Abstract: A divider that has a die-cut board that is grease resistant coated on both sides and is scored to define a plurality of alternative valley and peak folds. There is at least one perforated line that passes through all of the valley and peak folds. The divider may taper at its sides from the peak folds to neighboring ones of the valley folds. Two perforated lines may be provided to sever the tapers from the sides to leave the sides substantially reside in parallel planes with respect to each other.
