Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates generally to a collapsible cooler liner used in a common hard shell receptacle. 
       BACKGROUND OF THE INVENTION 
       [0002]    The present invention generally relates to portable coolers, specifically a collapsible liner that is received in a common hard shell receptacle to function as a thermally insulated receptacle. Picnic goers, Little League baseball game attendees, party guests, concession operators, and myriad other people having the need for a cooler within which to store cold drinks and ice, have all felt the need for a common and heretofore nonexistent device, a collapsible and portable cooler that is easily transportable to the site of the picnic, game or event, which does not consume a large amount of space to transport and which can store a large quantity of drinks in a bath of ice. 
         [0003]    Thermally insulated containers have become popular for carrying articles that are best served cool, most commonly beverages, but also things like salads and candy that are prone to melt. Portable thermally insulated containers tend to be one of two types, either a hard shelled insulated container or a soft sided insulated container. Hard shelled portable thermally insulated receptacles tend to be made of molded plastic, with an inner wall and an outer wall, and with an air insulation space between them designed to keep the contents at a temperature different from the outside air. Hard shell coolers are substantially rigid and, as a result, depending on their size, not very portable. That is, for a large event at which it is desirable to keep 80-100 drinks cold, a cooler has to be very large. In addition to the significant size dimensions and the transportation difficulty a large cooler presents, such a cooler is also very, very heavy and difficult to transport. Often, large coolers require two people to carry such a cooler from a car to the field or booth. 
         [0004]    Soft sided coolers, on the other hand, generally comprise an inner wall and an outer wall with an insulating layer between them with all three layers made of flexible fabric. Soft sided coolers are generally collapsible and erectable by, for example, folding down side panels, making them much more transportable than hard shell coolers. However, the size of an effective softshell cooler is very limited, because the collapsible sidewalls will not be able to support nearly the number of drinks and ice as a hard shell cooler, often necessary for a large event. The prior art includes many examples of soft sided coolers, including some that are combined with hard shell liners, such that a hard shell plastic inner liner is received in a softshell outer skin. Other softshell coolers are designed to receive structural members to make them rigid. The problem with softshell coolers is that they are not rigid enough to be very big, and are generally limited to individual use. 
         [0005]    The requirements of an effective cooler are simple. A thermally insulated receptacle capable of storing drinks and ice in it that retains water in it is desirable, so that as ice melts it doesn&#39;t leak out, and which is large enough to store the drinks, food items and ice to keep everything cold. In the past, most coolers have been constructed from a hard shell material, such as plastic or Styrofoam, and for large coolers serving a large number of people, such coolers occupy a lot of space while being transported. While there are a number of prior art devices that are soft shell collapsible type coolers, all are either size limited or require structural members to be installed or erected at the site that must be transported with the soft shell cooler. Otherwise, they remain flimsy softshell containers, the sides of which are not rigid enough to retain any significant weight of drinks and ice that is desirable to be stored such as for a large group or event. The present invention addresses this problem by providing liners to be received in common receptacles. 
         [0006]    While liners for some common receptacles such as five gallon buckets, and large garbage cans and tall kitchen garbage cans are well known, e.g. garbage bags that are sized to fit those receptacles, and such liners are available in every grocery store in the United States, such liners and bags are not insulated, nor are they intended for reuse. Significantly, they fit into the receptacle but do not cover, disguise or camouflage the receptacle that they are retained in. When those prior art liners are placed in garbage cans, it is still very apparent that they are garbage cans. Generally, only a small extension over the top rim is provided, so the receptacle is still largely in view. In addition, the liners are thin, single ply liners that look like garbage bags and frequently tear, compromising the necessary water retaining features, so they are not very suitable as a means for turning such a receptacle into a cooler. Similarly, while liners for five gallon buckets are well known in the prior art, they are generally used so that multiple uses of the bucket are possible, for example, as a receptacle for different colors of paint, or different tools or supplies to be stored therein. None of these prior art bucket, garbage can or receptacle liners are insulated, nor are they intended to be thermal liners to maintain a temperature in the bucket, nor do they camouflage or disguise the nature of the receptacle being used, whether the five gallon bucket, garbage can or other receptacle. 
         [0007]    In providing an innovative receptacle liner for common receptacles, it is desirable to include accessory article retention devices, for example insulated can holders and accessory holders, on a cooler, and a number of prior art hard shell coolers have included can holders, for example, in the lid of the cooler. Prior art soft shell coolers, due to the lack of rigidity and size limitations, have not generally been provided with accessory article retention devices. 
         [0008]    The present invention provides a thermally insulated soft sided liner, large enough to accommodate a large number of drinks and ice, yet it is still very portable and collapsible. An innovative feature of the cooler liner of the present invention is that they are sized and designed to be received and retained in large, commonly available hard shell receptacles, such as a 5 gallon bucket, or a common tall kitchen garbage can, or a large garbage can. The innovative liner includes provisions for securely attaching to the common receptacle in ways that do not interfere with the handle or transport provisions of the common receptacle while still disguising and camouflaging the hard shell receptacle by providing large overhanging flaps that serve the multiple purposes of disguising the nature of the receptacle and providing a device to which accessory retention devices, i.e. can holders and the like, are secured. Providing an insulated liner that turns buckets and garbage cans into coolers, while camouflaging the fact that garbage cans and buckets are being used, eliminates the need for large, bulky and difficult to transport hard shell coolers.

       SUMMARY OF THE INVENTION 
       [0031]    The present invention is a collapsible cooler liner comprising pliable members erected and connected to approximate the inner dimensions of a common hard shell receptacle. Overhanging flaps extending from the upstanding pliable members are provided wherein the overhanging flaps are downwardly depending and further include means for securing the liner to the hard shell receptacle. The overhanging flaps extend downwardly to cover a substantial portion of the hard shell receptacle, thereby disguising the nature of the hard shell receptacle. 
         [0032]    The means for securing the liner to the receptacle are incorporated into the downwardly depending flaps and comprise closure devices that are alternatively detachable and permanently connected closure devices. The downwardly depending flaps have relief cuts between them which are connected after the liner is placed into the hard shell receptacle to secure the liner to the receptacle. The closure devices effecting the securing of the liner to the receptacle comprise any of a number of alternatives, including a cinch cord and locking clasp, zipper, cooperating hook and loop fastening strips, button snaps, or spring loaded clamps, magnets and other devices that secure the downwardly depending flaps together after they are folded down. The closure device is alternatively a permanently connected closure device, such as a cinch cord and locking clasp, or a detachable closure device, such as cooperating hook and loop fastening strips, magnets or button snaps. 
         [0033]    The collapsible liner of the present invention is provided with a watertight inner sleeve, an inner cylindrical portion to be contained within the hard shell receptacle which is free of any seams or stitch connections or perforations. The inner sleeve comprises the inside layer of a multiple layer open cylinder, there being also a corresponding middle insulating cylinder layer and an outer fabric layer. The inner sleeve, preferably formed from a molded sheet of durable material, is secured to the outer fabric layer at the top of the open end of the inner sleeve and the outer fabric layer. They are secured together using any of various methods, including without limitation stitching or welding or fusing them together. In the preferred embodiment wherein they are stitched, the seam is entirely outside the inner cylindrical portion to be contained within the hard shell receptacle such that the watertight nature of the inner cylindrical portion is not compromised. 
         [0034]    The downward depending flaps are provided on various preferred embodiments of the present invention for different hard shell receptacles such that, when the flaps are folded down and connected, they do not interfere with the use of the handles of the receptacles. Relief cuts in the upper portion of the collapsible liner are sized and oriented to provide access and use of the handles of the receptacle while still substantially camouflaging and covering the remainder of the receptacle. 
         [0035]    The collapsible liner of the present invention also includes accessory retention straps secured to an exterior side of the downwardly depending flaps. The collapsible cooler of the present invention also includes a lid secured around the top of the collapsible cooler. 
         [0036]    The exterior side of the downwardly depending flaps is provided such that it can imprinted, embossed, engraved or embroidered to display logos, insignias, indicia and emblems. In a preferred embodiment of the present invention, the upper portion of the inner sleeve comprises the exterior side of the downwardly depending flap, and is constructed from a material onto which logos, insignias, indicia and emblems may be applied and displayed. It is also contemplated within the principles of the present invention that the downwardly depending flaps may be provided with hook and loop fasteners to receive panels with coordinated hook and loop fasteners, the panels having logos, insignias, indicia and emblems applied thereon.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0051]    The present invention comprises a cooler  10  as shown in  FIG. 1  having a soft sided inner liner  12  received in a hard shell outer container  14 . In a first preferred embodiment, the liner  12  is positioned in a receptacle comprising a common five gallon bucket, but other receptacles are contemplated and the use thereof does not depart from the principles of the present invention. The liner  12  has downwardly depending flaps  16  and accessory pockets  18 ,  20 ,  22  secured thereto holding, for exemplary purposes, a drink  19 , a bottle opener  21  and a deck of cards  23 . Drinks are retained within the cooler  10  in an ice bath  24 . In a preferred embodiment a lid  26  is secured to the liner  12  at a hinge point  28  whereby the lid  26  can be laid over and secured to the top of the inner liner  12  to prevent sunlight from hitting the ice bath  24 . The lid  26  is secured to the liner  12  at closure means  27 ,  29  to accommodate transport of the cooler  10  from one location to another to minimize spillage of the contents. In a preferred embodiment the closure means  27 ,  29  comprise a first cooperating side of a zipper  29  on the liner  12 , and a second cooperating side  27  on the lid  26 . However, other cooperating closure devices  27 ,  29  such as, for example, Velcro, button snaps, magnets and other similar devices are contemplated by the principles of the present invention. 
         [0052]    The inner liner  12  is shown isolated apart from the hard shell in  FIG. 2 , with an essentially cylindrical portion  30  approximately the height of the inner wall of a commonly available hard shell receptacle such as, without limitation, a typical five gallon bucket. Flaps  32 ,  34  shown upstanding in  FIG. 2  prior to installation of the liner  12  in hard shell receptacle  14  are illustrated with relief cuts  33 ,  35 . In a preferred embodiment, the flaps  32 ,  34  are provided with closure means  36 ,  38  comprising coordinating tabs  36 ,  37 ,  38 ,  39  that are used to secure the flaps  32 ,  34  to each other upon installation into the common hard shell receptacle  14  and folding down of the flaps  32 ,  34  such that they are downwardly depending as shown in  FIG. 1 . In a preferred embodiment, the tabs  36 ,  37 ,  38 ,  39  comprise detachable cooperating closure means such as for example hooks and loops fasteners, button snaps, a zipper, magnets and other cooperating devices that secure the tabs  36 ,  37 ,  38 ,  39  together and thereby secure the liner  12  within the hard shell receptacle  14 . In a significant aspect of the present invention, the downwardly depending flaps  32 ,  34  when folded down, cover a substantial portion of the hard shell receptacle  14 , as shown in  FIG. 1 . The principles of the present invention contemplate that the flaps  32 ,  34  of the liner  12  will cover approximately one-third (⅓) to one-half (½) of the hard shell receptacle  14 . By providing such large downwardly depending flaps  32 ,  34  the nature of the receptacle  14  is disguised and camouflaged such that it is not apparent to the casual observer that common receptacles such as a five gallon buckets or garbage cans provide the structural support for the liner  12 . 
         [0053]    Alternatively, a preferred embodiment of the present invention is illustrated in  FIG. 3  wherein liner  12  is provided with a permanently connected closure device comprising a cinch cord  40  threaded through sleeves  41  formed in the flaps  32 ,  34  and a locking device  42  on both sides. After installation of the liner  12 , into the receptacle  14  and folding down of the flaps  32 ,  34  the cinch cord  40  is pulled taut to pull the flaps  32 ,  34  tightly around the exterior of the receptacle  14  to secure the liner  12  therein. In one specific application of the present invention, a typical five gallon bucket is provided as shown in  FIG. 4  having an upper lip  44  and a lower ring  46  between which a handle  48  is pivotally connected at retention rings  50 ,  52 . To install a liner  12  in the bucket  14 , as shown in  FIG. 5 , the liner  12  is pushed down into the bucket  14  until the bottom of the liner  12  reaches the bottom of the bucket  14 . The liner  12  is a preferred embodiment of the present invention having detachable cooperating means depicted by snap buttons  62 ,  64 . In the application depicted in  FIG. 5 , when the flaps  32 ,  34  extend downwardly on a receptacle  14  having a handle  48  it is necessary to provide such separable, detachable closure means  62 ,  64 . The liner  12  is installed such that the relief cuts  33 ,  35  are immediately above the handle retention disks  50 ,  52 . The flaps  32 ,  34  are folded down as shown in  FIG. 6 , with one flap  30  being bunched and pushed down through the handle  48 . After being folded down, the flaps  32 ,  34  extend below the lower ring  46  of the five gallon bucket, such that when a closure mechanism  60  on the flaps  32 ,  34 , in this case comprising coordinated snap buttons  62 ,  64 , is connected, the liner  12  will be secured in the bucket  14 , with the lowest point of the flaps  32 ,  34  secured below the lower ring  46  of the bucket  14 . When the flaps  32 ,  34  are folded down and connected at the tabs by coordinated snap buttons  62 ,  64 , a substantial portion of the bucket  14  is hidden and camouflaged by the liner  12  to be placed in the bucket  14  and the flaps  32 ,  34  folded down through the handle  48  and connected to secure the liner  12  in the bucket  14 . An alternative embodiment of the present invention, depicted in  FIG. 3  with a permanently connected closure device such as the cinch cord  40  and locking mechanism  42  could be used with a bucket without a handle  48  that does not require bifurcation or separation of the fold down flaps  32 ,  34 . 
         [0054]    As shown in  FIG. 7 , the liner  12  preferably comprises three layers of material. The innermost layer comprises a molded sleeve  60  of mylar having relief cuts  62 ,  64  therein, the sleeve  60  being an open top cylinder formed in a mold. The mylar sleeve  60  is watertight and is molded so that there is no stitching that will be below the level of the hard shell receptacle that would create an opportunity for water to leak therethrough. The mylar sleeve  60  is received in a similarly shaped insulating foam cylinder  66 , the foam cylinder  66  having relief cuts  68 ,  69  corresponding to the relief cuts  62 ,  64  in the inner mylar sleeve  60 . In the most preferred embodiment of the present invention, the foam cylinder  66  comprises multiple panels of open cell foam insulation material sewn together in the shape of the cylinder  66 . The combination of the mylar cylinder  60  and foam cylinder  66  is then received in an outer fabric sleeve  70  having relief cuts  72 ,  74  that correspond with and align with the relief cuts  62 , 64  in the mylar sleeve and relief cuts  68 ,  69  in the insulated foam cylinder  66 . 
         [0055]    In a significant aspect of the present invention, the mylar sleeve  60 , the insulating foam sleeve  66 , and the outer fabric sleeve  70  are sewn together along the top and the relief cuts only. There is no stitching, opening or compromise of the solid watertight sleeve  60  below where the liner  12  will engage the top lip of a hard shell receptacle to prevent any leakage of water out through the stitch holes. Maintaining the watertight nature of the sleeve  60  and preventing water from seeping into the foam cylinder  66  is accomplished by forming the inner sleeve  60  as a molded cylinder and not compromising its integrity with stitching or seams. 
         [0056]    The beneficial use of the liner  12  is depicted in  FIGS. 8 and 9  wherein flaps  32 ,  34  are secured together by a closure mechanism  60  such that it is connected tightly below the lower ring  46  of the bucket and covers a substantial portion of the bucket  14 , thereby obscuring and camouflaging the nature of the bucket  14 . In this way, the liner  12  is securely retained in the bucket  14 . Furthermore, when the flaps  32 ,  34  are folded down, the relief cuts  33 ,  35  allow the handle  48  to continue to operate because they do not interfere with the pivot receptacles  50 ,  52 . Accessory pockets  18 ,  20  are shown in  FIG. 8  secured to the downwardly defending flap  34 . In  FIG. 9 , the cooler  10  of the present invention is depicted with the downwardly depending flaps  32 ,  34  secured allowing access to the handle  48  while a lid  80  is positioned on top of the inner liner  12 , so that a user can put the lid  80  on the cooler and still carry it at the handle  48 . It is contemplated that the lid  80  may be secured to the liner  12  in a variety of ways, as shown in  FIG. 1  by closure means  27 ,  29  comprising any of a zipper, hooks and loops fastening strips, button snaps, magnets and other cooperating devices. 
         [0057]      FIG. 10  illustrates the three layer construction of the inner liner  12  in a blown up cross section view of the liner  12  in the bucket  14 . Specifically, an interior layer  60  of mylar is provided that is watertight so that, if the ice melts in the liner, it does not leak through to the foam insulation layer  66 . In the most preferred embodiment of the present invention, the insulating layer  66  comprises sheets of open cell foam that provide a layer of insulation between the inner mylar layer  60  and the outer plastic shell  70 . Water is prevented from seeping through the inner sleeve  60  to the foam insulation layer  66  by forming a molded sleeve  60  and maintaining its watertight integrity by not stitching or sewing or otherwise perforating or puncturing it. 
         [0058]      FIG. 11  depicts the use of a thermally insulated inner liner  102  sized to fit into a common receptacle, a tall kitchen garbage can  100 . The kitchen garbage can liner  102  is received in the garbage can  100 , and its flaps  104 ,  106  are folded down and secured to one another at points  108 ,  110 . Similar to the five gallon bucket insulated liner, the kitchen garbage can liner  102  has flaps  104 ,  106  that extend a substantial length down the sides of receptacle  100  to disguise and camouflage the nature of the receptacle  100 . 
         [0059]      FIG. 12  is a depiction of the use of a thermally insulated inner liner sized to fit into a large garbage can  200 , the garbage can liner  202  being sized to fit in the garbage can  200 , while still having relief cuts  204 ,  206  that allow the inner liner to be engaged in the garbage can without interfering with access to the handles on the garbage can. Similar to the five gallon bucket insulated liner, the large garbage can liner  202  has flaps  204 ,  206  that extend a substantial length down the sides of receptacle  200  to disguise and camouflage the nature of the receptacle  200 . 
         [0060]    In each of the preferred embodiments, as illustrated generally at  FIG. 13 , the exterior side of the downwardly depending flaps  32 ,  34 ,  104 ,  106 ,  204 ,  206  is provided such that they can imprinted, embossed, engraved or embroidered to display logos, insignias, indicia and emblems. In a preferred embodiment of the present invention, the upper portion of the inner sleeve comprises the exterior side of the downwardly depending flap when the liner  12 ,  102 ,  202  is secured in a receptacle, and is constructed from a material onto which logos, insignias, indicia and emblems may be applied and displayed. It is also contemplated within the principles of the present invention that the downwardly depending flaps may be provided with hook and loop fasteners to receive panels with coordinated hook and loop fasteners, the panels having logos, insignias, indicia and emblems applied thereon. 
         [0061]    The collapsible liners  12 ,  102 ,  202  disclosed herein provide a highly portable cooler that takes advantage of being used in conjunction with commonly available hard shell receptacles such as, for example and without limitation, a five gallon bucket, a tall kitchen garbage can and a large garbage can. The liners  12 ,  102 ,  202  are constructed from layers of pliable materials and may be collapsed for transport and then erected at the point of use and secured to the common receptacle available. The liners  12 ,  102 ,  202  add to the festivities of the occasion by allowing users to display logos, insignias, emblems or other indicia on the sizable downwardly depending flaps  32 ,  34 ,  104 ,  106 ,  204 ,  206  that are provided in alternative embodiments as a printable surface on the outwardly facing exterior panel when the liner is erected in a receptacle, or by providing means for securing a panel or placard having a logo or team represented thereon to the flaps  32 ,  34 ,  104 ,  106 ,  204 ,  206 . For example, and without limitation, an appropriately sized panel  400  is removably secured to a flap  402  using a means for securing thereto. In a preferred embodiment of the present invention, the panel  400  is secured through the use of hook connector strips  404  affixed to the panel  400  and loop connector strips  406  affixed to the panel  402 . Other devices for removably securing the panel  400  to the flap  402  are contemplated, including without limitation button snaps, zippers, magnets and other devices providing for temporary adhesion between the panel  402  and flap  400 .
