Abstract
Abstract A box for flowable material comprises a plurality of independent cells in which coextensive facing walls are secured together by a reenforcing sheet coextensive with and bonded by adhesive to such walls. To facilitate registry of adhesive, both faces of the reenforcing sheet have adhesive applied thereto, and bonding of the sheet to the walls is then effected.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
92 words
A multiple-cell box adapted for retention of material having cold-flow characteristics, said box comprising a plurality of independent paperboard cells having substantially coextensive facing walls, a flat substantially continuous paperboard reenforcing and securing sheet disposed between said walls, said paperboard sheet having opposed planar surfaces substantially coextensive with said facing walls, and adhesive bonding said planar surfaces to said facing walls over substantially the full extent of said facing walls whereby bulge resistance to flow of said material is enhanced and pressure of said material is distributed uniformly along said facing walls.
Claim 2
Dependent Claim
92 words
A multiple-cell box adapted for retention of material having cold-flow characteristics, said box comprising a plurality of independent paperboard cells having substantially coextensive facing walls, a flat substantially continuous paperboard reenforcing and securing sheet disposed between said walls, said paperboard sheet having opposed planar surfaces substantially coextensive with said facing walls, and adhesive bonding said planar surfaces to said facing walls over substantially the full extent of said facing walls whereby bulge resistance to flow of said material is enhanced and pressure of said material is distributed uniformly along said facing walls.
Claim 3
Dependent Claim
92 words
A multiple-cell box adapted for retention of material having cold-flow characteristics, said box comprising a plurality of independent paperboard cells having substantially coextensive facing walls, a flat substantially continuous paperboard reenforcing and securing sheet disposed between said walls, said paperboard sheet having opposed planar surfaces substantially coextensive with said facing walls, and adhesive bonding said planar surfaces to said facing walls over substantially the full extent of said facing walls whereby bulge resistance to flow of said material is enhanced and pressure of said material is distributed uniformly along said facing walls.
Claim 4
Dependent Claim
92 words
A multiple-cell box adapted for retention of material having cold-flow characteristics, said box comprising a plurality of independent paperboard cells having substantially coextensive facing walls, a flat substantially continuous paperboard reenforcing and securing sheet disposed between said walls, said paperboard sheet having opposed planar surfaces substantially coextensive with said facing walls, and adhesive bonding said planar surfaces to said facing walls over substantially the full extent of said facing walls whereby bulge resistance to flow of said material is enhanced and pressure of said material is distributed uniformly along said facing walls.
Claim 5
Dependent Claim
39 words
The multiple-cell box of claim 1 wherein a substantially continuous flat paperboard reenforcing sheet substantially coextensive with each end wall of the box is also adhesively bonded to such end wall over substantially the full extent of said wall.
Claim 6
Dependent Claim
46 words
The multiple-cell box of claim 1 wherein each of said facing walls is formed of a plurality of panels, the end edges of which are substantially in abutment to form a joint, and said joints of said facing walls are offset with respect to each other.
Claim 7
Dependent Claim
142 words
A multiple-cell box adapted for retention of material having cold-flow characteristics, said box comprising at least two independent paperboard cells each of rectangular shape in cross section and comprising three full wall panels and an end wall of a pair of panels which are substantially in abutment to form a joint, said jointed end walls being substantially coextensive and facing each other with the abutment joints offset with respect to each other, a flat substantially continuous paperboard reenforcing and securing pad disposed between said jointed walls, said paperboard pad having opposed rectangular planar surfaces substantially coextensive with said jointed walls, and adhesive bonding said pad planar surfaces to said jointed walls over substantially the full extent of said jointed walls whereby bulge resistance to flow of said material is enhanced and pressure of said material is distributed uniformly along said jointed walls.
Claim 8
Dependent Claim
142 words
A multiple-cell box adapted for retention of material having cold-flow characteristics, said box comprising at least two independent paperboard cells each of rectangular shape in cross section and comprising three full wall panels and an end wall of a pair of panels which are substantially in abutment to form a joint, said jointed end walls being substantially coextensive and facing each other with the abutment joints offset with respect to each other, a flat substantially continuous paperboard reenforcing and securing pad disposed between said jointed walls, said paperboard pad having opposed rectangular planar surfaces substantially coextensive with said jointed walls, and adhesive bonding said pad planar surfaces to said jointed walls over substantially the full extent of said jointed walls whereby bulge resistance to flow of said material is enhanced and pressure of said material is distributed uniformly along said jointed walls.
Claim 9
Dependent Claim
89 words
The multiple-cell box of claim 4 comprising a third independent paperboard cell of rectangular shape in cross section and comprising an end wall comprised of a pair of panels which are also substantially in abutment to form a joint, said jointed wall of said third cell being substantially coextensive with and facing a wall of one of said two cells, another paperboard reenforcing and securing pad between said jointed wall of said third cell and the wall facing the same, and adhesive bonding said pad to the latter walls.
Claim 10
Dependent Claim
30 words
The multiple-cell box of claim 5 wherein at least one paperboard reenforcing pad substantially coextensive with each end wall of the box is also adhesively bonded to such end wall.
