摘要 |
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.
