Abstract
Abstract A flat curler is designed for curling or undulating hair. The flat curler comprises a round bar having a bigger diameter at its ends than in its center part and an elastic band is connected to its one end to serve as a hair fixture means. A cylindrical sleeve is fitted to be longitudinally displaceable on the round bar from one end to the other. This sleeve has a longitudinal slot which is open-ended at the advance end of the sleeve. The longitudinal slot is substantially straight and axis parallel over at least the major part of the length of the sleeve. Further the longitudinal slot is closed over its total length by an overlapping edge portion that is directed opposite to the direction of the wound hair.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
170 words
A hair curler comprising an elongated bar having a medial portion and opposite end portions, said elongated bar medial portion being adapted to have first wound thereon first portions of strands of hair disposed remote from a persons scalp, a band having axially opposite end portions, a tubular sleeve defined by a tubular wall into which is telescopically slideably received through an open end portion thereof at least one of said elongated bar opposite end portions, a longitudinal slot in said tubular sleeve wall opening axially through said tubular sleeve wall open end portion whereby unwound second portions of said strands of hair can be slid axially into said longitudinal slot through said axial opening thereof and thereafter said second strand portion can be wound about said tubular sleeve, said band including means for cooperatively interconnecting said elongated bar and said tubular sleeve, and flexible flap means carried by said tubular sleeve for circumferentially overlapping said longitudinal slot in its entirety and for having wound thereupon said second strand portion.
Claim 2
Dependent Claim
170 words
A hair curler comprising an elongated bar having a medial portion and opposite end portions, said elongated bar medial portion being adapted to have first wound thereon first portions of strands of hair disposed remote from a persons scalp, a band having axially opposite end portions, a tubular sleeve defined by a tubular wall into which is telescopically slideably received through an open end portion thereof at least one of said elongated bar opposite end portions, a longitudinal slot in said tubular sleeve wall opening axially through said tubular sleeve wall open end portion whereby unwound second portions of said strands of hair can be slid axially into said longitudinal slot through said axial opening thereof and thereafter said second strand portion can be wound about said tubular sleeve, said band including means for cooperatively interconnecting said elongated bar and said tubular sleeve, and flexible flap means carried by said tubular sleeve for circumferentially overlapping said longitudinal slot in its entirety and for having wound thereupon said second strand portion.
Claim 3
Dependent Claim
42 words
The hair curler as defined in claim 1 wherein said flexible flap means is an integral extension of said tubular sleeve wall in overlapping relationship to an edge of said tubular sleeve wall which at least in part defines said longitudinal slot.
Claim 4
Dependent Claim
57 words
The hair curler as defined in claim 1 wherein said longitudinal slot is defined by a pair of longitudinal edges, said flexible flap means being a flap joined to said tubular sleeve in spaced relationship to said edges, and said flap having a circumferential length sufficient to span and overlap said slot including the longitudinal edges thereof.
Claim 5
Dependent Claim
46 words
The hair curler as defined in claim 1 including first and second corrugation means disposed respectively internally and externally of said respective tubular sleeve wall and said bar for slidably interengaging upon said bar being telescoped within said tubular sleeve and for preventing relative rotation therebetween.
Claim 6
Dependent Claim
42 words
The hair curler as defined in claim 1 including interengageable male and female socket means disposed respectively on and in said bar and tubular sleeve for slidably interengaging upon said bar being telescoped within said tubular sleeve and for preventing rotation therebetween.
Claim 7
Dependent Claim
46 words
The hair curler as defined in claim 2 including first and second corrugation means disposed respectively internally and externally of said respective tubular sleeve wall and said bar for slidably interengaging upon said bar being telescoped within said tubular sleeve and for preventing relative rotation therebetween.
Claim 8
Dependent Claim
42 words
The hair curler as defined in claim 3 including interengageable male and female socket means disposed respectively on and in said bar and tubular sleeve for slidably interengaging upon said bar being telescoped within said tubular sleeve and for preventing rotation therebetween.
Claim 9
Dependent Claim
36 words
The hair curler as defined in claim 1 including first sealing means for sealing said tubular wall opposite said open end portion, and second sealing means for sealing said tubular wall at said open end portion.
Claim 10
Dependent Claim
21 words
The hair curler as defined in claim 8 wherein said first sealing means is an end wall of said tubular sleeve.
Claim 11
Dependent Claim
32 words
The hair curler as defined in claim 8 wherein said second sealing means includes a cap carried by another of said elongated bar opposite end portions which closes said open end portion.
Claim 12
Dependent Claim
46 words
The hair curler as defined in claim 8 wherein said second sealing means is a disk carried by said elongated bar, and a perpheral surface of said disk is in internal contiguous relationship to an inner surface of said tubular wall adjacent said open end portion.
Claim 13
Dependent Claim
36 words
The hair curler as defined in claim 8 wherein said first sealing means includes an end wall of said tubular sleeve having an aperture therein, and said elongated bar one end portion seats in said aperture.
Claim 14
Dependent Claim
32 words
The hair curler as defined in claim 9 wherein said second sealing means includes a cap carried by another of said elongated bar opposite end portions which closes said open end portion.
Claim 15
Dependent Claim
46 words
The hair curler as defined in claim 9 wherein said second sealing means is a disk carried by said elongated bar, and a peripheral surface of said disk is in internal contiguous relationship to an inner surface of said tubular wall adjacent said open end portion.
Claim 16
Dependent Claim
46 words
The hair curler as defined in claim 10 wherein said second sealing means is a disk carried by said elongated bar, and a peripheral surface of said disk is in internal contiguous relationship to an inner surface of said tubular wall adjacent said open end portion.
