Abstract
Abstract A partitioned carton has front and back panels joined by perpendicular side panels. Each panel has a hinged bottom flap defining a part of the bottom wall of the carton. A first partition panel extends from the middle of the back panel to the middle of the front panel. This panel is about one half the height of the carton with its lower edge being spaced above the bottom wall of the carton. A second partition panel, perpendicular to the first, extends upwardly to the lower edge of the first panel from the bottom flap of the back panel. The second panel has a notch in its upper edge which is received in the lower edge of the first panel to lock the partition panels in place. Each of the bottom flaps is permanently secured to only one of the adjacent bottom flaps. The carton can readily be erected from a collapsed condition without glueing and easily re-collapsed without damage.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
233 words
A partitioned carton comprising: a pair of generally parallel front and back panels; a pair of generally parallel side panels connecting said front and back panels to form a generally rectangular tube; bottom flaps extending from the lower edge of each of the above identified panels, said bottom flaps extending along a single plane; at least one first partition panel having one end secured to said back panel and the opposite end secured to said front panel, said partition panel being parallel to said side panels and having a substantially linear lower edge portion spaced upwardly from the lower edges of said front, back and side panels, said first partition panel including a central tab along said linear lower edge portion projecting downwardly from the linear lower edge portion thereof; and at least one second partition panel extending upwardly from one of said bottom flaps, said second partition panel being perpendicular to said first partition panel and having a tab, with a central notch, projecting inwardly from the top edge thereof to frictionally lock said second partition panel with said first partition panel along its linear lower edge portion, whereby said partition panels subdivide the rectangular tube into a plurality of compartments, the depth of said central notch being less than the extent of the downward projection of said central tab so that said central tab will bear against said second partition panel.
Claim 2
Dependent Claim
233 words
A partitioned carton comprising: a pair of generally parallel front and back panels; a pair of generally parallel side panels connecting said front and back panels to form a generally rectangular tube; bottom flaps extending from the lower edge of each of the above identified panels, said bottom flaps extending along a single plane; at least one first partition panel having one end secured to said back panel and the opposite end secured to said front panel, said partition panel being parallel to said side panels and having a substantially linear lower edge portion spaced upwardly from the lower edges of said front, back and side panels, said first partition panel including a central tab along said linear lower edge portion projecting downwardly from the linear lower edge portion thereof; and at least one second partition panel extending upwardly from one of said bottom flaps, said second partition panel being perpendicular to said first partition panel and having a tab, with a central notch, projecting inwardly from the top edge thereof to frictionally lock said second partition panel with said first partition panel along its linear lower edge portion, whereby said partition panels subdivide the rectangular tube into a plurality of compartments, the depth of said central notch being less than the extent of the downward projection of said central tab so that said central tab will bear against said second partition panel.
Claim 3
Dependent Claim
23 words
The carton defined in claim 1 further including means for securing each bottom flap to only one of the two adjacent bottom flaps.
Claim 4
Dependent Claim

Claim 9
Dependent Claim
24 words
The carton defined in claim 7, wherein the bottom flap carrying said second partition panel extends from the lower edge of said back panel.
Claim 10
Dependent Claim

Claim 11
Dependent Claim
30 words
The carton defined in claim 6 wherein the bottom flap from which said second partition panel extends at least partially overlaps each of the remaining bottom flaps of the carton.
Claim 12
Dependent Claim
