Abstract
Abstract A vapor generating roller assembly includes a hollow perforated roller with a heatable inner surface surrounding a bore. A device which is removably insertable into the bore provides the liquid which is vaporized by the heated surface. The vapor is conveyed from the bore through the perforations into a tress of hair wound around the roller.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
80 words
A vapor generating hair roller assembly comprising: a hollow roller having a perforated outer surface suitable for winding a tress of hair therearound, said roller having an externally accessible bore with a surrounding heatable surface, said bore being in fluid communication with said perforations; and liquid providing means removably insertable into said bore for providing liquid at least proximate to said heatable surface so as to generate vapor therefrom, said vapor outletting through said perforation into the tress of hair.
Claim 2
Dependent Claim
80 words
A vapor generating hair roller assembly comprising: a hollow roller having a perforated outer surface suitable for winding a tress of hair therearound, said roller having an externally accessible bore with a surrounding heatable surface, said bore being in fluid communication with said perforations; and liquid providing means removably insertable into said bore for providing liquid at least proximate to said heatable surface so as to generate vapor therefrom, said vapor outletting through said perforation into the tress of hair.
Claim 3
Dependent Claim
48 words
The assembly of claim 1 wherein said bore is accessible through an opening at one end of said roller, said liquid providing means including a heat resistant member, and liquid absorbent material secured to said member, said member sealing said open end for preventing vapor from escaping therethrough.
Claim 4
Dependent Claim
23 words
The assembly of claim 2 wherein said absorbent material is capable of providing in excess of a predetermined amount of liquid for vaporization.
Claim 5
Dependent Claim
17 words
The assembly of claim 3 wherein said liquid is water and said predetermined amount is 0.3 grams.
Claim 6
Dependent Claim
23 words
The assembly of claim 1 wherein said liquid providing means includes a grasping portion to facilitate removal from and insertion into said roller.
Claim 7
Dependent Claim
29 words
The assembly of claim 1 wherein said liquid providing means includes a plurality of vanes extending radially therefrom for properly centering and snugly fitting said means within said bore.
Claim 8
Dependent Claim
28 words
The assembly of claim 5 wherein said roller is open at one end and said heatable surface is adapted for conductive heating when mounted on a heating post.
Claim 9
Dependent Claim
38 words
The assembly of claim 7 wherein said liquid providing means includes a sealing portion having first and second opposing sides, said first side overlapping and sealing said open end, said grasping portion extending perpendicularly from said second side.
Claim 10
Dependent Claim
28 words
The assembly of claim 8 wherein said liquid providing means includes an insert portion interconnected with said sealing portion, said insert having a liquid absorbent material secured thereto.
Claim 11
Dependent Claim
38 words
The assembly of claim 9 wherein said insert has a porous wire mesh attached thereto, said mesh having a portion offset from said insert to permit vapor movement therebetween, said liquid absorbent material being mounted on said mesh.
Claim 12
Dependent Claim
30 words
The assembly of claim 1 wherein said roller includes a cartridge composed at least in part of a heat conductive material, said bore extending at least partly into said cartridge.
Claim 13
Dependent Claim
36 words
The assembly of claim 8, said cartridge having inner heatable walls at least partly surrounding said bore and substantially concentric outer walls, a chamber being defined between said inner and outer walls containing a wax material.
Claim 14
Dependent Claim
54 words
The assembly of claim 9 wherein said roller includes a tubular outer member, an inner shell disposed between said cartridge and said outer member, said inner shell and outer member forming at least one vapor channel therebetween, said channel receiving vapor from liquid vaporized in said bore and for transfer therethrough to said perforations.
Claim 15
Dependent Claim
16 words
The assembly of claim 13 wherein said inner shell is an integral part of said cartridge.
