Description
CONDITIONNEMENT EN RéCIPIENTS REGROUPES SOUS UN COUVERCLE
SECABLE EN UNITES DE CONSOMMATION
DOMAINE DE L'INVENTION
L'invention concerne le domaine du conditionnement de produits destinés au grand public, notamment les moyens, autres que les suremballages, permettant de présenter et de commercialiser, regroupés, plusieurs récipients unitaires.PACKAGING IN CONTAINERS CONTAINED UNDER A LID
SHORTABLE IN CONSUMPTION UNITS
FIELD OF THE INVENTION
The invention relates to the field of packaging products intended for the general public, in particular the means, other than overpacks, making it possible to present and market, grouped together, several unit containers.
ETAT DE LA TECHNIQUE
On connaît déjà de nombreux produits alimentaires qui sont commercialisés regroupés.STATE OF THE ART
Many food products are already known which are sold together.
Par exemple, la plupart des produits laitiers frais, typiquement les yaourts, sont présentés par plaques de 4 à 8 pots de yaourt individuels. Dans le cas particulier des pots de yaourt, la fabrication est du type FFS (Form/FiWSeal) et comprend, en ligne, la mise en forme d'une bande de polystyrène (PS) pour former les pots solidarisés et donc regroupés par 4 à 8 ou plus, le remplissage de ces pots, et la fermeture de ces pots par thermoscellage d'une bande d'operculage (par exemple une bande de PET métallisé imprimée sur une fice, et ayant une couche de vernis thermoscellant sur l'autre face). Ce regroupement de pots est généralement suremballé dans un carton imprimé, à la fois pour assurer la protection de l'opercule, pour réaliser un empilement de plaques de pots, et aussi pour ofEir un aspect extérieur plus attractif.For example, most fresh dairy products, typically yogurt, are presented in plates of 4 to 8 jars of individual yogurt. In the particular case of yogurt pots, the manufacturing is of the FFS (Form / FiWSeal) type and includes, in line, the shaping of a strip of polystyrene (PS) to form the pots joined together and therefore grouped by 4 to 8 or more, filling these pots, and closing these pots by heat sealing a sealing strip (for example a strip of metallized PET printed on a fice, and having a layer of heat-sealing varnish on the other face ). This grouping of pots is generally overwrapped in a printed carton, both to ensure the protection of the lid, to make a stack of pot plates, and also to offer a more attractive external appearance.
PROBLEMES POSES
Un des problèmes que pose l'état de la technique est celui de la présence d'un suremballage, que le consommateur final doit enlever, et dont il doit se débarrasser, sous peine d'encombrer son réfrigérateur de cartons inutiles. Compte tenu de la place prise notament par les porduits frais, il est donc important pour le consommateur de libérer de la place dans son réfrigérateur. PROBLEMS POSED
One of the problems posed by the state of the art is that of the presence of an overpack, which the end consumer must remove, and which he must get rid of, on pain of cluttering his refrigerator with unnecessary boxes. Taking into account the space taken in particular by fresh porduits, it is therefore important for the consumer to free up space in his refrigerator.
Un autre problème est d'offrir, en particulier pour des produits autres que des yaourts, un conditionnement regroupé qui ne rappelle pas celui des yaourts, sous peine d'avoir pour ce produit une image totalement brouillée pour le consommateur. Another problem is to offer, in particular for products other than yogurts, a grouped packaging which does not recall that of yogurts, under penalty of having for this product a completely blurred image for the consumer.
Un autre problème est d'offrir un concept de conditionnement qui soit flexible et adaptable aux conditions pratiques de stockage et de commercialisation, en particulier dans la chaîne du froid.Another problem is to offer a packaging concept that is flexible and adaptable to practical storage and marketing conditions, particularly in the cold chain.
Un autre problème est de gagner de la place dans la logistique amont des produits emballés.Another problem is to gain space in the upstream logistics of packaged products.
DESCRIPTION DE L'INVENTION
Selon l'invention, le conditionnement de produits alimentaires en récipients regroupés et formés de corps de récipients dotés de moyens de fermeture pelables, est caractérisé en ce que, a) lesdits corps de récipients sont regroupés sous un couvercle unique, b) chaque dit corps de récipient est individuellement rendu solidaire dudit couvercle unique, c) ledit couvercle unique est sécable en portions de couvercle unique, à chaque dite portion étant solidarisé un corps de récipient, grâce à un moyen de partition, selon des lignes prédétermmées qui déterminent sur ledit couvercle unique autant de portions de couvercle que de corps de récipients à regrouper.DESCRIPTION OF THE INVENTION
According to the invention, the packaging of food products in grouped containers formed by container bodies provided with peelable closure means, is characterized in that, a) said container bodies are grouped under a single cover, b) each said body of container is individually made integral with said single cover, c) said single cover is breakable into portions of single cover, to each said portion being secured a container body, by means of partition, according to predetermined lines which determine on said cover as many cover portions as there are container bodies to group together.
d) le matériau dudit couvercle unique est choisi en fonction des conditions de stockage et de transfert desdits produits alimentaires conditionnés en corps de récipients regroupés, de manière à assurer la tenue au choc dudit conditionnement et la sécabilité dudit couvercle unique.d) the material of said single cover is chosen according to the conditions of storage and transfer of said food products packaged in the body of grouped containers, so as to ensure the impact strength of said packaging and the breakability of said single cover.
Cette combinaison de caractéristiques permet de résoudre les problèmes selon l'invention. En effet, d'une part, le conditionnement selon l'invention diminue sensiblement le volume occupé, tant en amont dans le circuit de distribution car il permet un gerbage direct et stable, qu'en aval dans le réfrigérateur du consommateur final. I1 supprime le suremballage en carton et constitue un mode pratique de regroupement et de fractionnement de produits emballés unitairement, correspondant aux nouveaux modes de vie des consommateurs, et offrant à ces consommateurs un renouvellement de l'image des produits commercialisés jusqu'ici sous suremballage en carton.This combination of characteristics makes it possible to solve the problems according to the invention. On the one hand, the packaging according to the invention significantly reduces the volume occupied, both upstream in the distribution circuit because it allows direct and stable stacking, and downstream in the refrigerator of the final consumer. It removes the cardboard overpack and constitutes a practical method of grouping and splitting individually packaged products, corresponding to the new lifestyles of consumers, and offering these consumers a renewal of the image of the products marketed so far in overpack in cardboard.
DESCRIPTION DES FIGURES
Les figures la et lb correspondent respectivement à une vue de dessus et à une vue en coupe d'un conditionnement (1) selon une première modalité de l'invention. Ce conditionnement (1) comprend un couvercle unique (3) dotée de lignes de partition (6) dont la rupture définit 6 portions (5) de couvercle unique (3). A chaque portion (5) un corps de récipient (2) se trouve fixé par thermoscellage et formation d'une soudure circulaire (72) entre le bord (20) de chaque récipient (2) et ledit couvercle unique (3) qui constitue à la fois une fermeture étanche du corps de récipient (2) et un moyen de sa fixation audit couvercle unique (3). Le couvercle unique (3) est doté de creux circulaires (30) adaptés au positionnement des fonds (21) des corps de récipients (2), comme représenté à la figure lb.DESCRIPTION OF THE FIGURES
Figures la and lb respectively correspond to a top view and a sectional view of a package (1) according to a first embodiment of the invention. This packaging (1) comprises a single cover (3) provided with partition lines (6), the rupture of which defines 6 portions (5) of single cover (3). To each portion (5) a container body (2) is fixed by heat sealing and formation of a circular weld (72) between the edge (20) of each container (2) and said single cover (3) which constitutes at both a sealed closure of the container body (2) and a means of fixing it to said single cover (3). The single cover (3) is provided with circular recesses (30) adapted to the positioning of the bottoms (21) of the container bodies (2), as shown in FIG. 1b.
La figure lc est une vue en coupe partielle d'un bord (20) d'un corps de récipient (2) réalisé en matériau multicouches et constitué d'une couche intérieure (201) et d'une couche extérieure (202), le bord (20) comprenant un jonc périphérique en relief(203).Figure lc is a partial sectional view of an edge (20) of a container body (2) made of multilayer material and consisting of an inner layer (201) and an outer layer (202), the edge (20) comprising a raised peripheral ring (203).
Les figures 2a et 2b sont analogues aux figures la et lb, mais illustrent une autre modalité de l'invention. Dans ce cas, le couvercle unique (3) regroupe des corps de récipients (2) munis de leur propre moyen de fermeture étanche, par exemple un opercule (4). Leur fixation audit couvercle unique (3) est assurée par des rainures latérales (70), les bords (20,40) des corps de récipients (2) et des opercules (4) étant glissés dans ces rainures (70) depuis un côté (32) où ces rainures sont débouchantes.Figures 2a and 2b are similar to Figures la and lb, but illustrate another mode of the invention. In this case, the single cover (3) groups together container bodies (2) provided with their own sealed closure means, for example a cover (4). Their attachment to said single cover (3) is ensured by lateral grooves (70), the edges (20,40) of the container bodies (2) and of the lids (4) being slid into these grooves (70) from one side ( 32) where these grooves are through.
Après chargement dudit couvercle unique, il suffit de pincer avec une pince chauffante ou des mors chauffants les extrémités de rainures du côté (32), pour obturer ladite rainure, comme représenté à la figure 2c, et empêcher ainsi toute désolidarisation desdits corps de récipients et dudit couvercle unique (3).After loading of said single cover, it suffices to pinch the ends of grooves on the side (32) with a heating tongs or heating jaws, to close said groove, as shown in FIG. 2c, and thus prevent any separation of said container bodies and of said single cover (3).
Les figures 3a et 3b sont analogues aux figures 2a et 2b, mais illustrent une autre modalité de l'invention dans laquelle la fixation des corps de récipients (2) munis de leurs opercules de fermeture (4) audit couvercle unique (3) est réalisée au moyen de crans d'encliquetage (71), chaque portion (5) de couvercle unique (3) portant 4 desdits crans (71).Figures 3a and 3b are similar to Figures 2a and 2b, but illustrate another embodiment of the invention in which the fixing of the container bodies (2) provided with their closing lids (4) to said single cover (3) is carried out by means of latching notches (71), each portion (5) of single cover (3) carrying 4 of said notches (71).
Les figures 4a et 4b illustrent le cas où ledit couvercle unique (3) comprend, sur sa face interne, et à l'emplacement où le bord (20) du récipent (2) est solidarisé audit couvercle unique, un cordon circulaire de hot-melt destiné à solidariser de manière étanche le matériau constituant ledit couvercle unique (3) au matériau constituant ledit récipient (2).Figures 4a and 4b illustrate the case where said single cover (3) comprises, on its internal face, and at the location where the edge (20) of the container (2) is secured to said single cover, a circular cord of hot- melt intended to seal the material constituting said single cover (3) to the material constituting said container (2).
La figure 4a est une vue de dessous dudit couvercle unique (3) où sont représentés autant de cordons circulaires de hot-melt (720) que de récipients à regrouper sous ledit couvercle unique (3). FIG. 4a is a bottom view of said single cover (3) where as many circular hot-melt beads (720) are represented as there are containers to be grouped under said single cover (3).
La figure 4b représente, en coupe verticale, I'opération de thermoscellage aux ultra-sons, une sonde à ultra-sons (9) étant appliquée sur une plaque métallique (10), appuyant ellemême sur ledit couvercle unique (3), de manière à écraser le cordon de hot-melt (720) et à assurer l'adhésion et l'étanchéité dudit couvercle unique (3) et desdits récipients (2).FIG. 4b represents, in vertical section, the ultrasonic heat-sealing operation, an ultrasonic probe (9) being applied to a metal plate (10), pressing itself on said single cover (3), so to crush the hot melt bead (720) and to ensure the adhesion and sealing of said single cover (3) and said containers (2).
DESCRIPTION DETAILLE DE L'INVENTION
Selon une première modalité du conditionnement (1) de l'invention, ledit couvercle unique constitue ledit moyen de fermeture, le rebord (20) de chaque corps de récipient (2) étant fixé de manière étanche sous ledit couvercle unique (3) grâce à un moyen d'étanchéité, ledit moyen d'étanchéité étant choisi pour assurer la séparation facile par pelage de ladite portion (5) de couvercle unitaire (3) et dudit corps de récipient (2) correspondant.DETAILED DESCRIPTION OF THE INVENTION
According to a first method of packaging (1) of the invention, said single cover constitutes said closing means, the rim (20) of each container body (2) being fixed in leaktight manner under said single cover (3) thanks to a sealing means, said sealing means being chosen to ensure easy separation by peeling of said portion (5) of unitary cover (3) and of said corresponding container body (2).
Cette modalité est représentée aux figures la à lc.This modality is shown in Figures la to lc.
Selon une première variante, ledit moyen d'étanchéité est un couche de scellage (72) formée par le thermoscellage par ultra-sons du rebord (20) de chaque corps de récipient (2) et dudit couvercle unique (3), la durée et la pression de thermoscellage étant choisies de manière à assurer ladite séparation facile par pelage. ll est ainsi éventuellement possible de souder directement par thermoscellage le matériau dudit couvercle unique (3) au matériau dudit corps de récipient (2). According to a first variant, said sealing means is a sealing layer (72) formed by ultrasonic heat sealing of the rim (20) of each container body (2) and of said single cover (3), the duration and the heat sealing pressure being chosen so as to ensure said easy separation by peeling. It is thus possibly possible to directly weld by heat sealing the material of said single cover (3) to the material of said container body (2).
Selon une autre variante, ledit thermoscellage est assuré par un cordon d'adhésif du type hot-melt) > , adhérent initialement au matériau dudit couvercle unique (3), ou au matériau dudit corps de récipient (2).According to another variant, said heat sealing is provided by a bead of adhesive of the hot-melt type)>, initially adhering to the material of said single cover (3), or to the material of said container body (2).
Les figures 4a et 4b illustrent le cas ou les cordons de hot-melt (720) sont portés initialement par ledit couvercle unique (3).Figures 4a and 4b illustrate the case where the hot melt cords (720) are initially carried by said single cover (3).
La couche de scellage (72,720) est choisi notamment en fonction de la nature des matériaux à solidariser, celui du couvercle unique (3) et celui du récipient (2) pouvant être les mêmes ou être différents.The sealing layer (72,720) is chosen in particular as a function of the nature of the materials to be joined, that of the single cover (3) and that of the container (2) possibly being the same or being different.
Selon une autre modalité de conditionnement (1) selon l'invention, chaque corps de récipient (2) est muni d'un moyen de fermeture (4), ledit couvercle unique (3) assurant le regroupement de récipients fermés grâce à la coopération des bords (20,40) desdits récipients fermés avec des moyens d'accrochage (70,71) dudit couvercle unique (3).According to another packaging method (1) according to the invention, each container body (2) is provided with a closure means (4), said single cover (3) ensuring the regrouping of closed containers thanks to the cooperation of edges (20,40) of said closed containers with hooking means (70,71) of said single cover (3).
Cette modalité est illustrée aux figures 2a à 2c et 3a et 3b.This method is illustrated in Figures 2a to 2c and 3a and 3b.
Le moyen de fermeture est typiquement un opercule, connu en lui-même, et qui peut être notamment en matériau multicouches, une des couches pouvant être une couche en matériau barrière connu en lui-même.The closure means is typically a cover, known in itself, and which can be in particular of multilayer material, one of the layers possibly being a layer of barrier material known in itself.
Selon une première variante, lesdits moyens d'accrochage (70,71) sont constitués par un moyen choisi parmi : ramures (70) qui permettent un encliquetage latéral, crans ou crochets (71) qui permettent un encliquetage axial.According to a first variant, said attachment means (70, 71) are constituted by means chosen from: antlers (70) which allow lateral snap-fastening, notches or hooks (71) which allow axial snap-fastening.
Les figures 2a à 2c correspond au cas où des rainures latérales (70) constituent ledit moyen d'accrochage, alors que les figures 3a et 3b correspond au cas où des crans ou crochets (71) constituent ledit moyen d'accrochage.FIGS. 2a to 2c correspond to the case where lateral grooves (70) constitute said attachment means, while FIGS. 3a and 3b correspond to the case where notches or hooks (71) constitute said attachment means.
En outre, il est possible selon l'invention que ledit couvercle unique (3) comprenne des moyens, éventuellement connus en eux- même s, pour assurer l'inviolabilité dudit conditionnement.In addition, it is possible according to the invention that said single cover (3) comprises means, possibly known in themselves, to ensure the inviolability of said packaging.
Ainsi dans la modalité illustrée aux figures la et Ib, I'inviolabilité est assurée automatiquement, par le fait qu'un corps de récipient (2), frauduleusement détaché dudit couvercle unique (3), ne pourrait pas être remis en place, sans moyens particuliers (adhésifs, moyens de thermoscellage...) qui ne sont pas facilement accessibles. Thus, in the mode illustrated in FIGS. 1 a and 1 b, inviolability is ensured automatically, by the fact that a container body (2), fraudulently detached from said single cover (3), could not be replaced without means individuals (adhesives, heat sealing means, etc.) that are not easily accessible.
De même, dans la modalité illustrée aux figures 2a à 2c, I'inviolabilité est assurée par le thermoscellage (pincement à chaud) des extrémités des rainures (70) sur un côté (32) du couvercle unique (3). Voir figure 2c.Likewise, in the mode illustrated in FIGS. 2a to 2c, inviolability is ensured by heat sealing (hot pinching) of the ends of the grooves (70) on one side (32) of the single cover (3). See figure 2c.
Dans ce cas, les corps de récipients (2) ne peuvent pas être séparés dudit couvercle unique (3) sans former des portions (5), ce qui rend donc évidente toute tentative d'effraction.In this case, the container bodies (2) cannot be separated from said single cover (3) without forming portions (5), which therefore makes any attempt to break in.
Dans le cas de la modalité illustrée aux figures 3a et 3b, les crans (71) sont choisis quant'à leur forme et leur matière de façon à ce que, d'une part, l'encliquetage dudit couvercle unique (3) et desdits corps de récipients (2) fermés ait lieu par application dudit couvercle unique (3) porté à une température suffisante pour que les crans (71) aient une souplesse suffisante pour permettre ledit encliquetage par appui vertical, mais que, par contre d'autre part, on ne puisse, à froid, séparer un corps de récipient (2) fermé sans rompre par pliage un cran (71).In the case of the mode illustrated in FIGS. 3a and 3b, the notches (71) are chosen as regards their shape and their material so that, on the one hand, the snap-fastening of said single cover (3) and of said body of closed containers (2) takes place by application of said single cover (3) brought to a sufficient temperature so that the notches (71) have sufficient flexibility to allow said latching by vertical support, but that, on the other hand on the other hand , one can not, cold, separate a container body (2) closed without breaking by bending a notch (71).
ll est avantageux selon l'invention d'avoir un conditionnement (1) dans lequel chaque dite portion (5) de couvercle unique (3) présente un profil (creux (30) ou relief 31)) adapté au fond (21) dudit corps de récipient (2) de manière à assurer un gerbage stable desdits conditionnements (1). It is advantageous according to the invention to have a packaging (1) in which each said portion (5) of single cover (3) has a profile (hollow (30) or relief 31)) adapted to the bottom (21) of said body container (2) so as to ensure a stable stacking of said packages (1).
Les figures lb et 2b illustrent le cas où le couvercle commun (3) présente des creux (30), alors que la figure 3b illustre le cas où le couvercle commun (3) présente des reliefs arrondis (31).Figures 1b and 2b illustrate the case where the common cover (3) has recesses (30), while Figure 3b illustrates the case where the common cover (3) has rounded reliefs (31).
En ce qui concerne le matériau dudit conditionnement (1) selon l'invention, et dans le cas où la fixation des corps de récipient (2) audit couvercle unique (3) se fait par thermoscellage, le matériau dudit couvercle unique (3) peut être du PP, le matériau dudit corps de récipient (2) peut être en un matériau bicouche, la couche externe étant en PP, et la couche interne en alliage PP-PE contenant de 30 à 70% de PE et comportant au niveau du rebord un relief ou jonc périphérique de forme convexe, comme illustré à la figure lc. As regards the material of said packaging (1) according to the invention, and in the case where the fixing of the container bodies (2) to said single cover (3) is effected by heat sealing, the material of said single cover (3) can be PP, the material of said container body (2) may be of a two-layer material, the outer layer being of PP, and the inner layer of PP-PE alloy containing 30 to 70% of PE and comprising at the rim a relief or peripheral ring of convex shape, as illustrated in Figure lc.
On peut aussi avoir le cas inverse dans lequel le matériau dudit corps de récipient (2) est en PP, le matériau dudit couvercle unique (3) est en un matériau bicouche, la couche externe (202) étant en PP, et la couche interne (201) en alliage PP-PE contenant de 30 à 70% de PE et comportant un jonc périphérique (203) de forme convexe en regard dudit rebord. Voir figure lc.We can also have the opposite case in which the material of said container body (2) is made of PP, the material of said single cover (3) is made of a two-layer material, the outer layer (202) being made of PP, and the inner layer (201) made of PP-PE alloy containing 30 to 70% of PE and comprising a peripheral ring (203) of convex shape facing said flange. See figure lc.
L'utilisation et l'intérêt d'un matériau bicouches PP-PE figurent déjà dans la demande française n" 93 15033 au nom de la demanderesse.The use and usefulness of a PP-PE bilayer material is already listed in French application No. 93 15033 in the name of the applicant.
ll peut être avantageux, selon la nature des produits alimentaires (9) à conditionner, d'avoir comme matériau dudit couvercle unique (3), un matériau multicouches comprenant une couche de matériau barrière connu en elle-même (PVDC, EVOH, etc...). It may be advantageous, depending on the nature of the food products (9) to be packaged, to have as material of said single cover (3), a multilayer material comprising a layer of barrier material known per se (PVDC, EVOH, etc. ..).
Selon, notamment,la nature des produits à conditionner et les conditions de stockage (température de stockage ), on peut choisir selon l'invention, à titre d'exemples nonlimitatifs, d'autres matériaux pour former ledit couvercle unique (3): PA, PET, PS ou
ABS.According to, in particular, the nature of the products to be packaged and the storage conditions (storage temperature), other materials can be chosen according to the invention, by way of nonlimiting examples, to form said single cover (3): PA , PET, PS or
ABS.
Dans le cas illustré aux figures 2a à 2c et 3a et 3b où lesdits corps de récipients (2) fermés sont solidarisés audit couvercle unique par des moyens de fixation, typiquement des moyens mécaniques, le matériau constituant ledit couvercle unique (3) est choisi parmi: le PP homopolymère, le PP copolymère statistique, le PP copolymère block, ou leurs mélanges ou alliages, de manière à assurer la tenue au choc et la sécabilité dudit couvercle unique (3).In the case illustrated in FIGS. 2a to 2c and 3a and 3b where said closed container bodies (2) are secured to said single cover by fixing means, typically mechanical means, the material constituting said single cover (3) is chosen from : homopolymer PP, random copolymer PP, block copolymer PP, or mixtures or alloys thereof, so as to ensure the impact strength and the breakability of said single cover (3).
n peut être avantageux d'avoir un conditionnement (1) dans lequel le matériau constituant ledit couvercle unique (3) et celui constituant ledit corps de récipient (2) sont les mêmes, ou, s'ils sont différents, recyclables ensemble. It may be advantageous to have a packaging (1) in which the material constituting said single cover (3) and that constituting said container body (2) are the same, or, if they are different, recyclable together.
Selon l'invention, ledit moyen de partition est choisi parmi: ligne d'affàiblissement (6) par réduction d'épaisseur localisée ou liaison entre lesdites portions de couvercle par des ponts, absence localisée d'un rebord audit couvercle unique, ou tout autre moyen connu en soi permettant une partition dudit couvercle unique par pliage permettant de former lesdites portions (5).According to the invention, said partition means is chosen from: line of weakening (6) by localized reduction in thickness or connection between said cover portions by bridges, localized absence of a rim at said single cover, or any other means known per se allowing a partition of said single cover by folding making it possible to form said portions (5).
Le conditionnement selon l'invention s'applique à de nombreux produits, et en ce qui concerne les produits alimentaires (9), plus spécialement, mais non exclusivement, les produits suivants : les glaces, les sorbets, les crèmes chocolatées, les gâteaux glacés, les sauces, les pâtes fromagères, des produits demi-secs ou secs, les biscuits salés ou non pour apéritif.The packaging according to the invention applies to many products, and with regard to food products (9), more especially, but not exclusively, the following products: ice creams, sorbets, chocolate creams, frozen cakes , sauces, cheese pasta, semi-dry or dry products, salted or unsalted biscuits for aperitifs.
EXEMPLES DE REALISATION
On a fabriqué par thermoformage de PP homopolymère en bande de 0,4 mm des couvercles (3) correspondant aux figures la et lb. On a préparé des corps de récipients en matériau bicouches de 0,25 mm d'épaisseur, avec une couche interne de 0,1 mm en alliage PE-PP à 50% de PP, et une couche externe en PP de 0,15 mm d'épaisseur.EXAMPLES OF REALIZATION
Lids (3) corresponding to FIGS. 1a and 1b were produced by thermoforming of PP homopolymer into a 0.4 mm strip. Bodies of containers made of 0.25 mm thick bilayer material were prepared, with an internal layer of 0.1 mm made of PE-PP alloy at 50% PP, and an external layer of PP of 0.15 mm thick.
On a fabriqué par injection de PP copolymère block des couvercles (3) de 0,5 mm d'épaisseur, selon les figures 2a et 2b, adaptés à des corps de récipient en PP de 0,3 mm d'épaisseur, fermés par un opercule d'aluminium.Lids (3) 0.5 mm thick, according to FIGS. 2a and 2b, were produced by injection of block copolymer PP, adapted to 0.3 mm thick PP container bodies, closed by a aluminum seal.
On a aussi fabriqué par injection de PP homopolymère des couvercles (3) 0,5 mm d' épaisseur, selon les figures 3a et 3b, avec des crochets (71) de 1,5 mm de hauteur, adaptés comme précédemment à des corps de récipients en PP fermés par un opercule d'aiuininiuni. Lids (3) 0.5 mm thick, according to FIGS. 3a and 3b, were also manufactured by injection of PP homopolymer, with hooks (71) 1.5 mm high, adapted as before to PP containers closed with an auininiuni seal.
Dans tous les cas, on a formé des lignes d'affaiblissement (6) par l'outil de conformation, ces lignes ayant une épaisseur typiquement égale au tiers de l'épaisseur du couvercle (3), la formation de portions étant aussi favorisée par la présence d'amorces de déchirure (33). In all cases, weakening lines (6) have been formed by the shaping tool, these lines having a thickness typically equal to one third of the thickness of the cover (3), the formation of portions being also favored by the presence of tear primers (33).
Les essais stockage, de transport des conditionnements (1) gerbés ont montré tout l'intérêt de l'invention.The storage and transport tests of the stacked packaging (1) showed the whole advantage of the invention.
AVANTAGES DE L'INVENTION
