The described embodiments relate generally to packaging. More particularly, the present embodiments relate to packaging using opposing pivot points such that a cushioning effect is produced during an impact.
Product packaging is an integral part of a customer's experience. It introduces the customer to their product, and can affect the customer's feelings toward the product and the company that created it. Even intermediate packaging, such as components that are designed to provide cushioning in transit and not package the finished good, may impart a brand image to the ultimate product. This is especially true for companies that wish to move toward a single stream recycling solution for their packaging. In general, current high performing cushioning structures usually are made of plastic materials such as expanded polystyrene. And retention films used are similarly constructed from non-environmentally friendly materials. While these materials provide adequate cushioning, they are not environmentally friendly and use nonrenewable resources for their raw material.
In contrast, some more environmentally friendly materials such as molded fiber structures may be prone to permanent deformation. While these materials may absorb the energy of a single impact, past components risk losing their dimensions, absorption and retention properties, etc. after a single or very few impacts. If a company wishes to use materials such as molded fiber in these types of applications, a past solution would be simply to add additional layers, complex substructures, etc. that add both weight and cost. This weight and cost still may not realize the benefit of elastic properties, e.g., when used to support certain products or finished goods boxes. And in the case of finished goods boxes that also use environmentally friendly materials (e.g., cellulose based materials), additional cushioning is further desirable to enhance the robustness in terms of impact and vibration protection.
What is needed is a new molded fiber structuring paradigm that can absorb repetitive impacts while maintaining shape through design innovations that give the finished components elastic properties similar to expanded polystyrene, foams, etc.
The disclosure will be readily understood by the following detailed description in conjunction with the accompanying drawings, wherein like reference numerals designate like structural elements, and in which:
Reference will now be made in detail to representative embodiments illustrated in the accompanying drawings. It should be understood that the following descriptions are not intended to limit the embodiments to one preferred embodiment. To the contrary, it is intended to cover alternatives, modifications, and equivalents as can be included within the spirit and scope of the described embodiments as defined by the appended claims.
As described above, the packaging described herein provides a cushioning solution utilizing environmentally friendly materials, such as molded fiber (or other cellulose-based material). Cushioning elements are described that achieve cushioning properties from forced friction interaction between two opposing pivot points that are allowed to flex due to offset load designs, and interaction between component features. In general, the opposing pivot points direct and focus impact energy outward, downward, or both, thereby increasing the time of product deceleration during an impact. In some embodiments, the cushioning element is configured such that its side walls bow or flex inward, toward the product, and further limit movement when the product would otherwise be subject to vibration or other movement.
Some embodiments include packaging including a cushioning element comprising molded fiber. The cushioning element includes a pair of opposing flexure points that are configured such that an impact is absorbed. The cushioning element may be formed from a top component and a bottom component (e.g., top and bottom molded fiber panels) that are adhered together near respective peripheries to fix them together in a spatial relationship. The remainder of the components may be free of adhesion, except for a controlled friction interface at the opposing flexure points. The flexure points may engage one another through a friction interface, such that the bending flexure of the respective components is controlled through a predetermined distance of travel that is controlled by the friction between the top panel and the bottom panel of the cushioning element. The opposing flexure points are allowed to flex due to offset load absorption and the forced friction interaction between the two opposing pivot points.
The top and bottom panels of the cushioning element may be contoured such a a single panel may bend or contour to provide a product support surface, sidewalls, flanges, etc., similar to a deep drawn sheet metal or thermoplastic part. In some embodiments, the top and bottom panel of the cushioning element may be a continuous sheet. The bending or flexure of the top panel and bottom panel during an impact may further cause a sidewall of the cushioning element to flex or bow inward, thereby effectively squeezing a product therein. The respective components may be formed of the same material or different materials (e.g., different cellulose-based material). For example, the top panel may be made from molded fiber, and the bottom panel may be made from greyboard. The cushioning element may be configured as an end cap.
A finished package may include other components such as a lower box or tray, a lid, or additional end cap/cushioning elements. The lower box may wholly envelop the bottom surface of the cushioning element such that it is not visible to a customer. The cushioning element may hold or support a finished product, a finished good box, or the like.
Advantageously, this improves upon prior systems having, for example, expanded polystyrene components, that are less environmentally friendly than molded fiber components. By designing appropriate cushioning elements using molded fiber by taking advantage of opposed flexure points and forced friction interaction between two molded fiber panels, impact resistance and elasticity can be achieved through molded fiber components.
Advantageously, components described herein may provide a completely fiber based alternative to traditional expanded polystyrene, foam, or flexible retention film shipper designs used in previous packaging. Through these designs, smaller footprints are achievable thereby increasing shipment efficiency. Further, the smaller footprints also reduce shipping costs, e.g., relatively expensive air freight costs.
Companies may be sensitive to the cost of packaging and may wish to promote packaging that is eco-friendly. Certain packaging materials are higher cost due to their processing, and while engineers may be able to design single-component packaging, the cost may be prohibitive for certain materials. Optimization of packaging in material usage may help keep costs low, and if done well may not interfere with, and may promote, a positive user experience. Packaging made out of recyclable and/or biodegradable materials, such as paper or other cellulose-based products can reduce environmental impact. Packaging that is interesting in character and well-executed may boost a product's or a brand's reputation, thereby attracting new customers and retaining previous customers.
In utilizing eco-friendly materials such as molded fiber structures, prior designs may be more prone to permanent deformation during shipping. As described above, while these materials may absorb the energy of a single impact, past components risk losing their dimensions, absorption and retention properties, etc. after a single or very few impacts. Packaging described herein improves on past designs, and provides eco-friendly components that may absorb multiple impacts due to their resilient design, and protect against potentially harmful vibrations during shipping without adding additional components, complex substructures, etc.
Packaging described in this document achieves these and other beneficial characteristics by balancing structural robustness, eco-friendly materials, and aesthetic elements.
To keep the product protected and secure during transport, handling, or storage, the molded-fiber cushioning element may include molded recesses or features to hold various components, documents, and products. A lid or other cushioning element for example may cover the product and the molded-fiber cushioning element when the packaging is closed. A product contained by the packaging may be, for example, an electronic device such as, for example, a laptop, tablet computer, or smartphone, or it may be a non-electronic device, such as, for example, a book.
In some embodiments, the packaging may be retail packaging (i.e., finished packaging for containing and conveying a product to a user such as may be used in a retail setting, not shipping packaging for containing a packaged product during shipment) that one may expect to find on the shelf in a retail store, and which one may open after purchase to directly access their product. In that case, one or more end cap type components described herein may be coupled to one another to enclose a product, e.g. with a hinge and closure mechanism for example.
These and other embodiments are discussed below with reference to the accompanying figures. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes only and should not be construed as limiting.

Cushioning element 100 may include lowermost surface 116, for example extending below upper component 200 and formed from lower component 300. Lowermost surface 116 may be configured to rest inside a box, or on top of any other support surface such as another cushioning element 100, product, finished goods box, etc. During manufacturing, the components 200 and 300 may be adhered together at adhesion regions 132 and 120 (e.g., pressed together with pressure sufficient to activate an adhesive within adhesion regions 132 and 120, where the adhesive is a pressure sensitive adhesive). In some embodiments, the peripheries of components 200 and 300 may be cut out after the components 200 and 300 are adhered together. The components 200 and 300 may be formed as a panel, contoured such that sidewalls 128 may form a cavity to receive a product therein. Interior sidewalls 128 may define an interior periphery that transitions into the product support surface 122 and allows the product support surface 112 to flex relative to the adjacent sidewall.
A vertical distance X1 is shown between lowermost surface 116 and panel 112, which is adhered to upper component 200 at adhesion region 120. Panel 112 also interacts at a friction interface 126 between upper component 200 and lower component 300. In some embodiments, there may be no friction interface, and the components may be separated. In some embodiments, there may be a contact interface, without the interface being a friction interface. If a product contained within cushioning element 100 transmits a downward impact force on product support surface 122, e.g., if the packaging is dropped, cushioning element 100 provides elasticity and protection during an impact event, or predetermined force applied to product support surface 122. It is through the forced interaction of frictional contact at friction interface 126 that flex regions or points 124 and 123, respectively flex and bend such that vertical distance X1 decreases. If a product contained within cushioning element 100 transmits a downward impact force on product support surface 122, e.g., if the packaging is dropped, cushioning element 100 provides elasticity and protection during the impact event. The frictional interface may allow for translation of components 200 and 300 such that the impact is absorbed without damage to cushioning element 100.

As shown in
Cushioning element 100 may be formed of molded fiber (e.g., entirely formed of molded fiber). As described, the opposing flexure points 124 and 123 are configured as opposing flexure points such that an impact may be absorbed, and allow for elasticity in a molded fiber cushioning element, flexing in opposing mechanical directions while still absorbing energy downward. That is, while flexure point 124 may still deflect downward, the surfaces deflecting open adjacent angles during the impact, while flexure point 123 results in a downward deflection and a closing of the angle between, for example, surface 116 and panel 112. The flexure points may engage one another through a friction interface, such that the bending flexure of the respective components is controlled through a predetermined distance of travel (e.g., the difference between distance X1 shown in
Cushioning element 100 is hollow top and bottom panels 200 and 300 include open space between the friction inter face between them and the points where they are attached to one another. This reduces the ultimate weight of cushioning element 100, and allows the freedom of movement between top and bottom panels. Additionally, this configuration hides and protects friction interface 126 during use.
As shown, top and bottom panels 200 and 300 of cushioning element 100 may be contoured such that a single panel may bend or contour to provide a product support surface, sidewalls, flanges, etc., similar to a deep drawn sheet metal or thermoplastic part. In some embodiments, the top and bottom panel of the cushioning element may be a continuous sheet that is bent or formed back onto itself to provide for the upper and lower components/panels. As described, the bending or flexure of the top component 200 and bottom component 300 during an impact may further cause a sidewall 128 of the cushioning element 100 to flex or bow inward, thereby effectively squeezing a product or finished good box therein. The respective components may be formed of the same material or different materials (e.g., different cellulose-based material). For example, the top surface may be made from molded fiber, and the bottom surface may be made from greyboard. The cushioning element may be configured as an end cap.
The packaging components may be composed of a recyclable material (e.g., a biodegradable or compostable material). If and when the customer opts to dispose of the packaging, because the entire packaging is recyclable and cellulose-based, the packaging may simply be recycled without requiring material separation (e.g., in a single-stream recycling program). Advantageously, this improves upon prior systems having, for example, expanded polystyrene, foams, or plastic film retention systems, which provide cushioning or impact protection but not afford an environmentally friendly solution. By designing the opposing pivot points and frictional interface between the corresponding features of the molded fiber cushioning element 100, an environmentally friendly solution is provided it still results in secure packaging, resilient impact protection, and aesthetically pleasing packaging components.
Packaging 10, including cushioning element 100, is constructed to give a clean, unitary appearance. This helps to reinforce its high quality and robust character, and that of the product. To achieve this appearance, seams, gaps, and raw material edges are minimized (raw material edges are edges formed by cutting through a flat material, where the substance of the material between its outer flat surfaces is revealed). Packaging 10 may be a particular color, e.g., a brand-identifier color. In some embodiments, visible surfaces of packaging 10 may be predominantly white. In some embodiments, components of the packaging may be folded from one or more sheets, such that when folded over and adhered together there is no raw edge on the outside of the component or packaging 10. In some embodiments, components of packaging 10 may be constructed with multiple blanks.
Components of packaging 10, such as cushioning element 100, may be formed from one or more blanks, or molded fiber components. In some embodiments, the blank is formed of a single continuous substrate, such as, for example cellulose-based material like cardboard or paperboard. In some embodiments, lower cost and robust material such as corrugated cardboard or greyboard is used for a portion of cushioning element 100, which may be formed from one or more blanks, for example in non-customer facing surfaces. In some embodiments, interior surfaces of the cushioning element 100 may be surface treated or coated, for example with a coating to protect the finished good box 400, or product. Tabs, flaps, and regions without adhesive of the blank are folded such that no adhesive is visible in finished packaging 10. In some embodiments, adhesive may be omitted and the various flaps and tabs attached in another suitable manner (e.g., by mechanical interlock or press fit). Fold lines may be formed, for example, by weakening the substrate along the lines, such as by perforation, material crushing, scoring, miter cutting, etc.
In some embodiments cushioning element 100 may be formed from one or more molded fiber components, and each molded fiber component may include particular die cut features specifying dimensions for critical points in a given application, such as the forced friction interface, the flexure pointer region, and various cutouts to accommodate additional packaging components, or goods, such as products.

Cushioning element 500 may include corresponding features described with reference to cushioning element 100 without limitation.
In some embodiments, any surface finishing may take place after the components are cut from the blank, or alternatively prior to the blank being cut into separate sheets for assembling to a final product. Additionally, some operations may be performed concurrently. All or some of the surfaces of the packaging may be coated, or laminated, which may increase structural strength properties such as rigidity and which may protect a product within the packaging, or avoid scratching.
Additionally, the packaging may be manufactured in a cost-effective and environmentally-friendly way. In some embodiments, the packaging components may be constructed of a single integrally-formed piece of material. The single integrally-formed piece of material may be a foldable material that is folded into a configuration that holds and secures a product, either alone or within a cavity of a packaging container. In some embodiments, the foldable material may be a single piece of material that is cut by a single operation (e.g., a single die-cutting operation). In some embodiments, the foldable material may be die cut from a stock material e.g., a sheet or roll of material), or molded fiber. Single integrally-formed pieces of material that are cut by a single cutting operation may facilitate efficient and reproducible manufacturing. Moreover, such manufacturing may reduce waste by reducing waste material during manufacturing.
