Abstract
Abstract An organic plastic matchbook cover having continuous front, back and side walls, and that is closed at its bottom and generally open at its top. The walls and bottom define a generally wedge-shaped interior cavity having the size and shape necessary to receive a conventional paper matchbook therewithin. An opening is provided in the front wall of the cover in position to overlie the striking surface of the matchbook, and a second opening is provided in the back wall to permit a thumb or finger to engage the back of the matchbook. A holding tab projects from the top of the back wall partially across the top of the cover towards the front wall in position to overlie and engage the top of a matchbook positioned in the cavity, and a locking tab projects inwardly from each of the side walls.
