Abstract

An applicator assembly (10) for applying liquid product to the hair. The applicator assembly (10) has an applicator (20) that further has a base (30) and multiple tines (50) extending from the base (30). Opposite the tines (50), the base (30) has a liquid distribution cavity. At least some of the tines (50) have a tip (64) at the end opposite the base (30), and may also have an enlarged fin (54) section adjacent to the base (30). The enlarged fin (54) section extends to a shoulder portion located less than half way upward between the base (30) and the tip (64) of the tine (50). The tines (50) may also have an aperture that allows fluid to be distributed from the cavity directly to the hair. The tip (64) of the tine (50) may be relatively flexible, while its enlarged fin (54) section provides a more rigid lower portion.

Claims (17)

1. An applicator assembly (10) for applying liquid to hair, said applicator assembly comprising an applicator (20) having a base (30) comprising a liquid distribution cavity (132), a plurality of tines (50) each having a longitudinal length (L) extending from said base, wherein at least one of said tines further comprise a tip (64) having an end located distally from said base, and an aperture (62, 68) in fluid communication with said liquid distribution cavity, characterized in that at least one of said tines further comprises an enlarged fin (54) section adjacent to said base, said fin section extending along said tine less than half way upward between said base and the distal end of said tip.
2. An applicator assembly according to claim 1, comprising at least two apertures (62, 68) spaced along said longitudinal length (L) above said fin (54).
3. An applicator assembly according to any preceding claim, wherein at least one of said tines (50) has an aperture channel (170) providing fluid communication between said aperture (62, 68) and said distribution cavity (132).
4. An applicator assembly (10) for applying liquid to hair, said applicator assembly comprising an applicator (20) having a base (30) comprising a liquid distribution cavity (132), a plurality of tines (50) each having a longitudinal length (L) extending from said base, wherein at least one of said tines further comprise a tip (64) having an end located distally from said base, and an aperture (62, 68) in fluid communication with said liquid distribution cavity, characterized in that said aperture comprises at least two spaced dispensing apertures and at least two aperture channels (170), each aperture channel providing fluid communication between one of said dispensing apertures and said distribution cavity.
5. An applicator assembly according to claim 4, wherein at least one of said tines (50) further comprises an enlarged fin (54) section adjacent to said base, preferably wherein said fin section extends along said tines less than half-way upward between said base and the distal end of said tip (64).
6. An applicator assembly according to any preceding claim, wherein at least one of said tines (50) has a longitudinal length (L) that is different from the longitudinal length at least one other of said tines.
7. An applicator assembly according to any of claims 1-3, or 5-6, wherein the distal end of said fin (54) comprises a shoulder portion (56) having a substantially horizontal component along said tine (50).

9. An applicator assembly according to any preceding claim, comprising at least two apertures (62, 68), wherein said apertures are oriented at different dispensing angles relative to the longitudinal length (L) of said tine (50).
10. An applicator assembly according to any of claims 1 to 8, comprising a pair of apertures (62, 68), wherein said apertures are oriented in substantially the same direction as the longitudinal length (L) of said tine (50).
11. An applicator assembly (10) for applying liquid to hair, said applicator assembly comprising an applicator (20) having a base (30) comprising a liquid distribution cavity (132), a plurality of tines (50) each having a longitudinal length (L) extending from said base, wherein at least one of said tines further comprise a tip (64) having an end located distally from said base, and an aperture (62, 68) in fluid communication with said liquid distribution cavity, characterized in that at least one of said tines further comprises an enlarged fin (54) section adjacent to said base, and at least one of said tines further comprising said enlarged fin section is configured to provide a substantially rigid lower section (386) and a substantially flexible upper section (384) adjacent said tip.
12. An applicator assembly according to claim 11, wherein said substantially rigid lower section (386) has a modulus from 345 megapascals (50,000 psi) to 1379 megapascals (200,000 psi), and said substantially flexible upper section (384) has a durometer hardness from 50 Shore A
