Startup Idea : Pizza delivery

I am appalled by the wastage of huge amounts of packing material in delivering pizza and other food items. It also pains me to see the stress it puts on delivery boys to drive through unpredictable busy traffic to deliver the items on time. If we could devise a kind of light weight plastic flat hot box that would have a properly moulded space to hold the pizza snugly, it would be of great use. The pizza can be transferred directly to the hot box, hot box is closed and taken out for delivery. Since item remains hot for much longer time there need not be much haste in delivery. The pizza may be transferred to the plate or to a similar customer's hot plate and the vendors hot plate is returned for re use.
