Abstract
A binder comprising: (a) a front cover; (b) a rear cover; (c) a spine extending between and connecting the front cover and the rear cover, the spine being made of a different material than the front cover and the rear cover; and (d) a binder mechanism; wherein the spine is a reinforced polymer that is sufficiently flexible to allow the front cover, the rear cover, or both to move relative to the spine so that the front cover, the rear cover, or both are openable and closeable.
Claims16
A binder comprising:
- a) a front cover;
- b) a rear cover;
- c) a spine extending between and connecting the front cover and the rear cover, the spine including:
- i) expansion regions that include an excess of material forming one or more pleats, wherein the spine has a width when the expansion regions are in an empty position and the one or more pleats of the expansion regions are configured to expand the width of the spine upon unfolding into a filled position so that the width of the spine in the filled position is greater than the width of the spine in the empty position;
- and
- d) a binder mechanism;
- wherein the spine is a reinforced polymer that is sufficiently flexible to allow the front cover, the rear cover, or both to move relative to the spine so that the front cover, the rear cover, or both are openable and closeable, and the spine is free of hinges.
