Abstract: An extensible handle (22) spanning a top panel of a carton is being extensible from a flat stowed position in which a central hand gripping portion (26) of the handle lies substantially in the plane of the top panel to an extended position in which the hand gripping portion is raised out of the plane of the top panel. The handle includes a hinged gusset portion (40) which lies in superposed relationship with a part of the handle when the handle is in its stowed position and which is hinged out of its superposed relationship when the handle is grasped to lift the carton thereby to allow the handle to extend.
