Abstract
Description
Le domaine de l'invention est celui du conditionnement de produits alimentaires. Plus précisément, l'invention concerne un emballage pour le conditionnement d'un aliment ou d'une préparation alimentaire destinée à être réchauffé ou cuit, notamment dans un four micro-ondes, l'emballage comprenant un matériau souple présentant une zone de scellement.The field of the invention is that of product packaging food. More specifically, the invention relates to packaging for the packaging of a food or a food preparation intended to be reheated or cooked, especially in a microwave oven, the packaging comprising a flexible material having a sealing area.
Dans le domaine de l'invention, il est classique de proposer des aliments ou des plats préparés dans des sachets formés d'une ou de plusieurs feuilles souples, ou encore dans des barquettes fermées par un opercule formé d'une feuille d'une matériau souple.In the field of the invention, it is conventional to propose food or dishes prepared in sachets formed from one or more leaves flexible, or in trays closed by a lid formed by a sheet of flexible material.
Certains de ces produits sont destinés à être réchauffés ou cuits avant consommation, différents moyens de réchauffage étant généralement envisageables, et notamment le réchauffage au mico-ondes.Some of these products are intended to be reheated or cooked before consumption, different means of reheating generally being possible, and in particular reheating with microwave.
Le conditionnement de ces aliments ou plats préparés est réalisé de façon étanche, ce qui est susceptible d'entraíner une augmentation de pression plus ou moins importante au sein de l'emballage au cours du réchauffage, en fonction de la puissance et de la durée de ce réchauffage.The packaging of these foods or prepared meals is carried out in a way waterproof, which is likely to cause a pressure increase more or less important in the packaging during reheating, depending on the power and duration of this reheating.
Deux conséquences peuvent le cas échéant être déplorées.Two consequences can be deplored if necessary.
En premier lieu, l'augmentation de la pression à l'intérieur de l'emballage peut atteindre un niveau tel qu'elle provoque purement et simplement l'explosion de l'emballage ainsi que la dispersion de son contenu. Une telle conséquence est bien entendue inacceptable de par le désagrément qu'elle suscite pour le consommateur.First, the increase in pressure inside the packaging can reach such a level that it simply causes the explosion packaging and the dispersion of its contents. One such consequence is of course unacceptable because of the inconvenience it causes for the consumer.
Cette conséquence peut bien entendu être évitée en ouvrant partiellement l'emballage, évitant ainsi la montée en pression à l'intérieur de celui-ci. Toutefois, l'ouverture de ces emballages n'est pas aisée et peut aboutir, dans certains cas, à une déchirure de l'emballage plus importante que celle souhaitée par le consommateur, entraínant éventuellement un déversement du contenu hors de l'emballage. This consequence can of course be avoided by partially opening the packaging, thus avoiding the pressure build-up inside it. However, opening these packages is not easy and can lead, in in some cases, a tear in the packaging greater than that desired by the consumer, possibly resulting in a spill of the content outside of the packaging.
Dans le cas où l'augmentation de la pression ne provoque pas l'éclatement de l'emballage, une autre conséquence peut alors apparaítre.In case the increase in pressure does not cause bursting of the packaging, another consequence may then appear.
En effet, la pression dans l'emballage est telle que, au moment de l'ouverture de celui- par le consommateur, ce dernier peut subir, avec plus ou moins de dommages, des projections de vapeur brûlante et éventuellement d'une partie du contenu (par exemple une sauce).The pressure in the packaging is such that, when the opening of this by the consumer, the latter may suffer, with more or less damage, projections of hot steam and possibly part of the contents (for example a sauce).
Une telle conséquence est elle aussi inacceptable.Such a consequence is also unacceptable.
Pour remédier à ces inconvénients, il a été proposé de rapporter sur certains emballages des valves d'obturation qui s'ouvrent automatiquement lorsque la pression dans l'emballage atteint un niveau prédéterminée.To remedy these drawbacks, it has been proposed to report on some packages of shutter valves that open automatically when the pressure in the package reaches a predetermined level.
Une telle solution apparaít satisfaisante en termes de résultat. Cependant, de telles valves rendent plus complexe la fabrication de l'emballage, et augmente le prix de revient de celui-ci.Such a solution appears satisfactory in terms of result. However, such valves make packaging more complex, and increase the cost price of it.
L'invention a pour objectif de pallier les inconvénients de l'art antérieur.The invention aims to overcome the drawbacks of the prior art.
Plus précisément, l'invention a pour objectif de proposer un emballage d'une préparation alimentaire destinée à être réchauffée qui évite une augmentation excessive de la pression à l'intérieur de l'emballage pendant le réchauffage.More specifically, the invention aims to provide packaging of a food preparation intended to be reheated which avoids excessive pressure inside the packaging during reheating.
L'invention a également pour objectif de fournir un tel emballage qui soit simple et peu coûteux à réaliser.The invention also aims to provide such packaging which is simple and inexpensive to make.
Notamment, l'invention a pour objectif de fournir un tel emballage qui peu être réalisé à partir d'un film polymère pouvant être utilisé avec des machines classiques, ne nécessitant aucun investissement spécifique.In particular, the invention aims to provide such packaging which can be made from a polymer film that can be used with conventional machines, requiring no specific investment.
L'invention a aussi pour objectif de fournir un tel emballage qui soit sûr et pratique d'utilisation pour le consommateur.The invention also aims to provide such packaging which is safe and practical for the consumer.
Ces objectifs ainsi que d'autres qui apparaítront par la suite, sont atteints grâce à l'invention qui a pour objet un emballage pour le conditionnement d'un aliment ou d'une préparation alimentaire destinée à être réchauffée ou cuit, notamment à l'aide d'un four à micro-ondes, du type comprenant au moins une feuille en matériau souple présentant au moins une zone de scellement, caractérisé en ce que ladite zone de scellement est enduite partiellement d'un matériau à effet limitatif de la propagation de la chaleur de scellement répartie sur ladite zone de façon à ménager au moins un ílot dépourvu dudit matériau à effet limitatif.These objectives and others which will appear later are achieved thanks to the invention which relates to a packaging for the packaging of a food or a food preparation intended to be reheated or cooked, in particular using a microwave oven, of the type comprising at least one sheet of flexible material having at least one sealing zone, characterized in that said sealing zone is partially coated with a material with limiting effect on the spread of distributed sealing heat on said zone so as to provide at least one island devoid of said material to limiting effect.
Ainsi, on obtient un emballage comportant une zone de scellement de moindre résistance tout en étant étanche. En d'autres termes, l'étanchéité est assurée par des points (ílots) de scellement traditionnels, tandis que la résistance du scellement est diminuée en d'autres endroits de la zone de scellement.Thus, a package is obtained comprising a sealing zone of less resistance while being waterproof. In other words, tightness is ensured by traditional sealing points (islands), while the resistance sealing is decreased elsewhere in the sealing area.
De cette façon, on crée des zones de "dé-scellage" progressif. En effet, les ílots de scellage traditionnels maintiennent l'étanchéité de l'emballage, jusqu'à la pression à l'intérieur de l'emballage atteigne un niveau prédéterminée, à partir duquel les zones enduites matériau à effet limitatif du scellement cèdent progressivement à la pression, créant une ouverture dans l'emballage qui laisse échapper vers l'extérieur un flux de vapeur (ou autre gaz).In this way, progressive "de-sealing" zones are created. Indeed, the traditional sealing islands maintain the tightness of the packaging, until the pressure inside the package reaches a predetermined level, from from which the zones coated material with a limiting effect of the seal yield gradually under pressure, creating an opening in the packaging which leaves escape to the outside a flow of vapor (or other gas).
Cette ouverture due à l'augmentation de la pression peut intervenir de façon similaire dans le cas où l'emballage selon l'invention renferme un aliment fermentescible, susceptible d'entraíner la formation d'un gaz, y compris en l'absence de chauffage.This opening due to the increase in pressure can occur from similarly in the case where the packaging according to the invention contains a food fermentable, likely to cause the formation of a gas, including the absence of heating.
L'invention évite donc tout risque d'éclatement, voire d'explosion, de l'emballage. L'ouverture de l'emballage ayant déjà eu lieu au cours du réchauffage, l'invention évite également au consommateur de subir des projections du contenu au moment de l'ouverture de l'emballage contrairement à certains emballages de l'art antérieur.The invention therefore avoids any risk of bursting, or even explosion, of packaging. The opening of the packaging having already taken place during the reheating, the invention also prevents the consumer from undergoing projections of the content at the time of opening the packaging unlike some packaging of the prior art.
L'invention s'applique tout aussi bien à des emballages renfermant des préparations alimentaires destinées à être réchauffées, qu'à des aliments, éventuellement non composés, crus ou cuits.The invention applies equally well to packaging containing food preparations intended to be reheated, only to food, possibly not composed, raw or cooked.
Selon une solution préférée de l'invention, ladite zone de scellement présente une pluralité d'ílots dépourvus dudit matériau à effet limitatif.According to a preferred solution of the invention, said sealing zone presents a plurality of islands devoid of said material with limiting effect.
Selon une solution avantageuse, lesdits ílots s'étendent chacun sur une surface comprise entre environ 0,25 mm2 et environ 25 mm2. According to an advantageous solution, said islands each extend over a surface between approximately 0.25 mm2 and approximately 25 mm2.
Bien entendu, d'autres dimensions des ílots peuvent être envisagées dans d'autres modes de réalisation, sans sortir du cadre de l'invention.Of course, other dimensions of the islands can be considered in other embodiments, without departing from the scope of the invention.
Selon une solution préférentielle, ladite zone de scellement comprend entre 1 et 100 ílots par cm2. Préférentiellement, ladite zone de scellement comprend 25 ílots par cm2According to a preferred solution, said sealing zone comprises between 1 and 100 islets per cm2. Preferably, said sealing zone includes 25 islands per cm2
Le choix de la répartition et/ou de la quantité du matériau à effet limitatif sera fonction de la qualité de la soudure recherchée. On pourra notamment prévoir un nombre d'ílots au cm2 qui assure de maintenir l'étanchéité de l'emballage pendant une durée prédéterminée pour permettre une cuisson ou un réchauffage de type "à la vapeur" ou "cocotte minute".The choice of the distribution and / or the quantity of the material with limiting effect will depend on the quality of the weld sought. We can in particular provide a number of islands per cm2 which ensures that the watertightness of the packaging for a predetermined period to allow cooking or reheating type "steam" or "pressure cooker".
Avantageusement, lesdits ílots présentent une forme appartenant au groupe suivant :
- ronde ;
- ovoïde ;
- carrée ;
- triangle ;
- en étoile.
- round;
- ovoid;
- square;
- triangle;
- in a star.
Selon une autre solution avantageuse, lesdits ílots présentent essentiellement une forme de losange.According to another advantageous solution, said islands have basically a diamond shape.
Avantageusement, ledit matériau à effet limitatif de la propagation de la chaleur au scellage comprend au moins une laque et/ou au moins une enduction.Advantageously, said material with a limiting effect on the propagation of the heat sealing includes at least one lacquer and / or at least one coating.
Préférentiellement, ledit matériau souple comprend au moins un des matériaux appartenant au groupe suivant :
- film polyoléfine co-extrudé ;
- film polyoléfine mono ;
- film polyoléfine bi-orienté ;
- film polyoléfine complexé ;

- aluminium.
- co-extruded polyolefin film;
- mono polyolefin film;
- bi-oriented polyolefin film;
- complexed polyolefin film;
- paper;
- aluminum.
L'emballage pourra être réalisé dans tout autre matériau souple, complexé ou non, scellable, dans d'autres modes de réalisation, sans sortir du cadre de l'invention.The packaging may be made of any other flexible, complexed material or not, sealable, in other embodiments, without departing from the scope of the invention.
Selon une première approche, ledit matériau souple est conformé en sachet présentant au moins deux lèvres délimitant une zone d'ouverture/fermeture dudit emballage.According to a first approach, said flexible material is shaped as sachet with at least two lips delimiting an area opening / closing of said packaging.
Selon un premier mode de réalisation de cette première approche, ledit matériau à effet limitatif est déposé sur ladite zone de scellement d'une seule desdites lèvres dudit sachet.According to a first embodiment of this first approach, said material with a limiting effect is deposited on said sealing area with a single said lips of said sachet.
Selon un deuxième mode de réalisation de cette première approche, ledit matériau à effet limitatif est déposé sur ladite zone de scellement de chacune desdites deux lèvres dudit sachet.According to a second embodiment of this first approach, said limiting effect material is deposited on said sealing zone of each of said two lips of said sachet.
Avantageusement, ledit sachet comprend au moins un soufflet de fond.Advantageously, said bag comprises at least one bottom bellows.
Un tel soufflet de fond permet au consommateur de déposer le sachet dans l'appareil de réchauffage en le maintenant en station debout. On note que le sachet pourra également ou alternativement présenter un ou plusieurs soufflets latéraux de façon à améliorer la présentation de l'emballage.Such a bottom bellows allows the consumer to deposit the sachet in the reheater while keeping it standing. We note that the bag can also or alternatively present one or more bellows side to improve the presentation of the packaging.
Bien entendu, de tels soufflets sont optionnels et l'emballage pourra en être dépourvu selon un autre mode de réalisation envisageable.Of course, such bellows are optional and the packaging may be lacking according to another possible embodiment.
Selon une deuxième approche, ledit matériau souple forme un opercule destiné à être rapporté sur un réceptacle de type barquetteAccording to a second approach, said flexible material forms a cover intended to be attached to a receptacle of the tray type
L'invention concerne également un film pour la réalisation d'un emballage tel que décrit précédemment, caractérisé en ce qu'il présente au moins une zone enduite partiellement d'un matériau à effet limitatif de la propagation de la chaleur de scellement répartie sur ladite zone de façon à ménager au moins un ílot dépourvu dudit matériau à effet limitatifThe invention also relates to a film for making a packaging as described above, characterized in that it has at least an area partially coated with a material limiting the spread sealing heat distributed over said area so as to provide at least an island devoid of said limiting-effect material
D'autres caractéristiques et avantages de l'invention apparaítront plus clairement à la lecture de la description de plusieurs modes de réalisation préférentiels de l'invention, donnés à titre d'exemples illustratifs et non limitatifs, et des dessins annexés parmi lesquels :

En référence à la figure 1, un emballage, pour le conditionnement d'une
préparation alimentaire 1 destinée à être réchauffée, comprend un fourreau 2
réalisé en un matériau souple (film polyoléfine co-extrudé, mono ou bi-orienté,
ou complexé).With reference to FIG. 1, a package, for packaging a
On note que selon un autre mode de réalisation envisageable, l'emballage pourrait être constitué d'une seule feuille (obtenue à partir d'un film) repliée sur elle-même et scellé sur trois de ses côtés afin de constituer un sachet renfermant une préparation alimentaire. Il pourrait encore être constitué de deux feuilles souples soudées entre elles, comme cela va être décrit par la suite.Note that according to another possible embodiment, the packaging could consist of a single sheet (obtained from a film) folded over itself and sealed on three of its sides in order to constitute a sachet containing a food preparation. It could still consist of two leaves flexible welded together, as will be described later.
Selon le présent mode de réalisation, chaque feuille 2 présente deux
lèvres 21 scellées entre elles, une partie de la zone de scellement 20 étant enduite
d'une laque 22, formant matériau à effet limitatif de la propagation de la chaleur
de scellement (le scellement étant de moindre résistance en cette zone enduite de
laque), tandis qu'une pluralité d'ílots 23 sont dépourvus de cette laque.According to the present embodiment, each
Le nombre d'ílots représenté sur la figure 1 est illustré à titre indicatif, et sera préférentiellement de 25 ílots par cm2, chaque ílot s'étendant sur une surface d'environ 1 mm2.The number of islands shown in FIG. 1 is illustrated for information only, and will preferably be 25 islands per cm2, each island extending over a surface about 1 mm2.
Tel que cela apparaít, les ílots présentent dans le cas présent une forme de losange, mais pourront de façon similaire présenter une forme carrée, ronde ou ovale, tel que respectivement illustré par les figures 3, 4 et 5, ou encore toute autre forme appropriée. As it appears, the islands present in the present case a form of rhombus, but may similarly have a square, round or oval, as respectively illustrated by FIGS. 3, 4 and 5, or even any other suitable form.
Ainsi, pendant le chauffage de l'emballage et de la préparation
alimentaire qu'il renferme, la zone enduite de la laque 22 cède, après un temps
prédéterminée, à la pression qui s'élève à l'intérieur de l'emballage, ménageant
soit des passages entre les ílots 23 pour laisser échapper de la vapeur d'eau, soit
un déscellage complet de la zone 20.So, during the heating of the packaging and the preparation
food it contains, the lacquered
Selon un autre mode de réalisation illustré par la figure 2, l'emballage
présente trois soudures 24 intégrant des zones de scellement 20, enduites d'une
laque, tandis que des ílots 23 sont dépourvus de cette laque.According to another embodiment illustrated in Figure 2, the packaging
has three
Les zones de scellement 20 peuvent donc présenter une forme de triangle
ou être prévus sous forme de stries droites ou inclinées.The sealing
On note également qu'un tel emballage combine des zones de scellement selon l'invention et une zone de scellement pleine.It is also noted that such a packaging combines sealing zones according to the invention and a full sealing area.
L'emballage selon le mode de réalisation illustré par la figure 6, est
obtenue à partir de deux feuilles d'un matériau souple (les deux feuilles pouvant
également être réalisées en des matériaux différents) scellées entre elles sur
chacun de leur côté par leur lèvres respectives 21.The packaging according to the embodiment illustrated in FIG. 6 is
obtained from two sheets of flexible material (the two sheets can
also be made of different materials) sealed together on
each on their side by their
De façon similaire aux modes de réalisation décrits précédemment, cet
emballage présente des zones de scellement 20 enduites d'une laque 22, tandis
que des ílots 23 sont dépourvus de cette laque.Similar to the embodiments described above, this
packaging has sealing
