Definitions

  • This invention relates to spiral mascara brushes.
  • a spiral mascara brush comprises a multiplicity of bristles each having opposed free ends, and means for fixedly mounting the bristles in a continuous spiral array such that the free ends of the bristles are disposed along a helix
  • the mounting means is an initially U-shaped wire, which is twisted into a light, axially rectilinear helix (after the bristles have been positioned between the legs of the U) to grip the bristles firmly at their midsections and to spread them into the aforementioned spiral array.
  • the bristle array which may, for example, be cylindrical (having bristles of uniform length from base to tip of the brush) or conical (having bristles or progressively shorter length toward the brush tip), is dimensioned to be inserted within a mascara container.
  • the wire or other mounting means projects beyond the base of the bristle array and is commonly embedded in a plastic shank projecting axially from the interior of a mascara container cap, so that when the cap is mounted in closed position on a container, the brush is disposed inside the container with the bristles immersed as aforesaid.
  • Brushes of this type are well known and widely used at the present day.
  • One such mascara is described in GB-A-1,221,919. in this document an elongate brush with radially extending bristles is withdrawn from the container through an orifice that causes the mascara to impregnate the brush.
  • a spiral mascara brush The conventional purpose of a spiral mascara brush is to apply mascara to a user's eyelashes, i.e. to pick up and transport mascara from the mascara container and to deposit the transported mascara on the eyelashes.
  • the bristles must be soft (relatively low in flexural strength), because stiff bristles do not satisfactorily pick up, transport, and deposit mascara.
  • An illustrative example of a bristle suitable for applying mascara is a nylon 6/12 fiber commercially available from E.I. duPont de Nemours & Co under the trade name "Tynex", having a diameter of 7.62 x 10 -3 cm (0.003 inch) ⁇ 1.27 x 10 -3 cm (0.0005 inch) ⁇ 15%.
  • mascara as applied to eyelashes tends to deposit unevenly, in the form of clumps.
  • the applied mascara must be combed through the lashes.
  • Mascara brush bristles sort enough to apply mascara are too soft to comb eyelashes; when pressed against the lashes, they simply flex and do not penetrate the lashes as required to effect combing.
  • the present invention provides the spiral mascara brush defined by claim 1.
  • flexural strength refers to resistance to bending; thus, a bristle of greater flexural strength is stiffer (less flexible) than a bristle of lesser flexural strength.
  • the requisite difference in stiffness (flexural strength) between the bristles of the first and second quantities may be achieved by using bristles of different diameters and/or different materials.
  • the bristles of both quantities may be nylon fibers, with the first-quantity bristles having a diameter of about 6.35 x 10 -3 cm (0.0025 inch) and the second-quantity bristles having a diameter of about 0.015cm (0.006 inch).
  • the first-quantity bristles may be nylon fibers and the second-quantity bristles may be polyester fibers.
  • the two quantities of bristles may also differ in color, to enable the user to recognize and distinguish them.
  • a spiral mascara brush 10 including a brush head 11 and a cap 12 adapted to fit over and close the open top of a conventional mascara container (not illustrated).
  • the brush head comprises a multiplicity of bristles 14 each having opposed free ends, and means 16 for fixedly mounting the bristles in a continuous spiral array such that the free ends of the bristles are disposed along an axially rectilinear open helix extending continuously from the base 18 to the tip 20 of the brush head.
  • the bristle-mounting means 16 is a metal wire having a midpoint located at the brush tip 20 and bent at that midpoint to provide two legs which are twisted together into a tight helix about a rectilinear axis coincident with the axis of the aforementioned open helix.
  • the bristles of the brush are firmly gripped at their midsections between the twisted legs of the wire 16 so as to be held in the described spiral array, with the two ends of each bristle projecting equidistantly from the wire 16 in directions substantially perpendicular to the helix axis.
  • the brush head is shown as having a conical configuration tapering toward the tip 20; i.e., the constituent bristles of the spiral array are of progressively shorter length toward the tip.
  • the helically twisted legs of the wire (mounting means) 16 extend for some distance beyond the base of the array of bristles.
  • This bristle-free terminal portion of the wire is fixedly embedded in a plastic shank 22 which projects axially from the interior of the mascara container cap 12.
  • An internally threaded skirt portion 24 of the cap concentrically surrounds the extremity of the shank remote from the bristles, in spaced concentric relation thereto, and opens toward the bristles.
  • the brush is, of course, appropriately dimensioned for such insertion as well as for application of mascara to a user's eyelashes.
  • the length of the array of bristles (from tip 20 to base 18) is 3.175cm (1.250 inch), with a diameter of 0.953cm (0.375 inch) at the base and 0.475cm (0.187 inch) at the tip, and the overall length of the projecting brush, from the open end of the skirt 24 to the brush tip 20, is 8.48cm (3.3340 inches).
  • the brush 10 is generally conventional, exemplifying spiral mascara brushes heretofore known and used to apply mascara to eyelashes.
  • a conventional brush of this type has a spiral array of bristles 14 constituted entirely of bristles of an essentially uniform flexural strength, which is sufficiently low for satisfactory performance of the operations of picking up mascara from a mascara container while the bristles are immersed therein, transporting the mascara from the container to a user's eyelashes, and depositing the transported mascara on the eyelashes.
  • the spirally arranged multiplicity of bristles 14 in the brush of the present example consists essentially of two sorts of bristles differing from each other in flexural strength, viz.
  • first-quantity bristles having a flexural strength adapted to apply mascara to a user's eyelashes and a second quantity of bristles having a different and substantially greater flexural strength adapted to comb the applied mascara through the eyelashes.
  • first-quantity bristles will sometimes be referred to herein as "soft” bristles and the second-quantity bristles will sometimes be referred to herein as "stiff" bristles.
  • Fig. 2 which is a simplified schematic representation of a fragmentary portion of one turn of the spiral array of bristles 14 as seen from the same view direction as Fig. 1)
  • the soft and stiff bristles are randomly intermingled throughout the entire length of the spiral array. More particularly, the soft or first-quantity bristles 26 (shown as black bristles) are interspersed with stiff or second-quantity bristles 28 (shown as white or neutral-coloured bristles), each quantity of bristles being present in a proportion effective to perform its respective (applying or combing) function.
  • the desired results are achieved when at least about 30% of the total number of bristles present in the spiral array are soft bristles 26 and at least about 10% are stiff bristles 28; preferably, as indicated in Fig, 2 a majority of the bristles are soft bristles.
  • the bristles of both quantities may be fabricated of the same material but may differ in diameter to provide the requisite respective flexural strengths, the soft bristles being smaller in diameter than the stiff bristles,
  • the soft bristles 26 may be made of nylon, with an individual bristle diameter of 6.35 x 10 -3 cm (0.0025 inch), and the stiff bristles 28 may likewise be made of nylon, but with an individual bristle diameter of 0.015 cm (0.006 inch).
  • the soft and stiff bristles may be made of respectively different materials which, for a given bristle diameter, have respectively different flexural strengths; thus, as a further example, the soft bristles may be nylon fibers of 6.35 x 10 -3 cm (0.0025 inch) diameter and the stiff bristles may be polyester fibers of the same (or greater) diameter.
  • the brush of Fig. 2 is used in much the same way as a conventional spiral mascara brush. Ordinarily, it is enclosed within a mascara container, with the array of bristles 14 (i.e., including both bristles 26 and bristles 28) immersed in the mascara and the cap 12 threaded in closed position on the neck of the container.
  • the cap is unscrewed and removed, withdrawing the brush from the container, mascara is transported on the brush (predominantly by the soft bristles 26), and is deposted therefrom onto the user's eyelashes as the brush is brought manually into contact with the eyelashes.
  • the mascara may deposit as clumps, owing to its high viscosity, but as the brush is manipulated with a combing motion against the eyelashes the stiff bristles 28 comb through the eyelashes to distribute the applied mascara. Thereafter, the brush is reinserted into the mascara container and the cap is returned to container-closing position.
  • the brush 10 having randomly intermingled sort and stiff bristles thus serves both to apply the mascara and to distribute it by combing through the lashes, in an essentially unitary or integrated manipulative operation requiring only a single implement, which is protected by being enclosed in the mascara container when not in use.
  • the presence of bristles of both kinds (soft and stiff) is essential to the attainment of these results, because bristles sort enough for satisfactory mascara application are too sort to provide effective combing action.
  • the spiral array of bristles 14 mounted on the twisted wire 16 includes two contiguous portions respectively designated 30 and 32, disposed in tandem along the length of the array.
  • the same types of bristles 26 and 28 as are intermingled in the brush of Fig. 2 can be used, respectively, to constitute the differentiated portions 30 and 32 of the brush of Fig. 3.
  • the brush of Fig. 3 is used much in the manner of the brush of Fig. 2, except that the portion 30 is first brought into contact with the eyelashes to apply mascara, and the portion 32 is then brought into contact with the lashes to comb the mascara therethrough. Again, as in the case of the Fig. 2 brush, both application and combing are performed by a single implement, which is protected (when not in use) by the mascara container.
  • Fig. 4 illustrates a modification of the embodiment of Fig. 3 wherein the sort, mascara-applying bristle portion 30' is located adjacent the tip, and the stiff, lash-combing bristle portion 32' is located adjacent the base, of the spiral array of bristles; also, in Fig. 4, the bristle array 14' is shown as cylindrical (formed with bristles of uniform length throughout its extent) rather than conical in shape. As will be appreciated, other arrangements of alternating soft and stiff bristle portions are possible, such as (for example) a three-portion spiral array of bristles with a short, stiff, combing portion at each end and a longer, soft, applying portion between them. Moreover, the cylindrical configuration is equally suitable or the randomly intermingled array of soft and stiff bristles represented by Fig. 2.
  • the soft and stiff bristles may be differentiated by color as well as by flexural strength, one exemplary color difference (black soft bristles, neutral or white stiff bristles) being represented in Figs. 2-4.
  • This color differentiation initially indicates to the user whether the brush is of the intermingled soft and stiff bristle type (Fig. 2) or of the differentiated soft and stiff portion type (Figs. 3 and 4), and, in the latter case, shows the location of the combing portion. Even though, in use, such color differentiation may be more or less obscured by mascara coating the brush, the initial indication assists the user in understanding how to manipulate the brush. In particular, when the brush is initially packaged outside the mascara container, i.e. for sale (with the container closed by a temporary cap), the color differentiation is clearly visible prior to the first insertion of the brush into the container.
  • Brushes embodying the invention may be manufactured in a generally conventional way, as illustrated schematically in Fig. 5, except for the inclusion (and appropriate relative positioning) of both soft and stiff bristles in the bristle feed.
  • the wire 16 is initially in the form of a U between which the bristles 14 are fed transversely; then the legs of the wire are twisted (arrows 36) about longitudinal axis 38 to grip the midsections of the bristles and spread the bristles into the spiral array of Fig. 1.
  • the bristles as fed between the wire legs include soft and stiff bristles randomly intermingled to produce the brush of Fig. 2, or differentiated into soft and stiff portions to produce the brushes of Figs. 3 and 4.
