Claims Analysis

Total Claims: 17
Claim 1
Independent Claim 85 words
A hair curler for use with steam comprising a hollow perforated core, said core having an opening only at one end, a purous sleeve around said core, a rim at each end of the core, the diameter of the rim being greater than the diameter of the core, at least one rim being releasably connected to the core, and a finger contact surface on the exterior surface of each rim, at least one of said finger contact surfaces being annular and coaxial with said opening.
Claim 2
Dependent Claim 85 words
A hair curler for use with steam comprising a hollow perforated core, said core having an opening only at one end, a purous sleeve around said core, a rim at each end of the core, the diameter of the rim being greater than the diameter of the core, at least one rim being releasably connected to the core, and a finger contact surface on the exterior surface of each rim, at least one of said finger contact surfaces being annular and coaxial with said opening.
Claim 3
Dependent Claim 48 words
A hair curler in accordance with claim 1 including a shield which is generally semi-circular, said shield having end walls, each end wall having a notch, said end walls being juxtaposed to an associated rim and being between the rims while the core is received in said notches.
Claim 4
Dependent Claim 29 words
A hair curler in accordance with claim 2 wherein the outer peripheral surface of the core engages the surfaces of a notch in the end wall of the shield.
Claim 5
Dependent Claim 47 words
A hair curler in accordance with claim 2 wherein each rim has an axially extending hub overlying an adjacent end portion of the sleeve, the outer periphery of each hub being in contact with a surface of the notch on the associated end wall of the shield.
Claim 6
Dependent Claim 36 words
A hair curler in accordance with claim 2 including at least one ridge on the outer peripheral surface of the shield adjacent the free ends thereof to increase friction and facilitate rapid grasping of the shield.
Claim 7
Dependent Claim 24 words
A hair curler in accordance with claim 2 including a plurality of passages in the shield to facilitate blowing hot air through said passages.
Claim 8
Dependent Claim 28 words
A hair curler in accordance with claim 1 including a second sleeve surrounding said first sleeve, said second sleeve having integral outwardly extending projections to facilitate catching hair.
Claim 9
Dependent Claim 40 words
A hair curler in accordance with claim 1 wherein each of said finger contact surfaces is an annular boss extending in opposite directions away from their associated rims and having a diameter corresponding generally to the diameter of the core.
Claim 10
Dependent Claim 104 words
A hair curler for use with steam comprising a hollow core having longitudinally extending slots, an opening at only one end of the core, a porous sleeve around said core, a rim at each end of the core, means cooperating with the outer periphery of said core to define an annular channel at each end of the core, each end of said sleeve extending into one of said annular channels, a finger contact portion on the outer surface of each rim and extending away from the adjacent end of said core, one of said finger contact portions being annular and coaxial with said opening.
Claim 11
Dependent Claim 104 words
A hair curler for use with steam comprising a hollow core having longitudinally extending slots, an opening at only one end of the core, a porous sleeve around said core, a rim at each end of the core, means cooperating with the outer periphery of said core to define an annular channel at each end of the core, each end of said sleeve extending into one of said annular channels, a finger contact portion on the outer surface of each rim and extending away from the adjacent end of said core, one of said finger contact portions being annular and coaxial with said opening.
Claim 12
Dependent Claim 142 words
A hair curler for use with steam comprising a hollow perforated core, said core having an opening only at one end, a porous foam plastic tubular pad around said core, a rim at each end of the core, the diameter of the rim being greater than the diameter of the core, a finger contact surface on the exterior surface of each rim, each of said finger contact surfaces being annular and coaxial with said opening, a shield which is generally semi-circular, said shield having end walls, each end wall having a notch, said end walls being juxtaposed to an associated rim and being between the rims while the core is received in said notches, and at least one ridge on the outer peripheral surface of the shield adjacent the free ends thereof to increase friction and facilitate rapid grasping of the shield.
Claim 13
Dependent Claim 142 words
A hair curler for use with steam comprising a hollow perforated core, said core having an opening only at one end, a porous foam plastic tubular pad around said core, a rim at each end of the core, the diameter of the rim being greater than the diameter of the core, a finger contact surface on the exterior surface of each rim, each of said finger contact surfaces being annular and coaxial with said opening, a shield which is generally semi-circular, said shield having end walls, each end wall having a notch, said end walls being juxtaposed to an associated rim and being between the rims while the core is received in said notches, and at least one ridge on the outer peripheral surface of the shield adjacent the free ends thereof to increase friction and facilitate rapid grasping of the shield.
Claim 14
Dependent Claim 29 words
A hair curler in accordance with claim 10 wherein the outer peripheral surface of the core engages the surfaces of a notch in the end wall of the shield.
Claim 15
Dependent Claim 47 words
A hair curler in accordance with claim 10 wherein each rim has an axially extending hub overlying an adjacent end portion of the pad, the outer periphery of each hub being in contact with a surface of the notch on the associated end wall of the shield.
Claim 16
Dependent Claim 24 words
A hair curler in accordance with claim 10 including a plurality of passages in the shield to facilitate blowing hot air through said passages.
Claim 17
Dependent Claim 25 words
A hair curler in accordance with claim 10 including a sleeve surrounding said pad, said sleeve having integral outwardly extending projections to facilitate catching hair.
