Abstract: A thermal insulated delivery bag is configured for use with both hot and cold food delivery. The bag converts shape from a horizontal configuration to a vertical (tote) configuration which may optimize use depending on the type of food to be transported. For example, the horizontal configuration may accommodate large flat items while the vertical configuration may accommodate other items, which may be divided into separate internal sections by a divider. The bag includes a divider system to accommodate change in the size of two or more separate internal sections (e.g., segregating cold and hot items). The divider system enables movement/repositioning to change the size of the internal sections while maintaining a substantial thermal isolation of each internal section. In some embodiments, the divider may be held in a position/orientation by coupling of magnets to one or more ferrous strips in the bag.
