Applicator device

Abstract

An applicator device is usable for massaging and applying a cosmetic onto a human body. The applicator device includes an applicator head that is made from one of ceramic and metal material. The applicator head includes a first end, a second end opposite to the first end, a contoured surface and a groove unit disposed on the contoured surface for retaining the cosmetic therein. The contoured surface has a rounded first surface portion that is formed at the first end, and a rounded second surface portion that connects the first surface portion and that extends to the second end. The first stir face portion has a curvature larger than that of the second surface portion.

What is claimed is: 
     
         1 . An applicator device usable for massaging and applying a cosmetic onto a human body, said applicator device comprising:
 an applicator head that is made from one of ceramic and metal material, and that includes
 a first end, 
 a second end opposite to said first end, 
 a contoured surface having a rounded first surface portion that is formed at said first end, and a rounded second surface portion that connects said first surface portion and that extends to said second end, said first surface portion having a curvature larger than that of said second surface portion, and 
 a groove unit disposed on said contoured surface for retaining the cosmetic therein. 
   
     
     
         2 . The applicator device as claimed in  claim 1 , wherein said first surface portion has a largest width that is larger than a largest width of said second surface portion, said second surface portion gradually decreasing in width from said first surface portion to said second end. 
     
     
         3 . The applicator device as claimed in  claim 2 , wherein said first surface portion is convex, and said second surface portion is concave. 
     
     
         4 . The applicator device as claimed in  claim 3 , wherein said groove unit includes a plurality of grooves that extend from said first surface portion to said second surface portion. 
     
     
         5 . The applicator as claimed in  claim 4 , wherein each of said grooves has a width that gradually decreases from said first surface portion toward said second surface portion. 
     
     
         6 . The applicator as claimed in  claim 5 , wherein said grooves have a largest width ranging from. 0.5 mm to 1 mm, each of said grooves having a depth ranging from 0.3 mm to 0.5 mm. 
     
     
         7 . The applicator as claimed in  claim 6 , wherein a distance between adjacent ones of said grooves decreases from said first surface portion toward said second surface portion. 
     
     
         8 . The applicator as claimed in  claim 1 , further comprising a back surface that is connected to said first and second surface portions and that has
 a convex surface portion that is proximal to said first surface portion and that is convexed in a direction away from said first surface portion, and   a flat surface portion connecting said convex surface portion and being distal from said first surface portion.   
     
     
         9 . The applicator as claimed in  claim 8 , wherein said flat surface portion of said back surface is inclined inward and toward an axis of said applicator head. 
     
     
         10 . The applicator as claimed in  claim 1 , farther comprising a handle connected to said second end of said applicator head. 
     
     
         11 . The applicator as claimed in  claim 7 , wherein said applicator head is made from a metallic material that is selected from the group consisting of zinc, aluminum, copper, magnesium, iron, lead, cobalt, tin, and alloys thereof. 
     
     
         12 . The applicator as claimed in  claim 7 , wherein said applicator head is made from a ceramic material that includes a plurality of far infrared particles. 
     
     
         13 . An applicator device usable for massaging and applying a cosmetic to a human body, said applicator device comprising:
 an applicator head made from one of ceramic and metal material, and including:
 a first end; 
 a second end opposite to said first end; 
 a contoured surface that has a convex first surface portion formed at said first end, and a concave second surface portion that extends from a periphery of said convex first surface portion to said second end; 
 a back surface that extends from said periphery of said convex first surface portion to said second end and that has two opposite sides respectively connected to two opposite sides of said concave second surface portion; and 
 a groove unit disposed on said contoured surface for retaining the cosmetic therein. 
   
     
     
         14 . The applicator as claimed in  claim 13 , wherein said convex first surface portion has a part that has a largest width, said concave second surface portion and said back surface decreasing in width from said part of said convex first surface portion to said second end, said concave second surface portion being concaved gradually from said convex first surface portion and said second end toward an axis of said applicator head. 
     
     
         15 . The applicator as claimed in  claim 13 , wherein said back surface has a convex surface portion that is proximal to said convex first surface portion and that is convexed in a direction away from said first surface portion, and a flat surface portion connecting said convex surface portion and being distal from said first surface portion.
