Inner packaging with cohesive coating
Various embodiments of packaging containers and packaging materials are provided to limit movement of the packaging materials and a product within the packaging container during shipment or transportation of the packaging container. Movement is limited by cohering the packaging materials to the packaging container.
1. Field of the Invention
The present invention generally relates to packaging containers and inner packaging materials. The present invention more specifically relates to packaging containers and inner packaging materials that each has a cohesive coating disposed on a portion thereof.
2. Description of the Related Art
Many types of packaging techniques are used to prepare products for transport between locations. Because products within packaging containers may have a tendency to move during transportation, different types of inner packaging materials have been used to stabilize or protect products during transportation. For instance, inner packing materials such as foam pieces, paper, contoured foam pieces, inserts and the like are used to fill voids defined between the product placed in a container and the container itself.
Each of these packaging techniques has drawbacks. For instance, using the small foam pieces does not necessarily secure the produce from movement within the container. Moreover, while the foam pieces admit of reuse, they often are discarded by the receiver of packaging and are fairly bulky and difficult to contain during disposal.
Paper may also be used in a similar manner to the foam pieces. Following insertion of a certain amount of paper within the container and placement of the product therein, the remaining voids between the product and the packaging can be filled with additional paper. Such a technique can crush more delicate products, such as flowers, for instance. Moreover, such a technique can cause marring of the surface finish of some products due to relative movement of the paper and the product during transport.
Another manner for protecting products within packaging is by the use of bubble wrap. Bubble wrap may be wrapped around the product and secured in place before the product and the bubble wrap are placed within the packaging. Once the product is enclosed in bubble wrap, an appropriate packaging container is obtained into which the product and the bubble wrap are placed. Again, bubble wrap admits of being reused but often is simply discarded and not reused. The bubble wrap also comes in longer sheets, which limits the placement of the bubble wrap protection relative to the product and the bubble wrap does not necessary limit movement of the product relative to an outer container. Therefore, packaging with bubble wrap also has significant drawbacks.
In some applications, cohesive singleface may be used to protect products during transportation. Singleface is a flexible wrap that consists of a single liner and has a fluted medium attached to one side of the liner. A cohesive material is disposed on the single liner that permits the singleface to adhere to itself. Singleface is often wrapped around otherwise vulnerable parts of furniture to protect the parts from impact or scratches during transportation. Because of its construction, singleface is very flimsy and is not suitable to provide a support surface for products in common packaging. For instance, because of singleface's flimsy qualities, even if it were used in packaging, it would not adequately secure the product within the packaging container.
Yet another manner in which packaging materials are used to insulate and secure products within packaging is by the use of formed or molded structures that are designed for specific products and packaging. For example, one or several pieces of foam may be used or cooperate with each other to enclose or secure a product before placement of the product within the packaging. The formed foam components can be expensive to manufacture and often can only be used with one specific product in one specific container. Thus, an undesirably large variety of formed foam components may need to be manufactured for use by a single company and the expense.
Products also can be secured in place on an inner board or member using wires, strings or tape. This technique is often found in the packaging of children's toys, such as larger dolls or action figures. While the inner board or member limits movement of the product relative to the outer container, wires or strings mar more delicate surface finishes and tape leaves a residue on the surface of the product.
SUMMARY OF THE INVENTIONDue to the shortcomings of the above-mentioned packaging materials, there is a need for packaging material that is not easily displaced during transportation of the packaging, that is easy and cost effective to manufacture, that may be reusable and easily stored, and that is less likely to mar the finish of products or crush more delicate products.
Thus, certain features, aspects and advantages of the present invention relate to packaging materials and methods of using such packaging materials. The packaging materials feature at least a pair of components that each has a cohesively-coated surface. The cohesive surfaces are arranged and configured to cohere to each other without significant sticking to the product being shipped. The components preferably limit movement of the product relative to the container. Advantageously, the coherence of the components allows the components to be generally moveably secured together such that the components can be fixed in one position and may permit subsequent fixing in another position.
In one arrangement, a packaging assembly is provided that comprises a corrugated component and a film. The corrugated component comprises a liner, at least a portion of the liner having a first cohesive coating disposed thereon. The film has a second cohesive coating disposed on at least a portion thereof. The first and second cohesive coatings are complementary such that the first cohesive coating will cohere to the second cohesive coating. The film is secured to the corrugated component by the first and second cohesive coatings.
Another aspect of the present invention involves a shipping box comprising a plurality of walls formed of a corrugated material. The corrugated material comprises at least two liners and at least one medium positioned between the at least two liners. A portion of at least one of the plurality of walls is treated with a cohesive coating. An insert is provided that is sized and configured for placement within the shipping box. The insert is formed of a second corrugated material. The second corrugated material comprises at least two liners and at least one medium disposed between the at least two liners. The insert has a portion thereof treated with a cohesive coating that is complementary to the cohesive coating of the shipping box. When the cohesive coating of the insert is placed for contact with the cohesive coating on the shipping box, the insert can be secured in position relative to the shipping box and the insert may permit some repositioning within the shipping box without destroying either the shipping box or the insert.
A further aspect of the present invention involves a method of preparing a packaging container for shipment or transportation of the packaging container with a product therein. The method comprising providing a packaging container having an inner portion thereof treated with a cohesive coating; providing a packaging material having a portion thereof treated with a cohesive coating that is configured to cohere with the cohesive coating of the packaging container, and cohering the packaging material to the packaging container by contacting a portion of the cohesive coating on the packaging material with a portion of the cohesive coating on the packaging container such that the packaging material coheres with the packaging container.
For purposes of summarizing the invention, certain embodiments, advantages and features of the invention have been described herein. Of course, it is to be understood that not necessarily all such embodiments, advantages or features are required in any particular embodiment of the invention.
BRIEF DESCRIPTION OF THE DRAWINGSThe above-identified features, aspects, and advantages of the present invention will now be described with reference to the drawings of several preferred embodiments, which embodiments are intended to illustrate and are not intended to limit the invention. The drawings comprise three figures.
With reference to the figures, certain embodiments will be described, which embodiments provide packaging containers and packaging materials and the applications of such. The packaging containers and/or the packaging materials can be formed from corrugated paper. At least two components have cohesive layers formed on them such that the two components can be secured together by coherence of the cohesive layers.
As used herein, corrugated paper can have its ordinary meaning and shall mean components having a single wall construction, a double wall construction and the like. As used herein, single wall can have its ordinary meaning and can mean a product formed with a pair of liners separated by a medium that can be fluted or otherwise formed to space the liners apart from one another. As used herein, double wall can have its ordinary meaning and can mean a product formed with three liners separated by a pair of mediums that can be fluted or otherwise formed to space the three liners apart from one another.
As used herein, a cohesive layer can be formed by a cohesive material, which has can have its ordinary meaning and can mean a coating that is applied to a substrate and sticks to itself. In some arrangements, the cohesive material is a formulate rubber latex. In other arrangements, the cohesive material is a non-latex material. As such, various formulated coatings may be used for the cohesive coating. For example, formulated natural rubber latex may be used for the cohesive coating in one embodiment. In other embodiments, either latex or latex-free coatings may be used. For example, APILCS-C and APILCS-D industrial and medical grade sterilizable latex coatings may be used, or APILFCS-2 and APELFCS-5 medical grade sterilizable latex-free coatings may be used. The particular coating selected can vary depending upon design goals of the packaging. For instance, coatings that attach more securely to other coated surfaces than to the liner can be used in packaging where partial or complete destruction of the coated surface is desired (e.g., to show a product has been removed for the packaging) while coatings that attach more securely to the liner than to other coated surfaces can be used in packaging where reuse or reconfiguration is a priority (e.g., storage of differing products in the same container). As used herein, complementary cohesive coatings are coatings selected such that the two coatings are configured cohere together.
With reference now to
The liner 16 preferably comprises a cohesive coating 20 that has been applied to at least a portion of the liner 16. The cohesive coating 20 can be applied to the entire surface of the liner 16 or can be applied to a select region or select regions of the liner 16, depending upon the application. As described above, the cohesive coating 20 can be any suitable material that sticks substantially only to itself. The coating 20 can be rolled onto the liner 16, can be sprayed onto the liner 16, can be painted onto the liner 16 or applied in any other suitable manner. In addition, the coating 20 can be applied to the liner 16 either before or after attachment of the liner to a medium to form a corrugated component. An advantage to coating after formation of the corrugated component is that the same stock can be used for coated and uncoated products. An advantage to coating before formation of the corrugated component is that the manufacturing process is simplified and the cost of manufacturing can be reduced. Coating before formation can be performed with certain corrugating machines, such as an AUSTRADE™ corrugating machine, for instance but without limitation.
The film 14 can have any suitable construction and is dependent upon the goals of the packaging. For instance, the film can be configured as an air bar, as a pouch, as a sheet, as a plurality of strips or straps or the like. Regardless of the structure, the film preferably is formed of a suitable polyethylene-based material although other materials can be used. The film 14 preferably comprises a cohesive coating 22 as well. The cohesive coating 22 allows the film 14 to stick to itself or to stick to the cohesive coating 20 that is present on the liner 16. The cohesive coating 20 can be applied to only one surface of the film 14. In some embodiments, the cohesive coating 20 can be applied to both surfaces of the film 14. Moreover, only portions of the film 14 can be coated in certain applications.
