Abstract
Abstract A combination corrugated and fiberboard partition spacer in which the partitions are all slotted from one edge and in which the slots of longitudinal and transverse partitions are reversely oriented and colinearly aligned to form a multiple cell divider or spacer. The novelty of this combination corrugated and fiberboard partition resides in the provision of extra wide slots at selected slot sites of an otherwise all fiberboard partition spacer and the insertion in those extra wide slots of slotted corrugated partitions.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
190 words
A multi-cell spacer for maintaining the spacing and separation of articles contained within cells of the spacer, said spacer comprising a first set of identical, planar, generally rectangular partitions arranged in parallel spacial relationship, each of said partitions having parallel slots extending inwardly from one side edge, a second set of identical, generally planar, rectangular partitions arranged in parallel spacial relationship, each of said partitions of said second set having parallel slots extending inward from a side edge opposite the one side edge of the partitions of said first set, the partitions of said first set being perpendicular to the partitions of said second set when said partitions are assembled with said slots of the partitions of the first set interfitted and colinear with the slots of the partitions of said second set, and at least one of said partitions being constructed of multiple ply corrugated board and the remainder of said partitions being constructed of non-corrugated fiberboard, said corrugated partition being located at a preselected site within the assembled spacer such that it increases the vertical strength and crush resistance of the resulting combination fiberboard and corrugated board spacer.
Claim 2
Dependent Claim
190 words
A multi-cell spacer for maintaining the spacing and separation of articles contained within cells of the spacer, said spacer comprising a first set of identical, planar, generally rectangular partitions arranged in parallel spacial relationship, each of said partitions having parallel slots extending inwardly from one side edge, a second set of identical, generally planar, rectangular partitions arranged in parallel spacial relationship, each of said partitions of said second set having parallel slots extending inward from a side edge opposite the one side edge of the partitions of said first set, the partitions of said first set being perpendicular to the partitions of said second set when said partitions are assembled with said slots of the partitions of the first set interfitted and colinear with the slots of the partitions of said second set, and at least one of said partitions being constructed of multiple ply corrugated board and the remainder of said partitions being constructed of non-corrugated fiberboard, said corrugated partition being located at a preselected site within the assembled spacer such that it increases the vertical strength and crush resistance of the resulting combination fiberboard and corrugated board spacer.
Claim 3
Dependent Claim
203 words
A multi-cell spacer for maintaining the spacing and separation of articles contained within the cells of the spacer, said spacer comprising a first set of identical, planar, generally rectangular partitions arranged in parallel spacial relationship, each of said partitions having parallel slots extending inwardly from one side edge, a second set of identical, generally planar, rectangular partitions arranged in parallel spacial relationship, each of said partitions of said second set having parallel slots extending inward from a side edge opposite the one side edge of the partitions of said first set, the partitions of said first set being perpendicular to the partitions of said second set when said partitions are assembled with said slots of the partitions of the first set interfitted and colinear with the slots of the partitions of said second set, each one of said slots of said partitions being of a single width but at least one of said partitions having slots of increased width relative to other slots of said partitions, and at least one of said partitions being constructed of multiple ply corrugated board and the remainder of said partitions being constructed of non-corrugated fiberboard, said corrugated partitions being located within the wider slots of said partitions.
Claim 4
Dependent Claim
203 words
A multi-cell spacer for maintaining the spacing and separation of articles contained within the cells of the spacer, said spacer comprising a first set of identical, planar, generally rectangular partitions arranged in parallel spacial relationship, each of said partitions having parallel slots extending inwardly from one side edge, a second set of identical, generally planar, rectangular partitions arranged in parallel spacial relationship, each of said partitions of said second set having parallel slots extending inward from a side edge opposite the one side edge of the partitions of said first set, the partitions of said first set being perpendicular to the partitions of said second set when said partitions are assembled with said slots of the partitions of the first set interfitted and colinear with the slots of the partitions of said second set, each one of said slots of said partitions being of a single width but at least one of said partitions having slots of increased width relative to other slots of said partitions, and at least one of said partitions being constructed of multiple ply corrugated board and the remainder of said partitions being constructed of non-corrugated fiberboard, said corrugated partitions being located within the wider slots of said partitions.
Claim 5

A multi-cell spacer for maintaining the spacing and separation of articles contained within cells of the spacer, said spacer comprising a first set of identical, planar, generally rectangular partitions arranged in parallel spacial relationship, each of said partitions having parallel slots extending inwardly from one side edge, a second set of identical, generally planar, rectangular partitions arranged in parallel spacial relationship, each of said partitions of said second set having parallel slots extending inwardly from a side edge opposite the one side edge of the partitions of said first set, the partitions of said first set being perpendicular to the partitions of said first set when said partitions are assembled with said slots of the partitions of the first set interfitted and colinear with the slots of the partitions of said second set, each of said slots of said partitions being of a single width but varying in width from one slot to another within selected ones of said partitions such that there are least two different width slots within said selected ones of said partitions, and at least two of said partitions being constructed of multiple ply corrugated board and the remainder of said partitions being constructed of non-corrugated, single ply fiberboard, said corrugated partitions being located within the wider slots of said selected ones of said partitions.
