ABSTRACT:
A six celled collapsible carton formed from a single cardboard blank which includes an automatic locking bottom and dividers which extend the entire height of the box. The carton is provided with four L-shaped dividers, two of which further include a central tab, spaced from both the top and bottom edges of the divider, for fixedly connecting an associated alternate divider to form a pair of cross-shaped divider members. One section of each pair of cross-shaped divider members overlaps to form a central wall. The side edge of each overlapping section is provided with a notch for creating an interengagement between the sections to add structural rigidity to the central wall. The side edges of the overlapping sections further include an arcuately shaped portion above the notches to facilitate the interengagement between the sections. The carton can be shipped in a flattened configuration and can be readily erected.
