Abstract
A heatable hair curler includes an elongate casing, an interior cavity, and a heat absorbent material. The elongate casing is made of a flexible material and has an axial length of at least about 7.5 inches and a width of at least about 1.25 inches. The casing has opposite first and second ends that are attachable to each other. The interior cavity is located between the first and second ends and is separated from the first and second ends by first and second seams, respectively. The heat absorbent material substantially fills the cavity.
Claims21
A heatable hair curler comprising:
- an elongate casing of flexible material having an axial length of at least about 7.5 inches and a width of at least about 1.25 inches, the casing having a first flat end portion, a second flat end portion opposite the first flat end portion, and a center portion located between the first and second flat end portions, the first and second flat end portions being attachable to each other, the flexible material consisting essentially of a fire-retardant fabric capable of withstanding temperatures of at least about 250° F.;
- an interior cavity defined by the center portion, a first end of the center portion bounded from the first flat end portion by a first seam and a second end of the interior cavity bounded from the second flat end portion by a second seam;
- and
- silica beads of at least about 0.05 millimeters in diameter filling the cavity from the first end to the second end of the center portion, the silica beads being retained in the center portion by the first and the second seams.

A hair curler for curling human hair, the hair curler comprising:
- a flexible, rod-shaped housing made of a fire-retardant material capable of being heated to at least about 600° F. the housing having an axial length of at least of about 7.5 inches and a width of at least about 1.25 inches, the housing having a first flat end portion and a second flat end portion, the first and second flat end portions being attachable to each other;
- a center body portion located between the first and second flat end portions of the housing and formed from the fire-retardant material, the center body portion having a circumference of about 2.5 inches, the center body portion having a first end bounded from the first flat end portion by a first seam and a second end bounded from the second flat end portion by a second seam;
- and
- a heat absorbent material filling the center body portion from the first end to the second end, the heat absorbent material being retained in the center body portion by the first and the second seams, the heat absorbent material absorbs moisture at room temperature and expels moisture when heated to approximately 250-350° F., wherein the heat absorbent material is silicia in the form of beads of at least about 0.05 millimeters in diameter.
