Fast food containers have a short lifespan, but if they can be designed to be as useful as possible within that time, it's all the better.
This concept for a new McDonald's Big Mac box comes from Rob Bye, an industrial design student. Bye's design eliminates the need for a paper bag to contain all of the items ordered in a combo.
The revised Big Mac box combines fries and burgers in a single box. When the box is opened up, its top and bottom make two separate spots to hold one's burger and fries. Since a big drink is often part of McDonald's combo meals, Bye has made modifications to the Big Mac box so that it can hold a drink with ease. This still might tie up your hands if you want to grab a combo and go, but for patrons who are grabbing a tray and staying at McDonald's to eat, it's a pretty great way to get rid of greasy brown paper bags entirely.
