ABSTRACT:
A multiple pocket, expandable envelope is formed by folding panels of a planar, unitary blank relative to each other. The envelope has two pair of front and back panels hingedly coupled along a common end edge. Each front and back panel includes a front and back divider panel therebetween to define six pockets within the envelope. Each front panel is hingedly coupled to a front divider panel along a fold line at one side thereof. Each back panel is hingedly coupled to a back divider panel along a fold line at one side thereof. A plurality of side panels hingedly couple each front panel to a front divider panel at the other side of the front panel, each back panel to a back divider panel at the other side of the back panel, and the front and back divider panels at each pair to each other. One of the front panels in each pair is hingedly coupled to one of the back panels in an adjacent pair to form the six-pocket, expandable envelope.
