A rigid type wrapper ( 1 ) with a hinged lid ( 13 ) is fashioned from a flat diecut blank ( 42 ) presenting a treated face and an untreated face and comprising a main portion ( 45 ) destined to form the container ( 11 ) and the lid ( 13 ) of the wrapper ( 1 ), also an appendage ( 50 ), destined to provide a stiffening frame ( 23 ), appearing as a first portion ( 51 ) and two connecting arms ( 52 ) terminating at the opposite ends in first and second precreased fold lines ( 53, 54 ) along which the arms ( 52 ) are hinged respectively to the main portion ( 45 ) and to the first portion ( 51 ) of the blank. The frame ( 23 ) is erected by rotating the arms ( 52 ) about the respective first precreased fold line ( 53 ) to the point at which they are bent double over the main portion ( 45 ), and simultaneously rotating the first portion ( 51 ) of the appendage ( 50 ) about the respective second precreased fold lines ( 54 ) to the point at which the treated face of the first portion ( 51 ) is bent double over the untreated face of the main portion ( 45 ), so that when the wrapper ( 1 ) is fully assembled, the frame ( 23 ) will be positioned with the treated surface facing outwards.
