Definitions

  • the present invention relates generally to cosmetic applicators. More particularly, disclosed herein is a cosmetic applicator with multiple distinct zones providing multiple, disparate performance characteristics in a single applicator and with a backwipe return arrangement.
  • Cosmetic dispensers for mascara and other liquid or pasty cosmetics commonly are founded on two pieces, a container and a cap.
  • the container typically comprises a bottle with an open inner volume for retaining a volume of the cosmetic material.
  • the cap normally has a rod or wand that projects distally therefrom.
  • a brush or other structure capable of retrieving cosmetic from the open inner volume of the bottle and applying the cosmetic to a body surface is retained at the distal end of the wand for being dipped into the volume of cosmetic.
  • the brush becomes loaded with the liquid or pasty material for permitting controlled application of the cosmetic, such as to the user's eyebrows or eyelashes.
  • the cosmetic dispenser can be sealed during periods of nonuse by a threaded engagement between the cap and a neck of the bottle.
  • mascara brushes have remained fundamentally similar to the twisted wire arrangement disclosed at least as early as 1964 in, for example, U.S. Patent No. 3,214,782 .
  • the brush or other structure can be employed in the successful application of the cosmetic.
  • Mascara is commonly applied in such a manner as are other liquid, semi-liquid, pasty and other cosmetics, including, by way of example and not limitation, lip gloss, concealer, and eye shadow.
  • the cosmetic brush Even after the application of cosmetic, however, the cosmetic brush retains a volume of cosmetic material thereon. Consequently, as the cosmetic brush is repeatedly removed and reinserted through the wiper, a reverse wiping action or backwipe occurs thereby producing a buildup of residue on the outer side of the wiper.
  • the backwiped cosmetic material is inherently messy and unsightly and wastes mascara product while reducing the ease and effectiveness of proper cosmetic application. This is particularly true as the backwiped product hardens over time thereby hindering use and closure of the cosmetic applicator and causing an undesirable condition referred to as clumping.
  • an object of embodiments of the present invention is to provide a cosmetic applicator with plural distinct zones for enabling multiple different performance characteristics to be achieved with a single applicator as defined in appended claims.
  • a more particular object of the invention is to provide a cosmetic applicator with a brush having first zone for achieving a first performance characteristic, a second zone for achieving a second performance characteristic, and a third zone for achieving a third performance characteristic.
  • Another object of embodiments of the invention is to provide a cosmetic applicator with plural zones that are distinct in performance and distinct in appearance thereby to permit the achievement of multiple application goals with a single applicator and the visual distinction between the zones permitting the same.
  • Still further embodiments of the invention seek to minimize or eliminate the buildup of backwiped cosmetic product through an effective yet elegantly simple wiper and applicator combination.
  • one embodiment of the invention comprises a cosmetic applicator with disparate material application zones for permitting the achievement of multiple cosmetic material application effects with the applicator.
  • the cosmetic applicator has a wire core formed from first and second wire segments twisted into a helical configuration to form a plurality of coils.
  • a plurality of radially disposed bristles are secured between the first and second wire segments of the wire core to form a brush head for being dipped into a volume of cosmetic material.
  • the bristles of the brush head are disposed in at least first, second and third distinct bristle zones, the first bristle zone being disposed over a proximal portion of the brush head, the second bristle zone being disposed over a mid-portion of the brush head, and the third bristle zone being disposed over a distal portion of the brush head.
  • the bristles of the first bristle zone are of a first bristle type disposed over a first series of coils of the wire core
  • the bristles of the second bristle zone are of a second bristle type different than the first bristle type and disposed over a second series of coils of the wire core
  • the bristles of the third bristle zone are of a third bristle type different than the first and second bristle types, said bristles of the third bristle zone being disposed over a third series of coils of the wire core.
  • the first bristle zone can provide a first material application property
  • the second bristle zone can provide a second material application property different from the first material application property
  • the third bristle zone can produce a third material application effect.
  • the first bristle zone can be round and of a generally consistent diameter from a proximal end of the brush head to a proximal end of the second bristle zone, and the second bristle zone can terminate in a frusto-conical distal portion.
  • the bristles of the separate bristle zones can differ in bristle counts and bristle colors.
  • first bristle zone comprising approximately 28 percent of the brush head
  • second bristle zone comprising approximately 44 percent of the brush head
  • third bristle zone comprising approximately 28 percent of the brush head.
  • Certain embodiments can have a first bristle zone that terminates in a frusto-conical proximal portion and a third bristle zone that terminates in a frusto-conical distal portion whereby the brush head presents a double taper configuration.
  • an oversleeve can be provided with a proximal, tubular base portion, a distal tip portion, at least one base strip with a proximal end coupled to the base portion and a distal end coupled to the distal tip portion, at least one open channel between the at least one base strip, and a plurality of tines that project from the base strip.
  • the oversleeve can be received over the brush head with the wire core disposed through the base portion of the oversleeve, the distal end of the wire core received into the tip portion, and the bristles of the first and second bristle zones passed through the at least one channel.
  • the distal end of the wire core can comprise a tip that extends distally beyond the bristle zones of the brush head, and the distal tip portion of the oversleeve can comprise a conical cap with a conical exterior and an inner receiving indentation that receives the tip of the wire core.
  • the tip of the wire core can take the form of a longitudinally aligned straight portion of the wire segments where the wire segments are disposed in a generally parallel relationship, and the first helical coil of the wire core can be disposed proximal to the straight portion.
  • Embodiments of the oversleeve can have first and second base strips separated by channels, and a row of tines can project from each base strip.
  • the number of tines in each row could approximately equal a number of coils over which the bristle zones of the brush head are disposed.
  • the rows of tine can have double-taper profiles.
  • the brush head can be fixed to a distal end of an applicator rod for enabling a dipping of the brush head into a volume of cosmetic material in an open inner volume of a cosmetic bottle.
  • the cosmetic bottle has an opening at a proximal end thereof for permitting an insertion and removal of the brush head and the rod and a wiper retained relative to the opening of the bottle for wiping excess cosmetic material from the brush head and the rod wherein the wiper has a flexible inner ring with an inner annular opening for permitting passage of the brush head and the rod.
  • a cosmetic material passageway can be incorporated into the flexible inner ring of the wiper, and that passageway can be supplemental to the inner annular opening of the flexible inner ring. With this, backwiped cosmetic material can be pressed through the cosmetic material passageway for return into the open inner volume of the bottle.
  • the cosmetic material passageway can comprise a semicircular lobe contiguous with the inner annular opening in the flexible inner ring.
  • the wiper can further include a cylindrical outer wall, and an annular shoulder can be disposed at the proximal end of the applicator rod.
  • the flexible inner ring of the wiper can have a proximal surface sloped at an angle away from the opening of the cosmetic bottle, and the shoulder can have a distal surface sloped at substantially the same angle away from the proximal end of the applicator rod.
  • FIG. 1 A manifestation of the present invention for a cosmetic applicator with disparate material application zones is indicated generally at 10 in FIG. 1 .
  • the cosmetic applicator 10 has an application rod 12 with a proximal end and a distal end.
  • a cap 14 which also acts as a handle during the application of liquid or pasty cosmetic material (not shown), is affixed to the proximal end of the rod 12 as is best seen in FIG. 6 .
  • a cosmetic brush head 16 is affixed to the distal end of the rod 12 for being dipped into a volume of liquid or pasty cosmetic material retained in the open inner volume 56 of a cosmetic bottle, such as that indicated generally at 52 in FIG. 8 .
  • the cosmetic brush head 16 can be seen to be founded on a twisted wire core 34.
  • the twisted wire core 34 is formed by first and second wire segments twisted into a helical configuration to define a central longitudinal axis. While the first and second wire segments could be separate strands of wire, the twisted wire core 34 is preferably formed from a single wire folded over to establish the first and second wire segments and then twisted into the desired helical configuration to form a plurality of coils therealong.
  • the cosmetic brush head 16 has a proximal base portion 36 and a distal tip 38.
  • the cosmetic brush head 16 has multiple distinct bristle zones.
  • the multiple zones of bristles permit the achievement of multiple performance characteristics by the use of a single cosmetic applicator 10. More particularly, in the present embodiment, first, second, and third distinct zones 18, 20, and 22 of brush filaments are retained between the twisted wire core 34 thereby to establish a brush head 16 having three distinct bristle zones.
  • the wire core 34 has a tip 38 that projects distally beyond the third zone 22.
  • the tip 38 comprises a longitudinally aligned straight portion of the folded-over end of the twisted wire core 34 that is devoid of bristles therebetween and where the first and second strands of the wire core 34 are disposed in a generally parallel relationship.
  • the first coil of the twisted wire core 34 is disposed proximal to the straight portion.
  • the proximal base portion 36 of the wire core 34 projects proximally beyond the first zone 18 by a given number of coils.
  • the brush filaments of the first, second, and third zones 18, 20, and 22 cooperate to form the brush head 16.
  • the first, second, and third zones 18, 20, and 22 occupy approximately eighteen coils of the twisted wire core 34 in total.
  • the first zone 18, which may alternatively be referred to as the proximal zone is made up of brush filaments occupying approximately five coils or approximately 28 percent of the brush head.
  • the third or distal zone 22 is made up of brush filaments occupying approximately five coils or approximately 28 percent of the brush head 16.
  • the second or central zone 20, which resides between the first and third zones 18 and 22, is made up of brush filaments occupying approximately eight coils or 44 percent of the brush head 16.
  • the cosmetic brush 16 can be fixed to the rod 12 in any effective manner. Looking specifically to FIG. 6 , for example, the cosmetic brush 16 can be retained relative to the rod 12 by an insertion of the base portion 36 of the wire core 34 into a corresponding longitudinal, centered borehole in the distal end of the rod 12. If necessary, the brush head 16 can be secured in place by a crimping or other deformation of the base portion 36 of the wire core 34.
  • the base portion 36 of the wire core 34 is flattened to some extent, heated, and then inserted into a round borehole in the distal end of the rod 12 whereby the plastic rod melts and then hardens around the base portion 36 of the wire core 34 to hold the wire core 34 and thus the brush head 16 in general in place relative to the rod 12.
  • the bristles of the brush head 16 in FIG. 5A are formed, such as by trimming or otherwise, to have what can be referred to as a reverse double taper configuration.
  • the reverse double taper configuration is designed to yield superior product loading, unloading, and ease of use. Tapering at both ends of the brush head 16 together with a central portion of a generally consistent diameter over a given length permits the use of both tapered ends to reach particular areas, such as the corners of a user's eyes, while permitting the flat central portion to be used to apply a larger volume of material.
  • the tapering of the brush head 16 can begin where the first zone 18 meets the second zone 20 and where the second zone 20 meets the third zone 22.
  • the second zone 20 is of a consistent diameter
  • the first and third zones 18 and 22 are of progressively reducing diameters toward the proximal and distal ends of the brush head 16 respectively, each thereby establishing a frusto-conical shape.
  • the brush head 16 of FIG. 5B which again has a double taper.
  • First, second, and third bristle zones 18, 20, and 22 are provided with each bristle zone having different material application characteristics.
  • the brush head 16 smoothly transitions from zone to zone with a progressive reduction in diameter from a maximum at the midpoint of the brush head 16 and at a midpoint of the second bristle zone 20 to minimum at the ends of the first and third bristle zones 18 and 22. With this, the brush head 16 presents a smooth profile with a symmetrical, arcuate outer shape.
  • the three zones 18, 20, and 22 are different from one another in material application properties.
  • the zones 18, 20, and 22 can differ in material retention characteristics, defining and separating characteristics, and volumizing and building characteristics.
  • the differences in the zones 18, 20, and 22 can be achieved by varying one or more of a plurality of factors, including bristle density, bristle material, bristle length, bristle diameter or thickness, bristle cross-sectional shape, bristle positioning, and bristle end treatment.
  • the bristles of the first zone 18 can be solid rods made from a synthetic polymer, such as nylon, with a bristle diameter of 0.003 inches.
  • the bristles of the first zone 18 can be disposed in well defined rows, and the bristles of the first zone 18 can have a unique filament count relative to the second and third zones 20 and 22. With this, the first zone 18 will tend to produce a first material application effect, namely a definition and separation in the treated hair in this embodiment.
  • the bristles of the second zone 20 can be hollow tubes with an outer bristle diameter of 0.005 inches.
  • the bristles can be disposed in interwoven filament rows and with a unique filament count relative to the first and third zones 18 and 22. Under that arrangement, the bristles of the second zone 20 will tend to achieve a second material application effect, namely a volumizing and building effect in the treated hair in the embodiment shown and described.
  • the third zone 22 can produce a third material application effect by being formed with solid, round bristles that are disposed in defined filament rows like those of the first zone 18.
  • the bristles of the third zone 22 have a different diameter relative to those of the first zone 18.
  • the bristles of the third zone 22 can have a diameter of 0.004 inches, and a unique filament count relative to the bristles of the first and third zones 18 and 22.
  • the bristles of the third zone 22 will also tend to produce a defining and separating effect, but it could be different in material application property from the defining and separating effect achieved by the bristles of the first zone 18.
  • the function of the cosmetic applicator 10 and the utility of the different material application effects produced by the multiple material application zones 18, 20, and 22 can be further improved by promoting the ability of the user to differentiate visually between the multiple zones 18, 20, and 22.
  • Such a visual differentiation will not only accentuate the multiple performance characteristics achieved by the cosmetic applicator 10, but it will also permit the user to identify the desired zone 18, 20, or 22 to be employed based on the user's desired material application effect.
  • this is achieved by having bristles of each of the first, second, and third zones 18, 20, and 22 of different colors.
  • the bristles of the first zone 18 with their first defining and separating effect can be blue in color
  • the bristles of the second zone 20 with their volumizing and building effect can be natural or tan in color
  • the bristles of the third zone 22 with their second defining and separating effect can be red in color.
  • the rod 12 of the cosmetic applicator 10 can have a valve seal at the proximal end thereof.
  • the valve seal can be disposed within the cap 14 to push any backwiped product into the bottle 52, such as that shown in FIG. 8 .
  • the rod 12 can be tapered to prevent cosmetic product from producing undesirable hydraulic pressure during the insertion and removal of the rod 12 of the cosmetic applicator 10 relative to the bottle 52.
  • Threads 42 on the inner wall of the cap 14 can engage threads 54 on the neck of the bottle 52 to retain the cosmetic applicator 10 relative to the bottle 52 and to seal the open inner volume 56 of the bottle 52.
  • the bottle 52 can retain a wiper 58 adjacent to the neck thereof for wiping excess product from the brush head.
  • the wiper 58 can in certain embodiments be a one-piece arrangement formed from a soft polymer, such as thermoplastic elastomer (TPE) or rubber. Locking ribs on the wiper 58 can secure the wiper 58 in relation to the bottle 52.
  • the performance of the unique multi-zone configuration of the brush head may be improved by cosmetic material, such as mascara, that is specifically calibrated to exploit the disparate material application characteristics of the zones 18, 20, and 22. Performance will be maximized by employing cosmetic material with preferred ingredients, preferred proportions, and a preferred range of viscosity.
  • cosmetic material such as mascara
  • the unique performance of the cosmetic applicator 10 can be furthered by additionally incorporating what can be referred to as an oversleeve 24.
  • the oversleeve 24 is shown received over the cosmetic brush 16 in FIGS. 1 and 2 and then apart in FIGS. 3 and 7 .
  • the oversleeve 24 has a proximal, tubular base portion 46 and a distal tip portion 32.
  • the distal tip portion 32 comprises a conical cap with a conical exterior and an inner receiving indentation.
  • First and second base strips 28 and 30 communicate longitudinally from proximal ends fixed to the base portion 46 to distal ends fixed to the tip portion 32.
  • the base strips 28 and 30 are spaced 180 degrees apart and are separated by open channels, which are disposed in opposition communicating longitudinally along the oversleeve 24 from the base portion 46 to the tip portion 32.
  • a first longitudinally aligned row of tines 26 projects from the first base strip 28, and a second longitudinally aligned row of tines 26 projects from the second base strip 30.
  • the base strips 28 and 30 are disposed 180 degrees apart. Consequently, the rows of tines 26 project in diametric opposition 180 degrees apart.
  • the oversleeve 24 can be slid over the wire core 34 with the wire core 34 received through the tubular base portion 46 and then between the base strips 28 and 30 until the tip 38 of the wire core 34 is received into the inner receiving indentation of the tip portion 32 of the oversleeve 24.
  • the bristles of the first, second, and third zones 18, 20, and 22 of the brush head can be received through the channels in the oversleeve 24 so that the bristles project therethrough.
  • the oversleeve 24 When the oversleeve 24 is fully engaged with the wire core 34, a proximal end of the base portion 46 of the oversleeve 24 is received into a corresponding annular ring formed at the distal end 48 of the rod 12 to prevent dislodging of the oversleeve 24 and undesirable material accumulation at the proximal end thereof.
  • the oversleeve can be additionally secured by one or more stakes 40 passed through the distal end of the rod 12 and through an aperture 50 in the base portion 46 of the oversleeve 24. Of course, other means for securing the oversleeve 24 in place can be employed as necessary.
  • the number of tines 26 can in certain embodiments correspond to the number of coils over which the bristles of the brush head 16 are disposed. With that, in the embodiment depicted in FIGS. 1 , 2 , and 3 , there can be eighteen tines spaced over the length of each base strip 28 and 30 corresponding to the eighteen coils over which bristles are retained by the wire core 34.
  • the tines 26 in each row have a double taper profile with a central group of tines 26 of a generally consistent height and proximal and distal series of tines 26 that taper to progressively shorter heights.

  • the oversleeve 24 can be formed in any appropriate manner. Under certain practices of the invention, the oversleeve 24, including the base and tip portions 46 and 32, the base strips 28 and 30, and the tines 26, can be molded or otherwise formed as a unit.
  • the material for the oversleeve 24 could vary within the scope of the invention depending on, among other things, desired material application characteristics and the cosmetic to be applied.
  • One presently preferred embodiment forms the oversleeve 24 from a polymeric material, such as a thermoplastic polyester elastomer.
  • the tines 26 could be of any suitable cross section.
  • the tines 26 can have a diamond-shaped cross section with the goal of enhancing the combing and lengthening characteristics achieved by use of the tines 26.
  • the diamond shape is believed to grab the hair to which cosmetic is to be applied as the tines 26 pass among and between that hair.
  • the oversleeve 24 With two oppositely projecting rows of tines 26, the oversleeve 24 will be capable of passing through the wiper 58 while permitting the wiper 58 to perform its primary function of wiping the bristles of the brush head most effectively.
  • the oversleeve 24 and the tines 26 can be black in color to differentiate from the remainder of the cosmetic applicator 10 and again to facilitate the most efficient use of their performance characteristics.
  • first and second base strips 28 and 30 with opposed tines 26 projecting therefrom have been found preferred in certain applications, it will be noted that just one base strip 28 or more than two base strips 28 and 30 is possible.
  • an oversleeve 24 is possible having first, second, and third base strips that could be spaced evenly at 120-degree separations. Tines 26 could again project from each base strip. With this, when the oversleeve 24 is passed over the brush head 16, tines 26 will project at 120-degree intervals and sections of the brush head 16 project through channels between the base strips in three areas.
  • An applicator not according to the invention can have fewer zones of bristles, as shown, for example, in FIGS. 9 and 10 .

  • a peripheral ridge 72 is disposed at the proximal end of the outer wall 70 of the wiper 58 for overlying the proximal or outer end of the neck of the bottle 52, and a plurality of tabs 74 project from adjacent to the distal end of the outer wall 70 of the wiper 58 for overlying the distal end of the neck or inner end of the bottle 52 thereby securing the wiper 58 in place.
  • the wiper 58 has a flexible inner ring 76 that projects radially inwardly from the outer wall 70. As best seen in FIG. 14 , the flexible inner ring 76 has an inner annular opening 80 for permitting passage of the rod 12 and the brush head 16.
  • the inner annular opening 80 can be smaller in diameter than the diameter of the rod 12 and of the brush head 16 so that excess cosmetic material is wiped from the rod 12 and the brush head 16 as they are drawn from the open inner volume of the bottle 52.
  • the proximal or outer surface of the flexible inner ring 76 is sloped at a given angle away from the proximal end of the wiper 58 and away from the proximal end of the bottle 52 when the two are engaged as in FIG. 8 .
  • the angle at which the distally-facing surface of the sloped shoulder 45 is disposed can substantially match the angle at which the proximally-facing surface of the inner ring 76 is disposed.
  • the facing surfaces of the sloped shoulder 45 and the inner ring 76 are disposed at matching twenty-five degree angles.
  • the base portion 64 can have an outer diameter marginally less than the inner diameter of the outer wall 70 of the wiper 58. In one contemplated embodiment, for instance, the base portion 64 has an outer diameter of approximately 0.391 inches while the outer wall 70 of the wiper 58 has an inner diameter of approximately 0.422 inches.
  • the base portion 64 will act as a piston within the cylinder defined by the outer wall 70 of the wiper 58 during reinsertion into the bottle 52. Any backwiped cosmetic product will tend to be pressed distally toward the sloped proximal surface of the wiper 58 and thus toward the open inner volume of the bottle 52. As noted above, the inner opening 80 of the inner ring 76 of the wiper 58 is marginally smaller in diameter than the diameter of the rod 12. With this, cosmetic product pressed by the base portion 64 would tend to accumulate between the facing surfaces of the shoulder 45 and the inner ring 76 of the wiper 58.
  • a cosmetic material passageway 78 is disposed in the inner ring 76 of the wiper 58 supplemental to the annular inner opening 80.
  • the passageway 78 is contiguous with the inner opening 80 in the form of a semicircular lobe. This can be considered advantageous in that, among other things, the passageway 78 is disposed at the inner, distal edge of the inner ring 76. In other embodiments, the passageway 78 could otherwise be disposed in supplementation of the inner annular opening 80, such as by being disposed in the body portion of the inner ring 76 separate from the annular inner opening 80.
