Abstract

An applicator for applying a cosmetic to eyelashes, comprising a shaft section or at least a coupling section and an applicator section, the applicator section being configured as an internally hollow cage for accommodating the cosmetic, which is substantially or completely closed in the circumferential direction, characterized in that the cage, in the direction perpendicular to its longitudinal axis, has a triangular cross section and comprises on at least one of its circumferential tips a number of passages that communicate with the interior of the cage and into which the eyelashes insert themselves during application.

First claim

The invention claimed is:

1. An applicator for applying a cosmetic to eyelashes, comprising:
a coupling section; and
an applicator section joined to the coupling section, the applicator section being configured as an internally hollow cage for accommodating the cosmetic, wherein the cage is substantially or completely closed in a circumferential direction and a proximal end face of the applicator section joined to the coupling section is completely closed, and the cage, in a direction perpendicular to a longitudinal axis of the applicator section, has a triangular cross section;
wherein the cage is formed by three carrier members that are attached to the closed proximal end face and extend in a direction substantially parallel to the longitudinal axis of the applicator section, with adjacent carrier members connected to each other through a plurality of spaced-apart ribs which form passages between the ribs, with each of the ribs extending from a base point on one carrier member, through an apex, to a base point on the adjacent carrier member; and
wherein a width of each rib measured in the direction parallel to the longitudinal axis of the applicator section decreases from the base points towards the apex wherein a spacing of two ribs adjacent to one another in the direction parallel to the longitudinal axis is greater than the width of each of the two adjacent ribs in the direction parallel to the longitudinal axis, by at least a factor of 1.5.

2. The applicator according to claim 1 , wherein the passages constitute at least 25% of the surface area that an enveloping jacket surface that would cover an entire surface area of the cage, including the carrier members, ribs, and passages between the ribs, possesses.

3. The applicator according to claim 1 , wherein a distal end face of the applicator section opposite the proximal end of the applicator section comprises an opening through which cosmetic is pushed into the interior of the cage during insertion of the applicator into a cosmetics storage container, wherein a cross-sectional surface area of the opening constitutes at least 50% of the surface area of the distal end face.

4. The applicator according to claim 1 , wherein at least a part of the carrier members is configured to be sufficiently strong to prevent permanent deformation of the carrier members when the cage passes through a wiper attached to a container into which the applicator is inserted and withdrawn during use.

5. The applicator according to claim 1 , wherein a transverse cross section of each of the carrier members is respectively greater than a transverse cross section of each of the ribs.

6. The applicator according to claim 1 , wherein a cross section of at least a plurality of the ribs has a greater width in a radial direction than in the direction parallel to the longitudinal axis.

7. An applicator for applying a cosmetic to eyelashes, comprising:
a coupling section; and
an applicator section joined to the coupling section, the applicator section being configured as an internally hollow cage for accommodating the cosmetic, wherein the cage is substantially or completely closed in a circumferential direction and a proximal end face of the applicator section joined to the coupling section is completely closed, and a cross section of the cage comprises, perpendicular to a longitudinal axis of the applicator section, at least one substantially V-shaped bulge having two surfaces disposed at an angle to each other of ≦110°, which protrudes outwards from the longitudinal axis in the circumferential direction,
wherein the cage is formed by three carrier members that are attached to the closed proximal end face and extend in a direction substantially parallel to the longitudinal axis of the applicator section, with adjacent carrier members connected to each other through a plurality of spaced-apart ribs which form passages between the ribs, with each of the ribs extending from a base point on one carrier member, through an apex, to a base point on the adjacent carrier member; and
wherein a width of each rib measured in the direction parallel to the longitudinal axis of the applicator section decreases from the base points towards the apex wherein the passages, viewed in the circumferential direction, extend without interruption over an arc that corresponds to an angle of at least 40°.

8. The applicator according to claim 7 , wherein the passages constitute at least 25% of the surface area that an enveloping jacket surface that would cover an entire surface area of the cage, including the carrier members, ribs, and passages between the ribs, possesses.

9. The applicator according to claim 7 , wherein a distal end face of the applicator section opposite the proximal end of the applicator section comprises an opening through which cosmetic is pushed into the interior of the cage during insertion of the applicator into a cosmetics storage container, wherein a cross-sectional surface area of the opening constitutes at least 50% of the surface area of the distal end face.

10. The applicator according to claim 7 , wherein at least a part of the carrier members is configured to be sufficiently strong to prevent permanent deformation of the carrier members when the cage passes through a wiper attached to a container into which the applicator is inserted and withdrawn during use.

11. An applicator for applying a cosmetic to eyelashes, comprising:
a coupling section; and
an applicator section joined to the coupling section, the applicator section being configured as an internally hollow cage for accommodating the cosmetic, wherein the cage is substantially or completely closed in a circumferential direction and a proximal end face of the applicator section joined to the coupling section is completely closed, and
wherein the cage comprises two carrier members that are attached to the closed proximal end face and extend in a direction substantially parallel to a longitudinal axis of the applicator section, and the carrier members are connected to each other through a plurality of spaced-apart ribs that extend from one carrier member to the other carrier member forming passages between the ribs that communicate with an interior of the cage and into which the eyelashes insert themselves during application, and the ribs are formed by a helical coil consisting of metal that is overmolded with plastic along with the carrier members wherein a transverse cross section of each of the carrier members is greater than a transverse cross section of each of the ribs.

12. The applicator according to claim 11 , wherein a cross section of at least a plurality of the ribs has a greater width in a radial direction than in the direction parallel to the longitudinal axis.
