Definitions
- the present invention relates to a hand held material dispenser hot-melt, in particular depilatory wax, but which can also be a cream, ointment, glue or varnish.
- a hand held material dispenser hot-melt in particular depilatory wax, but which can also be a cream, ointment, glue or varnish.
- hot melt we hears all types of material taking a solid, semi-solid or pasty at room temperature, and turning into a liquid state under the action of heat, which then allows, among other things, its spreading in thin layer.
- the material stored in solid form at room temperature can be subjected to a heat flux to switch to a fluid or even liquid state for distribution in the form of a thin layer.
- a dispenser comprises a housing forming a means of manual gripping, inside which is a longitudinal reservoir solid hot melt, such as granular wax or under the shape of a bread.
- this tank opens into a intermediate duct ending in a spout for depositing the layer directly on the application surface, or in a closed intermediate volume by a layer transfer roller.
- the tank is in thermal relation with heating means for melting then keep all of the wax melted so that once liquid, it flows out of the dispenser in the form of a strip more or thinner depending on the speed of movement of the dispenser at above the application surface: usually the user's skin.
- heating means for melting then keep all of the wax melted so that once liquid, it flows out of the dispenser in the form of a strip more or thinner depending on the speed of movement of the dispenser at above the application surface: usually the user's skin.
- roller distributor according to document FR-A-2 520 601 is previously installed in a heating sleeve within a box of support all the time necessary for all of the wax contained in the tank melts.
- the waiting time is particularly long.
- the tank made of aluminum includes a central diffusion fin, and is heated by an electrical resistor placed against one of its walls longitudinal. In this case, it is also advisable to wait until all of the wax in the tank is melted before you can use this distributor.
- a single electrical resistance is arranged in the area intermediate little above and parallel to the roller. If desired, the resistance is supplemented by a fin oriented towards the roller for also heat it. Start-up can only start when the entire wax present in the adjacent part of the tank and in the area intermediate is melted.
- the tank includes means for pushing the end of a wax stick through a nozzle hot whose temperature is controlled and whose orifice opens onto a duct intermediate ending with a spout for depositing the layer directly on the application surface or in an intermediate volume terminated by a roller layer transfer.
- the document FR-A-914 405 describes an electrical distributor for making wax seals.
- the wax is heated at its periphery and the heat is very difficult to reach the heart of the stick counts due to its low thermal conductivity.
- the heating means generally have a significant thermal inertia. This leads to locally overheat the wax to accelerate the heat transfer, so at worsen the inertial effects of the heating element, and take risks on the final application temperature.
- the object of the present invention is to provide a hand-held material dispenser hot-melt, in particular depilatory wax, in which the fusion at start-up all of the wax in granules or solid bread stored in the tank is much faster than before, this to allow a first distribution of wax as quickly as possible.
- the construction of the distributor must be such that the inertia does not affect operation, especially when this distributor ends with a direct distribution spout of the wax on the surface application or by a transfer and application roller.
- This distributor should however be kept as simple as possible to ensure reliable operation over time and to maintain production and installation costs at a reasonable level.
- a hand-held dispenser of hot-melt material in particular depilatory wax, comprising a casing forming a means of manual gripping inside which a material reservoir is provided solid hot melt in granules or in the form of a bread as well as means for heating this hot-melt material because all or part of it (starting) of these heating means is arranged so substantially homogeneous either in the entire volume of the tank, or in one or several surfaces likely to pass through substantially movably the whole tank.
- homogeneous arrangement in a plane or a volume is meant a arrangement by which the heating means are substantially identical, uniforms, per unit area or volume to provide heating practically constant at each point of the plane or volume.
- these additional heating means being on the one hand homogeneous, and residing on the other hand in or passing through the entire wax bar, can then be particularly powerful so as to melt very quickly without risk this wax when the dispenser starts.
- these means of internal tank heater starters can be stopped and set aside to let the wax flow towards the outlet, lateral heating means conventional then ensuring the simple maintenance of the wax in the molten state.
- these internal heating means can themselves be set up at a lower power of simply keeping the wax in the molten state.
- section longitudinal front view a longitudinal surface parallel to the largest vertical side, by “longitudinal section seen from the side” a longitudinal surface parallel to the lateral side corresponding to the thickness of the tank and the bread wax, and by “cross section” a surface perpendicular to the vertical axis longitudinal.
- the closed side of the tank opposite the outlet will be called “background”.
- the heating means are presented in the form of a grid formed of resistive heating wires initially arranged against one of the sides of the tank and liable to move to the other opposite side.
- the homogeneous heating means then boil down to a simple resistance heating with mesh or parallel wires easy to make and leaving passages for the wax once it has melted.
- the heat dissipated by this grid is easily controllable depending on the intensity of the current flowing through it.
- the wax goes to through the grid allowing it to progress towards an area still not melted.
- the temperature of the grid is regularized automatically at a value slightly above the melting point of the wax, the electrical power supplied conditioning the quantity of melted wax per unit of time, so the speed of movement of the grid through the bread. Of more, this resistance may be thin, therefore not very inert thermally.
- the section transverse is constant all along the tank and the heating means are a transverse grid with meshes of equal or slightly dimensions lower than those of the section, this grid being moved from the bottom of the tank to the outlet, then back to the bottom, by means of moving the grid.
- This arrangement resembles that of a piston in a syringe is relatively logical and proven.
- the displacement means comprise a rod passing through the bottom of the tank and coupled either by an articulated rod, or by a slide transverse to a crankshaft or to an eccentric stud of an animated wheel in rotation by a spring or electric motor.
- This mechanism is relatively simple and lends itself rather well to mass production at reduced costs.
- the rod comprises a first conductive part connecting in the grid permanently at an electrical supply contact located at the passage of the rod through the bottom of the tank, followed by a second insulating part connected to the connecting rod or the slide, the periphery of the grid being in contact with the metal walls of the tank.
- a limit switch is arranged near neutral bottom of the connecting rod, slide or lug, to stop the heating of starting power when the grid is back at the bottom of the tank, and, if desired, to trigger a supplementary heating for the maintenance of the molten wax.
- the means of heaters include a longitudinal grid consisting of a series of bimetallic strips close parallels arranged side by side between two electrodes extending respectively along two opposite edges of the grid.
- the grid consists of a single sinusoidal bimetallic strip passing alternately from one support along one edge to another support along the opposite edge.
- bimetallic strip is meant a strip formed by two integral metal strips, for example joined flat, and each having a coefficient of expansion different, such as steel and copper, so that this bimetallic strip bends under the effect of heat, especially that dissipated by electrical energy crossing.
- the width, therefore the resistivity, of the bimetallic strip (s) is slightly variable in the direction of the length of the grid, this width being however identical within each successive surface section extending from side edge to the other of the grid.
- the value of the substantially constant heating means within a on the other hand is modulated along the grid in according to the volume of wax to be melted, that is to say according to the thickness of the tank and / or wax bread, in correspondence with this section.
- This characteristic finds all its advantage in the case of section tank transverse moving longitudinally.
- the longitudinal section seen from the side of the tank is lens-shaped, and the longitudinal bimetal grid is articulated in rotation around the first lateral support / electrode, or around an axis adjacent parallel, at the outlet of the tank, for example at the level of the roller axis, the opposite lateral support / electrode being guided in longitudinal sliding at the bottom of the tank; or vice versa the first support / electrode being articulated at the bottom of the tank.
- the longitudinal section seen from the side of the tank becomes triangular at its bottom, and the bimetal grid longitudinal is fixed only at the bottom of the tank by its support / electrode corresponding side.
- the outlet of the tank can give on a transfer and application roller mounted on a retractable cradle rotation or translation. This arrangement makes it easy to load the wax into the tank by passing it through the wide outlet.
- the heating means are a wire resistive electric heater arranged in a bundle of loops substantially homogeneous in the volume of the tank.
- the heating means can be a loose foam in resistive electric heating material, this foam being supplied by two opposite electrodes.
- loose foam is meant a foam which, at the opposite of a tight foam, has large communicating cells, therefore very high porosity.
- This type of metallic foam is for example already used in the field of battery electrodes.
- the heating means thus already being present at every point of the block of wax, it can be melted extremely quickly in one piece application of adequate electrical power. We can then describe it as a "flash" heater by analogy to the bulbs used in photography.
- the wire or the foam of the heating means are flexible, and the tank comprises means for pushing the wax towards the outlet, the means then being compressed. This allows you to use the better controlled in all positions, especially vertically with the outlet facing upwards for treatment of the armpits or the face.
- these heating means may also have low thermal inertia, i.e. they are unlikely to store calories and can cool very quickly after stopping the maintenance heater to prevent the wax from continues to flow when the dispenser is stopped.
- the reservoir is a removable cartridge cylindrical, one end of which is closed by a piston head sliding and the other end ends either with a spout or with a roller distribution, the associated distributor comprising a piston pushed forward in a cartridge receptacle, and this by a spring under the control of a mechanism.
- the cartridge usefully has an upper flange of attachment to the distributor, this flange also having an insulation function wax for the dispenser.
- this distributor control mechanism may include a wire coming to be wound on a drum driven by an internal spiral spring when the piston spring is compressed, as well as a drum retaining lever when the wire unwinds being driven by the piston pushed by the spring.
- This fairly simple but efficient and reliable design mechanism lends itself fairly good to mass production at reduced costs, especially because the most parts can be molded from plastic.
- Figures 1a and 1b is illustrated a first variant of a dispenser depilatory wax whose heating means for melting the wax are based on a first embodiment corresponding to a mobile heating grid through the tank.
- This dispenser includes an external housing 10 for gripping by hand, in the substantially parallelepipedic occurrence.
- a reservoir 12 of wax 5 also parallelepiped closed in its lower part by a bottom and closed in its upper outlet by a transfer and application roller 20.
- This tank is preferably made of heat-conductive metallic material, by example of aluminum.
- the roller 20 is in the form of a cylindrical plastic sleeve mounted on a metal core.
- the characteristics of the plastic of the sleeve are chosen according to those of the wax, in particular its wettability, to entrain this wax in the form of a strip and deposit it on the surface of application, in this case the skin of the user.
- the metal core provides heat transfer by conduction to maintain the wax strip transferred in a pasty state to the application surface.
- this roller 20 is mounted between the two ends of the branches of a cradle 22 U-shaped articulated in rotation at its central crosspiece. This roller can therefore be retracted upwards by rotating the cradle to release of the tank outlet surface 12. In the closed position, the roller and cradle are held by two snaps 24 of locking arranged in the extension of each of the ends of the axis roller rotation.
- a maintenance heating resistor 30 is placed against one of the most wide longitudinal walls of the reservoir 12, the other opposite wall being joined against an internal face of the housings 10. This heating element 30 ensures the maintenance in the liquid state of the wax 5 contained in the reservoir 12 once it fondue.
- the melting of the wax contained in the tank is provided by a grid special heater 32 held in the middle by the upper end of a push rod 40 so as to be movable from the bottom of the tank towards the outlet, then back.
- this rod 40 passes through a cylindrical sleeve 11 formed in the center from the bottom of the tank 12.
- this sleeve provides also a sealing function between the rod and the reservoir opposite the melted wax.
- the upper part of the rod 40 namely that caused to pass through the sleeve when moving the grid in the tank is electrically conductive: either it is coated with a layer metallic, either that it consists of a solid metal rod; the lower part being made of an insulating material such as plastic. Therefore the sleeve 11 includes a gasket 13 also serving as an electrode power supply to the heating grid 32 through this part upper conductive rod 40, the return of the current being effected by the metal of the tank 12.
- the transverse heating grid 32 can be produced in the form of a wide-mesh weaving of resistive electrical wires, or even a metal plate molded with a network of through cells.
- the dimensions of this grid correspond to those of the internal section of the tank so as to obtain permanent friction with the walls without jamming.
- the material and / or the thickness of this grid are set so that they are relatively rigid in their sides, that is to say that they do not flex too much in their peripheries when pushed into their surroundings.
- the means of displacement of the rod 40, therefore of the heating grid 32 at within the reservoir 12, are based on a mechanism transforming a rotary drive movement from a motor in a movement of alternative translation.
- this mechanism first includes a transverse slide 42 mounted at the lower end of the rod 40, this slide having a transverse oblong groove or opening. In this groove is engaged a stud 43 secured to the periphery of a wheel 44 whose central axis is held, free to rotate, at the end of an extension lower tank support 12. This pin 43 is therefore offset by relative to the axis of rotation of the wheel.
- a spiral spring 45 coaxial with the wheel is fixed on the one hand on a gear 46 mounted free in rotation on the axis of the wheel and on the other hand, against the internal face of a rear flange of the wheel 44, this flange forming a protective housing for this spiral spring.
- This gear 46 is engaged with a pinion secured to an axis passing through the case 10 and ending with a button 47 or other crank.
- This button allowing to manually apply a rotation to the gear 46 that in only one direction called “arming", the other direction being blocked by a pawl acting on button, pinion or gear.
- the wheel 44 is itself retained by a second ratchet to prevent it from turning unexpectedly when the spring hairspring 45 is somewhat tight.
- a switch 49 is arranged near the lower end of the wheel 44 of so as to be tilted by the transverse slide 42 when it is located in its bottom dead center as shown in Figure 1.
- the pair of figures 2a illustrates how the roller 20 can be retracted out from the outlet of the tank 12 by rotation up its cradle 22.
- the user acts on the button or the external handle 47 to tension the internal spiral spring 45.
- the user then acts on the second pawl to release the wheel 44 which, under the influence of the spring 45, begins to rotate then driving the longitudinal central rod 40 upward pushing the grid 32 against wax.
- the lower switch 49 toggles then triggering the grid power supply.
- the grid supplied with a strong electrical power heats up quickly, but evenly, the entire slice of wax bread or granules in contact.
- This slice of wax melts and then quickly becomes liquid, which allows it to pass through grid mesh to flow to the bottom of the tank, the grid pushed by its stem coming immediately into contact with the next slice again solid.
- This next slice also melts very quickly to drain also through the grid.
- This process is continuously developing, and we notes that the grid is progressing at substantially constant speed on both sides and on the other side of the tank. Above all, thanks to this progressive advance of the grid, the temperature thereof is automatically adjusted to a higher value only a few degrees to that of melting the wax.
- the speed of progression of this grid in the wax bread basically depends on the melting speed of successive slices itself dependent on the electrical power applied to the grid.
- the grid temperature regulating automatically we can afford to apply strong power to it to accelerate this fusion, so decrease the waiting time.
- the pair of figures 2c illustrates how the continued rotation of the wheel 44 brought the grid to the bottom by ironing through the wax with which it confirms the merger.
- the transverse slide 42 switches back on the switch 49 which stops the electrical supply to the movable grid and which activates that for the additional heating resistance 30 for only keeping the wax in the molten state in the tank.
- the force of gravity brings the melted wax against the roller which causes a tablecloth at its periphery, the thickness of this tablecloth being calibrated by the thickness of the gap between the roller and the edge corresponding to the housing, these two elements having a calender effect.
- the invention is not strictly limited to this embodiment as described but encompasses many variations.
- a person skilled in the art can easily modify the advance and backward mechanism of the grid. If desired, it can replace the spring motor with an electric motor. He can also replace wheel 44 with its stud 43 with a crankshaft and / or replace the lower part of the rod 40 and the transverse slide 42 by a connecting rod articulated at its two ends.
- Figures 3 and 4 illustrate a second variant of a wax dispenser to depilating whose heating means for melting the wax are based on a first embodiment corresponding to a grid movable through the tank.
- heating grid 50 is arranged in a longitudinal plane of the housing 10, and in that it is formed of parallel bars side by side made of a material which deforms itself under the effect of heat.
- each bar is a bimetallic strip consisting of two different metal blades joined flat and presenting each a significantly different coefficient of expansion so that flex during temperature variations.
- this longitudinal grid is preferably produced by cutting out in a bimetal plate to form a single sinusoidal blade of shape elongated rectangular, each bar being connected in series to the next bar by a link located alternately at the upper and lower lateral edge of the wire rack.
- this grid bimetallic strips 50 has, seen from the side, an initial curvature in an arc of a circle.
- the dispenser comprises a gripping case 10 whose shape exterior is as pleasant and aesthetic as possible and containing a internal tank 16 whose longitudinal section, as seen from the side on the Figures 3a and 4a, is in the form of a lens, that is to say defined by two arcs of symmetrical circles with respect to the median plane of the distributor, these arcs of circles being substantially equal to the arc defining the curvature initial of the bimetallic strip 50.
- the upper U-shaped support 54 of grid 50 is articulated in rotation at the end of each of its lateral branches 56, and this at the level of the axis of rotation 55 of the roller 20 closing the outlet of the reservoir 16.
- the second rear support 52 of the bimetallic grid 50 is movable in sliding in a bottom groove 14 of the tank 16.
- the roller 20 is mounted at the end of a cradle 23 retraction in translation, that is to say that this roller is held in part and on the other by two plates, the lower hook edge of which slides in grooves formed in the lateral internal face of the reservoir 16, and the upper edges are folded in a U to circumvent the lateral branches of the upper support 54 of the bimetallic strip 50.
- one of the bars of the grid is partially magnetized or carries a small magnet and the housing has two flexible blade switches in correspondence in the front and rear longitudinal faces. These switches allow to detect the position of the bimetallic grid within the tank: either against the longitudinal front face: only the front switch corresponding being tilted; either in the middle of the tank: none of switches not being flipped; either against the other rear longitudinal face: only the other rear switch being flipped.
- This dispenser is used as follows.
- the bimetallic grid is located against the rear longitudinal face.
- Roller 20 is released by pulling on the cradle retraction 23 to impart a translation towards the outside.
- We can then fill the reservoir 16 with wax granules.
- the user can trigger the grid's power supply bimetallic strips which starts to heat up.
- the bimetallic grid 50 Due to its rise in temperature, the bimetallic grid 50 begins to stiffen, so press against the granules 5. The bimetallic grid continues to rise in temperature until reaching that of melting of the wax. The wax granules contact begin to melt, and, once liquid, pass through this grid. This one, continuing to deform under the influence of its high temperature, comes immediately in contact with the following still solid granules which also melt quickly. As the granules melt, the deformation of the bimetallic strip can continue, causing it to pass through continuously the entire tank until it comes to press against the opposite longitudinal front, the corresponding rocker switch so. During this deformation, the free lower support 52 has advanced then retreated within the groove 14. The supply of the heating grid is then stopped to switch on the supply of heating means complementary to keeping the wax in the molten state; for example self-regulating PTC resistive elements (i.e. with temperature coefficient positive).
- the width of the bars of the longitudinal grid bimetallic strips 50 is finer in the middle of the grid than at its two ends upper and lower.
- This grid being at this more resistive median level, it delivers more heat power, which accelerates its progression thus compensating for the fact that the wax volume is greater at this level. he the fact remains that this grid is homogeneous in the portions of successive areas defined by its width and by the units of length.
- FIG. 5 illustrates a second embodiment of a dispenser comprising a bimetallic grid 60 in which the longitudinal section seen from the side of the reservoir 18 containing the wax 5 is substantially triangular in its second lower half close to the bottom. Then, the lower support 62 of the grid 60, receiving the two connection electrodes of this bimetallic grid, the bars are also connected in series, is rigidly fixed to the bottom of the tank. On the other hand, the opposite upper support 64 is freely movable in translation to pass from the anterior side to the posterior side of the distributor during of the deformation of this grid under the effect of heat. This arrangement allows to significantly increase the volume of the reservoir 18 little outside the roller 20 mounted on its translational retraction cradle 23.
- Figures 6 and 7 illustrate a dispenser based on a second mode of production of the wax heating means according to the invention in which these heating means reside substantially homogeneously in the mass of the wax contained in the tank.
- the tank of wax is here in the form of detachable 70.71 shaped cartridges cylindrical, of rectangular cross section, and possibly circular.
- the tip upper 78 dispensing the cartridge has a longitudinal section triangular side view to end in a long slender opening a spatula allowing the spreading of the wax flat once melted.
- the upper outlet of the cartridge is closed by a transfer and application roller 79 whose two ends of the axis of rotation are held in lateral tabs cartridge.
- the spout distribution can then be conical to end in an outlet circular for depositing fine lines of wax.
- these cartridges also has a flange 72 of attachment to a dispenser described below.
- these cartridges are closed by a piston head 76 of dimensions corresponding to those of their internal section so that you can slide longitudinally while ensuring a seal opposite the wax fondue.
- this piston head 76 may have a flange rear friction device against the internal wall of the cartridges.
- the heating means are here consisting of a resistive wire 74 looped in a substantially homogeneous manner in the entire volume of wax granules 5 or the entire volume of wax bread initially present in this cartridge.
- This closure can present either a regular arrangement in several superimposed planes or, as illustrated, be seemingly random like a bunch of loops more or less wide.
- the two ends of this wire are connected to electrodes of 75 side contacts arranged on either side of the cartridge, for example in its lower part.
- a such foam can be produced, for example, by electrolysis in a metal salts of commercially available fibrous foam.
- This resistive foam is then supplied by two longitudinal electrodes vertical arranged on either side of the cartridge.
- the distributor 80 associated includes a manual gripper whose external shape rather meets aesthetic criteria and whose interior includes a longitudinal receptacle 82 behind an opening for introducing the cartridge.
- the internal shape of this receptacle 82 corresponds substantially to that of the external of the cartridge 70 except for a cylindrical lower extension closed by a base 88.
- a transverse piston upper 84 and a lower compression spring 86 resting, at the extension against the base 88 and pushing the piston 84 upwards.
- a mechanism makes it possible to control the position of the piston 84 inside the receptacle 82 when put under the pressure of its spring.
- This mechanism comprises a wire 90 coaxial with the receptacle, connected on the one hand to the piston 84 and on the other hand passing through the base 88 to come and wind around a drum 92 mobile in rotation under the effect of an internal spiral spring 94.
- a lever of retainer 96 acts like a ratchet, i.e. its short branch lower presses against the drum while its upper branch long ends with a button emerging from the housing, a push on the button releasing the lower branch out of contact with the drum 92.
- the edge of the upper dispenser introduction opening has additional fixing means to the locking collar 72 of the cartridge 70.
- the user presents the cartridge 70 in front of the opening for introducing the dispenser as illustrated in FIG. 6a.
- the piston head 76 retained by the volume of wax 5 present in the cartridge, comes to press and push the piston 84 downwards, this which on the one hand compresses the spring 86 and on the other hand authorizes a winding of the lower part of the wire 90 around the drum 92 rotating under the action of its spiral spring 94.
- This introduction is continued until the collar 72 of the cartridge comes to be placed against the periphery of the orifice introduction of the dispenser in which it is locked, for example following a quarter turn rotation if the section of the cartridge is circular, or by flexible hooks, if the section is rectangular.
- the user By action on a switch not shown, the user then triggers the electrical supply in the resistive wire 74 for heating and melting the wax.
- This fusion is all the more rapid as the filament being thin and long, it presents maximum contact surface with the wax for transmission of calories
- this wire is distributed in a substantially homogeneous manner in the mass of the wax, the heating can be established at a value strong enough to melt this wax relatively quickly without risk burns.
- a thermal sensor can measure the temperature of the wax and reduce the power supply some time after it reaches the melting temperature, and this at a value just sufficient to maintain this wax in the liquid state.
- an action on the button of the lever exhaust 96 allows the wire 90 to unwind, allowing a upward movement of the piston 84 under the action of its helical spring 86.
- the melted wax is then pushed towards the dispensing spout 78 or the roller. 79 for spreading on the skin of the user.
- This advance of the piston 84 is results in compression of the package of flexible resistive wire loops. If the exhaust lever button is released, wire 90 and piston 84 are again locked in position, which stops the wax from coming out. New support on the exhaust lever retriggers the spreading of the wax.
- the heating means are supplied with electric power from a step-down device, for example from 220 V AC to 12 V DC.
- a step-down device for example from 220 V AC to 12 V DC.
- these means also allow the electric power to be adjusted to a value predetermined according to the characteristics specific to each of the waxes used.
- Many other improvements can be made to these distributors within the scope of the claims.
- the invention finds its application in the field of hair removal devices wax and more particularly in that of consumer devices.
