ABSTRACT:
A bottle-carton divider is formed by interlocking partitions each having a laterally projecting tab located along the length of, and extending into the half-height vertical slot of the partition by which the interlock with a cross-partition is effected. A tab-receiving opening is formed in each partition having an edge at a location spaced below but in alignment with an edge of the vertical slot. When the divider is assembled, the locking tab on any partition engages and overlaps the referred to edge of the tab-receiving opening of the interlocking partition, producing a pair of oppositely-directed abutment interfaces which restrain the locking tabs against disengagement in both directions, and in both the opened condition and one of the two possible collapsed conditions of the divider. The locking effect is enhanced and maintained by an additional edge or holding point at the bottom of each partition slot, facing but spaced away from the line of the opposite slot wall a distance equal to the thickness of the interlocking partition. Directly opposite, a cutaway of the opposite slot wall facilitates cutting and assembly of the partitions. Further, a laterally projecting partition support tab, adjacent to the open end of each partition slot, provides a second holding point for the interlocked partition, and the tab-receiving opening includes a seating edge extending perpendicularly to the slot axis and an arcuate portion at its opposite corner, which provide more firm engagement of the engaged locking tab.
