发明名称 Book with hidden spine
摘要 The present invention relates to bindings for books, wherein the spine is hidden behind an extension of the cover. Specifically, a piping element is inserted into a recess formed by a doubled-over center section of a cover of the book. Because of the structure of the piping element, the book is capable of laying flat when opened, while hiding the spine and concurrently protecting both the spine and other objects from damage.
