Definitions

  • the present invention relates to a cosmetic applicator and, in particular, to an applicator for applying liquid cosmetics, such as mascara, to eyelashes or other parts of the body.
  • an applicator or brush The general purpose of an applicator or brush is to pick up an adequate supply of material, such as mascara, from a container, carry it from the reservoir of the container without dripping, and apply it evenly to the particular area of the body, such as, for example, eyelashes. This needs to be achieved without depositing lumps or blobs of the material on the eyelashes.
  • material such as mascara
  • the bristle ends of the applicator have a distribution that permits the pick up of an adequate supply of material and retains it until it is applied to the eyelashes. It is also important that the filaments that form the bristle ends have sufficient structural strength to comb the material or mascara through the eyelashes.
  • a conventional mascara brush has a twisted wire core, and a bristle portion.
  • the bristle portion has a plurality of plastic filaments. Each plastic filament is gripped by the twisted wire medially of its ends to form bristle ends.
  • US-A-4 887 622 is directed to a brush of this type in which the bristle ends extend radially from the core as a helical array and are disposed in a manner to avoid interference of the bristle ends of one turn with the bristle ends of adjacent turns.
  • Each filament has a diameter from 0.10 to 0.25 mm.
  • the number of filaments per helical turn of the twisted wire core is approximately 10 to 40.
  • US-A-4 993 440 is also directed to a mascara brush that has a twisted wire core, and a bristle portion.
  • the bristle portion has a plurality of plastic filaments. Each plastic filament is gripped by the twisted wire medially of its ends to form bristle ends.
  • This patent also provides that each filament has one or more U or V shaped capillary channels formed in its surface. The sides of the U or V shaped capillary channel converge slightly toward each other near their free ends before again diverging outward to a zone where the channel opens out at the surface of the filament.
  • the bristle ends are disposed to extend radially from the wire core, and are distributed to avoid interference of the bristle ends of one turn with the bristle ends of adjacent turns.
  • US-A- 4 733 425 is directed to a brush of the type described above in U.S. Patent No. 4,887,622 .
  • the plastic filament bristle ends flare outwardly in various directions when gripped by the twisted wire. This outward flaring forms a bristle end distribution pattern that is uniform at the bristle face.
  • the filament is described as a hollow or tubular polyamide, or one that has a non-circular cross section.
  • an applicator or brush according to the present invention generally represented by reference numeral 10.
  • the applicator 10 has a core 12, a rod 14, a cap 16 and a bristle portion 20.
  • the core 12 is formed from a U-shaped length of wire that is twisted about itself.
  • the wire for wire core 12 is preferably a metallic wire.
  • Rod 14 covers a portion of wire core 12 that extends to the right of bristle portion 20. Rod 14 is secured to this portion of wire core 12 by a suitable fastener, such as by coining and heat sealing. Rod 14 extends into cap 16 and is suitably secured to the cap by conventional means.
  • bristle portion 20 is formed of a plurality of filaments 30.
  • Bristle portion 20 has a first end 24 towards rod 14, and a second or free distal end 26 opposite the first end.
  • Second end 26 has a taper 28.
  • bristle portion 20 has a generally uniform and square cross section 21 with taper 28 having a generally circular cross section 29, as shown clearly in Fig. 2 .
  • the bristle ends 22 are clipped by conventional cutter means. In the cutting operation, the edges or corners are rounded to give a comfortable application.
  • Each filament 30 is preferably formed of a plastic filament.
  • Each plastic filament 30 is crimped medially of its ends by wire core 12 whereby its ends form bristle ends 22.
  • bristle ends 22' are formed by a filament 30' crimped by core 12 as shown in Fig. 3 .
  • the bristle material and shape is such that the crimping action causes the bristle ends 22' to flare radially outward from core 12 in various directions.
  • the effect of the multidirectional flaring of bristle ends 22 is that they uniformly fill the spaces between adjacent turns of core 12. This gives the effect of a uniform distribution of bristle ends 22 throughout bristle portion 20.
  • the density of filaments 30 in bristle portion 20 is preferably in the range of about 45 to about 60 filaments per helical turn.
  • a helical turn is one turn of core 12. More preferably, the density is in the range of about 48 to about 60 filaments per turn. Most preferably, the density is in the range of about 45 to about 55 filaments per helical turn. A density in this range has been found to give an even application of mascara without forming lumps of mascara on the eyelashes or on bristle portion 20.
  • the brush 10 is gripped by the cap 16 and dipped into a reservoir of liquid material, such as mascara.
  • the brush is withdrawn from the reservoir through a narrow orifice by a wiping action to obtain a distribution of mascara on bristle portion 20 suitable for applying to the eyelashes or other hair.
  • each of the plurality of bristles 30 generally has a central core 32 with a bore 38 therethrough, and spaced apart portions or flanges 33, 34, 35 and 36 extending outward from the periphery or exterior surface of the core.
  • the bore 38 may be a circular bore.
  • bore 38 is a generally oblong shaped bore.
  • the central core 32 has an overall square configuration, except for outwardly extending flange portions 33, 34, 35 and 36. As shown in Fig. 4 , flange portions 33, 34, 35 and 36 are formed on what would otherwise be the edge of the square shaped core. It should be understood that although four flanges are shown in Fig. 4 , the present invention encompasses embodiments that have two or more such flanges.
  • Flanges 33, 34, 35 and 36 are bent in the same direction about the periphery of central core 32.
  • the area along the periphery between adjacent pair of flanges 33, 34, 35 and 36 is area 37.
  • Each area 37 holds or retains mascara by surface tension.
  • each filament 26, and thus each bristle 30, is about 0.08 to about 0.18 mm.
  • the maximum cross sectional dimension is about 0.10 to about 0.15 mm.
  • the filaments 26 for each pair of bristles 30 shown in Fig. 4 may be obtained commercially from Dupont De Nemours Corporation.
  • a filament 50 has a central core 52 with a first pair of approximately identical curled flanges 53 and 55 radially extending in approximately opposite directions.

  • a filament 90 has a central core 92 with radially extending T-shaped flanges 93, 94, 95 and 96.
  • Flanges 93 and 95 extend from core 82 in approximately opposite directions and flanges 94 and 96 extend from core 92 in approximately opposite directions.
  • a filament 100 has a central core 102 with radially extending curled flanges 103, 104, 105 and 106. Approximately identical flanges 103 and 105 extend from core 102 in approximately opposite directions and approximately identical flanges 104 and 106 extend from core 102 in approximately opposite directions.
  • a filament 110 has a central core 112 with radially extending curled flanges 113, 114, 115 and 116. Approximately identical flanges 113 and 115 extend from core 112 in approximately opposite directions and approximately identical flanges 114 and 116 extend from core 112 in approximately opposite directions.
  • a filament 120 has a central core 122 with radially extending flanges 123, 124, 125 and 126.
