Definitions

  • Products for the removal of unwanted hair from the body have been commercially available for many years. These products have focused primarily on facial, underarm and leg hair removal. There is however a growing desire from consumers for removal of hair for other areas of the body including intimate areas such as the pubic areas including the bikini area. Whilst a number of products are commercially available for hair removal at the bikini area, they are not particularly satisfactory and consumers still tend to use hair removal products designed for the removal of hair from traditional areas such as axilla and legs.
  • a pubic or bikini product The primary benefit of a pubic or bikini product is to cut hairs to or below skin level with minimal insult and subsequent side-effects to the surrounding skin.
  • women indicate that they continue to experience significant side-effects when shaving in this area such as irritation, in the form of redness (erythema), bumps, ingrown hairs, itchiness and soreness. These side effect may also manifest themselves immediately after shaving and or hours or even days after the shaving event has occurred.
  • WO2012/061343 describes a razor cartridge wherein the angle between the primary blade and the blade plane is greater than the angle between the final blade and the blade plane of the blade array to improve the balance between closeness and comfort of a shave.
  • the invention relates to a shaving razor (10) comprising a cartridge (12) comprising a housing (16) having a front portion (18) and a rear portion (20), a guard (30) at the front portion (18)of said housing (16) and a cap (32) at the rear portion (20) of the housing (16) and a blade array (26) located in-between the guard (30) and cap (32), wherein the blade array (26) comprises at least two blades, a primary blade (40)and a final blade (44), each blade (26) having a blade edge (48, 50) that extends parallel to the housing (16); having a blade plane x tangential to the primary blade edge (48) and the final blade edge (50), wherein each angle between each blade (26) and the blade plane x is 30° or greater; and wherein said cartridge (12) has a skin contacting surface foot print of from 600mm 2 to 800mm 2 , preferably from 620mm 2 to 750mm 2 .
  • the invention also relates to the use of a razor cartridge as claimed, for the removal of hair from the pubic area, preferably the bikini area.
  • the cartridge typically comprises 1, 2, 3, 4 or 5 elongated blades edges usually positioned between a first and second end, said one or more elongated blade edges comprising a tip extending towards said first end.
  • the razor cartridge may include a guard as well as a skin engaging member and one or more lubricating members.
  • a variety of razor cartridges can be used in accordance with the present invention.
  • a plurality e.g. 2, a first and second
  • lubricating members may be provided on the cartridge, with the first skin engaging member comprising the same composition or different.
  • These lubricating members may be placed collectively (for example adjacent to one another) ahead of or behind the elongated edges (e.g. blades on a razor cartridge), including side by side, or separately with one ahead of the elongated edges and the other behind.
  • the lubricating member may be free standing utilizing a suitable attachment means such as adhesive or may be contained at least partially within a container.
  • the cartridge comprises a guard comprising at least one elongated flexible protrusion to engage a user's skin.
  • the at least one flexible protrusion may comprise flexible fins generally parallel to said one or more elongated edges.
  • Said at least one flexible protrusion may additionally or alternatively comprise flexible fins comprising at least one portion which is not generally parallel to said one or more elongated edges.
  • suitable guards include those used in current razor blades and include those disclosed in U.S. Patent Nos.
  • FIG. 1a and 1b show a wet shaving razor 10 formed of a razor cartridge 12 attached to a handle 14.
  • the razor cartridge is formed of a housing 16 having a front 18, a rear 20 and first and second opposing side walls 22, 24 disposed transverse to and between the front wall and rear wall. Two or more blades 26 with sharp cutting edges 28 are mounted within the housing 16 and extend between the first and second opposing side walls 22, 24.
  • the razor cartridge 12 has a first skin contact point, typically a guard 30, located ahead of the blades and a second skin contact point, typically a cap 32, located behind the blades.
  • the guard is disposed at the front of the housing and the cap is disposed at the rear of the housing.
  • the respective positioning of the guard and cap may be reversed or the guard may be formed separately to the housing and mounted directly to the razor handle.
  • Lubricating members (54) are located forward and aft of the blades.
  • a span ⁇ s is defined between each pair of adjacent blade edges, and a total span ⁇ ts is defined between the primary blade edge 48 and the final blade edge 50.
  • the span between adjacent blade edges may be the same for each pair of blades in a cartridge, or the span between adjacent blade edges may vary at different points in the cartridge. For example, in a three-blade cartridge having a primary, second and final blade, the span between the primary and second blade edges may be less than, equal to or greater than the span between the second and final blade edges.
  • Each of the blades 40, 44 extends away from the blade plane x at an angle ⁇ p relative to the blade plane x.
  • the present inventors have found that by providing the blades at an angle of at least 30°, it is possible to further improve the balance between reduced irritation and closeness for the removal of pubic hair.
  • a typical blade edge is shown in FIG. 5 , having a sharp tip 60 and facets 62 that extend away from the sharp tip into a body 64 of the blade.
  • a user While shaving pubic (bikini) hair, a user is likely to experience varying degrees of comfort/discomfort depending on how much of the blade edge is presented to the skin.
  • the angle ⁇ is increased, the surface area of the blade presented to the skin decreases and thus the pressure on the skin increases, leading to an increase in discomfort experienced by a user.
  • As the angle ⁇ is decreased more of the facet 62 is presented to the surface of the skin, increasing the surface area of the blade presented to the skin and a user experiences less discomfort.
  • a skive-cut occurs when the resultant angle of the cut hair tip is greater than 45° to the normal of the hair fibre (66), as shown in FIG. 7 leaving one side of the hair longer than the other side.
  • a user may need to shave more frequently, or increase the number of shaving strokes.
  • the blade angle ⁇ is increased, there is less chance that contact between a blade edge and hair will result in a skive-cut.
  • the present inventors have found that increasing the blade angle to an angle of at least 30°, preferably between about 30° and 60° for all blades in a cartridge, ensures both the desired comfort in use, and a reduction in proportion of skive cut hairs. This results in a decrease in irritation occurring post shaving for pubic hair removal.
  • the primary blade and all additional blades are independently positioned at an angle ⁇ p of from about 30° or about 35° or about 36° or about 45° or about 50° or about 55°.
  • the blades are all at a blade angle, preferably of between about 35° and about 50°, more preferably from about 35° and about 45°, even more preferably between about 36° and about 43° and most preferably between about 37° to about 42.5°. In one embodiment all blades have the same blade angle.
  • angled hair tip shape can be compared in dimension to the tip of a microneedle, a device specifically designed to puncture the skin.
  • the relationship between insertion force and tip shape is such that an angled tip shape can be inserted into the skin with much lower force than a blunt tip shape.
  • the Applicant believes that hairs with a blunt tip shape require significantly more insertion force to re-enter the skin post shaving, and therefore are less able to do so and hence less likely to trigger the associated cycle of irritation.
  • the Applicant has found that bikini hair can be cut to form a blunt hair tip by the use of blade edges inclined at a higher angle to the skin, versus the standard angle in common commercially available razor cartridges.
  • FIG 6 shows a skin contact plane y which is tangential to skin engaging surfaces of the guard 30 and cap 32.
  • Exposure of a blade is defined as the distance, p, of the blade edge 28 from the exposure plane. Where a blade edge lies beneath the exposure plane, this is classified as a “negative exposure”. If the blade lies above the exposure plane, this is classified as a “positive exposure”. If the blade edge lies in the exposure plane, the blade edge has zero exposure.
  • the primary blade 40 has negative exposure
  • the final blade 44 has positive exposure
  • the exposure of any additional blades between the primary and final blades have progressively increasing exposure from the front to rear of the cartridge.
  • This form of progressive geometry is described in detail in EP 0 722 379 .
  • Variation in blade exposure across a cartridge results in a varied load distribution across the blades of a cartridge. The load on respective blades reduces as the exposure is reduced. Accordingly, in such an embodiment, least load is applied to the primary blade during shaving while most load is applied to the final blade. This is a result of the pressure applied to skin by the blades during shaving - where the blade protrudes more relative to the exposure plane, effectively the skin contact plane, while shaving, the blade protrudes further into skin.
  • the blades of the present invention may be secured to the housing in any known way, for example, the blades may be attached to blade supports, or they may be bent blades that are secured directly to the housing.
  • the housing has a blade retaining member having a plurality of slots for receiving either the blade supports or, where bent blades are used, the blades.
  • the angle of the respective blades relative to the blade plane x can be determined by an angle in the blade support, where blade supports are used, or by a bend in a blade where bent blades are used.
  • the angle of bend in the respective blade supports or bent blades may be kept the same, and the angle of the respective slots in the blade retaining member may be varied to result in blade edges at varying angles to the blade plane x.
  • the blades are usually carried by the housing, which is generally a molded plastic frame, either independently of each other or in unison under forces imparted on the blades by the skin during shaving.
  • the blades are mounted fixedly within slots in a blade retaining member.
  • the blades may be floatably mounted within the housing.
  • the plurality of blades is supported by one or more spring loaded blade retaining member where the blades are permitted to respond to the forces encountered during shaving.
  • the Applicant has further found that the overall hair removal performance of the blades as discussed hereinabove, is not effective if contact between the skin and blade is not achieved and maintained during the shaving process.
  • the pubic area unlike the face and legs for example is not however fully and readily visible to the consumer conducting the hair removal process. Consequently, the consumer is more reliant on tactile responses in order to try and achieve the desired hair removal result without causing injury.
  • the Applicant has surprisingly found that the overall size and dimensions of the cartridge hereinafter referred to as the cartridge footprint can improve cartridge fit and also improve contact in the bikini area particularly with regard to skin mobility. This aids greater precision and efficiency of hair removal in this area and importantly ensures the appropriate blade contact with the skin. Whilst not bound by theory, the Applicant also believes that the footprint allows consumers to achieve the desired hair removal in fewer strokes and or overstrokes, thus reducing the extent of skin insult and the associated irritation.
  • the footprint or skin contacting surface is define by the peripheral edge of the housing (34).
  • the cartridge may have a skin contact surface area or footprint of from about 600mm 2 to 800mm 2 , preferably from about 620mm 2 to 750mm 2 , more preferably from between about 635mm and 650mm 2 or from about 725mm 2 to 745mm 2 .
  • the cartridge may have a maximum length (c 1 ) of from about 30mm to 60mm, preferably from about 35mm to about 50mm, more preferably from about 40mm to 45mm.
  • the cartridge may have a maximum width (c w ) of from about 15mm to 25mm, preferably from about 20mm to 25mm.
  • the cartridge may be provided in a generally regular rectangular or oval shape. However, in one embodiment the cartridge may be provided such that the front portion of the cartridge is shorter than the rear portion of the cartridge as shown in FIG. 8 .
  • the front and rear portions of the cartridge are defined by the cartridge housing. In such embodiments the front and rear portions are preferably joined by curved side walls.
  • the shorter front portion is typically centered. In one embodiment the aspect ratio of the front and rear portions is from 2 to 1. Whilst not being bound by theory it is believed that having a shorter front portion aids in the smooth flow of the cartridge across the mobile skin present in the pubic area.
  • the Applicant has found that the size and dimensions of the cartridge may judiciously mitigate the discomfort arising from the increase blade tip pressure when blades are present at an elevated angle.
  • the smaller footprint size increases the ratio of housing materials to lubricant in contact with skin during a shaving stroke, resulting in a reduction in perceived dragging which can cause discomfort.
  • the preferred footprint also readily conforms and fits the curves of the bikini body site and thereby enables hairs to be captured efficiently and comfortably with the increased blade angles.
  • the handle can also improve the overall shaving performance in the bikini area in combination with high blade angle geometry.
  • the Applicant has found that the relative length and width of the handle enables the user to be confident in locating the cartridge appropriately and maintaining control without further restricting the visibility of the area to be shaved by the user's hand.
  • the handle length has been found to be an important vector with regard to consumer ease, comfort and control of use in the bikini area.
  • Traditional razor handles have been found to be too long, whereas smaller travel products for example have been found to have a handle which is too short and or too wide for effective use in the pubic area.
  • the handle suitable for use with the invention may have a length (h l ) of from about 55mm to 90mm; preferably from about 60mm to 80mm, more preferably from about 70mm to 80mm.
  • the handle may have a maximum width (h w ) of from about 45mm to25mm, preferably from about 40mm to 30mm, more preferably from about 33mm to about 37mm.
  • the handle has an aspect ratio of 2.
  • the handle may have a maximum depth (h d ) of from about 20mm to 30mm, preferably 22mm to 36mm, more preferably about 24mm.
  • the handle has a body (70) which may be provided as a solid body or it may be provided as a body having a hollow body having a central void or gap (76
  • the overall shape of the handle may be for example generally oval or a partial tear drop shape or a U shape.
  • the void or gap (76) may be enclosed or open from at least one side (88, 90) of the handle as shown in FIGS.1a , 1b and 4 for example.
  • the provision of a hollow readily enables the deformation of the handle material upon application of force by the user.
  • the handle typically has a front surface (72) and a rear surface (74).
  • the handle has a hollow or gap (76) between at least a portion of the front (72) and rear (74) surfaces of the handle to thereby form a hollow (76) in the body.
  • the front (72) and rear (74) surfaces are preferably connected to one another at least at the distal (84) and proximal ends (86) of the handle.
  • the front (72) and rear (74) surfaces are not typically substantially connected along their respective side edges (88, 90) but only at the distal (84) and proximal ends (86).
  • the handle is in the form of a loop or U shape as shown in FIGS 1A , 1B and 4 whereby the front (72) and rear surfaces (74) form a central void or gap (76) in-between at least a portion of the surfaces and is contained thereby.
  • the gap (76) may have a maximum length of from about 30mm to 65mm, preferably from about 40mm to 60mm, more preferably from about 50mm to 60mm.
  • the aspect ratio of the handle length and the gap length is form about 1 to 2, preferably from about 1.2 to 1.3.
  • the gap may have a maximum width of about 5mm to 30mm, preferably from about 10mm to about 20mm.
  • the front (72) and rear surfaces (74) of the handle each have a respective inner surface (73, 75) adjacent the gap (76).
  • the width of the front surface (72) and inner surface (73) and rear surface (74) and inner surface (75) is from about 10mm to 20mm, preferably between about 12mm and 16mm.
  • the provision of a gap in-between the front and rear surfaces readily enables the handle to be flexed by the user during use to apply pressure to the skin surface as and when necessary. Moreover, the flexibility enables the handle to be peeled away from the skin when the cartridge is in contact with the skin to enable visibility by the user during use
  • At least a portion of the front and or rear surfaces (72, 74) are independently from one another flexible and deformable, preferably resiliently deformable so as to flex upon the application of pressure by the user.
  • At least a portion of the handle is at least partially, preferably substantially transparent.
  • the peripheral edge (80) of the handle may be transparent or the centre of the handle may be transparent or the entire handle may be transparent.
  • the transparent portions may also be coloured.
  • the handle may be provided in contrasting colours; for example the peripheral edge may be provided in one colour and the centre portion may be provided in a different colour.
  • the handle may be manufactured from any suitable material known in the art such as for example thermoplastics such as polypropylene, acrylonitrile butadiene styrene, high impact polystyrene, polycarbonate, polyphenylene ether/polystyrene blend, impact modified styrene acrylic copolymer, and/ or mixtures thereof using standard manufacturing techniques. Suitable methods include injection moulding and die casting and optionally 'additive or subtractive manufacturing' techniques and or co-molding techniques.

Suitable methods include injection moulding and die casting and optionally 'additive or subtractive manufacturing' techniques and or co-molding techniques.
  • the front and rear surfaces (72, 74) of this embodiment may be formed by co-molding the peripheral edge material (80) with a deformable material, such as a thermoplastic elastomer.
  • a deformable material such as a thermoplastic elastomer.
  • the deformable material may have a shore hardness in the range of 15 to 85 Shore A, preferably 20 to 45 Shore A, thereby allowing the front and rear surfaces of the handle to touch under a palmer pinch grip, and return to the original non deformed shape under normal usage.
  • Such materials are chosen for their strong adhesion to the peripheral edge framework. These materials also permit a translucent finish and facilitate ease of manufacture in moulding or vacuum casting.
  • the front and or rear surfaces (72, 74) may further be provided with a tactile surface (82) to provide improved grip to the user during use. This may assist in providing reassurance to the user of a secure grip when the product is used in a wet and slippery environment.
  • the tactile surface (82) is provided in the centre portion of the front and or rear surface of the handle. Suitable tactile surfaces include raised portions in the form of bumps, ridges, dips etc. The tactile surface may in addition also provide a visual cue or a logo or branding on the front and or rear surface.
  • the tactile surface (82) is provided on the front surface (72) to provide a finger rest (92) and or may be located on a raised portion of the front surface (72), preferably at the proximal end (84) to form a finger rest.
  • the finger rest (92) ensures the finger does not slip onto the back of the cartridge. Additional grip may be provided from an extruded logo located on the rear surface (74) of the handle.
  • Another tactile surface (82) providing a gripping portion may be provided at the distal end (86) of the handle.
  • Tactile surface (82) maybe be provided by the material of the handle itself or it may be provided as a separate layer.
  • the tactile surface maybe coloured differently from the front and rear surface to provide a visual cue to users.
  • the Applicant believes that the deformable nature of the handle may help to reduce and balance the blade load by acting as a suspension system, cushioning the load transferred to the cartridge from the handle and therefore the discomfort which can be associated with high blade angles.
  • the smaller handle size enables the user to have a large amount of control over the razor which is needed when using blades which may cause discomfort. This also improves the safety of high blade angle embodiments.
