Abstract: A safety matchbook is constructed with the usual front cover which tucks beneath a lower flap to close the matchbook. A ridge mounted on the underside of the flap is provided with a central opening. A projection mounted on the front cover at an off center location fits through the opening in order to interlock with the ridge and latch the matchbook in its closed position. To open the matchbook, the cover must be flexed laterally and simultaneously pushed downwardly to pass the projection by a stop member. The flap must then be raised in order to permit the projection to clear a ramp structure located within the ridge opening.
