Abstract
Abstract A thermal container for insertion into a backpack having separate attachment means for securing an integral flap and sealing means for further sealing an opening of said insert container. The container has an open position for receiving carried items and a closed position for sealing the carried items therein. The closure flap is integrally formed with a body of the container. Closure of the flap deforms the body along deformation lines, closing and opening. Selectively positionable stops drawn tightly against the closure flap seals the opening and the items carried therein. The container is insertable into any one of a number of backpacks, and the drawstring can be used as a carrying handle.
