Definitions

• the present invention concerns a container for containing food during its conservation, refrigeration, freezing or cooking, especially applicable to microwave oven cooking by the papillote technique.
• the technique of cooking food to the papillote consists of wrapping the food to be cooked in a piece of paper forming with it a wrapper closed by several folds and folds, and putting the wrapper in an oven at a temperature and by a adequate time for cooking food, which is done with the cooperation of the vapors released by the food enclosed in the wrapper. Once the cooking is finished, the wrapper is taken out of the oven and opened or torn to extract the food, and the paper is discarded.
• this technique is traditionally carried out in a conventional convection oven, since the appearance of microwave ovens the cooking to the papillote has become popular because of the greater comfort that the use of this type of ovens represents.
• the paper used can not be any paper, but a special paper substantially impermeable to liquids and vapors, suitable for food applications and resistant to temperatures up to 200 0 C, or more, which is sold in specialized establishments.
• a drawback of this special disposable paper is that it is economically expensive and not always available in a domestic kitchen.
• special paper is customary to use aluminum foil instead, although it has several drawbacks.
• the foil is very prone to tearing and, for example, any edge, spine or similar present in the food to be cooked can destroy the wrapper and cause the spillage of the juices or even that of the food itself.
• aluminum foil is not suitable for microwave ovens due to its metallic nature.
• plastic or elastomeric containers on the market provided with a separable lid, which can be used to cook food using the papillote technique.
• Some of these containers are made of platinum catalyzed silicone and can be used in both conventional convection ovens and microwave ovens.
• these containers of the prior art are little or nothing adapted to the specific conditions of cooking in the convection oven or microwave.
• the containers generally have a flat bottom wall in contact with the support surface, which prevents hot air or microwaves from entering the outside surface of the bottom wall of the container inside the oven, which it can lengthen the time necessary for cooking the food and / or it can cause irregular cooking thereof.
• the walls of the containers of this type need to have a considerable thickness to provide a sufficient consistency for the handling of the container, and since the silicone is a poorly conductive material of heat, the thickness of The walls also have a negative effect on cooking time.
• the present invention contributes to overcoming the above and other inconveniences by providing a utensil for containing food applicable to microwave oven cooking, of the type comprising a receptacle of an elastomeric material for containing food, with an access opening and cover means for covering said access opening.
• the utensil of the present invention is characterized in that the receptacle is formed by one or more walls including a closed bottom wall and opening edges defining the access opening at a height greater than said bottom wall.
• a plurality of reinforcing ribs are formed that protrude outwardly from at least one outer surface of said bottom wall and provide a plurality of supports that substantially expose all or a major part of the outer surface of the bottom wall to The surrounding atmosphere when the receptacle is on a support surface.
• This greater thinness of the walls of the receptacle increases the capacity of heat transmission through them and decreases the time required for cooking.
• the supports provided by the reinforcing ribs allow the combed bottom wall to be separated from the support surface and therefore exposed to hot air or microwaves inside the oven, which entails faster and more uniform cooking of the food contained in the receptacle.
• the bottom wall of the utensil of the present invention has an elongated channel shape defining lateral edges of the access opening and is connected at its ends to end walls that define respective end edges of the access opening
• These final edges of the access opening of the receptacle are curved-convex and have lower ends at the level of said lateral edges and central areas that rise at a level higher than the lateral edges.
• Said cover means may comprise a single curved lid or two curved covers that have lateral edges adjacent to the lateral edges of the access opening of the receptacle and curved concave end edges resting on the final edges of the access opening of the receptacle in a closed position.
• the receptacle and the lid or the lids form in said closed position an elongated hollow body of substantially elliptical cross-section.
• the cover or the covers are also made of an elastomeric material and form a single piece body with the receptacle.
• the reinforcement ribs of the receptacle are arranged spaced apart from each other and parallel to the end walls.
• the cover or each of the covers can also have a plurality of reinforcement ribs spaced apart and parallel to the end walls of the receptacle, so that the thickness of the cover or of the covers between the ribs can also be significantly thin, for example 0.5 mm to 0.9 mm thick when platinum catalyzed silicone is used as an elastomeric material.
