Description

CONDITIONNEMENT EN MATIERE PLASTIQUE INJECTEE POUR PRODUIT COSMETIQUE PACKAGING IN INJECTED PLASTIC MATERIAL FOR COSMETIC PRODUCT
La présente invention se rapporte principalement à un conditionnement destiné à contenir un produit cosmétique, liquide ou pâteux, en particulier du mascara.The present invention relates mainly to a packaging intended to contain a cosmetic product, liquid or pasty, in particular mascara.
L'invention s'applique au domaine du conditionnement en cosmétique. Un conditionnement pour produit cosmétique, comme les mascaras, les fards à paupière, les brillants à lèvre ou les souligneurs, se compose habituellement d'une flaconnette ouverte munie d'un essoreur et d'une capsule sur laquelle est solidarisée une tige terminée par un applicateur pour appliquer le produit contenu dans la flaconnette, par exemple une brosse ou un peigne de mascara, un pinceau ou un embout mousse.The invention applies to the field of packaging in cosmetics. A packaging for cosmetic product, such as mascaras, eyeshadows, lip glosses or highlighters, usually consists of an open vial provided with a wringer and a capsule on which a rod terminated by a applicator for applying the product contained in the bottle, for example a brush or a mascara comb, a brush or a foam tip.
La capsule est vissée sur la flaconnette. Lorsque l'applicateur est retiré de la flaconnette, une lèvre interne de l'essoreur, s'étendant radialement, vient en contact avec l'applicateur pour retirer l'excédent de produit.The capsule is screwed onto the bottle. When the applicator is removed from the vial, an internal lip of the wiper, extending radially, comes into contact with the applicator to remove the excess product.
Classiquement, la flaconnette est réalisée par injection/soufflage ou extrusion/soufflage. Or le soufflage impose certains types de forme " soufflables " et limite donc la composition chimique des plastiques à ceux qui présentent une transition vitreuse, par exemple le polypropylène ou le polyéthylène. En outre, le vissage de la capsule nécessite une forme cylindrique ou un système d'indexation particulier.Conventionally, the bottle is produced by injection / blowing or extrusion / blowing. However, blowing imposes certain types of "blown" shape and therefore limits the chemical composition of plastics to those which have a glass transition, for example polypropylene or polyethylene. In addition, the screwing of the capsule requires a cylindrical shape or a specific indexing system.
De plus, cette technique ne permet pas d'obtenir une bonne régularité de l'épaisseur des parois, ce qui se traduit par des défauts d'état de surface : effet " peau d'orange " lié à l'échappement de l'air mal contrôlé au soufflage, ou " couture " longitudinale liée au plan de joint. Ces défauts empêchent l'utilisation de certaines techniques de décoration, décors par exemple réalisés avec les techniques lithographiques, et imposent en général la mise en place d'opérations de finition (vernis, laquage, ...). Par ailleurs, l'un des aspects les plus importants concerne les problèmes d'étanchéité liés à la volatilité des produits cosmétiques. Seul le vissage est réputé pouvoir réaliser une étanchéité suffisamment efficace pour les produits cosmétiques, et toute autre technique de fermeture est donc a priori rejetée. Ce « blocage » est renforcé par la sûreté considérée comme inégalable que semble offrir le vissage par rapport aux autres moyens de fermeture, par exemple le clipsage. Ces avantages supposés masquent les inconvénients du vissage dans son utilisation quotidienne : durée d'ouverture, mouvement rotatif pénible, blocage possible après plusieurs utilisations. La technologie du soufflage reste la technique la plus répandue. Pourtant, elle présente les inconvénients précités et entraîne un coût plancher qu'il semble difficile de franchir. Elle n'est que faiblement concurrencée par des techniques complexes d'injection et/ou de soudure de pièces rapportées ou serties, mais ces solutions présentent un coût sensiblement supérieur.In addition, this technique does not allow a good regularity of the thickness of the walls, which results in defects in the surface finish: "orange peel" effect linked to the escape of air. poorly controlled on blowing, or longitudinal "seam" linked to the joint plane. These defects prevent the use of certain decoration techniques, decor for example made with lithographic techniques, and generally require the implementation of finishing operations (varnish, lacquering, ...). Furthermore, one of the most important aspects concerns the sealing problems linked to the volatility of cosmetic products. Only screwing is deemed to be able to provide a sufficiently effective seal for cosmetic products, and any other closing technique is therefore a priori rejected. This "blocking" is reinforced by the safety considered to be incomparable that the screwing seems to offer compared to other means of closing, for example clipping. These supposed advantages mask the drawbacks of screwing in its daily use: opening time, painful rotary movement, blocking possible after several uses. Blowing technology remains the most widely used technique. However, it has the aforementioned drawbacks and involves a floor cost which it seems difficult to overcome. It is only weakly competed by complex techniques of injection and / or welding of inserts or crimped parts, but these solutions have a significantly higher cost.
La présente invention vise à remédier à ces inconvénients, en particulier à réaliser un emballage moins coûteux par l'utilisation de matériaux courants ou à élargir le choix des matériaux utilisables pour permettre la mise en œuvre de nouvelles formes et de nouveaux décors.: les polystyréniques, par exemple en ABS (Acrylo- Butadiène - Styrène) ou SAN (Styrène- Acrylo — Nitrile), les polyesters, par exemple le PET (Poly- Ethylène- Téréphtalate) ou PEN (Poly- Ethylène- Naphtalate), les polyoléfines tels que les PP (Poly- Propylènes) ou PE (Poly- Ethylènes) ou les acétales, tels que le POM (Poly- Oxy- Méthylène) En outre, le choix élargi des matériaux utilisables permet également d'élargir les formules des produits à utiliser, en évitant les réactions possibles tout en diminuant la perméabilité à travers les parois par migration du solvant.The present invention aims to remedy these drawbacks, in particular to produce less expensive packaging by the use of common materials or to widen the choice of materials which can be used to allow the implementation of new shapes and new decorations: polystyrenics , for example ABS (Acrylo- Butadiene - Styrene) or SAN (Styrene- Acrylo - Nitrile), polyesters, for example PET (Poly- Ethylene- Terephthalate) or PEN (Poly- Ethylene- Naphthalate), polyolefins such as PP (Poly-Propylenes) or PE (Poly-Ethylenes) or acetals, such as POM (Poly-Oxy-Methylene) In addition, the wider choice of usable materials also makes it possible to broaden the formulas of the products to be used, avoiding possible reactions while reducing permeability through the walls by migration of the solvent.
Par ailleurs, un autre but de l'invention est de mettre en œuvre une technologie aussi simple que possible. Un but additionnel de l'invention est de faciliter l' ouverture/fermeture du conditionnement tout en assurant une excellente étanchéité.Furthermore, another object of the invention is to implement a technology as simple as possible. An additional object of the invention is to facilitate the opening / closing of the packaging while ensuring excellent sealing.
La présente invention vise aussi à permettre l'intégration de tout type d'applicateurs, tels que brosse ou applicateur - mousse, et à permettre une rupture dans les habitudes d'utilisation de ce type de conditionnement en provoquant un effet de nouveauté.The present invention also aims to allow the integration of all types of applicators, such as brush or applicator - foam, and to allow a break in the habits of use of this type of packaging by causing a novelty effect.
Pour atteindre ces objectifs, l'invention propose de réaliser le moulage du récipient en une pièce par injection simple, c'est-à-dire sans soufflage.To achieve these objectives, the invention proposes to mold the container in one piece by simple injection, that is to say without blowing.
Plus précisément, l'invention a pour objet un conditionnement pour produit cosmétique, en particulier pour mascara, comportant une flaconnette présentant une ouverture associée à une capsule couplée à une tige sur laquelle est monté un applicateur. La flaconnette est réalisée par moulage par injection de matériau plastique en au moins un point à proximité de l'ouverture.More specifically, the subject of the invention is a packaging for cosmetic product, in particular for mascara, comprising a bottle having an opening associated with a capsule coupled to a rod on which an applicator is mounted. The bottle is produced by injection molding of plastic material at at least one point near the opening.
L' étanchéité est assurée par un contact circulaire radial de la capsule directement sur la flaconnette.The seal is ensured by a circular radial contact of the capsule directly on the vial.
Selon un mode de réalisation, la capsule est verrouillée par clipsage axial sur la flaconnette.According to one embodiment, the capsule is locked by axial clipping on the vial.
Dans ces conditions, l' étanchéité est obtenue par le couplage entre la flaconnette et la capsule, l'injection se faisant là où une grande précision est nécessaire pour garantir l'étanchéité. Ainsi, l'essoreur n'intervient pas dans la fonction mécanique relative à l'étanchéité. De préférence, des renflements et déformations complémentaires, réalisées par nervurage circonférentiel, réalisent le contact circulaire radial.Under these conditions, the seal is obtained by coupling between the vial and the capsule, the injection taking place where great precision is necessary to guarantee the seal. Thus, the wiper does not intervene in the mechanical function relating to the seal. Preferably, additional bulges and deformations, produced by circumferential ribbing, make the radial circular contact.
Selon des modes de réalisation particuliers :According to particular embodiments:
- le contact circulaire d'étanchéité est réalisé près de l'ouverture de la flaconnette ; - la tige et la capsule sont réalisées par injection d'un même moulage formant une pièce unique ; et- The circular sealing contact is made near the opening of the bottle; - The rod and the capsule are produced by injection of the same molding forming a single piece; and
- le matériau utilisé pour réaliser le conditionnement est pris parmi les polystyrènes, les polyoléfines, les polyesters, et les polyacétales. L'essoreur peut être réalisé en injection de manière traditionnelle, ce qui étend le choix de la matière plastique utilisée (polyéthylène (PE), polypropylène (PP) ou un élastomère) en fonction de la dureté d'essorage souhaitée. L'assemblage de l'essoreur sur la flaconnette se fait généralement par clipsage. Le conditionnement selon l'invention est en outre particulièrement adapté aux formes oblongues ou allongées, mais peut également convenir à la réalisation de formes difficilement réalisables par les procédés habituels, par exemple la forme carrée ou polygonale à angles vifs.- the material used to carry out the packaging is taken from polystyrenes, polyolefins, polyesters, and polyacetals. The wringer can be produced by injection in the traditional way, which extends the choice of plastic used (polyethylene (PE), polypropylene (PP) or an elastomer) depending on the desired spin hardness. The wiper is assembled on the bottle generally by clipping. The packaging according to the invention is also particularly suitable for oblong or elongated shapes, but may also be suitable for producing shapes which are difficult to produce by the usual methods, for example the square or polygonal shape with sharp angles.
Avantageusement, la maîtrise de l'épaisseur des parois de la flaconnette grâce à la technique de moulage par injection utilisée, permet d'améliorer sensiblement l'étanchéité par perte de poids, ainsi que la régularité des décors pouvant être réalisée sur ces parois. Le décor peut avantageusement couvrir toute la surface, par exemple par applat de teintes par l'impression de vignettes (" vignettage ") par lithographie ou par procédé offset, en intégrant différents éléments, par exemple le code barre ou au moins une fenêtre sans décor lorsque le matériau est transparent, pour visualiser la teinte du produit contenu dans le flacon.Advantageously, the control of the thickness of the walls of the vial thanks to the injection molding technique used, makes it possible to substantially improve the seal by weight loss, as well as the regularity of the decorations which can be produced on these walls. The decoration can advantageously cover the entire surface, for example by applying hues by printing vignettes ("vignetting") by lithography or by offset process, by integrating different elements, for example the bar code or at least one window without decoration. when the material is transparent, to visualize the color of the product contained in the bottle.
Il est également avantageux de personnaliser le conditionnement à l'usine, avant remplissage, en fonction de certains critères (la teinte, la formule ou les informations dans la langue du pays) et de commander alors la quantité désirée à partir d'une seule référence.It is also advantageous to customize the packaging in the factory, before filling, according to certain criteria (the shade, the formula or the information in the language of the country) and then order the desired quantity from a single reference .
L'invention sera mieux comprise et d'autres caractéristiques et avantages ressortiront de la description détaillée ci-après d'exemples de réalisation, en référence aux figures annexées qui représentent, respectivement : - la figure 1 , une vue de face d'une flaconnette conforme à l'invention ;The invention will be better understood and other characteristics and advantages will emerge from the detailed description below of exemplary embodiments, with reference to the appended figures which represent, respectively: - Figure 1, a front view of a bottle according to the invention;

- les figures 4 et 4a, une vue en coupe longitudinale du même ensemble et une partie agrandie de cette coupe.- Figures 4 and 4a, a longitudinal sectional view of the same assembly and an enlarged part of this section.
Sur les figures, on a utilisé les mêmes références pour désigner des éléments identiques ou correspondants.In the figures, the same references have been used to designate identical or corresponding elements.
Ainsi qu'il apparaît sur la figure 1 , un exemple de flaconnette selon l'invention se présente sous la forme d'un tube allongé 1 , sensiblement cylindrique autour d'un axe X'X. Le tube 1 contient un produit cosmétique, du mascara dans l'exemple de réalisation. Une partie d'extrémité fermée 10 du tube est formée d'une calotte sensiblement sphérique qui se prolonge par un corps cylindrique 11 de diamètre externe égal à 14 mm. Ce corps cylindrique 11 se prolonge par un autre corps cylindrique 12 d'extrémité ouverte 14, et de diamètre externe légèrement inférieur, égal à 12,5 mm dans cet exemple. Ce tube 12 présente un contact circulaire par un renflement radial 13, de diamètre externe maximal égal à environ 13 mm. Ce renflement 13 forme nervure pour définir une zone de clipsage pour la capsule décrite ci-après.As it appears in FIG. 1, an example of a vial according to the invention is in the form of an elongated tube 1, substantially cylindrical around an axis X'X. Tube 1 contains a cosmetic product, mascara in the exemplary embodiment. A closed end portion 10 of the tube is formed of a substantially spherical cap which is extended by a cylindrical body 11 with an external diameter equal to 14 mm. This cylindrical body 11 is extended by another cylindrical body 12 of open end 14, and of slightly smaller external diameter, equal to 12.5 mm in this example. This tube 12 has a circular contact by a radial bulge 13, of maximum external diameter equal to about 13 mm. This bulge 13 forms a rib to define a clipping zone for the capsule described below.
La figure 2 illustre, en vue de face, une capsule creuse 2 de révolution autour d'un axe qui se confond avec l'axe X'X de la flaconnette 1 après montage, la capsule creuse étant couplée à une tige 20 centrée également autour du même axe. Sur cette tige 20, est montée une brosse 21 , apte à recueillir le mascara contenu dans la flaconnette. Lorsque la capsule 2 est clipsée sur la flaconnette 1 , l'ensemble présente l'aspect illustré à la figure 3. Les surfaces externes de la capsule 2 et de la flaconnette 1, présentant des formes de type cylindrique ou quasi - cylindrique, assurent avantageusement une quasi - continuité de courbure dans la zone de couplage externe Z1.FIG. 2 illustrates, in front view, a hollow capsule 2 of revolution about an axis which merges with the axis X'X of the bottle 1 after assembly, the hollow capsule being coupled to a rod 20 also centered around of the same axis. On this rod 20, a brush 21 is mounted, suitable for collecting the mascara contained in the bottle. When the capsule 2 is clipped onto the vial 1, the assembly has the appearance illustrated in FIG. 3. The external surfaces of the capsule 2 and of the vial 1, having shapes of the cylindrical or quasi-cylindrical type, ensure advantageously a quasi-curvature continuity in the external coupling zone Z1.
Comme il ressort de la vue en coupe du même ensemble capsule-flaconnette, telle qu'illustrée à la figure 4, la capsule 2 et la tige 20 sont formées d'une seule pièce venue de moulage. Le clipsage de la capsule 2 sur la flaconnette 1 est réalisé comme illustré plus précisément sur l'agrandissement de la figure 4a, à partir du bossage 13 qui coopère avec une rainure 22 et un bossage 23 formés sur la face interne 2i de la capsule 2. Afin d'assurer une bonne étanchéité pour éviter l'évaporation du mascara, la face interne 2i de la capsule 2 présente également un deuxième bossage annulaire 24, disposé près de l'extrémité ouverte 14 de la flaconnette 1. L'épaisseur de ce bossage 24 est réglée pour que la surface de contact du bossage vienne en appui serré contre la face externe 1e de la flaconnette 1. Toutes les pièces constituant le conditionnement selon l'invention, à savoir la flaconnette, la capsule, la tige et l'essoreur, sont réalisées par moulage par injection, sans soufflage. Un tel procédé permet à partir de buses d'injection de former dans des moules adaptés, et à des températures correspondant à la matière plastique utilisée, des pièces en matière plastique. Afin de rentabiliser ce type de moulage, il est réalisé simultanément un nombre de pièces adaptées, par exemple 24, selon la réalisation du moule.As emerges from the sectional view of the same capsule-flask assembly, as illustrated in FIG. 4, the capsule 2 and the rod 20 are formed in one piece from molding. The clipping of the capsule 2 on the bottle 1 is carried out as illustrated more precisely on the enlargement of FIG. 4a, from the boss 13 which cooperates with a groove 22 and a boss 23 formed on the internal face 2i of the capsule 2 In order to ensure a good seal to avoid the evaporation of the mascara, the internal face 2i of the capsule 2 also has a second annular boss 24, disposed near the open end 14 of the bottle 1. The thickness of this boss 24 is adjusted so that the contact surface of the boss presses tightly against the outer face 1e of the vial 1. All the parts constituting the packaging according to the invention, namely the vial, the capsule, the rod and the wringer, are produced by injection molding, without blowing. Such a process makes it possible, from injection nozzles, to form plastic parts, in suitable molds, and at temperatures corresponding to the plastic material used. In order to make this type of molding profitable, a number of suitable parts, for example 24, are produced simultaneously, depending on the production of the mold.
Les points d'injection à l'extrémité des buses orientées sont avantageusement répartis régulièrement et radialement au niveau d'une extrémité du moule correspondant à une zone dont l'épaisseur doit être rigoureusement calibrée, par exemple lorsque, comme dans le cas présent, cette zone critique correspond à une zone d'étanchéité. A l'autre extrémité, le moule fermé présente un point d'évent pour l'évacuation de l'air contenu dans le moule. Lors du refroidissement, la rétractation de matériau se produit alors du côté opposé à la zone d'injection, c'est-à-dire loin de la zone critique. Les matériaux utilisés pour la flaconnette et la capsule-tige sont, dans l'exemple de réalisation, le PP ou le POM, et pour l'essoreur le PEBD (Polyéthylène butadiène).The injection points at the end of the oriented nozzles are advantageously distributed regularly and radially at one end of the mold corresponding to an area whose thickness must be rigorously calibrated, for example when, as in the present case, this critical zone corresponds to a sealing zone. At the other end, the closed mold has a vent point for the evacuation of the air contained in the mold. During cooling, the shrinkage of material then occurs on the side opposite the injection zone, that is to say far from the critical zone. The materials used for the vial and the stem cap are, in the embodiment, PP or POM, and for the wringer PEBD (Polyethylene butadiene).
Avantageusement, les tiroirs d'ouverture du moule pour démouler la carotte formée lors de l'injection, permet de réaliser la nervure radiale d'étanchéité. Dans ces conditions, les retassures formées par le retrait du matériau utilisé lors du refroidissement, ne se forment pas du côté des zones d'étanchéité et d'assise de l'essoreur. Advantageously, the mold opening drawers for demolding the core formed during the injection makes it possible to produce the radial sealing rib. Under these conditions, the recesses formed by the withdrawal of the material used during cooling, do not form on the side of the sealing and seating areas of the wiper.
