Abstract
Abstract A multi-compartment collapsible container made from a single integral blank is folded up and appropriately spotted with adhesive so that compartment forming panels extending from sections of the end walls and bottom walls lie in surface-to-surface relation initially with the end walls and side walls. The container thus manufactured may be shipped flat and erected at the place of the user by pushing on opposite ends of the folded carton in order to erect the carton with a longitudinal central partition and additional partitions extending from the longitudinal central partitions towards the side walls to create alternatively an erectible carton having eight cells in two rows of four with the cells being of substantially equal size or a carton having a pair of cells at each end, totalling four end cells with two larger cells intermediate the end cells which larger cells may themselves be convertible into smaller cells of equal size with the end cells totalling eight in all.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
313 words
An erectable, unitary multicell carton comprising a pair of side walls and a pair of end walls connected to form a rectangular carton, a bottom wall comprising a pair of bottom panels each extending from the lower edge of one of the side walls, each of said bottom panels extending longitudinally of the carton between the end walls to form a single bottom wall which has a juncture line along the longitudinal axis of the carton; central partition panels extending upwardly from the bottom wall panels at the longitudinal axis of the carton when the carton is erected, said central partition panels extending parallel to the side walls; first additional partition panels extending from the end walls and second additional partition panels extending from the first mentioned central partition panels extending from the bottom walls; said first additional partition panels extending from the end walls and said second additional partition panels extending from said bottom wall panels cooperating to form partitions parallel to said central partition panels; said first additional partition panels each having third additional partitions connected normal thereto and extending along said longitudinal axis to form end sections of the central partition of the erected carton; said end sections aligned with said central partition panels from the bottom wall panels to complete the longitudinal partition; said central partition panels extending from the bottom wall panels having fourth additional panels foldably connected thereto and positioned centrally of said end walls and at right angles to said central partition panels extending from the bottom wall, wherein said carton when erected forms a carton with a pair of cells at one end of size equal to each other, a pair of cells at the opposite end of a size equal to each other and a pair of central cells on each side of the longitudinal partition between said first mentioned two pairs of cells.
Claim 2
Dependent Claim
313 words
An erectable, unitary multicell carton comprising a pair of side walls and a pair of end walls connected to form a rectangular carton, a bottom wall comprising a pair of bottom panels each extending from the lower edge of one of the side walls, each of said bottom panels extending longitudinally of the carton between the end walls to form a single bottom wall which has a juncture line along the longitudinal axis of the carton; central partition panels extending upwardly from the bottom wall panels at the longitudinal axis of the carton when the carton is erected, said central partition panels extending parallel to the side walls; first additional partition panels extending from the end walls and second additional partition panels extending from the first mentioned central partition panels extending from the bottom walls; said first additional partition panels extending from the end walls and said second additional partition panels extending from said bottom wall panels cooperating to form partitions parallel to said central partition panels; said first additional partition panels each having third additional partitions connected normal thereto and extending along said longitudinal axis to form end sections of the central partition of the erected carton; said end sections aligned with said central partition panels from the bottom wall panels to complete the longitudinal partition; said central partition panels extending from the bottom wall panels having fourth additional panels foldably connected thereto and positioned centrally of said end walls and at right angles to said central partition panels extending from the bottom wall, wherein said carton when erected forms a carton with a pair of cells at one end of size equal to each other, a pair of cells at the opposite end of a size equal to each other and a pair of central cells on each side of the longitudinal partition between said first mentioned two pairs of cells.
Claim 3
Dependent Claim
24 words
The erectable, multicell carton of claim 1, wherein said central partition panels are longer than the first additional panels extending from said end walls.
Claim 4
Dependent Claim
28 words
The erectable, multicell carton of claim 2, wherein the central cells formed by said central partition panels are double the size of the cells adjacent said end walls.
Claim 5
Dependent Claim
69 words
The erectable, multicell carton of claim 2, wherein said central cells formed by said central partition panels are selectively available as cells of double the size of the pairs of cells at each end of the carton and, by reason of being provided with said fourth additional panels foldable out transverse to said central partition panels, are each convertible individually into cells of size equal to the end cells.
Claim 6
Dependent Claim
74 words
The erectable, multicell carton of claim 4, wherein said carton may be utilized as an eight-cell carton with the cells of equal size and selectively as a seven-celled carton with one of the two central cells having its foldable panel folded back to provide a single, larger compartment and also selectively usable as a six-celled carton with two pairs of end cells of equal size and the two compartments between them of double size.
Claim 7
Dependent Claim
22 words
The erectable, multicell carton of claim 1, wherein the top edges of said central longitudinal panels have retainer panels foldably connected thereto.
Claim 8
Dependent Claim
23 words
The erectable, mutlicell carton of claim 1, wherein the top edges of the end walls have duct excluding retainer panels foldably connected thereto.
Claim 9
Dependent Claim
78 words
The erectable multi-cell carton of claim 4, wherein the carton consisting of eight cells with certain of the cells being convertible is formed as a double carton consisting of four rows of four cells each at east one pair of cells in each row being convertible, said double carton comprising two basic cartons having a common longitudinal side wall to form a pair of rows of cells, outer and adjacent walls of the cartons being adhesively secured together.
