Bonded object, e.g. booklet, notebook and address book, has two cover pages and back part, where multiple sides are rotably fixed with respect to back part

摘要

The bonded object has two cover pages (2',3') and a back part (4'), where multiple sides (5') are rotably fixed with respect to the back part. The sum of the widths of the two flaps (6',7') is equal to the width of the back part. The magnetic attraction between the two elements of the magnet pair holds a longitudinal edge of the former flap against the longitudinal edge of the latter flap, when the bonded object is closed.
