Abstract: File binder structure including multiple bent hooks arranged side by side. One end of the bent hooks is integrally connected together by a connecting strip. The other end of the bent hooks is bent into short plates. A stop slat with I-shaped cross-section is connected to the open end of the bent hooks. The connecting strip and short plates are respectively inserted into two channels formed on two sides of the stop slat. The bent hooks are conducted through the row of holes of the papers and then the stop slat is fitted with the short plates of the bent hooks and the connecting strip to fix the papers. It is very easy to assemble the stop slat with the bent hooks and disassemble the stop slat from the bent hooks. Therefore, it is very convenient to increase or decrease the number of the papers or replace the papers.

Abstract: A binder for releasably retaining loose-leaves. The binder has a front cover that lies flatly beneath its back cover when the binder is open 360 degrees. The rings of the binder can rotate around an edge of the flatly-folded cover to enable loose-leaves to lie flat above and below the cover. The binder also has a skeleton with a minimal cross-section spine which may be partially or completely embedded in a cover and rotates in relation to parallel front and back covers when the binder is open 360 degrees. The front cover, middle cover and back cover are connected in a way so that they do not interfere with the rotation of the rings. Mechanisms to open and close the rings of the skeleton to allow addition or removal of loose-leafs, and ring shapes to optimize or stabilize the capacity of the binder during operation are also disclosed.

Abstract: The present invention provides an inflatable binder which has multiple air pockets which can be inflated by one or more air inlets. The binder is secured closed with a zipper or other enclosure. The material of the binder is a plastic sheet material or the like which provides for a water resistant binder. The inflated binder also provides cushioning to protect contents of the binder if dropped. In one embodiment, the front cover of the binder may have a central flat area surrounded by inflatable areas defining a frame, such that visual materials may be displayed from an inner pocket.

Abstract: An improved structure of a combination file folder includes a pair of clip boards and a connection board which mounted together to form a file folder. The file folder is made from plastic materials and can be detached from one another. Thus, the packaging and transportation costs are greatly reduced, as the file folder does not occupy a large space. Based on the need of the size of the file folder, the change of the connection board can satisfy the needs of the consumers.

Abstract: A double vision binder includes a front cover, a rear cover and a binding portion; a large transparent pocket is formed on the front cover of the binder by a layer of transparent sheet material bonded to the front cover on three sides; and additional smaller transparent pockets are bonded to the first transparent layer, so that a large sheet of background visual material may be inserted in the large pocket, with an overlay of additional visual material in the small pockets. the first layer may extend over the entire outer surface of the binder to provide additional pockets on the rear cover and on the binding portion of the assembly. A plurality of the small pockets may be formed from a single transparent sheet, with pockets separated by bonding lines.

Abstract: A notebook binder device having a first and second member. The first member having a front cover section. The front cover section having a central opening defining a window. The first member includes a connecting fold. The second member having a transparent, see through, cover and a back. When the first and second members are connected the back is viewed through the window and the transparent middle cover section. The second member includes a connecting fold suitable for connecting the connecting fold of the first member and for connecting the transparent cover section. Rivets and other connecting devices are adapted to connect the first and second members. Additionally, the rivets include male and female paper holding members for holding papers between the front and back covers.
