Abstract

A shipping container made of two panels each made of recyclable, single face corrugated paper comprising an outer liner with corrugated medium. In one embodiment, the panels are formed from a large blank that is folded in half and joined at their side edges. The flutes on the corrugated mediums are parallel and longitudinally aligned with the shipping container's longitudinal axis. The top edge of each panel is detached and form a top opening into an interior pocket formed between the two panels. Formed or attach to one panel is a top flap configured to be folded over and selectively attached to the opposite panel to close the top opening. Formed on each corrugated medium is at least one set of score lines of various geometric shapes and orientations. The score lines act as folding lines that enable the panels to bend along different axes so that the overall shape of the shipping container better conforms to the object placed in the interior pocket. The sizes of flutes on each panel may be the same size or vary in size. The flutes on opposite panels may be axially aligned or offset. Improved side edges attachment features are provided that reduce side edge separation and reduce thickness.

Claims (34)

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 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;

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;

wherein 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 panel includes an external surface;

wherein the first panel includes a main body and a first side wrap extension coupled to the main body at the first side edge portion of the first panel, the first side wrap extension includes a first free end edge at which the first side wrap extension terminates;

wherein the flutes extend across the main body of the first panel and do not extend across the first side wrap extension of the first panel from the first side edge portion to the first free end edge; and

wherein the first side wrap extension of the first panel extends around the first side edge portion of the second panel to couple the first free end edge of the first side wrap extension of the first panel to the external surface of the second panel in close proximity to the first side edge portion of the second panel.

2 . The recyclable shipping container of claim 1 wherein the first side wrap extension of the first panel is coupled to the external surface of the second panel in close proximity to the first side edge portion of the second panel by an adhesive.

3 . The recyclable shipping container of claim 1 wherein the first panel includes a second side wrap extension coupled to the main body at the second side edge portion of the first panel, the second side wrap extension includes a second free end edge at which the second side wrap extension terminates;

wherein the flutes do not extend across the second side wrap extension of the first panel from the second side edge portion of the first panel to the second free end edge of the second side wrap extension;

wherein the second side wrap extension of the first panel extends around the second side edge portion of the second panel, to couple the second free end edge of the second side wrap extension of the first panel to the external surface of the second panel in close proximity to the second side edge portion of the second panel.

4 . The recyclable shipping container of claim 3 wherein the second side wrap extension of the first panel is coupled to the external surface of the second panel by an adhesive.

5 . The recyclable shipping container of claim 1 wherein the second panel includes a main body a second side wrap extension coupled to the main body at the second side edge portion of the second panel, the second side wrap extension includes a second free end edge at which the second side wrap extension terminates;

wherein the flutes extend across the main body of the second panel and do not extend across the second side wrap extension of the second panel from the second side edge portion to the second free end edge;

wherein the second side wrap extension of the second panel extends around the second side edge portion of the first panel, to couple the second side edge portion of the second panel to the second side edge portion of the first panel.

6 . The recyclable shipping container of claim 5 wherein the second side wrap extension of the second panel is coupled to the first panel by an adhesive.

7 . 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 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;

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;

wherein 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;

wherein the first panel includes a main body and a first side extension coupled to the main body at the first side edge portion of the first panel;

wherein the flutes extend across the main body of the first panel and do not extend across the first side extension of the first panel;

wherein the first side extension of the first panel is coupled to the first side edge portion of the second panel, and the flutes are not present at a region of the second panel at which the first side extension is coupled to the second panel.

8 . The recyclable shipping container of claim 7 wherein the first side extension of the first panel is coupled to the first side edge portion of the second panel by an adhesive.

9 . The recyclable shipping container of claim 7 wherein the first panel includes a second side extension coupled to the main body at the second side edge portion of the first panel;

wherein the flutes do not extend across the second side extension of the first panel;

wherein the second side extension of the first panel is coupled to the second side edge portion of the second panel.

10 . The recyclable shipping container of claim 8 wherein the second side extension of the first panel is coupled to the second side edge portion of the second panel by an adhesive.

11 . The recyclable shipping container of claim 7 wherein the second panel includes a main body and a first side extension coupled to the main body at the second side edge portion of the second panel;

wherein the flutes extend across the main body of the second panel and do not extend across the first side extension of the second panel;

wherein the first side extension of the second panel is coupled to the second side edge portion of the first panel.

12 . The recyclable shipping container of claim 11 wherein the first side extension of the second panel is coupled to the first panel by an adhesive.
