Definitions

  • the invention relates to an applicator holder device which can be used in particular, but not exclusively, in the cosmetic field, using for example, a Kohi pencil pencil, liner, lipstick, eye shadow, etc.
  • applicator includes in sense of the present application, the applicators with direct application (mine) as well as the applicators with indirect application (foam flocked or not, felt, brush etc.).
  • mechanisms comprising a handle with a central pusher part, actuated by a screw thread in order to be able to selectively advance or retreat, so as to descend or ascend a mine disposed in the head (or nose) of a applicator, the lead being carried by a cup.
  • the cup is held inside by a spring in the rest position
  • the pusher When the nose is mounted on the handle, and the pusher is actuated, it pushes the lead out of the head by decompressing the spring
  • a major drawback of this type of device is that, if in use, the refill nose is removed without screwing the pusher mechanism back, the lead enters the nose, but the pusher remains in the high position, requiring then a manipulation to put it back in the low position. Furthermore, the pusher mechanism being actuated by a screw thread formed in the internal surface of the handle, it is difficult to impart to the pencil a shape other than circular due to the thicknesses of material generated. Finally, such mechanisms use a large number of parts, which significantly increases the cost of these devices.
  • the drive mechanism which constitutes a fragile part of the device, is not carried by the removable head, but by the body, or by an operating member intermediate, which forces the entire device to be replaced in the event of damage to the drive mechanism
  • an applicator-carrying device comprising a case inside which is mounted a pusher mechanism capable of coming into engagement with drive means for selectively moving from a position of rest inside the case, in an active position in which the pusher mechanism is capable of driving an applicator which can move in translation in an axial channel formed in a head removably mounted on said case, means for, when removing the head from the case, automatically disengaging the drive means of the push mechanism and under the effect of an axial force exerted by return means causing the push mechanism to move from the active position to said rest position, characterized in that the drive means have an elasticity, an axial component of which exerts on the pusher mechanism, in the position of th ngagement with the drive means, in response to an axial pressure exerted on the pusher mechanism, via the applicator, an axial restoring force of opposite direction to the direction of the axial force exerted by restoring means

  • the applicator returns to position, by elastic return, as soon as the pressure ceases
  • the drive means consist of at least one member in the form of two parts, a first part secured to the head, on which it is mounted with radial elasticity, to selectively allow the setting in engagement (respectively disengagement) of the drive means with the pusher mechanism, a second part, integral with the first, capable of coming into engagement with the pusher mechanism, and having an axial elasticity to generate said axial restoring force

Description

DISPOSITIF PORTE-APPLICATEUR APPLICATOR HOLDER
L'invention concerne un dispositif porte applicateur pouvant être utilisé notamment, mais pas exclusivement, dans le domaine cosmétique, utilisant par exemple, une mine crayon Kohi, liner, rouge à lèvres, ombre paupières, etc.. Le terme « applicateur » englobe au sens de la présente demande, les applicateurs à application directe (mine) ainsi que les applicateurs à application indirecte (mousse floquée ou non, feutre, pinceau etc.).The invention relates to an applicator holder device which can be used in particular, but not exclusively, in the cosmetic field, using for example, a Kohi pencil pencil, liner, lipstick, eye shadow, etc. The term "applicator" includes in sense of the present application, the applicators with direct application (mine) as well as the applicators with indirect application (foam flocked or not, felt, brush etc.).
Dans le domaine cosmétique, on connaît des mécanismes comportant un manche avec une partie poussoir centrale, actionnée par un pas de vis pour pouvoir sélectivement avancer ou reculer, de manière à descendre ou remonter une mine disposée dans la tête (ou nez) d'un applicateur, la mine étant portée par une cupule. La cupule est maintenue à l'intérieur par un ressort en position de repos Lorsque le nez est monté sur le manche, et que l'on actionne le poussoir, celui-ci pousse la mine hors de la tête en décomprimant le ressortIn the cosmetic field, mechanisms are known comprising a handle with a central pusher part, actuated by a screw thread in order to be able to selectively advance or retreat, so as to descend or ascend a mine disposed in the head (or nose) of a applicator, the lead being carried by a cup. The cup is held inside by a spring in the rest position When the nose is mounted on the handle, and the pusher is actuated, it pushes the lead out of the head by decompressing the spring
Un inconvénient majeur de ce type de dispositif, tient au fait que , si en cours d'utilisation, on retire le nez recharge sans revisser en arrière le mécanisme poussoir, la mine rentre dans le nez, mais le poussoir reste en position haute, requérant alors une manipulation pour le remettre en position basse. Par ailleurs, le mécanisme poussoir étant actionné par un pas de vis ménagé dans la surface interne du manche, il est difficile de conférer au crayon une forme autre que circulaire en raison des épaisseurs de matière engendrées. Enfin, de tels mécanismes mettent en oeuvre un grand nombre de pièces, ce qui augmente de manière non négligeable le coût de ces dispositifs.A major drawback of this type of device is that, if in use, the refill nose is removed without screwing the pusher mechanism back, the lead enters the nose, but the pusher remains in the high position, requiring then a manipulation to put it back in the low position. Furthermore, the pusher mechanism being actuated by a screw thread formed in the internal surface of the handle, it is difficult to impart to the pencil a shape other than circular due to the thicknesses of material generated. Finally, such mechanisms use a large number of parts, which significantly increases the cost of these devices.
D'autres dispositifs porte-applicateurs sont décrits également dans le brevet US 3358699 ou dans les demandes de brevet EP-A-0604793 ou DE-A-4222759. Les dispositifs décrits dans ces documents sont du type comprenant une tige filetée avec laquelle sont mises en engagement une ou plusieurs pattes, de manière à entraîner l'applicateur en position de sortie Toutefois, ces dispositifs posent des problèmes principalement en ce que, en raison du mécanisme qui l'entraîne, l'applicateur est maintenu axialement de façon rigide, ce qui provoque inévitablement un certain manque de souplesse à l'application, manque de souplesse perçu de manière rédhibitoire par les consommatrices, lorsque le dispositif est utilisé pour l'application de produits de maquillage dans des zones aussi sensibles que celles entourant les yeux.Other applicator holder devices are also described in US patent 3358699 or in patent applications EP-A-0604793 or DE-A-4222759. The devices described in these documents are of the type comprising a threaded rod with which one or more tabs are engaged, so as to drive the applicator in the outlet position. However, these devices pose problems mainly in that, due to the mechanism which drives it, the applicator is held axially rigidly, which inevitably causes a certain lack of flexibility on application, perceived lack of flexibility of prohibitive way by consumers, when the device is used for applying makeup products in areas as sensitive as those surrounding the eyes.
Par ailleurs, dans les documents EP-A-0604793 et US 3358699, le mécanisme d'entraînement, qui constitue une partie fragile du dispositif, n'est pas porté par la tête amovible, mais par le corps, ou par un organe de manoeuvre intermédiaire, ce qui oblige au remplacement de l'ensemble du dispositif en cas d'endommagement du mécanisme d'entraînementFurthermore, in documents EP-A-0604793 and US 3358699, the drive mechanism, which constitutes a fragile part of the device, is not carried by the removable head, but by the body, or by an operating member intermediate, which forces the entire device to be replaced in the event of damage to the drive mechanism
Enfin, dans le cas du document DE-A-4222759, la partie entraînante du mécanisme, lors du montage de la tête sur le corps du dispositif, est mise en engagement avec la tige filetée, sensiblement en son milieu Ceci oblige, en raison des faibles espaces annulaires, le franchissement en force d'une portion substantielle du filetage par les moyens d'entraînement, en position contrainte de ceux-ci, lequel franchissement en force affecte de manière sensible la simplicité et la douceur du montage et de l'utilisation du dispositif, et risque par ailleurs d'endommager de manière irrémédiable, soit le mécanisme d'entraînement, soit le filetage, soit les deuxFinally, in the case of document DE-A-4222759, the driving part of the mechanism, during the mounting of the head on the body of the device, is engaged with the threaded rod, substantially in its middle. small annular spaces, the force crossing of a substantial portion of the thread by the drive means, in the constrained position thereof, which force crossing significantly affects the simplicity and smoothness of the mounting and use of the device, and may also irreparably damage either the drive mechanism, the thread, or both
Aussi, est-ce un des objets de la présente invention que de réaliser un dispositif porte- applicateur, éventuellement rechargeable, et ne présentant pas les inconvénients mentionnés ci-avant en référence aux dispositifs conventionnelsAlso, is it one of the objects of the present invention to provide an applicator holder device, possibly rechargeable, and not having the drawbacks mentioned above with reference to conventional devices
C'est en particulier un objet de l'invention que de fournir un dispositif porte-applicateur dans lequel l'applicateur est entraîné par un mécanisme simple, fiable et qui confère à l'application une douceur et une souplesse améliorées par rapport aux dispositifs conventionnelsIt is in particular an object of the invention to provide an applicator-carrying device in which the applicator is driven by a simple, reliable mechanism which gives the application improved softness and flexibility compared to conventional devices.
C'est en particulier un objet de l'invention que de fournir un mécanisme bon marché, d'un montage simple, pouvant présenter n'importe quelle forme et qui permette avantageusement de faire revenir automatiquement le mécanisme poussoir en position de repos lorsque l'on retire la tête de l'étuiIt is in particular an object of the invention to provide an inexpensive mechanism, of simple assembly, which can have any shape and which advantageously allows the push mechanism to return automatically to the rest position when the we remove the head from the case
D'autres objets apparaîtront de manière détaillée dans la description qui suit Selon l'invention, ces objets sont atteints au moyen d'un dispositif porte-applicateur comprenant un étui à l'intérieur duquel est monté un mécanisme poussoir apte à venir en engagement avec des moyens d'entraînement pour passer sélectivement d'une position de repos à l'intérieur de l'étui, à une position active dans laquelle le mécanisme poussoir est apte à entraîner un applicateur pouvant se déplacer en translation dans un canal axial ménagé dans une tête montée de façon amovible sur ledit étui , des moyens pour, lors du démontage de la tête de l'étui, provoquer automatiquement le désengagement des moyens d'entraînement du mécanisme poussoir et sous l'effet d'une force axiale exercée par des moyens de rappel provoquer le passage du mécanisme poussoir de la position active a ladite position de repos, caractérisé en ce que les moyens d'entraînement présentent une élasticité dont une composante axiale exerce sur le mécanisme poussoir, en position d'engagement avec les moyens d'entraînement, en réponse à une pression axiale exercée sur le mécanisme poussoir, via l'applicateur, une force de rappel axiale de sens opposé au sens de la force axiale exercée par des moyens de rappelOther objects will appear in detail in the description which follows According to the invention, these objects are achieved by means of an applicator-carrying device comprising a case inside which is mounted a pusher mechanism capable of coming into engagement with drive means for selectively moving from a position of rest inside the case, in an active position in which the pusher mechanism is capable of driving an applicator which can move in translation in an axial channel formed in a head removably mounted on said case, means for, when removing the head from the case, automatically disengaging the drive means of the push mechanism and under the effect of an axial force exerted by return means causing the push mechanism to move from the active position to said rest position, characterized in that the drive means have an elasticity, an axial component of which exerts on the pusher mechanism, in the position of th ngagement with the drive means, in response to an axial pressure exerted on the pusher mechanism, via the applicator, an axial restoring force of opposite direction to the direction of the axial force exerted by restoring means
Ainsi monté, le mécanisme poussoir, et donc l'applicateur sont montes comme sur un ressort, de sorte que, en position d'application, lorsque l'extrémité libre de l'applicateur est mise en appui sur la surface à traiter, l'applicateur peur reculer elastiquement de manière à absorber une partie de la pression exercée, augmentant ainsi la douceur à l'application L'applicateur revient en position, par rappel élastique, dès que cesse la pressionThus mounted, the pusher mechanism, and therefore the applicator, are mounted as on a spring, so that, in the application position, when the free end of the applicator is supported on the surface to be treated, the applicator can retract elastically so as to absorb part of the pressure exerted, thus increasing the smoothness on application The applicator returns to position, by elastic return, as soon as the pressure ceases
Selon un mode de réalisation préférentiel, les moyens d'entraînement sont constitués d'au moins un organe sous forme de deux parties, une première partie solidaire de la tête, sur laquelle est elle montée avec une élasticité radiale, pour permettre sélectivement la mise en engagement (respectivement le désengagement) des moyens d'entraînement avec le mécanisme poussoir, une seconde partie, solidaire de la première, apte à venir en engagement avec le mécanisme poussoir, et présentant une élasticité axiale pour générer ladite force de rappel axialeAccording to a preferred embodiment, the drive means consist of at least one member in the form of two parts, a first part secured to the head, on which it is mounted with radial elasticity, to selectively allow the setting in engagement (respectively disengagement) of the drive means with the pusher mechanism, a second part, integral with the first, capable of coming into engagement with the pusher mechanism, and having an axial elasticity to generate said axial restoring force
Avantageusement, les moyens d'entraînement sont portes par la tête, ce qui permet de pouvoir leur donner une largeur radiale plus importante, augmentant ainsi leur élasticité dans le sens axial Par ailleurs, en cas d'endommagement de tout ou partie du système d'entraînement, seule la tête amovible est à changer, et non pas l'étuiAdvantageously, the drive means are carried by the head, which makes it possible to be able to give them a greater radial width, thereby increasing their elasticity in the axial direction. Furthermore, in the event of damage to all or part drive system, only the removable head needs to be changed, not the case
Enfin, cette caractéristique permet d'utiliser une tige présentant un filetage profond, épais, et permettant une avance rapide de l'applicateurFinally, this characteristic makes it possible to use a rod having a deep, thick thread, and allowing rapid advancement of the applicator
Avantageusement encore, les moyens d'entraînement sont agencés de manière à provoquer le désengagement des moyens d'entraînement du mécanisme poussoir et le passage du mécanisme poussoir de la position active à ladite position de repos, lorsque la pression axiale exercée sur le mécanisme poussoir dépasse une valeur donnée Cette caractéristique permet d'éviter que la mine soit endommagée dans le cas d'une pression trop importante exercée sur son extrémité, comme par exemple, dans le cas d'une chute accidentelleAdvantageously also, the drive means are arranged so as to cause the disengagement of the drive means of the pusher mechanism and the passage of the pusher mechanism from the active position to said rest position, when the axial pressure exerted on the pusher mechanism exceeds a given value This characteristic makes it possible to prevent the mine from being damaged in the event of excessive pressure exerted on its end, as for example, in the event of an accidental fall
Avantageusement encore, le dispositif comprend a) un étui cylindrique creux fermé en l'une de ses extrémités, b) une tige, filetée sur au moins une partie de sa longueur, et montée libre en translation à l'intérieur de l'étui, ladite tige étant immobile en rotation à l'intérieur deAdvantageously also, the device comprises a) a hollow cylindrical case closed at one of its ends, b) a rod, threaded over at least part of its length, and mounted free in translation inside the case, said rod being stationary in rotation inside
c) des moyens de rappel élastiques montés à l'intérieur de l'étui pour, en position de repos, maintenir la tige filetée en rappel contre l'extrémité fermée de l'étui, d) une tête amovible dans laquelle est ménagée un canal axial destiné à recevoir un applicateur, monté sur une cupule, ledit canal étant ouvert en ses deux extrémités, la première extrémité débouchant sur l'extérieur pour l'application du produit, la seconde permettant le montage amovible de la tête sur l'étui, e) un système d'entraînement porté par la tête ou par l'etui de manière à être mis en engagement avec le filetage de la tige lors du montage de la tête sur l'étui pour provoquer, par rotation de l'étui par rapport à la tête, l'entraînement de l'applicateur en translation dans ledit canal en vue de la distribution du produit, et f) des moyens pour permettre le désengagement du système d'entraînement de la tige lors du démontage de la têtec) elastic return means mounted inside the case for, in the rest position, keep the threaded rod in return against the closed end of the case, d) a removable head in which is formed a channel axial intended to receive an applicator, mounted on a cup, said channel being open at its two ends, the first end opening onto the outside for the application of the product, the second allowing the removable mounting of the head on the case, e) a drive system carried by the head or by the case so as to be engaged with the thread of the rod during mounting of the head on the case to cause, by rotation of the case relative at the head, the drive of the applicator in translation in said channel for the distribution of the product, and f) means for allowing the disengagement of the rod drive system during disassembly of the head
La tige peut être filetée sur tout ou partie de sa longueur Toutefois, de préférence, la tige est filetée sur une portion délimitée par une première limite située à l'opposé de l'extrémité fermée de l'étui et une second' limite, les moyens d'entraînement comportant une partie engrenante apte à ven. en engagement avec le filetage de la tige, ladite partie engrenante étant positionnée de telle sorte que, lors du montage de la tête sur l'étui, la partie engrenante soit sensiblement en regard de la première limiteThe rod can be threaded over all or part of its length. However, preferably, the rod is threaded over a portion delimited by a first limit situated opposite the closed end of the case and a second limit, the drive means comprising a meshing part capable of coming into engagement with the thread of the rod, said meshing part being positioned so that, when mounting the head on the case, the meshing part is substantially opposite the first limit
Ainsi, la partie engrenante est, en position contrainte, amenée à franchir sensiblement aucune portion du filetage, ce qui en effet provoquerait inévitablement l'endommagement du filetage, ou des moyens d'entraînement Par ailleurs, entre la seconde limite et l'extrémité de ta tige située dans le fond de l'étui, la tige peut présenter une portion dont le diamètre est sensiblement égal au diamètre du fond du filetageThus, the meshing part is, in the constrained position, caused to pass through substantially no portion of the thread, which in fact would inevitably cause damage to the thread, or to the drive means. Furthermore, between the second limit and the end of your rod located in the bottom of the case, the rod may have a portion whose diameter is substantially equal to the diameter of the bottom of the thread
Ainsi, selon cet agencement avantageux, lors du montage de la tête sur l'étui, le système d'entraînement vient en premier lieu au contact de la tige, au tout début du filetage de la tige, voire (au moins pour une des pattes) sur une partie non filetée de celle-ciThus, according to this advantageous arrangement, when the head is mounted on the case, the drive system comes first into contact with the rod, at the very beginning of the threading of the rod, or even (at least for one of the legs ) on a non-threaded part thereof
Des moyens de couplage peuvent être prévus entre la tige et l'applicateur en vue de l'entraînement de ce dernier dans le canal axial de la tête, le montage de la tête sur l'étui provoquant la mise en engagement du système d'entraînement avec la tige filetée, mais ne provoque pas l'entraînement de l'applicateur dans le canal, celui-ci n'intervenant que lors de la première utilisation du dispositif, par rotation de la tête par rapport à l'étui Ainsi, au montage de la tête, le positionnement de l'applicateur est constant, ce qui évite au montage, une sortie d'une longueur trop importante de l'applicateur, qui pourrait provoquer un endommagement de l'applicateur En d'autres termes, la mise en engagement du système d'entraînement avec la tige filetée est déconnectée de la mise en engagement de la tige et de l'applicateurCoupling means can be provided between the rod and the applicator for the purpose of entraining the latter in the axial channel of the head, the mounting of the head on the case causing the engagement of the drive system. with the threaded rod, but does not cause the applicator to drive in the channel, the latter only intervening when the device is used for the first time, by rotation of the head relative to the case. Thus, during assembly of the head, the positioning of the applicator is constant, which avoids mounting, an excessively long length of the applicator, which could cause damage to the applicator In other words, the engagement of the drive system with the threaded rod is disconnected from the engagement of the rod and the applicator
Selon un mode de réalisation préféré, la tige comporte, en son extrémité opposée à l'extrémité fermée de l'étui, un embout d'accrochage, la cupule comportant des moyens d'accrochage destinés à coopérer de manière amovible avec l'embout d'accrochage de la tige, de manière à permettre l'entraînement de l'applicateur dans ledit canal, une rotation de l'étui par rapport à la tête, provoquant l'entraînement de l'applicateur en translation dans ledit canal et l'accrochage de la tige à la cupule par fermeture des moyens d'accrochage sur ledit embout, la rotation dans le sens inverse de l'étui par rapport à la tête provoquant la remontée de l'applicateur dans le canal, des moyens étant prévus pour libérer la tige de la cupule par ouverture des moyens d'accrochage lorsque l'applicateur est remonté à l'intérieur du canal, tout en maintenant l'applicateur à l'intérieur du canal Selon un mode de réalisation préfère, l'applicateur n'est désengagé de la tige, qu'en position rentrée de l'applicateur A cet effet, lors du démontage de la tête, en position sortie de l'applicateur, le système d'entraînement est débrayé de la tige filetée avant de débrayer la tige par rapport à la cupule, ce dernier débrayage ne pouvant se produire qu'en position rentrée de l'applicateurAccording to a preferred embodiment, the rod comprises, at its end opposite the closed end of the case, a hooking end piece, the cup comprising hooking means intended to cooperate removably with the end piece attachment of the rod, so as to allow the applicator to be driven in said channel, a rotation of the case relative to the head, causing the applicator to be driven in translation in said channel and the attachment from the rod to the cup by closing the attachment means on said end piece, the rotation in the opposite direction of the case relative to the head causing the applicator to rise in the channel, means being provided to release the rod of the cup by opening the attachment means when the applicator is raised inside the channel, while keeping the applicator inside the channel. According to a preferred embodiment, the applicator is disengaged from the rod, only in the retracted position of the applicator For this purpose, during disassembly of the head, in the extended position of the applicator, the drive system is disengaged from the threaded rod before disengaging the rod relative to the cup, the latter disengaging can only occur in the retracted position of the applicator

Ainsi que représenté a la figure 1 , le dispositif porte-applicateur 1 selon l'invention comporte pπncipalement un étui 2, formant le corps du dispositif, de forme sensiblement cylindrique, d'axe X, et ferme en l'une de ses extrémités par un bouchonAs shown in Figure 1, the applicator holder device 1 according to the invention comprises pπncipalement a case 2, forming the body of the device, shaped substantially cylindrical, axis X, and closed at one end by a plug
3 qui peut être soudé sur l'étui, ou monté sur l'étui par claquage ou collage3 which can be welded to the case, or mounted on the case by snap-fitting or gluing
Avantageusement, un orifice 202 est prévu dans le bouchon de manière à permettre une reprise d'air lors de la sortie de l'applicateur en vue d'une application de produit Le mécanisme poussoir est monté à l'intérieur de l'étui 2, et comprend essentiellement une tige filetée 4 (sur au moins une partie de sa longueur) La tige 4 est située sensiblement sur l'axe de l'étui, et est solidaire d'une tête 5 (du type ailette) La tête 5 est guidée en translation dans l'étui, au moyen de rainures 6, ménagées de manière appropriée dans la surface interne de l'étui, la tige étant ainsi immobilisée en rotation La tige est par ailleurs montée à l'intérieur de l'etui au moyen d'un ressort 7 (du type hélicoïdal) dont l'une des extrémités est en butée contre une collerette annulaire 8 ménagée à l'intérieur de l'étui, et dont l'autre extrémité est en butée contre la tête 5 de la tige 4 Ainsi, en position de repos, la tige est maintenue en rappel contre l'extrémité fermée de l'étui Avantageusement, on dispose sur la tête de la tige, du coté situe en regard du fond 3, un système de ressort, du type à lames 9, par exemple, et dont la fonction est de réduire le bruit et d'amortir le choc provoque par le retour de la tige (sous l'action du ressort 7) lorsque la tête est démontée de l'étui, comme on le verra plus en détail dans la suite de la description D'autres moyens, tel que par exemple, un coussin en matériau élastique, peuvent être utilises selon l'invention pour remplacer le mécanisme à ressorts 9 Selon un mode de réalisation préfère, l'extrémité libre de la tige 4, opposée à la tête 5 comporte un embout 17 formant une surepaisseur par rapport au diamètre de la tige L'embout peut être de forme arrondie conique, ou autre et permet, comme on le détaillera par la suite, l'accrochage de la tige a la mineAdvantageously, an orifice 202 is provided in the cap so as to allow air to be taken up when the applicator leaves for a product application. The pusher mechanism is mounted inside the case 2, and essentially comprises a threaded rod 4 (over at least part of its length) The rod 4 is located substantially on the axis of the case, and is integral with a head 5 (of the fin type) The head 5 is guided in translation in the case, by means of grooves 6, appropriately formed in the internal surface of the case, the rod thus being immobilized in rotation The rod is also mounted inside the case by means of 'a spring 7 (of the helical type), one end of which abuts against an annular flange 8 formed inside the case, and the other end of which abuts against the head 5 of the rod 4 Thus, in the rest position, the rod is held in abseiling against the end closed from the case Advantageously, there is on the head of the rod, on the side located opposite the bottom 3, a spring system, of the leaf type 9, for example, and whose function is to reduce noise and d 'cushion the shock caused by the return of the rod (under the action of spring 7) when the head is removed from the case, as will be seen in more detail in the following description Other means, such as for example, a cushion made of elastic material, can be used according to the invention to replace the spring mechanism 9 According to a preferred embodiment, the free end of the rod 4, opposite the head 5 has an end piece 17 forming a excess thickness relative to the diameter of the rod The endpiece may be of conical rounded shape, or other and allows, as will be detailed below, the attachment of the rod to the mine
Ainsi qu'il apparaît aux figures 4A et 4B, la tige peut porter un filetage sur toute sa longueur (figure 4A), ou, sur seulement une partie de sa longueur (figure 4B), le ressort étant alors utilisé pour réenclencher le dispositif lorsque la tige est revenue en sa position initiale Comme on le verra plus en détail par la suite, l'emplacement et les limites du filetage sont détermines de sorte que, lors du montage de la tête 10 sur l'étui 2, la partie engrenante des pattes 23 vienne en engagement avec le filetage, au tout début de ce dernier, de manière a limiter le nombre de pas de filetage a faire franchir par les pattes sous contrainteAs it appears in FIGS. 4A and 4B, the rod can carry a thread over its entire length (FIG. 4A), or, over only part of its length (FIG. 4B), the spring then being used to reset the device when the rod has returned to its initial position As will be seen in more detail below, the location and the limits of the thread are determined so that, during the mounting of the head 10 on the case 2, the meshing part of the tabs 23 comes into engagement with the thread, at the very beginning of the latter, so as to limit the number of thread pitches to be crossed by the tabs under stress
Le dispositif selon l'invention comporte également une tête (ou nez) 10 de forme généralement allongée, de préférence effilée en l'une de ses extrémités, et a l'intérieur de laquelle est ménage un canal axial 11 dont le diamètre est adapté au diamètre d'un applicateur, telle qu'une mine 12 portée avantageusement par une cupule 14 et destinée à être montée à l'intérieur du canal L'extrémité opposée à la partie effilée de la tête comporte une partie 13, dont le diamètre externe est légèrement inférieur au diamètre interne de l'étui 2, de manière à pouvoir y être monté de manière amovible, le bord de l'étui venant en appui sur un épaulement 40 de la tête Avantageusement, la surface externe de la partie 13 comporte une gorge annulaire destinée à coopérer par claquage avec une nervure annulaire ménagée dans la surface interne de l'étui afin d'améliorer la tenue de la tête sur l'étui, lors de l'utilisation du dispositif porte-mine En sa partie opposée à l'extrémité effilée, le canal axial 11 débouche sur un portion de plus large diamètre 15 a laquelle elle est reliée par une zone de forme tronconique 16The device according to the invention also comprises a head (or nose) 10 of generally elongated shape, preferably tapered at one of its ends, and inside which is housed an axial channel 11 whose diameter is adapted to the diameter of an applicator, such as a lead 12 advantageously carried by a cup 14 and intended to be mounted inside the channel The end opposite to the part tapering of the head has a part 13, the external diameter of which is slightly less than the internal diameter of the case 2, so that it can be mounted therein in a removable manner, the edge of the case coming to bear on a shoulder 40 of the head Advantageously, the external surface of the part 13 comprises an annular groove intended to cooperate by snap-fastening with an annular rib formed in the internal surface of the case in order to improve the holding of the head on the case, during the use of the mechanical pencil device In its part opposite the tapered end, the axial channel 11 opens onto a portion of larger diameter 15 to which it is connected by a frustoconical zone 16
La tête du dispositif selon l'invention comporte également des moyens d'entraînement 23, destinés lors du montage de la tête sur l'étui, à venir en engagement avec le filetage de la vis pour, par une rotation de la tête par rapport à l'étui, faire avancer (ou reculer) la tige dans l'étui Avantageusement, et ainsi qu'il apparaît plus explicitement aux figures 5B-5E, ces moyens 23 sont portés par un organe annulaire 21 dont une partie 20 a un diamètre externe légèrement inférieur au diamètre interne de la portion 13 de plus faible diamètre de la tête 10 de manière a pouvoir être montée, par claquage, soudage, collage, ou autre technique, à l'intérieur de ladite portion 13 L'autre extrémité 22 de l'organe annulaire forme un rebord de diamètre légèrement supérieur au diamètre interne de la partie 20 de manière a venir en appui contre le bord transversal de la portion 13 Sur le bord transversal de la partie 20, on dispose deux pattes 23, déformables elastiquement et destinées à se positionner en regard de lumières correspondantes 24, ménagées dans la paroi de ta tête 10 Dans le mode de réalisation illustré, les pattes définissent une forme de L ou V dont le sommet est orienté vers l'extérieur de manière à, en absence de contrainte, s'insérer dans les lumières 24 En position démontée, le sommet des pattes émerge sensiblement au travers des lumières 24, de la manière représentée à la figure 5CThe head of the device according to the invention also comprises drive means 23, intended during mounting of the head on the case, to come into engagement with the thread of the screw for, by a rotation of the head relative to the case, advancing (or retreating) the rod in the case Advantageously, and as it appears more explicitly in FIGS. 5B-5E, these means 23 are carried by an annular member 21 of which a part 20 has an external diameter slightly smaller than the internal diameter of the portion 13 of smaller diameter of the head 10 so that it can be mounted, by breakdown, welding, gluing, or other technique, inside said portion 13 The other end 22 of the annular member forms a rim with a diameter slightly greater than the internal diameter of the part 20 so as to bear against the transverse edge of the portion 13 On the transverse edge of the part 20, there are two legs 23, elastically deformable uement and intended to be positioned opposite corresponding lights 24, formed in the wall of your head 10 In the illustrated embodiment, the legs define a shape of L or V whose apex is oriented outward so as to, in the absence of stress, insert into the slots 24 In the disassembled position, the top of the legs emerges substantially through the slots 24, as shown in FIG. 5C
Ainsi, comme il apparaît aux figures 1 et 2, lorsque la tête est montée sur l'étui, les parois de celui-ci appuient sur le sommet des pattes d'entraînement 23, de manière a les contraindre en engagement avec le filetage de la tige 4 de manière à former ecrou et pouvoir entraîner la tige dans un sens ou dans l'autre, en fonction du sens de rotation de la tête par rapport à l'étui Selon une caractéristique essentielle de l'invention, les pattes d'entraînement 23, forment une structure elastiquement déformable dont la portion 201 en engagement avec la tige confère une élasticité axiale au positionnement de la tige, et donc de l'applicateur entraîné par la tige Dans le mode de réalisation illustré, la tige est entraînée au moyen de deux pattes 23, disposées en deux points diamétralement opposés par rapport à la tige Alternativement, et bien que cette solution ne constitue pas la solution préférée, l'entraînement de la tige filetée peut se faire avec une seule patte 23 Avantageusement, les points d'engagement de chacune des pattes 23 sont légèrement décalés axialement (de l'ordre d'un tour du filetage par exemple)Thus, as it appears in FIGS. 1 and 2, when the head is mounted on the case, the walls of the latter bear on the top of the drive lugs 23, so as to force them into engagement with the thread of the rod 4 so as to form a nut and be able to drive the rod in one direction or the other, depending on the direction of rotation of the head relative to the case According to an essential characteristic of the invention, the drive lugs 23 form an elastically deformable structure whose portion 201 in engagement with the rod gives axial elasticity to the positioning of the rod, and therefore of the applicator driven by the rod In the illustrated embodiment, the rod is driven by means of two lugs 23, arranged at two diametrically opposite points relative to the rod Alternatively, and although this solution is not the preferred solution, the drive of the threaded rod can be done with a single leg 23 Advantageously, the points of engagement of each of the legs 23 are slightly offset axially (of the order of a turn of the thread for example)
Chacune des pattes présente globalement la forme d'un L présentant une première partie 200, qui, en position montée de la tête est sensiblement parallèle à l'axe X du dispositif Une extrémité de la partie 200 est solidaire de l'organe annulaire 21 (décrit en référence aux figures 5B et 5C), monté sur la tête 10 L'autre extrémité est solidaire d'une partie 201 qui lui est sensiblement perpendiculaire, et dont l'extrémité libre est destinée a venir en engagement avec la tige filetée 4 La portion 200 de chacune des pattes 23 est située en regard d'une lumière correspondante 24, apte à permettre, par rappel élastique, le désengagement des pattes 23 de la tige filetée lors du démontage de la tête En effet, lors du démontage de la tête, les pattes 23 ne sont plus contraintes par la paroi interne du corps du dispositif Les pattes 23 présentent une élasticité dont une composante radiale provoque, par rappel élastique, ie pivotement de la partie 200, sensiblement autour d'un axe A (figure 5B) perpendiculaire à l'axe X du dispositif La partie 200 pénètre, au moins partiellement, dans la fente correspondante 24 (voir figure 5C) La partie 201 s'écarte alors sensiblement radialement par rapport à la tige 4, ce qui libère la tige, laquelle, sous l'effet de la force de rappel exercée par le ressort 7, retourne en position de repos dans le fond du dispositifEach of the tabs generally has the shape of an L having a first part 200, which, in the mounted position of the head is substantially parallel to the axis X of the device. One end of the part 200 is integral with the annular member 21 ( described with reference to FIGS. 5B and 5C), mounted on the head 10 The other end is integral with a part 201 which is substantially perpendicular to it, and the free end of which is intended to come into engagement with the threaded rod 4 La portion 200 of each of the legs 23 is located opposite a corresponding lumen 24, capable of allowing, by elastic return, the disengagement of the legs 23 of the threaded rod during disassembly of the head Indeed, during disassembly of the head , the legs 23 are no longer constrained by the internal wall of the body of the device The legs 23 have an elasticity, a radial component of which causes, by elastic return, ie pivoting of the part 200, sensibleme nt around an axis A (FIG. 5B) perpendicular to the axis X of the device The part 200 penetrates, at least partially, into the corresponding slot 24 (see FIG. 5C) The part 201 then deviates substantially radially from the rod 4, which releases the rod, which, under the effect of the restoring force exerted by the spring 7, returns to the rest position in the bottom of the device
La portion 201 qui, au montage de la tête se situe sensiblement au voisinage du début du filet de la tige 4 présente une largeur radiale pouvant aller de 1 ,5 à 3 mm Cette portion 201 présente une élasticité axiale qui est telle que lorsqu'une pression axiale est exercée sur l'applicateur (par exemple, lors de la mise en appui de l'applicateur sur une surface à traiter), la partie elastiquement déformable 201 se referme légèrement sur la partie 200 (par un mouvement de repliement sensiblement autour de l'axe B), ce qui provoque un léger recul axial de l'extrémité libre des pattes 23 (en direction du fond de l'étui) La tige recule de la même manière, puis, par rappel élastique généré par la portion 201 , revient dans sa position initiale Typiquement, le recul peut aller deThe portion 201 which, when the head is mounted is located substantially in the vicinity of the start of the thread of the rod 4 has a radial width which can range from 1.5 to 3 mm. This portion 201 has an axial elasticity which is such that when a axial pressure is exerted on the applicator (for example, when the applicator rests on a surface to be treated), the elastically deformable part 201 closes slightly on the part 200 (by a folding movement substantially around axis B), which causes a slight axial retraction of the free end of the legs 23 (towards the bottom The rod moves back in the same way, then, by elastic return generated by the portion 201, returns to its initial position Typically, the recoil can range from
0,2 mm à 2 mm Cette élasticité dépend dans une large mesure du matériau utilisé (de préférence, un matériau thermoplastique), de la largeur radiale de la partie 201 , de l'angle entre la partie 200 et la partie 201 de préférence, voisin de 90°) Ainsi montée, la tige 4, et donc par voie de conséquence, l'applicateur 112, sont montés comme sur un ressort, ce qui confère à l'application une douceur remarquable Bien évidemment, les pattes 23 doivent être suffisamment rigides pour entraîner la tige à rencontre de la force de rappel exercée par le ressort 70.2 mm to 2 mm This elasticity depends to a large extent on the material used (preferably a thermoplastic material), on the radial width of the part 201, on the angle between the part 200 and the part 201 preferably, close to 90 °) Thus mounted, the rod 4, and therefore consequently, the applicator 112, are mounted as on a spring, which gives the application a remarkable softness Obviously, the legs 23 must be sufficiently rigid to drive the rod against the restoring force exerted by the spring 7
Par ailleurs, il est à noter que, avantageusement, si la pression exercée sur l'applicateur (par exemple, lors d'une chute) est trop forte, celle-ci engendre un repliement plus important de la partie 201 sur la partie 200, c'est à dire une fermeture plus importante de l'angle entre la partie 201 et la partie 200 Ce repliement plus important provoque un désengagement des pattes 23 par rapport à la tige, laquelle revient par rappel élastique, en position de repos contre le fond de l'étui Cette caractéristique avantageuse limite les risques d'endommagement accidentel de la pointe de l'applicateurIn addition, it should be noted that, advantageously, if the pressure exerted on the applicator (for example, during a fall) is too strong, this generates a greater folding of the part 201 on the part 200, that is to say a greater closure of the angle between the part 201 and the part 200 This greater folding causes a disengagement of the legs 23 relative to the rod, which returns by elastic return, in the rest position against the bottom of the case This advantageous characteristic limits the risks of accidental damage to the tip of the applicator
Lors du montage de la tête, ce qui correspond sensiblement à la position illustrée à ta figure 1 , la partie cylindrique 13 est insérée dans l'extrémité ouverte de l'étui 2 Ce faisant, les pattes 23 sont contraintes par la surface interne de l'étui, ce qui provoque leur mise en engagement avec le début du filetage de la tige 4 A ce stade il est a noter que l'applicateur n'est pas encore entraîné par la tige, l'entraînement ne se faisant que lors de la première utilisation en tournant la tête 10 par rapport à l'étui 2 Ainsi, chaque fois qu'une nouvelle tête 10 est montée sur l'étui, le positionnement de l'applicateur est constant En d'autres termes, le montage de la tête (et la mise en engagement des pattes d'entraînement 23 et de la tige 4) est une opération déconnectée de l'entraînement de l'applicateur en vue d'une applicationDuring mounting of the head, which corresponds substantially to the position illustrated in FIG. 1, the cylindrical part 13 is inserted into the open end of the case 2 In doing so, the tabs 23 are constrained by the internal surface of the case, which causes them to engage with the start of the thread of the rod 4 At this stage it should be noted that the applicator is not yet driven by the rod, the drive being done only during the first use by turning the head 10 relative to the case 2 Thus, each time a new head 10 is mounted on the case, the positioning of the applicator is constant In other words, the mounting of the head (and the engagement of the drive lugs 23 and of the rod 4) is an operation disconnected from the drive of the applicator for application
Les pattes 23 peuvent être réalisées en métal, en plastique, ou tout autre matériau offrant l'élasticité voulue Dans le mode de réalisation illustre, les pattes 23 sont de forme voisine de celle d'un L En réalité, leur forme est proche de celle d'un L en position contrainte (figures 1 et 2), et proche de celle d'un V en position non contrainte (figure 5B-5E) Selon un mode de réalisation avantageux, les pattes 23 sont obtenues de moulage d'un matériau thermoplastique (polyéthylène ou polypropylène), d'une seule pièce avec l'organe 21 qui les supporte.The legs 23 can be made of metal, plastic, or any other material offering the desired elasticity. In the illustrated embodiment, the legs 23 are of a shape close to that of an L In reality, their shape is close to that of an L in the constrained position (FIGS. 1 and 2), and close to that of a V in the unconstrained position (FIG. 5B-5E) According to an advantageous embodiment, the lugs 23 are obtained molding a thermoplastic material (polyethylene or polypropylene), in one piece with the member 21 which supports them.
Lorsque la tête est démontée de l'étui (par traction par exemple), les pattes 23 reviennent elastiquement en position écartée, se desengageant ainsi de la tige filetée 4 qui peut alors revenir en position de repos par action du ressort 7.When the head is removed from the case (by traction for example), the lugs 23 return elastically to the separated position, thereby disengaging from the threaded rod 4 which can then return to the rest position by action of the spring 7.
Dans le mode de réalisation des figures 5D et 5E, l'organe annulaire 21 porte également un anneau 50, relié à la partie 20 par deux bras 51 , 52, disposés à 90° par rapport aux pattes d'entraînement 23 Le diamètre interne de l'anneau est tel que la tige 4 et l'embout 17 puissent passer librement au travers, de manière à pouvoir venir en engagement avec les pattes 32 et 33 de la cupule 14 Toutefois, le diamètre interne de l'anneau 50 est tel que ce dernier forme, lorsque la pièce 21 est insérée dans la tête 10 (voir figure 5E), une butée annulaire qui empêche la mine 12 de sortir de la tête 10 par l'orifice délimité par la portion de plus large diamètre 15, la longueur des bras 51 , 52 étant choisie pour que, en position rentrée de la mine, l'anneau 50 soit situé au voisinage de l'extrémité libre des pattes 32, 33In the embodiment of FIGS. 5D and 5E, the annular member 21 also carries a ring 50, connected to the part 20 by two arms 51, 52, arranged at 90 ° relative to the drive lugs 23 The internal diameter of the ring is such that the rod 4 and the end piece 17 can pass freely through, so as to be able to come into engagement with the lugs 32 and 33 of the cup 14 However, the internal diameter of the ring 50 is such that the latter forms, when the part 21 is inserted into the head 10 (see FIG. 5E), an annular stop which prevents the lead 12 from coming out of the head 10 through the orifice delimited by the portion of larger diameter 15, the length arms 51, 52 being chosen so that, in the retracted position of the mine, the ring 50 is located in the vicinity of the free end of the legs 32, 33
Selon un autre mode de réalisation illustré à la figure 5F, l'entraînement de la tige est réalisé au moyen d'un écrou fileté fendu 100 porté par la tête Cet écrou fileté comprend deux demi coques 101 , 102 séparées par une fente 103, et dont la surface interne comporte au moins en son extrémité, un filetage 104 apte à coopérer avec le filetage de la tige. De la même manière que pour le mode de réalisation à pattes élastiques, l'écrou fendu est de forme coudée, ce qui confère au positionnement axial de l'applicateur, l'élasticité voulue L'engrenage de la tige se produit lorsque, les deux parties formant l'écrou fileté sont contraintes par une surface conique ménagée dans l'étui, le démontage de la tête libérant les deux demi coques filetées 101 , 102, produisant ainsi le désengagement de la tigeAccording to another embodiment illustrated in FIG. 5F, the rod is driven by means of a split threaded nut 100 carried by the head This threaded nut comprises two half shells 101, 102 separated by a slot 103, and the internal surface of which comprises at least at its end, a thread 104 capable of cooperating with the thread of the rod. In the same way as for the embodiment with elastic tabs, the split nut is bent in shape, which gives the axial positioning of the applicator the desired elasticity. The rod gear occurs when, both parts forming the threaded nut are constrained by a conical surface formed in the case, the disassembly of the head releasing the two threaded half shells 101, 102, thus producing the disengagement of the rod
La mine 12 est montée sur une cupule 14 que l'on va maintenant décrire plus en détail en référence à la figure 5A. Cette cupule comporte une jupe latérale 30 dont une extrémité est ouverte pour recevoir la mine et de forme généralement cylindrique adaptée à la forme de la mine. Le diamètre interne de la cupule est légèrement supérieur au diamètre de la mine, laquelle peut être mainter '<? dans la cupule par différents moyens appropriés, telles que des nervures rnénaç . sur la paroi interne de la cupule, ou par collage L'autre extrémité peut être fermée par une paroi transversale 31 Sur le fond 31 et à l'opposé de la jupe latérale 30, sont montées avantageusement deux pattes d'accrochage 32, 33 en un matériau, de préférence déformable elastiquement, de façon à, au repos, s'écarter de l'axe de la cupule 30, comme il apparaît à la figure 1 Selon une alternative, les pattes sont reliées au reste de la cupule par un mécanisme à charnières constitué par une zone de moindre épaisseur au niveau du fond 31. La forme des pattes d'accrochage est telle qu'elles peuvent enserrer l'embout 17 de la tige lorsque les pattes avancent dans le canal axialThe mine 12 is mounted on a cup 14 which will now be described in more detail with reference to FIG. 5A. This cup has a lateral skirt 30, one end of which is open to receive the lead and of generally cylindrical shape adapted to the shape of the lead. The internal diameter of the cup is slightly greater than the diameter of the mine, which can be maintained '<? into the cup by various suitable means, such as ribs. on the inner wall of the cup, or by gluing The other end can be closed by a transverse wall 31 On the bottom 31 and opposite the side skirt 30, are advantageously mounted two hooking lugs 32, 33 made of a material, of preferably elastically deformable, so that, at rest, deviate from the axis of the cup 30, as it appears in FIG. 1 According to an alternative, the legs are connected to the rest of the cup by a hinged mechanism constituted by a zone of reduced thickness at the bottom 31. The shape of the attachment lugs is such that they can grip the end piece 17 of the rod when the lugs advance in the axial channel
11 Selon un mode de réalisation préféré, chacune des pattes d'accrochage définit sensiblement une forme de L11 According to a preferred embodiment, each of the attachment tabs substantially defines an L-shape
Selon un autre mode de réalisation, le fond de la cupule est ouvert, au moins en partie, de manière à pouvoir couler la mine avant montage sur le dispositif, au travers du fond de la cupule.According to another embodiment, the bottom of the cup is open, at least in part, so as to be able to sink the lead before mounting on the device, through the bottom of the cup.
Par ailleurs, même si l'accrochage de la mine est un mode de réalisation préféré de l'invention, de manière à permettre à la fois la sortie et la rentrée de la mine dans la tête, cette fonction n'est cependant pas indispensable En effet, selon un mode de réalisation possible, la tige ne comporte pas de moyens pour l'accrochage de la cupule de sorte que la mine n'est entraînée que dans le sens de la sortie, et ce jusqu'à son utilisation complète Dans ces conditions, le démontage de la tête, par exemple par traction, ne provoque que la libération de la tige par rapport a la tête et la remontée de la tige contre le fond de l'étui, sous l'effet de la force de rappel du ressort Dans cette configuration, des moyens doivent être prévus pour retenir la mine à l'intérieur du canal A titre d'exemple, on peut prévoir des crans sur la surface interne du canal axial, aptes à coopérer avec un ou plusieurs organes correspondants (ergots ou nervures) prévus sur la surface externe de la cupule, le franchissement des crans s'effectuant en force, sous l'effet de la poussée de la tige 4 D'autres arrangements encore peuvent être prévus pour maintenir la mine à l'intérieur du canalFurthermore, even if the attachment of the mine is a preferred embodiment of the invention, so as to allow both the exit and the re-entry of the mine into the head, this function is not however essential. Indeed, according to a possible embodiment, the rod does not include means for hooking the cup so that the mine is driven only in the direction of exit, and this until its complete use In these conditions, disassembly of the head, for example by traction, only causes the release of the rod relative to the head and the ascent of the rod against the bottom of the case, under the effect of the restoring force of the spring In this configuration, means must be provided for retaining the mine inside the channel. For example, it is possible to provide notches on the internal surface of the axial channel, capable of cooperating with one or more corresponding members (pins or ribs) provided on the surface external of the cup, the crossing of the notches being effected by force, under the effect of the pushing of the rod 4 Still other arrangements can be provided for keeping the mine inside the channel
Le fonctionnement du dispositif selon l'invention va maintenant être expliqué plus en détail en référence aux figures 1 à 3 et 5C A la figure 5C, la tête est démontée de l'étui (par exemple, par traction) Ainsi qu'il apparaît, la mine est remontée à l'intérieur du canal axial de la tête 10 Les pattes d'accrochage 32, 33 sont en regard de la portion tronconique 16, et maintenues en appui contre les parois de la partie tronconique par effet de rappel élastique Les pattes d'entraînement 23, sont en position de repos, c'est à dire écartées de l'axe de la tête, le sommet du V qu'elles définissent émergeant de la partie 13, au travers des lumières 24 Ainsi qu'il apparaît à la figure 3, dans l'étui 2, la tige 4 portant le filetage, est maintenue en rappel contre le fond 3 de l'étui grâce au ressort 7The operation of the device according to the invention will now be explained in more detail with reference to FIGS. 1 to 3 and 5C In FIG. 5C, the head is removed from the case (for example, by traction) As it appears, the mine is raised inside the axial channel of the head 10 The attachment tabs 32, 33 are opposite the frustoconical portion 16, and held in abutment against the walls of the part frustoconical by elastic return effect The drive lugs 23 are in the rest position, that is to say spaced from the axis of the head, the top of the V which they define emerging from the part 13, through the lights 24 As it appears in FIG. 3, in the case 2, the rod 4 carrying the thread, is held in abseiling against the bottom 3 of the case thanks to the spring 7
Dans la position de la figure 1 , la tête 10 est montée sur l'étui 2 les pattes d'entraînement 23, contraintes par les parois de l'étui 2 sont en engagement avec le début du filetage de la tige 4 L'embout 17 de la tige 4 est situe entre les pattes d'accrochage 32, 33 de la cupule, lesquelles pattes sont au niveau de la zone tronconique du canal ménage à l'intérieur de la tête, ce qui autorise les pattes à s'écarter vers l'extérieur, sensiblement contre la surface tronconique, empêchant ainsi la mine de redescendre dans le canal II est a noter, qu'en position telle que représentée à la figure 1 , la tête est maintenue sur l'étui de manière élastique au moyen du ressort de rappel, ce qui permet de limiter le serrage tête/étui et d'adoucir la rotation de la tête par rapport au corps du dispositif, chaque fonction étant séparéeIn the position of Figure 1, the head 10 is mounted on the case 2 the drive tabs 23, constrained by the walls of the case 2 are in engagement with the start of the threading of the rod 4 The end piece 17 of the rod 4 is located between the hooking tabs 32, 33 of the cup, which tabs are at the frustoconical zone of the household channel inside the head, which allows the tabs to move towards the exterior, substantially against the frusto-conical surface, thus preventing the mine from going back down into the channel II should be noted, that in position as represented in FIG. 1, the head is held on the case in an elastic manner by means of the spring recall, which limits the head / case tightening and soften the rotation of the head relative to the body of the device, each function being separate
Une rotation de la tête par rapport à l'étui provoque une avancée de la tige 4 entre les pattes 32, 33 de la cupule 14 (figure 2) L'embout 17 pousse alors la mine dans le canal, ce qui provoque une fermeture des pattes 32, 33 sur l'embout, solidarisant ainsi la tige de la cupule. L'extrémité de la mine peut ainsi être sortie de ia tête en vue de l'application du produit Une fois l'application terminée, une rotation en sens inverse de la tête 10 par rapport à l'étui 2 provoque un recul de la mine, jusqu'à ce que les pattes 32, 32 ne soient plus maintenues à l'intérieur du canal, c'est a dire jusqu'à ce qu'elles soient situées en regard de la partie tronconique 16 A ce moment, la mine 12 n'est plus solidaire de la tige 4A rotation of the head relative to the case causes an advance of the rod 4 between the legs 32, 33 of the cup 14 (Figure 2) The tip 17 then pushes the mine into the channel, which causes the closure of the tabs 32, 33 on the end piece, thus joining the stem of the cup. The end of the mine can thus be removed from the head for the application of the product. Once the application is complete, a rotation in the opposite direction of the head 10 relative to the case 2 causes the mine to retreat. , until the legs 32, 32 are no longer held inside the channel, that is to say until they are located opposite the frustoconical part 16 At this time, the mine 12 is no longer attached to the rod 4
Ainsi, si en cours d'utilisation, la tête est démontée de l'étui (par traction de la tête par rapport à l'étui), cela provoque une remontée de la mine 12 à l'intérieur du canal 11 , l'écartement des pattes d'entraînement 23 par rapport au filetage de la tige, le rappel de la tige contre le fond 3 de l'étui 2 sous l'action du ressort de rappel 7, la désolidaπsation de la tige 4 par rapport à la mine lorsque celle-ci est complètement rentrée dans le canal (11 ), la libération de la tête par rapport au corps de l'etui De ce fait, en cours d'utilisation, il est très facile de changer de produit, par exemple de teinte, par simple remplacement de le tête du dispositif Les figures 4C et 4D illustrent différentes formes du dispositif selon la présente invention Dans le mode de réalisation de la figure 4C, la section transversale est de forme ovale, dans celui de la figure 4D la section transversale est sensiblement carrée, ce qui était difficilement réalisable avec les dispositifs conventionnels tels que discutes dans le préambule de la présente description II est évident que d'autres formes encore peuvent être utilisées (triangulaire, circulaire, carrée, polygonale, ovale, losange) Les dimensions de la section transversale du dispositif selon l'invention sont choisies en fonction de la nature du produit à appliquer (rouge à lèvres, teinte, ombre à paupières, etc )Thus, if in use, the head is removed from the case (by pulling the head relative to the case), this causes the mine 12 to rise inside the channel 11, the spacing drive lugs 23 relative to the thread of the rod, the return of the rod against the bottom 3 of the case 2 under the action of the return spring 7, the separation of the rod 4 from the mine when the latter is completely retracted into the channel (11), the release of the head relative to the body of the case. Therefore, during use, it is very easy to change the product, for example of color, by simply replacing the device head Figures 4C and 4D illustrate different forms of the device according to the present invention In the embodiment of Figure 4C, the cross section is oval, in that of Figure 4D the cross section is substantially square, which was difficult to achieve with conventional devices as discussed in the preamble to the present description It is obvious that still other shapes can be used (triangular, circular, square, polygonal, oval, rhombus) The dimensions of the cross section of the device according to the invention are chosen according to the nature of the product to be applied (lipstick, shade, eye shadow, etc.)
On peut prévoir un flocage, soit sur l'applicateur, soit sur les parois internes du canal axial de la tête, de manière à limiter le jeu de l'applicateur dans la tête du dispositif Un tel flocage peut également être disposé sur la surface extérieure de l'extrémité de la têteFlocking can be provided either on the applicator or on the internal walls of the axial channel of the head, so as to limit the play of the applicator in the head of the device. Such flocking can also be arranged on the external surface. from the end of the head
Avantageusement encore, le dispositif comporte un bouchon de protection qui pourra être monté sur la tête (par vissage ou claquage par exemple) pour protéger la mineAdvantageously also, the device comprises a protective plug which can be mounted on the head (by screwing or snapping for example) to protect the mine
A la figure 6 à laquelle il est maintenant fait référence, le dispositif selon l'invention est utilise pour un applicateur 12 sous forme d'un raisin de rouge a lèvres De la même manière que pour les autres modes de réalisation, le raisin de rouge a lèvres est monté dans une cupule 14 Des moyens 62 sont prévus sous la cupule et/ou sur la paroi interne du canal axial 11 , de manière à faire étaπchéité et/ou à former une butée pour empêcher le raisin de sortir de la tête au travers de l'orifice délimité par la portion de plus grand diamètre 15 Dans ce dernier cas, le raisin de rouge à lèvres ne peut être monte dans la tête que par l'orifice de sortie délimité par le bord libre 64 de la tête Dans ce mode de réalisation, et étant donné le diamètre plus important de l'applicateur et de la cupule 14, une rainure annulaire 63 est prévue pour permettre un dégagement suffisant des pattes 32 et 33, lorsque l'applicateur est en position rentrée dans ta tête 10, telle que représentée à la figure 6, et permettre de désolidariser l'applicateur 12 deIn FIG. 6 to which reference is now made, the device according to the invention is used for an applicator 12 in the form of a lipstick grape. In the same way as for the other embodiments, the red grape a lip is mounted in a cup 14 Means 62 are provided under the cup and / or on the internal wall of the axial channel 11, so as to seal and / or form a stop to prevent the grapes from coming out of the head at through the orifice delimited by the portion of larger diameter 15 In the latter case, the lipstick grape can be mounted in the head only by the outlet orifice delimited by the free edge 64 of the head In this embodiment, and given the larger diameter of the applicator and of the cup 14, an annular groove 63 is provided to allow sufficient clearance of the legs 32 and 33, when the applicator is in the retracted position in your head 10 , as shown in Figure 6, and allow to separate the applicator 12 from
Un capot 60 est monté par claquage ou par vissage sur la tête 10 Un bloc de mousse 61 est disposé dans le fond du capot de manière à faire étancheité en position fermée du capot sur la tête, la face du bloc de mousse destinée à venir en appui sur le bord libre 64 de la tête 10 étant étanche au (ou aux) solvant(s) contenus dans la formulation des rouges à lèvres. Le bloc de mousse est choisi pour qu'il soit en appui étanche sur le bord libre 64 de la tête, en tout point dudit bord, et ce quelque soit le profil du bord (en biseau ou droit). Un tel dispositif est particulièrement adapté aux formulation à solvants fortement volatils. Alternativement, Pétanchéité du bord libre 64 est assurée par une jupe étanche obtenue de moulage avec le capot 60A cover 60 is mounted by snap-fastening or by screwing on the head 10 A block of foam 61 is arranged in the bottom of the cover so as to provide sealing in the closed position of the cover on the head, the face of the block of foam intended to come to bear on the free edge 64 of the head 10 being impermeable to the solvent (s) contained in the formulation of the lipsticks. The foam block is chosen so that it is in leaktight support on the free edge 64 of the head, at any point of said edge, regardless of the edge profile (bevel or straight). Such a device is particularly suitable for formulation with highly volatile solvents. Alternatively, the tightness of the free edge 64 is ensured by a tight skirt obtained from molding with the cover 60
