Abstract

Outer packaging (1) is provided with a weakened zone (3) and a tongue which enables it to be easily opened by tearing. There is an inner packaging (2). Oxygen and ambient humidity are stopped and the humidity of the product ingredients contained in the inner packaging is concentrated between the two packages in a space containing a food gas. In the event of thermal shock the condensation (4) produced is fixed on the inner part of the outer packaging and does not contact the product in the inner packaging.

Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

La présente invention concerne un procedé d'emballage pour conserver le pain frais croustillant, ainsi que les produits finis fabriqués à partir de pain frais croustillant. The present invention relates to a packaging process for storing crisp fresh bread, as well as finished products made from crisp fresh bread.

Premièrement ces produits sont traditionnellement stockés à l'air ambiant ou bien dans des sachets simples aerés ce qui les expose à l'action de l'oxygène et de l'humidité et occasionne ainsi une degradation très rapide de leur qualité.  Firstly, these products are traditionally stored in ambient air or in simple aerated sachets which exposes them to the action of oxygen and humidity and thus causes very rapid degradation of their quality.

Deuxièmement certains sachets fermés contiennent parfois un gaz pour eviter le developpement de bacteries, mais lors de chocs thermiques mêmes très legers, il se produit toujours une condensation à l'interieur de ces sachets, surtout dans le cas de sandwiche chaud comme le panini, ce qui ramollit desagreablement la croûte du pain frais croustillant.  Secondly, some closed sachets sometimes contain a gas to avoid the development of bacteria, but during thermal shocks, even very slight, there is always a condensation inside these sachets, especially in the case of hot sandwiches such as panini, which unpleasantly softens the crust of crisp fresh bread.

Les melanges gazeux utilisés pour ces sachets 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 desagréable de picotement et d'acidité aux ingrediens comme les viandes, sauces, et legumes des sandwiches, ce qui rend ce procedé de conservation partiellement inefficace.  The gas mixtures used for these sachets often contain nitrogen and carbon dioxide, the proportion of which is voluntarily limited, because above a certain quantity, this gas harms the quality of the food because it brings an unpleasant tingling sensation and acidity to the ingredients such as meats, sauces, and vegetables in sandwiches, which makes this preservation process partially ineffective.

Le dispositif selon l'invention permet de remedier à ces deux inconvenients.  The device according to the invention makes it possible to remedy these two drawbacks.

Il comporte en effet une première caracteristique, un emballage constitué d'une partie externe permettant d'isoler le produit de l'oxygène et de l'humidité de l'air ambiant exterieur, et d'une partie interne permettant d'eviter l'accumulation sur la croûte du pain de l'humidité liberée par les ingrediens du produit contenu, les deux emballages apportant une seconde caracteristique par un effet isothermique qui permet la concentration de l'humidité en un endroit choisi dans l'emballage.  It has in fact a first characteristic, a packaging consisting of an external part making it possible to isolate the product from oxygen and humidity from the outside ambient air, and of an internal part making it possible to avoid the accumulation on the crust of the bread of the moisture released by the ingredients of the product, the two packages providing a second characteristic by an isothermal effect which allows the concentration of moisture in a chosen location in the package.

Selon des modes particuliers de réalisation : - la partie externe de l'emballage est réalisée en matière plastique transparente suffisamment epaisse et hermetique par exemple en polychlorure de vinyle, polyethylène de trefalate ou materiau equivalent, dans un format adapté au produit, elle est pourvue d'une zone fragilisée ainsi que d'une languette permettant son ouverture facilement par dechirement. Sa forme peut varier suivant l'utilisation du produit : cylindrique pour le stockage en distributeur automatique, ou a section carrée pour un stockage dans des cartons ou etagères.  According to particular embodiments: - the external part of the packaging is made of sufficiently thick and hermetic transparent plastic, for example polyvinyl chloride, polyethylene of trefalate or equivalent material, in a format suitable for the product, it is provided with 'a weakened area as well as a tab allowing its opening easily by tearing. Its shape can vary depending on the use of the product: cylindrical for storage in vending machines, or with square section for storage in cartons or shelves.

- la partie interne de l'emballage est réalisée de la même matière plastique transparente plus

fine et comporte des microperforations, dans un format adapté au produit, - l'emballage interne est en contact direct avec le produit, - l'emballage externe contient un melange gazeux evitant le developpement de bacteries dont les proportions varient suivant le produit contenu. - the internal part of the packaging is made of the same transparent plastic material plus

fine and contains microperforations, in a format adapted to the product, - the internal packaging is in direct contact with the product, - the external packaging contains a gas mixture preventing the development of bacteria whose proportions vary according to the product contained.

Les dessins annexés illustrent l'invention : La figure 1 represente le procedé de l'invention, La figure 2 represente le procedé de l'invention en coupe longitudinale.  The accompanying drawings illustrate the invention: Figure 1 shows the process of the invention, Figure 2 shows the process of the invention in longitudinal section.

En reference à ces dessins, le dispositif comporte un emballage externe (1) renfermant un melange gazeux et un emballage interne (2) contenant le produit à conserver.  With reference to these drawings, the device comprises an external packaging (1) containing a gas mixture and an internal packaging (2) containing the product to be preserved.

<Desc/Clms Page number 2><Desc / Clms Page number 2>

Le produit est isolé de l'oxygène et de l'humidité contenus dans l'air exterieur ambiant, empêchant ainsi leur action sur le produit contenu dans l'emballage interne (2)
L'humidité liberée par les ingrediens du pain ou du produit fini fabriqué à partir de pain frais, s'evapore hors de l'emballage interne (2) et se fixe jusqu'à saturation à l'exterieur de celui-ci, dans l'emballage exterieur (1). Un melange gazeux alimentaire est injecté entre les deux emballages. Lors de choc thermique, la condensation (4) qui se produit sous forme de buée lors du rechauffement 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 evite le ramollissement de la croûte du pain. The product is isolated from the oxygen and humidity contained in the outside ambient air, thus preventing their action on the product contained in the internal packaging (2)
The moisture liberated by the bread or finished product manufacturers made from fresh bread, evaporates out of the internal packaging (2) and settles until saturation outside of it, in the 'outer packaging (1). A food gas mixture is injected between the two packages. During thermal shock, the condensation (4) which occurs in the form of mist when the product heats up is fixed on the internal part of the external packaging where it is voluntarily contained therein and no longer comes into contact with the product, because in case of runoff it slides on the external wall of the internal packaging which avoids the softening of the crust of the bread.

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 d'environ 30 centimètres et d'un diametre d'environ 6 centimètres, de l'ordre de : - pour l'emballage externe : d'environ 30 cm dans la longueur, de 8 cm dans la hauteur, de 8 cm dans la largeur et d'une epaisseur de 30 microns, - pour l'emballage interne d'environ 30 cm dans la longueur, d'environ 6 cm de diamètre et d'une epaisseur de 20 microns.  By way of nonlimiting example, the external packaging will include square sections and the internal packaging will be cylindrical. Their non-limiting dimensions will, for example, be for a product with a length of approximately 30 centimeters and a diameter of approximately 6 centimeters, of the order of: - for the outer packaging: of approximately 30 cm in the length, 8 cm in height, 8 cm in width and 30 microns thick, - for internal packaging of approximately 30 cm in length, approximately 6 cm in diameter and a thickness of 20 microns.

A titre d'exemple non limitatif, le melange gazeux sera composé de 75 % d'azote et de 25 % de gaz carbonique.  By way of nonlimiting example, the gas mixture will be composed of 75% nitrogen and 25% carbon dioxide.

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

L'emballage selon l'invention est particulièrement destiné au conditionnement du pain frais croustillant et des sandwiches froids ou chauds fabriqués à partir de pain frais croustillant. The packaging according to the invention is particularly intended for the packaging of crisp fresh bread and cold or hot sandwiches made from crisp fresh bread.
