Applicator head for applying a cosmetic product

An applicator head for applying a product including a cosmetic, care, or pharmaceutical product onto the keratinous substrate. The applicator head includes an applying member elongated along a central longitudinal axis. The applying member includes a front face, a rear face opposing the front face, a left face, and a right face opposing the left face. The applying member has an axial zigzag groove extending along a length of the applying member on at least one of the front face and the rear face of the applying member. The axial zigzag groove has vertices on both side of the central longitudinal axis of the applying member. Further, the applying member includes side grooves disposed on each side of the axial zigzag groove. The axial zigzag groove and the side grooves outline beads on an outer surface of the applying member.

Claims preview

1 . An applicator head for applying a cosmetic or a care product, the applicator head comprises: an applying member elongated along a central longitudinal axis; a shank member at a proximal end of the applying member; wherein the applying member includes a front face, a rear face opposing the front face, a left face, and a right face opposing the left face; wherein an axial zigzag groove extends along the applying member on each of the front face and the rear face of the applying member; wherein the axial zigzag groove is located at a middle position of each of the front face and the rear face; wherein the axial zigzag groove has vertices on both sides of the central longitudinal axis of the applying member on each of the front face and the rear face; wherein there are side grooves on an outer surface of the applying member, the side grooves are disposed on each side of the axial zigzag groove; wherein the axial zigzag grooves and the side grooves are formed on the outer surface of the applying member: wherein each of the side grooves extends laterally from one of the vertices of the axial zigzag groove of the front face to the corresponding vertices of the axial zigzag groove on the rear face of the applying member and vice-versa; wherein the side grooves interconnect the axial zigzag grooves forming channels that extend from the front face to the rear face of the applying member; and wherein the side grooves and the axial zigzag grooves outline multiple beads on the outer surface of the applying member; wherein the multiple beads are defined by the side grooves and the axial zigzag grooves; wherein the multiple beads have convex outer surfaces; wherein, when the applying member is viewed from the front face, the multiple beads comprise three left-side beads located generally on a left side of the central longitudinal axis and three right-side beads located generally on a right side of the central longitudinal axis; wherein each of the three left-side beads extends on the front face, the left face, and the rear face, and each of the three right-side beads extends on the front face, the right face, and the rear face; wherein, when seen from the front face of the applying member and proceeding from a proximal end toward a distal end of the applying member, the three left side beads incline upward toward the central longitudinal axis of the applying member, and the three right side beads incline upward toward the central longitudinal axis of the applying member; wherein each of the three left-side beads extend partially across the central longitudinal axis on the front face as well as on the rear face, and similarly each of the three right-side beads extend partially across the central longitudinal axis on the front face as well as on the rear face; wherein the left side and right side beads are arranged in alternate fashion to define alternating beads that traverse the central longitudinal axis twice, once on the front face and once on the rear face; and wherein the axial zigzag grooves and the side grooves outline on the outer surface of the applying member, an axial row of the three left side beads and an axial row of the three right side beads. 2 . The applicator head according to claim 1 , wherein the side grooves are inclined with respect to the central longitudinal axis of the applying member; and wherein the side grooves on either side of the central longitudinal axis are inclined in opposite directions. 3 . The applicator head according to claim 1 , wherein the left face of the applying member is defined by portions of the outer surfaces of the three left side beads; and wherein the right face of the applying member is defined by portions of the outer surfaces of the three right side beads.
