Description




BACKGROUND OF THE DISCLOSURE




1. Field of Invention




The present invention relates generally to a method and apparatus for cushioning an article. More specifically, the invention relates to a method and apparatus for cushioning an article to prevent damage during transport (i.e., shipping) of the article.




2. Description of the Background Art




Many articles are packaged with cushioning material to protect the articles from damage during shipping. Generally, cushioning material may be in the form of loose material or an insert positioned between the article and a shipping carton. The cushioning material prevents the article from moving during shipment, while providing a measure of impact protection from rough handling of the shipping container (e.g., a corrugated box). Examples of an article commonly shipped in this fashion include electronic devices, such as computers, stereos, television receivers, video players and the like.




A cushioning material commonly used to form shipping inserts is wood pulp fiber. Wood pulp fiber is desirable because it is light, easily molded, inexpensive and can be recycled. However, shipping inserts made from pulp fiber material have some disadvantageous aspects. For example, pulp fiber generally may not adequately protect electronic devices from some impacts commonly experienced during shipping. When shipping electronic devices, the shipping insert must have enough resiliency such that handling of the shipping container does not cause the insert to be permanently deformed. If the insert does not have enough resiliency to substantially recover to its original geometry after impact, the device may shift or move within the shipping container, thus increasing the probability of damage to the device.




Additionally, wood pulp material is susceptible to moisture, either from direct contact with fluids or humidity present in the environment. Wood pulp that absorbs moisture may lose its structural integrity and allow the insert to change shape (e.g., soften and collapse). Once softened, the insert may no longer restrain the electronic device, thereby allowing movement of the device within the carton, again increasing the probability of damage.




Therefore, there is a need in the art for a packaging material for protecting a device during shipping after once being impacted.




SUMMARY OF INVENTION




The present invention generally provides a packaging apparatus for the protection of an article during shipment. In one embodiment, a packaging apparatus includes a formed body having a first resiliency. The formed body has a plurality of recesses disposed on a first side of the formed body. An insert having a resiliency greater than the resiliency of the formed body is disposed in at least one of the recesses disposed in the formed body.




In another aspect of the invention, a method for packing an article is provided. In one embodiment, a method for packing an article includes determining one or more concentrated weight areas of the article; selecting one or more recesses formed on a body of cushioning material that correspond to the determined concentrated weight areas; and providing a material more resilient than the cushioning material into the selected recesses.

DETAILED DESCRIPTION OF INVENTION





FIG. 1

depicts an apparatus


100


for protecting an article during shipping. Generally, the apparatus


100


includes a body


102


of cushioning material having at least a first recess


104


and a second recess


106


formed on a first surface


112


of the body


102


. An insert


108


of resilient material is disposed in at least the second recess


106


.




More specifically, the body


102


includes a base


110


having a first surface


112


and a second surface


114


. A first projecting member


132


and a second projecting member


134


extend from the first surface


112


of the base


110


. In one embodiment, the first projecting member


132


includes a first wall


116


and at least a second wall


118


coupled by a first connecting member


120


. The first connecting member


120


, the first wall


116


and the second wall


118


define the first recess


104


therebetween. The first recess


104


, disposed on the second surface


114


of the base


110


, may be open between the walls


116


,


118


or enclosed by additional walls. Alternately, the first projection


132


may be formed within the first surface


112


as a unitary member or other geometry integrally incorporating the walls


116


,


118


and first connecting member


120


into a single member or shape.




The second projection


134


includes a third wall


122


and at least a fourth wall


124


coupled by a second connecting member


126


. The second connecting member


126


, the third wall


122


and the fourth wall


124


define the second recess


106


therebetween. The second recess


106


, which is disposed on the second side


106


of the base


110


, may be open between the walls


122


,


124


or enclosed by additional walls. Alternately, the second projection


134


may be formed within the first surface


112


as a depression or other geometry without the use of the walls


122


,


124


and second connecting member


126


. The body


102


may include additional recesses disposed on the first surface


112


of the base


110


, or on the second surface


114


of the base


110


.




The body


102


is comprised of a cushioning material that is used for protective packaging. The cushioning material generally is molded, formed, fabricated, shaped or otherwise forms a shape that is adapted to maintain an article in a spaced apart relation to a packing container. Examples of the cushioning material are wood pulp fiber, paperboard, corrugated paper, molded plastic and expanded plastic such as expanded polystyrene foam. In one embodiment, the body


102


is comprised of molded wood pulp.




The insert


108


is generally comprised of a material having a resiliency greater than the cushioning material. For example, the insert


108


, when utilized with a molded pulp body


102


, may be comprised of an elastomer or foamed polymer such as polyurethane. Generally, the insert material is able to recover to substantially its original geometry after an impact typically experienced during shipping or handling. In this manner, the efficiency of the apparatus for protecting an article is maintained such that subsequent impacts may be cushioned.




In one embodiment, the insert


108


is disposed in the second recess


106


. The insert


108


may be placed or dispensed in the second recess


106


such that the insert


108


adheres to the body


102


upon curing. Alternately, the insert


108


may be adhered to the body


102


using conventional adhesives. Additional inserts


108


may be disposed in other recesses.




Alternatively, the insert


108


may be loose or releasably disposed in the second recess


106


. The insert


108


may be adhered to the body


102


using a releasable adhesive, or the insert


108


may bond with the body


102


such that it is easily removed so that the insert


108


and body


102


may be separated for recycling. Alternatively, the insert


108


and body


102


may include a “snap-fit” so the insert


108


engages the body


102


in a manner that prevents separation of the insert


108


and body


102


without the application of an external force, such as provided by a person or automated equipment directed to perform this task. Loose inserts


108


generally fall free of the body


102


when not confined by a packing container (not shown).




Optionally, the insert


108


may include a surface


128


that is in a spaced-apart relation to the second connecting member


126


. The surface


128


and the second connecting member


126


define a gap


130


that traps a pocket of air. The air pocket trapped in the gap


130


provides an additional measure of impact resistance to the apparatus


100


. Optionally, the pocket or trapped air may be vented through a small passage that restricts rapid air movement into and out of the pocket.





FIG. 2

depicts a shipping container


222


utilizing another embodiment of an apparatus


200


for protecting an article


202


, for example, an electronic device such as a television receiver. The apparatus


200


is substantially similar to the apparatus


100


described above with reference to FIG.


1


. The apparatus


200


includes a first portion


204


and at least a second portion


206


. The first portion


204


is substantially orientated in a first plane


208


and at the second portion


206


is substantially orientated in a second plane


210


.




The first portion


204


includes a body


212


having a first recess


214


and at least a second recess


216


. At least the second recess


216


includes an insert


218


of resilient material disposed therein. In the preferred embodiment, the position of the insert


218


is selected to support the heavier portions of the article


202


to be protected during shipping. For example, if the article


202


is a television receiver, an area of weight concentration may be located under the picture tube


220


. The body


212


is formed such that the adequate recesses (and optionally other structural elements formed therein) maintain the article


202


in a predetermined spaced-apart relation to the shipping container


222


(e.g., a corrugated or other shipping carton).




In one embodiment, the first portion


204


is disposed beneath the article


202


. The second recess


216


is positioned below the picture tube


220


of the article


202


(e.g., television receiver). The insert


218


disposed within the second recess


216


prevents the body


212


from being deformed by the weight of the picture tube


220


, and thus maintaining the article


202


in the predetermined position throughout the shipping process until unpacked by the end user.




Optionally, additional recesses may be located on the first portion


204


. The additional recesses may be on the first or the second side of the body


212


. Some or all of the additional recesses may contain additional inserts


218


as desired to support the article


202


.




The second portion


206


of the body


212


generally contains a plurality of recesses that separate the article


202


from the walls of the shipping container


222


. Some or all of the recesses may contain inserts


218


to prevent deformation of the second portion


206


when subjected to lateral forces during shipping and handling.





FIG. 3

depicts a flow diagram of the method


300


of packaging according to the present invention. Specifically, at step


302


, the areas of concentrated weight for the article to be packaged are determined. The method


300


then proceeds to step


304


.




At step


304


, recesses in a body of cushioning material corresponding to the areas of concentrated weight are selected. The method


300


then proceeds to step


306


.




At step


306


, resilient material is provided into or inserted into each of the recesses selected at step


304


. As previously discussed, the resilient material provides selective cushioning (i.e., a localized area of resilient packaging protection) suitable for adapting the packaging of the present invention to the weight distribution of the article to be shipped or transported. The method


300


then proceeds to optional step


308


.




At optional step


308


, the inserted or provided resilient material is arranged in a manner insuring that a gap between resilient material and the body of the cushioning material is provided, thereby creating a pocket of trapped air. The pocket of trapped air further assists in cushioning the transported or shipped article. In other embodiments, the method


300


may contain additional steps such as removing the inserts or inserting other inserts in non-selected recesses.




The invention has been primarily described within the context of a formed body having an insert. However, it will be appreciated by those skilled in the art that the invention has general applicability to any shipping container utilizing materials that have been selected for their relative resiliency parameters or other parameters.




Additionally, it is within the contemplation of the present invention that the shapes of the recesses and inserts can be any other appropriate shape, e.g., semi-circular, etc. Further, the shapes of the respective recesses and inserts can be other than complementary.




Although the teachings of the present invention have been shown and described in detail herein, those skilled in the art can readily devise other varied embodiments that still incorporate the teachings and do not depart from the spirit of the invention.
