A method for closing a box ( 1 ) by folding a lateral closing flap ( 5 ) extending from an upper edge ( 6 ) of a lateral aperture ( 7 ) of the box ( 1 ) and having at least one foldable edge ( 8 ), while the box ( 1 ) is being moved along a packaging line (L) in a forward movement direction (W), includes the steps of folding the lateral flap ( 5 ) until a connection line ( 9 ) of the foldable edge ( 8 ) touches stop means ( 15 ), then folding the foldable edge ( 8 ) on the striking means ( 15 ) and toward the lateral aperture ( 7 ) of the box ( 1 ), so that an outer edge ( 8 a) of the foldable edge ( 8 ) interacts with contrast means ( 17 ), which keep elastically the edge ( 8 ) in a position raised with respect to a bottom wall ( 1 a) of the box ( 1 ), and lastly introducing the edge ( 8 ) into the box ( 1 ). A device for carrying out the methods has folding means ( 14 ) for folding the said lateral flap. Then first pusher means ( 16 ) fold the foldable edge ( 8 ) toward the box ( 1 ) against contrast means ( 17 ), while second pusher means ( 18 ) are disposed crosswise and in alignment the said contrast means ( 17 ) to strike the lateral flap ( 5 ) and insert the lateral flap into the box ( 1 ).
