Description

Suremballage de produits. Overwrapping of products.
La présente invention est relative à un emballage de produits du type comprenant une série d'emballages primaires pour les produits, rassemblés dans un suremballage. Elle s'applique en particulier au conditionnement de produits alimentaires plats tels que des tablettes de gomme à mâcher, des plaquettes de fromage, des biscuits ou des barres de chocolat, ou encore de cartes à puce, mais elle peut également s'appliquer au conditionnement de doses de produits liquides, de serviettes préhumidifiées et, plus géné¬ ralement, de divers produits destinés à être utilisés individuellement ou par doses séparées.The present invention relates to a packaging of products of the type comprising a series of primary packaging for the products, gathered in an overpack. It applies in particular to the packaging of flat food products such as chewing gum tablets, cheese wafers, cookies or chocolate bars, or even chip cards, but it can also be applied to packaging doses of liquid products, pre-moistened towels and, more generally, various products intended to be used individually or in separate doses.
Dans le cas des produits alimentaires plats précités, le suremballage est souvent constitué par une enveloppe réalisée à partir d'une feuille roulée ou pliée, par exemple en papier ou en un complexe réalisé, par exemple, à partir de l'association d'un film plasti¬ que, de papier et d'aluminium (ou de la combinaison de deux d'entre eux); cette feuille entoure et enveloppe alors un empilement desdits produits pour former un parallélépipède maintenu par collage d'un bord longitudi¬ nal de la feuille sur le bord longitudinal opposé; les extrémités du parallélépipède sont maintenues en position repliées, par exemple par thermoscellage, pour former l'une le fond, l'autre le couvercle de l'enveloppe.In the case of the aforementioned flat food products, the overpack is often formed by an envelope made from a rolled or folded sheet, for example made of paper or a complex made, for example, from the combination of a plastic film, paper and aluminum (or a combination of two of them); this sheet then surrounds and envelops a stack of said products to form a parallelepiped held by gluing a longitudi¬ nal edge of the sheet on the opposite longitudinal edge; the ends of the parallelepiped are kept in the folded position, for example by heat sealing, to form one the bottom, the other the cover of the envelope.
Pour ouvrir un tel emballage, on procède par exemple par décollement et dépliage du couvercle de l'enveloppe; lorsqu'une bande de déchirure est prévue à cet effet à proximité du couvercle de l'enveloppe, on procède de préférence par déchirement de cette bande et enlèvement total et définitif du couvercle.To open such packaging, one proceeds for example by detachment and unfolding of the cover of the envelope; when a tear strip is provided for this purpose near the cover of the envelope, the procedure is preferably by tearing this strip and removing the cover completely and definitively.
Un tel emballage est très économique pour des produits de consommation courante et très avantageux puisqu'il permet de les conserver groupés dans l'enve¬ loppe et disponibles à tout instant pour la distribution et la consommation.Such packaging is very economical for everyday consumer products and very advantageous since it makes it possible to keep them grouped in the envelope and available at all times for distribution and consumption.
Cependant, dès que l'enveloppe d'un emballage de ce type a été ouverte, elle n'est plus refermable avec sécurité et/ou elle est définitivement dépourvue d'un couvercle; elle risque donc à tout moment de laisser échapper les produits restants qu'elle contient, ce qui représente un grave inconvénient. Ceci est particulière- ment gênant lorsque l'emballage dont l'enveloppe est déjà ouverte est laissée dans la poche d'un vêtement, dans un sac ou une valise, ou encore dans la boîte à gants d'un véhicule. Les produits restants qu'elle contient peuvent alors s'y retrouver dispersés avec d'autres objets. Ces emballages connus présentent également d'autres inconvénients :However, as soon as the envelope of a package of this type has been opened, it can no longer be closed securely and / or it is definitively devoid of a cover; it therefore risks at any time to escape the remaining products which it contains, which represents a serious drawback. This is particularly troublesome when the package, the envelope of which is already open, is left in the pocket of a garment, in a bag or suitcase, or even in the glove compartment of a vehicle. The remaining products it contains can then be dispersed there with other objects. These known packages also have other drawbacks:
- dès qu'un produit a été consommé, le suremballage s'affaisse sur lui-même et perd son attrait esthétique; - les déchets à jeter à chaque consommation d'un produit, constitués par un emballage primaire complet, sont importants; il est nécessaire de rendre visuellement attrayante la totalité de la surface des emballages primaires;- as soon as a product has been consumed, the overpack collapses on itself and loses its aesthetic appeal; - the waste to be discarded with each consumption of a product, consisting of a complete primary packaging, is significant; it is necessary to make the entire surface of the primary packaging visually attractive;
- le consommateur doit saisir chaque produit directement avec les doigts pour le porter à la bouche, après avoir ouvert l'emballage primaire.- the consumer must grasp each product directly with the fingers to bring it to the mouth, after opening the primary packaging.
L'invention a pour but d'éliminer tous ces inconvénients.The object of the invention is to eliminate all these drawbacks.
A cet effet, elle a pour objet un emballage de produits du type précité, caractérisé en ce que chaque emballage primaire comporte une région solidaire du suremballage, et, en dehors de cette région, une zone de pré-rupture qui délimite une partie jetable de l'embal- lage primaire.To this end, it relates to a packaging of products of the aforementioned type, characterized in that each primary packaging comprises a region integral with the overpack, and, outside this region, a pre-rupture zone which delimits a disposable part of the packaging primary age.
L'emballage suivant l'invention peut compor¬ ter une ou plusieurs des caractéristiques suivantes:The packaging according to the invention can have one or more of the following characteristics:
- chaque produit individuel est préemballé dans un emballage primaire, tous les emballages primaires sont empilés et fixés au suremballage par une première extrémité, et l'autre extrémité du suremballage, voisine des zones de pré-rupture, est ouvrable, de sorte qu'après ouverture du suremballage, chaque produit individuel peut être saisi en même temps que la seconde extrémité de leur emballage primaire;- each individual product is prepackaged in a primary packaging, all the primary packaging are stacked and fixed to the overpack by a first end, and the other end of the overpack, close to the pre-break zones, is openable, so that after opening of the overpack, each individual product can be seized at the same time as the second end of their primary packaging;
- la fixation des emballages primaires est réalisée par collage des emballages primaires extrêmes au suremballage par une tranche d'extrémité et par une partie de leur surface latérale, notamment adjacente à cette tranche d'extrémité, et par collage des autres emballages primaires au suremballage seulement par une tranche d'extrémité.- The primary packaging is fixed by gluing the extreme primary packaging to the overpack by an end edge and by a part of their lateral surface, in particular adjacent to this end edge, and by bonding the other primary packages to the overpack only by an end edge.
- le collage est réalisé au moyen d'une colle du type thermoréactivable;- The bonding is carried out using an adhesive of the heat-activated type;
- le collage est réalisé au moyen d'une colle du type colle à froid activable par pression;- The bonding is carried out using an adhesive of the cold glue type activatable by pressure;
- ladite autre extrémité du suremballage est séparable du reste du suremballage, notamment au moyen d'une bande de déchirure;- Said other end of the overpack is separable from the rest of the overpack, in particular by means of a tear strip;
- la distance séparant la ligne de pré¬ rupture de l'extrémité. libre de la partie jetable de l'emballage primaire est inférieure à la largeur des pro¬ duits; - les produits individuels sont des tablettes de gomme à mâcher;- the distance separating the pre-rupture line from the end. free of the disposable part of the primary packaging is less than the width of the products; - the individual products are chewing gum tablets;
- le suremballage est une boîte rigide à couvercle ouvrable comprenant un fond alvéolé, les emballages primaires étant des tubes rigides scellés dont une extrémité est fixée dans chaque alvéole respective- ment.- the overwrap is a rigid box with an opening lid comprising a honeycomb bottom, the primary packaging being rigid sealed tubes, one end of which is fixed in each respective honeycomb - is lying.
Des exemples de réalisation de l'invention vont maintenant être décrits en regard des dessins annexés, sur lesquels : - la Figure 1 est une vue en perspective d'un emballage selon l'invention dont l'enveloppe est fermée;Examples of embodiments of the invention will now be described with reference to the accompanying drawings, in which: - Figure 1 is a perspective view of a package according to the invention, the envelope of which is closed;

- la Figure 13 représente schématiquement, en coupe verticale, un autre mode de réalisation de l'embal¬ lage suivant l'invention.- Figure 13 shows schematically, in vertical section, another embodiment of the packaging according to the invention.
L'emballage représenté aux Figures 1 à 5 comprend un suremballage 1 constitué par une enveloppe souple qui contient des produits plats allongés 2 préemballés et empilés. Les produits 2 peuvent être par exemple des produits alimentaires préemballés, tels que des tablettes de gomme à mâcher, des plaquettes de fromage, des biscuits ou des barres de chocolat, ou encore d'autres produits pré-emballés tels que des cartes à puce. L'enveloppe souple 1 comprend un corps 3 de forme générale parallélépipédique fermé à ses deux extrémités, l'une constituant le fond 4, l'autre cons¬ tituant le couvercle 5, par pliage et collage des extrémités du corps 3 sur elles-mêmes. Le corps 3 comporte également une bande de déchirure 6 sur son pourtour, à une petite distance dl du couvercle 5.The packaging shown in Figures 1 to 5 comprises an overpack 1 consisting of a flexible envelope which contains elongated flat products 2 prepackaged and stacked. The products 2 can for example be prepackaged food products, such as chewing gum tablets, cheese wafers, cookies or chocolate bars, or other prepackaged products such as smart cards. The flexible envelope 1 comprises a body 3 of generally parallelepipedal shape closed at its two ends, one constituting the bottom 4, the other constituting the cover 5, by folding and gluing the ends of the body 3 on themselves . The body 3 also has a tear strip 6 on its periphery, at a small distance dl from the cover 5.
Chaque produit 2, de forme rectangulaire, est préemballé dans un emballage primaire 7 qui comporte sur ses deux faces supérieure et inférieure une ligne de pré¬ rupture 8 parallèle à ses petits côtés et située à une distance d2 du couvercle 5 supérieure à dl. Dans l'exem¬ ple représenté, la ligne 8 est double et constituée de deux rangées d'entailles décalées l'une par rapport à l'autre d'un demi-pas.Each product 2, of rectangular shape, is prepackaged in a primary packaging 7 which has on its two upper and lower faces a pre-breaking line 8 parallel to its short sides and located at a distance d2 from the cover 5 greater than dl. In the example shown, line 8 is double and consists of two rows of notches offset from one another by a half step.
Pour la consommation des produits, on procède à 1'ouverture de 1'enveloppe 1 par déchirement de la bande 6 le long du pourtour du corps 3 et enlèvement complet et définitif du couvercle 5 et d'une portion attenante du corps 3. Cette opération dégage une extrémi¬ té des emballages primaires 7 contenus par l'enveloppe, comme représenté à la Figure 2.For the consumption of the products, the envelope 1 is opened by tearing the strip 6 along the periphery of the body 3 and complete and final removal of the cover 5 and of an adjoining portion of the body 3. This operation releases an extremi¬ ty of primary packaging 7 contained by the envelope, as shown in Figure 2.
Comme on le voit sur la Figure 4, l'extrémité 9 de chaque emballage primaire 7 adjacente au fond 4 est fixée à la face intérieure de ce dernier par une couche d'adhésif. De plus, les deux emballages primaires extrêmes, c'est-à-dire, dans la position à plat de ceux- ci qui est représentée, l'emballage primaire supérieur et l'emballage primaire inférieur, sont collés, respecti- vement par leur face supérieure et par leur face infé¬ rieure, à la face intérieure du suremballage 1 par leur région 10 voisine du fond 4, au moyen d'une couche du même adhésif que précédemment. En fonction de la force de l'adhésif utilisé, cette région 10 peut s'étendre plus ou moins loin vers le couvercle 5, sans toutefois dépasser la ligne de pré-rupture 8.As seen in Figure 4, the end 9 of each primary packaging 7 adjacent to the bottom 4 is fixed to the inner face of the latter by a layer of adhesive. In addition, the two extreme primary packaging, that is to say in the flat position thereof which is shown, the upper primary packaging and the lower primary packaging, are glued, respectively by their upper face and by their lower face, to the inner face of the overwrap 1 by their region 10 near the bottom 4, by means of a layer of the same adhesive as above. Depending on the strength of the adhesive used, this region 10 may extend more or less far towards the cover 5, without however cross the pre-rupture line 8.
Il est à noter que dans l'application du conditionnement d'une dizaine de tablettes de gomme à mâcher, le collage précité par les régions 9 et 10 des emballages primaires s'est révélé suffisant pour assurer de façon fiable le fonctionnement de l'emballage qui va être décrit ci-dessous, sans qu'il soit nécessaire de coller entre eux les emballages primaires par leurs faces latérales. On comprend cependant qu'un tel collage supplémentaire peut être réalisé, pour d'autres types de produits emballés, si cela s'avère nécessaire.It should be noted that in the application of the packaging of a dozen chewing gum tablets, the abovementioned bonding by the regions 9 and 10 of the primary packaging has been found to be sufficient to ensure the reliable functioning of the packaging. which will be described below, without the need to glue the primary packaging between them by their side faces. It is understood, however, that such additional bonding can be carried out, for other types of packaged products, if this proves necessary.
Lorsque 1'enveloppe 1 a été ouverte comme décrit plus en haut en regard de la Figure 2, l'utili¬ sateur saisit l'emballage primaire 7 supérieur par son extrémité exposée, en pinçant en même temps la tablette qu'il renferme, et tire l'ensemble dans le sens de la flèche F de la Figure 2.When the envelope 1 has been opened as described above with reference to FIG. 2, the user grasps the primary packaging 7 above by its exposed end, by pinching at the same time the tablet which it contains, and pull the assembly in the direction of arrow F in Figure 2.
Du fait que l'emballage primaire 7 est solidaire de 1'enveloppe 1 à son autre extrémité 9, cette action déchire 1'emballage primaire le long de la ligne de pré-rupture 8, et l'utilisateur a ainsi en main la partie 7A de l'emballage primaire, de longueur d2, qui était adjacente au couvercle 5, et la tablette 2, qui dépasse largement de cette partie 7A, comme représenté sur la Figure 3. Il peut alors mettre à la bouche la tablette sans la toucher avec les doigts, puis jeter la partie d'emballage primaire 7A.Because the primary packaging 7 is integral with the envelope 1 at its other end 9, this action tears the primary packaging along the pre-rupture line 8, and the user thus has in hand the part 7A of the primary packaging, of length d2, which was adjacent to the cover 5, and the tablet 2, which protrudes greatly from this part 7A, as shown in Figure 3. It can then put the tablet to the mouth without touching it with fingers, then discard the primary packaging part 7A.
En variante, si la distance d2 est inférieure à la largeur 1 des produits, il est même possible de remettre la partie 7A de l'emballage primaire dans l'autre partie 7B, restée solidaire de l'enveloppe 1, comme indiqué en 7C sur la Figure 4, ce qui supprime tout déchet partiel. Cette variante est toutefois plus appropriée lorsque la distance d2 est inférieure ou égale à la distance dl, car il est alors plus commode de remettre la partie 7A dans la partie 7B.As a variant, if the distance d2 is less than the width 1 of the products, it is even possible to place part 7A of the primary packaging in the other part 7B, which remains integral with the envelope 1, as indicated in 7C on Figure 4, which removes any partial waste. This variant is however more appropriate when the distance d2 is less than or equal to the distance dl, because it is then more convenient to return Part 7A to Part 7B.
On voit que, jusqu'à la fin de la consom¬ mation des tablettes 2, 1'enveloppe 1 conserve ses propriétés de réunion et de protection des produits et, en outre, conserve pratiquement sa forme extérieure. La consommation de chaque tablette s'effectue facilement, sans nécessité de défaire l'enveloppe primaire, et de façon hygiénique, et conduit à un déchet jetable minimal, ou même nul comme expliqué plus haut. On va maintenant décrire, en regard desIt can be seen that, until the consumption of the shelves 2 has ended, the casing 1 retains its properties for meeting and protecting the products and, moreover, practically retains its external shape. The consumption of each tablet is easy, without the need to undo the primary envelope, and hygienically, and leads to minimal disposable waste, or even zero as explained above. We will now describe, with regard to
Figures 6 à 9, un procédé de fabrication de l'emballage 1.Figures 6 to 9, a method of manufacturing the packaging 1.
A partir d'un rouleau d'une bande 11 préen¬ collée en continu avec la colle précitée sur sa face intérieure le long d'une zone marginale 12, représenté à la Figure 6, on fixe la bande de déchirure 6 à proxi¬ mité du bord 13 opposé à la zone 12, puis on découpe des feuilles 14, sur la face intérieure de chacune desquelles on dépose, partiellement sur la zone encollée, un empilement de produits 2 préemballés en 7, comme repré¬ senté à la Figure 7. La bande 11 porte également sur sa face extérieure des zones préencollées (non repré¬ sentées) servant à fermer l'emballage de façon classique. Pour ces zones comme pour la zone 12, on utilise par exemple une colle thermoréactivable forte.From a roll of a strip 11 preen¬ glued continuously with the aforementioned glue on its inner face along a marginal zone 12, shown in Figure 6, the tear strip 6 is fixed near from the edge 13 opposite the zone 12, then sheets 14 are cut, on the inner face of each of which there is deposited, partially on the glued zone, a stack of products 2 prepackaged at 7, as shown in FIG. 7. The strip 11 also carries on its outer face pre-glued areas (not shown) used to close the packaging in a conventional manner. For these zones as for zone 12, for example, a strong heat-activated adhesive is used.
La bande 11 peut être en papier ou en maté¬ riau complexe, par exemple constitué d'un film de matière plastique, d'une feuille de papier imprimé et d'une feuille d'aluminium, superposés et collés ensemble. La largeur de la bande 11 est supérieure à la longueur des produits à emballer.The strip 11 can be made of paper or a complex material, for example consisting of a plastic film, a sheet of printed paper and an aluminum sheet, superimposed and glued together. The width of the strip 11 is greater than the length of the products to be packaged.
On effectue ensuite le pliage de la feuilleThen we fold the sheet
14 selon une ébauche tubulaire du corps 3, comme indiqué à la Figure 8, et on colle l'un sur l'autre les bords de découpe de la feuille, ce qui ferme l'ébauche le long d'une génératrice; on replie ensuite sur elles-mêmes les zones marginales 12 et 13 de la feuille, qui constituent maintenant les extrémités du corps cylindrique 3, respectivement le fond 4 et le couvercle 5, comme indiqué à la Figure 9. Pendant ce pliage, la zone encollée 12 vient au contact de 1'extrémité correspondante 9 de chacun des emballages primaires 7 et des zones 10 des deux emballages primaires extrêmes.14 according to a tubular blank of the body 3, as shown in FIG. 8, and the cutting edges of the sheet are glued one on the other, which closes the blank along a generator; the marginal areas 12 and 13 of the sheet are then folded back on themselves, which now constitute the ends of the cylindrical body 3, respectively the bottom 4 and the cover 5, as shown in Figure 9. During this folding, the glued area 12 comes into contact with the corresponding end 9 of each of the primary packaging 7 and of the zones 10 of the two extreme primary packaging.
On effectue ensuite, par un dispositif non représenté de dissipation de chaleur aux deux extrémités de l'enveloppe, l'activation de la colle thermoréactiva- ble forte; ceci provoque simultanément le scellement des deux extrémités de l'enveloppe et l'adhérence des extrémités 9 des emballages 7 et des zones 10 des deux emballages primaires extrêmes au fond 4 et aux deux zones adjacentes de 1'enveloppe 1.Next, by means of a device (not shown) for dissipating heat at the two ends of the envelope, the activation of the strong thermoreactivable adhesive; this simultaneously causes the sealing of the two ends of the envelope and the adhesion of the ends 9 of the packages 7 and of the zones 10 of the two extreme primary packages to the bottom 4 and to the two adjacent zones of the envelope 1.
Si les zones 10 sont courtes, la chaleur ainsi dissipée est suffisante. Dans le cas contraire, il peut être nécessaire d'utiliser en outre une couronne chauffante (non représentée) entourant les zones 10.If the zones 10 are short, the heat thus dissipated is sufficient. Otherwise, it may be necessary to additionally use a heating ring (not shown) surrounding the zones 10.
Il est à noter que comme la majeure partie 7B des emballages primaires reste invisible dans 1'enveloppe 1, il n'est pas nécessaire de l'imprimer ou de la décorer. On peut même, dans certains cas, supprimer toute impression des emballages primaires, ce qui constitue une réduction notable du prix de revient de l'emballage.It should be noted that since the major part 7B of the primary packaging remains invisible in the envelope 1, it is not necessary to print or decorate it. It is even possible, in certain cases, to suppress all printing of the primary packaging, which constitutes a significant reduction in the cost price of the packaging.
Par ailleurs, on comprend que les lignes de pré-rupture 8 ne doivent pas affecter la bonne conser¬ vation des produits 2. Ainsi, ces lignes peuvent être constituées soit d'entailles traversant l'emballage primaire, soit de simples lignes d'affaiblissement non traversantes.Furthermore, it is understood that the pre-rupture lines 8 must not affect the good conservation of the products 2. Thus, these lines can consist either of notches passing through the primary packaging, or of simple weakening lines not through.
On décrira maintenant un autre mode de mise en oeuvre de l'invention, en regard des Figures 10 à 12. On effectue un empilement côte-à-côte de produits longs 2 préemballés en 7, par exemple de biscuits cylindriques préemballés, dont les emballages primaires 7 portent une ligne de pré-rupture 8. On trempe les emballages primaires dans un bac 15 contenant de la colle à l'état liquide, comme indiqué à la Figure 10; il s'agit par exemple ici de colle à froid activable par pression; cette opération a pour effet d'enduire de colle à froid 1'extrémité inférieure 9 et la région latérale adjacente 10 de chacun des produits préemballés. Cette enduction peut bien entendu être également obtenue par tout autre moyen, en particulier par préencollage externe des films destinés au préemballage unitaire de chacun des produits 2.Another mode of implementation of the invention will now be described, with reference to FIGS. 10 to 12. A stacking is carried out side by side with long products 2 prepackaged at 7, for example cylindrical prepackaged cookies, the primary packages of which carry a pre-break line 8. The primary packages are soaked in a container 15 containing glue in the liquid state, as indicated in Figure 10; it is for example here cold glue activatable by pressure; this operation has the effect of coating cold glue the lower end 9 and the adjacent lateral region 10 of each of the prepackaged products. This coating can of course also be obtained by any other means, in particular by external pre-gluing of the films intended for the unitary prepackaging of each of the products 2.
Par ailleurs, on réalise un corps d'enveloppe 3 de forme générale cylindrique, représenté à la FigureFurthermore, an envelope body 3 of generally cylindrical shape is produced, shown in FIG.
11, doté d'un fond inférieur 4 et ouvert vers le haut.11, with a lower bottom 4 and open upwards.
Ce corps d'enveloppe peut être réalisé par exemple en carton ou en matière plastique.This envelope body can be made for example of cardboard or plastic.
On fait pénétrer l'empilement de produits 2 dans l'enveloppe, comme indiqué à la Figure 11, en commençant par les extrémités enduites 9, 10 des pro¬ duits.The stack of products 2 is made to penetrate into the envelope, as shown in Figure 11, starting with the coated ends 9, 10 of the products.
On exerce entre le fond 4 et 1'extrémité supérieure des produits pré-emballés, au moyen de deux plateaux 16, 17, une pression suffisante pour activer la colle déposée aux extrémités 9 des produits au contact du fond 4 de l'enveloppe, comme indiqué à la Figure 12; on provoque ainsi 1'adhérence définitive des emballages primaires sur le fond de 1'enveloppe. L'ouverture supérieure de 1'enveloppe peut ensuite être refermée par un couvercle scellé non représenté. Ce peut être la mise en place de ce couvercle qui réalise l'activation de la colle.Is exerted between the bottom 4 and the upper end of the prepackaged products, by means of two plates 16, 17, sufficient pressure to activate the adhesive deposited at the ends 9 of the products in contact with the bottom 4 of the envelope, as shown in Figure 12; this causes the final adhesion of the primary packaging to the bottom of the envelope. The upper opening of the envelope can then be closed by a sealed cover, not shown. It may be the positioning of this cover which activates the adhesive.
On comprend que la préenduction des produits préemballés est compatible avec le mode d'emballage des Figures 6 à 9, et que, inversement, l'emballage de la Figure 12 peut être réalisé par préencollage de la face intérieure du fond 4. De plus, dans le cas des Figures 10 à 12, la colle utilisée peut être d'un type réacti- vable à chaud.It is understood that the pre-coating of prepackaged products is compatible with the method of packaging of Figures 6 to 9, and that, conversely, the packaging of Figure 12 can be achieved by pre-gluing the inner face of the bottom 4. In addition, in the case of Figures 10 to 12, the glue used can be of a hot reactive type.
En variante encore, l'adhérence des produits préemballés sur le fond de l'enveloppe peut s'obtenir par interposition d'un élément adhésif double face.In another variant, the adhesion of the prepackaged products to the bottom of the envelope can be obtained by interposing a double-sided adhesive element.
La Figure 13 illustre un autre mode de réalisation de l'invention, dans lequel le suremballage 1 est constitué par une boîte rigide en matière plasti¬ que, à couvercle 5 articulé en 18 sur le corps 3 de la boîte et à fond 4 alvéolé. Dans chaque alvéole 19 est collée ou soudée l'extrémité inférieure d'un tube rigide scellé 7 en matière plastique ou en verre contenant une dose 2 d'un produit liquide tel qu'un produit pharmaceu¬ tique, ou bien, en variante, un produit plus ou moins solide tel qu'une serviette en papier préhumidifiée. Chaque tube 7 présente près de son extrémité supérieure une ligne horizontale 8 de pré-rupture.FIG. 13 illustrates another embodiment of the invention, in which the overpack 1 is constituted by a rigid box made of plastic material, with a cover 5 hinged at 18 on the body 3 of the box and with a honeycombed bottom 4. In each cell 19 is bonded or welded the lower end of a rigid sealed tube 7 made of plastic or glass containing a dose 2 of a liquid product such as a pharmaceutical product, or alternatively, a more or less solid product such as a pre-moistened paper towel. Each tube 7 has near its upper end a horizontal line 8 of pre-rupture.
Ainsi, pour prélever une dose 2 par exemple au moyen d'une pipette, ou le produit plus ou moins solide correspondant, l'utilisateur saisit l'extrémité supérieure du tube 7 et brise ce tube le long de la ligne 8. Les autres produits 2 restent intacts et sont consom¬ més successivement de la même manière. Thus, to withdraw a dose 2 for example by means of a pipette, or the corresponding more or less solid product, the user grasps the upper end of the tube 7 and breaks this tube along the line 8. The other products 2 remain intact and are consumed successively in the same manner.
