Abstract

The storage and sales display container for portions of food, is shaped as a flanged dish (10) with its open top sealed by a protective layer (12,14). This layer is a double layer, with an anti-condensation film (14) covered by an outer film (12) which is gastight and which may carry printed information. Before sealing, the container is filled with an inert gas preventing deformation of the container during cold storage. The double layer is then welded all round the flanges of the container. When ready for display, the gastight layer can be removed by a tongue (16) at one end. The lower layer, which is porous, allows air to reoxygenate the contents.

Description

La présente invention est relative à un procédé et à un emballage pour la conservation de produits alimentaires et elle vise plus particulièrement le conditionnement de viande fraiche en portions. The present invention relates to a method and a packaging for the preservation of food products and it relates more particularly to the packaging of fresh meat in portions.

il existe à l'heure actuelle un certain nombre de procédés permet tant de conserver des produits alimentaires sous la forme de parts ou de portions prêtes à la vente. Ces procédés peuvent être ranges en deux catégories:
1 - les procédés selon lesquels les produits à conserver sont pla cés dans un conteneur (par exemple un récipient appelé l'barquette" recouvert d'une pellicule de matière plastique etanche aux gaz, les conteneurs étant stockes au froid.Dans le cas du conditionnement de portions de viande franche, ces procédés présentent l'inconvénient selon lequel, en raison d'un défaut d'oxygène, il se produit un brunissement de la viande, ce qui ne permet pas de maintenir l'aspect rouge de la viande franche dejniandé par le consommateur.There are currently a number of methods for both preserving food products in the form of parts or portions ready for sale. These processes can be classified into two categories:
1 - the processes according to which the products to be stored are placed in a container (for example a container called the tray "covered with a film of gas-tight plastic material, the containers being stored cold. In the case of packaging portions of free meat, these methods have the disadvantage that, due to a lack of oxygen, there is browning of the meat, which does not allow to maintain the red appearance of dejniandé free meat by the consumer.

2 - Les procédés selon lesquels les produits à conserver sont places dans un récipient étanche aux gaz, recouveru d'unie pellicule étanche aux gaz, le volume entre le récipient et la pellicule étant rempli d'un mélange gaz eux oxydant. Les produits à conserver, par exemple de la viande fraiche en portions, sont conserves à une température voisine du point de congélation. 2 - The processes according to which the products to be stored are placed in a gas-tight container, covered with a gas-tight film, the volume between the container and the film being filled with an oxidizing gas mixture. The products to be stored, for example fresh meat in portions, are stored at a temperature close to the freezing point.

Ce procédé présente l'avantage de maintenir la coloration rouge franche de la viande crue. Cependant la durée de conservation ne dépasse pas une dizaine de jours, la présence d'une atmosphère oxydante autour de la viande en traitant un développement des germes.This process has the advantage of maintaining the frank red coloration of raw meat. However, the shelf life does not exceed ten days, the presence of an oxidizing atmosphere around the meat while treating the development of germs.

L'invention se propose d'apporter un procédé et un emballage pour la conservation de produits alimentaires et plus particulièrement de viande franche en portions qui offrent un allongement de la durée de conservation et une présentation à la vente dans laquelle llaspect rouge de la viande franche est restitué. The invention proposes to provide a method and a packaging for the preservation of food products and more particularly of free meat in portions which offer an extension of the shelf life and a presentation for sale in which the red aspect of the free meat is returned.

Le procédé selon la présente invention est caractérisé en ce que lton place, commue connu, le produit alimentaire à conserver dans un récipient étanche, notamment du type barquette, en ce que l'on obture ledit récipient à l'aide d'une double pellicule: une pellicule intérieure perméable aux gaz et une pellicule extérieure imperméable aux gaz, et en ce qu'on fait le vide dans le récipient ainsi fermé, un gar inerte étant ensuite injecté dans le récipient pour éviter la déformation de la barquette. The process according to the present invention is characterized in that, as known, the food product to be stored is placed in a sealed container, in particular of the tray type, in that the said container is closed with a double film. : an inner film permeable to gases and an outer film impermeable to gases, and in that a vacuum is made in the container thus closed, an inert gar is then injected into the container to avoid deformation of the tray.

Les emballages ainsi obtenus peuvent être stockés, à une température voisine de la température de congélation, pendant la durée légale pour la conservation de la viande sous vide, et avant leur mise en vente il suffit de détacher la pellicule extérieure étanche aux gaz pour permettre une réoxygénation de la viande au travers de la pellicule intérieure perméable aux gaz, ce qui redonne à la viande sa couleur rouge normale pendant la durée légale de vente sous cette forme
L'invention vise également un emballage pour produits alimentaires et notamment pour portions de viande fraiche, caractérisé en ce qulil comprend un récipient étanche aux gaz, de préférence du type barquette, obturé par une double pellicule : une pellicule extérieure détachable imperméable aux gaz et une pellicule intérieure perméable aux gaz, la pellicule extérieure étant enlevée avant la mise en vente afin d'assurer la réoxygénation du produit conditionné.The packages thus obtained can be stored, at a temperature close to the freezing temperature, during the legal period for the preservation of the meat under vacuum, and before their sale it is enough to detach the outer gas-tight film to allow a re-oxygenation of the meat through the gas-permeable inner film, which restores the meat to its normal red color during the legal period of sale in this form
The invention also relates to a packaging for food products and in particular for portions of fresh meat, characterized in that it comprises a gas-tight container, preferably of the tray type, closed by a double film: a detachable external film impermeable to gases and a gas-permeable inner film, the external film being removed before sale to ensure re-oxygenation of the packaged product.

D'autres caractéristiques et avantages de cette invention ressortiront de la description faite ci-après en référence au dessin annexé qui illustre à titre d'exemple non limitatif un emballage selon l'invention. Other characteristics and advantages of this invention will emerge from the description given below with reference to the appended drawing which illustrates by way of non-limiting example a package according to the invention.

Sur le dessin
la figure 1 est une vue en perspective d'un emballage selon l'invention, et
la figure 2 illustre l'emballage selon la figure 1 en cours de préparation pour la mise à la vente.On the drawing
FIG. 1 is a perspective view of a package according to the invention, and
Figure 2 illustrates the packaging according to Figure 1 being prepared for sale.

En se référant au dessin, on voit que l'emballage selon l'invention comprend un récipient 10, de préférence du type barquette, étanche aux gaz, par exemple en matière plastique thermoformée, dans lequel est placé le produit à conserver, par exemple une portion de viande fraiche. Referring to the drawing, it can be seen that the packaging according to the invention comprises a container 10, preferably of the tray type, gas tight, for example made of thermoformed plastic, in which is placed the product to be stored, for example a portion of fresh meat.

Ce récipient 10 est obturé par une double pellicule
- une pellicule extérieure 12 imperméable aux gaz, constituée d'un laminé pelable et de préférence imprimable, et
- une pellicule intérieure 14, perméable aux gaz, de préférence anti-buée. This container 10 is closed with a double film
an outer gas-impermeable film 12, consisting of a peelable and preferably printable laminate, and
- an inner film 14, permeable to gases, preferably anti-fog.

Ces deux pellicules superposées dans l'ordre ci-dessus sont soudées par leurs bords sur les lèvres du récipient 10 ainsi qu'on peut le voir sur le dessin. La pellicule supérieure 12 peut être détachée indépendamment de la pellicule inférieure 14 ainsi qu'on peut le voir sur la figure 2. A cet effet, elle comporte une languette de traction 16. These two films superimposed in the above order are welded by their edges to the lips of the container 10 as can be seen in the drawing. The upper film 12 can be detached independently of the lower film 14 as can be seen in FIG. 2. For this purpose, it has a pull tab 16.

Ainsi qu'on l'a indiqué plus haut, après mise sous vide on a rempli d'un gaz inerte le récipient obturé 10, afin d'éviter sa déformation. As indicated above, after placing under vacuum, the closed container 10 is filled with an inert gas, in order to avoid its deformation.

Ce récipient est utilisé de la façon suivante
I1 est stocké à une température voisine de la température de congélation, dans l'état représenté à la figure 1, c'est-à-dire obturé par la double pellicule, la pellicule supérieure 12 s'opposant au passage de l'air et assurait une conservation de longue durée du produit conditionné, notamment de la viande.This container is used as follows
I1 is stored at a temperature close to the freezing temperature, in the state shown in FIG. 1, that is to say closed by the double film, the upper film 12 opposing the passage of air and ensured a long-term preservation of the packaged product, in particular meat.

Avant l'exposition en vue de la mise en vente, on détache la pelle cule supérieure étanche 12, en utilisant-la languette 16, comme représenté à la figure 2. La pellicule inférieure 14 étant perméable aux gaz, il se produit une réoxygénation naturelle du produit conditionné. Si celui-ci est de la viande franche, cette réoxygénation lui redonne sa couleur rouge fraiche. Before the exhibition for sale, the waterproof upper shovel 12 is detached, using the tongue 16, as shown in FIG. 2. The lower film 14 being permeable to gases, natural reoxygenation takes place of the packaged product. If it is straight meat, this reoxygenation gives it its fresh red color.

Il demeure bien entendu que cette invention n'est pas limitée à l'exemple de réalisation décrit et représenté, mais qu'elle en englobe toutes les variantes.  It remains to be understood that this invention is not limited to the embodiment described and shown, but that it encompasses all variants thereof.
