Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 177 words
A generally flat plastic member adapted to be formed into a hair curler comprising: an elongated rectangular portion having a plurality of openings therein arranged in a plurality of rows substantially parallel to the sides of said rectangular portion; a locking member adjacent to one end of said rectangular portion and integral therewith, said locking member being substantially wider than said rectangular portion and having a region extending substantially perpendicular to said sides of said rectangular portion and a forward member substantially parallel to and spaced apart from said region so as to define a slot for receiving said rectangular section therethrough in an inward curving direction when said generally flat plastic member is rolled into a hair curler, said forward member having a plurality of engaging members, each disposed in alignment with one of said plurality of rows of openings in said rectangular portion and projecting generally perpendicular to said flat sheet so as to be outwardly engageable with a plurality of said openings to retain said flat sheet in a coil forming said hair curler.
Claim 2
Dependent Claim 177 words
A generally flat plastic member adapted to be formed into a hair curler comprising: an elongated rectangular portion having a plurality of openings therein arranged in a plurality of rows substantially parallel to the sides of said rectangular portion; a locking member adjacent to one end of said rectangular portion and integral therewith, said locking member being substantially wider than said rectangular portion and having a region extending substantially perpendicular to said sides of said rectangular portion and a forward member substantially parallel to and spaced apart from said region so as to define a slot for receiving said rectangular section therethrough in an inward curving direction when said generally flat plastic member is rolled into a hair curler, said forward member having a plurality of engaging members, each disposed in alignment with one of said plurality of rows of openings in said rectangular portion and projecting generally perpendicular to said flat sheet so as to be outwardly engageable with a plurality of said openings to retain said flat sheet in a coil forming said hair curler.
Claim 3
Dependent Claim 37 words
The plastic member of claim 1 wherein said locking member is substantially thicker than said rectangular portion and is separated therefrom by a flexible region having a thickness substantially less then the thickness of said rectangular portion.
Claim 4
Dependent Claim 41 words
The plastic member of claim 2 wherein said engaging members are rectangular members of substantially uniform cross-section and said plurality of openings in said rectangular portion is a plurality of rectangular openings, each at least as large as said rectangular members.
Claim 5
Dependent Claim 39 words
The plastic member of claim 3 wherein said rectangular portion has a plurality of small hair engaging protrusions therein, said protrusions projecting substantially perpendicular to said flat sheet and in the same direction as said plurality of engaging members.
Claim 6
Dependent Claim 15 words
The plastic member of claim 1 wherein said plastic member is a molded polypropylene member.
Claim 7
Dependent Claim 192 words
A plastic hair curler comprising: a first section rolled into a roll with at least the ends of said first section overlapping each other, said first section having a plurality of openings therein arranged in a plurality of rows about the circumference of the said roll; a locking member adjacent the outwardly disposed overlapping end of said first section and integral therewith, said locking member being substantially wider than said first section and having a region extending substantially parallel to the axis of said roll and adjacent the outer surface thereof, and a forward member substantially parallel to and spaced apart from said region and located within said roll adjacent the inner surface of said first section, thereby defining a slot receiving said rectangular section therethrough; and outward projecting engaging members on said forward member, said engaging members each disposed in axial alignment with one of said plurality of rows of openings in said first section, said engaging members being encouraged into engagement with an axial row of said plurality of rows of openings in said first sectioN by the elasticity of the material to lock said roll at a particular diameter.
Claim 8
Dependent Claim 192 words
A plastic hair curler comprising: a first section rolled into a roll with at least the ends of said first section overlapping each other, said first section having a plurality of openings therein arranged in a plurality of rows about the circumference of the said roll; a locking member adjacent the outwardly disposed overlapping end of said first section and integral therewith, said locking member being substantially wider than said first section and having a region extending substantially parallel to the axis of said roll and adjacent the outer surface thereof, and a forward member substantially parallel to and spaced apart from said region and located within said roll adjacent the inner surface of said first section, thereby defining a slot receiving said rectangular section therethrough; and outward projecting engaging members on said forward member, said engaging members each disposed in axial alignment with one of said plurality of rows of openings in said first section, said engaging members being encouraged into engagement with an axial row of said plurality of rows of openings in said first sectioN by the elasticity of the material to lock said roll at a particular diameter.
Claim 9
Dependent Claim 37 words
The hair curler of claim 6 wherein said locking member is substantially thicker than said first section and is separated therefrom by a flexible region having a thickness substantially less than the thickness of said rectangular portion.
Claim 10
Dependent Claim 41 words
The hair curler of claim 6 wherein said engaging members are rectangular members of substantially uniform cross-section and said plurality of openings on said first section is a plurality of rectangular openings, each at least as large as said rectangular members.
Claim 11
Dependent Claim 31 words
The hair curler of claim 8 wherein said first section has a plurality of small hair engaging protrusions therein, said protrusions projecting outward substantially perpendicular to the surface of said roll.
Claim 12
Dependent Claim 15 words
The hair curler of claim 6 wherein said plastic member is a molded polypropylene member.
