A transport packaging structure of variable volume having four generally parallel and mutually adjacent angle-pieces. Each angle piece has two flanges which define an angle of generally 90° therebetween such as to form an inner corner which faces towards the interior of the structure. Mutually adjacent angle-pieces on at least three sides of the packaging structure are held together by at least one arm which functions to enable two angle-pieces to be spaced apart by a selective distance. |
