Claim 6

Dependent Claim 166 words

A combination pallet/bulk path container comprising, a pallet, a first end cap positioned on said pallet, a body portion for said bulk pack the lower end of which is inserted in said first end cap and a second end cap placed over the upper end of said bulk pack body portion, the improvement wherein said body portion is prepared as a pre-banded unit from a pair of precut and scored wall forming blanks of paperboard, said blanks being unsecured with respect to one another and having coterminous upper and lower edges and unsecured ends, said blanks being scored to provide at least four panels, said blanks being folded and interleaved together with like panels overlapping one another to produce a construction wherein the ends of each respective blank substantially abut one another but are spaced apart by a corner of the other respective blank, said walls being pre-banded so that the pre-applied bands may restrain the walls from bulging outwardly when the body portion is filled.

Claim 7

Dependent Claim 166 words

A combination pallet/bulk path container comprising, a pallet, a first end cap positioned on said pallet, a body portion for said bulk pack the lower end of which is inserted in said first end cap and a second end cap placed over the upper end of said bulk pack body portion, the improvement wherein said body portion is prepared as a pre-banded unit from a pair of precut and scored wall forming blanks of paperboard, said blanks being unsecured with respect to one another and having coterminous upper and lower edges and unsecured ends, said blanks being scored to provide at least four panels, said blanks being folded and interleaved together with like panels overlapping one another to produce a construction wherein the ends of each respective blank substantially abut one another but are spaced apart by a corner of the other respective blank, said walls being pre-banded so that the pre-applied bands may restrain the walls from bulging outwardly when the body portion is filled.

Claim 8

Independent Claim 158 words

A method of forming the body portion of a bulk bin container comprising: (a) providing a pair of generally rectangular flat blanks each scored along spaced parallel score lines to provide first and second side walls and first and second end walls; (b) combining each of said flat blanks such that a first side wall and end wall of one blank is superimposed over a first side wall and end wall of the other blank with the ends of said blanks extending beyond said superimposed portions; (c) folding and interleaving the ends of said blanks comprising the second side walls and end walls into superimposed position to produce a construction wherein the unsecured ends of each respective blank are separated from one another by a corner of the other respective blank; and, (d) pre-banding said folded and interleaved blanks in the knocked down condition to form a substantially flat, collapsed body portion that is readily squared for use.

Claim 9
