Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
59 words
A hair curler comprising a first coreless hollow sleeve of flexible foam plastic material closed at one end, a second sleeve surrounding said first sleeve, said second sleeve having spaced longitudinally extending aperture means around its periphery to render the central portion of the second sleeve flexible, the other end of said first sleeve being arranged to receive steam.
Claim 2
Dependent Claim
59 words
A hair curler comprising a first coreless hollow sleeve of flexible foam plastic material closed at one end, a second sleeve surrounding said first sleeve, said second sleeve having spaced longitudinally extending aperture means around its periphery to render the central portion of the second sleeve flexible, the other end of said first sleeve being arranged to receive steam.
Claim 3
Dependent Claim
25 words
A hair curler in accordance with claim 1 wherein said aperture means are having therefor oppositely disposed teeth along the opposite edges of said slots.
Claim 4
Dependent Claim
22 words
A hair curler in accordance with claim 2 wherein said teeth are arcuate and correspond to the circumference of the second sleeve.
Claim 5
Dependent Claim
35 words
A hair curler in accordance with claim 1 including a shield removably attached to the opposite ends of the second sleeve and having its inner surface spaced from the outer surface of the second sleeve.
Claim 6
Dependent Claim
23 words
A hair curler in accordance with claim 1 wherein said one end of the first sleeve is closed by a removable end cap.
Claim 7
Dependent Claim
69 words
A hair curler comprising a first sleeve of flexible foam plastic material closed at one end and open at its other end for receiving steam, said sleeve being closed at said one end by a removable core having longitudinally extending slots, a second sleeve surrounding said first sleeve, said second sleeve having longitudinally extending slots spaced around its periphery to render the central portion of the second sleeve flexible.
Claim 8
Dependent Claim
69 words
A hair curler comprising a first sleeve of flexible foam plastic material closed at one end and open at its other end for receiving steam, said sleeve being closed at said one end by a removable core having longitudinally extending slots, a second sleeve surrounding said first sleeve, said second sleeve having longitudinally extending slots spaced around its periphery to render the central portion of the second sleeve flexible.
Claim 9
Dependent Claim
42 words
A hair curler in accordance with claim 6 wherein said core has an outer diameter which is slightly greater than the inner diameter of said first sleeve so as to provide a force-fit while permitting removal of the core by finger pressure.
Claim 10
Dependent Claim
36 words
A hair curler in accordance with claim 6 including a third sleeve telescoped over said second sleeve, said third sleeve being a foam plastic material whose radial thickness is thinner than that of the first sleeve.
Claim 11
Dependent Claim
21 words
A hair curler in accordance with claim 6 wherein said slots of said second sleeve have arcuate teeth for catching hair.
Claim 12
Dependent Claim
27 words
A hair curler in accordance with claim 6 wherein the axial length of said first sleeve is slightly greater than the axial length of said second sleeve.
Claim 13
Dependent Claim
119 words
A steamable hair curler comprising: a porous foam plastic hollow sleeve surrounded by a second sleeve of more rigid material impervious to liquids, said second sleeve being substantially thinner than said first sleeve, the inner diameter of said second sleeve being slightly smaller than the outer diameter of said first sleeve so as to provide an interference fit therebetween, said second sleeve having a plurality of openings in its central portion to render the said portion flexible so that it may deform inwardly and assume a concave shape and through which steam may escape, and means closing only one end of the bore in said first mentioned sleeve, the other end of said bore being arranged to receive steam.
Claim 14
Dependent Claim
119 words
A steamable hair curler comprising: a porous foam plastic hollow sleeve surrounded by a second sleeve of more rigid material impervious to liquids, said second sleeve being substantially thinner than said first sleeve, the inner diameter of said second sleeve being slightly smaller than the outer diameter of said first sleeve so as to provide an interference fit therebetween, said second sleeve having a plurality of openings in its central portion to render the said portion flexible so that it may deform inwardly and assume a concave shape and through which steam may escape, and means closing only one end of the bore in said first mentioned sleeve, the other end of said bore being arranged to receive steam.

A hair curler in accordance with claim 11 wherein said closing means is an end cap attached to the outer periphery of said second sleeve.
Claim 20
Dependent Claim
86 words
A steamable hair curler comprising a hollow sleeve of foam plastic, a hollow core having its outer periphery of uniform diameter and telescoped into said sleeve with an interference fit, said core being made from a liquid impervious material and having a plurality of aperatures in a central portion thereof to facilitate escape of steam in a radical direction, said core being closed at one end and having an opening st its other end for receiving steam, said core and sleeve having substantially the same length.
Claim 21
Dependent Claim
86 words
A steamable hair curler comprising a hollow sleeve of foam plastic, a hollow core having its outer periphery of uniform diameter and telescoped into said sleeve with an interference fit, said core being made from a liquid impervious material and having a plurality of aperatures in a central portion thereof to facilitate escape of steam in a radical direction, said core being closed at one end and having an opening st its other end for receiving steam, said core and sleeve having substantially the same length.
Claim 22
Dependent Claim
44 words
A hair curler in accordance with claim 17 including a shield removably attached to the ends of said core by radially disposed members, said shield being spaced from the outer periphery of said sleeve so that hair to be curled may be disposed therebetween.
