A simple plastic container will easily hold your food. But a stainless steel travel jar is, in lots of cases, a better option. The Zoku 10oz Neat Stack Food Jar has a vacuum insulated, double-walled design to ensure your food stays hot for 5 hours or cold for 6.5 hours. Capacity is 295ml (10oz), it's BPA and phthalate free, and has a wide diameter opening for easy access. And for travellers, several jars can be stacked to maximise your available storage space.
