  • Publication number: 20100012143
    Abstract: The invention relates to a hairstyling device (1) comprising two jaws (2, 3), each supporting at one end a treatment surface (10, 11), at least one of which includes a heating element, said jaws (2, 3) being mounted so as to pivot about a hinge (4) at the other end between an open position that allows the hair to be inserted between the two treatment surfaces (10, 11) and a closed position for placing it in contact with the two treatment surfaces (10, 11), said jaws (2, 3) forming two handle halves (5, 6) between the treatment surfaces (10, 11) and the hinge. According to the invention, the device (1) includes return means for the handle halves (5, 6), which cause pressure to be applied to the treatment surfaces (10, 11).

  • Patent number: 6076984
    Abstract: A depilatory wax dispenser having a housing (1) in which is arranged a reservoir (2) for the wax and an applicator device having a roller (5) mounted for rotation on a pivot pin (7). The pivot pin has two ends which extend through two opposite transverse walls (4a, 4b) of a rectangular opening (4) provided at the reservoir (2) outlet. The opening (4) has an edge which provides with the roller (5) peripheral surface a slot dispensing melted wax. The opening (4) edge and the roller (5) peripheral surface between which the slot is arranged are made of elastically deformable materials. An element (10) is axially mobile relative to the pivot pin (7) for simultaneously exerting a force on the rectangular opening (4) edge forming the slot and on the roller (5) surface, for deforming them jointly.

  • Patent number: 5846326
    Abstract: An applicator for a meltable product comprising: a case, a reservoir for holding a quantity of the product, the reservoir having an outlet opening and being made at least in part of a thermally conductive material, heating device in thermal communication with the reservoir, and an applicator roller disposed in the outlet opening, wherein the applicator roller comprises a core composed at least partly of thermally conductive material and a layer of plastic material surrounding the core. An applicator in combination with an extraction gripper for gripping the roller, the gripper comprising two arms which extend substantially parallel to one another, each arm having a projecting finger positioned such that the projecting finger on one of the arms faces the projecting finger on the other one of the arms, the projecting fingers being located and configured to cooperate with the engagement elements of the roller in order to grip the roller.
