Abstract

The invention relates to a package for containing a plurality of products for heating, comprising: a container, manufactured from a material for once-only use, provided with at least two compartments shielded from the environment, and at least one passage opening arranged in the package for a medium for reducing an overpressure in the package, wherein the pressure in the compartments can be maintained at different levels. The invention further relates to a method for heating a plurality of products for heating placed in a single container to different temperatures using a heating source.

Claims

1-15. -15. (canceled)

16. :

A package for containing a plurality of products for heating, in particular food products, comprising;

a container, manufactured from a material for once-only use, provided with at least two compartments shielded from the environment wherein the compartments are separated medium-tightly from each other, and

the individual compartments are provided with passage openings for a medium for reducing overpressure in the package, wherein the passage openings of the individual compartments differ from each other such that overpressure in individual compartments is maximized at different pressure levels.

17. :

The package as claimed in claim 16, wherein the compartments are shielded from the environment by making use of a material layer.

18. :

The package as claimed in claim 16, wherein the passage openings are blocked prior to use of the package, and open under the influence of pressure in the compartments.

19. :

The package as claimed in claim 16, wherein the passage openings are blocked prior to use of the package, and open under the influence of a determined temperature being exceeded.

20. :

The package as claimed in claim 16, wherein the separate passage openings are provided with pressure valves acting at different pressure levels.

21. :

The package as claimed in claim 16, wherein the individual compartments have passage openings with a total passage surface varying per compartment.

22. :

The package as claimed in claim 16, wherein the passage openings are blocked prior to use of the package by means of a cover element fixed with an adhesive layer, wherein the adhesive layer softens at a determined temperature.

23. :

The package as claimed in claim 22, wherein a single cover element covers a plurality of passage openings and that weakened portions are arranged in the cover element at the position of the passage openings.

24. :

The package as claimed in claim 16, wherein the passage openings are arranged in the material layer with which the compartments are shielded from the environment.

25. :

The package as claimed in claim 16, wherein the passage openings are arranged in the container.

26. :

An assembly of a package as claimed in claim 16 and a plurality of products, in particular food products, placed in the individual compartments.

27. :

A method for heating to different temperatures with a heating source a plurality of products for heating, in particular food products, placed in a single container, by heating with a heating source the container with a plurality of separated compartments provided with the products for heating, wherein an overpressure is created in the compartments which is bounded by passage openings connecting onto the individual compartments,

wherein different passage openings of the individual compartments maximize the pressure in different compartments at different pressures thus occurring different temperatures in the compartments.

28. :

The method as claimed in claim 27, wherein the container is heated with a single heating source.

29. :

The method as claimed in claim 27, wherein the container is placed in an oven.

30. :

The method as claimed in claim 27, wherein after heating the compartments are made accessible for a meal by detaching a material layer.
