Abstract
Abstract A palletized container comprises a case of folded corrugated board with strengthened parallel feet extending beneath the case to enable the container to be lifted by a fork-lift vehicle. The feet are made from lengths of corrugated board folded into a rectangular configuration and rolled around tongues which are formed from the bottom flaps of the case, thereby interlocking the case and the feet without any need for stitching or gluing of the parts. The security of the container is achieved by the interleaving of the corrugated board pieces.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
126 words
A palletized container comprising a case formed from at least one piece of foldable packaging material, the case having two opposed ends each with a bottom flap, two opposed sides each with a bottom flap which is divided to define a foldable tongue at each end of each said flap, said tongues being located outside the bottom flaps of said opposed ends, and a separate pallet secured to the base of the case and comprising two parallel pallet supports defining a channel therebetween to receive the forks of a fork-lift vehicle, each pallet support comprising an elongate member folded over and around an opposed pair of said tongues to define a hollow tube encircling said tongues, and support means within said tubes to maintain their shape.
Claim 2
Dependent Claim
126 words
A palletized container comprising a case formed from at least one piece of foldable packaging material, the case having two opposed ends each with a bottom flap, two opposed sides each with a bottom flap which is divided to define a foldable tongue at each end of each said flap, said tongues being located outside the bottom flaps of said opposed ends, and a separate pallet secured to the base of the case and comprising two parallel pallet supports defining a channel therebetween to receive the forks of a fork-lift vehicle, each pallet support comprising an elongate member folded over and around an opposed pair of said tongues to define a hollow tube encircling said tongues, and support means within said tubes to maintain their shape.
Claim 3
Dependent Claim
48 words
A container as claimed in claim 1, in which each of said tongues is provided with a pair of parallel score lines across its width adjacent to the junction of the tongue with the case side to enable the outer pallet supports to be folded around the tongues.
Claim 4
Dependent Claim
31 words
A container as claimed in claim 2, in which the score lines are spaced by a distance substantially equal to twice the thickness of the material constituting the outer pallet supports.
Claim 5
Dependent Claim
27 words
A container as claimed in claim 2 wherein the pair of parallel score lines extend the full length of the material from which the case is assembled.
Claim 6
Dependent Claim
57 words
A container as claimed in claim 1, in which the bottom flaps of the case sides are slotted to the depth of the flaps at equal distances from each end of each flap to form said tongues, the width of the tongues being substantially equal to one dimension of the support means in the outer pallet supports.
Claim 7
Dependent Claim
16 words
A container as claimed in claim 1, in which said support means comprises struts of polystyrene.
Claim 8
Dependent Claim
54 words
A container as claimed in claim 1, in which each elongate member of said pallet supports comprises a length of corrugated board scored across the line of the corrugations on six lines whereby the elongate member when folded into a rectangular configuration provides a double thickness of board on two sides of the rectangle.
Claim 9
Dependent Claim
165 words
A palletized container comprising a case formed from at least one pace of foldable packaging material, the case having two opposed sides each with a bottom flap which is divided to define a foldable tongue at each end of said flap, a pallet secured to the base of the case and comprising two parallel pallet supports defining a channel therebetween to receive the forks of a fork-lift vehicle, each pallet support comprising an elongate member folded around an opposed pair of said tongues to define a hollow tube, support means within said tubes to maintain their shpae, a central pallet support between said outer pallet supports, said outer pallet supports each having a flap extending toward the central pallet support, said central pallet support comprising an elongate element folded to define a hollow tube with a pair of flaps extending one to each side of the hollow tube and interleafed between the bottom flaps of the case and said flaps of the outer pallet supports.
Claim 10
Dependent Claim
165 words
A palletized container comprising a case formed from at least one pace of foldable packaging material, the case having two opposed sides each with a bottom flap which is divided to define a foldable tongue at each end of said flap, a pallet secured to the base of the case and comprising two parallel pallet supports defining a channel therebetween to receive the forks of a fork-lift vehicle, each pallet support comprising an elongate member folded around an opposed pair of said tongues to define a hollow tube, support means within said tubes to maintain their shpae, a central pallet support between said outer pallet supports, said outer pallet supports each having a flap extending toward the central pallet support, said central pallet support comprising an elongate element folded to define a hollow tube with a pair of flaps extending one to each side of the hollow tube and interleafed between the bottom flaps of the case and said flaps of the outer pallet supports.
Claim 11
Dependent Claim
41 words
A container as claimed in claim 8, in which the free edges of the flaps of the central pallet support parallel to its fold lines abut respective edges of the bottom flaps of the case which are folded under said tongues.
