Abstract
An inflatable air packaging device includes a tubular, inflatable member surrounding an object receiving pocket. The pocket is configured in a shape and size to receive, retain, and suspend an object. The inner and outer surfaces of the member are secured to one another to form a plurality of apertures. Each aperture is configured to receive a portion of the object to suspend the object within the pocket. In one embodiment, there are four apertures which each receive a corner of a rectangular object. The device provides a circular air cushion chamber which is disposed around a perimeter of the object. Forces applied to the device are uniformly distributed around the device to minimize the effect on the object.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention is related to air packaging devices and more specifically to air packaging devices to support and retain an object therein.




2. Relevant Technology




Conventional packaging devices incorporate a variety of materials to protect and insulate a packaged item. One of these conventional packaging materials is known as “bubble-pack.” Bubble-pack consists of two layers of thin plastic material, such as polyethylene or vinyl formed with random bubbles between the layers and filled with air at time of manufacture. Bubble-pack requires large rolls of bubble material that displace a great deal of volume in storage before use.




Bubble-pack is bulky, and therefore expensive to ship and to store during the period before it is put to use. Furthermore, conventional bubble-pack provides limited protection in certain applications because of the fixed bubble diameter, height, and count in a given material area.




Another conventional packaging material is pre-shaped styrofoam objects. An example of this is styrofoam “peanuts,” which are distributed in mass around a packaged article. Another example is pre-formed styrofoam blocks which are fitted to restrain a packaged item. Styrofoam blocks prevent the packaged item from moving in directions during travel. Styrofoam material experiences some of the same disadvantages of the bubble-pack. Styrofoam material is bulky and expensive to ship and store. Furthermore styrofoam provides limited protection in certain applications because of the fixed dimensions and shape of the styrofoam.




Inflatable packaging devices have overcome some of the limitations of previous packaging materials. Inflatable packaging devices may be shipped and stored in a deflated condition, thereby reducing the expense of shipment and storage. Furthermore, inflatable packaging devices provide cushions of filler material, such as air, which is under pressure. The filler material functions to absorb and redistribute forces acting on the packages, thereby protecting a delicate item of merchandise encapsulated and suspended therein. Articles encapsulated by the inflatable packaging device are prevented from substantially moving in directions relative to the packaging.




The following list of patents disclose several improvements of inflatable packaging devices and are hereby incorporated by reference:




U.S. Pat. No. 4,597,244, issued Jul. 1, 1986 for “Method For Forming An Inflated Wrapping;”




U.S. Pat. No. 4,793,123, issued Dec. 27, 1988 for “Rolled-up Packaging System and Method;”




U.S. Pat. No. 4,872,558, issued Oct. 10, 1989, for “Bag-In-Bag Packaging System;”

U.S. Pat. No. 4,949,530, issued Oct. 21, 1994, for “Method for Forming Bag-In-Bag Packaging System;”




U.S. Pat. No. 5,272,856, issued Dec. 28, 1993, for “Packaging Device That is Flexible, Inflatable, and Reusable and Shipping Method Using the Device;”




U.S. Pat. No. 5,427,830 issued Jun. 27, 1995, for “Continuous, Inflatable Plastic Wrapping Material;”




U.S. Pat. No. 5,445,274, issued Aug. 29, 1995, for “Inflatable Package Insert;”




U.S. Pat. No. 5,447,235 issued Sep. 5, 1995, for “Bag With Squeeze Valve and Method For Packaging an Article Therein;”




U.S. Pat. No. 5,487,470 issued Jan. 30, 1996, for “Merchandise Encapsulating Packaging System and Method Therefor;”




U.S. Pat. No. 5,588,532 issued Dec. 31, 1996, for “Self-Sealing Inflatable Bag and Method For Packaging an Article Therein;” and




U.S. Pat. No. 5,711,691 issued Jan. 27, 1998 for “Self-Closing and Self-Sealing Valve Device For Use With Inflatable Structures.”




Some of the above patents disclose air packaging devices involving distinct, separate pouches or bags that are manufactured from two or more plies. For example, several of the inventions disclose a four-ply bag, which are used to form outer and inner chambers. The outer chamber is inflated with a filler material, such as air and is separated from the inner chamber. The inner chamber retains the packaged item, thereby providing a total air cushion around the product.




A disadvantage of some of these air packaging devices is that they fail to properly suspend, insulate, and protect an item. Commonly, this is because the devices fail to protect an item from g-forces in one particular direction as they do not evenly distribute such force. Thus, items which are particularly sensitive to force in one plane are at risk. Furthermore, the shapes that some packaging devices take when inflated may not be convenient for packaging in containers having cubical dimensions.




It would, therefore, be an advancement in the art to provide a packaging device which better insulates an item and evenly distributes g-forces to which an item may be subject. Forces in a particular plane would therefore be minimized. It would further be an advancement in the art to provide a packaging device with advantages of the air packaging devices which could be used within cubicle containers. Such an invention is disclosed and claimed herein.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




A preferred embodiment of the invention is now described with reference to the

FIGS. 1-8

, where like reference numbers indicate identical or functionally similar elements. The components of the present invention, as generally described and illustrated in the Figures, may be implemented in a wide variety of configurations. Thus, the following more detailed description of the embodiments of the system and method of the present invention, as represented in the Figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of presently preferred embodiments of the invention.




Referring to

FIG. 1

there are shown overlying panels


10


which may be incorporated into an embodiment of the present invention. The panels


10


include a pair of outer panels


12


and inner panels


14


which may be configured in various shapes including a general rectangular shape. The panels


10


may be configured into shapes that are substantially similar to one another. The inner panels


14


are disposed between the outer panels


12


and the panels


10


are connected to one another such as by sealing or by using other conventional methods. Such sealing methods include heat sealing the panels


10


at select areas to form a packaging device of the present invention.




The panels


10


are preferably composed of a flexible, gas impervious composite laminate. Currently preferred composite laminates are adapted to melt in the range of 300 degrees F. The panels


10


of the device may be formed from a variety of polymers comprising various amounts of polyethylene, nylon, and metallocene. Such types of composite laminates are well known in the art.




Referring to

FIG. 2

, and with continued reference to

FIG. 1

, a plan view of one embodiment of a deflated inflatable packaging device is shown. The device


16


, comprises the four overlying panels


10


shown in FIG.


1


. The outer panels


12


include peripheral edges


18


which are sealed to peripheral edges


20


of the inner panels


14


to thereby create first and second chambers (not shown). The peripheral edges


20


of the inner panels


14


are further sealed to one another.




The device


16


further comprises an air exchange passage


22


to provide communication between the first and second chambers of the packaging device


16


. The air exchange passage


22


may be formed by forming adjacent apertures in the inner panels


14


. The apertures are sealed together along their perimeters to create the air exchange passage


22


. The passage


22


allows communication of a filler medium between the first and second chambers. In this manner, the first and second chambers create a main chamber and communication is maintained throughout the device


16


.




The packaging device


16


further incorporates a flow channel


24


which is disposed on an outer panel


12


and in communication with the first or second chamber. The flow channel


24


may be any number of various devices for filling the chamber with a filler medium such as air. In one embodiment, the flow channel


24


may be a push-pull valve. The push-pull valve allows for inflation and deflation of the device


16


to permit reuse. The flow channel


24


may also be embodied as a flat valve such as that disclosed in U.S. Pat. No. 5,711,691. Ideally, the flow channel


24


is leak free and is strategically located on the packaging device


16


to allow easy inflation of the main chamber and to minimize contact between the flow channel


24


and an exterior container.




The device


16


may further comprise one or more corner apertures


26


that accommodate a comer or other protruding portion of an object to be shipped. A comer aperture


26


may be created by sealing the outer and inner panels


12


,


14


together to define a perimeter


28


and an interior


30


. The perimeter


28


is entirely sealed to prevent communication between the interior


30


and the main chamber. The interior


30


represents portions of the outer and inner panels


12


,


14


that is not inflatable and is not part of the main chamber.




The material of the interior


30


may be removed or otherwise punched out to provide an egress for a portion of an object. Alternatively, the material of the interior


30


may not be removed or may be partially removed.




In the embodiment of

FIG. 2

, the interior


30


is configured with slots


32


. The slots


32


act to separate the material as a corner of an object is inserted into the comer aperture


26


. Referring to

FIG. 3

, a comer


34


of an object is shown as it is introduced into the corner aperture


26


. The slots


32


allow the material


31


to yield and conform to the comer


34


. The excess material


31


in the interior


30


acts to strengthen the perimeter


28


of the corner aperture


26


and absorb shocks to the device


16


. The added strength of the excess material


31


is advantageous when shipping heavy objects which may otherwise tear out the perimeters


28


that define the corner apertures


26


.




The slots


32


may be configured in various shapes and sizes including a “+” or cross shape. The slots


32


may also be configured such that a plurality of slots


32


are disposed perpendicular to another slot


32


as shown in FIG.


2


. One of skill in the art will appreciate that the configuration and disposition of the slots


32


may vary and such variations are included within the scope of the invention.




In an alternative embodiment, the material of the interior


30


is retained intact. In such an embodiment, the material yields and conforms to an object that is introduced into the corner aperture


26


.




The corner apertures


26


receive angular portions or corners of rectangular, triangular, and other angularly configured objects to suspend a device (i.e. a laptop computer) within a pocket of the device


16


. The corner apertures


26


may be sized to the object to optimize the grip and retention capability. Thus, configuration of the corner apertures


26


may be based on weight, size, and dimension of the object being shipped. The device


16


may be configured with four corner apertures


26


for a rectangular object or three comer apertures


26


for a triangular object. In the embodiment of

FIG. 2

, the device


16


is disposed with two comer apertures


26


between each outer and inner panel


12


,


14


. The corner apertures


26


are spaced based on the size of the object to be shipped. With square shaped objects, the comer apertures


26


may be disposed substantially equidistant from one another.




Referring once again to

FIG. 2

, the device


16


is shown with a quilt


40


. A quilt


40


is formed by sealing an outer panel


12


to an adjacent inner panel


14


. One or more quilts


40


cause the packaging device


16


to conform to a desired shape when inflated. By appropriately placing the quilts


40


, the inflated device


16


may approximate square, round, hexagonal, etc. shapes. In the embodiment of

FIG. 2

, the quilt


40


is formed between both pairs of outer and inner panels


12


,


14


. Thus, a mirror quilt


40


is formed between the opposing outer panel


12


and inner panel


14


not shown in FIG.


2


.




The quilt


40


allows communication within the first or second chamber. Thus, the quilts


40


do not traverse the entire longitudinal length of the device


16


as they must allow for continued air flow within the chamber. Although the quilts


40


may define sub-chambers within a chamber, all sub-chambers remain in communication with one another. One of skill in the art will appreciate that the number and disposition of the quilts may vary and are included within the scope of the invention.




Referring to

FIG. 4

, is a plan view of one embodiment of the inflated device


16


is shown with an object


42


(shown in dotted lines) contained therein. The inflated device


16


is configured to conform around the object


42


. The quilts


40


and the peripheral edges


18


assist in conforming the inflated device


16


into the desired shape. As a filler medium


24


is introduced into the first and second chambers


44


,


46


, the chambers


44


,


46


communicate with one another to provide equal pressure.




As discussed previously, the first and second chambers


44


,


46


may be collectively referred to as a main chamber


48


. The desired result is to provide a chamber


48


that traverses around a perimeter


50


of an object


42


. The inner panels


14


of the device


16


define a pocket


52


with top and bottom openings. An object


42


is inserted into the device


16


with the comers


34


extending into the corner apertures


26


to retain and protect the object


42


. The device


16


may therefore be described as a tubular inflatable device that circumscribes a perimeter


50


of an object


42


.




Referring to

FIG. 5

, a perspective view of one embodiment of the inflated device


16


is shown. When the device


16


is inflated it may have approximately 1 to 2 inches of cushion barrier between the outside and inside of the device


16


. In the embodiment shown, the comer apertures


26


are configured with the material completely removed from the interior


30


.




Referring to

FIG. 6

, the inflated packaging device


16


is shown with an object


42


contained therein and inserted into an exterior container


54


. The exterior container


54


may be economically embodied as corrugated cardboard, but may also be embodied as wood, plastic, metal, etc. The exterior container


54


may be rectangular in configuration. Depending on the application, a plurality of devices


16


may be inserted into an exterior container


54


. The main chamber


48


of the inflated packaging device


16


provides a cushion around the perimeter of the object


42


for compression against the exterior container


54


or other devices


16


. The device


16


further provides a cushion around the object


42


for all axes.




The cushion generates an appropriate amount of force to resist compression for controlling the g-forces exerted on the object


42


when free-fall dropped. The force to compression length ratio may be selected to provide low g-force results during free-fall drop testing. The quilts


40


may assist in conforming the device


16


to increase contact with the exterior container


54


. Greater contact with the exterior container


54


minimizes the gravitational forces applied to the packaging device


16


.




Referring to

FIG. 7

, a plan view of an alternative embodiment of the device


16


is shown wherein the panels


10


are configured with rounded corners


55


. As the packaging device


16


may be commonly inserted into an exterior container


54


the corners may be subjected to stress and wear. The rounded corners reduce the amount of stress and wear to provide a more resilient device


16


.




The device


16


provides a circular air cushion chamber which is disposed around a perimeter of an object


42


. When the device


16


is inflated, the object


42


is securely suspended within the pocket


52


. The main chamber


48


of the device


16


works in harmony with the exterior container


54


to create a suspension ring. The outer surfaces of the device


16


are constrained by the exterior container


54


and push against the exterior container


54


on all sides or axes of the device


16


.




Contact locations between the device


16


and the exterior container


54


are outer suspension points


56


. As shown in

FIG. 6

, the device


16


contacts the exterior container


54


at six locations. This includes four contacts along the perimeter of the device


16


and bottom and top surface contacts. The corner apertures


26


engaging the corners


34


of an object


42


are inner suspension points


58


. The embodiment of

FIG. 6

includes four inner suspension points


58


based on the four corner apertures


26


. The combination of inner and outer suspension points


58


,


56


act in harmony to suspend and protect the object


42


.




Forces applied to the exterior container


54


and the device


16


are distributed throughout the inner and outer suspension points


58


,


56


. The suspension points


58


,


56


and the main chamber


48


create a distribution of force at the suspension points


58


,


56


and dampen the g-forces. The force of a drop is distributed among the six outer suspension points


56


and the four inner suspension points


58


. In conventional apparatuses, the suspension points do not act in harmony and do not equally distribute the force. Thus, the prior art devices are subject to more g-force loading in one direction than another. This advantage is more fully appreciated when objects are more sensitive to external force in one plane than another. With such objects, the present invention provides superior protection than that afforded by the prior art.




As shown in

FIG. 6

, when the device


16


is inserted into a properly sized container


54


, the inner and outer suspension points


56


,


58


are separated from the corners


60


of the exterior container


54


. This is advantageous as corners


60


are frequently subject to the most abuse during shipping. The device


16


should therefore be used in conjunction with a properly sized exterior container


54


to support and position the device


16


.




Referring to

FIG. 8

, a plan view of an alternative embodiment of the inflated device


16


is shown wherein the device


16


is configured to accommodate a triangular shaped object


42


. As such, the device


16


is configured with three corner apertures


26


to accommodate the three corners


34


. The device


16


may further be configured with three pairs of outer and inner panels


12


,


14


that are sealed together to form three chambers


62


. The three chambers


62


would be in communication with one another to form a main chamber


48


as in the previous embodiment to provide a cushion around the perimeter


50


of the object.




One of skill in the art will appreciate that the number of apertures


26


disposed on the device


16


may vary depending on the nature of the object


42


to be shipped. The device


16


may therefore have four apertures


26


to accommodate a rectangular object


42


and three apertures


26


to accommodate a triangular object


42


. Thus, the device


16


may have two or more apertures


26


depending on the shape of the object


42


to be shipped.




Referring to

FIG. 9

, a plan view of an alternative embodiment of the device


16


is shown. In this embodiment, the device


16


comprises a single outer panel


12


and a single inner panel


14


(not shown) which are sealed to one another along their upper and lower peripheral edges


18


,


20


. The ends


64


of the panels


12


,


14


are further sealed to one another to form an inflatable main chamber


48


in a ring configuration.




An air exchange passage


22


may further be formed between the sealed ends


64


to allow communication between the ends


64


. The device


16


further includes apertures


26


as previously described which are formed between the outer and inner panels


12


,


14


. The device


16


is further configured with a flow chamber


24


to provide inflation of the main chamber


48


. The device


16


may further be configured with one or more quilts


40


as previously described.




One of skill in the art will appreciate that the number of inner and outer panels


14


,


12


to form inner and outer surfaces of the suspension packaging device


16


may vary and are included within the scope of the invention. For example, in an alternative embodiment a single panel may be used that has peripheral ends sealed to itself to create a main chamber


48


with inner and outer surfaces. The inner and outer surfaces may then be sealed to one another to form comer apertures.




The invention is therefore not limited to an exact number of panels


10


. It is sufficient to have inner and outer surfaces forming an inflatable main chamber


48


. The inner and outer surfaces are further connected to one another to form corner apertures


26


. The main chamber is then disposed entirely around a perimeter of an object


42


to provide a cushion barrier. An object


42


may then be inserted into a pocket


52


formed by the inner surface and suspended by the corners


34


engaging the apertures


26


.




It should be appreciated that the apparatus and methods of the present invention are capable of being incorporated in the form of a variety of embodiments, only a few of which have been illustrated and described above. The invention may be embodied in other forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive and the scope of the invention.
