Abstract

Package made of plastic material having the general shape of a container with a bottom and a lateral wall having at the opposite end to the said bottom an annular rim which extends towards the exterior of the said wall by a springing with a cover able to be brought above the container, in a first condition, and below the said container in another condition. The springing (15) is shaped at its end distant from the rim (14) according to a radial projecting reversal (20), with which is able to cooperate, by nesting, a rib of conjugated shape formed in the free rim of the cover (11). <IMAGE>

Description

L'invention a pour objet un dispositif d'emballage, notamment pour aliment à consommer chaud.The invention relates to a packaging device, in particular for food to be consumed hot.

Les nouvelles habitudes de consommation alimentaire rendent nécessaire de pouvoir disposer d'un emballage permettant de conditionner en usine, et dans de bonnes conditions d'asepsie, un aliment dont on souhaite qu'il possède une longue durée de conservation et qui, au cours de cette durée, puisse être consommé chaud sans avoir à être transvasé de son emballage d'origine, qu'il soit chauffé au bain-marie ou dans un four usuel ou dans un four à "micro-ondes". Si ce problème a déjà été abordé dans le cas d'un four à "micro-ondes" dans AU-B-0 565 000 c'est uniquement pour permettre l'échappement de vapeur lors de la cuisson, sans aborder le problème lié au fait que, quel que soit le mode de chauffage de l'aliment, surtout dans le cas du bain-marie ou du chauffage dans un four usuel, le contenant voit lui aussi sa température augmenter jusqu'à atteindre des valeurs (différentes il est vrai dans l'un et l'autre cas), mais qui peuvent être suffisamment élevées pour qu'il existe, à la sortie du four ou du bain marie, un risque de brûlure pour l'utilisateur, en particulier si celui-ci est un enfant.The new habits of food consumption make it necessary to be able to have a packaging allowing to condition in the factory, and in good asepsis conditions, a food which one wishes that it has a long shelf life and which, during this time, can be consumed hot without having to be transferred from its original packaging, whether heated in a water bath or in a conventional oven or in a "microwave" oven. If this problem has already been addressed in the case of a "microwave" oven in AU-B-0 565 000 it is only to allow the escape of steam during cooking, without addressing the problem associated with fact that, whatever the mode of heating the food, especially in the case of a water bath or heating in a conventional oven, the container also sees its temperature increase until reaching values (different it is true in both cases), but which can be high enough so that there is a risk of burns for the user when leaving the oven or bain-marie, in particular if the user is a child.

C'est, par conséquent, un but général de l'invention de fournir un dispositif d'emballage qui permette de résoudre dans son ensemble les problèmes exposés ci-dessus.It is therefore a general object of the invention to provide a packaging device which makes it possible to solve as a whole the problems set out above.

C'est, aussi, un but de l'invention de fournir un tel dispositif qui présente en outre de nombreux autres avantages, en particulier en ce qui concerne son coût de fabrication et sa facilité de mise en oeuvre.It is also an object of the invention to provide such a device which also has many other advantages, in particular as regards its manufacturing cost and its ease of implementation.

Le dispositif d'emballage en matière plastique selon l'invention, dont la forme générale est celle d'un récipient à fond et paroi latérale présentant à l'opposé dudit fond un bord annulaire qui se prolonge à l'extérieur du dispositif par une retombée avec un couvercle pouvant être rapporté au-dessus du récipient dans une première condition et au-dessous dudit récipient, dans une autre condition, est caractérisé en ce que ladite retombée est façonnée à son extrémité distante du bord, -lequel forme une plage de scellage d'un opercule de fermeture-, suivant un retour en saillie radiale avec lequel est propre à coopérer à emboîtement une nervure de forme conjuguée ménagée sur le bord libre du couvercle.The plastic packaging device according to the invention, the general shape of which is that of a container with a bottom and side wall having, opposite said bottom, an annular edge which extends outside the device by a drop with a cover which can be attached above the container in a first condition and below said container, in another condition, is characterized in that said drop is shaped at its end distant from the edge, which forms a sealing area for a closure cap-, following a radial projecting return with which is adapted to cooperate to interlock a rib of conjugate shape formed on the free edge of the cover.

En donnant à la retombée une hauteur sensiblement moitié de celle du dispositif d'emballage, le couvercle, qui permet de refermer l'ouverture du récipient après désoperculage, par exemple lorsque le contenu total de celui-ci n'est pas consommé, peut également être emboîté sous le dispositif, lequel repose alors sur un support par une surface de grande dimension qui en accroît la stabilité.By giving the fallout a height substantially half that of the packaging device, the lid, which allows the opening of the container to be closed after uncapping, for example when the total content of the latter is not consumed, can also be fitted under the device, which then rests on a support by a large surface which increases its stability.

Pour permettre au dispositif selon l'invention d'être mis en oeuvre, comme indiqué ci-dessus, aussi bien à l'aide d'un bain-marie, d'un four usuel, qu'à l'aide d'un four "micro-ondes", le matériau constitutif du dispositif est, d'une part, résistant aux températures normales qui peuvent être atteintes dans un four usuel et, d'autre part, choisi parmi les matières plastiques "transparentes" au rayonnement électro-magnétique.To allow the device according to the invention to be implemented, as indicated above, both using a water bath, a conventional oven, and using an oven "microwave", the material constituting the device is, on the one hand, resistant to normal temperatures which can be reached in a conventional oven and, on the other hand, chosen from plastics "transparent" to electromagnetic radiation .

Selon une autre caractéristique de l'invention, un ou des matériau(x) constitutif(s) du dispositif est(sont) un(des) matériau(x) du type "barrière", c'est-à-dire à feuille ou film avantageusement à plusieurs couches accolées les unes aux autres et choisies pour les propriétés qu'elles ont de faire obstacle au passage de fluide gazeux, permettant ainsi une longue conservation du produit enfermé dans l'emballage sans dégradation de ses qualités organoleptiques et de stérilité, etc...According to another characteristic of the invention, one or more material (s) constituting the device (s) is (are) one (s) material (s) of the "barrier" type, that is to say sheet or film advantageously with several layers placed side by side and chosen for the properties they have of obstructing the passage of gaseous fluid, thus allowing a long preservation of the product enclosed in the packaging without degradation of its organoleptic and sterility qualities, etc ...

Dans une forme de réalisation avantageuse du dispositif, le récipient est conformé suivant une coupelle et la matière plastique qui forme la coupelle est de préférence transulucide, le couvercle, par contre, étant en un matériau transparent différent de celui de ladite coupelle, les matières plastiques mises en oeuvre étant avantageusement choisies dans la famille des CPET (polyéthylène-téréphatalate cristallisé) dont on sait qu'ils peuvent résister à des températures de l'ordre de 250°C ou dans celle des EVOH (éthylvinyle alcool) ou des polyamides NMXD6 ou NYREF ou des PVdC.In an advantageous embodiment of the device, the container is shaped according to a cup and the plastic material which forms the cup is preferably transulucid, the cover, on the other hand, being made of a transparent material different from that of said cup, the plastics implemented advantageously being chosen from the family of CPETs (crystallized polyethylene terephatalate) which we know can withstand temperatures of the order of 250 ° C or from that of EVOH (ethyl vinyl alcohol) or NMXD6 polyamides or NYREF or PVdC.

L'invention sera bien comprise par la description qui suit, faite à titre d'exemple et en référence au dessin annexé dans lequel :

  • la figure 1 est une vue de dessus de l'ensemble du dispositif d'emballage ;
  • la figure 2 est une vue du dispositif sans son couvercle ;
  • la figure 3 est une vue en élévation du dispositif pour une première condition du couvercle avec un agrandissement partiel ;
  • la figure 4 est une vue analogue à celle de la figure 3, mais pour une autre condition du couvercle également avec un agrandissement partiel ;
  • la figure 5 est une vue en perspective éclatée du dispositif selon l'invention.
The invention will be better understood from the description which follows, given by way of example and with reference to the appended drawing in which:
  • Figure 1 is a top view of the entire packaging device;
  • Figure 2 is a view of the device without its cover;
  • Figure 3 is an elevational view of the device for a first condition of the cover with a partial enlargement;
  • Figure 4 is a view similar to that of Figure 3, but for another condition of the cover also with a partial enlargement;
  • Figure 5 is an exploded perspective view of the device according to the invention.

Un dispositif d'emballage selon l'invention, notamment pour le conditionnement d'un produit alimentaire à consommer chaud, comprend un contenant 10, représenté ici suivant une coupelle ou assiette, -cette indication n'ayant toutefois aucun caractère limitatif-, auquel est associé un couvercle 11 de forme en partie conjuguée de celle du contenant ou récipient 10. Ce dernier est avantageusement réalisé par formage et plus précisément thermoformage profond de matière plastique pour présenter un fond 12 et une paroi latérale 13 se terminant à l'opposé du fond par un bord annulaire 14 qui ménage une plage de thermoscellage d'un opercule 16 avec languette de préhension 16′ de fermeture du contenant 10.A packaging device according to the invention, in particular for packaging a food product to be consumed hot, comprises a container 10, represented here according to a dish or plate, this indication having however no limiting character, to which is associated with a cover 11 of shape partly conjugate with that of the container or container 10. The latter is advantageously produced by forming and more precisely deep thermoforming of plastic material to present a bottom 12 and a side wall 13 ending opposite the bottom by an annular edge 14 which provides a heat-sealing range of a cover 16 with gripping tab 16 ′ for closing the container 10.

Selon l'invention, le bord annulaire 14 est prolongé, à l'extérieur de la paroi 13, par une retombée 15 dont la hauteur est sensiblement égale à la moitié de la hauteur h qui est celle de la coupelle mesurée entre le fond 12 et la zone annulaire 14, ladite retombée s'étendant sensiblement parallèlement à la paroi 13, du moins dans la zone de cette dernière adjacente au bord annulaire 14.According to the invention, the annular edge 14 is extended, outside the wall 13, by a drop 15 whose height is substantially equal to half the height h which is that of the cup measured between the bottom 12 and the annular zone 14, said drop extending substantially parallel to the wall 13, at least in the zone of the latter adjacent to the annular edge 14.

A son extrémité libre la retombée 15 présente, conformément à l'invention, un retour en saillie radiale ou collerette 20 s'étendant dans un plan sensiblement perpendiculaire à l'axe XX de révolution du dispositif. Avec cette collerette 20 est propre à coopérer à emboîtement une gorge 21 ménagée au voisinage du bord libre 22 du couvercle 11 lequel, de forme conjuguée de celle de la retombée 15, est ici quelque peu à allure d'assiette avec une paroi latérale 25 et un fond 26 de relativement grande surface, la hauteur du couvercle étant légèrement supérieure à h/2. Une telle structure permet d'associer le couvercle 11 au contenant 10 de la façon montrée sur la figure 3, c'est-à-dire en laquelle le couvercle est au-dessus du dispositif, soit pour protéger l'opercule 16 aussi longtemps que celui-ci est présent, soit pour refermer le contenant 10 après désoperculage. Elle permet également d'associer le couvercle 11 au contenant 10 de la façon montrée sur la figure 4, en laquelle le couvercle est au-dessous du dispositif, procurant à ce dernier une excellente stabilité et fournissant un "écran" thermique lorsque le dispositif d'emballage et son contenu ont été préalablement chauffés, sans couvercle.At its free end the dropout 15 has, in accordance with the invention, a radial projecting return or flange 20 extending in a plane substantially perpendicular to the axis XX of revolution of the device. With this flange 20 is able to cooperate in fitting a groove 21 formed in the vicinity of the free edge 22 of the cover 11 which, in shape combined with that of the drop 15, is here somewhat in attitude with a side wall 25 and a bottom 26 of relatively large area, the height of the cover being slightly greater than h / 2. Such a structure makes it possible to associate the cover 11 with the container 10 in the manner shown in FIG. 3, that is to say in which the cover is above the device, that is to protect the cover 16 as long as it is present, either to close the container 10 after uncapping. It also makes it possible to associate the cover 11 with the container 10 in the manner shown in FIG. 4, in which the cover is below the device, providing the latter with excellent stability and providing a thermal "screen" when the device d The packaging and its contents have been previously heated, without a lid.

Pour permettre au dispositif d'être mis en oeuvre, aussi bien à l'aide d'un bain-marie, d'un four usuel (mais alors sans couvercle) ou à l'aide d'un four "micro-ondes" (sans désoperculage si le matériau de l'opercule 16 est convenablement choisi) ou après désoperculage et alors remise en place éventuelle du couvercle 11 au-dessus du contenant 10, le ou les matériau(x) constitutif(s) du contenant 10 et du couvercle 11 est(sont), d'une part, résistant(s) aux températures qui peuvent être atteintes dans un four usuel jusqu'à 250°C et, d'autre part, choisi(s) parmi les matières plastiques "transparentes" au rayonnement électromagnétique.To allow the device to be implemented, as well using a double boiler, a conventional oven (but then without a cover) or using a "microwave" oven ( without uncapping if the material of the lid 16 is suitably chosen) or after uncapping and then possibly replacing the lid 11 above the container 10, the material (s) constituting the container 10 and the lid 11 is (are), on the one hand, resistant (s) to temperatures which can be reached in a conventional oven up to 250 ° C and, on the other hand, chosen (s) from "transparent" plastics at electromagnetic radiation.

Des matières plastiques appropriées pour ce faire peuvent être choisies dans la famille des CPET (polyéthylène-téréphtalate cristallisé) dont on sait qu'elles peuvent résister à des températures de l'ordre de 250°C et qui peuvent être mises en forme par thermoformage profond.Plastics suitable for this can be chosen from the family of CPETs (crystallized polyethylene terephthalate) which we know can withstand temperatures of the order of 250 ° C and which can be shaped by deep thermoforming .

D'autres matériaux appropriés sont ceux choisis dans la famille des EVOH (éthylvinyle alcool) ou des PVdC ou des polyamides, par exemple ceux connus sous les noms commerciaux de NMXD6 ou NYREF.Other suitable materials are those chosen from the family of EVOHs (ethylvinyl alcohol) or PVdCs or polyamides, for example those known under the trade names of NMXD6 or NYREF.

Complémentairement, le ou les matériau(x) constitutif(s) du dispositif présente(nt) des propriétés de "barrière" faisant obstacle aux échanges gazeux et permettent d'assurer au produit enfermé dans le contenant 10 (traité par exemple par stérilisation) une très longue durée de conservation, qui peut être de l'ordre d'un an pour un dispositif gardé à température ambiante normale.In addition, the material (s) constituting the device (s) has (s) "barrier" properties which prevent gas exchange and make it possible to ensure that the product enclosed in the container 10 (treated for example by sterilization) a very long shelf life, which can be around a year for a device kept at normal room temperature.
