A filing container in accordance with claim 1, wherein said indexing means comprises first and second coacting indexing projections, one of said projections being disposed on the inside surface of one of said outer portion sidewalls, the other of said projections being disposed on the outside surface of the one of said inner portion sidewalls generally adjacent said one of said outer portion sidewalls, said indexing projections being adapted for releasable coacting engagement with each other for restraining relative pivotal movement of said inner file portion to said open position after movement thereof from said closed position.

Claim 5

A filing container in accordance with claim 3, wherein said one of said sidewalls on which said second indexing projection is disposed defines an arcuate recess extending radially about the pivotal axis of said inner file portion, said second indexing projection being positioned generally within said arcuate recess so that said first indexing projection is relatively movable within said arcuate recess during movement of said inner file portion between said open and closed positions.

Claim 6

A filing container in accordance with claim 1, including means for releasably locking said inner file portion in said closed position with respect to said outer support portion.

Claim 7

A filing container in accordance with claim 1, including stop means associated with said outer portion sidewalls opposite said outer portion front wall, said stop means being engageable by said inner file portion in the open position thereof for limiting opening pivotal movement of said inner file portion to an arc of less than 180 degrees.

Claim 8

A filing container in accordance with claim 6, wherein said end wall of said inner file portion is disposed at an angle with respect to the rear wall of the file portion equal to said arc of pivotal movement of said inner file portion, said means pivotally connecting said inner file portion and said outer support portion being positioned such that said end wall of said inner file portion is aligned and flush with respective ones of the edges of said outer portion sidewalls in the open position of said inner file portion, with said inner file portion extending beyond the respective opposite ones of the edges of said outer portion sidewalls.

Claim 9

A container for filing generally flat objects such as magnetic disks, comprising: a generally rectangular outer support portion having a pair of laterally spaced sidewalls, and spaced front and rear walls extending between the respective opposite ends of said sidewalls, said rear wall including a stop portion; an inner file portion disposed generally within said outer support portion and having an open-ended configuration for receiving said articles therein, said inner file portion including an end wall, a pair of laterally spaced sidewalls extending from said end wall, and spaced front and rear walls extending between said file portion sidewalls; means pivotally connecting each of said inner file portion sidewalls to a respective one of said outer portion sidewalls, whereby said inner file portion is relatively pivotal about an axis with respect to said outer support portion through an arc of less than 180 degrees, said inner file portion being pivotal from a closed position wherein said inner file portion is substantially nested within said outer support portion, to an open position wherein said inner file portion is disposed in generally upstanding relation to said outer support portion in engagement with said stop portion for permitting access to the articles in said inner file portion; said inner file portion including pivot means whereby said front wall thereof is pivotal toward and away from the rear wall thereof when said inner file portion is in said open position to facilitate access to said articles; and indexing means for preventing unrestrained relative pivotal movement of said inner file portion to said open position after said inner file portion has been relatively moved from said closed position.

Claim 10

A container for filing generally flat objects such as magnetic disks, comprising: a generally rectangular outer support portion having a pair of laterally spaced sidewalls, and spaced front and rear walls extending between the respective opposite ends of said sidewalls, said rear wall including a stop portion; an inner file portion disposed generally within said outer support portion and having an open-ended configuration for receiving said articles therein, said inner file portion including an end wall, a pair of laterally spaced sidewalls extending from said end wall, and spaced front and rear walls extending between said file portion sidewalls; means pivotally connecting each of said inner file portion sidewalls to a respective one of said outer portion sidewalls, whereby said inner file portion is relatively pivotal about an axis with respect to said outer support portion through an arc of less than 180 degrees, said inner file portion being pivotal from a closed position wherein said inner file portion is substantially nested within said outer support portion, to an open position wherein said inner file portion is disposed in generally upstanding relation to said outer support portion in engagement with said stop portion for permitting access to the articles in said inner file portion; said inner file portion including pivot means whereby said front wall thereof is pivotal toward and away from the rear wall thereof when said inner file portion is in said open position to facilitate access to said articles; and indexing means for preventing unrestrained relative pivotal movement of said inner file portion to said open position after said inner file portion has been relatively moved from said closed position.

Claim 11

A filing container in accordance with claim 8, wherein said indexing means comprises first and second coacting indexing projections, one of said projections being disposed on the inside surface of one of said outer portion sidewalls, the other of said projections being disposed on the outside surface of the one of said inner file portion sidewalls generally adjacent said one of said outer portion sidewalls, the one of said inner and outer portion sidewalls on which said second indexing projection is disposed defining an arcuate recess extending radially about said pivot axis of said inner file portion, said second indexing projection being disposed in said arcuate recess such that during relative pivotal movement of said inner file portion, said first indexing projection is relatively movable within said arcuate recess and said first and second projections are releasably engageable with each other for restraining movement of said inner file portion toward its open position after movement thereof from said closed position.

Claim 12

A filing container in accordance with claim 9, including cam means associated with one of said indexing projections engageable by the other one of said projections during relative pivotal movement of said inner file portion from said open to said closed position whereby movement of said inner file portion from said open to said closed position is relatively unrestrained by engagement of said first and second indexing projections with each other.

Claim 13

A filing container in accordance with claim 10, wherein said cam means comprises a cam surface positioned in said arcuate recess adjacent said second indexing projection, said cam surface being engageable by said first indexing projection during relative movement of said inner file portion from said open position to said closed position.

Claim 14

A filing container in accordance with claim 8, wherein said end wall of said inner file portion is disposed at an angle with respect to the rear wall of the file portion equal to said arc of pivotal movement of said inner file portion, said means pivotally connecting said inner file portion and said outer support portion being positioned such that said end wall of said inner file portion is aligned and flush with respective ones of the edges of said outer portion sidwalls in the open position of said inner file portion, with side inner file portion extending beyond the respective opposite ones of the edges of said outer portion sidewalls.

Claim 15

A filing container in accordance with claim 8, wherein said outer support portion includes means projecting inwardly of said front wall thereof, said open end of said inner file portion being disposed in generally confronting relation to said inwardly projecting means when said file portion is in said closed position.

Claim 16

A filing container in accordance with claim 8, wherein the inside surface of said end wall of said inner file portion defines a plurality of laterally extending ridges.
