Definitions

  • This invention relates to a cosmetic applicator suitable for applying such liquid cosmetics as lip gloss, liquid rouge, eye liner, and enamel. More particularly, the invention relates to a cosmetic applicator equipped with a brush section which is integrally formed at the leading end of the shaft of the applicator and has a multiplicity of integrally molded plastic fibers.
  • Patent Document 1 listed below discloses a lip gloss applicator equipped with a brush section having very thin plastic fibers called bristles which are integrally bundled together and then securely swaged to the applicator shaft by means of a metal piece.
  • Patent Documents 2 and 3 disclose cosmetic applicators for applying liquid cosmetic such as enamel, which has a multiplicity of integrally molded plastic brush fibers at the leading end of the applicator shaft.
  • PATENT DOCUMENT 1 JPA LAID OPEN 2003-169713
  • PATENT DOCUMENT 2 JUM LAID OPEN H6-13714
  • PATENT DOCUMENT 3 JPA LAID OPEN 2004-196371
  • Patent Document 1 has a problem (referred to as first problem), however, in that it is costly due to the fact that it requires multiple steps for fabricating brush fibers and integrating them to a bundle.
  • Patent Documents 2 and 3 can be advantageously molded integral with the applicator shafts from cheap materials in fewer steps.
  • the prior art concerns cosmetic applicators for applying enamel to nails, so that their brush fibers require certain stiffness and must be made of a relatively hard plastic resin.
  • the brush fibers of these applicators are too stiff and thick for use with lip gloss, and unfortunately they have rectangular or triangular transverse cross sections and angulated tips. As a consequence, they may hurt lips when used to apply lip gloss. This is a second problem pertinent to the prior art applicators.
  • the inventors of the present invention are motivated to provide a cosmetic applicator having a brush section that can be manufactured from a relatively cheap soft plastic resin in a fewer steps, and can be securely fixed to the leading end of a relatively hard resin applicator shaft, thereby providing a handleable yet tender cosmetic applicator, non-hurtful to lips.
  • this applicator can solve the first problem.
  • the brush of the inventive cosmetic applicator can be made of a much thinner tapered plastic resin fibers than those of the Patent Documents 2 and 3, with their transverse cross sections and tips rounded to prevent lip injury (second problem).
  • the inventors of the present invention made trial products and has verified in repeated tests that the inventive cosmetic applicator has overcome the first and second problems mentioned above.
  • the applicator In the process of developing a new type of cosmetic applicators (especially brush sections) the inventors encountered a new problem though, as described below. That is, the applicator has a certain disadvantage in a case where the brush fibers of the brush have the same thickness even if they are relatively soft. If the brush fibers are too thick, the brush section as a whole becomes too stiff, which is convenient for lip gloss application, but can hurt lips. On the other hand, if the brush fibers are too thin, the brush section as a whole becomes too soft, which can prevent lip injury but creates a third problem that the applicator is difficult to use as a lip gloss applicator.
  • the inventors made trial products and has verified through tests that in fact this configuration can overcome the third problem.
  • a cosmetic applicator having a brush section connected to the leading end of the applicator shaft, the brush section having plastic brush fibers each having a round cross section and a rounded tip, so that the brush will not hurt the facial skin of a user. It is another object of the invention to provide a convenient cosmetic applicator for applying a liquid cosmetic, the applicator having a brush consisting of thick brush fibers mixed with thin brush fibers such that the brush has a sufficient stiffness needed for a liquid cosmetic applicator but has a sufficient softness not to hurt facial skin.
  • a cosmetic applicator as defined in claim 1, having:
  • the applicator shaft is preferably made of a fairly hard plastic resin from the point of handleability of the applicator.
  • the fibers of the brush for applying a cosmetic to facial skin are preferably made of a relatively soft plastic resin not to hurt the facial skin of the user.
  • the applicator shaft is preferably selected from a first group of relatively hard plastic resins including, for example, polypropylene, PBT, POM, or a little harder PA (nylon), while the brush fibers are preferably selected from a second group of relatively softer plastic resins including, for example, polyethylene, a little softer PA, PET, and elastomers.
  • each of the soft brush fibers is preferably thin and tapered and has a round cross section and a rounded tip, so that the brush will not hurt the lips or facial skin of the user.
  • the second of the prior art problems is solved by the present invention. It should be noted that although the brush fibers are made of a relatively soft plastic resin, the handleablity of the applicator is not lost due to the fact that the applicator shaft is made of a rather hard plastic resin.
  • the brush of claim 1 may include thick brush fibers and thin brush fibers mixed together, as defined in claim 2.
  • Thin brush fibers have poor handleability for cosmetic application in that they are too soft to draw in outline. But they will not hurt lips nor facial skin.
  • thick fibers are stiff and convenient to draw in outline with cosmetic, though they can hurt lips and facial skin.
  • the stiffness of the brush as a whole can be varied.
  • the stiffness of the entire brush can be optimized for desired handleability and softness of applicator not to hurt lips and facial skin. In this way the third problem is solved.
  • the applicator of claim 2 may be configured such that the thick and thin brush fibers are distributed at a substantially uniform density, as defined in claim 3.
  • the applicator of claim 2 may be configured such that thin brush fibers are arranged in an inner area of the brush and the thick brush fibers in an outer area surrounding the thinner fibers, as defined in claim 4.
  • the cosmetic applicator of claim 2 may be configured such that the thick brush fibers are arranged in an inner area of the brush and the thin brush fibers in an outer area surrounding the thinner fibers, as defined in claim 5.
  • the outer portion of the brush consists of soft (or thinner) fibers, mainly soft outer portion of the brush touches lips and facial skin while applying a cosmetic.
  • the brush of a cosmetic applicator in accordance with claim 1 of the invention can be manufactured from a cheap material in a simple process.
  • the brush fibers are not only made thin and tapered but also made to have a round cross section and a rounded tip, the brush will not hurt lips nor facial skin of a user.
  • the applicator by providing the applicator with a shaft made of a relatively hard plastic resin, the applicator is made handeable for smooth application of a cosmetic.
  • the proportion of the thick brush fibers to thin brush fibers can be altered to vary the stiffness of the brush so that the applicator has both preferred stiffness and softness that meets varied needs of cosmetics users.
  • the stiffness and softness of the brush can be optimized to obtain a handleable and tender applicator.
  • the brush can properly deform to follow the facial configuration without bending excessively, so that the applicator is easy to draw in outline with a cosmetic.

  • the stem portion 36 of the shaft 30 is swaged with dowels 38 at multiple circumferential positions near the leading end of the stem 36 so as to securely fix the base 42 to the shaft 30.
  • the helve or the shaft 30 of the applicator is made of a fairly hard plastic resin (polypropylene for example), while the brush 44 of the brush section 40 is made of a fairly soft plastic resin (polyethylene for example) so as not to hurt lips.

Formed near the lower end of the middle inner plug 14 is a wiper 15 that protrudes from the inner surface of the middle inner plug 14 for scraping off superfluous liquid gloss adhering to the stem portion 36 of the shaft 30 or brush 44 as the shaft 30 is withdrawn from the container 10.
  • the brush 44 of the brush section 40 consists of 27 brush fibers (11 mm in length) spaced apart at substantially equal distance, each brush fiber having a circular transverse cross section and rounded tip, and being tapered (with the outer diameter being 0.4 mm at the root thereof, 0.2 mm at the tip).
  • Each of the brush fibers extending from the forefront face 42a of the base 42 has a total length of 9 mm and outer diameter of 3.4 mm.
