Abstract
Abstract Carton constructions formed from corrugated blanks are disclosed. The automatic setup cartons are formed from blanks having side panels from which top and bottom panels extend on either side thereof. Tabs and slots, if provided, lock the carton in the assembled condition and are carried on the bottom panels which are folded and glued in a manner so as to provide the automatic setup feature.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
180 words
An automatic setup carton formed from a precut corregated paper blank comprising a. four side panels including two outer panels and two inner panels disposed on said blank defined by score lines between adjacent panels, b. four bottom panels each extending downwardly from one of said side panels and defined by a score line therebetween, and c. glue flaps defined by score lines on the two bottom panels extending downwardly from said inner panels to adhesively secure the remaining bottom panels thereto, one of said inner bottom panels and one of said outer bottom panels being secured in over and under relationship wherein one end thereof is over one of the adjacent panels while the other end thereof is under the other adjacent bottom panel, said carton being maintained in a flat condition prior to setup with the bottom panels folded onto the side panels and upon setup the side panels are spread apart to form a rectangular configuration causing the interconnected bottom panels to automatically deploy in said over and under relationship to form the bottom of said carton.
Claim 2
Dependent Claim
180 words
An automatic setup carton formed from a precut corregated paper blank comprising a. four side panels including two outer panels and two inner panels disposed on said blank defined by score lines between adjacent panels, b. four bottom panels each extending downwardly from one of said side panels and defined by a score line therebetween, and c. glue flaps defined by score lines on the two bottom panels extending downwardly from said inner panels to adhesively secure the remaining bottom panels thereto, one of said inner bottom panels and one of said outer bottom panels being secured in over and under relationship wherein one end thereof is over one of the adjacent panels while the other end thereof is under the other adjacent bottom panel, said carton being maintained in a flat condition prior to setup with the bottom panels folded onto the side panels and upon setup the side panels are spread apart to form a rectangular configuration causing the interconnected bottom panels to automatically deploy in said over and under relationship to form the bottom of said carton.
Claim 3
Dependent Claim
21 words
The carton of claim 1 wherein one of said bottom panels is larger than the others to form an overlapping bottom.
Claim 4
Dependent Claim
26 words
The carton of claim 1 further including four top panels each extending upwardly from one of said side panels and defined by a score line therebetween.
Claim 5
Dependent Claim
24 words
The carton of claim 1 further including locking means on said bottom panels actuated during setup for securing said carton in the setup condition.
Claim 6
Dependent Claim
46 words
The carton according to claim 4 wherein said locking means comprise: a. tabs on two of said four bottom panels; and b. locking slots on the remaining two bottom panels aligned whereby on setup each tab passes into one of said slots and is retained therein.
Claim 7
Dependent Claim
29 words
The carton of claim 1 further including partition means extending from two of said bottom panels for dividing the interior of said carton into at least two separate cells.
Claim 8
Dependent Claim
61 words
The carton according to claim 6 wherein said partition means includes: a. a stationary flap defined by a score line between said bottom panel and said flap; and b. a movable flap attached to said stationary flap and defined by a score line therebetween, said stationary and movable flaps being deployed inside said carton during setup to form said separate cells.
Claim 9
Dependent Claim
60 words
The carton according to claim 7 wherein said movable flap has a further portion for engaging a side panel of said carton whereby rotation of one or both of said movable flaps to a position perpendicular to said stationary flaps forms a three- or four-celled carton, respectively, said further portion serving to secure said movable flap in the perpendicular position.
Claim 10
Dependent Claim
30 words
The carton according to claim 4 further including partition means extending from two of said bottom panels for dividing the interior of said carton into at least two separate cells.
Claim 11
Dependent Claim
36 words
The carton of claim 1 wherein a second automatic setup carton of slightly larger dimensions is employed to seal the open top of the first carton thereby to provide a sealed container formed without manual sealing.
