A rigid container for tobacco items, defined by a tubular lateral wall ( 11 ) and by at least one end wall ( 6 ), and wherein one of the two walls ( 6, 11 ) has at least one inwardly concave portion ( 13; 82; 91; 96; 102; 113 ), and the other wall has at least one flat portion ( 8; 114 ), which mates with the concave portion ( 13; 82; 91; 96; 102; 113 ) along a convex outer edge portion ( 10, 115 ) of its own, and is formed from a panel ( 6'; 6', 6''; 121 a , 122 a) having a first portion ( 6' a ; 6' a , 6'' a ; 128 ) corresponding to the flat portion ( 8; 114 ), and a peripheral second portion defined by at least one curved strip ( 20; 20', 20''; 127 ) bounded internally by a curved crease line ( 19; 19', 19''; 126 ) extending along the convex outer edge portion ( 10; 115 ); the strip ( 20, 20', 20''; 127 ) being folded squarely, by drawing, to define a convex border ( 23; 129 ) extending along the convex outer edge portion ( 10; 115 ), and being made integral with an inner surface of the concave portion ( 13; 82; 91; 96; 102; 113 ). |
