Secure package for food products and oven intended to accommodate such a package

Abstract

A package for food products. The package has an internal volume delimited by a bottom wall, a top wall and a peripheral border. The top wall has a pre-cut to form a peripheral portion and a central portion. The central portion is extended by a cap. The peripheral border has at least one notch forming a passage for a foolproof member during insertion of the package into a heating device.

What is claimed is: 
     
         1 . A package for a food product, the package comprising:
 an internal volume delimited by:
 a bottom wall; 
 a top wall; and 
 a peripheral border connecting the bottom wall and the top wall, and having an insertion edge allowing introduction of a food product into the internal volume, 
   wherein the top wall has a pre-cut to form a peripheral portion and a central portion pivotable about a hinge relative to the peripheral portion between:
 a closed position in which the central portion and the peripheral portion are coplanar, and 
 an open position in which the central portion is pivoted relative to the peripheral portion, 
   wherein the insertion edge incorporates a first flap and a second flap extending respectively from the bottom wall and the top wall, the first flap being cooperable with the second flap to close the insertion edge,   wherein the central portion is extended by a cap which extends beyond the peripheral border in the closed position of the central portion,   and wherein the first flap has:
 a free edge forming a push-in stop into the internal volume of the central portion in the closed position, and 
 at least one notch opening onto the free edge and forming a passage for a fool-proof member during insertion of the package into a heating device in the open position of the central portion. 
   
     
     
         2 . The package according to  claim 1 , wherein the second flap has at least one lumen located at a junction between the second flap and the top wall, the at least one lumen facing the at least one notch of the first flap when the first flap cooperates with the second flap to close the insertion edge. 
     
     
         3 . The package according to  claim 1 , wherein the at least one notch of the first flap comprises two notches opening onto the free edge. 
     
     
         4 . The package according to  claim 2 , wherein the at least one lumen of the second flap comprises two lumens each of the two lumens facing a respective a notch of the at least one notch of the first flap when the first flap cooperates with the second flap to close the insertion edge. 
     
     
         5 . The package according to  claim 1 , wherein the bottom wall has an opening to be sealed by a metal dish containing a food product. 
     
     
         6 . An apparatus comprising:
 a package for containing a food product, the package comprising:
 an internal volume delimited by:
 a bottom wall; 
 a top wall; and 
 a peripheral border connecting the bottom wall and the top wall, and having an insertion edge allowing introduction of a food product into the internal volume, 
 
 wherein the top wall has a pre-cut to form a peripheral portion and a central portion pivotable about a hinge relative to the peripheral portion between:
 a closed position in which the central portion and the peripheral portion are coplanar, and 
 an open position in which the central portion is pivoted relative to the peripheral portion, 
 
 wherein the insertion edge incorporates a first flap and a second flap extending respectively from the bottom wall and the top wall, the first flap being cooperable with the second flap to close the insertion edge, 
 wherein the central portion is extended by a cap which extends beyond the peripheral border in the closed position of the central portion, 
 and wherein the first flap has:
 a free edge forming a push-in stop into the internal volume of the central portion in the closed position, and 
 at least one notch opening onto the free edge and forming a passage for a fool-proof member during insertion of the package into an oven in the open position of the central portion; and 
 
   the oven for heating a food product contained in the package, the oven comprising:
 a heating volume delimited between a lower partition, an upper partition and a peripheral partition connecting the upper partition and the lower partition, the peripheral partition being provided with a slot for inserting the package into the heating volume; 
 a support to support the package, located in the heating volume between the upper partition and the lower partition; and 
 at least one fool-proof device located in a central portion of the heating volume spaced from the insertion slot, the fool-proof device extending from the upper partition towards the support.
