Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 150 words
A hair curler for use with a source of steam comprising a hollow perforated core having an opening at one end for the purpose of introducing steam thereinto, a hub at each end of the core, each hub being provided with greater transverse dimensions than the transverse dimensions of the core, a porous pad around the perforated core, an impervious steam shield for protecting the scalp of a wearer, the circumference of said shield being less than 360 degrees, said core being juxtaposed to said shield with sufficient clearance so that hair can be wound around the pad and be disposed between the pad and the inner surface of the shield, and means for removably coupling the shield to one of said hubs, whereby steam may be introduced into said core by way of said opening and discharged radially therefrom through perforations in the core and through said porous pad.
Claim 2
Dependent Claim 150 words
A hair curler for use with a source of steam comprising a hollow perforated core having an opening at one end for the purpose of introducing steam thereinto, a hub at each end of the core, each hub being provided with greater transverse dimensions than the transverse dimensions of the core, a porous pad around the perforated core, an impervious steam shield for protecting the scalp of a wearer, the circumference of said shield being less than 360 degrees, said core being juxtaposed to said shield with sufficient clearance so that hair can be wound around the pad and be disposed between the pad and the inner surface of the shield, and means for removably coupling the shield to one of said hubs, whereby steam may be introduced into said core by way of said opening and discharged radially therefrom through perforations in the core and through said porous pad.
Claim 3
Dependent Claim 27 words
A hair curler in accordance with claim 1 wherein said coupling means includes a discrete clip, said clip extending generally parallel to the axis of said core.
Claim 4
Dependent Claim 40 words
A hair curler in accordance with claim 1 wherein said shield includes spaced inner and outer walls connected together adjacent their free edges, the space between said walls being open directly to the atmosphere at the ends of said space.
Claim 5
Dependent Claim 26 words
A hair curler in accordance with claim 1 wherein said porous pad is a foam polymeric plastic pad, and said shield being disposed between said hubs.
Claim 6
Dependent Claim 159 words
A hair curler for use with a source of steam comprising a hollow perforated core having a steam inlet opening at one end, a steam impervious shield for protecting the scalp of a wearer, said shield being hollow and generally semi-circular in cross-section, said hollow shield having spaced inner and outer generally semi-circular walls connected together adjacent their free edges, the space between said walls being open directly to the atmosphere by way of at least one open end of said space, said core being juxtaposed to the surface of the inner wall of said shield with sufficient clearance so that hair can be wound around the core and be disposed between the core and the inner wall of said shield, and means for remoVably coupling the shield to said core, whereby steam may be introduced into said core by way of the inlet opening and discharged radially from the core by way of said perforations in the core.
Claim 7
Dependent Claim 159 words
A hair curler for use with a source of steam comprising a hollow perforated core having a steam inlet opening at one end, a steam impervious shield for protecting the scalp of a wearer, said shield being hollow and generally semi-circular in cross-section, said hollow shield having spaced inner and outer generally semi-circular walls connected together adjacent their free edges, the space between said walls being open directly to the atmosphere by way of at least one open end of said space, said core being juxtaposed to the surface of the inner wall of said shield with sufficient clearance so that hair can be wound around the core and be disposed between the core and the inner wall of said shield, and means for remoVably coupling the shield to said core, whereby steam may be introduced into said core by way of the inlet opening and discharged radially from the core by way of said perforations in the core.
Claim 8
Dependent Claim 35 words
A hair curler in accordance with claim 5 including a foam polymeric plastic pad which is porous to steam, said pad surrounding said perforated core and being spaced from said inner wall of the shield.
Claim 9
Dependent Claim 57 words
A hair curler in accordance with claim 5 including a hub at each end of the core, each hub having a greater transverse dimension than the dimensions of the core, each hub engaging the inner surface of the inner wall of said shield, and said coupling means interconnecting said shield with at least one of said hubs.
Claim 10
Dependent Claim 42 words
A hair curler in accordance with claim 5 including a hub at each end of the core, each hub having a radially outwardly directed rim, the radius of each rim corresponding generally to the radius of the outer wall of the shield.
Claim 11
Dependent Claim 33 words
A hair curler in accordance with claim 8 wherein at least one of said rims has an opening aligned with an opening in the shield, said coupling means extending through said aligned openings.
