Expandable insulated food container

A container assembly, comprising:

• an insulated container having an upper opening, an outer surface, an inner surface, an upper end, a lower end, and an interior space, wherein the container is formed from one or more flexible panels and comprises at least a top panel, a bottom panel, and one or more side panels, wherein the bottom panel and side panels are attached in order to form the interior space, and wherein the top panel is hingedly connected to at least one of the side panels at an upper end of the container and is reversibly securable to the remaining panels in order to close the container;
• and
• an insert having an upper opening, an outer surface, an inner surface, an upper end, a lower end, and an interior space, wherein the insert comprises:
• an upper rigid container portion having an upper end and a lower end and comprising one or more rigid side panels;
• a lower rigid container portion having an upper end and a lower end and comprising one or more rigid side panels and a rigid bottom panel, wherein the bottom panel is attached to the lower ends of the one or more rigid side panels;
• and
• a circumferential flexible panel having an upper end and a lower end, wherein the lower end of the panel is attached to the upper end of the lower rigid container portion and the upper end of the panel is attached to the lower end of the upper rigid container portion,
• wherein the insert is configured to be placed through the upper opening and contained within the interior space of the insulated container,
• wherein, in a first configuration of the insert, the lower ends of the panels of the upper rigid container portion are below the upper ends of the panels of lower rigid container portion, and
• wherein, in a second configuration of the insert, the lower ends of the panels of the upper rigid container portion are above the upper ends of the panels of lower rigid container portion, wherein the interior space of the insert in the second configuration is greater in volume than the interior space of the insert in the first configuration.
