Tupperware's FlatOut! storage containers were designed for the consumer who needs flexibility in storage and for busy people on the go-students, working professionals and campers. Its accordion design allows FlatOut! to be adjusted to the appropriate capacity for the food to be stored or for space-saving stackable storage. When the container is closed the seals are completely watertight. For cleaning, they can be stacked like plates into a dishwasher and washed flat. In December 2004, the product was awarded a Good Buy Award by the Good Housekeeping Institute and was named by Fortune magazine as one of the best 25 products of the year in their December 2004 issue. It was also recently awarded a "Product of the Year 2005" award by the German Consumer Plastics Institute.
