Brush Device For Applying A Tanning Formulation

Abstract

A brush device is disclosed having specific dimensions especially suited for use in applying a tanning formulation to the face and body of an individual. The dimensions are such that the time required to apply the formulation using the brush device is decreased compared to conventional brush devices while at the same time, undesirable streaking and uneven application are avoided. A handle structure of the brush device is disclosed which is configured to house the brush and protect the bristles after usage.

1 . A brush device for applying a tanning formulation to the face and body of an individual, comprising:
 an elongate cylindrical handle structure having a longitudinal axis, a first longitudinal end and a second longitudinal end, said handle structure having a length in the range of between about 4¼ inches and 5¼ inches and a diameter in the range of between about 1¼ inches and 2 inches; and   a plurality of bristles having portions extending from said second end of said handle structure forming a brush, said brush having circular cross-sections in respective planes transverse to said longitudinal axis of said handle structure, said transverse cross-section of said brush at said second end of said handle structure having a diameter in the range of between about 1¼ inches and 2 inches, and wherein a diameter of a largest transverse cross-section of said brush is in the range of between about 2¼ inches and 2¾ inches.   
     
     
         2 . A brush device as recited in  claim 1  wherein the height of the brush is in the range of between about 1⅝ inches and 2⅛ inches. 
     
     
         3 . A brush device as recited in  claim 2  wherein said brush has a frusto-conical shape from a base to said largest transverse cross-section and a spherical section shape from said largest transverse cross-section to a top of said brush. 
     
     
         4 . A brush device as recited in  claim 1  wherein the length of said handle structure is about 4¾ inches, said diameter of said handle structure is about 1½ inches, said diameter of said largest transverse cross-section is about 2½ inches and the height of said brush is about 1⅞ inches. 
     
     
         5 . A brush device as recited in  claim 1  wherein said handle structure comprises:
 an outer cylindrical case having a closed end constituting said first longitudinal end of said handle structure and an open end; 
 an inner cylindrical brush holder situated coaxially within said outer cylindrical case and fixed thereto; 
 an intermediate cylindrical case situated coaxially between said outer cylindrical-case and said inner cylindrical brush holder, said intermediate cylindrical case having an open end constituting said second longitudinal end of said handle structure; 
 said outer cylindrical case, inner cylindrical brush holder and intermediate cylindrical case configured such that said intermediate cylindrical case in slidable between a first retracted position in which said open end thereof is situated outside of said outer cylindrical case a first distance form said open end of said outer case and constitutes said second longitudinal end of said handle structure, and a second extended position in which said open end thereof is situated outside of said outer cylindrical case a second distance from said open end of said outer case which is greater than said first distance, and wherein said rush is housed within said intermediate case when said intermediate case is in said second extended position. 
 A brush device as recited in  claim 6  wherein said the length of said cylindrical cover is in the range of between about 3⅞ inches and 4⅛ inches. 
 
     
     
         6 . A brush device as recited in  claim 5  further comprising a cylindrical cover having a first closed end and a second open end, said second open end configured to be connected to said open end of said intermediate cylindrical case when said intermediate cylindrical case is in said second extended position, and wherein said rush is housed within said cylindrical cover when said intermediate cylindrical case is moved to said first retracted position. 
     
     
         7 . A brush device as recited in  claim 6  wherein said the length of said cylindrical cover is in the range of between about 3⅞ inches and 4⅛ inches.
