Abstract

A liner comprising a body portion and a flap portion. The body portion comprises a front, a back, a first side, a second side, and a bottom. The body portion defines a cavity. The flap portion is hingedly connected to a top end of the back of the body portion. The flap portion is sized to cover the cavity. The body portion and the flap portion comprise a single piece of insulative material.

First claim

That which is claimed is:

1. A liner configured for placement within a box, the liner comprising:
a single piece of insulative material; and
a corrugated cardboard panel adjacent to the single piece of insulative material, the corrugated cardboard panel defining a central body, a first bend line, a second bend line, and an end portion hingedly connected to the central body by the second bend line, the single piece of insulative material extending across a bend line defining a connection of a single liner flap portion with a liner body portion, the liner body portion comprising a plurality of sub-portions, the single piece of insulative material and the corrugated cardboard panel together reconfigurable between a flattened arrangement and an expanded arrangement, the corrugated cardboard panel extending beyond opposite ends of at least one of the sub-portions for providing structure to the sub-portions to at least partially define a memory retaining substantially block-shaped cavity in the expanded arrangement, the substantially block-shaped cavity defining an opening, the single liner flap portion covering an entirety of the opening of the substantially block-shaped cavity;
wherein the plurality of sub-portions comprises a bottom and a side, and wherein the liner body portion further comprises a pleat formed from excess liner body portion material gathered along the bottom proximate the side, the pleat configured to exert a spring force on the end portion of the corrugated cardboard panel to cause the end portion to rotate outwardly along the second bend line of the corrugated cardboard panel.

2. The liner of claim 1 , wherein the liner is recyclable.

3. The liner of claim 1 , wherein the insulative material comprises a paper-based material.

4. The liner of claim 1 , wherein the bend line is a first bend line, and wherein the plurality of sub-portions of the liner body portion further comprises a front, the single piece of insulative material extending across a second bend line defining connection of the front with the bottom of the liner body portion.

5. The liner of claim 4 , wherein the plurality of sub-portions of the liner body portion further comprises a back, the single piece of insulative material extending across a third bend line defining connection of the back of the liner body portion with the bottom of the liner body portion.

6. The liner of claim 1 , wherein the insulative material is a paper-based material.

7. The liner of claim 1 , wherein the liner flap portion and the bottom of the liner body portion are in substantially parallel planes upon the liner flap portion covering the cavity.

8. A packaging assembly comprising:
a box comprising a front, a back, a first side, a second side, a bottom, and a plurality of top flaps hingedly coupled to the front, the back, the first side, and the second side; and
a liner configured for placement within the box, the liner comprising:
a single piece of insulative material, and
a corrugated cardboard panel adjacent to the single piece of insulative material, the corrugated cardboard panel defining a central body, a first bend line, a second bend line, and an end portion hingedly connected to the central body by the second bend line, the single piece of insulative material extending across a bend line defining a connection of a single liner flap portion with a liner body portion, the liner body portion comprising a plurality of sub-portions, the corrugated cardboard panel extending beyond opposite ends of at least one of the sub-portions for providing structure to the sub-portions to at least partially define a memory retaining substantially block-shaped cavity, the substantially block-shaped cavity defining an opening, the single liner flap portion covering an entirety of the opening of the substantially block-shaped cavity;

wherein the plurality of sub-portions comprises a bottom and a side, and wherein the liner body portion further comprises a pleat formed from excess liner body portion material gathered along the bottom proximate the side, the pleat configured to exert a spring force on the end portion of the corrugated cardboard panel to cause the end portion to rotate outwardly along the second bend line of the corrugated cardboard panel.

9. The packaging assembly of claim 8 , wherein the liner is recyclable.

10. The packaging assembly of claim 8 , wherein the insulative material comprises a paper-based material.

11. The packaging assembly of claim 8 , wherein the side is a first side, and wherein the plurality of sub-portions of the liner body portion further comprises a front, a back, and a second side.

12. The packaging assembly of claim 8 , wherein the insulative material is a paper-based material.

13. The packaging assembly of claim 8 , wherein
the plurality of sub-portions of the liner body portion comprises a front and a bottom;
the single piece of insulative material and the panel together extend across a second bend line defining connection of the front of the liner body portion with the bottom of the liner body portion; and
the liner flap portion and the bottom of the liner body portion are in substantially parallel planes upon the liner flap portion covering the cavity.

14. A method of assembling a packaging assembly comprising the steps of:
providing a box comprising a front, a back, a first side, a second side, and a bottom;
providing a support comprising a corrugated cardboard material, the support defining a central body, a first support bend line, a second support bend line, and an end portion hingedly connected to the central body by the second support bend line, the first support bend line being perpendicular to the second support bend line;
providing a liner comprising:
a single piece of insulative material; and
a panel coupled to the single piece of insulative material and adjacent to the support, the panel comprising a fiber-based material, the single piece of insulative material and the panel defining a plurality of bend lines, the single piece of insulative material and the panel together extending across at least two bend lines, the liner comprising a plurality of sub-portions, the plurality of sub-portions comprising a bottom of the liner and a pleat proximate the bottom, the pleat creating a region of excess material along a portion of the bottom, the panel extending beyond opposite ends of at least one of the sub-portions for providing structure to the sub-portions to at least partially define a memory retaining substantially block-shaped cavity, the substantially block-shaped cavity defining an opening;

providing a single lid sized to cover an entirety of the opening of the substantially block-shaped cavity;
inserting the liner and the support within the box so that the liner is adjacent to the front of the box, the back of the box, the first side of the box, and the second side of the box, so that the pleat exerts a spring force on the end portion of the support to cause the end portion to rotate outwardly along the second support bend line, and so that the support is adjacent to the bottom of the box, while the sub-portions of the liner maintain a shape of the substantially block-shaped cavity; and
positioning the single lid over the substantially block-shaped cavity to cover the entirety of the opening.

15. The method of assembling a packaging assembly of claim 14 , wherein the liner is recyclable.

16. The method of assembling a packaging assembly of claim 14 , wherein the insulative material comprises a paper-based material.

17. The method of claim 14 , wherein the plurality
