Description

BOÎTIER ULTRA-PLAT POUR ENCART ULTRA-FLAT INSERT BOX
L'invention se rapporte à un boîtier ultra-plat pour encart dans les journaux ou autres revues de la presse grand public ou spécialisée, un tel boîtier contenant un échantillon de produit de type pâteux coulé, volatil ou non, cosmétique ou alimentaire.The invention relates to an ultra-flat box for inserting in newspapers or other magazines of the general or specialized press, such a box containing a sample of a pasty type product poured, volatile or not, cosmetic or food.
Afin de réaliser des enveloppes contenant des produits pour être insérés comme encarts dans la presse, des sachets formés de deux feuilles soudées en périphérie sont habituellement utilisés. Ces feuilles, constituées d'un matériau composite multicouche - aluminium, polyéthylène, polyester -, ne peuvent pas contenir de produits pâteux coulés, mais seulement une fine pellicule de liquide ou de fluide.In order to produce envelopes containing products to be inserted as inserts in the press, bags formed from two sheets welded at the periphery are usually used. These sheets, made of a multilayer composite material - aluminum, polyethylene, polyester - cannot contain pasty poured products, but only a thin film of liquid or fluid.
En effet, les conteneurs doivent satisfaire à certains critères pour être acceptés comme encart, notamment ils doivent pouvoir résister à une pression importante provoquée par le poids des empilements (réalisés sur des palettes) dans les zones de stockage ou pendant le transport. Les sociétés de distribution exigent en général une résistance à une charge de 15 000 N, appliquée pendant 6 secondes sur la face supérieure, cette charge ne devant entraîner ni fuite ni éclatement des conteneurs, afin de ne pas risquer de souiller les marchandises. II existe des revêtements en micro-encapsulation contenant quelques gouttes de parfum dont l'odeur diffuse après déchirure du revêtement. Cependant, les micro-encapsulations ne permettent pas de contenir de produits pâteux coulés en quantité suffisante.In fact, the containers must meet certain criteria to be accepted as an insert, in particular they must be able to withstand significant pressure caused by the weight of the stacks (made on pallets) in the storage areas or during transport. Distribution companies generally require a resistance to a load of 15,000 N, applied for 6 seconds on the upper face, this load must not cause the containers to leak or burst, so as not to risk contaminating the goods. There are coatings in micro-encapsulation containing a few drops of perfume whose diffuse odor after tearing of the coating. However, micro-encapsulations do not make it possible to contain pasty products poured in sufficient quantity.
Par ailleurs, il existe aussi des dépôts de couches très fines en sérigraphie d'un produit cosmétique tel que fond de teint ou rouge à lèvres, recouvert d'une pellicule de protection. Cette solution ne permet pas là encore de présenter un produit pâteux coulé en quantité suffisante ou un produit ayant une forte volatilité.In addition, there are also deposits of very thin layers in screen printing of a cosmetic product such as foundation or lipstick, covered with a protective film. This solution again does not make it possible to present a pasty product poured in sufficient quantity or a product having a high volatility.
Il est également connu, par exemple, par le brevet JP-A- 91/73137, l'utilisation d'une plaque de plastique perforée et emboutie, munie éventuellement d'une entretoise, fermée par deux films de plastique souple. De telles solutions sont d'un coût économique élevé, et la pluralité de surfaces collées ou soudées multiplie les risques de fuites ou d'éclatement.It is also known, for example, from patent JP-A-91/73137, the use of a perforated and stamped plastic plate, optionally provided with a spacer, closed by two flexible plastic films. Such solutions are of high economic cost, and the plurality of glued or welded surfaces increases the risk of leaks or bursting.
L'invention vise à remédier aux inconvénients de l'Etat de la Technique, et en particulier, à réaliser un boîtier ultra-plat pour encart de presse, permettant de résister à la pression mécanique d'au moins 15 000 N et présentant une épaisseur inférieure à environ 2 mm, tout en permettant d'accueillir un produit pâteux coulé en quantité suffisante pour permettre d'en apprécier la texture ou de l'utiliser sous forme de test, avec un coût économique raisonnable. Pour ce faire, l'invention propose de combiner un boîtier en matière thermopiastique présentant un rebord périphérique sur lequel un film de fermeture est soudé.The invention aims to remedy the drawbacks of the state of the art, and in particular, to produce an ultra-flat box for press insert, making it possible to withstand the mechanical pressure of at least 15,000 N and having a thickness of less than about 2 mm, while making it possible to accommodate a pasty product poured in sufficient quantity to allow its texture to be appreciated or to be used in the form of a test, with reasonable economic cost. To do this, the invention proposes to combine a housing made of thermopiastic material having a peripheral rim on which a closure film is welded.
Plus précisément, l'invention a pour objet un boîtier ultra-plat pour encart comportant un logement apte à accueillir un produit pâteux coulé avec une hauteur hors tout du boîtier à environ 2 mm, dans lequel le logement est limité par un fond et un flanc latéral interne d'une bordure périphérique surélevée par rapport au fond qui présente une face supérieure et une face d'appui planes et parallèles ; la bordure présente une surface supérieure sensiblement parallèle au fond pour accueillir par soudure un opercule formé d'une fine pellicule qui recouvre le logement du boîtier et vient se souder sur la surface supérieure de la bordure, et dans lequel les dimensions radiales relatives de la bordure du boîtier en matériau thermoplastique sont proportionnées pour résister à une pression mécanique au moins égale à 15 000 N environ répartie sur sa surface. En plus de son aspect décoratif, le boîtier conforme à la présente invention présente une rigidité autorisant le conditionnement de produits fragiles, tels que les pâtes ou émulsions et il permet d'augmenter la visibilité d'une page publicitaire lorsqu'il est inséré dans une revue. En effet, la rigidité du boîtier produit un effet "marque-page" qui incite le lecteur à ouvrir la revue directement à l'emplacement de l'encart publicitaire. Les sachets traditionnels, constitués d'enveloppes souples, sont beaucoup moins efficaces dans ce but.More specifically, the subject of the invention is an ultra-flat housing for inserts comprising a housing capable of accommodating a pasty product poured with an overall height of the housing of approximately 2 mm, in which the housing is limited by a bottom and a sidewall internal lateral of a peripheral border raised relative to the bottom which has an upper face and a plane and parallel bearing face; the border has an upper surface substantially parallel to the bottom to receive by welding a cover formed of a thin film which covers the housing of the housing and is welded to the upper surface of the border, and in which the relative radial dimensions of the border of the housing made of thermoplastic material are proportioned to withstand a mechanical pressure at least equal to approximately 15,000 N distributed over its surface. In addition to its decorative appearance, the box according to the present invention has a rigidity allowing the packaging of fragile products, such as pastes or emulsions and it makes it possible to increase the visibility of an advertising page when it is inserted in a review. Indeed, the rigidity of the case produces a "bookmark" effect which encourages the reader to open the magazine directly at the location of the advertising insert. Traditional bags, made of flexible envelopes, are much less effective for this purpose.
Selon des modes de réalisation particuliers :According to particular embodiments:
- le matériau thermoplastique est injecté pour obtenir par moulage la forme souhaitée, ce matériau pouvant être du PP (polypropylène), du PE (polyéthylène), du PET (polyéthylène téréphtalate) ou de l'ABS (acrylo- butadiène-styrène) ;- The thermoplastic material is injected to obtain by molding the desired shape, this material can be PP (polypropylene), PE (polyethylene), PET (polyethylene terephthalate) or ABS (acrylobutadiene-styrene);
- l'opercule de fermeture est en matériau composite multicouche, comportant au moins une couche de matériau thermoplastique, tel que par exemple du PE ou du PP, pour permettre la soudure, et une couche "barrière" qui peut être constituée d'aluminium, pour s'opposer à la perméabilité du matériau thermoplastique ;the closure cover is made of multilayer composite material, comprising at least one layer of thermoplastic material, such as for example PE or PP, to allow the welding, and a "barrier" layer which can be made of aluminum, to oppose the permeability of the thermoplastic material;
- la bordure présente en coupe transversale une forme de pont, avec une couronne reposant sur un pilier de liaison intégré au fond du boîtier, et un pilier externe formant rebord, ce rebord présentant une face supérieure surélevée par rapport à la face supérieure de soudure de la couronne, de sorte que, après soudure, la face supérieure du rebord et celle de l'opercule affleurent ;- The border has a cross-section in the form of a bridge, with a crown resting on a connecting pillar integrated into the bottom of the housing, and an external pillar forming a rim, this rim having an upper face raised relative to the upper welding face of the crown, so that, after welding, the upper face of the rim and that of the cover are flush;
- la face supérieure de soudure de l'opercule est munie de cordons circulaires pour faciliter cette soudure, et des orifices transversaux sont répartis le long de la bordure afin de permettre une aspiration pour maintenir l'opercule avant sa soudure ;- The upper welding face of the cover is provided with circular beads to facilitate this welding, and transverse orifices are distributed along the edge in order to allow aspiration to maintain the cover before it is welded;
- la soudure de l'opercule peut être obtenue par voie thermique, par ultrasons ou par induction, la couche de PE ou de PP étant alors mise en fusion pour coller au matériau thermoplastique du boîtier ;- The sealing of the cover can be obtained thermally, by ultrasound or by induction, the layer of PE or PP then being melted to stick to the thermoplastic material of the housing;
- le fond du boîtier a une épaisseur comprise entre 0,3 et 1 mm et le flanc interne peut être incliné d'un angle d'environ 10 degrés en s' évasant en direction du fond dans le but de retenir le produit pâteux dans le cas où son adhérence sur le plastique ne serait pas suffisante pour le maintenir en place ;- the bottom of the housing has a thickness of between 0.3 and 1 mm and the internal flank can be inclined at an angle of about 10 degrees while flaring towards the bottom in order to retain the pasty product in the if its adhesion to the plastic is not sufficient to keep it in place;
- la hauteur hors tout de la bordure est comprise entre environ 1 ,5 et 2 mm ;- the overall height of the border is between approximately 1.5 and 2 mm;
- le fond du boîtier peut également présenter un relief, par exemple des stries capillaires, destiné à forcer le produit à se répartir sur toute la surface du fond du boîtier lors du coulage ;- The bottom of the case may also have a relief, for example capillary streaks, intended to force the product to be distributed over the entire surface of the bottom of the case during pouring;
- il est possible d'augmenter la mouillabilité de la matière plastique par l'ajout d'un additif (agent mouillant) dans la matière, par un traitement de surface destiné à changer la tension superficielle (agent tensio- actif) ou un traitement électrique (corona, plasma) ou une oxydation superficielle par exemple par flammage ; ces opérations, destinées à améliorer le remplissage, ont une incidence sur la qualité du produit et aussi sur son coût de revient car elles permettent d'accélérer l'opération de coulage sur la machine, tout en assurant un bon étalement du produit pâteux même dans le cas d'une couche de pâte très mince ; un effet décoratif peut être obtenu à la surface du produit car, du fait de la faible épaisseur du produit pâteux, une gravure sur le fond, éventuellement informative, tel qu'un logo ou un texte, est transmise à la surface du produit, soit par transparence si le produit pâteux n'est pas totalement opaque, soit par "ombrage" de la surface si le produit est totalement opaque. Le boîtier peut contenir tout type de produits volatils ou non volatils, tels que les produits cosmétiques, par exemple rouge à lèvres ou fond de teint, ou des produits alimentaires se présentant sous une forme pâteuse et coulée.- it is possible to increase the wettability of the plastic by adding an additive (wetting agent) in the material, by a surface treatment intended to change the surface tension (surface-active agent) or an electrical treatment (corona, plasma) or a surface oxidation, for example by flaming; these operations, intended to improve filling, have an impact on the quality of the product and also on its cost price because they make it possible to speed up the casting operation on the machine, while ensuring good spreading of the pasty product even in the case of a very thin layer of dough; a decorative effect can be obtained on the surface of the product because, due to the small thickness of the pasty product, an engraving on the bottom, possibly informative, such as a logo or a text, is transmitted to the surface of the product, either by transparency if the pasty product is not completely opaque, or by "shading" of the surface if the product is completely opaque. The housing can contain any type of volatile or non-volatile products, such as cosmetic products, for example lipstick or foundation, or food products in a pasty and poured form.
La présente invention présente également l'avantage d'autoriser le conditionnement de produits fragiles, tels que pâtes ou émulsions, du fait de la rigidité obtenue. Elle favorise également l'accès direct à la page correspondant à l'emplacement du présent boîtier dans la revue, car sa rigidité produit un effet « marque-page » supérieur à celui provoqué par les sachets traditionnels, constitués d'enveloppes souples. D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description qui suit, relatives à un exemple de réalisation, en référence aux figures annexées qui représentent respectivement :The present invention also has the advantage of allowing the packaging of fragile products, such as pastes or emulsions, due to the rigidity obtained. It also promotes direct access to the page corresponding to the location of the present case in the magazine, because its rigidity produces a "bookmark" effect greater than that caused by traditional sachets, made of flexible envelopes. Other characteristics and advantages of the invention will appear on reading the following description, relating to an exemplary embodiment, with reference to the appended figures which represent respectively:

Comme illustré en figure 1 , un exemple de boîtier 10 pour fond de teint, conforme à l'invention, se présente sous la forme globale d'un disque en polypropylène, comportant une partie centrale de fond 11 , entourée d'une bordure 1 composée d'une couronne circulaire 12 limitée par un rebord annulaire 13. Le boîtier 10 est fermé par un opercule 20, représenté en transparence pour laisser apparaître le boîtier.As illustrated in FIG. 1, an example of a case 10 for foundation, in accordance with the invention, is in the overall form of a polypropylene disc, comprising a central bottom part 11, surrounded by a border 1 composed a circular crown 12 limited by a rim annular 13. The housing 10 is closed by a cover 20, shown in transparency to reveal the housing.
L'opercule 20 repose sur la couronne 12 et vient épouser le contour interne du rebord 13 en limite de couronne. L'opercule 20 est muni d'une languette 21, dont la traction permet de décoller l'opercule et donc d'accéder au fond de teint disposé dans un logement limité par le fond 11 et la couronne 12.The cover 20 rests on the crown 12 and matches the internal contour of the rim 13 at the edge of the crown. The cover 20 is provided with a tongue 21, the traction of which makes it possible to take off the cover and therefore to access the foundation disposed in a housing limited by the bottom 11 and the crown 12.
Six orifices transversaux 30 sont régulièrement répartis le long d'un cercle médian de la couronne 12. Ces orifices permettent d'effectuer une aspiration d'air à l'aide d'une pompe adaptée (non représentée) pour maintenir l'opercule dans cette position juste avant d'effectuer la soudure. Des cordons de nervurage circulaire 31 sont également prévus sur la couronne 12 afin de faciliter le thermoscellage de l'opercule sur la couronne.Six transverse orifices 30 are regularly distributed along a median circle of the crown 12. These orifices make it possible to carry out an air suction using a suitable pump (not shown) to maintain the seal in this position just before welding. Circular ribs 31 are also provided on the crown 12 in order to facilitate the heat sealing of the cover on the crown.
L'opercule est formé d'une pellicule de matériau composite aluminium comportant une couche de polypropylène (PP) tournée vers le boîtier et qui fond par chauffage, dans les conditions connues de l'Homme du Métier, pour provoquer la soudure de l'opercule sur la couronne 12.The cover is formed from a film of aluminum composite material comprising a layer of polypropylene (PP) facing the housing and which melts by heating, under conditions known to those skilled in the art, to cause the sealing of the cover. on the crown 12.
Au centre du boîtier 10, une lentille 40 correspond à la zone d'injection de polypropylène réalisé dans un moule adapté aux formes et dimensions du boîtier, dans des conditions de température et de pression connues.At the center of the housing 10, a lens 40 corresponds to the polypropylene injection zone produced in a mold adapted to the shapes and dimensions of the housing, under known temperature and pressure conditions.
Cette lentille 40 est également visible sur la figure 2, qui illustre une vue partielle en coupe transversale du boîtier selon le plan de coupe l-l indiqué en figure 1. Sur la figure 2, apparaissent le fond plat 11 , le logement du fond de teint 14, la couronne 12 et le rebord 13 du boîtier 10. Le fond 11 présente des faces supérieure 11 s et d'appui 11 a planes et parallèles. Le logement 14 est formé par l'espace limité par la surface supérieure 11s du fond 11, le flanc latéral 12f de la couronne 12 et l'opercule 20.This lens 40 is also visible in FIG. 2, which illustrates a partial view in transverse section of the housing according to the cutting plane ll indicated in FIG. 1. In FIG. 2, appear the flat bottom 11, the housing of the foundation 14 , the crown 12 and the rim 13 of the housing 10. The bottom 11 has upper faces 11 s and support 11 a planar and parallel. The housing 14 is formed by the space limited by the upper surface 11s of the base 11, the lateral flank 12f of the crown 12 and the cover 20.
La couronne 12 forme, en liaison avec le rebord 13 et un pied de liaison 15 avec le fond 11 , un pont autour d'un évidement annulaire 16 sur lequel débouchent les orifices transversaux 30. Le rebord 13 présente une surface d'appui 13a de diamètre égale à 25 mm, située dans le même plan que la surface d'appui 11a du fond 11 , et une surface supérieure 13s, surélevée de 0,2 mm par rapport à la surface supérieure 12s de la couronne 12. La hauteur hors tout du rebord 13 est d'environ 1,9 mm, l'épaisseur de la couronne 1 d'environ 1 mm, et celle du fond 11 d'environ 0,6 mm. Comme illustré sur la figure 2, l'orifice 30 présente une forme tronconique selon un angle d'ouverture A d'environ 30 degrés, les nervures 31 une hauteur proche de 0,2 mm, et le flanc latéral 12f est incliné selon un angle B environ égal à 10 degrés, de sorte que le diamètre du logement 14 augmente de la surface supérieure de la couronne 12s en direction de la surface supérieure du fond 11s.The crown 12 forms, in connection with the rim 13 and a connecting leg 15 with the base 11, a bridge around an annular recess 16 on which the transverse orifices open out. The rim 13 has a bearing surface 13a of diameter equal to 25 mm, located in the same plane as the support surface 11a of the base 11, and an upper surface 13s, raised by 0.2 mm relative to the upper surface 12s of the crown 12. The overall height of the rim 13 is approximately 1.9 mm, the thickness of the crown 1 approximately 1 mm, and that of the bottom 11 approximately 0.6 mm. As illustrated in FIG. 2, the orifice 30 has a frustoconical shape at an opening angle A of approximately 30 degrees, the ribs 31 a height close to 0.2 mm, and the lateral flank 12f is inclined at an angle B approximately equal to 10 degrees, so that the diameter of the housing 14 increases from the upper surface of the crown 12s towards the upper surface of the base 11s.
L' évidement réalisé dans la couronne 12 permet d'utiliser un minimum de matériau afin de réduire les coûts au maximum.The recess made in the crown 12 makes it possible to use a minimum of material in order to reduce costs as much as possible.
Dans le but de réduire encore cette épaisseur de matériau sans perdre la résistance recherchée, il est possible d'ajouter, comme illustré en figure 3, de fines nervures radiales 32 régulièrement espacées dans cet évidemment 16.In order to further reduce this thickness of material without losing the desired strength, it is possible to add, as illustrated in FIG. 3, fine radial ribs 32 regularly spaced in this obviously 16.
La forme du boîtier et du décor figurant sur son opercule peuvent être utilisés dans un but décoratif, pour renforcer l'accroche publicitaire.The shape of the case and the decoration appearing on its cover can be used for decorative purposes, to reinforce the advertising catchphrase.
Dans ce but, diverses formes peuvent être créées, en liaison avec le produit contenu, avec éventuellement un opercule de forme différente : par exemple, comme illustré en figure 4a, en forme de fleur 42, avec un opercule 41 et le logement rempli de produit de formes différentes du contour extérieur du boîtier 10. Toute autre forme, technologiquement réalisable peut être envisagée : en goutte d'eau 3 (figure 4b), de forme ovale 4 (figure 4c) ou polygonale 5 (figure 4d).For this purpose, various shapes can be created, in connection with the product contained, possibly with a cover of different shape: for example, as illustrated in FIG. 4a, in the shape of a flower 42, with a cover 41 and the housing filled with product. of different shapes from the outer contour of the housing 10. Any other technologically feasible shape can be envisaged: in a drop of water 3 (FIG. 4b), of oval shape 4 (FIG. 4c) or polygonal 5 (FIG. 4d).
Selon d'autres exemples de réalisation, et comme illustré par les figures 5 et 6, il est possible de prévoir plusieurs logements compartimentés 50 dans les boîtiers 6 et 7, afin de loger plusieurs types de produits différents, ou d'inclure un applicateur dédié au produit : par exemple, une petite éponge 60 pour un fond de teint 61 ou un petit pinceau pour un rouge à lèvres.According to other exemplary embodiments, and as illustrated by FIGS. 5 and 6, it is possible to provide several compartmentalized housings 50 in the housings 6 and 7, in order to accommodate several different types of products, or to include a dedicated applicator to the product: for example, a small sponge 60 for a foundation 61 or a small brush for a lipstick.
Par ailleurs, en référence à la figure 7, le fond 71 du boîtier 8 présente, sur sa surface de contact externe 71a des stries capillaires 70 radiales et courbes, destinées à forcer le produit à se répartir sur toute la surface de la cavité lors du coulage. Le produit coulé à chaud ayant tendance à se figer au contact du plastique, et à ne pas recouvrir toute la surface de la cavité, des "trous" en périphérie ou dans les coins risquent de se former pour des formes non circulaires, et ce défaut de remplissage peut être marqué du fait de la faible épaisseur de produit pâteux. De plus, comme représenté en figure 8, un effet décoratif peut être obtenu à la surface du produit du fait de la faible épaisseur du produit pâteux. Des gravures 80, réalisées sur le fond 81 du boîtier 9, sont transmises en surface du produit où apparaissent les éléments décoratifs 82 avec un relief correspondant.Furthermore, with reference to FIG. 7, the bottom 71 of the housing 8 has, on its external contact surface 71a, capillary ridges 70 which are radial and curved, intended to force the product to be distributed over the entire surface of the cavity during casting. The hot poured product tends to freeze in contact with the plastic, and not to cover the entire surface of the cavity, "holes" in the periphery or in the corners may form for non-circular shapes, and this defect filling can be marked due to the thin thickness of pasty product. In addition, as shown in Figure 8, a decorative effect can be obtained on the surface of the product due to the thinness of the pasty product. Engravings 80, produced on the bottom 81 of the housing 9, are transmitted to the surface of the product where the decorative elements 82 appear with a corresponding relief.
La hauteur de la gravure provoque en effet une variation d'épaisseur de produit relativement importante et le léger retrait de la pâte lors de son refroidissement reproduit alors le motif sur sa surface, de façon atténuée. Il s'ensuit un effet d'ombré plus ou moins visible selon les pigments de coloration utilisés dans la pâte.The height of the engraving in fact causes a relatively large variation in product thickness and the slight shrinkage of the paste during its cooling then reproduces the pattern on its surface, attenuated. There follows a more or less visible shade effect depending on the coloring pigments used in the paste.
De plus, des pigments ayant une forme aplatie, tels que les paillettes ou les nacres, ont tendance à s'orienter dans les zones de variation d'épaisseur, augmentant ainsi l'effet optique du produit. Ces éléments, éventuellement informatifs, tel qu'un logo ou un texte, apparaissent soit par transparence, si le produit pâteux n'est pas totalement opaque, soit par "ombrage" de la surface si le produit est totalement opaque.In addition, pigments having a flattened shape, such as flakes or mother-of-pearl, tend to orient themselves in the zones of variation of thickness, thus increasing the optical effect of the product. These elements, possibly informative, such as a logo or a text, appear either by transparency, if the pasty product is not completely opaque, or by "shading" of the surface if the product is completely opaque.
L'invention n'est pas limitée aux exemples de réalisation décrit et représenté.The invention is not limited to the embodiments described and shown.
Le boîtier ultra-plat conforme à l'invention peut être présenté collé par son fond sur une page de revue ou d'un magazine, éventuellement intégré à une création graphique publicitaire.
