发明名称 Removable plastic binding
摘要 A removable plastic binding system is disclosed including a channel member and a removable plastic binding receivable in the channel member. The channel member is mounted to the backbone of a book cover. The removable binding, which is slidably received in the channel member, has a plurality of curled loops for retaining paper leaflets such as sheets of blank checks to the book cover. The removable binding has retaining tabs extending from a base portion below the loops. The tabs are bent such that they all lie substantially in the same plane to facilitate sliding of the binding into the channel member. The removable binding including the retaining tabs, base portion and curled loops is formed from a single, contiguous sheet of plastic material.
