Applicator for a cosmetic product and associated applicator assembly
The invention relates to a cosmetic product applicator ( 10 ) with a core ( 12 ) having a first end, called proximal end ( 13 ), and a second free end, called distal end ( 16 ), and a plurality of protuberances ( 30 ) protruding from the core ( 12 ). The protuberances ( 30 ) are molded with the core ( 12 ) and are arranged in a plurality of rows extending in the extension direction (Y) of a sleeve ( 14 ) extending the core ( 12 ). The free ends of said protuberances ( 30 ) form two separate enclosures, a first of said enclosures having an outer bulk smaller than that of the second enclosure (E 2 ). The number of rows, called first rows, forming the first enclosure being smaller than the number of rows, called second rows, forming the second enclosure (E 2 ). The invention also related to an associated applicator assembly.
1. Applicator for a cosmetic product, comprising:
a core having a first end, referred to as a proximal end, and a second, free end, referred to as a distal end, and
a plurality of protrusions projecting from the core,
wherein the plurality of protrusions form a circular cross-section of the applicator;
wherein said protrusions are moulded with the core and are arranged in a plurality of rows extending in an extension direction (Y) of a cylindrical coupling which extends the core, and wherein free ends of said protrusions form two separate envelopes (E 1 , E 2 ) each envelope being spindle-shaped, a first of said envelopes (E 1 ) having an external size (dE 1 , DE 1 ) that is less than that of a second of said envelopes (E 2 ), the number of rows, referred to as first rows, forming the first envelope (E 1 ) being lower than the number of rows, referred to as second rows, forming the second envelope (E 2 ); and
wherein the core has a longitudinal extension (X) which has a first portion (X 1 ) that is curved from the proximal end to a central portion of the applicator and a second portion (X 2 ) that is curved from said central portion to the distal end.
2. Applicator according to claim 1 , wherein the curvatures of the first and the second portion (X 1 , X 2 ) of said longitudinal extension (X) are opposite.
3. Applicator according to claim 1 , wherein said first and second envelopes (E 1 , E 2 ) are homothetic with respect to one another.
4. Applicator according to claim 1 , wherein said rows are parallel to the axis of longitudinal extension (Y) of the cylindrical coupling.
5. Applicator according to claim 1 , wherein said rows are radially spaced around the periphery of the core at a constant angular distance.
6. Applicator according to claim 5 , wherein said angular distance is 30°.
7. Applicator according to claim 1 , wherein the number of second rows is two to six times greater than the number of first rows.
8. Applicator according to claim 1 , wherein the protrusions each have a planar surface, the protrusions being positioned such that planar surfaces of two adjacent protrusions are oriented in the same rotational direction.
9. Applicator assembly for a cosmetic product, comprising:
a container comprising a body which forms a reservoir intended to contain the cosmetic product, and
an applicator according to claim 1 , which can be attached to the container such that said applicator is housed within the reservoir.
10. Applicator assembly according to claim 9 , wherein said container comprises a wiper, said wiper having an internal diameter of which the value is between the maximum external size (DE 1 ) of the first envelope (E 1 ) and the maximum external size (DE 2 ) of the second envelope (E 2 ).
