Folded book dust cover - has two panels with edge flaps for use as loose leaf folder or postal packet

摘要

The dust cover or jacket for a book consists of two main panels (1,2) connected by a spine (9), each panel having three flaps, (3,4,5 and 6,7,8). Each panel has trapezium shaped flaps (3,5 and 6,8) top and bottom, and a rectangular end flaps (4 and 7). When used conventionally, the top and bottom flaps are folded inwards over the book covers and the end flaps are folded inwards on top of them. Alternatively one (e.g. 4) of the end flaps can be folded over the other (7) to hold loose leaves. One end flap includes holes (o) at the top, bottom and outside edges for securing tapes and elastic bands. In another method, the flaps can carry an adhesive so that the cover can be used as an envelope for postage.
