Claims10
A partitioned box comprising
- A. first and second pairs of parallel wall panels hinged together to form a tube,
- B. a first pair of similar bottom panels hinged to the bottom edges of the first pair of wall panels,
- C. a second pair of similar bottom panels hinged to the bottom edges of the second pair of wall panels, said two pairs of bottom panels interfitting to completely close the bottom of the box,
- D. a first pair of similar partition panels hinged to the edges of the first pair of bottom panels parallel to their hinges with the wall panels,
- E. a second pair of partition panels hinged to the edges of the second pair of bottom panels parallel to their hinges with the wall panels,
- F. means for hingedly connecting a side edge of one partition panel in the second pair to one partition panel in the first pair,
- G. means for hingedly connecting a side edge of the other partition panel in the second pair to the other partition panel in the first pair,
- H. a substantially vertical slot in each first pair partition panel for receiving an opposing second pair partition panel, said slot extending all the way to the top of said partition panel, and
- I. a relatively large tab hinged to the upper edge of each first pair partition panel for bridging the slot therein to retain the second pair partition panel within said slot, said tabs being accessible to function as carrying handles for the box and being foldable down against the tops of the partition panels when a cover is placed on the box.

A blank for forming a lock bottom partitioned box comprising
- A. a series of four hinged together wall panels, alternate ones of said panels of being substantially identical,
- B. a first pair of substantially similar bottom panels hingedly connected to the bottom edges of alternate ones of said wall panels,
- C. a second pair of substantially similar bottom panels, hingedly connected to the bottom edges of the remaining wall panels in the series,
- D. a pair of transverse partition panels hinged to the edges of the first pair of bottom panels parallel to their hinged connections with the wall panels,
- E. an elongated slot in each transverse partition panel said slot extending from the hinge between that panel and the bottom panel in a direction substantially perpendicular to that hinge for an appreciable distance along the transverse partition panel,
- F. a slit in each first pair bottom panel, each said slit being parallel and contiguous to the slot in the transverse partition panel hinged to that bottom panel, and
- G. a pair of longitudinal partition panels hinged to the edges of the bottom panels in a second pair parallel to their hinged connections with the wall panels, said longitudinal partition panels extending from said hinges for a distance slightly less than the length of said slots.
