DESCRIPTION:
BRIEF SUMMARY
This invention relates to the packaging of food products, in particular ready-to-cook or ready-to-heat products, and containers specially designed for such an application.
Ready-to-cook products are usually packaged in packs formed by an aluminum foil or plastic bag. With the advent of microwave ovens, plastic packs have tended to take the place of metal packs. While such packaging is without doubt suitable for cooking or heating purposes, it lends an unsatisfactory industrial aspect to the product.
A packaging for cooked meals intended to heated exclusively in a microwave oven is also known in the state of the art. This packaging was described in German patent OS3812118. It is a dish-shaped recipient, made of chipboard and covered by an internal polyethylene or polyester coating.
However, no-one has ever considered the possibility of using wood packaging for cooking in a heating oven. Such a solution runs counter to the preconceptions of specialists who logically consider that the wood is likely to catch fire due to the heat and is therefore unsuited for use as a cooking mold.
Surprisingly, it has emerged that it is possible to cook a food product packaged in a container of folded and assembled wood in a standard baker's oven. In particular, it appears that such a packaging is suitable for the cooking of dough for bread, brioches, cakes, etc., and more generally for any food product necessitating more than 30 minutes' cooking in a heating oven at temperatures exceeding 200.degree. C. and even 250.degree. C.
This invention aims firstly to propose a packaging process which combines a traditional appearance prior to use with the possibility of forming a cooking mold for use in a heating oven. In addition, the invention proposes a packaging process which is inexpensive and which, unlike the cold-molded wooden recipients described in the German patent mentioned above, does not require heavy investment for industrial production.
For this purpose, the invention concerns a packaging process for food products to be cooked or heated in a heating oven, the process comprising depositing the food product in a container formed by a single blank of very thinly manufactured wood (i.e., peeled wood or veneer), folded and assembled through refolded lateral walls.
Advantageously, the packaging process comprises placing the food product to be cooked or heated in a container formed by folding and assembling a blank which possesses a central part forming the bottom of the container, whether or not cut out, prolonged a two opposite ends by two sides separated from the central part by pre-grooved lines, and at the other two opposite ends by sides separated from the central part by pre-grooved lines laterally prolonged by connecting tabs separated from the sides by pre-grooved lines.
According to a first variant, the lateral walls are assembled by stapling.
According to a preferred second variant, the lateral walls are assembled by gluing, using a cyanoacrylate-type glue. This kind of glue is particularly suitable for reasons which will be explained at a later stage and by virtue of its resistance to heat, unlike other industrial adhesives such as heat-fusible glues.
According to a preferred application, the food product is placed in the container, in the state of uncooked dough, to be cooked in the heating oven.
According to a variant, a sheet of greaseproof paper or a fatty substance is inserted between the container and the food product so as to prevent the dough from sticking to the container during cooking.
The invention also aims to propose containers for use in the above-mentioned packaging process.
There are numerous variants of containers made of peeled wood known in the state of the art. The best known containers are manufactured by the interlacing of narrow strips joined together by stapling. Such containers are not very attractive and are suitable for routine transport and storage purposes. The main advantage of this kind of container lies in its low cost price.
With a view to a more attractive presentation, container
