Abstract
A metal-toothed comb is provided having elongated identical teeth each with a square cross-section along substantially the entire length, elongated edges of each tooth being slightly rounded, free ends of each of the teeth being slightly rounded, whereby the teeth are successively positioned juxtaposed in a common plane, with elongated edges of each tooth opposing one another, and the distance between the teeth being a constant 0.004 inch along the entire length of the gap therebetween, except for a relatively small portion proximate the distal ends of each tooth, which are tapered down to a rounded tip.

A lice and nit removal comb comprising:
- a body having a first portion for hand-gripping, and a second portion adapted for rigidly retaining teeth;
- a plurality of elongated metal teeth each having a proximal end portion configured for enhancing the rigid retention thereof in said second portion of said body, each having a square cross section between proximal and distal end portions forming four longitudinal side edges, each having an equal total length ranging from 1.5 inches to 2.72 inches, the length of said teeth protruding from said second portion of said body ranging from 1.25 inches to 1.50 inches, the distal end portion of each of said teeth having a taper ranging from 1:5 to 1:8, the free ends of each of said teeth being rounded, said teeth being juxtaposed to one another with opposing side edges in parallel, and the side edges of said teeth having a space therebetween ranging from 0.0035 inch to 0.0045 inch in the distance between proximal and distal end portions, respectively.
A lice and nit removal comb comprising:
- a body having a first portion for hand-gripping, and a second portion adapted for rigidly retaining teeth;
- a plurality of elongated metal teeth each having a square cross section between proximal and distal end portions, said teeth being juxtaposed with longitudinal edge portions opposing one another, the distance between the opposing longitudinal edge portions being constant between respective proximal end distal end portions, the distance being small enough to effectively have the edge portions of said teeth scrape off and retain lice and nits from hair passed through said teeth, both the edge portions of said teeth and the free ends thereof being rounded, and extreme distal end portions of said teeth being tapered.
