16.
As best seen in FIG. 16, a user grips the handle 11 and causes hair to curl about the stem 16 and then moves the applicator 10 so that hair passes over the surface 34. In the embodiment of FIG. 1, the hair also passes between the teeth 27, with the hair being forced to pass about the stem 16 by the teeth 26 and 19 or the bar 29. Hair passing between the teeth 27 engages the applicator portion 23 causing resilient deformation thereof so as to urge the apertures 26 to open. Prior to this the resilient material from which the portion 23 is formed, urges the apertures 26 to a closed configuration.
In the embodiment of FIGS. 23 to 29, the applicator 10 is modified so that included in the handle 11 is a battery operated motor 42 that receives electric power from batteries located in a battery compartment 43. Located in the passage 20 is a driven member 44 which in this embodiment is a spiral screw member 45 that extends angularly about and longitudinally of the axis 17. The driven member 44 is drivingly attached to the motor 42 so that upon rotation of the driven member 44 about the axis 17 the liquid 32 is caused to flow to the apertures 26. In that regard the handle 11 may be provided with Is an aperture 46 that provides for the venting of air to the passage 20. In an alternative embodiment, the passage 46 may be attached to a flexible tube 47 that extends to a reservoir of the liquid 32. Accordingly upon operation of the motor 42, liquid 32 would be drawn from the reservoir (not depicted) and delivered to the passage 20 from where it flows to the apertures 26. Typically the handle 11 would be provided with a button or trigger used by an operator to deliver electric power from the batteries to the motor 42.
In this embodiment the applicator portion 23 is elongated longitudinally in the direction of the axis 17, while each of the apertures 26 is a slit that extends generally transverse of the applicator portion 23, that is generally transverse relative to the axis 17.
In this embodiment the base 24 provides a pair of generally parallel flanges 48 between which there is a slot 49 that engages the wall 21 so that the wall 21 projects into the slot 49.
The surface 34 is provided by a pair of converging sub-surfaces 50 that converge away from the base 24 to a longitudinally extending peak 51.
The apertures 26 communicate with the passage 20 by means of an elongated cavity 52 formed in the base 24.
Again the applicator portion 23 is formed of resilient material so that upon hair engaging one or both of the sub-surfaces 50, the applicator portion 23 resiliently deforms to open the apertures 26 to enable hair to enter and/or for liquid to exit.
In the embodiment of FIGS. 30 and 31 there is schematically depicted an applicator 60 to apply a liquid 61 to hair. The applicator 60 includes a stem 62 that is hollow so as to provide a passage 63 that receives the liquid 61. One end of the stem 62 is provided with a socket 64 that receives an applicator portion 65 that may be identical to any one of the applicator portions 23 previously described. Preferably in this embodiment the applicator portion 65 is identical to the applicator portion 23 of FIGS. 24 to 29. Accordingly it has converging surfaces 50 and apertures 26 in the form of transverse slits that extend generally transverse of the applicator portion 65. As is best seen in FIG. 30, the applicator portion 65 is longitudinally elongated. In accordance with FIG. 25, the applicator portion 65 has a cavity 52 providing for liquid communication between the passage 63 and the apertures 26.
Preferably, the stem 62 is formed of deformable material so that the passage 63 may be deformed and thus reduced in volume to cause liquid 61 to flow along the stem 62 to the apertures 26. Deformation of the stem 62 would be caused by a user gripping the stem 62 and compressing the stem 62. More preferably the stem 62 is formed of resiliently deformable material. Preferably the passage 63 is closed apart from the apertures 26.
In the embodiment of FIGS. 32 and 33, the applicator 60 is provided with a comb member 66 fixed to the stein 62 and providing a plurality of teeth 67 through which hair would be drawn to pass over one or both of the surfaces 50 to cause resilient deformation of the applicator portion 65 and therefore opening of the apertures 26 so that hair may enter the apertures 26 and/or liquid to exit the apertures 26. In this embodiment the user grips the stem 62 to move the applicator 60 along a length of hair. The apertures 26 may extend transverse or parallel to the longitudinal axis 68 of the applicator portion 65.
In the embodiment of FIG. 34, the applicator 70 has a stem 72 including a generally arcuate body 71 having longitudinally extending edge portions 73. Applied to and secured to the edge portion 73 is a flexible resilient applicator portion 74. The applicator portion 74 has longitudinally extending flanges 75 with longitudinally extending slots 76 within which the edge portion 73 are located so that the applicator portion 74 is fixed to the stem 73. Extending from the flanges 73 is an apex portion 77 having sides 78 that converge from the flanges 75 to an apex 79. Typically slits (apertures) would extend from the apex 76, through the applicator portion 74 to communicate with the passage 80 to which the liquid to be applied is delivered. Fixed to or formed integral with the body 71 are teeth 81.
In FIGS. 35 to 39 there is schematically depicted an applicator 90. The applicator 90 is to apply liquid to hair as previously described. The applicator 90 includes a handle 91 that is hollow so as to provide a chamber 92 that stores the liquid to be delivered to the hair. The handle 91 includes a longitudinal extending side wall 93 that would be typically of a cylindrical configuration. In one embodiment the side wall 93 is rigid while in another embodiment the side wall 93 is resiliently deformable so that the liquid contained in the chamber 93 may be caused to pass through the hollow stem 96. The stem 96 is attached to an end wall 95 of the handle 91. The handle 91 and stem 96 have a longitudinal axis 94. The stem is substantially rigid.
Attached to or formed integral with the stem 96 (so as to be attached thereto) is a plurality of comb teeth 97 between which a user's hair may pass.
The stem 96 is hollow so as to have a longitudinally extending passage 98 to which the liquid is delivered from the chamber 92.
The stem 96 has a longitudinally extending aperture 99 defined between longitudinally extending edges 100 of the stem 96. Engaged with the edges 100 so as to close the aperture 99 is an applicator portion 101. The portion 101 is preferably formed of resilient material and is generally concave so as to provide a cavity 102 that receives the liquid from the passage 98.
The applicator portion 101 has an arcuate body 103 from which there extends a peaked longitudinally extending projection 104 with transverse slits 105. The slits 105 communicate with the cavity 102 so that liquid may exit via the slits 105 upon pressure being applied to the portion 101 to cause resilient deformation thereof to at least partly open the slits 105 so that the liquid may pass therethrough.
The end of the stem 96 is closed by a cap 106 to thereby close the extremity of the passage 98.
In use of the above described applicator 90, hair passing over the surface 107 of the portion 101 and through the slits 105 to cause the slits 105 to open to provide s apertures via which the liquid may pass from the passage 98, through the cavity 102 to exit to be applied to the hair. As the portion 101 is formed of resilient material, the slits 105 are urged to a closed position.
The edge portions 100, together with the aperture 99, provide a socket to which the applicator portion 101 is applied.
The portion 104 provides the surface 107 within which the slits 105 are formed. The surface 107 faces away from the stem 96 in the predetermined direction 108. The comb-teeth 97 also project away from the stem 96, preferably having a major direction of extension generally normal to the axis 94.
In respect of the above described preferred embodiments it should be appreciated the applicators 10, 70 and 90 are intended to be moved angularly about their respective longitudinal axis 14, 94 and/or past in a wiping action along a length of hair. More particularly, as is best described with reference to FIG. 16, the hair is moved arcuately about the surface containing the apertures 26, 105. In the embodiments of FIGS. 30 to 33, the applicator 60 is intended to be moved along a length of hair in a wiping action. In doing so a user grips the stem 61.
