Hair care device
View Patent ↗The invention provides a hair care device for use in untangling hair. The hair care device includes a body portion ( 10 a , 10 b ) and a plurality of substantially parallel flexible bristles ( 12 a , 12 b ) made of soft plastics material and projecting from the body portion. The bristles are arranged such that over at least a part of the area of bristles, some of the bristles are of shorter length ( 12 b ). The bristles and the shorter length bristles are interspersed over the at least part of the area of bristles.
1. A hair care device for use in untangling hair comprising a body portion and projecting therefrom a plurality of substantially parallel flexible bristles made of a non-rigid plastics material, the entire plurality of bristles including bristles of two different lengths, shorter length bristles and longer length bristles wherein each of the shorter length bristles is shorter than each of the longer length bristles by a uniform amount of approximately 0.007 meters;
wherein the longer length bristles and the shorter length bristles are arranged in alternating lines of longer length bristles and shorter length bristles, the lines of longer length bristles and shorter length bristles being offset relative to those in adjacent lines to centrally dispose each shorter length bristle between longer length bristles except at a periphery of the body portion:
wherein said longer length bristles are tapered or have two or more distinct sections of differing thickness, each of the longer length bristles thicker at a base section nearer to the body portion than at a free end and wherein length of the shorter length bristles approximately corresponds to a length of a longer length bristle from the base to a point of bend in the longer length bristle; and
wherein the hair care device has only the shorter length bristles and the longer length bristles and is free from any other type of bristle.
2. The hair care device as set forth in claim 1 , wherein the longer length bristles and shorter length bristles are approximately 0.014 and 0.007 meters long, respectively.
3. The hair care device as set forth in claim 1 , wherein the free ends of the longer length bristles define a first surface, the first surface curved to conform to a shape of a human head.
4. The hair care device as set forth in claim 3 , wherein the first surface is concave.
5. The hair care device as set forth in claim 3 , wherein free ends of the shorter length bristles define a second surface spaced from the first surface by a uniform distance.
6. The hair care device as set forth in claim 1 , wherein the body portion is shaped, in an area in which the plurality of bristles resides, to be curved.
7. The hair care device as set forth in claim 1 , wherein the body portion is concave to correspond with a shape of a first surface defined by the free ends of said longer length bristles.
8. The hair care device as set forth in claim 1 , wherein thinner sections of the longer length bristles commence at a distance from the body portion such that the longer length bristles have a tendency to flex in use at a point approximately at a region of free ends of the shorter length bristles.
9. The hair care device as set forth in claim 1 , wherein each of the longer length bristles and each of the shorter length bristles has a chamfer at its base.
