  • Patent number: 5622385
    Abstract: A removable, reusable, wrap-around cover for a paperback book consisting of a single sheet of semi-rigid synthetic plastic material, vertically scored with multiple lines to allow it to fit around varying thickness of book, with two pairs of flaps on each side and a single loop of elastic at the center of the sheet. The main sheet wraps around the covers and spine of the book, and folds over the edges of the front and rear covers to keep the cover on the book. The flaps are formed such that when the main sheet has been folded around the book, they can be folded onto the insides of the covers and linked together so that the two pairs of flaps form a pair of bands that keeps the edges of the main sheet folded around the covers of the book. The elastic loop stretches around the entire assembled cover and book, and keeps the book shut to protect it from damage.
