[0001) The present invention relates to a portable container, more particularly an ice chest or cooler for food and beverages.

[0002) Conventional coolers or ice chests are typically in the form of an insulated container body defined by four walls upstanding from a base to define a top opening to which a removable or pivotable lid is mounted. Such conventional coolers are typically rectangular with two elongated side malls and two end walls, with pivotable handles mounted to each end wall for carrying the cooler.
Such ice chests have a number of disadvantages. For example, the elongated shape of conventional large, e.g., 36 or 48 quart, coolers means that the consumer must spread his arms and wrists wide to be able to grab at both handles to lift and move the cooler. This awkward stance makes lifting the cooler difficult and often the consumer will solicit aid from another indi idual so that C't7ol...F iZ
one person carries each end of the ,e~e~e. ~S~nd, the elongated footprint of conventional cool ca~n~make it difficult to store and transport, particularly in compact cars, while accommodating the consumer's other luggage or belongings. The footprint of the product is also of concern as it impacts the space required to display the product for sale. ' BRIEF DESCRIPTION OF THE INVENTION

[0003] It is an object of the invention to provide a cooler or ice chest that is uniquely shaped to be more . ; 's.
ergonomic so that the consumer does not need to spread his arms and wrists as wide to pick up the ice chest. It is also an object of the invention to provide a cooler having a smaller footprint to facilitate storage and efficient retail display.

[0004) The foregoing objects are realized in accordance with the invention by providing an ice chest that is of generally cubical shape having a generally square transverse cross-section.

[0005) It is further object of the invention to provide an ice chest that may be more conveniently and easily picked up irrespective of the direction from which it is approached and carried. The foregoing object is realized by providing a handle on each side face of the cooler so that handles can be readily located and grasped irrespective of the orientation of the cooler with respect to the approaching consumer.

[0006] It is a further object of the invention to provide for built in storage to accommodate goods or accessories that the consumer may wan t transport or store with the ice chest, but which t~\~ require cooling. The foregoing object is achieved ,~~y''/~pJr~oviding a cooler or ice chest having at least one covered storage compartment in its lid.
[000?) It is yet a further object of the invention to provide a cooler tray within the cooler in a manner such that the tray can be placed and retained in any one of several lateral positions within the ice chest interior.
I This object is achieved by providing a cooler tray having a lip defined peripherally thereof for engaging r r ~j ~ ~n ~ m, , .~I

DETAILED DESCRIPTION OF THE INVENTION
[00?lJ An ice chest provided in accordance with the present invention is of generally cubical shape so that the ice chest has a smaller footprint than a conventional ice chest and is easier to grasp and lift.
[002?) In the illustrated embodiment, the ice chest 10 is in the form of an insulated container body 12 which has walls 14,16,18,20 upstanding from a base 22 to define a top opening 24. For ease of~.description and reference, the ice chest may be characterized as having front and rear side walls 14,16 and right and left side walls 18, 20. The right and left side walls are mirror images of one another and the front and rear side walls as ~. ~~.~1 a:'.s ,''.~' tE°~a ~,.~i tk;J) i;~ ,~~ '~~~..:'..n .~( ~':'''~"~~;'~
~ ,, il..~. , r ._,:~~
defined by the shell of the cooler are mirror images of one another but the top edge of the front and rear side walls as defined by the liner 28 differ to accommodate the openable lid of the cooler as described in greater detail hereinbelow. The container body 12, as best seen in FIGURES 7 and 8, is comprised of an outer shell 26 arid an inner liner 28 with a suitable insulating material 30 provided therebetween.
[0023] To define the generally cubical shape of the ice chest, the ice chest lid 32 and base 22 are generally square and each of the upstanding walls is generally square having a width generally equal to its height. -n the illustrated emi~odiment, the ice chest is generally cube shaped, but not necessarily a perfect cube, as the height of the ice chest in this embodiment is slightly greater than the dimensions of each of the sides. Thus, by way of example, for a 48 quart ice chest, the dimensions of the ice chest may be I7 1/4 X I7 1/4 X 17 5/16 inches. The corners and peripheral edges of the ice chest are generally curved or rounded to facilitate molding, to give the product a modern aesthetically pleasing appearance, and for user comfort.
[0024) unlike conventional ice chests, in the presently preferred embodiment, the ice chest includes four handles 34,36,38,40, one handle defined on or mounted to each side wall of the ice chest. This permits the consumer to more conveniently and easily pick up and carry the ice chest from any direction in which it is approached. The cubic shape in conjunction with the handles makes this possible. In the illustrated embodiment, the handles 34,36 provided on the front and rear side walls are r .~i .....~ n~~~h ~ ,' . ;i"." ,~~, ~,~ y::.i' -~ ";:i ' .. , ,.....~i N .i' .....;

....., molded in the outer shell 26 of the ice chest. On the other hand, the handles 38,40 provided in the right and left side walls 18,20 are pivotally mounted to a suitable receptacle 42,44 defined in the liner 28 for being pivoted from a storage position, as shown in FIGURE 1, to a lift and carry position, as shown in FIGURE 2. In the illustrated embodiment, the liner and shell of the ice chest are molded to define a raised perimeter 46,48 for the right and left side handles 38,40, e.g., to shield the handles from potentially damaging contact with other objec~s when stowed. As also illustrated, e.g., in Figures i-4, the cross bars of the pivotabie handles 38,40 include finger recesses 50,52 to facilitate graspiag of the handle and for user comfort.
[0025) In the illustrated embodiment, an integrally formed handle 34,36 is provided on the front and rear side walls 14,16, e.g., so as not to interfere with opening the lid and/or the hinge mounting of the ice chest lid. It is to be understood Lhat if the lid is mounted without a hinge structure or is hinged to one of the side walls, then the front and rear handles may be configured as pivotal handles such as shown for the right and left sides and/or may be another pivotal or nonpivotal handle configuration as deemed necessary or desirable. Likewise, while pivotal handles that project upwardly above the lid of the ice chest are provided on the right and left sides to- facilitate grasping and lifting of the ice cooler and/or for dragging the ice chest, e.g., in the sand, the handles provided on the right and left sides of the ice chest need not be provided as pivotal handles but may be vertically sliding G

handles or integrally formed handles as deemed necessary or desirable.
[0026] An insulating cover or lid 32 is provided to close the top opening 24 of the ice chest. In the illustrated embodiment, the lid is hingedly attached to the liner 28 of the ice chest main body 12 as at 54 to pivot from a closed position as shown in FIGURE 1 to an open position, as shown in FIGURE 4, to provide easy access to the ice chest interior. It is to be appreciated, however, that as an alternative to the pivotal connection sho~~rn, a fully removable lid may be provided. Also, the lid could be hingedly attached to one oz the other sides of the cooler without deoartincr from this invention.
(0027] To secure the lid in its closed position as depicted in FIGURE l, in the illustrated embodiment locking tabs 56 are defined adjacent the upper peripheral edge of the container main body liner to engage corresponding recesses 58 defined in each side of the cooler lid 32. Such a friction type locking closure is not required, however, and may be omitted. In addition, or in the alternative, other more affirmative locking structures may be provided to secure and retain the lid in its closed position, such as pivotally mounted locking carrying handles to selectively engage and hold the lid on the container, during lifting and transport, or pivoting or rotating locks provided specifically for retaining the lid in its closed position. In the illustrated embodiment, because the lid is secured in its I
closed position by the locking tabs 56 and corresponding recesses 58, no locking interface is provided between the ..~.. ~~1 ..'~ '~~~' :1:::H ~G..~~ '~.-.:4 :i'~.~ ~: !~.~i ..; ; ~.~~ ~--~i ~.~ii H..A~
.. ;r-.. ~~..;, .._ ,i pivotal handles and the lid. Rather, a cutout 60,62 is ' defined on the right and left side edges of the lid to facilitate rotation of the handles to a vertical disposition as shown in FIGURE 2. To facilitate lifting and opening of the lid, particularly to overcome the friction locking force of the locking tabs and corresponding recesses, a lid lifting recess 64 is defined in the lid front edge. In the illustrated embodiment, a corresponding recess 66 is defined in the top edge of the liner 28 of the main body 12 to facilitate opening of the lid and for aesthetics.
[00?SJ The ice cooler lid 32 in the presently preferred er~bodimer.t or: the invention also defines compartments for product storage. In the illustrated embodiment, first and second compartments 68,70 are provided as receptacles for a beverage can, glass or bottle. Additionally, a pivotal cover 72 is mounted to the lid 32 which may be selectively pivoted from a closed position as shown in FIGURE 1 to an open position as shown in FIGURE 3 to reveal interior compartments in the cooler lid. In the illustrated embodiment, first and second compartments 74,76 are defined in the lid which may receive cellular phones, car '.keys, change and the like. The compartments may be defined in a removable tray insert or may be integrally formed in the ice chest lid.
[0029] In the illustrated embodiment, the lid or cover for the compartment pivots to 'slightly beyond 90°- such as 100 or 110y so that the cover will stay open while the compartments) are accessed, without precluding placement of a bottle, can or glass in the beverage receptacles 68,70. In the illustrated embodiment, the compartment :'~J.. ir.:i: .... ~ ~"k ii~a"i..'i; 'e '~ ;~ ~~ ~i:~!! _~~~ .::lL..a~~ !I;'li ....'.w w cover is snapped shut by the engagement of cover tabs 78 and corresponding receptacles (not shown). A recess 80 is defined in the lid 72 and a projecting tongue 82 in the cover 72 to facilitate gripping and lifting of the lid so as to overcome the snap-lock frictional closure afforded by the container cover tabs 78.
[0030] A recess 84 is also defined peripherally of a compartments 74,76 so that when the compartment cover 72 is in its closed position, the peripheral surface 86 of the compartment tray engages or is closely adjacent the inner surface of the compartment cover 72 so as to close and isolate each of the compartments 74,76. Because the cover snaps shut, it will retain contens in the respective compartments even when the ice chest lid is disposed in its open orientation as shown in FIGURE 4.
As illustrated in FIGURE 4, a recess or pocket 90 is defined in the ice chest lid 32 inner surface which provides added height to the storage compartment of the ice chest. As will be appreciated, such a pocket or recess is not provided in the forward section of the lid due to the presence of the accessory compartments 74,76.
[0031] As illustrated in particular in FIGURES 3, 7, 8 and 9, the bottom 22 of the ice chest 10 has a flared foot 92,94,96,98 at each of its four corners. The flared feet provide greater stability and more cold retention capability for the ice chest. In this regard, the flared feet effectively define a recess in the bottom wall of the ice chest as they space the bottom surface of the ice chest main body 12 from the support surface on which the ice chest is disposed.
i i [003?] In addition to the ergonomic advantages, E
facilitated by the new handle configuration, the cube i shape of the ice chest also reduces the foot print of the product which facilitates storage, and placement in compact vehicles, e.g., smaller, deeper compact vehicle ~~
i trunks. The reduced product footprint is also of importA~
to retailers. In that regard, for example, for a 48 quart cooler, a cubic ice chest as provided in accordance with the invention has a 25$ smaller footprint on a retail shelf then does a 48 quart ice chest of standard rectangular configuration. The reduced footprint is a desirable =eat_.re to retailers who can display more products fo- resale.
[0033] In accordance with a further feature or the invention, a unique cooler tray 100 is accommodated and held within the liner 28 of the ice chest main body 12 such that -t will not slide back and forth within the ice chest. rlore specifically, with reference to FIGURE 10, the liner 28 of the illustrated ice chest is formed to include raised panels 102,104 in the interior surface of the four side walls. The liner is correspondingly recessed as at 106,108 in the outer surface of the liner structure. The panel projections 102,104 define an upward facing ledge 110,112 for seating a tray. In the illustrated embodiment, tray tabs 114,116 are defined to project upwardly from the inner most face of the protruding panels, beyond the 'respective ledge 110, 112.
These tabs hold the cooler 'tray 100 in position as described in greater detail below.
[0034] An ice cooler tray 100 in accordance with an exemplary embodiment of the invention is illustrated in ~~ 1~..;i ,.~ ., .: .. ~ ,F.," ~ y :s;;w ~ .~~ ~ ~' ..::a ~. v' 4..~ .::5-.,x .,:i; 1..~ ~y~ . , ' ,fir :., L_»

~ FIGURES 4, I1 and 12_ As illustrated, the tray is generally rectangular having curved corners. The bottom 118 of the tray is perforated as at 120 so that any fluids such as from melted ice will not be retained in the tray and the contents of the tray can remain relatively dry, suspended above the lower portion of the ice chest interior. The curvature of the corners of the tray and its length are such that the curved corners can be accommodated in the curved interior corners of the ice chest as shown in FIGURE 4. The rectangular tray is constructed and arranged so that it will fit within the liner 28 either front to rear or side to side (as shown in FIGURE 4) This is possible due to the square shape of the ice chest vnterior. Meanwhile, as illustrated in FIGURE 12, the upper peripheral edge of the tray defines a peripheral surface 122 and a downwardly depending lip or flange 124,126.
[0035j The lip or flange 124, 126 is sized so as to be received between the tray tabs 114,116 of the ice chest liner and the respective side wall of the liner- Thus, for example, when the tray is seated within the main body 12 of the ice chest, as shown in FIGURE 4, the lip 126 of the long side of the tray 100 will be seated on the ledge 112 of the liner and the tray tabs 116 will be limit the amount by which the tray may shift towards the front side 14 of the ice chest. Similarly, the lip or flange 124 provided along the short side.of the tray will engage one of the two tray tabs 114 defined on the right and left side faces of the liner to support and hold the tray in position in a like manner. In the same way, the tray can be mounted to extend front to back along either the right or left sides 18,20 of the ice chest. Furthermore, in ,:»i~'~ "~,ct~:~~~; ~'~i,1~ ~'e ; ~",~':, -:n ;~'-=I'.

the illustrated embodiment, the tray tabs 114 provided on the right and left side walls are provided and spaced., apart so that they can both be received under the peripheral lip 124 of the tray so that the tray can straddle rhP ~~~~~-°r °~ the right to left side walls.
Tabs 116 are similarly spaced so the tray can straddle the ice chest front to rear, so that ~OU'~
ultimately the tray has e-ix possible positions within the cooler: G~ree front to back positions and tie right to left or left to right positions. Thus, an advantage of I
providing a cooler tray and tray tabs, as illustrated and described hereinabove, is that a variety of tray positions can be accommodated while unintended lateral shifting of the tray will not occur.
[0036] While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not to be limited to the disclosed embouiment, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
