Claim 5

A multi-ply container having upright corners and comprising an inner ply, an intermediate ply and an outer ply adhesively bonded together, said inner ply being composed of a plurality of hingedly connected wall panels the end panels of which have upright facing edges unattached to each other, said intermediate ply covering said facing edges of said inner ply and having at at least one corner of the container upright edges which are unattached to each other, said outer ply including a plurality of wall panels integrally connected along an upright hinge connection line substantially in alignment with and covering a corner of the container, end edges of adjacent panels of said outer ply being unattached to each other at a corner of the container, and said container having at least two-ply thickness at each corner thereof.

Claim 6

A multi-ply container having upright corners and comprising an inner ply, an intermediate ply and an outer ply adhesively bonded together, said inner ply being composed of a plurality of hingedly connected wall panels the end panels of which have upright facing edges unattached to each other, said intermediate ply covering said facing edges of said inner ply and having at at least one corner of the container upright edges which are unattached to each other, said outer ply including a plurality of wall panels integrally connected along an upright hinge connection line substantially in alignment with and covering a corner of the container, end edges of adjacent panels of said outer ply being unattached to each other at a corner of the container, and said container having at least two-ply thickness at each corner thereof.

Claim 7

The container of claim 4 wherein said intermediate ply comprises a plurality of pads.

Claim 8

The container of claim 4 wherein said intermediate ply is a continuous strip of wall panels the end panels of which are the ones that have said unattached edges.

Claim 9

The container of claim 4 in which the plies are of paperboard, and at least two of said plies have their corrugations extending transversely with respect to each other.

Claim 10

The container of claim 4 wherein at least one of said plies has hingedly connected closure flaps to provide a closure for the container.

Claim 11

A multi-ply container composed of at least three plies adhesively bonded together and having upright walls and an upright corner construction of two-ply thickness provided by two of the plies, the remaining ply having adjacent end edges unattached to each other at said corner.

Claim 12

A multi-ply container composed of at least three plies adhesively bonded together and having upright walls and an upright corner construction of two-ply thickness provided by two of the plies, the remaining ply having adjacent end edges unattached to each other at said corner.

Claim 13

The construction of claim 9 wherein the inner of said plies has end edges substantially in abutment and unattached to each other.

Claim 14

A multi-ply container compRising at least three plies laminated together, a first one of which being an inner ply comprising panels hingedly connected together except at the edges of the end panels thereof, said edges being unattached and forming substantially an abutment joint, a second of said plies being an intermediate ply which covers said abutment joint, and a third of said plies being an outer ply comprising a plurality of pads with each pad having upright end edges and wall panels integrally connected along an upright hinge connection line positioned substantially in alignment with an upright corner of the container, the length of each pad being such that each end edge thereof is located at another corner of the container with a space between the end edges of adjacent pads, and a ply contiguous to said pads which form said outer ply comprising adjacent panels integrally connected along an upright hinge connection line closing each of said spaces between such pads.

Claim 15

A multi-ply container compRising at least three plies laminated together, a first one of which being an inner ply comprising panels hingedly connected together except at the edges of the end panels thereof, said edges being unattached and forming substantially an abutment joint, a second of said plies being an intermediate ply which covers said abutment joint, and a third of said plies being an outer ply comprising a plurality of pads with each pad having upright end edges and wall panels integrally connected along an upright hinge connection line positioned substantially in alignment with an upright corner of the container, the length of each pad being such that each end edge thereof is located at another corner of the container with a space between the end edges of adjacent pads, and a ply contiguous to said pads which form said outer ply comprising adjacent panels integrally connected along an upright hinge connection line closing each of said spaces between such pads.

Claim 16

The multi-ply container of claim 11 wherein said intermediate ply is also comprised of a plurality of said pads.

Claim 17

The multi-ply container of claim 11 wherein said joint of said inner ply is located between adjacent corners of the container.

Claim 18

The multi-ply container of claim 11 wherein said joint of said inner ply is located at a corner of the container.

Claim 19

The multi-ply container of claim 11 wherein said intermediate ply comprises panels hingedly connected together along integral hinge connection lines except the end panels the edges of which are unattached at a corner of the container.
