Description

1Emballage de produit consommable
L'invention se rapporte à un emballage de produit consommable, notaient de produit alimentaire! du type comportant un opercule mince rapporté de façon étanche sur l'ouverture et destiné à être enlevé par le consommateur lui-même. 1 Consumable product packaging
The invention relates to a consumable product packaging, noted food product! of the type comprising a thin cover attached in a sealed manner to the opening and intended to be removed by the consumer himself.

L'invention concerne plus particulièrement. un perfectionnement rendant irréversible l'ouverture frauduleuse, voire malveillante, d'un tel opercule et donnant donc au consommateur la certitude que le produit qu'il achète n'est pas pollué ou avarié. The invention relates more particularly. an improvement making the fraudulent or even malicious opening of such a cover irreversible and therefore giving the consumer the certainty that the product he is buying is not polluted or damaged.

Il est connu de conditionner certains produits alimentaires comme le lait en poudre, le cacao ou le café, en emballage rigide ou semi-rigide dont l'ouverture est fermée par un opercule mince et souple, en aluminium ou matière plastique ou en matériau composite (juxtaposition d'une feuille de matière plastique et d'une feuille d'aluminium). Cet opercule a une double fonction: il contribue à assurer une bonne conservation du produit. It is known practice to package certain food products, such as powdered milk, cocoa or coffee, in rigid or semi-rigid packaging, the opening of which is closed by a thin and flexible cover, made of aluminum or plastic or a composite material ( juxtaposition of a plastic sheet and an aluminum sheet). This cover has a dual function: it helps to ensure good preservation of the product.

pendant la période de stockage et il permet au consommateur de vérifier que le produit n'a pas été pollué ou entamé.during the storage period and allows the consumer to check that the product has not been polluted or damaged.

Dans les emballages connus de ce type, l'opercule mince est thermoscellé ou autrement collé sur un rebord plat du corps de boite, s'étendant le long du périmètre de l'ouverture. Ce type d'emballage donne, en principe, toute satisfaction, mais dans un certain nombre de cas, rares mais parfois dramatiques1 on a pu observer que l'opercule avait été décollé partiellement, puis recollé sans que l'opération ne laisse de trace visible. On a ainsi pu mettre en évidence que l'ouverture frauduleuse pouvait être pratiquée en appliquant un fer â repasser ou un objet chauffant analogue sur la zone thermoscellée et en refermant l'opercule da la même façon. Des malfaiteurs ou déséquilibrés sont ainsi parvenus à souiller, voire empoisonner délibérément des produits alimentaires ainsi emballés.In known packages of this type, the thin lid is heat sealed or otherwise glued to a flat rim of the can body, extending along the perimeter of the opening. This type of packaging is, in principle, completely satisfactory, but in a certain number of rare but sometimes dramatic cases1 it has been observed that the seal had been partially peeled off, then re-glued without the operation leaving any visible trace. . It was thus possible to demonstrate that the fraudulent opening could be made by applying an iron or a similar heating object to the heat-sealed zone and by closing the cover in the same way. Criminals or imbalances have thus managed to defile or even deliberately poison food products packaged in this way.

L'invention apporte une solution à ce type de problème en proposant un emballage du genre décrit ci-dessus, mais dont l'opercule ne puisse être décollé de manière réversible. The invention provides a solution to this type of problem by providing a package of the type described above, but the cover of which cannot be removed in a reversible manner.

Dans cet esprit, l'invention, concerne donc principalement un emballage de produit consommable, notamment un produit alimentaire, du type comportant une boite munie d'une ouverture fermée par un opercule mince thermoscellé ou autrement collé sur le bord de ladite ouverture, caractérisé en ce que ce bord est arrondi et que ledit opercule adhère sur une surface annulaire substantielle de ce bord arrondi. In this spirit, the invention therefore mainly relates to a packaging for a consumable product, in particular a food product, of the type comprising a box provided with an opening closed by a thin cover heat-sealed or otherwise glued to the edge of said opening, characterized in that this edge is rounded and that said cover adheres to a substantial annular surface of this rounded edge.

Dans le cas d'un emballage métallique, le bord arrondi est avantageusement réalisé par un croulé de l'extrémité du corps de boite, opération bien connue dans la technique. In the case of a metal packaging, the rounded edge is advantageously produced by a crumbling of the end of the box body, an operation well known in the art.

Enfin, selon une autre particularité avantageuse de l'invention, la surface annulaire de la zone thermoscellée s'étend vers l'intérieur du corps de boite à partir d'un plan tangent audit bord arrondi. L'opercule est ainsi mieux tendu et il ne peut pratiquement être décollé sans se déchirer. Finally, according to another advantageous feature of the invention, the annular surface of the heat-sealed zone extends towards the interior of the box body from a plane tangent to said rounded edge. The cover is thus better stretched and it can practically be unstuck without tearing.

L'invention sera mieux comprise et d'autres avantages de celle-ci apparaîtront plus clairement à la lumière de la description qui va suivre d'un mode de réalisation d'un emballage métallique conforme à son principe, donnée uniquement à titre d'exemple et faite en référence au dessin annexé dans lequel:
- la figure unique représente une vue partielle en coupe de la partie supérieure d'un emballage métallique conforme à l'invention ainsi que la partie inférieure d'un autre emballage métallique identique, pour illustrer la façon dont de tels emballages peuvent être empilés.The invention will be better understood and other advantages thereof will appear more clearly in the light of the following description of an embodiment of a metal packaging in accordance with its principle, given solely by way of example. and made with reference to the attached drawing in which:
- the single figure shows a partial sectional view of the upper part of a metal packaging according to the invention as well as the lower part of another identical metal packaging, to illustrate the way in which such packaging can be stacked.

L'emballage 11, ici du type métallique, comprend un corps de boite 12, ici cylindrique, muni à l'une de ses extrémités d'un fond 13, serti de façon classique, un couvercle 14, ici également métallique, et un opercule mince 15 obturant (avant consommation du produit) l'ouverture 16 définie à l'autre extrémité du corps de boite. The packaging 11, here of the metallic type, comprises a box body 12, here cylindrical, provided at one of its ends with a base 13, crimped in a conventional manner, a cover 14, here also metallic, and a cover thin 15 sealing (before consumption of the product) the opening 16 defined at the other end of the box body.

Le couvercle 14 comporte une jupe latérale approximativement cylindrique, muni de six nervures internes 18 coopérant avec six nervures externes 19 du corps de boite 12 pour permettre une fermeture relativement hermétique, pendant la durée de consommation du produit. La position oblique et la forme de ces nervures sur le corps de boite permet l'ouverture ou la.fermeture du couvercle par une faible rotation. Un rehord annulaire en saillie 20 s'étend aussi le long du périmètre circulaire du couvercle; le diamètre extérieur de ce rebord est légèrement inférieur au diamètre interne du fond 13, comme illustré, pour permettre l'empilage de boites semblables. The cover 14 comprises an approximately cylindrical lateral skirt, provided with six internal ribs 18 cooperating with six external ribs 19 of the box body 12 to allow a relatively hermetic closure, during the period of consumption of the product. The oblique position and the shape of these ribs on the box body allows the opening or la.feture of the cover by a slight rotation. A projecting annular flange 20 also extends along the circular perimeter of the cover; the outside diameter of this rim is slightly less than the inside diameter of the bottom 13, as illustrated, to allow the stacking of similar boxes.

Selon l'invention, l'opercule 15 est thermoscellé ou autrement collé sur un bord arrondi 22 du corps de boîte, délimitant l'ouverture 16, de sorte que ledit opercule adhère sur une surface annulaire externe substantielle dudit bord arrondi. Dans la pratique, l'opercule peut être appliqué sur ledit bord arrondi par un outil chauffant conformé pour présenter une creusure annulaire de forme et dimensions adéquates, avec interposition, à la périphérie, d'une couche de matière plastique thermofusible, formant colle, connue en soi. Comme représenté, la zone d'adhérence s'étend, suivant une coupe diamétrale du. corps de boîte, le long d'un arc AB, la surface annulaire définissant la zone d'adhérence ayant ici la forme d'une partie de tore.De façon simple, le bord arrondi 22 est matérialisé par un simple "roulé" de l'extrémité du corps de boite 12, opération bien connue dans la technique. ri s'agit, de préférence, d'un roulé intérieur, comme représenté, ce qui simplifie la forme du couvercle 14 pour permettre l'empilage. De plus, il est à noter que le thermoscellage est tel que la surface annulaire torique précitée s'étende vers l'intérieur du corps de boite (partie correspondant à l'arc AC) à partir d'un plan P tangent au bord arrondi 22. According to the invention, the lid 15 is heat sealed or otherwise glued to a rounded edge 22 of the box body, delimiting the opening 16, so that said lid adheres to a substantial outer annular surface of said rounded edge. In practice, the cap may be applied to said rounded edge by a heating tool shaped to present an annular recess of suitable shape and dimensions, with the interposition, at the periphery, of a layer of hot-melt plastic material, forming an adhesive, known in itself. As shown, the adhesion zone extends, following a diametrical section of the. box body, along an arc AB, the annular surface defining the adhesion zone here having the shape of a part of a torus. In a simple way, the rounded edge 22 is materialized by a simple "roll" of the end of the box body 12, an operation well known in the art. ri is preferably an inner roll, as shown, which simplifies the shape of the cover 14 to allow stacking. In addition, it should be noted that the heat sealing is such that the aforementioned toric annular surface extends towards the inside of the box body (part corresponding to the arc AC) from a plane P tangent to the rounded edge 22 .

Cette particularité permet de tendre l'opercule au moment du thermoscellage, voire de l'étirer légèrement. On évite ainsi la formation de plis et il devient impossible de décoller I'opercule, même partiellement, sans le déchirer.This feature makes it possible to stretch the lid when heat-sealing, or even to stretch it slightly. This prevents the formation of folds and it becomes impossible to peel off the cover, even partially, without tearing it.

Il apparaît clairement que l'invention constitue une parade efficace contre toute tentative d'ouverture de l'opercule, suivi d'une dissimulation, en utilisant par exemple un dispositif chauffant quelconque tel qu'un fer à repasser, dans la mesure où il devient impossible de chauffer de façon convenable la totalité de la zone d'adhérence courbe. En outre, il apparaît que cette dernière est plus--large qu'une zone plane, toutes choses égales par ailleurs, en raison même de l'arrondi. Le thermoscellage est donc en soi plus résistant. It clearly appears that the invention constitutes an effective countermeasure against any attempt to open the cover, followed by concealment, for example by using any heating device such as an iron, insofar as it becomes impossible to adequately heat the entire curved grip area. In addition, it appears that the latter is wider than a flat area, all other things being equal, by the very reason of the rounding. Heat sealing is therefore inherently more resistant.

Bien entendu, l'invention n'est pas limitée aux emballages métalliques. Elle s'applique à toutes sortes de boîtes, dans les matériaux les plus divers (matière plastique notamment) pourvu que la rigidité de la boite soit suffisante pour supporter l'opération de thermoscellage. Of course, the invention is not limited to metal packaging. It applies to all kinds of boxes, in the most diverse materials (plastic in particular) provided that the rigidity of the box is sufficient to withstand the heat-sealing operation.
