The cart comprises a collapsible container extending from a top surface of a bottom shell, a handgrip disposed close to the container for steering the cart, and a plurality of wheels for rolling the cart; the wheels attached to the top shell. The cart further comprises a top shell hinged to the bottom shell such that the top shell can be closed over the bottom shell thereby forming the clamshell case; the top shell to close over the bottom shell only when the container is collapsed.
