Applicator Assembly for Applying a Composition

Abstract

A method for delivering a composition to the scalp including (a) providing a composition in an applicator assembly, the applicator assembly including (i) a container for holding the composition; (ii) an extended tip actuator in fluid communication with the container, the extended tip actuator including (1) a base portion configured to fluidly connect the extended tip actuator to the container; and (2) a body portion configured to fluidly connect the base portion to a hollow tine; and (iii) an engine for delivering the composition from the container through the extended tip actuator; and (b) dispensing the composition from the applicator assembly directly onto the scalp. The tine includes a face located distally from the body portion. The tine includes an aperture in fluid communication with the container. The tine has a protrusion length of from about 0.5 mm to about 100 mm.

What is claimed is: 
     
         1 ) A method for delivering a composition to the scalp comprising:
 a. providing a composition in an applicator assembly, the applicator assembly comprising:
 i. a container for holding the composition; 
 ii. an extended tip actuator in fluid communication with the container, the extended tip actuator comprising:
 1. a base portion configured to fluidly connect the extended tip actuator to the container; and 
 2. a body portion configured to fluidly connect the base portion to a hollow tine, wherein the tine comprises a face located distally from the body portion, wherein the tine comprises an aperture in fluid communication with the container, and wherein the tine has a protrusion length of from about 0.5 mm to about 100 mm; and 
 
 iii. an engine for delivering the composition from the container through the extended tip actuator; and 
   b. dispensing the composition from the applicator assembly directly onto the scalp.   
     
     
         2 ) The method of  claim 1 , wherein the tine has a protrusion length of from about 10 mm to about 60 mm. 
     
     
         3 ) The method of  claim 1 , wherein the tine has a protrusion length of from about 20 mm to about 50 mm. 
     
     
         4 ) The method of  claim 1 , wherein the aperture has a diameter of from about 0.2 mm to about 2 mm. 
     
     
         5 ) The method of  claim 4 , wherein the aperture has a diameter of from about 0.5 mm to about 1.5 mm. 
     
     
         6 ) The method of  claim 1 , wherein the engine is a pump. 
     
     
         7 ) The method of  claim 1 , wherein the engine dispenses from about 0.05 mL to about 4 mL per complete stroke. 
     
     
         8 ) The method of  claim 7 , wherein the engine dispenses from about 0.1 mL to about 1 mL per complete stroke. 
     
     
         9 ) The method of  claim 7 , wherein the engine dispenses from about 0.3 mL to about 0.5 mL per complete stroke. 
     
     
         10 ) The method of  claim 1 , wherein the applicator assembly further comprises a longitudinal axis therethrough, and the tine is angled from about 20° to about 100° from the longitudinal axis. 
     
     
         11 ) The method of  claim 1 , wherein the applicator assembly further comprises a longitudinal axis therethrough, and the tine is angled from about 30° to about 60° from the longitudinal axis. 
     
     
         12 ) The method of  claim 1 , wherein the applicator assembly further comprises a longitudinal axis therethrough, and wherein the face is angled from about 35° to about 55° from the longitudinal axis. 
     
     
         13 ) The method of  claim 1 , wherein the composition comprises from about 0.1% to about 25% niacinamide. 
     
     
         14 ) The method of  claim 1 , wherein the composition comprises from about 10% to about 90% alcohol. 
     
     
         15 ) The method of  claim 1 , wherein the applicator assembly further comprises a composition comprising an anti-dandruff agent. 
     
     
         16 ) An applicator assembly for delivering a composition to the scalp comprising:
 a. a container for holding the composition;   b. an extended tip actuator in fluid communication with the container, the extended tip actuator comprising:
 i. a base portion configured to fluidly connect the extended tip actuator to the container; and 
 ii. a body portion configured to fluidly connect the base portion to a hollow tine, wherein the tine comprises a face located distally from the body portion, wherein the tine comprises an aperture in fluid communication with the container, and wherein the tine has a protrusion length of from about 0.5 mm to about 100 mm; and 
   c. an engine for delivering the composition from the container through the extended tip actuator to the scalp.   
     
     
         17 ) The applicator assembly of  claim 16 , wherein the applicator assembly further comprises a longitudinal axis therethrough, and the tine is angled from about 20° to about 100° from the longitudinal axis. 
     
     
         18 ) The applicator assembly of  claim 16 , wherein the applicator assembly further comprises a longitudinal axis therethrough, and the tine is angled from about 25° to about 70° from the longitudinal axis. 
     
     
         19 ) The applicator assembly of  claim 16 , wherein the applicator assembly further comprises a longitudinal axis therethrough, and the tine is angled from about 35° to about 55° from the longitudinal axis. 
     
     
         20 ) The applicator assembly of  claim 16 , wherein the composition comprises from about 0.1% to about 25% niacinamide.
