Abstract:
A transport packaging structure of variable volume comprising four generally parallel and mutually adjacent angle-pieces, each having two flanges which define an angle of generally 90.degree. therebetween such as to form an inner corner which faces towards the interior of said structure, wherein pairs of mutually adjacent angle-pieces on at least three sides of the packaging structure, each pair defining one side, are respectively held together by at least one arm which functions to enable the respective pair of adjacent angle-pieces to be spaced apart at any selective distance ranging between and including a fully extended position and a fully contracted position therebetween, each arm having at least two arm links that are connected to one another at one end by a pivoting hinge and pivotally connected at a second end to a respective angle-piece such that said structure can be expanded and contracted in two mutually perpendicular directions, and further comprising a locking element separate from said arms for locking the angle-pieces in any mutually adjusted position defining said selective distance.
