<p>A transport packaging structure of variable volume comprises four generally parallel and mutually adjacent angle-pieces (1, 2, 3, 4). Each angle piece has two flanges (11, 12) 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 (6) which functions to enable two angle-pieces to be spaced apart by a selective distance.</p> |
