Brush with an internal compartment

Abstract

A brush including a handle and a head attached to the handle. The head has an upper surface and at least one protuberance positioned on the upper surface of the head. A plurality of bristle elements extend from the upper surface of the head and are positioned around the protuberance such that bristle elements positioned closest to the protuberance define a cup-shaped clearance space around the protuberance.

       2 . The brush device according to  claim 1 , wherein the at least one protuberance comprises a top surface, the top surface having a convex shape. 
   
   
       3 . The brush device according to  claim 1 , wherein the at least one protuberance comprises an outer perimeter. 
   
   
       4 . The brush device according to  claim 3 , wherein the outer perimeter has an oval shape. 
   
   
       5 . The brush device according to  claim 3 , wherein the outer perimeter has an annular shape. 
   
   
       6 . The brush device according to  claim 3 , wherein the outer perimeter has a rectangular shape. 
   
   
       7 . The brush device according to  claim 1 , wherein at least some of the plurality of bristle elements extend at an inclination angle to the upper surface of the head. 
   
   
       8 . The brush device according to  claim 1 , wherein at least some of the plurality of bristle elements extend substantially perpendicular to the upper surface of the head. 
   
   
       9 . The brush device according to  claim 1 , wherein said plurality of bristle elements have varying heights. 
   
   
       10 . The brush device according to  claim 9 , wherein a surface formed by top portions of the plurality of bristle elements has a generally concave configuration. 
   
   
       11 . The brush device according to  claim 1 , wherein the bristle elements defining the cup-shaped clearance space have a higher density than other bristle elements on the upper surface of the head. 
   
   
       12 . A brush device comprising:
 a handle having a hollow inner cavity;   a head attached to the handle, the head including an upper surface and at least one protuberance positioned on the upper surface of the head, a vertical channel being formed within the protuberance;   at least one inner channel formed within the handle and the head connecting the hollow inner cavity to the vertical channel; and   a plurality of bristle elements extending from the upper surface and being positioned around the protuberance such that bristle elements positioned closest to the protuberance define a cup-shaped clearance space around the protuberance.   
   
   
       13 . The brush device according to  claim 12 , further comprising a series of inner channels connecting the hollow inner cavity to the vertical channel. 
   
   
       14 . The brush device according to  claim 13 , wherein the series of inner channels further comprises at least one horizontal inner channel positioned in a lower portion of the head and connected to the vertical channel; and at least one elbow-shaped channel connecting the hollow space to the horizontal inner channel. 
   
   
       15 . The brush device according to  claim 12  wherein the at least one inner channel is a horizontal inner channel and wherein an accumulation space is formed below an intersection of the vertical channel and the horizontal inner channel. 
   
   
       16 . The brush device according to  claim 15 , wherein the accumulation space further comprises an outside opening covered entirely with a deformable push button. 
   
   
       17 . The brush device according to  claim 12 , wherein the at least one protuberance comprises a top surface, the top surface having a convex shape. 
   
   
       18 . The brush device according to  claim 12 , wherein the at least one protuberance comprises an outer perimeter. 
   
   
       19 . The brush device according to  claim 18 , wherein the outer perimeter has an oval shape. 
   
   
       20 . The brush device according to  claim 18 , wherein the outer perimeter has an annular shape. 
   
   
       21 . The brush device according to  claim 18 , wherein the outer perimeter has a rectangular shape. 
   
   
       22 . The brush device according to  claim 12 , wherein said plurality of bristle elements have varying heights. 
   
   
       23 . The brush device according to  claim 22 , wherein a surface formed by top portions of the plurality of bristle elements has a generally concave configuration. 
   
   
       24 . The brush device according to  claim 12 , wherein the series of inner channels further comprises at least one horizontal channel positioned in a lower portion of the head and being connected to the vertical channel; and at least one elbow-shaped channel connecting the hollow space to the horizontal channel.
