ARRIERE-PLAN DE L'INVENTIONBACKGROUND OF THE INVENTION

On connaît du document DE 42 01 064 A des dispositifs applicateurs de produit comportant :

  • un tube protecteur s'étendant selon une direction longitudinale entre des première et deuxième extrémités, la deuxième extrémité étant ouverte,
  • une cartouche interchangeable contenue dans le tube protecteur, cette cartouche comportant une cupule et un bâton de produit, ledit bâton de produit s'étendant selon ladite direction longitudinale entre une extrémité proximale engagée à l'intérieur de la cupule et une extrémité distale éloignée de ladite cupule,
  • un mécanisme de manoeuvre adapté pour déplacer le bâton de produit dans le tube protecteur selon la direction longitudinale de façon à pouvoir faire sortir au moins une partie du bâton de produit par la deuxième extrémité du tube protecteur, ledit mécanisme de manoeuvre comportant un coulisseau sur lequel la cupule est fixée de façon amovible.
Document is known DE 42 01 064 A product applicator devices comprising:
  • a protective tube extending in a longitudinal direction between first and second ends, the second end being open,
  • an interchangeable cartridge contained in the protective tube, which cartridge comprises a cup and a product stick, said product stick extending in said longitudinal direction between a proximal end engaged inside the cup and a distal end remote from said cup,
  • an operating mechanism adapted to move the product stick in the protective tube in the longitudinal direction so as to be able to remove at least a portion of the product stick by the second end of the protective tube, said actuating mechanism comprising a slide on which the cup is removably attached.

Le document GB-A-655 718 décrit un exemple d'un tel dispositif applicateur, destiné notamment aux rouges à lèvres. Dans ce dispositif connu, la cupule de la cartouche comporte sur son bord libre, des pattes radiales saillantes qui sont adaptées pour être engagées dans des gorges ménagées à l'extrémité ouverte d'un tube de recharge. Le tube de recharge contient la cartouche avant sa mise en place dans le dispositif applicateur, et permet également d'enlever la cartouche usagée du dispositif applicateur.The document GB-A-655,718 describes an example of such an applicator device, intended in particular for lipsticks. In this known device, the cup of the cartridge has on its free edge, projecting radial tabs which are adapted to be engaged in grooves formed at the open end of a refill tube. The refill tube contains the cartridge prior to placement in the applicator device, and also removes the used cartridge from the applicator device.

Ce dispositif connu présente notamment l'inconvénient que les pattes radiales de la cupule sont saillantes. De ce fait, ces pattes radiales imposent des contraintes dans la conception du dispositif applicateur et en limitent la compacité. De plus, lesdites pattes radiales peuvent éventuellement gêner l'utilisateur lors de l'application du produit, notamment lorsque le bâton de produit est en fin de vie.This known device presents in particular the disadvantage that the radial tabs of the cup are protruding. As a result, these radial tabs impose constraints in the design of the applicator device and limit its compactness. In addition, said radial tabs may possibly interfere with the user during the application of the product, especially when the product stick is at the end of its life.

DESCRIPTION DETAILLEEDETAILED DESCRIPTION

Sur les différentes figures, les mêmes références désignent des éléments identiques ou similaires.In the different figures, the same references designate identical or similar elements.

A. Première forme de réalisation de l'invention A. First embodiment of the invention a) Dispositif applicateur a) Applicator device

Comme on peut le voir sur les figures 1 à 4, le dispositif applicateur 1 comporte un tube protecteur 2 qui s'étend selon une direction longitudinale X entre des première et deuxième extrémités 3, 4. Plus précisément, le tube protecteur 2 peut notamment présenter une forme générale cylindrique de révolution d'axe central X. La deuxième extrémité 4 est ouverte.As can be seen on the Figures 1 to 4 , the applicator device 1 comprises a protective tube 2 which extends in a longitudinal direction X between first and second ends 3, 4. More specifically, the protective tube 2 may in particular have a generally cylindrical shape of central axis revolution X The second end 4 is open.

Ce tube protecteur 2 peut par exemple être réalisé en matière plastique et peut éventuellement être recouvert extérieurement, dans ses parties visibles (c'est-à-dire dans ses parties proches de la deuxième extrémité 4) par une virole métallique 5 décorative.This protective tube 2 may for example be made of plastic material and may optionally be externally covered, in its visible parts (that is to say in its parts near the second end 4) by a decorative metal shell 5.

Le tube protecteur 2 contient une cartouche interchangeable 6 qui comporte :

  • une cupule 7 réalisée par exemple en matière plastique, et
  • un bâton 8 de produit, ici un raisin de rouge à lèvres à titre d'exemple pour l'ensemble des figures.
The protective tube 2 contains an interchangeable cartridge 6 which comprises:
  • a cup 7 made for example of plastic, and
  • a stick 8 of product, here a grape of lipstick as an example for all the figures.

Le bâton 8 de produit est généralement réalisé dans un produit solide ou pâteux pouvant être conformé de manière stable dans le temps et à température ambiante sous forme de bâton ou de stick. Ce type de produit solide ou pâteux comprend généralement une cire ou un mélange de cires et se dépose lors de son utilisation sur une surface par contact. On entend aussi par produit solide ou pâteux, un produit susceptible d'être pénétré par un objet rigide sans pour autant perdre son intégrité lorsqu'il est conformé sous une forme donnée, telle qu'un bâton.The stick 8 of product is generally made in a solid or pasty product that can be stably shaped in time and at room temperature in the form of a stick or stick. This type of solid or pasty product generally comprises a wax or a mixture of waxes and is deposited during its use on a surface by contact. We also mean by solid or pasty product, a product capable of being penetrated by a rigid object without losing its integrity when it is shaped in a given form, such as a stick.

Le bâton 8 de produit s'étend selon la direction longitudinale X entre une extrémité proximale 9 solidaire de la cupule 7 et une extrémité distale 10 proche de la deuxième extrémité 4 du tube protecteur et adapté pour sortir du tube protecteur 2 par cette deuxième extrémité 4.The stick 8 of product extends in the longitudinal direction X between a proximal end 9 secured to the cup 7 and a distal end 10 close to the second end 4 of the protective tube and adapted to exit the protective tube 2 by the second end 4 .

Dans l'exemple représenté sur les dessins, la cupule 7 définit un certain volume intérieur dans lequel est engagée l'extrémité proximale 9 du bâton de produit. Plus particulièrement, dans l'exemple considéré, la cupule 7 peut présenter un fond 11 et une paroi latérale 12 ayant par exemple une forme générale cylindrique de révolution centrée sur l'axe X. Cette paroi latérale 12 s'étend depuis le fond 11 jusqu'à une extrémité libre 13, en direction de l'extrémité distale 10 du bâton de produit.In the example shown in the drawings, the cup 7 defines a certain internal volume in which is engaged the proximal end 9 of the product stick. More particularly, in the example considered, the cup 7 may have a bottom 11 and a side wall 12 having for example a generally cylindrical shape of revolution centered on the axis X. This side wall 12 extends from the bottom 11 to the bottom. at a free end 13, towards the distal end 10 of the product stick.

Selon l'invention, pour faciliter l'extraction de la cartouche 6 de produit lorsque le bâton 8 de produit est usé, la cupule 7 est dotée d'un rebord intérieur qui fait saillie radialement vers l'intérieur et qui est recouvert par le bâton 8 de produit vers l'intérieur de ladite cupule mais qui peut coopérer avec un organe d'extraction externe que l'on fait pénétrer dans le bâton de produit de façon à pouvoir extraire la cartouche 6 usagée et la remplacer par une cartouche neuve.According to the invention, to facilitate the extraction of the cartridge 6 of product when the stick 8 of product is worn, the cup 7 is provided with an inner rim which projects radially inward and which is covered by the stick 8 of product in the interior of said cup but which can cooperate with an external extraction member that is made to penetrate into the product stick so as to extract the used cartridge 6 and replace it with a new cartridge.

Dans la première forme de réalisation de l'invention, le rebord intérieur susmentionné de la cupule est constitué par une nervure annulaire 14 ménagée à l'intérieur de la paroi latérale 12, au voisinage de l'extrémité libre 13. Comme représenté plus en détail sur la figure 2A, la nervure 14 peut le cas échéant présenter une face inclinée 15 et un épaulement 16, la face inclinée s'étendant en biais vers le fond 11 et radialement vers l'intérieur jusqu'à l'épaulement 16, lequel est orienté face au fond 11, sensiblement perpendiculairement à l'axe central X.In the first embodiment of the invention, the abovementioned inner rim of the cup is constituted by an annular rib 14 formed inside the side wall 12, in the vicinity of the free end 13. As shown in more detail on the Figure 2A , the rib 14 may optionally have an inclined face 15 and a shoulder 16, the inclined face extending obliquely towards the bottom 11 and radially inwardly to the shoulder 16, which is oriented towards the bottom 11, substantially perpendicular to the central axis X.

Comme représenté sur les figures 1 et 2, le dispositif applicateur 1 comporte en outre un mécanisme de manoeuvre 17 adapté pour déplacer le bâton 8 de produit entre :

  • une position rétractée (figure 2) où ledit bâton 8 est entièrement contenu dans le tube protecteur 2,
  • et une position d'utilisation (figure 1) où le bâton 8 fait saillie hors de la deuxième extrémité 4 du tube protecteur 2.
As shown on figures 1 and 2 , the applicator device 1 further comprises an operating mechanism 17 adapted to move the stick 8 of product between:
  • a retracted position ( figure 2 ) where said stick 8 is entirely contained in the protective tube 2,
  • and a position of use ( figure 1 ) where the stick 8 protrudes out of the second end 4 of the protective tube 2.

Dans l'exemple représenté sur les dessins, le mécanisme de manoeuvre 17 inclut une base 18 qui forme la partie inférieure du dispositif applicateur. Cette base 18 comporte un fond 19 permettant de poser le dispositif applicateur 1 sur une surface horizontale, et une paroi latérale 20 qui s'étend selon l'axe central X à partir du fond 19 en entourant la partie inférieure du tube protecteur 2, au voisinage de la première extrémité 3 de ce tube protecteur.In the example shown in the drawings, the operating mechanism 17 includes a base 18 which forms the lower portion of the applicator device. This base 18 comprises a bottom 19 for laying the applicator device 1 on a horizontal surface, and a side wall 20 which extends along the central axis X from the bottom 19 surrounding the lower part of the protective tube 2, at the near the first end 3 of this protective tube.

La partie supérieure de la paroi latérale 20 de la base 18 peut éventuellement comporter une portion amincie 21 sur laquelle peut venir s'emboîter un capot protecteur 22 (figure 1) adapté pour recouvrir le tube protecteur 2 lorsque le bâton 8 de produit est en position rétractée.The upper part of the side wall 20 of the base 18 may optionally comprise a thinned portion 21 on which a protective cover 22 may be fitted ( figure 1 ) adapted to cover the protective tube 2 when the stick 8 of product is in the retracted position.

La base 18 peut être montée rotative par rapport au tube protecteur 2 autour de l'axe central X, de façon à commander le coulissement du bâton 8 de produit entre sa position rétractée et sa position d'utilisation. Comme représenté sur les figures 2 et 3, le mécanisme de manoeuvre 17 peut éventuellement comporter :

  • une vis 23 s'étendant longitudinalement selon l'axe X et solidaire d'un coulisseau 24 qui coulisse selon l'axe X à l'intérieur du tube protecteur 2,
  • et un écrou 25 qui est vissé sur la vis 23 et qui est solidarisé en rotation avec la base 18.
The base 18 may be rotatably mounted relative to the protective tube 2 about the central axis X, so as to control the sliding of the stick 8 of product between its retracted position and its position of use. As shown on figures 2 and 3 , the operating mechanism 17 may optionally comprise:
  • a screw 23 extending longitudinally along the axis X and integral with a slide 24 which slides along the axis X inside the protective tube 2,
  • and a nut 25 which is screwed onto the screw 23 and which is secured in rotation with the base 18.

Dans l'exemple particulier représenté sur les figures 2 ou 3, la vis 23 peut être réalisée d'une seule pièce en matière plastique avec le coulisseau 24, et l'écrou 25 peut être lui-même réalisé en matière plastique.In the particular example shown on the figures 2 or 3 , the screw 23 can be made in one piece of plastic material with the slider 24, and the nut 25 may itself be made of plastic.

La vis 23 peut se présenter notamment sous la forme d'une tige creuse présentant :

  • deux faces latérales planes 26 opposées (voir les figures 2 et 4) qui s'étendent parallèlement l'une à l'autre et parallèlement à l'axe X, et
  • deux faces latérales 27 en forme de portions de cylindre centrées sur l'axe X comme visible sur la figure 3, qui sont diamétralement opposées l'une à l'autre et se raccordent aux faces latérales planes 26. Les faces latérales 27 en forme de portions de cylindre sont dotées d'un filetage 28 externe qui est en prise avec un filetage interne 29 de l'écrou 25 (voir les figures 3 et 4).
The screw 23 can be in particular in the form a hollow stem with:
  • two opposing flat side faces 26 (see figures 2 and 4 ) which extend parallel to each other and parallel to the X axis, and
  • two lateral faces 27 in the form of cylinder portions centered on the X axis as visible on the figure 3 , which are diametrically opposed to each other and are connected to the flat side faces 26. The side faces 27 in the form of cylinder portions are provided with an external thread 28 which is engaged with an internal thread 29 of the cylinder. 'nut 25 (see the figures 3 and 4 ).

La vis 23 s'étend depuis le coulisseau 24 vers le fond 19 de la base 20 en traversant un évidement 30 ménagé dans une paroi transversale 31 qui peut être formée d'une seule pièce avec le tube protecteur 2, en matière plastique, et qui s'étend radialement vers l'intérieur de ce tube protecteur à une position intermédiaire entre les première et deuxième extrémités 3, 4 dudit tube protecteur. Comme représenté sur la figure 4, l'évidement 30 peut présenter une forme sensiblement complémentaire de la forme extérieure de la vis 23, de façon à empêcher une rotation de la vis 23 autour de l'axe X par effet d'emboîtement (les deux faces latérales planes 26 de la vis 23 sont en contact glissant avec deux bords rectilignes opposés de l'évidement 30), tout en permettant à la vis 23 de se déplacer en translation selon l'axe X avec le coulisseau 24 à l'intérieur du tube protecteur 2.The screw 23 extends from the slider 24 towards the bottom 19 of the base 20 through a recess 30 formed in a transverse wall 31 which can be formed in one piece with the protective tube 2, made of plastic, and which extends radially inwardly of this protective tube at an intermediate position between the first and second ends 3, 4 of said protective tube. As shown on the figure 4 , the recess 30 may have a shape substantially complementary to the outer shape of the screw 23, so as to prevent a rotation of the screw 23 about the axis X by interlocking effect (the two flat lateral faces 26 of the screws 23 are in sliding contact with two opposite straight edges of the recess 30), while allowing the screw 23 to move in translation along the X axis with the slider 24 inside the protective tube 2.

Le mouvement de la vis 23 à l'intérieur du tube protecteur 2 est limité :

  • vers le bas (c'est-à-dire vers la base 18), par butée du coulisseau 24 sur la paroi transversale 31,
  • et vers le haut (c'est-à-dire vers la deuxième extrémité du tube protecteur 2), par exemple par appui de deux pattes élastiques 32 contre la paroi transversale 30.
The movement of the screw 23 inside the protective tube 2 is limited:
  • downwards (that is to say towards the base 18), by abutment of the slider 24 on the transverse wall 31,
  • and upwards (that is to say towards the second end of the protective tube 2), for example by pressing two elastic tabs 32 against the transverse wall 30.

Ces pattes élastiques 32 peuvent par exemple être moulées d'une seule pièce avec la vis 23, au voisinage de l'extrémité libre 33 de cette vis 23, et lesdites pattes élastiques 32 peuvent être adaptées pour traverser l'évidement 30 de la paroi transversale 31 par déformation élastique lors de la première mise en place de la vis 23 dans le tube protecteur 2. A cet effet, les pattes élastiques 32 sont déformables radialement vers l'intérieur et peuvent présenter le cas échéant chacune une surface de came 32a s'étendant en biais vers le haut et radialement vers l'extérieur depuis l'une des parois latérales planes 26 de la vis, et une face supérieure d'arrêt 32b s'étendant sensiblement perpendiculairement à l'axe X (voir la figure 2).These elastic tabs 32 may for example be molded in one piece with the screw 23, in the vicinity of the free end 33 of this screw 23, and said elastic tabs 32 may be adapted to traverse the recess 30 of the transverse wall 31 by elastic deformation during the first introduction of the screw 23 in the protective tube 2. For this purpose, the resilient tabs 32 are deformable radially inwards and may present if necessary each having a cam surface 32a extending upwardly and radially outwardly from one of the flat sidewalls 26 of the screw, and an upper stop face 32b extending substantially perpendicular to the axis X (see the figure 2 ).

Le coulisseau 24, quant à lui, peut par exemple se présenter sous la forme d'un simple plateau s'étendant perpendiculairement à l'axe X, comme représenté, ou encore sous la forme d'une coupelle ouverte vers la deuxième extrémité 4 du tube protecteur, ou sous toute autre forme. Ce coulisseau 24 est doté, dans l'exemple considéré ici, d'une ouverture centrale 34 dans laquelle peut se clipser un téton élastique 35, formé d'une seule pièce sous le fond 11 de la cupule 7 susmentionnée. Ce téton élastique 35 peut par exemple présenter une paroi latérale 36, ayant une symétrie de révolution sensiblement cylindrique centrée sur l'axe X, dotée à son extrémité libre d'une lèvre 37 faisant saillie radialement vers l'extérieur et adaptée pour retenir la cupule 7 de façon amovible sur le coulisseau 24, par clipsage dans l'ouverture 34.The slider 24, for its part, may for example be in the form of a simple plate extending perpendicular to the X axis, as shown, or in the form of a cup open towards the second end 4 of the protective tube, or in any other form. This slider 24 is provided, in the example considered here, with a central opening 34 in which can be clipped an elastic stud 35, formed in one piece under the bottom 11 of the aforementioned cup 7. This elastic stud 35 may for example have a side wall 36, having a substantially cylindrical rotational symmetry centered on the X axis, provided at its free end with a lip 37 projecting radially outwardly and adapted to retain the cup 7 removably on the slide 24, by clipping into the opening 34.

Enfin, l'écrou 25 susmentionné peut présenter par exemple une partie inférieure 38, cannelée ou non qui est emboîtée à force dans une partie interne complémentaire ménagée dans la base 20. Cette partie inférieure 38 présente une forme annulaire et entoure la vis 23, sans interférer avec cette vis. Ladite partie inférieure 38 se prolonge vers la paroi transversale 30 du tube protecteur par une partie intermédiaire 39 annulaire qui est elle-même non filetée, puis par une partie supérieure 40 qui est dotée du filetage intérieur 29 susmentionné.Finally, the above-mentioned nut 25 may for example have a lower part 38, grooved or not, which is force fitted into a complementary internal part formed in the base 20. This lower part 38 has an annular shape and surrounds the screw 23, without interfere with this screw. Said lower portion 38 extends to the transverse wall 30 of the protective tube by an annular intermediate portion 39 which is itself unthreaded, then by an upper portion 40 which is provided with the aforementioned internal thread 29.

Grâce au mécanisme de manoeuvre 17, une rotation de la base 20 par rapport au tube protecteur 2 autour de l'axe X se traduit par un coulissement du coulisseau 24 et de la cartouche 6 de produit de façon à faire sortir ou au contraire à rentrer le bâton 8 de produit par rapport au tube protecteur 2.Thanks to the operating mechanism 17, a rotation of the base 20 relative to the protective tube 2 about the X axis results in a sliding of the slide 24 and the cartridge 6 of product to make out or on the contrary to return the stick 8 of product relative to the protective tube 2.

Bien entendu, le mécanisme de manoeuvre particulier qui est décrit ci-dessus n'est donné qu'à titre d'exemple, d'autres mécanismes de manoeuvre étant utilisables pour la commande du déplacement d'un bâton de produit, notamment des mécanismes de manoeuvre faisant appel à des rainures ménagées dans des pièces disposées concentriquement au bâton 8 de produit, comme cela est bien connu dans l'état de l'art.Of course, the particular operating mechanism described above is only given by way of example, other operating mechanisms being usable for controlling the movement of a stick of product, particularly operation using grooves in rooms arranged concentrically to stick 8 of product, as is well known in the state of the art.

Les figures 5 à 8 représentent un exemple de recharge 41 permettant de changer la cartouche 6 de produit du dispositif d'applicateur 1 décrit précédemment.The Figures 5 to 8 represent an example of recharge 41 for changing the product cartridge 6 of the applicator device 1 described above.

Cette recharge 41 comporte un boîtier 42, réalisé par exemple en matière plastique, qui délimite un logement de recharge 43, contenant une cartouche neuve 6 de produit, identique à la cartouche 6 décrite précédemment dans le cadre du dispositif applicateur 1 (voir la figure 6).This refill 41 comprises a housing 42, made for example of plastic, which delimits a refill housing 43, containing a new cartridge 6 of product, identical to the cartridge 6 previously described in the context of the applicator device 1 (see FIG. figure 6 ).

Le boîtier 42 peut éventuellement présenter une forme extérieure sensiblement parallélépipédique, et peut présenter une forme allongée s'étendant longitudinalement selon un axe central X'. Le logement de recharge 43 peut présenter une forme cylindrique de révolution centrée sur l'axe X'.The housing 42 may optionally have a substantially parallelepiped external shape, and may have an elongate shape extending longitudinally along a central axis X '. The charging housing 43 may have a cylindrical shape of revolution centered on the axis X '.

Le boîtier 42 peut présenter une paroi latérale interne annulaire 44 qui délimite le logement de recharge 43, lequel logement de recharge s'étend selon l'axe central X' entre une première extrémité 45 et une deuxième extrémité 46. La première extrémité 45 du logement de recharge 43 peut-être obturée par exemple par une cloison transversale 47 formée d'une seule pièce avec la paroi latérale 44 du boîtier de la recharge. La deuxième extrémité 46 du logement de recharge est ouverte et peut éventuellement être obturée temporairement par une membrane protectrice amovible 48 qui peut être par exemple thermo scellée ou collée sur la face d'extrémité de la paroi latérale 43 (voir les figures 6 et 8).The housing 42 may have an annular inner side wall 44 which delimits the charging housing 43, which recharging housing extends along the central axis X 'between a first end 45 and a second end 46. The first end 45 of the housing recharge 43 can be closed for example by a transverse partition 47 formed integrally with the side wall 44 of the housing of the refill. The second end 46 of the charging compartment is open and may optionally be closed temporarily by a removable protective membrane 48 which may for example be thermally sealed or bonded to the end face of the wall Lateral 43 (see figures 6 and 8 ).

Comme représenté sur le figure 6, la cartouche neuve 6 de produit est disposée dans le logement de recharge 43 avec le fond 11 de sa cupule proche de la deuxième extrémité 46 du logement de recharge et avec l'extrémité distale 10 de son bâton de produit proche de la première extrémité 45 du logement de recharge.As represented on the figure 6 , the new product cartridge 6 is disposed in the charging housing 43 with the bottom 11 of its cup near the second end 46 of the refill housing and with the distal end 10 of its product stick near the first end 45 recharge housing.

La cartouche 6 est maintenue en place dans le logement de recharge par emboîtement de sa cupule 7 à la deuxième extrémité 46 du logement de recharge, ledit logement de recharge comportant un épaulement 49 qui est orienté vers ladite deuxième extrémité 46 pour pouvoir être en appui contre la cupule selon la direction axiale X'. L'épaulement 49 peut ainsi exercer une poussée sur ladite cupule 7 selon la direction axiale X' lors de la mise en place de la cartouche neuve 6 sur un dispositif applicateur 1 après extraction d'une cartouche usagée 6 dudit dispositif applicateur, comme il sera expliqué ci-après.The cartridge 6 is held in place in the refill housing by interlocking its cup 7 at the second end 46 of the refill housing, said refill housing having a shoulder 49 which is oriented towards said second end 46 to be able to bear against the cup in the axial direction X '. The shoulder 49 can thus exert a thrust on said cup 7 in the axial direction X 'during the introduction of the new cartridge 6 on an applicator device 1 after extraction of a used cartridge 6 of said applicator device, as it will be explained below.

Plus particulièrement, dans l'exemple considéré ici, le logement de recharge 43 comprend un organe de maintient de la cupule, à savoir une paroi annulaire intérieure 50, de forme générale sensiblement cylindrique de révolution centrée sur l'axe central X', qui peut être moulée d'une seule pièce en matière plastique avec le boîtier 42 et qui peut s'étendre selon l'axe central X' depuis la cloison transversale 47 jusqu'à une extrémité libre 51 située au voisinage de la deuxième extrémité 46 du logement de recharge.More particularly, in the example considered here, the charging housing 43 comprises a cup holding member, namely an inner annular wall 50 of generally cylindrical general shape of revolution centered on the central axis X ', which can be molded in one piece of plastic material with the housing 42 and which can extend along the central axis X 'from the transverse partition 47 to a free end 51 located in the vicinity of the second end 46 of the housing of refill.

Cette paroi annulaire 50 peut présenter, au voisinage de son extrémité libre 51, une partie terminale 52 de diamètre intérieur élargi qui délimite ledit épaulement 49. La paroi latérale 12 de la cupule de la cartouche neuve 6 est emboîtée dans cette partie terminale 52, l'extrémité libre 13 de cette paroi latérale étant en appui contre l'épaulement 49 susmentionné.This annular wall 50 may have, in the vicinity of its free end 51, an end portion 52 of enlarged inner diameter which delimits said shoulder 49. The lateral wall 12 of the cup of the new cartridge 6 is nested in this end portion 52, free end 13 of this side wall being in abutment against the shoulder 49 mentioned above.

La paroi annulaire 50 peut comporter intérieurement, au voisinage de son extrémité libre, une lèvre annulaire intérieure 53 qui est en contact avec la paroi latérale 12 de la cupule et qui permet un emboîtement doux de la cupule dans la paroi annulaire 50.The annular wall 50 may comprise internally, in the vicinity of its free end, an inner annular lip 53 which is in contact with the lateral wall 12 of the cup and which allows a soft interlocking of the cup in the annular wall 50.

Le boîtier 42 de la recharge peut en outre comporter un couvercle 54 adapté pour fermer temporairement la deuxième extrémité 46 du logement de recharge.The housing 42 of the refill may further include a cover 54 adapted to temporarily close the second end 46 of the refill housing.

Ce couvercle 54 peut éventuellement être monté pivotant sur la paroi latérale 44 du boîtier. A cet effet, le couvercle 54 peut par exemple présenter une forme d'étrier, incluant :

  • une partie centrale 55 propre à recouvrir la deuxième extrémité 46 du logement de recharge,
  • et deux bras 56 montés pivotants respectivement par deux pivots 57 sur deux faces opposées de la paroi latérale 44 du boîtier 42.
This cover 54 may optionally be pivotally mounted on the side wall 44 of the housing. For this purpose, the cover 54 may for example have a stirrup shape, including:
  • a central portion 55 capable of covering the second end 46 of the charging housing,
  • and two arms 56 pivotally mounted respectively by two pivots 57 on two opposite faces of the side wall 44 of the housing 42.

Les bras 57 peuvent en outre être montés pour coulisser par rapport à la paroi latérale 44 du boîtier entre :

  • une position de fermeture où la partie centrale 56 du couvercle est en appui contre la face d'extrémité du boîtier pour fermer la deuxième extrémité 46 du logement de recharge 43,
  • et une position de dégagement où le couvercle est écarté de ladite deuxième extrémité 46 du logement de recharge, la position de dégagement étant telle que la partie centrale 55 du couvercle est suffisamment éloignée de ladite deuxième extrémité 46 du logement de recharge 43 pour permettre au couvercle de pivoter en libérant ladite deuxième extrémité 46 du logement de recharge.
The arms 57 can also be mounted to slide relative to the side wall 44 of the housing between:
  • a closed position where the central portion 56 of the cover bears against the end face of the housing to close the second end 46 of the charging housing 43,
  • and a release position where the cover is spaced from said second end 46 of the charging housing, the release position being such that the central portion 55 of the cover is sufficiently far away from said second end 46 of the charging housing 43 to allow the cover to pivot by releasing said second end 46 of the charging housing.

Dans l'exemple particulier représenté, les pivots 57 sont formés respectivement sur les faces intérieures en regard 58 des bras 56 (voir les figures 6 à 8) et ces pivots 57 sont montés coulissants respectivement dans deux rainures 59 qui sont ménagées dans les faces de la paroi latérale 44 disposées en regard des bras 56. Chacune des rainures 59 est ouverte vers le bras 56 correspondant et s'étend longitudinalement parallèlement à l'axe central X'. Avantageusement, chaque rainure 59 peut comporter un ou plusieurs rétrécissements 61 qui délimitent au moins un logement de rétention 60 à l'extrémité de la rainure 59 qui est opposée à la deuxième extrémité 46 du logement de recharge 43. Ce logement de rétention 60 reçoit le pivot 57 correspondant lorsque le couvercle 54 est en position fermée, comme représenté sur les figures 6 à 8, et permet alors d'empêcher ledit pivot 57 de coulisser par inadvertance.In the particular example shown, the pivots 57 are respectively formed on the inner facing faces 58 of the arms 56 (see FIGS. Figures 6 to 8 ) and these pivots 57 are slidably mounted respectively in two grooves 59 which are formed in the faces of the side wall 44 disposed opposite the arms 56. Each of the grooves 59 is open towards the corresponding arm 56 and extends longitudinally parallel to the central axis X '. Advantageously, each groove 59 may comprise one or more constrictions 61 which delimit at least one retention housing 60 at the end of the groove 59 which is opposed to the second end 46 of the charging housing 43. This retention housing 60 receives the corresponding pivot 57 when the cover 54 is in the closed position, as shown in FIGS. Figures 6 to 8 , and then makes it possible to prevent said pivot 57 from inadvertently sliding.

Eventuellement, chaque rainure 59 peut également comporter un deuxième rétrécissement 61 à son extrémité opposée, de façon à définir un deuxième logement de rétention 60 propre à retenir les pivots 57 en position lorsqu'un utilisateur les a fait coulisser pour faire passer le couvercle 54 en position de dégagement. Les rétrécissements 61 sont suffisamment peu marqués pour pouvoir se déformer élastiquement et permettre le passage des pivots 57 lorsqu'un utilisateur fait volontairement coulisser le couvercle 54.Optionally, each groove 59 may also include a second constriction 61 at its opposite end, so as to define a second retention housing 60 adapted to hold the pivots 57 in position when a user has slid them to pass the cover 54 into position. release position. The constrictions 61 are sufficiently marked to be able to deform elastically and allow the passage of the pivots 57 when a user intentionally slides the cover 54.

Comme représenté sur la figure 6, le boîtier 42 de la recharge peut en outre comporter un logement d'extraction 62, qui peut présenter une forme cylindrique de révolution centrée sur l'axe X' et être ouvert à l'opposé du logement de recharge 43. Ce logement d'extraction 62 peut notamment s'étendre selon l'axe X', depuis la cloison transversale 47 jusqu'à une extrémité ouverte 63, et il peut contenir au moins un organe d'extraction 64 qui est adapté pour pénétrer dans le reste du bâton 8 de produit d'une recharge usagée 6 d'un dispositif applicateur 1, cet organe d'extraction 64 ayant un rebord externe 66 adapté pour coopérer avec le rebord interne 14 de la cupule de la cartouche usagée de façon à retenir ledit rebord interne et permettre d'extraire la cartouche usagée du dispositif applicateur.As shown on the figure 6 , the housing 42 of the refill may further comprise an extraction housing 62, which may have a cylindrical shape of revolution centered on the axis X 'and be open opposite the charging housing 43. This housing of extraction 62 may in particular extend along the axis X ', from the transverse partition 47 to an open end 63, and it may contain at least one extraction member 64 which is adapted to penetrate the rest of the stick 8 the product of a used refill 6 of an applicator device 1, this extraction member 64 having an outer rim 66 adapted to cooperate with the internal rim 14 of the cup of the used cartridge so as to retain said inner rim and allow extracting the used cartridge from the applicator device.

Dans la première forme de réalisation de l'invention, l'organe d'extraction présente au moins une paroi s'étendant selon l'axe X', depuis la cloison transversale 57 vers l'extrémité ouverte 63 du logement d'extraction, jusqu'à une extrémité libre 65 qui est dotée du rebord externe 66, lequel rebord externe 66 est conformé pour venir s'accrocher sous le rebord interne 14 de la cupule de la cartouche usagée. Plus précisément, le rebord externe 66 de l'organe d'extraction 64 peut comporter un épaulement 68 orienté vers la cloison transversale 57 et adapté pour venir s'accrocher sous le rebord interne 14 de la cupule de la cartouche usagée. Avantageusement, le rebord externe 66 peut également présenter une surface de came 67 s'étendant en biais radialement vers l'extérieur en direction de la cloison transversale 47 jusqu'à l'épaulement 68, qui peut être perpendiculaire à l'axe X'.In the first embodiment of the invention, the extraction member has at least one wall extending along the axis X ', from the transverse partition 57 to the open end 63 of the extraction housing, until at a free end 65 which is provided with the outer rim 66, which outer rim 66 is shaped to come hang under the inner rim 14 of the cup of the used cartridge. More specifically, the outer rim 66 of the extraction member 64 may include a shoulder 68 facing the transverse wall 57 and adapted to hook under the inner rim 14 of the cup of the used cartridge. Advantageously, the outer flange 66 may also have a cam surface 67 extending radially outwardly in the direction of the transverse partition 47 to the shoulder 68, which may be perpendicular to the axis X '.

Dans l'exemple représenté sur les dessins, l'organe d'extraction 64 se présente sous la forme d'une virole de forme sensiblement cylindrique de révolution centrée sur l'axe X', mais cette virole pourrait être remplacée par exemple par une pluralité de pattes dotées chacune d'un rebord externe 66.In the example shown in the drawings, the extraction member 64 is in the form of a shell of substantially cylindrical shape of revolution centered on the axis X ', but this shell could be replaced for example by a plurality legs each having an outer rim 66.

La recharge 41 qui vient d'être décrite peut être utilisée comme suit.The refill 41 which has just been described can be used as follows.

Lorsque le bâton 8 de produit d'un dispositif applicateur 1 est usagé, comme représenté sur la figure 9, on emmanche la deuxième extrémité 4 du tube protecteur 2 de ce dispositif applicateur 1, dans le logement d'extraction 62 du boîtier de la recharge 41. Avantageusement, le diamètre intérieur du logement d'extraction 62 est sensiblement égal au diamètre extérieur de la virole métallique 5 (ou au diamètre extérieur du tube protecteur 2 s'il n'est pas doté d'un telle virole 5), de façon que cet emmanchement aligne l'axe central X' de la recharge 41 avec l'axe central X du dispositif applicateur 1.When the product stick 8 of an applicator device 1 is used, as shown in FIG. figure 9 , the second end 4 of the protective tube 2 of this applicator device 1 is connected to the extraction housing 62 of the charging case 41. Advantageously, the internal diameter of the extraction housing 62 is substantially equal to the external diameter of the metal ferrule 5 (or the outside diameter of the protective tube 2 if it is not provided with such a ferrule 5), so that this fitting aligns the central axis X 'of the refill 41 with the central axis X of the applicator device 1.

Au cours de ce mouvement, lorsque l'utilisateur appuie sur la recharge 41 dans le sens de la flèche 69, l'organe d'extraction 64 pénètre dans le bâton de produit usagé 8, au niveau de la périphérie de ce bâton, et pénètre à l'intérieur de la paroi latérale 12 de la cupule. Le produit constituant le bâton de produit 8 est suffisamment tendre pour permettre cette pénétration. Le diamètre extérieur de l'organe d'extraction 64 est sensiblement égal ou légèrement inférieur au diamètre intérieur de la paroi latérale 12, en dehors des rebords 14 et 66, de sorte que l'extrémité libre 65 de l'organe d'extraction 64 peut pénétrer dans difficulté dans l'extrémité libre 13 de la cupule 7, puis la face inclinée 15 et la surface de came 67 coopèrent ensemble en déformant élastiquement l'organe d'extraction 64 et la paroi latérale 12 de la cupule pour permettre au rebord externe 66 de l'organe d'extraction de passer le rebord interne 14 de la cupule, après quoi le rebord externe 66 de l'organe d'extraction s'accroche sous le rebord interne 14 de la cupule par clipsage, comme représenté plus en détail sur la figure 9a.During this movement, when the user presses the refill 41 in the direction of the arrow 69, the extraction member 64 enters the stick of used product 8, at the periphery of the stick, and enters inside the side wall 12 of the cup. The product constituting the product stick 8 is sufficiently soft to allow this penetration. The outer diameter of the extraction member 64 is substantially equal to or slightly less than the inside diameter of the wall 12, outside the flanges 14 and 66, so that the free end 65 of the extraction member 64 can penetrate into difficulty in the free end 13 of the cup 7, then the inclined face 15 and the surface cam members 67 cooperate together by elastically deforming the extraction member 64 and the side wall 12 of the cup to allow the outer rim 66 of the extraction member to pass the inner rim 14 of the cup, after which the rim outer 66 of the extraction member clings under the inner rim 14 of the cup by clipping, as shown in more detail on the figure 9a .

La cartouche usagée 6 du dispositif applicateur 1 est alors solidement accrochée sur l'organe d'extraction 64, de sorte que l'utilisateur peut détacher cette cartouche usagée 6 du coulisseau 24 du dispositif applicateur, en exerçant une traction sur la recharge 41 dans le sens de la flèche 70 (voir la figure 10). La cartouche usagée 6 se retrouve ainsi entièrement contenue dans le logement d'extraction 63 de la recharge 41 et l'opération d'extraction de cette cartouche usagée se fait aisément et sans salissure pour l'utilisateur.The used cartridge 6 of the applicator device 1 is then firmly attached to the extraction member 64, so that the user can detach the used cartridge 6 from the slide 24 of the applicator device, by exerting traction on the refill 41 in the direction of the arrow 70 (see figure 10 ). The used cartridge 6 is thus completely contained in the extraction housing 63 of the refill 41 and the extraction operation of this used cartridge is easily and without fouling for the user.

Lorsque l'utilisateur souhaite ensuite mettre en place la cartouche neuve 6 de la recharge 41 sur le dispositif applicateur 1, il ouvre la deuxième extrémité 46 du logement de recharge 43, comme représenté sur les figures 11 et 12.When the user then wishes to place the new cartridge 6 of the refill 41 on the applicator device 1, it opens the second end 46 of the charging compartment 43, as shown in FIGS. Figures 11 and 12 .

A cet effet, l'utilisateur soulève d'abord le couvercle 54 en faisant coulisser les pivots 57 de ce couvercle dans les fentes correspondantes 59 du boîtier 42 de la recharge, dans le sens de la flèche 71 de la figure 11.For this purpose, the user first raises the cover 54 by sliding the pivots 57 of this cover in the corresponding slots 59 of the housing 42 of the refill, in the direction of the arrow 71 of the figure 11 .

Le couvercle se trouve alors dans sa position de dégagement, qui lui permet de pivoter librement sur le boîtier 42, comme représenté par la flèche 72 de la figure 12. Si la deuxième extrémité 46 du logement de recharge 43 était initialement fermée par la membrane 48 susmentionnée, l'utilisateur enlève cette membrane 48 au cours de cette opération, et ledit utilisateur oriente également la recharge 41 de façon que le logement de recharge 43 se trouve en face de la deuxième extrémité 4 du tube protecteur 2 du dispositif applicateur 1.The cover is then in its release position, which allows it to pivot freely on the housing 42, as represented by the arrow 72 of the figure 12 . If the second end 46 of the charging compartment 43 was initially closed by the aforementioned membrane 48, the user removes the membrane 48 during this operation, and said user also directs the refill 41 so that the charging housing 43 is opposite the second end 4 of the protective tube 2 of the applicator device 1.

Comme représenté sur la figure 13, l'utilisateur emmanche alors le tube protecteur 2 du dispositif applicateur dans le logement de recharge 43 de la recharge, lequel logement de recharge présente un diamètre intérieur sensiblement égal au diamètre extérieur de la virole 5 du tube protecteur 2 (ou sensiblement égal au diamètre extérieur du tube protecteur 2 si la virole 5 est omise), de sorte que l'axe central X' de la recharge se trouve alors aligné avec l'axe central X du dispositif applicateur lorsque la recharge 41 est engagée sur le tube protecteur 2 par déplacement dans le sens de la flèche 73 visible sur la figure 13. Par ailleurs, le diamètre extérieur de la paroi annulaire 50 du logement de recharge peut être sensiblement égal au diamètre intérieur du tube protecteur 2, de façon à pouvoir s'engager à l'intérieur du tube protecteur 2 au cours de ce mouvement, en contribuant ainsi au guidage de la recharge 41. Il est en effet particulièrement préféré de pouvoir disposer de moyens de recentrage entre la partie intérieure du dispositif de recharge 43 et la virole 5 en vue de l'accrochage de la recharge usagée.As shown on the figure 13 , the user then moves the protective tube 2 of the applicator device into the recharging compartment 43 of the refill, which refill housing has an inside diameter substantially equal to the outside diameter of the shell 5 of the protective tube 2 (or substantially equal to the diameter outside the protective tube 2 if the ferrule 5 is omitted), so that the central axis X 'of the refill is then aligned with the central axis X of the applicator device when the refill 41 is engaged on the protective tube 2 by movement in the direction of the arrow 73 visible on the figure 13 . Moreover, the outside diameter of the annular wall 50 of the refill housing may be substantially equal to the inside diameter of the protective tube 2, so as to be able to engage inside the protective tube 2 during this movement, by contributing and in guiding the refill 41. It is indeed particularly preferred to have refocusing means between the inner portion of the refill device 43 and the shell 5 for attachment of the used refill.

L'utilisateur appuie ensuite sur le boîtier 42 de la recharge 41 dans le sens de la flèche 73, ou bien sur le couvercle après l'avoir repositionné selon l'axe XX', jusqu'à ce que le téton élastique 35 de la cupule 7 de la recharge neuve 6 se clipse dans l'ouverture centrale 34 du coulisseau 24 appartenant au dispositif applicateur 1. Ce clipsage peut être repéré par l'utilisateur grâce au bruit caractéristique de "clic" émis alors par le téton élastique 35 lors du clipsage, puis il retire la recharge 41 dans le sens inverse de la flèche 73. Le dispositif applicateur 1 se retrouve alors dans la situation des figures 2 et 3, avec une cartouche de produit 6 neuve.The user then presses on the case 42 of the refill 41 in the direction of the arrow 73, or on the cover after repositioning it along the axis XX ', until the elastic stud 35 of the cup 7 of the new refill 6 is clipped into the central opening 34 of the slider 24 belonging to the applicator device 1. This clipping can be identified by the user thanks to the characteristic noise of "click" then issued by the resilient nipple 35 during clipping , then it removes the refill 41 in the opposite direction to the arrow 73. The applicator device 1 is then found in the situation of the figures 2 and 3 , with a new product cartridge 6.

De préférence, l'utilisateur prendra soin avant toute étape de rechargement, en particulier lors de la mise en place d'une nouvelle cartouche de produit, de mettre la cupule portant le bâton de produit usagé dans la position la plus basse possible, afin de limiter les risques éventuels d'endommager le dispositif applicateur lors de l'accrochage. Il en va de même pour le nouveau bâton de produit lors de l'étape finale d'enlèvement de la recharge.Preferably, the user will take care before any refueling step, especially when setting up a new product cartridge, to put the cup carrying the stick of used product in the lowest possible position, to limit the possible risk of damage to the applicator device during the attachment. The same goes for the new product stick in the final step of removing the refill.

Les deuxième et troisième formes de réalisation de l'invention, représentées sur les figures 14 à 20a, présentent de nombreux points communs avec la première forme de réalisation de l'invention et ne seront donc pas décrites en totalité ci-après. Seules seront décrites ci-après les différences de ces deuxième et troisième formes de réalisation de l'invention par rapport à la première forme de réalisation décrite précédemment, étant entendu que les avantages déjà décrits pour la première forme de réalisation sont conservés dans la deuxième forme de réalisation.The second and third embodiments of the invention, represented on the Figures 14 to 20a , have many points in common with the first embodiment of the invention and therefore will not be fully described hereinafter. Only the differences of these second and third embodiments of the invention will be described below with respect to the first embodiment described above, it being understood that the advantages already described for the first embodiment are retained in the second embodiment. of realization.

B. Deuxième forme de réalisation de l'invention B. Second embodiment of the invention

Dans la deuxième forme de réalisation de l'invention, le dispositif applicateur 1 se distingue de la première forme de réalisation de l'invention uniquement par le fait que le rebord intérieur 114 de la cupule 7 se présente sous la forme d'un filetage ménagé à l'intérieur de la paroi latérale 12 de cette cupule, comme on peut le voir notamment sur les figures 14 et 15. De plus, le rebord extérieur 166 de l'organe d'extraction 64 de la recharge peut également se présenter sous la forme d'un filetage extérieur, adapté pour se visser dans le filetage intérieur de la cupule 7 de la cartouche de cosmétique (voir la figure 15).In the second embodiment of the invention, the applicator device 1 is distinguished from the first embodiment of the invention only by the fact that the inner rim 114 of the cup 7 is in the form of a threaded opening inside the lateral wall 12 of this cup, as can be seen in particular on the figures 14 and 15 . In addition, the outer rim 166 of the extraction member 64 of the refill can also be in the form of an external thread, adapted to be screwed into the internal thread of the cup 7 of the cosmetic cartridge (see the figure 15 ).

Ainsi, comme représenté sur les figures 16 et 16a, lors de l'opération d'extraction de la cartouche 6 usagée du dispositif applicateur 1, le logement d'extraction 62 de la recharge 41 est d'abord emboîté à l'extérieur du tube protecteur 2 du dispositif applicateur dans le sens de la flèche 69, puis l'utilisateur fait tourner la recharge 41 autour de son axe central X' dans le sens du vissage, de façon à visser le filetage 166 de l'organe d'extraction 64 sur le filetage interne 114 de la cupule 7 de la cartouche usagée tout en faisant pénétrer l'organe d'extraction dans le béton 8 de produit, comme représenté sur les figure 16 et 16a.Thus, as represented on the Figures 16 and 16a during the operation of extracting the used cartridge 6 from the applicator device 1, the extraction housing 62 of the refill 41 is first fitted on the outside of the protective tube 2 of the applicator device in the direction of the arrow 69, then the user rotates the refill 41 about its central axis X 'in the screwing direction, so as to screw the thread 166 of the extraction member 64 on the internal thread 114 of the cup 7 of the cartridge used while penetrating the extraction member in the concrete product 8, as shown in figure 16 and 16a .

La cartouche usagée 6 peut alors être extraite du dispositif applicateur 1 par traction dans le sens inverse de la flèche 69, de la même façon qu'expliqué précédemment pour la première forme de réalisation de l'invention, et la cartouche neuve 6 contenue dans le logement de recharge 43 peut ensuite être mise en place sur le dispositif applicateur 1 par simple emboîtement dans le sens de la flèche 73 (voir la figure 17), de la même façon que dans la première forme de réalisation de l'invention.The used cartridge 6 can then be extracted from the applicator device 1 by pulling in the opposite direction of the arrow 69, in the same way as previously explained for the first embodiment of the invention, and the new cartridge 6 contained in the recharge housing 43 can then be put in place on the applicator device 1 by simply interlocking in the direction of arrow 73 (see FIG. figure 17 ), in the same way as in the first embodiment of the invention.

C. Troisième forme de réalisation de l'invention C. Third embodiment of the invention

Dans la troisième forme de réalisation de l'invention, comme représenté sur les figures 18 et 19, la cartouche 6 de produit se distingue de celle de la première forme de réalisation par le fait que la paroi latérale 12 de la cupule de cette cartouche ne comporte plus de rebord intérieur. En revanche, le fond 11 de cette cupule est doté d'une ouverture centrale 274 qui délimite un rebord intérieur 214 constitué par la portion du fond 11 entourant l'ouverture centrale 274, au centre du téton élastique 235. Le rebord 214 est recouvert par le produit 8 vers l'intérieur de la cupule, comme dans les autres formes de réalisation de l'invention.In the third embodiment of the invention, as shown in figures 18 and 19 , the product cartridge 6 differs from that of the first embodiment in that the side wall 12 of the cup of this cartridge no longer has an inner rim. In contrast, the bottom 11 of this cup has a central opening 274 which delimits an inner rim 214 constituted by the portion of the bottom 11 surrounding the central opening 274, in the center of the resilient nipple 235. The rim 214 is covered by the product 8 to the interior of the cup, as in the other embodiments of the invention.

Ce téton élastique 235 peut avantageusement présenter un diamètre supérieur au téton élastique 35 de la première forme de réalisation, ledit téton élastique 235 pouvant par exemple présenter une paroi latérale 236 cylindrique de révolution autour de l'axe X, dotée à son extrémité libre d'une lèvre extérieure 237 permettant le clipsage du téton élastique 235 dans l'ouverture centrale 274 du coulisseau 24 du dispositif applicateur (voir la figure 18). Cette ouverture centrale 274 peut le cas échéant être plus large que l'ouverture centrale 34 de la première forme de réalisation de l'invention, et la vis 223 du dispositif applicateur peut se différencier de la vis 23 de la première forme de réalisation par le fait que ses deux parois latérales planes 226, similaires aux parois latérales 26 de la première forme de réalisation, sont plus éloignées l'une de l'autre que ne le sont les parois latérales 26 dans la première forme de réalisation de l'invention.This elastic stud 235 may advantageously have a larger diameter than the elastic stud 35 of the first embodiment, said elastic stud 235 may for example have a cylindrical side wall 236 of revolution about the X axis, provided at its free end with an outer lip 237 for clipping the resilient nipple 235 in the central opening 274 of the slide 24 of the applicator device (see FIG. figure 18 ). This central opening 274 may, where appropriate, be wider than the central opening 34 of the first embodiment of the invention, and the screw 223 of the applicator device may be different from the screw 23 of the first embodiment by the that his two flat side walls 226, similar to the side walls 26 of the first embodiment, are farther apart than the side walls 26 in the first embodiment of the invention.

L'évidement 230 de la paroi transversale 31 est conformé en correspondance avec la forme des parois latérales 226 susmentionnées.The recess 230 of the transverse wall 31 is shaped in correspondence with the shape of the aforementioned side walls 226.

Par ailleurs, comme représenté sur la figure 19, l'organe d'extraction 264 du boîtier 42 de la recharge peut éventuellement se présenter sous la forme d'une tige 264 disposée avantageusement au centre du logement d'extraction 63 et s'étendant selon l'axe central X' de la recharge depuis la cloison transversale 47 jusqu'à une extrémité libre 265 formant une tête saillante qui délimite le rebord externe 266 adapté pour coopérer avec le rebord interne 214 de la cupule.Moreover, as represented on the figure 19 , the extraction member 264 of the housing 42 of the refill may optionally be in the form of a rod 264 advantageously disposed in the center of the extraction housing 63 and extending along the central axis X 'of the refill from the transverse partition 47 to a free end 265 forming a protruding head which defines the outer flange 266 adapted to cooperate with the inner rim 214 of the cup.

Ce rebord externe 266 peut être adapté pour s'accrocher, notamment par clipsage, sous le rebord interne 214 de la cupule, et ledit rebord externe 266 peut avantageusement présenter une surface de came 267 s'étendant en biais radialement vers l'extérieur en direction de la cloison transversale 47, jusqu'à un épaulement 268 orienté vers ladite cloison transversale 47 et disposé avantageusement perpendiculairement à l'axe central X'.This outer rim 266 may be adapted to catch, in particular by clipping, under the internal rim 214 of the cup, and said outer rim 266 may advantageously have a cam surface 267 extending radially outwardly in the direction of the transverse partition 47, to a shoulder 268 oriented towards said transverse partition 47 and advantageously arranged perpendicularly to the central axis X '.

Ainsi, comme représenté sur les figures 20 et 20a, lorsqu'un utilisateur souhaite extraire une cartouche usagée 6 du dispositif applicateur 1, il emboîte le logement d'extraction 62 de la recharge sur le tube protecteur 2 du dispositif applicateur en faisant pénétrer l'organe d'extraction 264 dans le bâton 8 de produit de la recharge usagée, jusqu'à ce que le rebord 266 de l'organe d'extraction se clipse sous le rebord interne 214 de la cupule, après quoi la cartouche usagée 6 peut être extraite du dispositif applicateur en exerçant une traction sur la recharge 41 dans le sens inverse de la flèche 71.Thus, as represented on the figures 20 and 20a when a user wishes to extract a used cartridge 6 from the applicator device 1, he fits the extraction housing 62 of the refill on the protective tube 2 of the applicator device by making the extraction member 264 enter the stick 8 of produced the used refill, until the edge 266 of the extraction member is clipped under the inner rim 214 of the cup, after which the used cartridge 6 can be extracted from the applicator device by exerting a pull on the recharge 41 in the opposite direction of arrow 71.

Enfin, la mise en place de la cartouche neuve 6 de la recharge sur le dispositif applicateur 1 se fait de la même façon que dans les deux premières formes de réalisation de l'invention, par simple emboîtement du logement de recharge 43 de la recharge 41 sur le tube protecteur 2 du dispositif applicateur, dans le sens de la flèche 73, comme représenté sur la figure 1.Finally, the introduction of the new cartridge 6 of recharging on the applicator device 1 is done in the same way as in the first two embodiments of the invention, by simple interlocking of the charging housing 43 of the refill 41 on the protective tube 2 of the applicator device, in the direction of the arrow 73, as shown on the figure 1 .
