Abstract
Abstract A knock down hamper having a body containing an elongated portion divided into four sections, two of which are enclosed frames and two of which are partially enclosed frames. The frames are covered by a continuous piece of flexible material forming the cover of the hamper and which may be folded to make the hamper fit into a relatively thin and flat shipping and display carton. The top and bottom frame pieces have tongues and grooves designed to fit together and the bottom pieces of each frame have a continuous groove to hold the bottom board of the hamper. There are hinges on one of the top frame pieces to hold the lid of the hamper which fits inside of one of the frames when inserted in the shipping and display carton.
