    Patent number: 5076299
    Abstract: A bobbin or spool type hair curler having a cylindrical hair roller portion formed between a pair of opposing parallel flanges and provided with a pliable, integrally formed, cup-shaped closure member. The closure member is axially aligned to one of the end flanges of the spool shaped hair roller portion. The wall of the cup-shaped closure member extends away from the spool shaped portion and, after the hair is wound upon the spool shaped portion, the wall may be flipped substantially 180.degree. about its point of attachment to its corresponding flange in order to place the rim of the cup-shaped closure member proximate to the other flange to thereby retain the hair around the spool shaped portion. The invention additionally includes a method for curling hair with the aforementioned device and, in one embodiment the hair curler is provided with an axial throughbore and the invention further includes a method for heating same.
