Abstract
A laminated exothermic hair curler is described having a first sheet formed of a liquid impervious material which includes a plurality of apertures and a second non-perforated sheet of liquid impervious material which is sealed in assembly with said first sheet and provides an enclosure into which an activating fluid can enter through apertues in the first sheet. A liquid absorbent sheet is positioned within the enclosure adjacent the first sheet and chemically reactive means for generating an exothermic reaction are positioned between the absorbent sheet and the second laminate sheet. This laminate assembly is formed into an elongated curler body having an arc-shaped cross sectional configuration.

A laminated hair curler assembly comprising:
- a. first sheet formed of a liquid impervious material and having a plurality of apertures formed in a thickness thereof;
- b. a second non-perforated sheet formed of a liquid impervious material and sealed with said first sheet to provide an enclosure therebetween into which a reaction activating liquid can flow through said apertures;
- c. a sheet of liquid absorbent material positioned between said first and second sheets;
- d. means positioned between said absorbent sheet and said second sheet for creating an exothermic reaction when activated by a fluid in said enclosure;
- e. means provided on said absorbent sheet for venting said exothermic reaction through said apertures;
- and
- f. said assembly formed into an elongated body having an arc-shaped cross-sectional configuration.
A laminated curler assembly comprising:
- a. a first sheet formed of a liquid impervious material and having an array of apertures formed in a thickness thereof and extending between first and second surfaces of said sheet;
- b. a sheet of liquid absorbent material having first and second surfaces thereof, said first surface of said absorbent sheet positioned adjacent said second surface of said first sheet and secured thereto along peripheral edges of said sheets;
- c. said absorbent sheet having hydrophobic areas positioned thereon which correspond in location with said apertures in said first sheet;
- d. an oxidizing granular material positioned adjacent said second surface of said absorbent sheet at surface locations on said absorbent sheet displaced in location from apertures of said first sheet;
- e. a sheet of reactive material positioned adjacent said oxidizing granular material;
- f. a second sheet of liquid impervious material extending coextensively in surface area with said first sheet and secured thereto along a peripheral edge of said sheet.
A laminated hair curling roller assembly including an elongated roller body having an arc-shaped transverse cross-sectional configuration, said body formed to provide substantial resistance to bending and buckling when subjected to finger force and said body comprising;
- a. a first sheet of a thickness selected to provide the principle structural member for said roller body, said first sheet having a plurality of apertures formed therethrough;
- b. a sheet of liquid absorbing material coextensive with said first sheet and positioned adjacent said first sheet;
- c. a second non-perforated sheet of liquid impervious material coextensive with said first sheet and positioned adjacent said liquid absorbing sheet and spaced thereby from said first sheet, said second sheet sealed with the liquid absorbing sheet to said first sheet to form an enclosure therebetween;
- d. means positioned between said second sheet and said liquid absorbing sheet for creating an exothermic reaction when activated by fluid absorbed by said absorbing sheet and entering said enclosure through the apertures formed in said first sheet;
- and
- e. means provided in said absorbing sheet for venting said exothermic reaction through said apertures formed in the first sheet.
A laminated hair curling roller assembly including an elongated roller body having an arc-shaped transverse cross-sectional configuration, said body formed to provide substantial resistance to bending and buckling when subjected to finger force and said body comprising;
- a. a first sheet of a thickness selected to provide the principle structural member for said roller body, said first sheet having a plurality of apertures formed therethrough;
- b. a sheet of liquid absorbing material co-extensive with said first sheet and positioned adjacent said first sheet;
- c. a second sheet of liquid impervious material co-extensive with said first sheet and said liquid absorbing sheet and positioned adjacent said liquid absorbing sheet and spaced thereby from said first sheet, said second sheet sealed with the liquid absorbing sheet to said first sheet to form an enclosure therebetween;
- d. means positioned between said second sheet and said liquid absorbing sheet for creating an exothermic reaction when activated by fluid absorbed by said absorbing sheet and entering said enclosure through the apertures formed in said first sheet;
- e. means provided within said enclosure for entrapment of particles which form as a result of exothermic reaction;
- and
- f. means positioned on said liquid absorbing sheet in alignment with said apertures for venting said enclosure and including a plurality of areas on said absorbing sheet treated with a hydrophobic material to form non-liquid absorbing segments in said absorbing sheet.
A laminated hair curler assembly comprising;
- a. a first sheet formed of a liquid impervious material and having a plurality of apertures formed in a thickness thereof;
- b. a second sheet formed of a liquid impervious material having a surface area extending substantially coextensively with the surface area of the first sheet and sealed with said first sheet to provide an enclosure therebetween into which a reaction activating liquid can flow through said apertures;
- c. a sheet of liquid absorbent material positioned between said first and second sheets and including hydrophobic segments positioned adjacent said apertures of the first sheet;
- d. means positioned between said absorbent sheet and said second sheet for creating an exothermic reaction when activated by a fluid in said enclosure;
- and
- e. said assembly formed into an elongated body having an arc-shaped cross-sectional configuration.
