Definitions

  • the invention is in the field of cosmetic applicators, specifically hair product applicators that combine a non-molded fiber brush and a molded brush for making up the eyelashes.
  • Cosmetic applicators for the hair of the head must perform two broad functions, which we call loading and grooming.
  • Loading means that the applicator takes up a dose of product and deposits it onto an application surface, such as eyelashes. Thereafter, it is typical for the same cosmetic applicator to be used for grooming the eyelashes.
  • the first step, loading creates a volumizing effect
  • the second step, grooming may include smoothing the product evenly over the lashes, separating the individual lashes, curling the lashes, and/or creating a lengthening effect. Because the function of loading product is different from the function of grooming the hair, a single cosmetic applicator may not perform both functions satisfactorily.
  • an applicator that has an applicator head that comprises at least two different types of bristles, one type being relatively soft and flexible, the other type being less soft and less flexible. Sometimes multiple types of bristles have been mixed together throughout the applicator head in the hope of getting the best of both. Alternatively, it is also known to divide an applicator head into zones, each zone having one type of bristle.
  • U.S. Pat. No. 7,231,926 discloses a mascara applicator that comprises an application brush part and an arrangement brush part. We will discuss U.S. Pat. No. 7,231,926, which we consider to be the closest prior art.
  • the applicator of U.S. Pat. No. 7,231,926 comprises a grip ( 6 ), a rod ( 2 ) extending form the grip, and a “fixing stand” ( 40 ) that depends from the rod ( 2 ).
  • the arrangement brush part (or comb, 4 ) is implemented as one or more columns of injection molded teeth that radiate from the fixing stand ( 40 ).
  • the application brush part ( 3 ) may be comprise an application portion ( 7 ) of bristles that radiate from a twisted wire rod ( 21 ), and occupy the space between the “fitting hole” ( 42 ) and the “fitting recess” ( 43 ).
  • the application brush part In order for the application brush part to fit into the space between the “fitting hole” and the “fitting recess”, the application brush part is provided with an angular section ( 31 ) of 30°-120° that is devoid of bristles (see FIG. 3 ).
  • the size of this gap should be at least as large as the radius of the fiber brush.
  • the gap should be a minimum 4 mm, and for a brush with an overall diameter of 10 mm, the gap should be a minimum of 5 mm.
  • the manner in which the application brush part ( 3 ) is assembled to the fixing stand ( 40 ), means that the bristles of the application portion ( 7 ) cannot extend to the distal tip of the applicator. This is a real disadvantage when trying to apply mascara to the eyelashes that are toward the inner canthus of the eye.
  • the bristles of the application portion ( 7 ) must be relatively flexible. Fiber bristles may be sufficiently flexible, but even that is no guarantee that the bristles will not be damaged when they are crushed together to pass through the fitting hole.
  • FIG. 2 of U.S. Pat. No. 7,231,926 gives the distinct impression that the diameter of the fitting hole ( 42 ) is very nearly equal to the diameter of the twisted wire rod ( 21 ), so the bristle portion ( 7 ) is really squeezed.
  • the application brush part ( 3 ) is provided with an angular section ( 31 ) of 30°-120° that is devoid of bristles (see FIG. 3 ). Consequently, the angular size of the arrangement brush part ( 4 ) is limited to 30°-120°.
  • an applicator head for a cosmetic applicator comprises a molded brush portion (adapted for grooming) to which is mounted a non-molded, fiber brush (adapted for loading).
  • the molded brush portion comprises relatively harder, relatively less flexible, injection molded bristles, while the non-molded brush portion comprises relatively softer, more flexible fiber bristles.
  • the assembled applicator head has a distal end that is covered with the relatively harder bristles to facilitate grooming those eyelashes that are near the inner canthus of the eye.
  • the molded and non-molded brush portions fill and angular sector of 360°.
  • the molded brush portion fills an angular sector of 180°-200°, which is significantly greater than the 30°-120° of the arrangement brush part ( 4 ) of U.S.
  • the non-molded brush portion fills an angular sector of 160°-180°.
  • the snap fit assembly method of the non-molded brush portion into the molded brush portion eliminates the need for a gap between the two brushes, along with any unwanted play, so that the non-molded brush portion cannot slide back and forth with respect to the molded brush portion.
  • FIGS. 1-3 depict a prior art applicator disclosed in U.S. Pat. No. 7,231,926.
  • FIGS. 4A and 4B depict a mascara applicator according to the present invention.
  • FIGS. 5A and 5B depict one embodiment of a molded brush portion of an applicator head according to the present invention.
  • FIGS. 6A and 6B depict one embodiment of a non-molded brush portion of an applicator head according to the present invention.
  • FIGS. 7A and 7B show the a non-molded brush portion being assembled to a molded brush portion.
  • FIG. 8A shows an assembled applicator head according to the present invention.
  • FIG. 8B is a cross sectional view of the applicator head of FIG. 8A .
  • a mascara applicator according to the present invention comprises a handle ( 11 ), an extended rod ( 12 ), and an applicator head ( 13 ) in the usual relationship of these elements. That is, the handle serves as a closure for a container of mascara product. Typically, the closure has screw threads ( 11 a ) on its inner surface for mating to a threaded container.
  • the extended rod is connected to and depends from an inner surface of the handle, and the applicator head depends from the distal end ( 12 a ) of the rod.
  • the rod may be hollow, and able to receive the stem ( 14 a ) of the applicator head into itself.
  • An applicator head according to the present invention has two main parts: a molded brush portion ( 14 ) and the non-molded portion ( 15 ).
  • the molded brush portion ( 14 ) comprises a stem ( 14 a ) and a main body ( 14 f ).
  • the stem may be formed as a generally cylindrical member having proximal ( 14 b ) and distal ( 14 c ) ends, and a hollow space ( 14 d ) that opens onto the distal end of the stem, and onto the side wall ( 14 e ) of the stem.
  • the side wall of the stem is devoid of bristles or other grooming features, and is generally smooth, so that the stem is able to join to the distal end ( 12 a ) of the rod ( 12 ), as described above.
  • the main body ( 14 f ) comprises an approximately semi-cylindrical member ( 14 g ), an opened proximal end ( 14 h ), and a closed distal end ( 14 i ).
  • the semi-cylindrical member ( 14 g ) defines a hollow space ( 14 j ) that connects to the opened proximal end ( 14 h ) and to a groove ( 14 k ) located in the closed distal end ( 14 i ) of the main body (see FIG. 8B ).
  • the opened proximal end ( 14 h ) is integrally molded to the opened distal end ( 14 c ) of the stem ( 14 a ), such that the hollow space ( 14 j ) of the semi-cylindrical member and the hollow space ( 14 d ) of the stem are contiguous, as shown.
  • the semi-cylindrical member ( 14 g ) is approximately semi-cylindrical, we mean that the semi-cylindrical member occupies an angular space of approximately 180°-200°.
  • the distal end ( 14 i ) of the main body ( 14 f ) occupies a complete 360° around longitudinal axis A-A, while the proximal end ( 14 h ) may occupy between about 200° and 270°.
  • the semi-cylindrical member ( 14 g ) may taper toward the closed distal end ( 14 i ).
  • the outside surface of the semi-cylindrical member features a multitude of molded bristles ( 14 l ), as does the closed distal end ( 14 i ) of the main body.
  • the proximal end ( 14 h ) of the main body may or may not comprise bristles.
  • the bristles ( 14 l ) of the semi-cylindrical member ( 14 g ) are regularly arranged in columns ( 14 p ) that extend down the semi-cylindrical member, parallel to the longitudinal axis (A-A) of the main body ( 14 f ).
  • Each column of bristles may typically comprise from 5 to 50 bristles, preferably from 10 to 40, more preferably from 20 to 35 bristles.
  • the semi-cylindrical member of FIG. 5A has 23 bristles in a longitudinal column.
  • the semi-cylindrical member may preferably comprise from 4 to 10 columns of bristles. More preferred are 7, 8 or 9 columns of bristles.
  • the semi-cylindrical member of the main body ( 14 f ) has 9 columns of bristles extending longitudinally along the semi-cylindrical member. Furthermore, in preferred embodiments, bristles ( 14 l ) of the semi-cylindrical member are regularly arranged in rows, each row lying on a circumference of the semi-cylindrical member, in a plane that is perpendicular to the longitudinal axis of the main body.
  • the bristles ( 14 l ) of the semi-cylindrical member ( 14 g ) of the main body ( 14 f ) typically extend radially from the longitudinal axis of the main body, and all of the bristles in a single column are parallel to each other.
  • the bristles of the distal end ( 14 i ) of the main body extend in various directions.
  • the bristles may comprise flat and/or rounded portions, and the horizontal cross section of the bristles may be any conceivable shape, only limited by the ability to mold the main body.
  • bristles that have a horizontal cross section that is shaped as a circular segment that has an arc that ranges from about 160° to no more than 180°, and whose radius decreases as you move from base to tip.
  • Such bristles have a semi-conical profile comprised of a flat face and a curved face.
  • the bristles would have a rounded tip.
  • the remainder of each bristle may be shaped to have one or more depressions, one or more protrusions, or both on the curved face of the semi-conical bristle, while the flat face has no such features.
  • each semi-conical bristle has at least two depressions and/or protrusions located on its curved surface.
  • a bristle may have one or more perforations that pass through the bristle from the flat face to the curved face.
  • the manufacture of such bristles was described in U.S. Pat. No. 9,326,584 which is hereby incorporated by reference in its entirety.
  • the molded bristles of the molded brush portion ( 14 ) do not have to be all the same height.
  • Exemplary materials that can be used in the present invention to create the molded brush portion ( 14 ) include, but are not limited to: silicone elastomers, thermoplastic elastomers (such as, for example, styrene-ethylene-butylene-styrene block copolymer—SEBS), vinyl elastomers (EVA), thermoplastic polyester elastomers (Hytrel® from Dupont de Nemours), thermoplastic polyurethane elastomers (Pellethane® from Dow Plastic), Nitrile, and EPDM. Hardness of the chosen material preferably ranges from about 35 MPa (35 shore D Hytrel® from Dupont de Nemours) to about 1180 MPa (82 shore D Hytrel®). In general, harder, less flexible materials will be more suitable for the molded brush portion ( 14 ), which is intended to spread and declump a thick mascara product, and separate and lengthen the eyelashes.
  • silicone elastomers such as, for example, styren
  • the non-molded brush portion ( 15 ) comprises a twisted wire core ( 15 a ) that supports a multitude of fiber bristles ( 15 e ) in a predetermined arrangement, such as helical.
  • the proximal ( 15 b ) and a distal ( 15 c ) ends of the twisted wire core are devoid of bristles.
  • the length of the distal end that is devoid of bristles is, preferably, about 2-5 mm.
  • the length of the proximal end of the twisted worn core that is devoid of bristles is, preferably, about 3-6 mm.
  • the multitude of bristles define an approximately semi-cylindrical bristle envelope that occupies an angular space of approximately 160°-180°.
  • the non-molded brush portion may be fashioned in the usual manner of twisted wire core brushes, but thereafter, all of the bristles filling an angle of 180°-200° are cropped close to the wire core.
  • the wire core ( 15 a ) may be fashioned from stainless steel having a diameter from 0.5 to 1 mm.
  • the bristles ( 15 e ) of the non-molded brush portion ( 15 ) may be nylon, hollow or solid, and typically from 0.1 to 0.5 mm.
  • the number of fiber bristles may vary, but will typically be between 250 and 500.
  • the bristles of the non-molded brush portion do not have to be all the same height.
  • the molded ( 14 ) and non-molded ( 15 ) brush portions are fashioned separately, and subsequently assembled.
  • the proximal end ( 15 b ) and distal end ( 15 c ) of the wire core ( 15 a ) are devoid of bristles ( 15 e ).
  • the first step in assembling the non-molded brush portion ( 15 ) to the molded brush portion ( 14 ) is to insert the distal end ( 15 c ) of the non-molded brush portion into the groove ( 14 k ) of the molded brush portion, the length of the groove being at least as long as the distal end ( 15 c ) of the wire core (i.e. 2-5 mm). Then, as shown in FIG.
  • the wire core ( 15 a ) is brought into the hollow space ( 14 j ) of the semi-cylindrical member ( 14 g ) of the molded brush portion ( 14 ), and the proximal end ( 15 b ) of the non-molded brush portion comes to rest in the hollow space ( 14 d ) of the stem ( 14 a ), the hollow space being at least as long as the proximal end ( 15 b ) of the wire core (i.e. 3-6 mm).
  • Two views of a fully assembled applicator head are shown in FIGS. 8A and 8B .
  • the hollow space ( 14 d ) of the stem ( 14 a ) may be provided with one or more flexible ( 14 m ) tabs that allow the proximal end ( 15 b ) of the non-molded brush portion ( 15 ) to be forced into the hollow space of the stem, but that prevent accidental removal therefrom.
  • the longitudinal axis (A-A) of the molded brush portion ( 14 ) is parallel to the longitudinal axis (B-B) of the non-molded brush portion ( 15 ).
  • the molded brush portion and the non-molded brush portion fill and angular sector of 360°.
  • the molded brush portion fills an angular sector of 180°-200°, which is significantly greater than the 30°-120° of the arrangement brush portion ( 4 ) in U.S. Pat. No. 7,231,926.
  • the greater angular size of the comb portion provides better grooming of the lashes, especially curling.
  • the distal end ( 14 i ) of the assembled applicator is covered with the bristles to facilitate making-up those eyelashes that are near the inner canthus of the eye. This feature is missing from the applicator of U.S. Pat. No. 7,231,926, which has no bristles on its distal end.
