An index tab system for useful organization of articles in objects such as hanging folders, file folders, expandable folders, index cards, index dividers, notebooks, binders, and the like. The index tab system provides a plurality of index tab forming structures that can be affixed to any of the above mentioned objects for indexing the articles or the contents therein. The plurality of index tab forming structures includes interlocking structures for selective formation of tab cavities and selective placement of the tab members along the object.

Index tab system

A plastic tab for indexing or marking a folder or an edge portion of an article such as an organizer or storage system. The lower portion of the tab has two downwardly extending walls, between which an edge of the folder or other article may be placed. The downwardly extending walls are configured and adapted to create an interference fit when the folder or other article is inserted between the walls of the tab. The interference fit enables the tab to remain securely in the desired position along the edge portion. The tab is made of a flexible polymeric material so that it may be mounted, re-positioned or removed easily. Removal of the tab from a wall edge causes the walls to flex apart and thereby eliminate or minimize the interference fit between the tab lower walls and the article on which the tab is mounted. Removal of the tab is therefore a smooth and simple operation that minimizes breakage of the tab or damage to the folder, organizer or storage medium.

Positionable indexing tab

An expandable folder is provided which includes a front panel member, a rear panel member, and an expandable gusset which connects the panel members and forms the bottom and sides of the folder. Reinforcing means are provided upon critical or highly stressed locations to enhance the durability and useful life of the folder. Various types of reinforcement are provided about and, preferably, over the top of the gusset. The end portions of the gussets along the sides and, where applicable, the bottom, preferably have a width which is at least twice the width of the gusset folds. The outer surfaces of the inner front and rear panel members are also reinforced to strengthen the folder at least in the areas where the gusset is attached, and, for best results, on the entire outer surfaces of the panels.

Reinforced expandable folders

A reinforced shelf filing folder having front and rear panel members connected along a fold line and a tab member connected to a first side edge of the rear panel member. Reinforcement is applied to both sides of the tab member and to the outer surface of the fold line extending onto the adjacent surfaces of the front nd rear panel members. Finally, additional reinforcement means is optionally applied to the outer surfaces of the front and rear panel members, disposed along a side portion of the rear panel member opposite the first side edge and over the fold line to a corresponding portion on the front panel member. Alternatively, the additional reinforcement can be applied to the outer and inner sides of the front panel member along the first side edge. These reinforcements increase the wear resistance and life of the folder.

Reinforced shelf filing folders

A folder that hangs on a standard frame in office storage equipment which includes a sheet of flexible material folded at a medial line to form a bottom edge with an exterior surface and front and rear portions joined at the bottom edge, each of front and rear portions having an interior surface and an exterior surface, wherein the ends of said front and rear portions removed from said bottom edge are folded over to form top terminal folded portions, a reinforcing layer comprising one or more strips of plastic material laminated onto the folder and applied to substantially all of the exterior surfaces to increase the wear resistance, strength and life of said folder, and means for hanging the folder on the frame.

Hanging laminated folder

A hanging folder has reinforcing strips along its top and bottom edges, and color contrasted easy-insert label slots. These strips and contrasting slots protect against wear to the folder and thus prolong the usefulness of the folder.

A method for manufacturing improved paper office supplies comprises determining which critical areas or portions of the office supplies are prone to wear and tear, and applying reinforcement upon or adjacent to those critical areas or portions to increase the strength and resistance of the office supplies to such wear and tear. This invention also provides some examples of reinforced paper office supplies.
