Claim 1
Independent Claim
231 words
A hairdressing kit comprising: a hair dryer having a cylindrical air blower portion; at least one cylindrical hair curler; and a casing for holding said hair dryer and said hair curler, said casing having a dish-shaped main case, a dish-shaped internal frame therewithin spaced from an inner surface of said main case to define an air space between said main case and said internal frame, an upper case mounted over said main case and having a blower receiving cylindrical recess for receiving the blower portion of said hair dryer and at least one curler receiving recess for receiving a curler, and a mounting frame within said upper case and mounted over said internal frame, said mounting frame having a cylindrical mounting portion for receiving and supporting said blower through said blower receiving cylindrical recess and a further cylindrical mounting portion for receiving and supporting a curler through said curler receiving recess, said mounting frame defining with said internal frame an air passage extending along said internal frame from said blower receiving cylindrical recess to said curler receiving recess, said air passage being completely enclosed relative to said air space, said air space acting as an insulating space between said internal frame defining said air passage and the exterior of said casing to reduce escape of heat from hot air being blown along said air passage from said dryer to a curler.
