Abstract

The device has an outer package (1) isolating product contained in an inner package (2) from oxygen and humidity of an external ambient air. Condensation (4) that occurs in the form of steam during heating of the product is settled on an inner part of the outer package and does not contact the product, at the time of thermal shock. The condensation drips on an outer wall of the inner package in case of streaming. An independent claim is also included for a method to pack products such as fruits and vegetables, and cool or frozen dishes prepared with fruits or vegetables such as mixed salads.

Description

Page 1Page 1

La présente invention concerne un procédé d'emballage pour conserver les fruits et les légumes ainsi que les plats, frais ou surgelés, préparés à base de fruits ou de légumes, tels que les salades composées.  The present invention relates to a packaging method for preserving fruit and vegetables as well as dishes, fresh or frozen, prepared with fruit or vegetables, such as mixed salads.

Premièrement ces produits sont traditionnellement stockés à l'air ambiant ou bien dans des boîtes ou des sachets simples fermés, ventilés ou non, ce qui les expose à l'action des gaz, de l'humidité et du 5 froid, et occasionne ainsi une dégradation très rapide de leur qualité.  Firstly, these products are traditionally stored in ambient air or in closed single boxes or bags, ventilated or not, which exposes them to the action of gases, moisture and cold, and thus causes very rapid degradation of their quality.

Deuxièmement certaines boîtes ou sachets fermés contiennent parfois un gaz pour éviter le développement de bactéries ou de moisissures, mais lors de chocs thermiques mêmes très légers, il se produit toujours une condensation à l'intérieur de ces boîtes ou de ces sachets, ce qui favorise l'oxydation ainsi que le dégagement d'éthylène et altère la qualité des fruits et des légumes.  Secondly some closed boxes or sachets sometimes contain a gas to prevent the growth of bacteria or mold, but during even very slight thermal shocks, condensation always occurs inside these boxes or pouches, which favors oxidation as well as the release of ethylene and alters the quality of fruits and vegetables.

Les mélanges gazeux utilisés contiennent souvent de l'azote et du gaz carbonique dont la proportion est volontairement limitée, car au delà d'une certaine quantité, ce gaz nuit à la qualité des aliments car il apporte une sensation désagréable de picotement et d'acidité. Il est par ailleurs nécessaire de permettre aux fruits et aux légumes de respirer de l'oxygène, ce qui rend ce procédé de conservation partiellement inefficace.  The gaseous mixtures used often contain nitrogen and carbon dioxide, the proportion of which is voluntarily limited, because beyond a certain quantity, this gas is detrimental to the quality of the food because it brings an unpleasant sensation of stinging and acidity. . It is also necessary to allow the fruits and vegetables to breathe oxygen, which makes this preservation process partially ineffective.

Le dispositif selon l'invention permet de remédier à ces deux inconvénients.  The device according to the invention overcomes these two disadvantages.

II comporte en effet une première caractéristique, un emballage constitué d'une partie externe isolant le produit de l'oxygène et de l'humidité de l'air ambiant extérieur, et d'une partie interne évitant l'accumulation sur les fruits et les légumes, de l'humidité qu'ils libèrent, les deux emballages apportant une seconde caractéristique par un effet iso thermique qui permet la concentration de l'humidité et des gaz sous produits de respiration, en un endroit choisi dans l'emballage, avec un effet de convection.  It has indeed a first feature, a package consisting of an outer part insulating the product of oxygen and moisture from the outside ambient air, and an inner part avoiding accumulation on fruits and vegetables. vegetables, moisture they release, the two packages providing a second characteristic by an isothermal effect that allows the concentration of moisture and gases by breathing products, in a selected location in the package, with a convection effect.

Selon des modes particuliers de réalisation: - la partie externe de l'emballage est réalisée en matière transparente suffisamment épaisse et hermétique par exemple en polychlorure de vinyle, polyéthylène de téreftalate ou matériau équivalent bio dégradable ou non, dans un format adapté au produit, elle est pourvue d'une zone fragilisée et d'une languette permettant son ouverture facilement par déchirement. Sa forme peut varier suivant la forme du produit contenu 25: cylindrique, ronde, ovale, carrée, rectangulaire ou triangulaire.  According to particular embodiments: the outer part of the packaging is made of transparent material that is sufficiently thick and hermetic, for example polyvinyl chloride, polyethylene tereftalate or bio degradable equivalent material or not, in a format adapted to the product; is provided with a weakened zone and a tongue allowing its easy opening by tearing. Its shape may vary depending on the shape of the product contained 25: cylindrical, round, oval, square, rectangular or triangular.

- la partie interne de l'emballage est réalisée dans la même matière transparente, de plus fine épaisseur, et comporte des micro perforations, dans un format adapté au produit, elle est contenue dans la partie externe de l'emballage.  - The inner part of the package is made of the same transparent material, thinner, and has micro perforations in a format adapted to the product, it is contained in the outer part of the package.

- l'emballage interne est en contact direct avec le produit, - l'emballage externe contient un mélange gazeux évitant le développement de bactéries ou de moisissures dont les proportions varient suivant le produit contenu.  - the inner packaging is in direct contact with the product, - the outer packaging contains a gas mixture avoiding the development of bacteria or mold whose proportions vary depending on the product contained.

Le dessin annexé illustre l'invention: La figure 2 représente le procédé de l'invention en coupe longitudinale En référence à ce dessin, le dispositif comporte un emballage externe (1) renfermant un mélange gazeux et un emballage interne (2) contenant le produit à conserver.  The attached drawing illustrates the invention: FIG. 2 represents the method of the invention in longitudinal section With reference to this drawing, the device comprises an outer packaging (1) containing a gaseous mixture and an inner packaging (2) containing the product to conserve.

Page 2 Le produit est isolé de l'oxygène et de l'humidité contenus dans l'air extérieur ambiant, empêchant ainsi leur action sur le produit contenu dans l'emballage interne (2) L'humidité et les gaz sous produits de respiration libérés par les fruits légumes s'évaporent hors de l'emballage interne (2), se fixent jusqu'à saturation à l'extérieur de celui-ci, dans l'emballage extérieur (1). Un mélange gazeux alimentaire est injecté entre les deux emballages. Lors de choc thermique, la condensation (4) qui se produit sous forme de buée lors du réchauffement du produit se fixe sur la partie interne de l'emballage externe où elle y est contenue volontairement et n'entre plus en contact avec le produit, car en cas de ruissellement elle glisse sur la paroi externe de l'emballage interne, ce qui évite l'oxydation des fruits et des légumes, la production d'éthylène, et la dégradation.  The product is isolated from the oxygen and moisture contained in the ambient outside air, thus preventing their action on the product contained in the inner packaging. (2) Moisture and gases released by breathing products released by the vegetable fruits evaporate out of the inner packaging (2), are fixed to saturation on the outside thereof, in the outer packaging (1). A gaseous food mixture is injected between the two packages. During thermal shock, the condensation (4) which takes place in the form of steam during the heating of the product is fixed on the inner part of the outer packaging where it is contained voluntarily and no longer comes into contact with the product, because in case of runoff it slides on the outer wall of the inner packaging, which avoids the oxidation of fruits and vegetables, the production of ethylene, and degradation.

A titre d'exemple non limitatif, l'emballage externe comportera des sections carrées et l'emballage interne sera cylindrique. Leurs dimensions non limitatives seront par exemple pour un produit d'une longueur de 30 centimètres et d'un diamètre d'environ 6 centimètres, de l'ordre de: pour l'emballage externe: d'environ 30 cm dans la longueur, d'environ 8 cm dans la hauteur, 15 d'environ 8 cm dans la largeur, et d'une épaisseur de 40 microns, - pour l'emballage interne: d'une longueur d'environ 30 centimètres, d'un diamètre d'environ 6 centimètres, et d'une épaisseur de 30 microns.  By way of non-limiting example, the outer package will have square sections and the inner package will be cylindrical. Their non-limiting dimensions will for example be for a product with a length of 30 centimeters and a diameter of about 6 centimeters, of the order of: for the outer packaging: about 30 cm in length, d about 8 cm in height, about 8 cm in width, and 40 microns thick, - for inner packaging: about 30 cm long, with a diameter of about 6 centimeters, and a thickness of 30 microns.

A titre d'exemple non limitatif, le mélange gazeux sera composé de 50 % d'azote et de 45 % de gaz carbonique. La composition du gaz alimentaire est conforme aux dispositions sanitaires réglementaires.  By way of non-limiting example, the gaseous mixture will be composed of 50% nitrogen and 45% carbon dioxide. The composition of the food gas complies with the sanitary regulations.

La languette (5) disposée sur la zone fragilisée (3) de l'emballage externe (1) sert à ouvrir cet emballage.  The tongue (5) disposed on the weakened zone (3) of the outer packaging (1) serves to open this package.

L'emballage selon l'invention est particulièrement destiné au conditionnement des fruits et des légumes ainsi que les plats, frais ou surgelés, préparés à base de fruits ou de légumes, tels que les salades composées.  The packaging according to the invention is particularly intended for packaging fruit and vegetables as well as dishes, fresh or frozen, prepared with fruit or vegetables, such as mixed salads.
