Description

CONDITIONNEMENT ETANCHE POUR PRODUIT COSMETIQUE WATERPROOF PACKAGING FOR COSMETIC PRODUCTS
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 en matériau souple 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 a cosmetic product, such as mascaras, eyeshadows, lip glosses or highlighters, usually consists of an open vial provided with a wringer in flexible material and with a capsule on which is fixed a rod terminated by an applicator to apply the product contained in the bottle, for example a brush or comb of mascara, 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 wringer, extending radially, comes into contact with the applicator to remove the excess product.
L'un des aspects les plus importants concerne les problèmes d' étanchéité liés à la volatilité des produits cosmétiques.One of the most important aspects concerns the sealing problems linked to the volatility of cosmetic products.
Pour obtenir cette étanchéité, par exemple dans le cas d'un verrouillage par vissage, il est connu de l'état de la technique une solution ainsi qu'une variante de cette solution, telles qu'illustrées respectivement aux figures 1 et 1a (agrandissement) d'une part, et aux figures 2 et 2a (agrandissement) d'autre part. Dans les deux cas, la capsule 2 est vissée sur le col de la flaconnette 1 par filetage hélicoïdal 100 selon l'axe longitudinal X'X.To obtain this seal, for example in the case of screw locking, it is known from the prior art a solution as well as a variant of this solution, as illustrated respectively in FIGS. 1 and 1a (enlargement ) on the one hand, and Figures 2 and 2a (enlargement) on the other hand. In both cases, the capsule 2 is screwed onto the neck of the bottle 1 by helical thread 100 along the longitudinal axis X'X.
Selon l'état de la technique, l'étanchéité est assurée entre la capsule 2 et le col de la flaconnette 1 par l'intermédiaire de l'essoreur 3 qui est habituellement utilisé en tant que joint du fait de sa souplesse. La déformation de l'essoreur 3 est axiale et essentiellement localisée (force axiale F^ sur la nervure périphérique 4 de la capsule. Cependant, le vissage n'est efficace que si la force de verrouillage est suffisamment élevée. Dans ces conditions, les surfaces de contact relativement complexes S1 et S2, entre la capsule 2 et l'essoreur 3, et entre l'essoreur 3 et le col de la flaconnette 1 , génèrent des fuites de solvant par capillarité. En outre, un serrage trop vigoureux détériore la portée des contacts par déformation permanente (fluage de la matière plastique) : l'efficacité des fermetures ultérieures est dégradée.According to the state of the art, the seal is ensured between the capsule 2 and the neck of the bottle 1 by means of the wiper 3 which is usually used as a seal due to its flexibility. The deformation of the wiper 3 is axial and essentially localized (axial force F ^ on the peripheral rib 4 of the capsule. However, tightening is only effective if the locking force is high enough. Under these conditions, the relatively complex contact surfaces S1 and S2, between the capsule 2 and the wiper 3, and between the wiper 3 and the neck of the bottle 1, generate solvent leaks by capillary action. In addition, overly vigorous tightening deteriorates the contact range by permanent deformation (creep of the plastic): the effectiveness of subsequent closings is degraded.
La variante, illustrée par les vues en coupe des figures 2 et 2a, permet de multiplier la force de contact entre la capsule 2 et l'essoreur 3 par la forme en cône de la tête de tige 20 de la capsule. Cet effet de cône permet d'assurer une étanchéité par un effort de serrage moindre que dans le cas précédent, mais l'effet de cône induit une déformation radiale (composante Fr de la force de contact F2) de l'ensemble essoreur - col de flaconnette, qui s'accroît fortement jusqu'à perturber le fonctionnement du filetage, suite aux ouvertures et fermetures répétées effectuées par l'utilisateur. Les surfaces S2 et S3 de fuite par capillarité restent aussi importantes et la déformation par fluage de la matière plastique est accélérée.The variant, illustrated by the sectional views of FIGS. 2 and 2a, makes it possible to multiply the contact force between the capsule 2 and the wiper 3 by the cone shape of the rod head 20 of the capsule. This cone effect makes it possible to ensure a seal by a lower clamping force than in the previous case, but the cone effect induces a radial deformation (component F r of the contact force F 2 ) of the wringer assembly - bottle neck, which increases sharply until disturbing the functioning of the thread, following repeated openings and closings carried out by the user. The capillary leakage surfaces S2 and S3 also remain large and the creep deformation of the plastic material is accelerated.
De plus, ces solutions connues imposent un jeu axial Z non négligeable et inesthétique entre l'extrémité de la capsule 2 et l'épaulement du col de flaconnette 1. Ce jeu est fonctionnel et permet d'assurer une sécurité de portée entre le joint essoreur et la capsule.In addition, these known solutions impose a non-negligible and unaesthetic axial clearance Z between the end of the capsule 2 and the shoulder of the bottle neck 1. This clearance is functional and makes it possible to ensure a safety of range between the wiper seal. and the capsule.
Par ailleurs, 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 « préjugé » est renforcé par la sûreté de fermeture considérée comme inégalable que semble offrir le vissage par rapport aux autres moyens de fermeture. Ces avantages supposés masquent les inconvénients du vissage dans son utilisation quotidienne : durée d'ouverture, mouvement rotatif pénible, blocage possible après plusieurs utilisations. Un but de l'invention est d'assurer une excellente étanchéité du conditionnement.Furthermore, only the 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 "prejudice" is reinforced by the safety of closing considered as incomparable that the screwing seems to offer compared to the other means of closing. These supposed advantages mask the drawbacks of screwing in its daily use: opening time, painful rotary movement, blocking possible after several uses. An object of the invention is to ensure excellent sealing of the packaging.
Plus précisément, l'invention a pour objet un conditionnement pour produit cosmétique, en particulier pour mascara, comportant une flaconnette sur laquelle est monté un essoreur, la flaconnette présentant un col débouchant sur une ouverture, et une capsule couplée à une tige sur laquelle est montée une brosse. L'étanchéité de ce conditionnement est assurée par contact annulaire radial de la capsule directement sur le col de la flaconnette.More specifically, the subject of the invention is a packaging for cosmetic product, in particular for mascara, comprising a small bottle on which a wringer is mounted, the small bottle having a neck opening onto an opening, and a capsule coupled to a rod on which is mounted a brush. The sealing of this packaging is ensured by radial annular contact of the capsule directly on the neck of the bottle.
Selon des modes de réalisation particuliers :According to particular embodiments:
- le contact annulaire radial est effectué entre un nervurage circonférentiel de la capsule et une zone cylindrique du col de flaconnette, dont les qualités de surface sont réglées ;the radial annular contact is made between a circumferential ribbing of the capsule and a cylindrical region of the bottle neck, the surface qualities of which are regulated;
- les moyens de verrouillage entre la capsule et la flaconnette sont dissociés de la zone d' étanchéité du col de la flaconnette.- The locking means between the capsule and the bottle are separated from the sealing area of the neck of the bottle.
Dans ces conditions, la jonction capsule/flaconnette est avantageusement localisée sur des surfaces de géométrie simple entre le nervurage circonférentiel et la zone cylindrique.Under these conditions, the capsule / vial junction is advantageously located on surfaces of simple geometry between the circumferential ribbing and the cylindrical zone.
Les forces de contact, générées par un ajustement serré entre les surfaces d'étanchéité, sont dissociées et indépendantes des contraintes exercées sur l'organe de verrouillage. Ainsi, tout relâchement lié au fluage de la matière plastique au niveau du verrouillage n'a pas d'incidence sur les performances d'étanchéité.The contact forces, generated by a tight fit between the sealing surfaces, are dissociated and independent of the stresses exerted on the locking member. Thus, any loosening linked to the creep of the plastic material at the level of the locking has no effect on the sealing performance.
La qualité de la jonction peut être optimisée par un travail de finition sur les moules, notamment sur la précision dimensionnelle, la géométrie et l'état de surface des parties moulantes se rapportant au nervurage circonférentiel de la capsule et à la zone cylindrique du col de la flaconnette. En particulier, tout élément technique qui induit des irrégularités de surface, tel que plan de joint, éjecteur, évent, etc., est exclu sur ces parties moulantes. De plus, les forces de contact d'étanchéité étant radiales, elles induisent une conformation des surfaces de contact l'une sur l'autre, sans composante axiale qui tendrait au contraire à séparer la capsule de la flaconnette.The quality of the junction can be optimized by finishing work on the molds, in particular on the dimensional precision, the geometry and the surface condition of the molding parts relating to the circumferential ribbing of the capsule and to the cylindrical zone of the neck of the bottle. In particular, any technical element which induces surface irregularities, such as joint plane, ejector, vent, etc., is excluded on these molding parts. In addition, the sealing contact forces being radial, they induce a conformation of the contact surfaces one on the other, without axial component which would on the contrary tend to separate the capsule from the vial.
Un tel effet de conformation permet également d'égaliser les micro-irrégularités de surface et de stabiliser les efforts, tout en compensant les tolérances dimensionnelles de production. Cet effet peut être avantageusement renforcé par un sur-ajustement du serrage du diamètre de nervurage sur le diamètre du col de la flaconnette, en tenant compte de la dureté du matériau et de sa résistance au fluage.Such a shaping effect also makes it possible to equalize the micro-irregularities of the surface and to stabilize the forces, while compensating for the dimensional tolerances of production. This effect can be advantageously reinforced by an over-adjustment of the tightening of the ribbing diameter on the diameter of the neck of the bottle, taking into account the hardness of the material and its resistance to creep.
Ainsi, les fuites par capillarité sont fortement réduites, voire éliminées, et la jonction flaconnette - capsule bénéficie d'une tolérance d'ajustement suffisante pour supprimer tout jeu inesthétique entre la capsule et l'épaulement du col de la flaconnette. De plus, cette tolérance permet d'aligner par vissage la capsule sur la flaconnette de manière à ajuster une forme particulière, telle que carrée, polygonale, ovale, etc., de ces pièces.Thus, leaks by capillarity are greatly reduced, or even eliminated, and the junction between the vial and the capsule has sufficient adjustment tolerance to eliminate any unsightly play between the capsule and the shoulder of the neck of the vial. In addition, this tolerance makes it possible to align by screwing the capsule on the vial so as to adjust a particular shape, such as square, polygonal, oval, etc., of these parts.
Le verrouillage entre la capsule et la flaconnette peut être réalisé soit classiquement par vissage, soit par clipsage axial de la capsule sur , la flaconnette pour faciliter le verrouillage/déverrouillage du conditionnement. Le vissage et le clipsage sont réalisés hors des surfaces d'étanchéité selon l'invention.The locking between the cap and the vial can be done either conventionally by screwing or by axial clipping the cap on the vial to facilitate locking / unlocking of the package. The screwing and clipping are carried out outside the sealing surfaces according to the invention.
Afin d'élaborer la mise en place du bon niveau d'étanchéité prévue ci-dessus, l'invention concerne également la technique de fabrication du conditionnement. Classiquement, une flaconnette de ce type est réalisée par injection/soufflage ou extrusion/soufflage. Or le soufflage impose certains types de forme " soufflables " et peut donc limiter la composition chimique des plastiques à ceux qui présentent une transition vitreuse, par exemple le polypropylène ou le polyéthylène. Un autre but de l'invention est de remédier à ces inconvénients, en particulier elle vise à obtenir un état de surface supérieur là où une grande précision est nécessaire pour l' étanchéité.In order to develop the establishment of the correct level of tightness provided above, the invention also relates to the packaging manufacturing technique. Conventionally, a bottle of this type is produced by injection / blowing or extrusion / blowing. However, blowing imposes certain types of "blown" shape and can therefore limit the chemical composition of plastics to those which have a glass transition, for example polypropylene or polyethylene. Another object of the invention is to remedy these drawbacks, in particular it aims to obtain a higher surface finish where great precision is required for sealing.
Réaliser un emballage moins coûteux par l'utilisation de matériaux courants ou élargir le choix des matériaux utilisables pour permettre la mise en œuvre de nouvelles formes et de nouveaux décors est également un objectif de l'invention, en particulier : 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.Producing less expensive packaging by using common materials or widening the choice of materials that can be used to allow the implementation of new shapes and new decorations is also an objective of the invention, in particular: polystyrenics, for example in ABS (Acrylo-Butadiene-Styrene) or SAN (Styrene-Acrylo-Nitrile), polyesters, for example PET (Poly-Ethylene-Terephthalate) or PEN (Poly-Ethylene-Naphtalate), 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 widen 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.Furthermore, another object of the invention is to implement a technology as simple as possible.
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 everything. type 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 en une pièce par la technique soit du soufflage simple, en particulier extrusion/soufflage ou injection/soufflage, soit par injection simple de matériau plastique, c'est-à-dire sans soufflage, en au moins un point situé hors de la zone d'étanchéité mais, avantageusement, au plus près de l'ouverture de la flaconnette. Dans ces conditions, le procédé d'injection garantit la meilleure précision possible à la zone d'étanchéité.To achieve these objectives, the invention proposes to carry out molding in one piece by the technique of either simple blowing, in particular extrusion / blowing or injection / blowing, or by simple injection of plastic material, that is to say without blowing, at at least one point located outside the sealing zone but, advantageously, as close as possible to the opening of the vial. Under these conditions, the injection process guarantees the best possible precision in the sealing zone.
Selon des modes de réalisation particuliers : - la tige et la capsule sont réalisées par injection d'un même moulage formant une pièce unique ; etAccording to particular embodiments: - 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.- the material used to carry out the packaging is taken from polystyrenes, polyolefins, polyesters, and polyacetals.
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.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.
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. La continuité de toute forme entre la capsule et la flaconnette est alors conservée par l'ajustement de la capsule sur la flaconnette, que ce soit par vissage ou par clipsage.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. The continuity of any shape between the capsule and the small bottle is then preserved by adjusting the capsule on the small bottle, whether by screwing or by clipping.
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. 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 :It is also advantageous to customize the packaging at 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 . 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:

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 3, 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.As it appears in FIG. 3, 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.
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 approximativement égal à 13 mm. Ce renflement 13 forme nervure pour définir une zone de clipsage pour la capsule décrite ci-après.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 approximately 13 mm. This bulge 13 forms a rib to define a clipping zone for the capsule described below.
La figure 4 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 5. 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. 4 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 bottle 1, the assembly has the appearance illustrated in FIG. 5. The external surfaces of the capsule 2 and of the bottle 1, having shapes of the cylindrical or quasi-cylindrical type, advantageously ensure almost continuous curvature 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 6, 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 6a, 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.As is apparent from the sectional view of the same capsule-flask assembly, as illustrated in FIG. 6, 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. 6a, from the boss 13 which cooperates with a groove 22 and a boss 23 formed on the internal face 2i of the capsule 2 .
Afin d'assurer /'étanchéité pour éviter l'évaporation du mascara, la face interne 2i de la capsule 2 présente un 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.In order to ensure the seal to prevent evaporation of the mascara, the internal face 2i of the capsule 2 has an 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 comes to press tightly against the external face 1e of the vial 1.
Selon une variante de réalisation, la capsule et la tige sont formées de deux pièces assemblées ou solidarisées (soudage, collage, etc.). La capsule coopère avec la tige par leurs surfaces de contact qui assurent un montage resserré de la tige dans la capsule en réalisant une extrémité de tige de diamètre externe très légèrement supérieur au diamètre interne de la capsule au niveau de la zone de contact. Comme illustré sur la vue en coupe de la figure 7, et partiellement agrandie en figure 7a, l'invention n'est pas limitée au verrouillage par clipsage. Dans cet exemple, le verrouillage est réalisé par vissage traditionnel 100.According to an alternative embodiment, the capsule and the rod are formed from two assembled or joined parts (welding, bonding, etc.). The capsule cooperates with the rod by their contact surfaces which ensure a tight mounting of the rod in the capsule by producing a rod end with an external diameter very slightly greater than the internal diameter of the capsule at the level of the contact zone. As illustrated in the sectional view of Figure 7, and partially enlarged in Figure 7a, the invention is not limited to locking by clipping. In this example, the locking is achieved by traditional screwing 100.
Le contact annulaire radial d'étanchéité est réalisé par le bossage annulaire 24 de la capsule qui prend contact, en ajustement serré, sur une zone cylindrique 101 , présentant un état de surface de haute précision, et formant la partie supérieure du col 12 de la flaconnette 1. Du fait que le contact d'étanchéité est exercé de manière radiale (force F3), les surfaces de contact se conforment l'une sur l'autre sans subir de déformations axiales.The radial sealing annular contact is produced by the annular boss 24 of the capsule which makes contact, in close fit, on a cylindrical region 101, having a high precision surface condition, and forming the upper part of the neck 12 of the flask 1. Because the sealing contact is exerted radially (force F 3 ), the contact surfaces conform to one another without undergoing axial deformations.
La jonction flaconnette - capsule S4 est maîtrisée avec précision, sans jeu, du fait de la tolérance offerte par la largeur de la zone 101 sur laquelle se règle l' étanchéité.The junction between bottle and capsule S4 is precisely controlled, without play, because of the tolerance offered by the width of the zone 101 on which the sealing is adjusted.
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 moulage, il est réalisé simultanément un nombre de pièces adaptées, par exemple 24, à partir de tiroirs dans lesquels sont disposés les moules.All the parts constituting the packaging according to the invention, namely the flask, 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 from drawers in which the molds are arranged.
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 de l'introduction du mandrin. 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.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 the introduction of the mandrel. During cooling, the shrinkage of material then occurs on the side opposite the injection zone, that is to say far from the critical zone.
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 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.
