Shipping container and packaging cushion assembly

Abstract

A shipping assembly is described. The assembly includes a shipping container, a bottom structure, and a top structure. The bottom and top structures retain objects in a spaced-apart arrangement within the shipping container. A paperboard sheet is folded into three horizontal layers to form the bottom structure. A first layer has apertures to retain the objects. A second layer is below and spaced apart from the first layer with a substantially flat surface below the first apertures. A third layer is below and spaced apart from the second layer. Another paperboard sheet is folded into two horizontal layers to form the top structure. A fourth layer has another set of apertures to retain the objects. A fifth layer is above and spaced apart from the fourth layer. The apertures are align to position the objects in the shipping container.

Description

BACKGROUND

Shipping containers and packaging cushions can be employed in logistics transportation and package shipment as an assembly to contain objects. Some of the objects can be broken as the shipping container travels through a distribution channel. Existing packages are often designed for bulk retail distribution on pallets, and as such lack sufficient shock and vibration absorption or packaging cushions to protect non-palletized shipments of fragile goods. Other options include engineered protective packaging cushions, such as formed foam bottle carriers. However, engineered packaging cushions are generally tailored to specific product shapes and requires expensive tooling to produce.

The top structure includes a fifth horizontal layer above and spaced apart from the fourth horizontal layer. The top structure includes third sidewalls coupling the fourth horizontal layer to the third horizontal layer. The third sidewalls are sized to maintain the fourth horizontal layer spaced apart from the fifth horizontal layer.

Further implementations of the present disclosure include packaging for a shipping container. The packaging for a shipping container includes a first paperboard sheet and a second paperboard sheet.

The first paperboard sheet includes a first region, a pair of first sidewall regions, a pair of second regions, a pair of second sidewall regions, a pair of third regions, and a pair of third sidewall regions.

The first region includes multiple of first apertures. Each of the first sidewall regions are coupled to an opposite side of the first region and separated therefrom by a first set of perforations. Each of the second regions are coupled to different ones of the first sidewall regions and separated therefrom by a second set of perforations. Each of the second sidewall regions are coupled to different ones of the second regions and separated therefrom by a third set of perforations. Each of the third regions are coupled to different ones of the second sidewall regions and separated therefrom by a fourth set of perforations. Each of the third sidewall regions are coupled to different ones of the third regions and separated therefrom by a fifth set of perforations.

The second paperboard sheet is folded into a top structure for the objects. The second paperboard sheet includes a fourth region, a pair of fourth sidewall regions, a pair of fifth regions, and a pair of fifth sidewall regions.

In some implementations, the fifth sidewall regions include retaining tab structures formed at each of the third common edge and the fourth common edge.

Particular implementations of the subject matter described in this specification can be implemented so as to realize one or more of the following advantages and address the shortcomings of existing product packaging.

Implementations provide a shipping assembly that uses environmental friendly, recyclable, and sustainable materials to economically ship fragile consumer goods directly to consumers. For example, implementations of the present disclosure can be made from recyclable paperboard for lightweight items or corrugated board for heavyweight items. In addition, implementations can be unfolded and reused for different size/shape objects. Implementations provide sufficient shock and vibration absorption or packaging cushion to prevent or minimize damage during transit. For example, implementations are configured to include shock absorbing zones and/or retain objects in a fixed position spaced away from each other and from the sides of a shipping box where the objects could be impacted if the box is mishandled. Implementations can also be manufactured at significantly lower cost than current engineered packaging cushion solutions. For example, implementations of shipping assemblies disclosed herein do not require expensive upfront-tooling setups required for engineered solutions. Instead, implementations can be formed simply press cutting and perforating flat sheets paperboard or corrugated board. In addition, implementations of the packaging can be stored and shipped as flat sheets, thereby, making more efficient use of storage and shipping space for the shipping assembly components themselves. Because the shipping assemblies are formed from flat paperboard, or corrugated board, the apertures used to secure objects can be cut to various sizes to accommodate many different size/shaped objects without the need to retool a manufacturing line and/or replace molding dies.

The details of one or more implementations of the subject matter described in this specification are set forth in the accompanying drawings and the description below. Other features, aspects, and advantages of the subject matter will become apparent from the description, the drawings, and the claims.

DETAILED DESCRIPTION

A distribution channel for sending and receiving shipments generally employs shipping containers and packaging cushions to protect the shipped objects. The objects can include breakable objects. Breakable objects can crack, fracture, or shatter when a threshold force or repetitive threshold force is transmitted to the breakable object. The breakable objects can be glass. Some breakable objects can be filled with liquid. When the threshold force or the repetitive threshold force breakable object cracks, fractures, or shatters, the breakable object cracks, fractures, or shatters and the contents (e.g., liquid, powder, gas) can flow out of the breakable object and contaminate other breakable objects. Additionally, pieces of broken objects or the contents of the broken objects can harm the user.

While most shipping containers for breakable objects are made of recyclable corrugated boards, some of the traditional shipping containers for breakable objects are made of plastic or wood which make recycling shipping containers difficult and costly. If not recycled, those plastic or wood shipping containers may be sent to land-fills directly, end up at land-fills, or are dumped into the ocean where they remain and do not be decomposed, polluting the land or ocean. Additionally, these plastic materials may contaminate water and/or injure fish or other marine animals.

The present disclosure describes a shipping assembly (e.g., packaging) that can be made from flat sheets of paperboard or corrugated board. The paperboard or corrugated board is cut and perforated according to unique patters that permit it to be folded into top and bottom cushion support structures that provide shock absorption for breakable objects placed in a shipping container.

FIG. 1 illustrates a perspective view of an exemplary shipping assembly 100. The shipping assembly 100 includes a shipping container 102, a bottom cushion support structure 112, and a top cushion support structure 114. One or more objects 110a-110f can be placed in the shipping container 102 for shipment.

The shipping container 102 can be a box. The shipping container 102 is defined by six surfaces. A first surface (not shown) is a bottom to the box. A second surface 104a, a third surface 104b, a fourth surface 104c, and a fifth surface 104d define the sides of the box. A top surface 106 of the shipping container is defined by four top panels 108a-108d which fold together to create the top surface. Two or more of the top panels 108a-108d are fastened together to seal the shipping container 102 shut. For example, top panels 108a and 108c can be folded toward an interior of the shipping container 102 and then the top panels 108b and 108d can be folded toward each other and taped together with a packing tape (not shown) by the user.

The shipping container 102 can be rectangular (as shown). Alternatively, the shipping container 102 can be square, triangular, or circular. The shipping container 102 can be paperboard, corrugated board. The corrugated board can be single walled or double walled. The corrugated board can be paper or plastic.

The shipping assembly 100 includes the bottom cushion support structure 112 and the top cushion support structure 114. The cushion support structures 112, 114 retain the objects 110a-110f in a spaced-apart arrangement within the shipping container 102 and provides shock absorption for the objects 110a-110f.

FIG. 2A is a top view an example unfolded bottom cushion support structure 112 of FIG. 1 and FIG. 2B is a side view an example folded bottom cushion support structure of FIG. 1. The unfolded bottom cushion support structure 112 is a paperboard sheet 202 which can be folded to form a folded bottom cushion support structure 112 (e.g., as shown in FIGS. 2C-2G). Alternatively, the paperboard sheet 202 can be a corrugated board sheet. The sheet 202 is formed into multiple regions 206, 228a, 228b, 226a, 226b, 230a, 230b, 218a, 218b, 230c, and 230d each separated by perforations 244. The regions, when folded at the perforations 244, form multiple layers (e.g., first or top layer 206, second or middle layer 212, and third or bottom layer 220). The center region forms the first or top layer 206. The top layer 206 includes multiple apertures 208. A pair of sidewall regions 228a, 228b border the center region (e.g., layer 206) on opposite sides. When folded, the sidewall regions 228a, 228b will form outer sidewalls 228 of the bottom cushion support structure 112. A pair of second regions 226a, 226b border each of the two sidewall regions 228a, 228b. When folded, the second regions 226a, 226b will form the bottom layer 220 of the bottom cushion support structure 112. A second pair of sidewall regions 230a, 230b border the second regions 226a, 226b. When folded, the second pair of sidewall regions 230a, 230b will from a first set of sidewalls 228 that support the middle layer 212 and separate the middle layer 212 from the bottom layer 220. A pair of third regions 218a, 218b, border the second set of sidewall regions 230a, 230b. When folded the third pair of regions 218a, 218b will form the middle layer 212 of the support structure. A third pair of sidewall regions 230c, 230d border the third regions 218a, 218b. When folded the third pair of sidewall regions will form a second set of sidewalls 228 that support the middle layer 212 and separate the middle layer 212 from the bottom layer 220.

In some implementations, one or both of the second and third pairs of sidewall regions 230a-230d can include support tabs 236. The support tabs 236 are sized such that when the bottom cushion support structure is folded, the support tabs 236 provide additional structural support to the bottom of the top layer 206. As shown in FIG. 2B, the support tabs 236 extend between the middle layer 212 and the top layer 206 and act as pillars to support the top layer 206 above the middle layer 212.

In some implementations, the second pair of sidewall regions 230a, 230b can include interlocking tabs 234a-234d. The interlocking tabs 234a-234d can be used to retain the bottom cushion support structure 112 in the folded configuration, e.g., as shown in FIGS. 2B and 2G.

FIGS. 2C-2G illustrate the steps of folding the bottom cushion support structure 112 of FIG. 1. The first paperboard sheet 202 is folded to form a first set of layers 206, 212, 220. The first set of layers 206, 212, 220 includes a first horizontal layer 206. The horizontal layer 206 includes multiple first apertures 208. Each of the first apertures 208 are sized to retain first ends 210a-210f of each of the shipping objects 110a-110f, respectively.

Each of the first apertures 208 can be the shape of a circle (e.g., as shown in FIG. 2A), a square, or a rectangle. Each of the first apertures 208 can be the same shape. Alternatively, one or more of first apertures 208 can be different shapes. Each of the first apertures 208 are sized to form a friction fit with the respective first ends 210a-210f of the shipping objects 110a-110f.

The first set of layers 206, 212, 220 includes a second horizontal layer 212. The second horizontal layer 212 is below the first horizontal layer 206. The second horizontal layer 212 is spaced apart from the first horizontal layer 206 by a height 216. The second horizontal layer 212 serves as a floor upon which the objects 110 sit when place in the apertures 208 of the bottom cushion support structure 112. The second horizontal layer 212 is a substantially flat surface below the multiple first apertures 208. The second horizontal layer 212 is formed by a pair of second regions 218a and 218b.

The first set of layers 206, 212, 220 includes a third horizontal layer 220. The third horizontal layer 220 is below the second horizontal layer 212. The third horizontal layer 220 is spaced apart from the second horizontal layer 212 by a distance 224. This distance 224 provides separation between the objects 110 and the outer packaging of a shipping box in which the objects 110 are contained. The distance 224 between layers 212 and 220 also absorbs shock and provides some protection for the objects 110 against impact to the shipping container 102. The third horizontal layer 220 is a substantially flat surface below the second horizontal layer 212. The third horizontal layer 220 is formed by a pair of third regions 226a and 226b.

The bottom cushion support structure 112 includes sidewalls coupling each of the three horizontal layers 206, 212, and 220. For instance, a first set of sidewalls 228 couple the first horizontal layer 206 to the third horizontal layer 220. A second set of sidewalls 230 couple each of the pair of the third regions 226a and 226b which make up the third horizontal layer 220 to each of the pair of second regions 218a and 218b which make up the second horizontal layer 212.

A height 232 of the first sidewalls 228 is greater than the height 224. The height 224 also corresponds to the height of the second sidewalls 230. In the illustrated example, the first sidewalls 228 are sized to maintain the first horizontal layer 206 spaced apart from the third horizontal layer 220 and from the second horizontal layer 212. The second sidewalls 230 are sized to maintain the second horizontal layer 212 spaced apart from the third horizontal layer 220.

Bottom cushion support structure 112 includes a first retaining tab 234a on one of the second sidewalls 230. The first retaining tab 234a creates a friction fit with the opposing/adjoining other second sidewall 230 to retain the bottom cushion support structure 112 in a folded form. The first retaining tab 234a can engage a second retaining tab 234b on the other second sidewall 230, substantially similar to the first retaining tab 234a to create the friction fit. The first retaining tab 234a and the second retaining tab 234b form a pair of retaining tabs. Another pair of retaining tabs 234c and 234d can be positioned on an opposite side of the second sidewalls 230 to create another friction fit to retain the bottom cushion support structure 112 in the folded form.

The second sidewalls 230 can include two pair of sidewalls 230 supporting and extending between the second horizontal layer 212 and the third horizontal layer 220. One pair of sidewalls 230 are located at opposite outer edges (e.g., 238a, 238b shown in FIG. 2A, respectively, of the second horizontal layer 212. The other pair of sidewalls 230 are located approximately midway between the first pair of sidewalls 230. This second pair of sidewalls 230 are adjacent to each other, when the bottom cushion support structure 112 is in a folded configuration, and can include retaining tabs 234a-234d.

The second pair of sidewalls 230 can include the pair of retaining tabs 234c and 234d previously described. The pair of retaining tabs 234c and 234d are positioned on an opposite side of the second sidewalls 230 from the sidewalls 230 to create another friction fit to retain the bottom cushion support structure 112 in the folded form.

In some cases, each sidewall 230 of both the first pair and the second pair of sidewalls 230 include at least one of support tabs 236 extending between the second horizontal layer 212 and the first horizontal layer 206.

Bottom cushion support structure 112 includes support tabs 236. In some examples, the support tabs 236 are coupled to and extend from one of the pair of second regions 218a which make up the second horizontal layer 212. The support tabs 236 are coupled to and extend from the other of the pair of second regions 218b which make up the second horizontal layer 212. In some examples, the support tabs 236 are coupled to and extend from the sidewall regions (e.g., 230a-230d shown in FIG. 2A) that form the second sidewalls 230. In either example, the support tabs 236 extend between the second horizontal layer 212 and the first horizontal layer 206. The support tabs 236 support and space the first horizontal layer 206 from the second horizontal layer 212. The height of at least one of the support tabs 236, which is the same as height 216, can be substantially the same as a distance by which the second horizontal layer 212 is spaced apart from the first horizontal layer 206.

Each of the portions of the bottom cushion support structure 112 (the first horizontal layer 206, the first sidewalls 228, the pair of the third regions 226a and 226b, the second sidewalls 230, the pair of second regions 218a and 218b, and the second pair of sidewalls 230) have two common edges 246a and 246b. Referring to FIG. 2A, each of the regions of the bottom cushion support structure 112 are separated from each other by perforations 244. The regions of the unfolded bottom cushion support structure 112 are folded along the perforations 244 to form the folded bottom cushion support structure 112. The perforations 244 extend from the common edge 246a to the common edge 246b.

Referring to FIG. 1, the shipping assembly 100 includes the top cushion support structure 114. The top cushion support structure 114 retains the one or more shipping objects 110a-110f in a spaced-apart arrangement within the shipping container 102. The top cushion support structure 114 is generally similar to the bottom cushion support structure 112 previously described.

FIG. 3A is a top view an example unfolded top cushion support structure 114 of FIG. 1 and FIG. 3B is a side view an example folded top cushion support structure 114 of FIG. 1. The unfolded top cushion support structure 114 is a paperboard sheet 200 which can be folded to form a folded top cushion support structure 114 (e.g., as shown in FIGS. 3C-3G). The paperboard sheet 200 can be a corrugated board sheet. The sheet 200 is formed into multiple regions 304, 322a, 322b, 320a, 320b, 322c, and 322d each separated by perforations 326. The regions, when folded at the perforations 326, form multiple layers (e.g., fourth or bottom layer 304, and fifth or top layer 312) and sidewalls. The center region forms the fourth or bottom layer 304 of the top cushion support structure 114. The bottom layer 304 includes multiple apertures 306. A pair of sidewall regions 322a, 322b border the center region (e.g., layer 304) on opposite sides. When folded, the sidewall regions 322a, 322b will form outer sidewalls 318 of the top cushion support structure 114. A pair of second regions 320a, 320b border each of the two sidewall regions 322a, 322b. When folded, the second regions 320a, 320b will form the top layer 312 of the top cushion support structure 114. A second pair of sidewall regions 322c, 322d border the second regions 320a, 320b. When folded, the second pair of sidewall regions 322c, 322d will from a second set of sidewalls 318 that support the top layer 312 and separate the top layer 312 from the bottom layer 304.

In some implementations, the second pair of sidewall regions 322c, 322d can include interlocking tabs 324a-324d. The interlocking tabs 324a-324d can be used to retain the top cushion support structure 114 in the folded configuration, e.g., as shown in FIGS. 3B and 3G.

FIGS. 3C-3G illustrate the steps of folding the top cushion support structure of FIG. 1. As explained in reference to FIG. 3A above, the top cushion support structure 114 includes a second paperboard sheet 200 folded to form a second set of layers 302 (shown in FIGS. 3D-3G) to retain the one or more shipping objects 110a-110f in a spaced-apart arrangement within the shipping container 102.

Referring to FIGS. 3C-3G, the second set of layers 302 includes a fourth horizontal layer 304. The fourth horizontal layer 304 includes multiple second apertures 306. The second aperture 306 is sized to retain a second end 308a of the first shipping object 110a. Likewise, each of the second apertures 306 are sized to retain second ends 308b-308f of each of the objects 110b-110f, respectively. Each of the second apertures 306 are arranged to align with one of the first apertures 208 of the bottom cushion support structure 112 when the bottom cushion support structure 112 the top cushion support structure 114 are positioned in the shipping container 102.

Each of the second apertures 306 can be the shape of a circle (as shown in FIGS. 3A-3G), a square, or a rectangle. Each of the second apertures 306 can be the same shape. Alternatively, one or more of second apertures 306 can be different shapes. Each of the second apertures 306 are sized to form a friction fit with the respective second ends 308a-308f of the shipping objects 110a-110f.

In some cases, the first apertures 208 and the second apertures 306 are the same shape. For example, as shown in FIGS. 2G and 3G, the shipping object is a circular glass bottle and both the first apertures 208 and the second apertures 306 are round. In other cases, the first apertures 208 and the second apertures 306 are the different shapes. For example, the first ends 210a-210f of the shipping objects 110a-110f can be square (not shown), while the respective second ends 308a-308f of the shipping objects 110a-110f are circular, such as shown in FIG. 3G with a cap 310a covering an opening (not shown) of the shipping object 110a for pouring the contents out of the shipping object 110a.

In some cases, the second apertures 306 are smaller than the first apertures 208. For example, a diameter 308 (shown in FIG. 3A) of the second aperture 306 can be smaller than a diameter 242 (shown in FIG. 2A) of the first aperture 208a. Sometimes, the second apertures 306 are larger than the first apertures 208. For example, a diameter 308 (shown in FIG. 3A) of the second aperture 306 can be larger than the diameter 242 (shown in FIG. 2A) of the first aperture 208. Still in other examples, the second apertures 306 are the same size as the first apertures 208. For example, a diameter 308 (shown in FIG. 3A) of the second aperture 306 is the same as the diameter 242 (shown in FIG. 2A) of the first aperture 208.

As shown in FIGS. 3D-3G, the second set of layers 302 includes a fifth horizontal layer 312. The fifth horizontal layer 312 is above fourth horizontal layer 304. The fifth horizontal layer 312 is spaced apart from the fourth horizontal layer 304 by a height 316 (shown in FIGS. 3E and 3G). In some cases, the fifth horizontal layer 312 includes two separate regions 320a and 320b.

The top cushion support structure 114 includes third sidewalls 318. The third sidewalls 318 couple the fourth horizontal layer 304 to the fifth horizontal layer 312. The third sidewalls 318 are sized to maintain the fourth horizontal layer 304 spaced apart from the fifth horizontal layer 312. In some implementations, the third sidewalls comprise at least four sidewalls. In some cases, all of the third sidewalls 318 (e.g., sidewall regions 322a-322d) are all of substantially equal height.

The top cushion support structure 114 includes a retaining tab 324a. The retaining tab 324a is mechanically coupled to the third sidewall 318. The retaining tab 324a creates a friction fit with the third sidewalls 318. When the retaining tab 324a is engaged to the middle two sidewalls 218, the retaining tab 324a retains the top cushion support structure 114 in a folded form. The top cushion support structure 114 includes retraining tabs 324b-324d, substantially similar to retaining tab 324a.
