A container comprising an inner thermoformed vessel (1) and an outer thermoformed vessel (2), arranged the one within the other. The side walls (9) of the outer forming (2) surround the side walls (10) of the inner forming (1). The outer side walls has inwardly projecting ribs (11), which abut the inner side walls (10) to maintain an air gap (12) between the formings, with the formings being centered with respect to each other. The air gap is present between the bases (13, 14) of the inner and outer formings, with the outer forming being provided with ribs in its base also. In use food in the container can be heated in a micro-wave oven until hot. The air gap separates a handler's fingers from direct thermal contact with the hot food so that the container remains comfortable to handle.

A container as claimed in claim 15, wherein the first vessel is provided with an integral lid connected to the rim of the vessel by a living hinge. 18. A container as claimed in claim 17, wherein the lid is shaped at its edge to cooperate with the rim of the vessel so that the lid remains closed. 19. A container as claimed in claim 15, wherein a lid is provided on the second vessel. 20. A container as claimed in claim 15, wherein the vessels are of polypropylene material, the first vessel of a translucent grade and the second vessel of a coloured grade. 21. A container as claimed in claim 15, wherein the side walls of the first and second vessels are angled such that they converge at their rims, maintaining an air gap between the two vessels. 22. A container as claimed in claim 15, wherein the first vessel includes one or more dividers such that more than one foodstuff can be heated in the same container without contamination. 23. A container as claimed in claim 22, wherein the divider(s) and lid have complementary formations for inter-engagement. 24. A plastics material food packaging container comprising: a first plastics material vessel; a second vessel arranged with its side wall(s) surrounding the side wall(s) of the first vessel; projecting ribs on the first vessel projecting outwardly and projecting ribs on the second vessel projecting inwardly, whereby heat from contents of the container, i.e. within the inner, first vessel, does not directly heat the entire wall(s) of the outer, second vessel; characterised in that rims on the first and second vessels, the rims having complementary formations for inter-engagement thereof; and the vessels being secured together by ultrasonic welding. 25. A container as claimed in claim 24, wherein both vessels are thermoformings. 26. A container as claimed in claim 24, wherein the first vessel is provided with an integral lid connected to the rim of the vessel by a living hinge. 27. A container as claimed in claim 26, wherein the lid is shaped at its edge to cooperate with the rim of the vessel so that the lid remains closed. 28. A container as claimed in claim 24, wherein a lid is provided on the second vessel. 29. A container as claimed in claim 24, wherein the vessels are of polypropylene material, the first vessel of a translucent grade and the second vessel of a coloured grade. 30. A container as claimed in claim 24, wherein the side walls of the first and second vessels are angled such that they converge at their rims, maintaining an air gap between the two vessels. 31. A container as claimed in claim 24, wherein the first vessel includes one or more dividers such that more than one foodstuff can be heated in the same container without contamination. 32. A container as claimed in claim 31, wherein the divider(s) and lid have complementary formations for inter-engagement.
