Collapsible container
You want a container and you don't want a container. These adjustable containers from Tupperware collapse and flatten to about 1 inch, then expand to keep foods fresh at home or on the go. The 3-cup containers adjust to a 2 1/4 or 1 1/4-cup container for smaller capacities. The FlatOut containers can be filled with a variety of foods.
