Abstract

A container converting between a briefcase, a food and beverage carriage, and a mini-cooler. The container has a case which functions as a briefcase. The case includes a base and a top, each of which has walls defining a hollow center filled with insulating material. The top is secured by a hinge to the base along coextensive edges. A plurality of separate food and beverage carriage inserts may be removably positioned in the base to convert the case into a food and beverage carriage. An insulating mini-cooler adapter converts the case into a mini-cooler.
