Hair Styling Tool
A hair styling tool comprises a central roller (12) having end pieces (14) disposed around the outside of the roller and in which the outside surface (16) of the roller between the end pieces (14) has one or more dividers to form two or more segments (18,19) around the roller. In specific arrangements the roller is hollow and certain segments (19) have holes (30) through which hair treatment may be forced.
The present invention relates to a hair styling tool. Although arising from the application of dye to selectively colour or highlight hair, the invention can be used to differentially apply bleach, perm lotion, conditioners and other treatments to part of the hair, while reducing the risk of the treatment straying to other portions of hair which are to remain untreated.
Applying coloured highlights to hair is a highly skilled and labour intensive task, typically taking between sixty and ninety minutes per client. Two methods are currently in common use.
The first method, commonly used in professional hair salons, requires the manual segregation of hair into areas to be coloured and areas not to be coloured followed by the manual application of dye while protecting the rest of the hair using, for example, aluminium foil. This method is time consuming, taking between sixty and ninety minutes per client, making it expensive; it can also produce uneven results as the hair treated first will be exposed to the dye for up to 90 minutes longer than the hair treated last. The segregation of hair into coloured and uncoloured portions and the subsequent application of dye is also a highly skilled task adding to the cost of the process.
The second method, more commonly used by amateurs utilises a close fitting cap, for example, made of latex pierced in numerous places with small holes through which the hair to be coloured can be pulled using a small hook. Both methods have a number of deficiencies. This method is also time consuming and can produce undesirable results due to the random nature of the colour distribution as it is not possible to select specific portions of hair to be coloured.
Various proposals have been put forward in an attempt to solve the problem of speed and skill required, but with only limited success. Devices described in U.S. Pat. Nos. 5,588,449 and 7,530,358 are complex with many moving parts giving only a modest improvement in speed and reduction in the skill required while introducing equipment that would be expensive and difficult to clean. The devices of U.S. Pat. Nos. 6,145,513 and 6,286,518, while improving the speed of operation but are limited in accuracy, only work effectively with viscous colouring products and expose the clients scalp to chemicals in the colouring process.
In this invention the expression “hair treatment” covers bleaches, dyes, perm-lotions, conditioners and as well as other treatments. “Liquid hair treatments” are such treatments provided as a liquid, suspension in a liquid, or dissolved in a liquid. Viscosity is immaterial beyond a requirement that the liquid will flow in the devices described herein.
In this invention the expression “basic hair treatment” covers all of the types of hair treatment as described previously above in paragraph [0006] but where the chemical (s) or treatment is present in a substantially dry form such as powder, granule, tablet or other such composition including gases or vapour. “Basic hair treatments” are such treatments that substantially dry until a catalyst is added where it then intermixes with the “basic hair treatment” and creates a substance that can flow. Alternatively the “basic hair treatment” can be a combination of both “basic hair treatment and a catalyst” which are brought together but is maintained in an inert form until the introduction of a releasing agent such as a solvent, or oxygen or such other catalyst whereby the “hair treatment” then develops and is applied to the parts of the hair requiring the treatment in the usual way.
According to the present invention a hair styling tool has a roller characterized in that the roller has one or more dividers disposed around its external surface to form two or more segments around the roller, and in that the roller has holes along its length leading from the interior of the roller into one or more of the segments and in that pressure applied to liquid hair treatment urges the liquid hair treatment through the holes from the interior of the roller into the one of more said segments.
The holes are aligned with the segments which will contain hair intended to be treated.
In a first embodiment such a hair styling tool is characterized in having an applicator to urge the liquid hair treatment through the holes from the interior of the roller into the one of more said segments.
Hair can be wound onto the roller between the dividers giving at least two separated portions of hair. The roller can be made of any resilient material, preferably a mouldable polymer such as nylon, polypropylene or polyethylene. The roller can be of any suitable dimension to wind hair onto, but preferably between 10 mm. and 100 mm. Preferably the dividers are movable relative to the roller. Preferably the dividers are shaped so as to at least partially enclose the portion of hair between them. The dividers can be made of any suitable resilient material but preferably a mouldable polymer.
The roller would normally be cylindrical but there is no reason why it should not be of another section—triangular or square for example if special effects are required. An applicator, comprising a plunger and reservoir could then be a corresponding shape to fit the roller.
Normally the dividers are disposed generally perpendicular to the axis of the roller. But in one arrangement the outer portion of the dividers are inclined at an angle to the perpendicular such as to partially protect a portion in a segment of hair from flow over of liquid hair treatment from an adjacent segment.
The dividers 18 and 19 are generally equally spaced along the axis of the roller but there is no reason why they should not be unequally spaced or be of unequal depths depending if special effects are required. Additionally there is no reason why a roller cannot have a combination of different sections and shapes and alternate widths and depths to create variety of effects.
In one embodiment the applicator is a plunger operating within the hollow roller into a container to contain the treatment, the treatment is squeezed out of the container and through an open passage between the plunger and inner surface of the roller though the holes and onto any hair in the segments into which the holes are open.
In a preferred arrangement of the tool with a plunger, the holes connecting with segments towards the ends of the roller are larger than those holes connecting with segments at centre of the roller. The open passage between the plunger and the inner surface of the roller causes resistance to the flow of hair treatment, thus the hair treatment would tend preferentially to flow out of holes towards the middle of the roller. By increasing the size of the holes towards the ends of the rollers, resistance to flow is reduced, thus ensuring more even distribution of the hair treatment along the length of the roller.
In another embodiment the applicator is a container (186) joined to the roller and said container having a plunger, wherein operation of the plunger causes hair treatment to flow through the holes (30) and onto any hair in the segments (19) into which the holes are open. In this embodiment the holes can be equal size, as there is an unrestricted flow within the interior of the roller.
Normally the container would be a pressurised canister containing hair treatment, but in more general terms it can be any arrangement in which pressure is applied to hair treatment in the container to force it into the interior of the roller. The canister can be supplied as a separate unit or as part of the hair treatment tool itself.
In a preferred arrangement of an embodiment having a separate container in which pressure is applied to hair treatment—such as a pressurised canister—the roller is closed at both ends save for an aperture at one end which may be sealed against the outlet of the canister.
The attached figures contain examples of the invention and its use and show further features thereof.
The principles of the invention are described in
In
Optionally the dividers 22 may be moveable in respect to the roller relative to its axis, this is illustrated, for example,
In
Optionally the plunger 32 may have an external screw thread 36 engaging a screw thread on the interior of the roller as shown in
Hair is wound onto roller 12 from the tip of the hair towards the root. The hair segregates itself between the dividers 22 into the segments 18 and 19. When this is done the dividers 22 are flipped by hand to their other stable position, the closed position, enclosing or partially enclosing the hair in segments 19. Hair treatments can be selectively applied to the hair wound onto segments 19, but hair wound onto segments 18 would remain untreated. Pairs of end pieces/dividers, shown as 23 and 24, are inclined in opposite directions to cause partial enclosure of the portions of hair in segments 19. Roller 12 contains a reservoir 28 to contain a suitable liquid hair treatment and holes 30 leading from the interior to the exterior of the roller into segments 19. A plunger 32 faces the reservoir 28 and a channel 36 formed between the reservoir plunger 32, and the inner wall of the roller 12 through to holes 30 between the inside of roller 12 and segments 19. The dividers 22 prevent the hair treatment reaching hair in segments 18.
Minimal assembly is required during manufacture. The roller 12 in this embodiment is a tube moulded from a suitable plastic with several rubber/soft plastic end pieces 14 and dividers 22 that form the segments 18 and 19 when spaced along the axis of the roller 12. As is seen the shape and flexible material of the dividers 22 pieces allows them to be snapped into position in an alternate convex/concave pairs 23 and 24 (as shown in
The stem 44 of plunger 32 and the outer wall of reservoir 28 taper slightly to form the passage 36. The outer part 46 of the stem 44 is parallel sided and is a snug sliding fit within the roller 12; the snug fit prevents treatment escaping along the shaft of plunger 32. The outmost part 48 of reservoir 28 is a tight fit within roller 12 to prevent treatment escaping between the reservoir wall and the inside of roller 12. The reservoir has a cylindrical recess 50 opposite the head 40 of plunger 32 which in turn has longitudinal grooves 42 to allow hair treatment to flow past the plunger head into channel 36.
In use reservoir 28 with prepared liquid hair treatment is inserted into one end 38 of roller 12, plunger 32 is inserted in to the other end 39 of roller 12 (up to a marked position). The roller 12 thus assembled is used in the normal way to roll a chosen section of hair that is to be treated, the conical rubber dividers 22 are flipped in pairs 23 and 24 to form pockets around the divided hair in segments 19, other rollers 12 are used as required over the head of hair. The head 40 of the plunger 32 is pushed into the cylindrical recess 50 to force treatment out through the grooves 42 and passage 36 to holes 30, passing through the holes 30 onto hair in segments 19. The process is repeated with the other rollers in the hair. The rollers are left for the correct period of time as required for the treatment process to be completed before the rollers are removed.
In an alternative to the above the dividers are closed over segment 19 by hand. In one arrangement, the end pieces 14 are fixed but are conical and inclined towards each other. The dividers are conical and flexible as described above. Initially the conical dividers 22 are inclined towards segments 18, with segments 19 open as shown in
Alternatively, rather than pushing the ends of the roller, the ends may be twisted with respect to each other. This causes the roller in its weakened portions 19 to flex forcing the flexible dividers to flip to their other stable position, partially or wholly enclosing the hair within segments 19. Counter twisting or pulling the ends would cause the flexible dividers to flip to their other stable position.
In a further alternative one divider 23, of each pair of dividers 23 and 24, is semi rigid and is inclined towards a segment 19. The other member 24 of the pair is flexible as before. In the open position the divider 24 is inclined towards segment 18. By twisting the roller, this divider 24 is flipped to its closed position inclined towards segment 19 and the other member 23 of its pair. In a similar design to those shown in

The embodiment of
A further embodiment is shown in
The tool has a roller 12 which is a simple one piece moulding. Small hooks located on the outside of surface 16 of roller 12 improve hair grip.
The main components of this embodiment are the same as those shown in
In use the cylindrical recess 50 is filled to the correct level with prepared hair treatment and the reservoir 28 fitted into one end 38 of roller 12. The plunger 32 is inserted into the other end 39 of the roller 12 (up to a marked position) where it engages with the semi flexible lip 86 of the reservoir with the grooves 82 and 84 of the plunger thereby making a seal. Chosen sections of hair to be treated are rolled onto the roller which automatically segregates the hair between segments 18 and 19. Shroud 64 is fitted around the roller 12 to enclose the segregated hair between segments 18 and 19. Other similar rollers are inserted elsewhere in the hair. The reservoir 28 is pushed into the roller 12 and thereby forcing hair treatment out the reservoir 50 through holes 30 into segments 19 depositing treatment onto the hair in those segments. The roller(s) are now left for the correct period of time as required for the hair treatment process to complete before removal of rollers.
In an alternative arrangement, in the embodiment shown in
In
The plunger has a head 40 with grooves 42, stem 44 and parallel sided end portion 46 as before. However, in this case the parallel sided end portion 46 of plunger 32 is engaged within the end 39 of roller 12. The engagement may either be by semi-forced fitting so that the plunger can be removed for washing, or permanently by gluing it or friction welding it in place, or by designing the plunger and roller as a single moulding.
This arrangement can be used with a disposable reservoir as described in
Initially the reservoir 28 is stood on end with cylindrical recess 50 upper-most. If seal 51 is in place, it is removed and the tool 10 assembled by engaging the reservoir 28 partially into end 38 of the roller 12, so that groove 82 is engaged with lip 86 maintaining the roller upright. Hair can now be wound around the roller, separating into segments 18 and 19 as previously described. The gripping means 62 helps maintain hair in position on the roller while shroud 64 (not shown in
The reservoir is described having a refillable cylindrical recess, but there is no reason why it should not be designed to receive a deformable container pre-filled with hair treatment with the plunger engaging against the container and squeezing out the contents. Perm lotion is particularly interesting in this context as it is an application that could easily be used in the roller and does not need premixing so could be contained in a cylindrical recess.
When the reservoir 28 is inserted into the open end 38 of the hollow roller 12, it is twisted to engage behind internal bayonet lugs 108 close to open end 38 of the roller 12. When the plunger 32 is pushed into the reservoir 28, the reservoir cannot be pushed back off in the process. As alternatives the reservoir can also be held in place by other securing means such as clips, or interacting screw threads. With this modification handling is easier, as the knurled gripping ring is elevated off a surface, making gripping of it easier.
The head 40 of plunger 32 has a separable silicon type rubber piece 110, engaging a hexagonal boss 112 on the end plunger 32. The silicon rubber piece 110 acts, firstly, as a means of gripping on the inside the reservoir 28 to hold the head of the plunger in its initial position 114 within the reservoir (currently about 7 mm deep) and, secondly, the deformable surface of the head 40 encourages the last of the hair treatment out of the reservoir. The boss 112 is hollow allowing access to an overflow chamber 116 within the plunger if the rubber piece 110 is removed. At the shoulder of the rubber piece 110 between its lateral side and its head which in use faces the base 104 of the reservoir there are indents 118 (about 2 mm deep and wide) to efficiently facilitate the flow of hair treatment from reservoir 28 to the grooves 42. The indents 118 are aligned with grooves 42.
Holes 120 in boss 119 of plunger 32 towards the end of the stem 44 away from the head 40 allow any excess hair treatment to escape through them and into the overflow chamber 116 inside plunger 32. This avoids hair treatment escaping out from the roller if the user has mistakenly over filled the reservoir with treatment and the segments containing the hair to be treated is now full and the user continues to exert excess pressure to the plunger.
As the silicon rubber piece 110 is removable, there is access for easy cleaning of any excess hair treatment that has escaped into the overflow chamber 116.
The end of the plunger opposite head 40 has a removable cover 121, which enables further access to the overflow chamber 116 for cleaning purposes.
When the plunger 32 is pushed fully into the reservoir 28 as shown in
The outer and inner surfaces 140 and 142 of shroud 64 are now completely smooth and the inner surface 142 is lined with a rubber type material 144, to close off over the dividers 22 to form the annular segments 18 and 19.
In the arrangement shown in
Other variations that are possible include the coupling of the reservoir and plunger together, prior to assembly of the tool, and blocking off one end of the roller 12, so the reservoir/plunger assembly could be assembled into the roller as single item, after the roller was put into the hair and clipped in place. It is also possible for the plunger to have flat sides and the ends to be castellated to aid gripping of the silicon type rubber piece on the end of the plunger and to aid hair treatment flow past to surface of plunger 32, however, this embodiment requires alignment of the plunger with the roller and can reduce the capacity of the reservoir and the reservoir or the roller has to be bigger to compensate.
Operation of the device can be seen more clearly in
The holes 30C and 30D in the roller that correspond with segments 19C and 19D are of a larger size than the holes corresponding with the holes 30A and 30B corresponding with segments 19A and 19B. The larger holes 30C and 30D allows the hair treatment to enter segments 19C and 19D more easily while the slightly constricting holes 30A and 30B leading to segments 19A and 19B. So when segments 19A and 19B are full the remaining hair treatment will quickly enter segments 19C and 19D. Only once all the chambers are full will any excess hair treatment flow towards the boss 119 with the small holes 120 around its circumference, and the dye travels through the holes 120 in the boss into the internal overflow chamber 116.
Stem 44 has raised portions 123 which distribute the treatment evenly around the inside of the roller and prevent it gravitating towards the bottom of the roller.
In a further embodiment, not shown, the plunger head 40 has one or more flat sides, or indeed, or is hexagonal in cross section. The inside of the reservoir would be correspondingly shaped. Castellations may be provided around the lip 86 of the reservoir which nest with corresponding castellations at the transition between the head 40 and stem 44. Such an arrangement may help to align the longitudinal grooves 42 with those on the head 118 and accordingly with corresponding outlets in the reservoir, but is more difficult to set up.

In the examples shown above, basic hair treatment material can also be in the form of a powder, granule, gel, a tablet or the like or contained within a dissolvable capsule or in a dissolvable container such as for example, as shown in
The basic hair treatment and a catalyst can also be together in an inert dry or suspended form, and then the reaction between the catalyst and the basic hair treatment material creates effervescence and due to the reaction between the basic hair treatment material and the catalyst. The hair treatment would come bubbling out the reservoir or from within the roller and the treatment would make its way out of the holes 30 of the roller and into the segments 19 of the roller 12 into the hair to be dyed or otherwise treated. The hair treatment would be contained within the segments 19 by a shroud 64, for example of the kind shown in
Containers, for example, as shown in
The receiver has external bayonet lugs 178, and a knurled handling ring 180. The external bayonet lugs 178 co-operate with corresponding bayonet lugs 184 inside the rim of the open end 166 of roller 12.
The applicator 186, which may be a container to which pressure is applied or a pressurised aerosol canister, containing hair treatment, is inserted into the end 170 of the applicator 162. The applicator 186 has raised external cylindrical portion 188 to fit inside a spring 194, a nozzle 190 at one end and a plunger at the other end. The external diameter of the nozzle 190 is chosen so that it fits inside the aperture 167, when the applicator 186 is pushed home into the receiver 166. The shoulder of nozzle 196 of the applicator 186 abuts the end 168 of the receiver, with the nozzle 190 protruding through aperture 167. The teeth 172 surround the plunger 192 and prevent it from sliding out of the receiver. The one end of spring 194 rests against the underside of plunger 192 and the other against the end of the receiver 168. Pressing the plunger 192 releases the hair treatment through nozzle 167 into the interior 182 of roller 12. Under pressure generated from the applicator 186, the hair treatment passes from the interior 182 through holes 30 in the roller into segments 19, as before, where it encounters hair contained in the segments 19 by the shroud 64. When sufficient hair treatment has reached the hair, or the applicator 186 has discharged, the plunger 192 is released; the spring 194 returns the plunger to its un-depressed position and the applicator 186 is closed.
As an alternative to the use of a pressurised canister, applicator 186 shown in the examples shown in
As a further alternative the applicator 186 may contain the hair treatment and catalyst or solvent separately, alternately they can be sealed within a segregated container such as shown in
In this latter arrangement, for example, hydrogen peroxide and hair-colour are sealed in a pressurised canister 186 but kept separate from one another by divider 201. The sealing excludes oxygen to prevent oxidisation. When the hydrogen peroxide and hair dye are expelled from the canister 186 through nozzles 199 and 200 they would become intermixed and react within the roller 12 as described previously in relation to
Alternately a flexible canister utilising a similar arrangement could be used and the canister can be deformed by the user to create the pressure to expel the contents.
If a surfactant and a dye were mixed together in a pressurised canister but to prevent oxidisation of the dye by a catalyst such as hydrogen peroxide, they are kept separate by means of a barrier 201 while the surfactant would create a foaming action, the mixture of the catalyst and dye would activate the dye as it was being expelled from the can in unison. A stabiliser to stabilise the hair-colour and hydrogen peroxide would need to be added, examples are STAC (Stearyltrimethylammonium chloride) and Cetanol (Cetostearyl alcohol), which are resistant to oxidation of hydrogen peroxide. To enhance foaming performance, a surfactant such as AGS (Sodium Acylglutamate) is used as the foaming agent as it is resistant to antifoaming properties of salt and solvent.
