Abstract
A matchbook which requires complete closure to obtain a usable match-striking surface. Only then does an interior-mounted row of spaced protuberances occupy similarly spaced, complementary holes in a striking strip on the matchbook's openable flap to provide a continuous area of adequate size for match-striking purposes. A latch system is an additional safety feature; the elementary moves of young children will not open it, because the matchbook's openable flap remains trapped by an inwardly-turned, slotted ridge unless appropriate coordinated actions are taken.
