Pouch for steaming vegetables

1. A flexible pouch for cooking a food item using microwave energy, the pouch comprising:

a base configured to retain hot gases above atmospheric pressure within the pouch to heat and cook the food item when the package is exposed to microwave energy;

a cover comprising

a sealant layer adapted to form a permeable membrane when pressure within the pouch exceeds a first predetermined pressure, and

a score layer, wherein the score layer includes a weak portion which ruptures and vents the pouch at a predictable location when pressure within the pouch due to the hot gasses exceeds a second predetermined pressure.

2. The pouch of claim 1 , wherein the weak portion is mechanically formed in the score layer.

3. The pouch of claim 1 , wherein the weak portion is laser scored in the score layer.

4. The pouch of claim 1 , wherein the base is configured to retain said liquid within the pouch upon heating.

5. The pouch of claim 1 , wherein the pouch further comprises a plurality of handles to facilitate opening of the pouch.

6. The pouch of claim 1 , wherein the tensile strength of the score layer is greater than the tensile strength of the sealant layer.

7. The pouch of claim 6 , wherein the score layer is fastened to the sealant layer with adhesive.

8. The pouch of claim 1 , further comprising a plurality of pieces of frozen food.

9. The pouch of claim 8 , wherein the food is selected from the group consisting of individually frozen predominately carbohydrate ingredients, individually frozen predominately vegetable ingredients, individually frozen predominately meat based ingredients and combinations thereof.

10. The pouch of claim 8 , wherein the plurality of pieces of frozen food further comprises a frozen liquid.

11. A pouch meal comprising:

a plurality of pieces of frozen food;

a flexible pouch having an inner surface containing the food and an outer surface, wherein the inner surface is defined by:

a base configured to retain hot gasses above atmospheric pressure within the pouch to heat and cook the food when the pouch is exposed to microwave energy, and

a sealant layer adapted to form a permeable membrane when pressure within the pouch exceeds a first predetermined pressure; and

a score layer disposed over the sealant layer, the score layer having a weak portion configured to rupture and vent the pouch at a predictable location when the pressure within the interior of the pouch due to hot gasses exceeds a second predetermined pressure.

12. The meal of claim 11 , wherein the weak portion is laser scored in the score layer.

13. The meal of claim 11 , wherein the weak portion is mechanically formed in the score layer.

14. The meal of claim 13 , wherein the tensile strength of the score layer at a location adjacent to the score is greater than the tensile strength of the sealant layer.

15. The meal of claim 14 , wherein the tensile strength of the score layer at the weak portion is greater than the tensile strength of the sealant layer.

16. The meal of claim 15 , wherein the score layer is fastened to the sealant layer.

17. The meal of claim 16 , wherein the food is selected from the group consisting of individually frozen predominately carbohydrate ingredients, individually frozen predominately vegetable ingredients, individually frozen predominately meat based ingredients, and combinations thereof.

18. The meal of claim 17 , wherein the base is configured to retain said liquid within the pouch upon heating.

19. The meal of claim 18 , wherein the pouch further comprises a plurality of handles to facilitate opening of the pouch.
