Applicator head for applying a cosmetic product

An applicator head for applying a cosmetic or a care product, the applicator head comprises:

• an applying member elongated along a longitudinal axis;
• a shank member at a proximal end of the applying member;
• wherein the applying member includes a distal end face and at least one sidewall extending from the proximal end of the applying member to a peripheral edge of the distal end face;
• wherein the distal end face of the applying member is an inclined and convex surface;
• wherein the at least one sidewall of the applying member includes a proximal portion adjacent to the shank member, a distal portion, and a concave central portion extending between the distal portion and the proximal portion;
• wherein the proximal portion is configured to be spherical or cylindrical;
• wherein the distal portion has a flared oval shape;
• wherein the proximal portion has transverse cross-sections that are circular;
• wherein the distal portion and the concave central portion have rounded transverse cross-sections that are oval or elliptical;
• wherein each of the transverse cross-sections at the distal portion and the concave central portion has a major axis and a minor axis,
• wherein the length of the major axes of the transverse cross-sections increases gradually from a mid-length of the applying member towards the distal end face of the applying member;
• wherein the at least one sidewall includes a front side face, a back side face, a left side face, and a right side face;
• wherein the left side face and the right side face are symmetrical relative to a mid-plane comprising the longitudinal axis of the applying member;
• wherein a width of the distal portion at each of the left side face and the right side face is 30% more than a corresponding width of the distal portion at each of the front side face and the back side face;
• wherein a minimum width of each of the front side face, the back side face, the left side face, and the right side face is defined at the concave central portion;
• wherein the minimum width of each of the front side face and the back side face is at least 20% less than the minimum width of each of the left side face and the right side face;
• wherein the distal end face has an ellipse shape;
• wherein a surface area of the distal end face is at least 10% smaller than a surface area of the front side face;
• and
• wherein a surface area of the distal end face at least 20% smaller than the surface area of each of the backside face, the left side face, and the right side face.

• wherein the front side face has a height less than the height of the back side face;
• and wherein
• the height of the front side face is at least 60% of the height of the back side face.
