Existing examples of airline meals

These are some existing examples of airline meals.
it is obvious that is little order to the trays and the whole thing looks like a mess. I want to design a simple net that can be turned into a box that can hold each part of the meal and promote the campaign at the same time.
From the examples below you can see that a meal will generally consist of 1 main meal box, 2 smaller pots and a drink or two (water/juice/coffee).
