Definitions

  • the present invention relates to brushes for applying a composition to the eyelashes and the eyebrows, and also to packaging and applicator devices including such a brush.
  • the invention relates more particularly to a brush comprising rows of bristles that are made by being molded integrally with a core, such brushes sometimes also being known as “combs” or "injection-molded brushes”.
  • Application EP 1 175 847 Al describes an applicator comprising an arrangement of bristles that are fitted on a non-twisted support, the arrangement comprising groups of bristles that cross when the applicator is observed transversally to its longitudinal axis.
  • the bristles being fitted on the core, it is difficult to provide them other than on one side only of the core, or on two opposite sides.
  • such an applicator does not look or behave like conventional mascara brushes having rows of bristles that are distributed all around the core .
  • EP 1 543 741 and EP 1 726 234 disclose molded applicators having bristles on one side of a support, the bristles ' extending towards the distal end and towards the proximal end of the applicator.
  • Application EP 1 611 817 Ax discloses a molded applicator that, in one particular embodiment, has bristles of a row that extend alternatingly towards the distal end and towards the proximal end of the applicator.
  • Application EP 1 070 467 A2 discloses combs having bristles that cross when the combs are observed from the side .
  • a brush comprising: a core that is made by molding and that extends along a longitudinal axis; and a plurality of rows of bristles that are also made by molding, having bases that are distributed over the periphery of the core so as to offer novel possibilities for applying makeup, and in particular so as to make it possible to control the flexibility of the bristles during application, and also while passing through the wiper member, if one exists, is provided.
  • the bristles are disposed so that there exists at least one projection axis orthogonal to the longitudinal axis of the core for which the projected images of the bristles of a first row cross the projected images of the bristles of a second row.
  • the bristles of the first row appear to cross the bristles of the second row.
  • Two bristles for which a crossing is observed may have respective longitudinal axes that are never parallel.
  • the bristles need not touch one another.
  • the offset between the free ends of the two bristles may lie in the range 0.1 millimeters (mm) to 5 mm, e.g. in the range 0.2 mm to 0.8 mm, in particular in the range 3 mm to 4 mm. Bristles that are sufficiently close together enable said bristles to make contact with the eyelash simultaneously during application.
  • the first and second rows are adjacent without an intermediate row between them.
  • the number of first rows is greater than or equal to three, e.g. equal to 4 , 5, 6, 7, or 8.
  • the distribution of the first rows all around the core may optionally be regular.
  • the bristles of at least three, or even four, first rows may extend in different directions around the longitudinal axis of the core.
  • each of the first rows there may exist at least one second row making it possible to observe, in side view, a crossing of the bristles, as defined above.

  • At least 4, 5 or 6 bases may be present in a cutaway view taken perpendicularly to the longitudinal axis of the core.
  • a brush of the invention presents numerous advantages. Initially, the slope of the bristles imparts flexibility thereto during application, and also while passing through the wiper member, in embodiments so provided. The flexibility may be adjusted easily during manufacture by sloping the bristles to a greater or lesser extent.
  • the crossing of the bristles defines spaces that are suitable for receiving the eyelashes during application.
  • the spaces may have a V-notch that is favorable to catching the eyelashes, and to smoothing the composition over the eyelashes.
  • the slope of the bristles may promote the accumulation of composition between the bristles and the core, which may improve the performance of the brush in terms of loading the eyelashes with composition.
  • the fact that a bristle slopes may also encourage composition to accumulate on a side facing away from the core. Such an accumulation may enable the eyelashes that come into contact therewith to be well loaded.
  • the bristles may not be touching each other. This feature enables the bristles to take up the eyelashes between a bristle and the core or between two bristles, in order to treat them.
  • the bristles are such that a eyelash may be taken up under a bristle, i.e. between abristle and the core.
  • the contact of the brush with the eyelashes may be gentle and without pinching, the sloping of the bristles imparting cushioning properties thereto.
  • the invention reduces the number of brushes to be made having different configurations. .
  • the sloping of the bristles may also alter the distribution of the free ends of the bristles at the surface of the brush, e.g. so as to obtain a density of free ends that is higher at the front of the brush (the distal end) than at the rear (the proximal end ⁇ .
  • the bristles of a single row may be identical along the row or they may vary in size, e.g. diameter, and/or length defined between the base and the distal end of the bristles; slope; shapes; and/or spacing.
  • the bases of the bristles of a single row may optionally be in alignment.
  • the variation in the slope may be longitudinal, i.e. may relate to the angle relative to the longitudinal axis, and/or it may be lateral, i.e. may relate to the angle relative to the normal to the core in a plane that is perpendicular to the longitudinal axis.
  • the bristles may be rectilinear, or in a variant may be curved.
  • a bristle may be curved in two axis, i.e. around two axis of curvature which are not parallel to each other.
  • a bristle may also be twisted.
  • the rows may comprise double bristles, or even triple bristles or quadruple bristles .
  • the core may have a cross -section that is constant along the brush, or it may vary. Variation in the cross- section of the envelope surface of the brush, along said brush, may be due to a variation in the section of the core, the length of the bristles being constant, for example .
  • At least a fraction of the bristles of the first row may present slopes relative to the longitudinal axis of the core that vary along the first row. For example, slope relative to the longitudinal axis of the core may increase progressively and then decrease, while going from one longitudinal end of the core to the other. The slopes may possibly be reversed. Varying slopes make it possible to take account of the fact that users may favor using certain portions of the brush to treat the eyelashes at the corner of the eye, for example. This may also enable the bristles to be made more flexible where the stresses during wiping are smaller, or on the contrary greater, depending on the desired result.
  • bristles that slope more steeply towards the distal end of the brush, on going towards the distal end of the brush, since that makes it easier to use the brush with its longitudinal axis oriented substantially perpendicularly to the set of eyelashes, which may be desirable for treating the eyelashes at the corner of the eye.
  • the heights of bristles of the second row at which the cross-over with the bristles of the first row can be seen may also vary, the bristles of the second row being shorter where they cross the bristles that slope more steeply, for example. That makes it possible to avoid the bristles of the second row projecting too much relative to the bristles of the first row, if they are not sloping, or slope only a little. That makes it possible to avoid the bristles of the second row unduly hindering gentle application.
  • the bristles of the second row may present slopes relative to the longitudinal axis of the core that vary along the second row. Varying slopes make it possible to have different application properties at different locations of the brush.

Abstract

La présente invention concerne une brosse permettant d'appliquer une composition sur les cils ou les sourcils. La brosse comprend : une âme qui est faite par moulage et qui s'étend le long d'un axe longitudinal (X) ; et une pluralité de rangées de soies qui sont également faites par moulage, possédant des bases qui sont réparties sur la périphérie de l'âme, les soies étant disposées de sorte qu'il existe au moins un axe de projection orthogonal à l'axe longitudinal de l'âme pour lequel les images projetées des soies d'une première rangée croisent les images projetées des soies d'une seconde rangée.
