Pizza box can be used as pizza plates

Today I would like to talk about an idea about Pizza box. Sometime you order a pizza and a couple of people would share the pizza but with no plates. I am thinking the Pizza box can be designed to be easily cut into "plate" pieces. These plates then can be used to hold the Pizza. Especially, the cap of the box can be easily designed to have 4 small plates. That will provide a lot of convenience and also save our environment for not using extra plates.
