Patent number: 6076984Abstract: 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.Type: GrantFiled: July 8, 1999Date of Patent: June 20, 2000Assignee: SEB S.A.Inventors: Marc Legrain, Sylvie Lacombe
