Description

La présente invention concerne les étuis destinés à contenir et à utiliser des produits pâteux relativement rigides notamment des fards tels que des rouges à lèvres ou encore des cirages ou des produits analogues qui présentent une consistance cireuse et qui doivent être appliqués par frottement soit sur des parties du corps, soit sur des objets divers. Dans ce qui suit, ces produits sont dits solidifiés.The present invention relates to cases intended to contain and use relatively rigid pasty products, in particular make-up such as lipsticks or even polishes or the like which have a waxy consistency and which must be applied by rubbing either on parts of the body, either on various objects. In what follows, these products are said to be solidified.

Il est habituel dans la technique de mouler ces produits à consistance cireuse lorsqu'ils sont liquides puis de les mettre en place dans des étuis lorsqu'ils sont solidifiés.It is usual in the art to mold these waxy-consistency products when they are liquid and then to place them in cases when they are solidified.

Les étuis, par exemple des bâtons de rouge à lèvres ou de cirage, sont fréquemment munis de poussoirs pour extraire petit à petit le bâton de produit à utiliser ou bien ils sont munis d'un système à vis qui permet de sortir progressivement le produit solidifié.The cases, for example sticks of lipstick or polish, are frequently provided with pushers to gradually extract the stick of product to be used or else they are provided with a screw system which makes it possible to gradually remove the solidified product .

La présente invention concerne un étui nouveau ne comportant qu'un très petit nombre de pièces pouvant toutes être fabriquées simplement, notamment par moulage par injection en matière synthétique et cela tout en permettant un remplissage sans moulage préalable du bâton de produit cireux, c'est-à-dire que c'est l'étui lui-même qui constitue le moule.The present invention relates to a new case comprising only a very small number of parts which can all be manufactured simply, in particular by injection molding in synthetic material and this while allowing filling without prior molding of the stick of waxy product, it is that is, the case itself which constitutes the mold.

Les opérations de montage et de fabrication sont ainsi rendues très simples.The assembly and manufacturing operations are thus made very simple.

Par FR-A-1 458 448, on connaît un étui distributeur pour produits solidifiés comportant un corps tubulaire muni d'un piston et fermé par un couvercle amovible, ledit piston délimitant une ouverture pour l'introduction du produit remplissant au moins une chambre interne dudit corps et des moyens d'obturation étant prévus pour empêcher l'écoulement du produit après remplissage de la chambre, qui correspond au préambule de la revendication 1.By FR-A-1 458 448, there is known a dispensing case for solidified products comprising a tubular body provided with a piston and closed by a removable cover, said piston defining an opening for the introduction of the product filling at least one internal chamber. said body and closing means being provided to prevent the flow of the product after filling the chamber, which corresponds to the preamble of claim 1.

Cependant, avec une telle disposition, l'étui distributeur n'est pas étanche.However, with such an arrangement, the dispenser case is not waterproof.

L'invention s'en distingue par la partie caractérisante de la revendication 1.The invention is distinguished by the characterizing part of claim 1.

Diverses autres caractéristiques de l'invention ressortent d'ailleurs de la description détaillée qui suit.Various other characteristics of the invention will also emerge from the detailed description which follows.

La fig. 15 est une coupe prise suivant la ligne XV-XV de la fig. 14.Fig. 15 is a section taken on the line XV-XV of FIG. 14.

L'étui illustré au dessin comporte un corps 1 réalisé, de même que les autres pièces décrites dans ce qui suit, de préférence en matière synthétique moulée par injection.The case illustrated in the drawing comprises a body 1 produced, as well as the other parts described in the following, preferably made of injection-molded synthetic material.

Le corps 1 délimite une chambre 2. A sa partie supérieure, le corps 1 présente un épaulement 3 surmonté par une partie filetée 4 sur laquelle est vissé un couvercle 5. Le fond du corps 1 est ouvert et il présente latéralement au moins une ouverture 6, par exemple deux diamétralement opposées comme représenté.The body 1 defines a chamber 2. At its upper part, the body 1 has a shoulder 3 surmounted by a threaded part 4 on which a cover is screwed 5. The bottom of the body 1 is open and it has laterally at least one opening 6, for example two diametrically opposite as shown.

Le dessin montre que la paroi lisse interne 7 du corps 1 coïncide avec la paroi interne 8 du couvercle 5. Il est avantageux que la paroi interne du couvercle délimite un tronc de cône ou présente un rayon plus petit que celui du corps 1 qui est cylindrique.The drawing shows that the internal smooth wall 7 of the body 1 coincides with the internal wall 8 of the cover 5. It is advantageous that the internal wall of the cover delimits a truncated cone or has a smaller radius than that of the body 1 which is cylindrical .

Un piston 9 est engagé dans le corps 1 ; ce piston présente une paroi interne 10 formant une cuvette avantageusement en contre-dépouille ou est muni de saillies d'accrochage. Le piston 9 présente un fond 11 auquel est raccordé un fourreau 12 ouvert.A piston 9 is engaged in the body 1; this piston has an internal wall 10 forming a bowl advantageously undercut or is provided with hooking projections. The piston 9 has a bottom 11 to which an open sheath 12 is connected.

Le fourreau 12 présente un filetage 13 en prise avec le filet 14 d'un taraudage que comporte une collerette 15 formée à l'intérieur du corps 1. Le taraudage 13 est également en prise avec des doigts ou nervures 16 que forme une coupelle 17 engagée dans le corps 1 dans lequel elle est clipsée par un jonc 18 ou analogue.The sleeve 12 has a thread 13 engaged with the thread 14 of a tapping that comprises a flange 15 formed inside the body 1. The tapping 13 is also engaged with fingers or ribs 16 formed by a cup 17 engaged in the body 1 in which it is clipped by a rod 18 or the like.

La coupelle 17 est guidée, à sa partie supérieure, dans une rainure 19 délimitée entre la paroi interne du corps 1 et la collerette 15.The cup 17 is guided, at its upper part, in a groove 19 delimited between the internal wall of the body 1 and the flange 15.

La coupelle 17 comporte aussi un fond 17a à partir duquel fait saillie un manchon 20 dont la paroi externe porte contre un organe d'étanchéité 21, par exemple une lèvre ou bourrelet, formé à partir de la paroi interne du fourreau 12. Il est avantageux, dans la réalisation de la fig. 1, qu'au moins la partie de la coupelle 17 qui se trouve en regard des ouvertures 6, soit moletée ou autrement rendue rugueuse.The cup 17 also includes a bottom 17a from which protrudes a sleeve 20 whose external wall bears against a sealing member 21, for example a lip or bead, formed from the internal wall of the sleeve 12. It is advantageous , in the embodiment of FIG. 1, that at least the part of the cup 17 which is located opposite the openings 6, is knurled or otherwise made rough.

Lors de la fabrication, le corps 1, qui est avantageusement réalisé en une seule pièce en matière synthétique moulée par injection, est muni du piston 9 réalisé également en matière synthétique moulée par injection en même temps que le fourreau 12. Ensuite, le corps 1 est muni du couvercle 5 puis, cet ensemble, est amené à un dispositif de remplissage dans une position dans laquelle il est tourné de 180° par rapport à la position illustrée à la fig. 1.During manufacture, the body 1, which is advantageously made in a single piece of injection-molded synthetic material, is provided with the piston 9 also made of injection-molded synthetic material at the same time as the sleeve 12. Next, the body 1 is provided with the cover 5 then, this assembly is brought to a filling device in a position in which it is rotated by 180 ° relative to the position illustrated in FIG. 1.

Le produit de remplissage est coulé sous forme liquide à travers une ouverture 11a que présente le fond 11 du piston 9. Après solidification du produit 22, le dispositif est ensuite muni de la coupelle 17 mise en place par guidage des doigts 16 sur le filetage 13 jusqu'à encliquetage du jonc 18 dans le corps 1.The filling product is poured in liquid form through an opening 11a which has the bottom 11 of the piston 9. After solidification of the product 22, the device is then provided with the cup 17 put in place by guiding the fingers 16 on the thread 13 until snap ring 18 in the body 1.

L'étui distributeur est alors prêt à être utilisé.The dispenser case is then ready to use.

Pour obtenir un accès au produit 22 contenu dans la chambre 2, il suffit de retirer le couvercle 5 dans lequel ce produit a été moulé en même temps que dans le corps 1 jusqu'au fond 11 du piston 9. Au fur et à mesure de l'usure du produit 22, il est possible de le faire progressivement sortir du corps 1 en tournant la coupelle 17 à travers la ou les ouvertures 6. En effet, la coupelle ne peut plus être déplacée axialement du fait de son encliquetage dans le corps 1 et, par conséquent, les doigts ou nervures 16 entraînent le fourreau 12 en rotation de sorte que le filetage 13 de celui-ci est vissé dans le filet 14 formant taraudage de la collerette 15, ce qui provoque le déplacement du piston 9 dans le sens axial du corps 1.To obtain access to the product 22 contained in the chamber 2, it suffices to remove the cover 5 in which this product has been molded at the same time as in the body 1 up to the bottom 11 of the piston 9. As and when wear of the product 22, it is possible to gradually remove it from the body 1 by turning the cup 17 through the opening (s) 6. In fact, the cup can no longer be moved axially due to its snap-fastening in the body 1 and, consequently, the fingers or ribs 16 drive the sheath 12 in rotation so that the thread 13 thereof is screwed into the thread 14 forming the thread of the flange 15, which causes the piston 9 to move in the axial direction of the body 1.

La fig. 3 illustre une légère variante selon laquelle la coupelle 17 s'étend au-delà de la base du corps 1 et forme autour de son fond 17a un bouton moleté 17₁. Dans cette réalisation, les ouvertures 6 sont supprimées. Tous les autres organes sont réalisés comme décrits dans ce qui précède en référence à la fig. 1 et portent, par conséquent, les mêmes numéros de référence.Fig. 3 illustrates a slight variant according to which the cup 17 extends beyond the base of the body 1 and forms around its bottom 17a a knurled button 17₁. In this embodiment, the openings 6 are eliminated. All the other members are produced as described in the foregoing with reference to FIG. 1 and therefore bear the same reference numbers.

Pour extraire le produit 22, il suffit, après retrait du couvercle 5, de faire tourner le bouton moleté 17₁ et, par conséquent, la coupelle 17.To extract the product 22, it is sufficient, after removing the cover 5, to turn the knurled knob 17₁ and, consequently, the cup 17.

La fig. 4 illustre une modification selon laquelle le filet de taraudage 14 est directement formé à partir de la paroi interne du corps 1, tandis que le filetage 13 comporte, sur son filet, des stries ou autres protubérances 23 permettant de faire tourner le fourreau 12 à travers la ou les ouvertures 6. Dans cette réalisation, la coupelle, désignée alors par 17₁, est reliée au fourreau par l'organe d'étanchéité 21 et elle forme un bouchon 24 pour le trou 11a du piston 9.Fig. 4 illustrates a modification according to which the tapping thread 14 is directly formed from the internal wall of the body 1, while the thread 13 comprises, on its thread, striations or other protrusions 23 making it possible to rotate the sleeve 12 through the opening or openings 6. In this embodiment, the cup, then designated by 17₁, is connected to the sheath by the sealing member 21 and it forms a plug 24 for the hole 11a of the piston 9.

Comme le montre le dessin, cette réalisation permet d'actionner directement le fourreau 12 pour le visser sur le filet 14 formant taraudage en permettant ainsi d'assurer le déplacement du piston 9.As shown in the drawing, this embodiment makes it possible to actuate the sheath 12 directly to screw it onto the thread 14 forming a tapping, thereby making it possible to move the piston 9.

La fig. 5 montre une réalisation tout à fait analogue à celle de la fig. 1 dans laquelle le corps 1 présente une forme allongée correspondant sensiblement à celle d'un stylographe. Dans cette réalisation, la coupelle 17 est, comme précédemment, maintenue immobile axialement tout en pouvant être déplacée en rotation par le jonc 18 et elle est guidée à son extrémité libre dans une encoche 25 du corps 1. Les autres parties de l'étui sont constituées de la même manière que décrite précédemment et sont, par conséquent, affectées des mêmes numéros de référence.Fig. 5 shows an embodiment completely similar to that of FIG. 1 in which the body 1 has an elongated shape corresponding substantially to that of a stylographer. In this embodiment, the cup 17 is, as before, kept axially immobile while being able to be moved in rotation by the rod 18 and it is guided at its free end in a notch 25 in the body 1. The other parts of the case are constituted in the same way as described above and are therefore assigned the same reference numbers.

La fig. 6 illustre une autre variante selon laquelle la partie du corps 1 qui s'étend entre le piston 9 et le couvercle 5 présente un taraudage 26 et le piston 9 un filet de vis 27. Dans cette réalisation, le piston est relié directement à une coupelle 17₂ et son trou 11a est fermé par un bouchon 24 analogue à celui formé par la coupelle 17₁ de la fig. 4.Fig. 6 illustrates another variant according to which the part of the body 1 which extends between the piston 9 and the cover 5 has a thread 26 and the piston 9 a screw thread 27. In this embodiment, the piston is connected directly to a cup 17₂ and its hole 11a is closed by a plug 24 similar to that formed by the cup 17₁ in fig . 4.

Comme cela ressort du dessin et de la description qui précède, lorsque le produit 22 est coulé et solidifié à l'intérieur du corps 1, il forme lui-même un filetage qui, lorsque le produit doit être utilisé, assure sa sortie progressive en même temps que le piston 9 est entraîné en rotation et vissé dans le taraudage 26.As is apparent from the above drawing and description, when the product 22 is poured and solidified inside the body 1, it itself forms a thread which, when the product is to be used, ensures its gradual exit at the same time while the piston 9 is rotated and screwed into the internal thread 26.

La variante de la fig. 3 peut être mise en oeuvre dans la réalisation des fig. 5 et 6, c'est-à-dire que la coupelle 17 peut être commandée par un bouton moleté 17₁.The variant of fig. 3 can be implemented in the production of FIGS. 5 and 6, that is to say that the cup 17 can be controlled by a knurled button 17₁.

Dans la réalisation des fig. 7 à 12, l'étanchéité entre la coupelle 17 et le corps 1 est assurée par une lèvre mince 28 bien visible à la fig. 10. Il est avantageux que la lèvre mince 28 forme un segment 29 pressé élastiquement contre la paroi externe de la collerette 15. La lèvre mince 28 peut aussi présenter une forme légèrement tronconique pour augmenter la pression élastique qu'elle exerce sur la collerette 15.In the realization of fig. 7 to 12, the seal between the cup 17 and the body 1 is ensured by a thin lip 28 clearly visible in FIG. 10. It is advantageous for the thin lip 28 to form a segment 29 which is pressed elastically against the external wall of the flange 15. The thin lip 28 can also have a slightly frustoconical shape in order to increase the elastic pressure which it exerts on the flange 15.

Il est avantageux que le fond 11 du piston 9 soit constitué par de simples pattes 11₁ soutenues par des nervures 11₂ entre lesquelles l'ouverture 11a est délimitée.It is advantageous that the bottom 11 of the piston 9 is constituted by simple tabs 11₁ supported by ribs 11₂ between which the opening 11a is delimited.

Les pattes 11₁ ont pour effet de délimiter une ouverture 11a en forme de croisillon dont la fonction est exposée dans ce qui suit.The tabs 11₁ have the effect of delimiting an opening 11a in the form of a cross whose function is explained in the following.

Lorsque le fourreau 12 est à paroi mince, il est avantageux, comme le montre la fig. 12, que les doigts ou nervures 16 soient guidés dans des rainures 30 s'étendant jusqu'à des bourrelets 31 formés dans la paroi interne du fourreau 12.When the sheath 12 has a thin wall, it is advantageous, as shown in FIG. 12, that the fingers or ribs 16 are guided in grooves 30 extending up to beads 31 formed in the internal wall of the sleeve 12.

La fig. 13 illustre un mode de remplissage particulier dans lequel le corps 1 est mis en place en position retournée dans un moule 32 comportant une paroi 34 pouvant présenter une forme quelconque. Le dessin la montre plane.Fig. 13 illustrates a particular filling mode in which the body 1 is placed in the inverted position in a mold 32 comprising a wall 34 which may have any shape. The drawing shows it flat.

La chambre 2 est ainsi divisée en deux chambres 2a, 2b et une première quantité de la matière de remplissage est amenée, par exemple coulée, dans la chambre 2a qui s'étend par l'ouverture 11a entre les pattes 11₁.The chamber 2 is thus divided into two chambers 2a, 2b and a first quantity of the filling material is brought, for example poured, into the chamber 2a which extends through the opening 11a between the tabs 11₁.

Après un durcissement suffisant de la matière de remplissage, le corps 1, muni du piston 9, est retiré du moule ou tout en le laissant dans le moule c'est la paroi 34 qui est retirée et une seconde matière de remplissage est amenée, par exemple coulée, dans la chambre 2b. Il est ainsi possible de faire contenir deux produits par le même étui, ces produits se différenciant par leur nature, leur quantité ou seulement leur couleur. Il est d'ailleurs possible de mettre en place plus de deux produits en prévoyant une paroi 34 à plusieurs branches.After a sufficient hardening of the filling material, the body 1, provided with the piston 9, is removed from the mold or while leaving it in the mold it is the wall 34 which is removed and a second filling material is brought, by example casting, in room 2b. It is thus possible to contain two products in the same case, these products differing in their nature, their quantity or only their color. It is also possible to install more than two products by providing a wall 34 with several branches.

Les fig. 14 et 15 montrent qu'il est également possible d'effectuer un remplissage en disposant des produits différents de manière plus ou moins concentrique et en utilisant l'étui en tant que moule comme décrit précédemment.Figs. 14 and 15 show that it is also possible to carry out a filling by arranging different products more or less concentrically and by using the case as a mold as described above.

Il suffit ainsi que cela est illustré de mettre en place dans l'ouverture laissée libre par les pattes 11₁ un tube 35, d'amener dans la chambre extérieure 2c ou dans la chambre intérieure 2d un premier produit, d'attendre son durcissement, de retirer le tube puis d'amener dans celle des deux chambres non remplies au moins un second produit de remplissage.It suffices, as illustrated, to put a tube 35 in the opening left free by the legs 11₁, to bring a first product into the outer chamber 2c or into the inner chamber 2d, wait for it to harden, remove the tube then bring in that of the two unfilled chambers at least one second filling product.

Si le tube 35 est muni d'ailettes saillantes, il est également possible en remplissant tout d'abord les chambres 2c de remplir ces chambres de produits différents, puis après retrait du tube 35 dont les ailettes passent entre les pattes 11 d'amener un produit de remplissage pour la chambre 2d et les espaces laissés libres entre le produit de remplissage des différentes chambres 2c délimitées par les ailettes.If the tube 35 is provided with projecting fins, it is also possible by first filling the chambers 2c to fill these chambers with different products, then after removal of the tube 35, the fins of which pass between the legs 11 to bring a filling product for the chamber 2d and the spaces left free between the filling product for the various chambers 2c delimited by the fins.

Les fig. 14 et 15 montrent qu'un moule n'est pas indispensable, celui-ci étant constitué directement par le corps 1 et son couvercle 5 dont la paroi interne 8 est avantageusement constituée par une lèvre flexible 36 bien visible à la fig. 14 ainsi qu'à la fig. 11, cette lèvre exerçant une pression élastique par son extrémité effilée contre la paroi interne ou externe 7 du corps 1, paroi interne qui est elle-même avantageusement constituée par une partie amincie 1a du corps 1 de manière que le couvercle 5, qui est vissé sur ce corps, présente des génératrices pouvant être alignées avec celles de la paroi extérieure dudit corps.Figs. 14 and 15 show that a mold is not essential, the latter being formed directly by the body 1 and its cover 5, the internal wall 8 of which is advantageously constituted by a flexible lip 36 clearly visible in FIG. 14 as well as in FIG. 11, this lip exerting an elastic pressure by its tapered end against the internal or external wall 7 of the body 1, internal wall which is itself advantageously constituted by a thinned part 1a of the body 1 so that the cover 5, which is screwed on this body, has generators that can be aligned with those of the outer wall of said body.
