CROSS REFERENCE TO RELATED APPLICATIONSThis application claims the benefit underTitle 35 United States Code §119(e) of U.S. Provisional Patent Application Ser. No. 62/118,110; filed: Feb. 19, 2015, the full disclosure of which is incorporated herein by reference.
BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates generally to accessories for portable ice chests and coolers. The present invention relates more specifically to a removable, external pocket accessory attachable to the exterior surface of a portable ice chest or cooler.
2. Description of the Related Art
Most portable ice chests and coolers currently on the market are specifically structured to contain food and drink products that are meant to be kept cold. While there are many portable containers in the nature of ice chests and coolers that also incorporate sections reserved for maintaining food at room temperature or heated, it is difficult to adequately isolate the cold side from the hot side. Efforts have still been made in the past to incorporate both hot and cold regions inside portable ice chests or coolers. Most of these previous efforts are complex and often fail to prevent the transfer of heat from the warm or room temperature portion into the cold portion of the portable ice chest. Some efforts have been made to create soft sided ice chests or coolers that have pockets positioned on the outside of the coolers in order to allow the user to transport items such as napkins, silverware, plates, etc., that do not need to be kept cold within the main enclosure of the cooler. Unfortunately, such soft sided coolers do not perform as well as rigid sided coolers and often sacrifice the ability to maintain products at a colder temperature within the cooler for the versatility of a flexible, soft sided cooler with pockets.
SUMMARY OF THE INVENTIONThe present invention therefore provides a removable, flexible, soft sided pocket that may be secured to the external wall of a rigid, rectangular box shaped ice chest or cooler. The rectangular box shaped pocket is generally configured in a width to height ratio that is similar to the largest external wall of a typical ice chest or cooler (usually the “front” of the cooler). The thickness or depth of the pocket (extending away from the rigid wall of the cooler) is small in comparison to its width and height. A zippered opening is provided across the top edge of the pocket. Most importantly, the top edge of the pocket and the bottom edge of the pocket each incorporate attachment flaps that run the width of the pocket and include two or more snap tops that are positioned to align with snap bases secured onto the rigid wall of the existing cooler or ice chest. The removable pocket may be snapped onto or removed from the sidewall of the rigid ice chest or cooler, leaving only the low profile snap bases on the cooler after removal. The present invention is preferably provided in a kit form that allows the user to retrofit an existing cooler with a pocket constructed in size and appearance suitable for association with the existing cooler or ice chest.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTSReference is made first toFIG. 1 which is a perspective view of the ice chest/cooler pocket of the present invention shown detached from an ice chest or cooler, but constructed and oriented to be positioned on an ice chest or cooler, once the appropriate matching snap connectors are installed on the cooler.
The terms ice chest and cooler are used interchangeably in the present disclosure and generally refer to any of a number of different types of ice chest or cooler designs, generally boxed rectangular in construction, that incorporate durable plastic exterior and interior walls separated by one or more layers of insulation material. A typical ice chest or cooler includes a hinged lid similarly constructed of an interior and an exterior plastic wall separated by a layer of insulation material. The manner of attaching the pocket structure of the present invention is, as described in more detail below, generally the process of securing snap connector bases to an external wall of the cooler and thereafter snapping the pocket structure to the external wall.
The example shown inFIG. 1 is preferably configured and shaped to fit on a medium sized ice chest or cooler having dimensions of 2-3 feet in width, 1-2 feet in depth, and 1.5-2 feet in height. The dimensions of the pocket shown inFIG. 1 therefore may preferably be on the order of 18 inches wide, 8 inches in height, and 1.5 inches in depth. Those skilled in the art will recognize, however, that as long as the size of the pocket is small enough to fit on the side of the selected ice chest or cooler, the construction of the pocket may be easily adapted to any size suitable for its intended purpose.
FIG. 1 disclosesice chest pocket10 as generally constructed withfront panel12 surrounded bytop box panel14, side box panel (left hand side)16, side box panel (right hand side) (not seen in this view) and bottom box panel (also not seen in this view). The stitching configuration for theice chest pocket10 is important. Preferably,front panel12 is stitched to the side box panels with internal stitching visible only inside the pocket, as well as withoptional top stitching17 as shown on side box panel (left hand side)16. Use of the optional top stitching facilitates the creation of a box like structure while maintaining the soft sided construction of the pocket.
Also seen inFIG. 1 is the manner in whichzipper closure22 is incorporated intotop box panel14.Top box panel14 is preferably secured to adjoining panels with internal stitching as described above, as well as with top panel top stitch (optional)15a&15bas shown.Zipper closure22 is secured in place on top box panel using zipper top stitch13a&13b.Zipper closure22 preferably runs the entire width oftop box panel14 and is opened and closed usingzipper pull24.Zipper closure22 may alternately extend part way down along either or both of side box panel (left hand side)16 and side box panel (right hand side)32 (FIG. 2).
Alternate to being constructed of discrete side panels that are stitched or sewn together,top box panel14, side box panel (left hand side)16, side box panel (right hand side)32, and bottom panel34 (FIG. 6) may be constructed from a single length of narrow material that is stitched tofront panel12 andback panel30. A further alternate embodiment might eliminatebottom panel34 and havefront panel12 stitched directly toback panel30 to form the pocket enclosure.
The most important features ofice chest pocket10 of the present invention aretop attachment flap18 andbottom attachment flap26. Each of theseattachment flaps18 &26 are secured into the seams of the box structure of the pocket at the back panel and side box panel interfaces, and at the top and bottom box panel interfaces.Top attachment flap18 incorporates optional topflap top stitch19 in order to provide a clean and secure appearance. In the preferred embodiment,flaps18 &26 are of double layer fabric construction finished with the respectivetop stitches19 &27.
In the embodiment shown inFIG. 1top attachment flap18 andbottom attachment flap26 each incorporate a set of four snap connectors.Top attachment flap18 comprises four spaced top flap attachment snaps20a-20d.In a similar mannerbottom attachment flap26 incorporates four bottom flap attachment snaps28a-28d.Each of these attachment snaps shown inFIG. 1 includes the top portion of a two part snap connector assembly. The bottom portions of the two part snap connector assemblies, not seen in the view ofFIG. 1, comprise part of the retrofit kit (seeFIG. 7) that provides the materials necessary to allow the user to install the removable pocket onto an existing ice chest or cooler. Attachment snaps20a-20dand28a-28dare preferably of stainless steel construction and, for the size shown inFIG. 1, may preferably be ⅝ inch diameter (for the cap portion of the snap) and ⅜ inch diameter for the stud portion of the snap. The top portions of the snap connectors are secured to the respective attachment flaps using a standard pressed rivet method of attachment.
Reference is next made toFIG. 2 which provides a perspective view of the reverse side of the ice chest/cooler pocket10. In this view the additional side box panel (right hand side)32 is shown with its optional right hand sidepanel top stitch33. More significantly, backpanel30 is disclosed in this view comprising the primary construction panel forice chest pocket10 parallel to and sized similar tofront panel12 shown inFIG. 1. Additionally inFIG. 2 the manner in whichtop attachment flap18 andbottom attachment flap26 are incorporated into the seams betweenback panel30 andtop box panel14 and bottom box panel34 (not seen in this view) is provided. Additionally, the open portions of each of the snap connectors20a-20dand28a-28dare shown structured to receive the stud portions of the standard two part snap connector assemblies.
Reference is next made toFIGS. 3 & 4 for detailed views of side box panel (left hand side)16 and side box panel (right hand side)32. These similar but opposite end views again show the manner in which optionaltop stitching17 &33 create a box like structure to thepocket10.Top attachment flap18 andbottom attachment flap26 are each shown secured into the box construction of the pocket at theback panel30 as described above. Further seen in the views ofFIGS. 3 & 4 is the manner in which top flap attachment snaps20a-20dand bottom flap attachment snaps28a-28dare secured within and extend through their respective attachment flaps. Once again these snap components are secured to the respective attachment flaps with a through the flap rivet attachment method that tightly secures this first of the two part snap connector components to the flap and therefore to the pocket as it is constructed during manufacture. Finally, inFIGS. 3 & 4 the overall depth of the pocket is seen in more detail withzipper closure22 and zipper pull24 positioned ontop box panel14 to allow alternate access to and closure of the interior ofpocket10.
Reference is next made toFIGS. 5 & 6 which provide a top plan view (FIG. 5) and a bottom plan view (FIG. 6) to complete the description of the various panels that go together to construct the box shapedpocket10.FIG. 5, a top plan view ofpocket10, shows in greater detail the manner in whichzipper closure22 extends across the overall width of the pocket from one end oftop box panel14 to the other. The various optional top stitches15a&15bsecuring the top panel to the back and front panels are also shown. Likewise, zipper top stitch13a&13bshow the manner in whichzipper closure22 is cleanly secured to the split material oftop box panel14.
As inFIGS. 3 & 4 described above,FIGS. 5 & 6 show the manner in which attachment snaps20a-20dand28a-28dare secured through the double layer thickness of attachment flaps18 &26. Optionaltop stitching35 forbottom panel34 is disclosed in more detail inFIG. 6. The manner in which the back and front panels are secured to the two sides, as well as the top and the bottom panels, is initially the same as most such fabric box construction methods. Initially constructed inside out, the various panels are sewn together and the overall pocket is then turned right side out. Top stitching as shown in the above described figures then secures the seam edges of the fabric to the top, bottom and side panels in a manner that better forms the rectangular box construction intended for the pocket. The four corners of the pocket, both back and front, are somewhat rounded as a result of the construction process, but this corner construction provides a rugged and secure manner of preventing separation between the various construction panels.
Reference is next made toFIG. 7 which is a top plan view of an assembly of components that includes the pocket device of the present invention, and is packaged together and sold as a retrofit kit suitable for installing the device of the present invention onto an existing ice chest or cooler.Ice chest pocket10 shown inFIG. 7 is constructed as described above, fully assembled and ready for installation onto an existing cooler.Retrofit kit40 includes the basicice chest pocket10 sized according to the needs of the user and the specific size of the cooler to be retrofit. Variousice chest pocket10 sizes may be specifically designated for each of the most popular types and sizes of ice chests and coolers.
Also included withinretrofit kit40 are hardware42 that includes snap base components and self tapping screws. As described above,ice chest pocket10 requires only an array of snap bases be positioned on the wall of the ice chest or cooler (seeFIG. 8 below) in order to be used in conjunction with the cooler once the snap bases are positioned and secured. As most ice chests and coolers comprise relatively thick walls made up of an external hard plastic shell and an internal softer insulation space, a typical self tapping screw used to secure the individual snap bases is sufficient to provide secure attachment of the snap base to the cooler. In order to allow the user to accurately position and place each of the snap bases with self tapping screws,retrofit kit40 further includestemplate44 which is a paper or thin plastic template that may be placed against the external wall of the cooler and used to guide the user's attachment of the various snap bases with self tapping screws. Light adhesive material may be positioned on the back oftemplate44 in order to facilitate the placement of the template and therefore of the snap bases on the external wall of the cooler.
Reference is finally made toFIG. 8 which showsice chest pocket10 of the present invention positioned and installed on an ice chest/cooler50 on the largest front wall surface of the cooler.
Although the present invention has been described in conjunction with a number of preferred embodiments, those skilled in the art will recognize modifications to these embodiments that still fall within the scope of the present invention. Because of variations in the sizes of different ice chests and coolers to which the present invention is intended to be retrofit, corresponding variations in the dimensions and configuration of the pocket are anticipated. Alternately, the present invention may be implemented through the manufacture and sale of a new ice chest or cooler with the pocket sold as an accessory included with the purchase of the new ice chest or cooler. Both the retrofit version of the present invention and the original equipment manufacturer (OEM) version incorporate the same basic elements and configurations.
