A device for packaging and cooking popcorn includes in the lower part an essentially rigid base, and in the upper part a compensating zone that can occupy a first folded position in which it forms a cover for the base and delimits a restricted volume, and a second unfolded position in which it forms a tube and delimits a larger volume suited to that of the cooked popcorn. The device is produced from a complex material that includes a layer made of cardboard-type material to ensure the rigidity and a layer that is made of flexible and airtight plastic that is placed on the surface oriented toward the inside of the device. The device includes a window at least at the level of a wall of the compensating zone, whereby the complex material does not have a layer that is made of cardboard-type material to the right of the window.
