Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
149 words
A comb for removing nits comprising: a handle; and means forming a plurality of elongated metal teeth comprising a plurality of discrete elongated metal tooth members, each having a mounting portion and a tine portion extending therefrom, wherein each metal tooth member is configured when disposed side by side with another metal tooth member to form an intertooth clearance between adjacent tine portions which tapers down to a minimum of about 100μ and wherein the tine portions have a substantial longitudinal extent wherein the intertooth clearance tapers from about 120μ to about 100μ, and means fixedly interconnecting the tooth members side-by-side comprising an elongated channel in each mounting portion of the tooth and an elongated interconnecting member configured to be tightly received in each elongated channel to align same side-by-side with the aforesaid clearance; and means mounting the teeth in the handle with only the tine portion projecting therefrom.
Claim 2
Dependent Claim
149 words
A comb for removing nits comprising: a handle; and means forming a plurality of elongated metal teeth comprising a plurality of discrete elongated metal tooth members, each having a mounting portion and a tine portion extending therefrom, wherein each metal tooth member is configured when disposed side by side with another metal tooth member to form an intertooth clearance between adjacent tine portions which tapers down to a minimum of about 100μ and wherein the tine portions have a substantial longitudinal extent wherein the intertooth clearance tapers from about 120μ to about 100μ, and means fixedly interconnecting the tooth members side-by-side comprising an elongated channel in each mounting portion of the tooth and an elongated interconnecting member configured to be tightly received in each elongated channel to align same side-by-side with the aforesaid clearance; and means mounting the teeth in the handle with only the tine portion projecting therefrom.
Claim 3
Independent Claim
140 words
A method of producing a comb for removing nits comprising: forming a plurality of metal teeth by providing a plurality of discrete metal tooth members, each having a mounting portion and a tine portion extending therefrom, configuring each metal tooth member when disposed side by side with another metal tooth member to form an intertooth clearance between adjacent tine portions which tapers down to a minimum of about 100μ and wherein the tine portions have a substantial longitudinal extent wherein the intertooth clearance tapers from about 120μ to about 100μ fixedly interconnecting the tooth members side-by-side by providing an elongated channel in each mounting portion of the tooth and inserting an elongated interconnecting member in each elongated channel to align same side-by-side with the aforesaid clearance and mounting the teeth in the handle with only the tine portion projecting therefrom.
Claim 4
Independent Claim
140 words
A method of producing a comb for removing nits comprising: forming a plurality of metal teeth by providing a plurality of discrete metal tooth members, each having a mounting portion and a tine portion extending therefrom, configuring each metal tooth member when disposed side by side with another metal tooth member to form an intertooth clearance between adjacent tine portions which tapers down to a minimum of about 100μ and wherein the tine portions have a substantial longitudinal extent wherein the intertooth clearance tapers from about 120μ to about 100μ fixedly interconnecting the tooth members side-by-side by providing an elongated channel in each mounting portion of the tooth and inserting an elongated interconnecting member in each elongated channel to align same side-by-side with the aforesaid clearance and mounting the teeth in the handle with only the tine portion projecting therefrom.
