Claim 1
Independent Claim
192 words
An internal partition structure formed from a pair of similar partition sections disposed in interlocking engagement with each other to provide a plurality of cells within an outer container or wrapper, comprising: (a) a pair of similar partition sections, each being formed from a unitary blank of foldable paperboard or the like; (b) each of said partition sections including a pair of similar, elongated panels separated throughout the majority of their lengths but joined to each other in at least two places; (c) each of said panels being divided into at least two panel sections by at least one fold line extending transversely thereof; (d) adjacent panel sections of each panel being folded at angles to each other and each being disposed parallel to a panel section of the other panel; (e) each of the panel sections being foldably joined to a panel section of the other panel; (f) said panel sections having slots extending inwardly from corresponding edges thereof for at least half the width thereof to permit the panels of each section to be joined with corresponding panels of a similar but inverted panel section to accommodate interlocking engagement therebetween.
