Abstract
Abstract A container for transporting bulk material either solid or liquid has a pallet and a sleeve having segments of its wall secured to the pallet and other segments of its wall folded inwardly to provide flaps. A tubular member having corrugated-paperboard or the like wall and a cross-section corresponding to that of the sleeve has one end thereof disposed in the sleeve and resting on the flaps. A plastic bag may be inserted in the container and is folded about its edges to overlap the flaps. A rigid disk such as a corrugated paperboard disk having a cross-section substantially equal to the cross-section of the sleeve is disposed in the bag adjacent its closed end with its peripheral edge under the flaps. When the bag is filled with material, it is expanded against the wall of the tubular member and the tubular member is pressed against the sleeve thereby securing the tubular member in the sleeve. A cup-shaped lid is slidably disposed over the open end of the tubular member to enclose the bag.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
161 words
A container comprising a pallet having a top and sides, a first wall member enclosing an elongated space having a polygonal cross-section, the lower ends of at least two segments of the said wall member extending downwardly along the sides of the pallet and secured thereto and the lower ends of at least two segments of the wall member being folded to form inwardly extending flaps disposed against the top of the pallet, a second wall member open at both ends and having a cross-section similar to that of the first wall member, one end of the second wall member being slidably disposed in the first member with its edge disposed on the said flaps and extending above the first member, said second wall member being adapted to expand under the weight of material contained therein and pressed into engagement with the first wall member, whereby the two said members are secured together solely by said expansion of the second member.
Claim 2
Dependent Claim
161 words
A container comprising a pallet having a top and sides, a first wall member enclosing an elongated space having a polygonal cross-section, the lower ends of at least two segments of the said wall member extending downwardly along the sides of the pallet and secured thereto and the lower ends of at least two segments of the wall member being folded to form inwardly extending flaps disposed against the top of the pallet, a second wall member open at both ends and having a cross-section similar to that of the first wall member, one end of the second wall member being slidably disposed in the first member with its edge disposed on the said flaps and extending above the first member, said second wall member being adapted to expand under the weight of material contained therein and pressed into engagement with the first wall member, whereby the two said members are secured together solely by said expansion of the second member.
Claim 3
Dependent Claim
55 words
The container of claim 1 comprising a flexible bag having a closed end adjacent to the pallet and a plate in the bag having a cross-section approximating that of the second wall member, said bag being disposed over and underneath the flaps, and said plate having its peripheral edge between the flaps and the pallet.
Claim 4
Dependent Claim
63 words
The container of claim 1 comprising a flexible bag in said second wall member, said bag having a closed end adjacent the top of the pallet, a plate in the bag, said being disposed over and underneath the flaps and over and underneath the periphery of the plate, and said plate has its periphery between the flaps and the top of the pallet.
