## Abstract

A cooler bag with a detachable liner and a liner base can be used as a carry bag when the liner is detached. The liner is attached to a base, which has short side walls at each end of the side of the base. The liner is folded up and placed in the base, which is then inverted to store the folded liner and serves as the base of the carry bag.
