Partition divider

A partition divider formed from a cut and scored blank of flat sheet material such as paperboard or the like comprising:

• a. a flat blank;
• b. at least one partition divider erectable from the plane of said blank comprised of:
• c. a partition member and a partition position maintaining member defined by first cut lines and laterally spaced second cut lines normal to said first cut lines;
• d. said partition member and said partition position maintaining member being further defined by a common hinge line formed in the material of the blank and extending continuously between said laterally spaced second cut lines;
• e. said partition member being rotatable independently of said partition position maintaining member about said common hinge line out of the plane of said blank through an angle of approximately 90.degree. to an erected position;
• f. said partition position maintaining member being rotatable independently of said partition member about said common hinge line in the same direction through an angle of approximately 180.degree. and into the opening resulting from the rotation of said partition member to maintain the erected position of said partition member.
