After spending the week playing around with paper prototypes and cardboard models I recieved the following feedback:
Max Glanville
Suggested that my lid should punch the foil base once lifted off the container.
He also suggested that I add finger grooves to the circular lid for better grip.
Matthew Patane:
Suggested I add a flat side and a curved side so the consumer knows which way is up.
He also mentioned that my design needs to be price realistic and I should look to other materials.
