A microwavable lidded container assembly comprising a container base having peripheral walls and an open top, a lid able to seat and thereby close the container base at the open top to define an enclosure; characterised in that the lid has a closable vent and the lid has a body adapted to carry a near peripheral seal to be interposed between a downward facing shoulder or plateau of the lid onto the top of a peripheral wall of the base container yet to have outstands at opposed perimeter regions of the lid to act as handle pairs for lifting the lid relative to the container base to deseat the lid therefrom.

1. A lid, or lid body of a lid assembly, having a peripheral profile at or near its periphery, said peripheral profile adapted to seal directly, or indirectly via an interposed seal, onto an underlying compatible container, wherein points of contact between a downwardly facing edge of the peripheral profile and an upwardly facing edge of the underlying container, when the lid is sealed onto the container, define a notional closure plane; wherein at opposed edges of the lid when viewed in plan view, the lid or lid body has been moulded with an outstand, said outstand formed as a smooth continuation of an outermost peripheral portion of the lid, wherein said outstand flares upwardly and outwardly of the peripheral profile such that at least a portion of a downwardly facing surface of the outermost edge of the outstand is above the notional closure plane and concave, said outstand being adapted to allow finger engagement therewith such that a finger, when engaged with said downwardly facing surface of the outstand, engages at a position above the notional closure plane during and to assist uplifting of the lid or lid body. 2. The lid, or lid body of a lid assembly as claimed in claim 1 wherein said lid or lid body is quadrilateral in plan shape and wherein the outstands are positioned at corners of the lid or lid body. 3. The lid or lid body of a lid assembly as claimed in claim 1 wherein each outstand defines a downwardly facing lifting surface which is non planar. 4. The lid or lid body of a lid assembly as claimed in claim 1 wherein the lid or lid body carries an underlying elastomeric seal able to be held by a seal matching downwardly facing shoulder, plateau or other continuous profile to the underlying compatible container, said container being a complementary underlying walled open topped container. 5. The lid or lid body of a lid assembly as claimed in claim 1 which carries latches at opposed edges of the lid or lid body, said latches configured and adapted to engage with the container to secure the lid or lid body to the container. 6. The lid or lid body of a lid assembly as claimed in claim 1 which has a closable vent. 7. The lid or lid body of a lid assembly as claimed in claim 1 wherein the peripheral profile or, if present, the interposed seal seat with the container at the notional closure plane, and wherein the lid body is adapted and configured to allow the deseating of the lid from the container without substantial out of plane deformation of the peripheral profile. 8. The lid or lid body of a lid assembly as claimed in claim 1 wherein a lip of the lid extends about the peripheral profile and projects a distance below the peripheral profile and interposed seal, if present, to prevent any flow of fluid from the enclosure of the lidded container during deseating being directed purely outwardly in a direction substantially parallel to the notional plane of the peripheral profile. 9. A lidded container suitable for use in an operational microwave oven comprising a container base having peripheral walls and an open top,a lid able to seat and thereby close the container base at the open top to define an enclosure;wherein the lid has a body adapted to carry a near peripheral seal to be interposed between a downward facing shoulder or plateau of the lid onto the top of a peripheral wall of the base container,wherein points of contact between a downwardly facing edge of the seal and an upwardly facing edge of the peripheral wall of the base container, when the lid is sealed onto the container, define a notional closure plane,wherein the lid has outstands moulded as a smooth continuation of an outermost peripheral portion of the lid at opposed perimeter regions of the lid to act as handle pairs for lifting the lid relative to the container base to deseat the lid therefrom, said outstands being of a shape that flares upwardly and outwardly of the peripheral seal such that at least a portion of a downwardly facing surface of the outermost free edge of the outstand is above the notional closure plane and concave, said outstands being adapted to allow finger engagement therewith such that a finger, when engaged with said downwardly facing surface of the outstand, engages at a position above the notional closure plane during lifting of the lid. 10. The lidded container as claimed in claim 9 wherein said lid and said container are quadrilateral in plan shape and wherein the outstands are positioned at corners of the lid. 11. The lidded container as claimed in claim 9 wherein each outstand defines a downwardly facing lifting surface which is non planar. 12. The lidded container as claimed in claim 9 wherein the outstands are handles integrally moulded with said body. 13. The lidded container as claimed in claim 12 wherein the lid has a closable vent. 14. The lidded container as claimed in claim 12 wherein said container base is of a substantially quadrilateral footprint and has a peripheral wall with at least one of: i) outwardly bulging wall regions andii) convexly curved transitions between wall regions. 15. The lidded container as claimed in claim 9 wherein the lid carries an underlying elastomeric seal able to be held by a seal matching downwardly facing shoulder, plateau or other continuous profile to the underlying compatible container, said container being a complementary underlying walled open topped container. 16. The lidded container as claimed in claim 9 wherein the lid carries latches at opposed edges, said latches configured and adapted to engage with the container to secure the lid or lid body to the container. 17. The lidded container as claimed in claim 9 wherein the peripheral seal and the container base seat with each other at the notional closure plane and the lid body is adapted and configured to allow deseating to occur without substantial out of plane deformation of the peripheral seal. 18. The lidded container as claimed in claim 9 wherein the lid body and the container base are adapted and configured to allow, during the deseating of the seal, a complete peripheral gap to be created between said lid and container base, substantially simultaneously, in order to rapidly equalize pressure within the lidded container with ambient conditions. 19. The lidded container as claimed in claim 9 wherein the lid body and the container base are adapted and configured to allow, during the deseating of the seal, a complete peripheral gap to be created between said lid and container base in order to equalize pressure within the lidded container with ambient conditions in a manner evenly distributed at the complete peripheral gap. 20. The lidded container as claimed in claim 9 wherein a lip of the lid extends about the peripheral seal and projects a distance below the peripheral seal to prevent any flow of fluid from the enclosure of the lidded container during deseating being directed purely outwardly in a direction substantially parallel to the notional plane of the peripheral seal.
