COVER BINDERS AND METHODS OF USE |
摘要 |
A binder (B) formed by an elongated member with a first panel (22-1) that diverges at an opening with respect to a second panel (22-2). Both panels (22-1) (22-2) are demarked from the remainder of the binder (B) by an elongated indent line (23-1). The binder (B) includes an interior projection within the elongated member, beyond the first (22-1) and second (22-2) panels. A protuberance (25-1) on the inside of one of the panels (22-1) increases the grip against any inserted material (C). |
