1. Packaging for foodstuffs to be offered for sale, comprising:
- an integral receptacle having on its top side a mouth opening and on its underside a bottom with an upright body connecting thereto and having at least one flat body part;
which mouth opening is bounded by a mouth rim which lies substantially in a flat plane and which, after filling of the receptacle with foodstuff and optionally a chosen gas or gas mixture, can co-act in hermetically sealing manner with a lid, for instance a foil connected by sealing to the mouth rim;
a generally flat displaceable part which forms part of the bottom, the body part or the lid and acts as displacer, which part is connected to the remaining peripheral part of respectively the bottom, the body part or the lid by an at least one-dimensionally elastically deformable coupling edge; and
optionally a filling with a gas serving as protective atmosphere, for instance a mixture of CO2 and N2 or CO2 and O2;
characterized in that the displaceable part has a generally rectangular shape corresponding with the shape of said remaining part of the bottom, the body or the lid;
the surface area of the displaceable part amounts to at least 50% of the total surface area of the bottom, the body or the lid;
the displaceable part substantially has bending stiffness;
an elastically deformable zone is situated in each of the four corner zones of the coupling edge and over the whole periphery of the displaceable part;
this such that the displaceable part is movable between a first position displaced to the outside and a second position displaced to the inside.

Abstract
The invention relates to a packaging for foodstuffs, comprising: a receptacle (10) having a displaceable part (16) which forms part of the bottom, the body part or the lid, which part is connected to the remaining peripheral part (16) of respectively the bottom, the body part or the lid by an elastically deformable coupling edge (17), such that the displaceable part is movable between a first position displaced to the outside and a second position displaced to the inside. The packaging has the feature that the displaceable part has a generally rectangular shape corresponding with the shape of said remaining part of the bottom, the body or the lid; the surface area of the displaceable part amounts to at least 50% of the total surface area of the bottom, the body or the lid; the displaceable part has bending stiffness.
