Abstract An adjustable protective cover attachable to the exterior of either a casebound or a paperback book formed from flexible synthetic resin sheet material comprising two sections each having two overlying plies of said material connected permanently along three edges by heat-sealing to form pockets respectively positioned to receive the covers of a casebound or paperback book, one of said sections having one free edge extending laterally beyond the open edge of the pocket to provide a connecting panel adapted to extend around the spine of a casebound or paperback book, and adhesive means to connect the outer edge portion of said connecting panel to the other section of said cover to secure the sections together to provide a unitary cover. When used with paperback books, each of said pockets also is arranged to contain a thin stiffening board of substantially the same size as the covers of a paperback book which is to be received in the pockets, said boards being positioned adjacent the inner surfaces of said book covers when received within said pockets, whereby the entire exterior of a paperback book may be viewed through the transparent cover which overlies said outer surfaces thereof.

Claim 1
Independent Claim

A protective book cover adapted to extend around the exterior of the covers and spine of a casebound or paperback book, said cover comprising two similar sections formed from relatively transparent sheet stock of durable flexible thermoplastic synthetic resin, each section comprising at one end two overlying plies of said sheet resin of the same length but one ply being substantially narrower than the other and permanently connected by fusion along the narrow end edges and one intervening side edge to one end portion of the wider ply to form a pocket open along one edge to receive at least the outer end portion of one cover of a book, the opposite end of each wider ply of each cover section being of a length adequate to extend around the spine of a book and be disposed substantially in flat overlying relation with the corresponding opposite end of the other cover section, a strip of pliable sheet material having pressure-sensitive cement on one surface adapted to be applied over the terminal end portion of the outermost opposite end portion of the overlying opposite end portions of said sections and adhere thereto and the adjacent portion of the other opposite end portion to secure the two cover sections adjustably connected together to closely fit a selected book, and stiffening boards complementary in size to said pockets and slightly narrower than the cover of a book to be enclosed in said cover respectively positioned in each pocket and adapted to be disposed against the inner surface of a book cover when mounted within said cover to stiffen the covers of such book.

A protective book cover adapted to extend around the exterior of the covers and spine of a casebound or paperback book, said cover comprising two similar sections formed from relatively transparent sheet stock of durable flexible thermoplastic synthetic resin, each section comprising at one end two overlying plies of said sheet resin of the same length but one ply being substantially narrower than the other and permanently connected by fusion along the narrow end edges and one intervening side edge to one end portion of the wider ply to form a pocket open along one edge to receive at least the outer end portion of one cover of a book, the opposite end of each wider ply of each cover section being of a length adequate to extend around the spine of a book and be disposed substantially in flat overlying relation with the corresponding opposite end of the other cover section, a strip of pliable sheet material having pressure-sensitive cement on one surface adapted to be applied over the terminal end portion of the outermost opposite end portion of the overlying opposite end portions of said sections and adhere thereto and the adjacent portion of the other opposite end portion to secure the two cover sections adjustably connected together to closely fit a selected book, and stiffening boards complementary in size to said pockets and slightly narrower than the cover of a book to be enclosed in said cover respectively positioned in each pocket and adapted to be disposed against the inner surface of a book cover when mounted within said cover to stiffen the covers of such book.
