Definitions

• the present invention relates to a hot melt depilatory wax dispenser.
• Wax removal devices are known in which the wax is melted and then spread on the skin, and after solidification removed, which makes it possible to pull out the hairs embedded in the layer of hardened wax.
• the wax is melted in a tank, then spread on the skin with a roller applicator disposed in an opening placed at the outlet of the wax tank, a calibrated space being provided between this opening and the roller. This is entrained by applying it against the skin and moving the device, thus forming a layer of wax of determined thickness and width which is deposited on the skin.
• the generally cylindrical shape of the rollers used for applying the wax is not always suitable. This is particularly the case under the armpits where, given the concavity of the surface on which the wax is to be applied, the edges of the cylindrical roller rub against the skin, impairing comfort and efficiency, the edges of the wax layer being more stressed under pressure, which reduces their thickness.
• GB-363 744 has already proposed an adhesive applicator using a roller mounted to pivot in a rectangular opening.
• the applicator roller is made of an elastically deformable material, so that by pressing on this roller its deformation makes it possible to break the film of hardened glue.
• these devices are not suitable for applying these products to more or less flat surfaces, so that several devices or a device with a removable application head are then required.
• the latter solution has already been proposed, in particular for adapting rollers of different widths, however this is an unsuitable solution, requiring handling of heads stuck with wax.
• duplicators for glue or cosmetic products comprising either a flexible housing or a flexible applicator roller support, or even a flexible nozzle, to ensure either a closing or an opening of the reservoir of product to be dispensed, or a variable flow, depending on the deformation applied to the flexible part.
• an applicator for a liquid, viscous or pasty product provided with an applicator comprising a cap having an outlet slot in which engages a deformable tongue which releases more or less product .
• the object of the present invention is to remedy, at least in part, the above-mentioned drawbacks, by a simple solution both from the point of view of manufacture and of use, while being reliable and robust.
• the invention relates to a dispenser of hot-melt depilatory wax
• a dispenser of hot-melt depilatory wax comprising a housing forming a gripping means, inside which is provided a reservoir for the wax associated with heating means and an application device.
• a roller rotatably mounted on a pivot shaft the ends of which extend through two opposite transverse walls of a rectangular opening formed at the outlet from said tank, the edge of this opening forming with the peripheral face of this roller a slot distribution of the melted wax following the rotation of this roller
• the edge of said opening and the peripheral surface of the roller between which said slot is made are of elastically deformable materials.
• This device comprises means movable axially relative to the axis of said pivot shaft to simultaneously exert a force on the edge of the rectangular opening forming said slot and on the surface of said roller, able to deform them jointly, so as to modify the profile of said slot.
• one of the transverse walls of said opening is fixed along said shaft, while the other is mobile, pivoting means (for example a ball bearing) being interposed between each of these transverse faces and one of the ends of said roller, said axially displaceable means comprising a nut, adjacent to the external face of the movable transverse wall of said rectangular opening, engaged with a thread, for moving this movable wall as well as the adjacent end of said roller towards the opposite wall.
• the pivoting means allow the roller to rotate freely despite the pressure transmitted by the transverse walls of the opening on the end walls of the roller to deform its peripheral wall.
• the transverse walls of the opening, as well as the end faces of the roller are substantially non-deformable relative to the longitudinal walls of this opening and to the peripheral face of said roller.
• This "rigidity" of the transverse walls of the opening and of the end faces of the roller makes it possible to use these faces effectively to uniformly transmit the force of the axially movable means to deform the edges of the opening and the peripheral face of the roller.
• the peripheral wall of said roller has the form of a tubular element, the two ends of which are integral with rigid flanges.
• This peripheral wall of the roller formed by an elastically deformable tubular element between two rigid flanges facilitates the deformability of the roller. It can also allow, when the roller is not compressed axially by the axially displaceable means, to curve slightly in contact with a convex surface.

• FIG. 2 is a sectional view along ll-ll of FIG. 1,
• FIG. 3 is a partial sectional view, along III-III of FIG. 2, of the application device in a first position
• Figure 4 is a view identical to Figure 3, of this application device in a second position.
• the wax distributor illustrated in the drawing comprises a housing 1, inside which is a reservoir 2 intended to receive the depilatory wax.
• An electric heating body 3 is fixed to one of the walls of this tank 2 inside which extends a heat diffusion fin 2a.
• a rectangular opening 4 is formed at the top of this tank 2 and is formed through a support piece 6 closing the upper end of the tank 2.
• a wax applicator device is disposed in the opening 4 of this reservoir 2.
• This applicator device comprises a roller 5, the peripheral face of which is formed of a tubular element 5a made of an elastically deformable material, closed at its two ends by two flanges 5b, 5c, preferably rigid with respect to the tubular element 5a.
• This roller 5 is pivotally mounted on a shaft 7 freely passing through the flanges 5b, 5c and the two ends of which are mounted through the two transverse walls 4a, 4b (FIG. 3) of the rectangular opening 4.
• a slot is made on each side of the peripheral face of the roller 5.
• These slots are delimited by the edges 4c, 4d of the opening 4 and the peripheral wall of the roller 5, allowing the melted wax leaving the reservoir 2 in the form of a thin layer, following the rotation of the roller 5.
• the wax can exit through one or the other slot according to the direction of rotation of the roller 5.
• the transverse walls 4a, 4b of the rectangular opening 4 formed through the support 6 are relatively rigid, while its longitudinal walls 4c, 4d are elastically deformable. This result can be obtained in different ways, for example, by molding the support 6 in a flexible material, such as a thermoplastic elastomer, and by placing in the mold a relatively more rigid frame in the walls 4a, 4b.
• Two ball bearings 8, 9 are disposed respectively between the transverse face 4a of the opening 4 and the end face 5b of the roller 5 and between the transverse face 4b of the opening 4 and the end face 5c of the roller 5.
• One end of the shaft 7 ends with a head 7a which bears against the external face of the transverse wall 4a, while the other end of this shaft 7 has a thread engaged with a nut 10 pressing against the external face of the transverse wall 4b of the opening 4.
• This nut 10 is integral in rotation with a control button 11. Therefore, by screwing the nut 10 He along the shaft 7 in the direction of the other end ending with the head 7a, pressure is exerted on the face 4b and as the opposite face 4a is retained by the head 7a, the displacement of the nut 10 produces a joint deformation of the edges 4c, 4d of the opening 4 and of the peripheral wall of the roller 5, as illustrated in FIG. 4. This joint deformation therefore makes it possible to maintain a distribution slot of substantially constant width between the peripheral face of the roller 5 and the opening 4.
• the flexible material used for the roller 5 makes the contact with the skin softer and therefore more pleasant.
• the peripheral wall of. this roller 5 is produced using a flexible tubular element 5a, allowing it to more closely match the profile of the surface to which the wax is to be applied, when the peripheral surface of the roller 5 is not placed under tension by the nut 10. In fact, when the roller 5 is used in the unsolicited state, as illustrated by FIG. 3, its peripheral surface can follow, to a certain extent, the profile of the surface on which the wax should be deposited, for example, a slight convexity of this surface.
• the invention finds its application in the field of wax hair removal devices and more particularly in that of consumer devices.
