Claim 1
Independent Claim
181 words
A carton formed of a container board comprising: a. four side walls folded at right angles to one another to form a hollow box shape; b. two end panels attached to the bottom portion of two of said side walls opposite one another and folded inwardly at right angles to the side walls to which they are attached; each of said end panels being cut at its center in a direction perpendicular to the side wall; c. two other end panels attached to the bottom portion of the other two of said side walls and folded inwardly at right angles to the side wall to which they are attached; d. partition panels attached to said other end panels and passing through said cut end panels into the interior of the carton formed by the four walls, said partition panels being partially severed from said other end panels whereby the severed portion may be folded at 90 degrees to the remaining portion so as to define four cells within said carton, and e. said partition panels extend the depth of the carton.

Claim 3
Dependent Claim

A container blank adapted to be folded into a box-shape container comprising: a. a rectangular blank of container board divided into four panels by vertical crease lines; b. four bottom flaps carried by said four panels and separated therefrom by horizontal crease lines; c. two of said bottom flaps each at an opposite side of one of said four bottom flaps having vertical cuts therein which are perpendicular to said crease lines; d. said one flap and the remaining of said bottom flaps carrying divider panels having a width equal to that of the flap, but separated therefrom by a horizontal cut for one half the width, said carton being foldable into a box-shape structure with a self locking bottom closure formed of the four bottoM flaps and the divider panels, e. and a pair of crease lines normal to each other in each divider panel intersecting each other at an inboard end of their associated horizontal cuts with one of said pair of crease lines forming a coincident extension of its associated horizontal cut.
