PROBLEM TO BE SOLVED: To divide the interior of a packaging into two separate chambers, a lower chamber and an upper chamber, such that two different components of a product are heated and brought into contact at the time of consumption.SOLUTION: A packaging 10 in flexible material comprises a supporting base 11 from which two opposite side walls 12 rise up, each one being sealed to a half-perimeter 13 of the base 11 and sealed one to the other along respective side edges 14 and along the upper edge with a head sealing 16. In an intermediate area of the packaging 10 at least one continuous transverse sealing 17 is provided, for dividing the interior of the packaging 10 into two separate chambers, a lower chamber 20 and an upper chamber 21, so as to contain two different components of a product to be heated and brought into contact at the time of consumption. The transverse sealing 17 opens when a certain pressure is reached in the lower chamber 20, thus forming a single chamber inside the packaging 10. |
