Abstract
A collapsible storage device comprising a resilient frame and sheet material with respect to which the frame is located. The resilient frame and sheet material form the side walls of the device and are movable between a flattened condition and an erected condition to which the resilient frame is biased. At one end of the device there is provided a base and at the other end there is provided an opening. The opening has a single closure element which has a first part attached to one side of the opening and a leading edge which can be moved about a pivotal point between a position at the said one side of the opening so that the storage device is open and a position at or in contact with the other side of the opening to close the opening. The closure element is movable with the storage device between flattened and erected conditions.
