FOUR-PIECE NESTABLE COOLER

Description

TECHNICAL FIELD

The present disclosure relates to insulated shipping containers, and more particularly to insulated shipping containers assembled from component pieces.

BACKGROUND

Merchants conventionally ship perishable products in insulated containers to maintain a desired temperature for the products, to protect the products, and/or to prevent the contents from spoiling during shipping. A foam cooler within a cardboard box is an effective option for an insulated shipping container. However, storing traditional two-piece foam coolers comprising a five-sided cooler piece (bottom and four side walls) and a lid piece results in increased volume requirement for shipping and storing the two-piece coolers prior to use. Accordingly, a foam cooler comprising component pieces that may be assembled to form the cooler provides for more efficient storage because the pieces may be stacked. However, coolers that are capable of being assembled may be confusing to assemble rapidly when the pieces are of differing sizes or there are too many pieces to assemble.

SUMMARY

Techniques herein provide an insulated shipping container comprising a cardboard box housing a four-piece cooler that is assembled from two identical interlocking L-shaped pieces that form the side walls of the cooler, a bottom piece for the cooler, and a top lid piece for the cooler that is identical to the bottom piece. In an example, the cooler comprises a foam cooler assembled from two L-shaped foam pieces and two top/bottom foam pieces. An example L-shaped piece comprises a portion of a cooler comprising two adjacent, perpendicular faces of a cooler comprising a joined corner, a first edge comprising an indention, and a second edge comprising a protrusion. In another example, the first and second edges comprises flat edges. In this example, two L-shaped pieces may be joined by connecting a first edge of a first L-shaped piece with a second edge of a second L-shaped piece and also connecting a second edge of the first L-shaped piece with a first edge of the second L-shaped piece. In an example, the first edge of the first L-shaped piece is joined to the second edge of the second L-shaped piece at a first corner and the second edge of the first L-shaped piece is joined to the first edge of the second L-shaped piece at a second corner opposite the first corner, the two connected L-shaped pieces forming four adjacent sides of a right rectangular prism with an open top side and an open bottom side, the open top face and the open bottom face comprising the same dimensions. In another example, the first edge of the first L-shaped piece is joined to the second edge of the second L-shaped piece within a first face and the second edge of the first L-shaped piece is joined to the first edge of the second L-shaped piece within a second face opposite the first face, the two connected L-shaped pieces forming four adjacent sides of a right rectangular prism with an open top side and an open bottom side, the open top face and the open bottom face comprising the same dimensions. In an example, the right rectangular prism comprises a cube. In an example, a top/bottom piece comprises dimensions including the open bottom face of the connected two identical L-shaped pieces plus the width of the four edges circumscribing the open bottom face of the connected two identical L-shaped pieces.

In an example, a merchant assembles two identical top/bottom pieces and two identical L-shaped pieces to form a cooler within a cardboard box, the cardboard box comprising a right rectangular prism comprising dimensions equal to or greater than the dimensions of the cooler such that the cardboard box may house the cooler. In an example, a merchant prepares an insulated shipping container by resting a first top/bottom piece in the bottom of the open cardboard box. Next, the merchant may connect two identical L-shaped pieces by joining the first edge of the first L-shaped piece is joined to the second edge of the second L-shaped piece and the second edge of the first L-shaped piece is joined to the first edge of the second L-shaped piece, the two connected L-shaped pieces forming four adjacent sides of a right rectangular prism with an open top side and an open bottom side having the same dimensions as the open top side. The merchant may place the connected two identical L-shaped pieces forming the four adjacent sides on top of the first top/bottom piece such that either the open bottom side or the open top side of the connected L-shaped pieces is perpendicular to the top/bottom piece resting at the bottom of the box. The merchant may place one or more perishable products resting on top of the top/bottom piece within the four adjacent sides of the assembled two identical L-shaped pieces. The merchant may place a second top/bottom piece on top of the remaining open side of the right rectangular prism formed by the connected two identical L-shaped pieces that are resting on top of the first top/bottom piece, the second top/bottom piece comprising the same dimensions as the first top/bottom piece. In this example, the merchant forms an insulated shipping container comprising one or more perishable products, the insulated shipping container comprising a cardboard box comprising a cooler comprising the two connected identical L-shaped pieces and the two identical top/bottom pieces covering the open faces resulting from the joining of the two identical L-shaped pieces. The merchant may close the cardboard box to secure the assembled cooler comprising the one or more perishable products and ship the cardboard box to a desired destination.

These and other aspects, objects, features, and advantages of the example embodiments will become apparent to those having ordinary skill in the art upon consideration of the following detailed description of illustrated example embodiments.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS
Overview

The example embodiments described herein provide a description of an insulated shipping container comprising a cardboard box, two identical L-shaped pieces, and two identical top-bottom pieces and a process for packing an insulated shipping container. Current applications for insulated containers do not provide for a four-piece cooler packable within a cardboard box that is assembled from two identical interlocking L-shaped pieces that form the side walls of the cooler, a bottom piece for the cooler, and a top lid piece for the cooler that is identical to the bottom piece.

In an example, an insulated shipping container comprises a cardboard box housing a four-piece cooler that is assembled from two identical interlocking L-shaped pieces that form the side walls of the cooler, a bottom piece for the cooler, and a top piece for the cooler that is identical to the bottom piece. A merchant assembles the four-piece cooler within the cardboard box with one or more perishable items within the cooler. The merchant may seal the cardboard box with the four-piece cooler within to produce the insulated shipping container. The merchant may ship the insulated shipping container to an address of a customer that ordered the one or more perishable items from the merchant.

An example insulated shipping computer is comprised of two identical L-shaped pieces, two identical top-bottom pieces, and a cardboard box. An example L-shaped piece comprises a portion of a cooler comprising two adjacent, perpendicular faces of a cooler comprising a joined corner, a first edge comprising an indention, and a second edge comprising a protrusion. In this example, the protrusion inversely corresponds to the indention such that two L-shaped pieces may interlock or otherwise align at a first junction comprising the interlocking or aligning of a protruding edge of a first L-shaped piece with an indention edge of a second L-shaped piece and at a second junction comprising the interlocking or aligning of an indention edge of the first L-shaped piece with a protruding edge of the second L-shaped piece. In an example, identical L-shaped pieces each comprise eight faces, wherein all faces of each L-shaped piece are either oriented parallel or perpendicular to all other faces.

In an example, a protruding edge of a first L-shaped piece interlocks with an indention edge of a second L-shaped piece via a lock-and-key junction, similarly to two pieces of a puzzle. In this example, two L-shaped pieces may be joined by connecting a first edge of a first L-shaped piece with a second edge of a second L-shaped piece at a first junction and also connecting a second edge of the first L-shaped piece with a first edge of the second L-shaped piece at a second junction. In an example, the first edge of the first L-shaped piece is joined to the second edge of the second L-shaped piece at a first corner and the second edge of the first L-shaped piece is joined to the first edge of the second L-shaped piece at a second corner opposite the first corner, the two connected L-shaped pieces forming four adjacent sides of a right rectangular prism with an open top side and an open bottom side, the open top face and the open bottom face comprising the same dimensions. In another example, the first edge of the first L-shaped piece is joined to the second edge of the second L-shaped piece within a first face and the second edge of the first L-shaped piece is joined to the first edge of the second L-shaped piece within a second face opposite the first face, the two connected L-shaped pieces forming four adjacent sides of a right rectangular prism with an open top side and an open bottom side, the open top face and the open bottom face comprising the same dimensions. In an example, the right rectangular prism comprises a cube. In an example, a top/bottom foam piece comprises dimensions including the open bottom face of the connected two identical L-shaped pieces plus the width of the four edges circumscribing the open bottom face of the connected two identical L-shaped pieces.

In an example, a merchant assembles two identical top/bottom foam pieces and two identical L-shaped pieces to form a cooler within a cardboard box, the cardboard box comprising a right rectangular prism comprising dimensions equal to or greater than the dimensions of the cooler such that the cardboard box may house the cooler. In an example, a merchant prepares an insulated shipping container by resting a first top/bottom foam piece in the bottom of the open cardboard box. Next, the merchant may connect two identical L-shaped pieces by joining the first edge of the first L-shaped piece is joined to the second edge of the second L-shaped piece and the second edge of the first L-shaped piece is joined to the first edge of the second L-shaped piece, the two connected L-shaped pieces forming four adjacent sides of a right rectangular prism with an open top side and an open bottom side having the same dimensions as the open top side. The merchant may place the connected two identical L-shaped pieces forming the four adjacent sides on top of the first top/bottom foam piece such that either the open bottom side or the open top side of the connected L-shaped pieces is perpendicular to the top/bottom foam piece resting at the bottom of the box.

The merchant may place one or more perishable products resting on top of the top/bottom foam piece within the four adjacent sides of the assembled two identical L-shaped pieces. The merchant may place a second top/bottom foam piece on top of the remaining open side of the right rectangular prism formed by the connected two identical L-shaped foam pieces that are resting on top of the first top/bottom foam piece, the second top/bottom foam piece comprising the same dimensions as the first top/bottom foam piece. In this example, the merchant forms an insulated shipping container comprising one or more perishable products, the insulated shipping container comprising a cardboard box comprising a cooler comprising the two connected identical L-shaped foam pieces and the two identical top/bottom foam pieces covering the open faces resulting from the joining of the two identical L-shaped foam pieces. The merchant may close the cardboard box to secure the assembled cooler comprising the one or more perishable products and ship the cardboard box to a desired destination.

By using and relying on the methods and systems described herein, the merchant may create and pack an insulated shipping container comprising a cardboard box, two identical L-shaped foam pieces, and two identical top-bottom foam pieces and a process for packing an insulated shipping container. As such, the systems and methods described herein may reduce the storage space necessary for storage of components of insulated shipping containers and increase the ease at which insulated shipping containers may be assembled. For example, the L-shaped pieces may be stacked and efficiently stored according to the example embodiments provided herein. Further, the L-shaped ideas, being identical, are easily assembled by merchant agents by locking or otherwise aligning two L-shaped pieces along interlocking or inverse flat edges.
