Abstract: A side carry carton having a top wall and a front wall interconnected by a flap forming the manufacturer's joint and hand hole panel formed in the front wall in part by a fold line spaced from the top wall is provided with an extension foldably connected to the manufacturer's joint forming the flap by a first fold line co-extensive with the hand hole forming fold line. The first fold line impairs folding of the extension into the carton at an angle of over approximately 90.degree.. Preferably the extension will extend the full length of said manufacturer's joint flap and said front wall. Folding of said hand hole forming panel into the carton causes the extension to fold relative to said manufacturer's joint flap whereby the hand hole is reinforced and the binding of the front wall of the carton is impaired.
