Claim:
1. A divider, comprising: a die-cut board configured to move under manual force between a fully flattened condition and a completely folded condition and being movable from the fully folded condition to a released condition that is intermediate the fully flattened condition and fully folded condition upon release of the manual force, wherein the die-cut board has a plurality of scored lines spaced apart from each other and bending at each of the scored lines to form a series of alternating peak and valley folds between panels of the die-cut board, each of the scored lines having a depth sufficient for spring-back memory so that the release of the die-cut board from the completely folded condition results in the die-cut board unfolding to spread out into the released condition; a plurality of divider chambers each defined by a respective pair of the panels that has a respective one of the valley folds between the pair of the panels, the plurality of divider chambers being configured so that in the released condition the respective pair of the panels incline from the respective one of the valley folds; sides that taper from associated ones of the peak folds to neighboring ones of the valley folds so as to define a peripheral region at a level where the peak folds reside that is wider than a peripheral region defined at another level where the valley folds reside; and a water based, grease-resistant coating that coats faces of the panels.
