Abstract

The present disclosure is directed to a shipping container with a corrugated medium that lines an interior pocket of the shipping container as well devices and components (e.g., corrugating rollers, corrugating machines, scoring rollers, and scoring machines) that are utilized to manufacture the shipping containers. The corrugated medium has flutes that cushion, support, and protect a product that is shipped within the shipping container. The corrugated medium may include a first portion with first flutes and a second portion with second flutes that are offset relative to the first flutes. The offset first flutes and second flutes results in peaks of the first flutes nesting within valleys of the second flutes, and peaks of the second flutes nesting within valleys of the first flutes.

Claims (39)

1 . A recyclable shipping container, comprising:

a single face corrugated material that includes an outer liner layer and an inner corrugated layer, the inner corrugated layer including a plurality of flutes;

wherein the flutes extend across a first portion of the inner corrugated layer, such that the first portion of the inner corrugated layer is fluted, and do not extend across a second portion of the inner corrugated layer, such that the second portion of the inner corrugated layer is flat;

wherein the single face corrugated material is folded along a fold line that divides the corrugated material between a first panel and a second panel opposite to the first panel across the fold line.

2 . The recyclable shipping container of claim 1 , wherein the second portion of the inner corrugated layer extends along locations at which the corrugated material is configured to be cut to form individual portions of the corrugated material.

3 . The recyclable shipping container of claim 1 , wherein:

the first panel includes a first side edge portion that extends parallel to the flutes and a second side edge portion that extends parallel to the flutes;

the second panel includes a first side edge portion that extends parallel to the flutes and a second side edge portion that extends parallel to the flutes; and

the second portion of the inner corrugated layer extends along the first side edge portion of the second panel and along the first side edge portion of the second panel, such that the flutes are not present along the first side edge portion of the first panel and not present along the first side edge portion of the second panel.

4 . The recyclable shipping container of claim 3 , wherein:

the flutes do not extend across a third portion of the inner corrugated layer, such that the third portion of the inner corrugated layer is flat; and

the third portion of the inner corrugated layer extends along the second side edge portion of the first panel and extends along the second side edge portion of the second panel, such that the flutes are not present along the second side edge portion of the first panel and not present along the second side edge portion of the second panel.

5 . The recyclable shipping container of claim 1 , wherein the second portion of the inner corrugated layer extends parallel to the flutes.

6 . The recyclable shipping container of claim 1 , wherein the second portion of the inner corrugated layer extends along the fold line.

7 . The recyclable shipping container of claim 1 , wherein the second portion of the inner corrugated layer extends perpendicular to the flutes.

8 . A recyclable shipping container, comprising:

a single face corrugated material that includes an outer liner layer and an inner corrugated layer, the inner corrugated layer including a plurality of flutes;

wherein the flutes extend across a first portion of the inner corrugated layer, such that the first portion of the inner corrugated layer is fluted, and do not extend across a second portion of the inner corrugated layer, such that the second portion of the inner corrugated layer is flat; and

one or more score lines extend across the first portion of the inner corrugated layer, and the one or more score lines are configured to, in operation, provide conformability to the first portion of the inner corrugated layer;

wherein the single face corrugated material is folded along a fold line that divides the corrugated material between a first panel and a second panel opposite to the first panel across the fold line.

9 . The recyclable shipping container of claim 8 , wherein the second portion of the inner corrugated layer extends along locations at which the corrugated material is configured to be cut to form individual portions of the corrugated material.

10 . The recyclable shipping container of claim 8 , wherein:

the first panel includes a first edge portion that extends parallel to the flutes and a second side edge portion that extends parallel to the flutes;

the second panel includes a first side edge portion that extends parallel to the flutes and a second side edge portion that extends parallel to the flutes; and

the second portion of the inner corrugated layer extends along the first side edge portion of the second panel and along the second side edge portion of the second panel.

11 . The recycle shipping container of claim 8 , wherein the flutes do not extend across a third portion of the inner corrugated layer, such that the third portion of the inner corrugated layer is flat; and

the third portion of the inner corrugated layer extends along the second side edge portion of the first panel and along the second side edge portion of the second panel.

12 . The recyclable shipping container of claim 8 , wherein the second portion of the inner corrugated layer extends parallel to the flutes.

13 . The recyclable shipping container of claim 8 , wherein the second portion of the inner corrugated layer extends along the fold line.

14 . The recyclable shipping container of claim 8 , wherein the second portion of the inner corrugated layer extends perpendicular to the flutes.

15 . The recyclable shipping container of claim 8 , wherein the one or more score lines includes at least one first score line that is transverse to the flutes and extends across the flutes.

16 . The recyclable shipping container of claim 15 , wherein the one or more score lines includes at least one second score line that is transverse to the flutes, is transverse to the at least one first score line, and extends across the flutes.

17 . A recyclable shipping container, comprising:

a single face corrugated material that includes an outer liner layer and an inner corrugated layer, the single face corrugated material includes a first side edge and a second side edge opposite to the first side edge, and the inner corrugated layer includes a plurality of flutes;

wherein the flutes extend across a first portion of the inner corrugated layer between the first side edge and the second side edge, such that the first portion of the inner corrugated layer is fluted, and do not extend across a second portion of the inner corrugated layer at the first side edge and do not extend across a third portion of the inner corrugated layer at the second side edge, such that the second portion and the third portion of the inner corrugated layer are flat;

wherein the single face corrugated material is folded along a fold line at a fourth portion of the inner corrugated layer, the fold line and the fourth portion divides the corrugated material between a first panel and a second panel opposite to the first panel across the fold line and the fourth portion, and the fourth portion is flat.

18 . The recyclable shipping container of claim 17 , wherein the second portion is part of a first side wrap portion.

19 . The recyclable shipping container of claim 17 , wherein the third portion is part of a second side wrap portion.

20 . The recyclable shipping container of claim 17 , further comprising an adhesive on the second portion and the third portion.
