Abstract
A door structure includes a door frame having edge portions of which at least some are curved. The door structure further includes a flexible door panel which is pivotable between an open configuration and a closed configuration. The door panel is resiliently deformable from a substantially flat configuration to a curved configuration which corresponds to the curvature of the curved edge portions of the door frame. In the closed configuration the door panel is adapted to adopt the curved configuration and in the open position, the door panel is freely straightenable to the substantially flat configuration. The door structure may be embodied in a storage structure which includes a framework defining an interior including a storage space and an opening to the storage space. The door panel may be hingedly connected to an auxiliary portion which is slidably mounted substantially within the interior of the framework.
