Abstract
Packaging for foodstuffs comprising a device for automatic closure at the end of cooking. The automatic closure device (15) comprises a first chamber (38) communicating with the outside and enclosing a valve and second chamber (40) communicating with the first chamber and enclosing a block of thermofusible material, such second chamber communicating with the interior of the packaging by a channel of small cross section (41). During cooking, the gases can leave freely from the packaging and, at the onset of cooling, the valve prevents air from penetrating the packaging while the thermofusible material solidifies in the channel of small cross section.

Package for foodstuffs, adapted to receive food to be cooked at least in part in situ, said package comprising:
- an automatic closure device fixed in sealed manner through one wall (12a) of the package, said automatic closure device comprising a first chamber (38) communicating with the outside and enclosing a valve (35), a second chamber (40) communicating with said first chamber through a passage (31) adapted to be closed by said valve, a channel (41) of small cross section extending between said second chamber and the interior of the package, and a block of thermofusible material (44) disposed in said second chamber, whereby said block of thermofusible material will soften during cooking, flow into said channel and upon cooling solidify therein to provide a hermetic seal.
Wrapped foodstuff, precooked in a package, said package being hermetically closed at the end of cooking, and comprising an automatic closure device fixed sealingly through one wall (12a) of the package, the automatic closure device (15) comprising a first chamber (38) communicating with the outside and enclosing a valve (35), a second chamber (40) communicating with said first chamber through a passage (31) adapted to be closed by said valve, a channel (41) of small cross section extending between said second chamber (40) and the interior of the package and thermofusible material (44a) closing said channel.
