Abstract

A hair dyeing tool comprising a tray ( 3 ) with a curved bottom wall ( 12 ) contiguous with the side walls ( 13 ) of said tray; the surface of the bottom wall ( 12 ) is designed to cause the bristles in groups of bristle tufts ( 5 ) and ( 7 ) to be oriented against each other when the brush ( 4 ) is pushed against the tray ( 3 ); the orientation of the bristles in the groups of bristle tufts ( 5 ) and ( 7 ) creates a tunnel-like space (E) through which the hair strands (C) are pushed during dyeing. The curvature of the surface of the bottom wall ( 12 ) is designed to connect in an arc the center line.

Claims

exact text as granted — not AI-modified
1 . “HAIR DYEING TOOL”, which is indicated by reference number  1 , and comprises a flexible structure resembling tweezers ( 2 ), with a part that is similar to a small tray ( 3 ) on one of its ends, and on its other end a part that is similar to a brush ( 4 ) with groups of bristle tufts ( 5 ), ( 6 ), and ( 7 ) on its lower face; the groups of bristle tufts ( 5 ), ( 6 ), and ( 7 ) are developed such that the group of bristle tufts ( 5 ) has bristles of a given length which is longer than the length of two other groups of bristle tufts ( 6 ) and ( 7 ), whereas said group of bristle tufts ( 6 ), in turn, has shorter bristle length compared to the group of bristle tuft ( 7 ); the tray ( 3 ) has a raised, angled lateral end ( 8 ) and an opposing end ( 9 ) which follows the general surface level of the tray ( 3 );
 the lateral end ( 8 ) of the tray ( 2 ) [sic] has a U-shaped opening ( 10 ), whereas another U-shaped opening ( 11 ) is provided on the opposite end ( 9 ); the tool  1  is characterized in that the bottom wall ( 12 ) of the tray ( 3 ) is curved and is continuous with its lateral walls ( 13 ); the surface of the bottom wall ( 12 ) of the tray ( 3 ) is implemented so as to serve as the center point for the bristles included in the groups of bristle tufts ( 5 ) and ( 7 ) to go in opposite directions against one another when the brush ( 4 ) is pressed against the tray ( 3 ); the orientation given to the bristles of the groups of bristle tufts ( 5 ) and ( 7 ) creates a space (E) that is similar to a tunnel through which the hair strands (C) are forced during the dyeing process; the curvature of the surface of the bottom wall ( 12 ) is defined so as to link the center line of said wall ( 12 ) referenced as ( 12   a ) to the ends of the side walls ( 13 ), thus creating a sliding surface for the bristles of the two groups of bristle tufts ( 5 ) and ( 7 ); 
 the tray ( 3 ) may provide a variant wherein the structure provided in the angled, raised lateral end ( 8 ) is also provided on its opposite end ( 9 ).
