Lash brush with adjustable bristle arrangement

Abstract

The present invention relates to a lash brush that allows for adjustment of the arrangement of bristles formed on a bristle sleeve of the lash brush according to practical needs and enhances the operation of lash make-up. A bristle bar assembly includes an inner bar that is retained in an end cap by a rim member defining guide slots and an outer tube fit over and encompassing the inner bar. A front end of a bristle sleeve is coupled to an end of the outer tube and an end of the inner bar is inserted into and fixed to an inner end of the bristle sleeve. In use, through withdrawing and rotating the cap, the inner bar rotates the end of the bristle sleeve, causing twisting of a bristle tip surface formed by tips of bristles and thus realizing adjustment of the arrangement of the bristles.

1 . A lash brush comprising an end cap for hand gripping, a bristle sleeve having a bristle tip surface and a bristle carrying bar assembly, characterized in that the bar assembly comprises an inner bar and an outer tube fit to each other, wherein the inner bar is inserted into and fixed to an inner recess of the cap and is further fixed from outside thereof by a rim member that is fit into an outer end portion of the cap to be positioned on a bottom portion of the inner bar to provide assistance of positioning the inner bar, the cap forming an opening and having an inside surface on which positioning bosses are formed close to the opening for being received in positioning notches of circumferential guide slots defined in a circumferential wall of the rim member for positioning of the cap in rotation control of the cap, the outer tube being fit from outside into and fixed to an inner recess of the rim member to form a nested arrangement, an end of the outer tube being fit and coupled to an insertion end of the bristle sleeve on which the bristles are arranged, a distal end of the inner bar inserted into and fixed to an inner end of the bristle sleeve so that the two ends of the bristle sleeve are respectively fixed to ends of the inner bar and the outer tube, wherein in use, when the cap is rotated, through the rotation of the inner bar, the inner end of the bristle sleeve is also rotated so as to twist and thus adjust arrangement of the bristles to provide selection for applications in lash make-up operations. 
     
     
         2 . The lash brush according to  claim 1 , wherein the circumferential guide slots of the rim member provides guidance to the rotation of the cap for realizing control of the twisting of the bristle tip surface. 
     
     
         3 . The lash brush according to  claim 1 , wherein the circumferential guide slots of the rim member have a side forming raised and recessed arc surfaces to realize positioning for the twisting in various angular locations. 
     
     
         4 . The lash brush according to  claim 1 , wherein the circumferential guide slots of the rim member have a length allowing for rotation of the cap within an angular range between 0-150 degrees.
