A collapsible container includes an outer cup, an inner cup located inside the outer cup, and a seal covering the container. The inner cup includes a base and a plurality of concentric sections that are configured to collapse toward an opening in the container, when a force is exerted toward the opening on the base. The plurality of concentric sections may include three concentric sections: a base section, a middle section, and a top section, wherein the base section perimeter is smaller than the middle section perimeter, and the middle section perimeter is smaller than the top section perimeter.
