Abstract: A folder includes a spine having a base and first and second spine hinge portions. The spine defines a longitudinal axis and has an exterior surface that is curved around the longitudinal axis. The folder also includes a first cover having a first cover hinge portion pivotably attached to the first spine hinge portion. The first cover has a first curved portion with an exterior surface that is curved around the longitudinal axis. The folder further includes a second cover having a second cover hinge portion pivotably attached to the second spine hinge portion. The second cover has a second curved portion with an exterior surface that is curved around the longitudinal axis. The spine and the first and second curved portions together define a generally rounded contour around the longitudinal axis when the folder is in a closed position.

Abstract: A folder that has a spine that is hinged to two covers. The preferred covers have a convex portion that extends around a binding mechanism over most of the distance of that the binding mechanism protrudes inwardly from the spine support portion that extends outwardly with respect to a portion of the cover pivotably attached to the spine. A concave portion is located adjacent the convex portion towards the free end of the binder. The preferred folder portion of the binder has projections that are deformed through openings in the binding mechanism to secure the binding mechanism to the folder. A preferred cover has an arcuate cross-section extending parallel to the hinges.

Abstract: A folder that has a spine that is hinged to two covers. At least one of the covers has a support portion that extends outwardly with respect to a portion of the cover pivotably attached to the spine. The support portion is located between the hinged portion and another portion disposed opposite therefrom.

Abstract: A support element for optical disks, compact disks (CDs) or containers therefor which is able to maintain the disks or containers in a substantially vertical position. The support element includes a casing which includes a first part and a second part, the second part being hingedly connected to the first part such that the first and second parts each have a free end. The casing is structured and arranged to have a first closed position in which the first and second parts are mutually superposed and a second open position in which the free end of the first part is angularly displaced from the free end of the second part in a first direction such that the first and second parts are able to support the disks or their containers in a substantially vertical position.
