     FIELD 
     The exemplary embodiments relate generally to a modular ice barrel that is shipped in component form and minimizes shipping volume. Once the ice barrel is delivered to the final destination, individuals can expediently assemble the components. As a result of the reduced volume and assembly capability, shipping and transportation costs are minimized and greater amounts of ice barrels delivered in a single shipment can be increased. 
     BACKGROUND 
     Ice barrels can be shipped fully assembled to the point of use from a distant location. This can result in empty space in the interior cavity of the barrel to be shipped along with the fully assembled barrel. An example shipping container may be roughly 24 inches by 24 inches by 24 inches with a total volume capacity of roughly 13,824 cubic inches. Assembled ice barrels can exceed the volume capacity of a standard shipping container. As a result of wasted space and size limitations, the cost of shipping a fully assembled barrel may be greater than the cost of the barrel itself. Although injection molding can be used in conjunction with the examples disclosed herein, injection molded components may add to the weight of the barrel adding to the cost of shipment. Also when turning over a heavier weight barrel to empty water and ice from the interior cavity, in certain instances may lead to injury due to the weight of the barrel. 
     SUMMARY 
     An example portable ice barrel may include one or more of an exterior barrel wall, an interior barrel wall, and insulative layer positioned in between the exterior barrel wall and the interior barrel wall. In one example, the interior barrel wall can comprise an expandable bladder made of flexible material and the expandable bladder can have an open end, a closed end, and can be adapted to expand from a collapsed position into an expanded position. In the collapsed position, the bladder can be folded into a compact position to reduce the volume of the interior of the bladder to minimize shipping volume. Other components of the example portable ice barrel such as the lid, top rim, bottom rim, and base may also incorporate living hinges to allow the components to be collapsed further reducing the shipping volume. 
     In another example, a portable ice barrel can include a plurality of sections which can be configured to form a cylindrical insulation layer. The cylindrical insulation layer can form an opening and an inner liner can extend into the opening of the cylindrical insulation layer to form an interior barrel cavity for receiving ice and the desired contents. In one example, the plurality of sections can be disassembled to minimize the shipping volume. 
     In yet another example, a portable ice barrel may include one or more of an exterior barrel wall, an interior barrel wall, and insulative layer positioned in between the exterior barrel wall and the interior barrel wall. The interior barrel wall can comprise an expandable bladder made of flexible material and the expandable bladder can have an open end, a closed end, and can be adapted to expand from a collapsed position into an expanded position. In the collapsed position, the bladder can be folded into a compact position to reduce the volume of the interior of the bladder to minimize shipping volume. After assembly of the individual components, insulative material can be injected into a gap between the exterior wall inside surface and the bladder exterior surface to form an insulative layer there between.

     DETAILED DESCRIPTION 
     In the following description of the various examples and components of this disclosure, reference is made to the accompanying drawings, which form a part hereof, and in which are shown by way of illustration various example structures and environments in which aspects of the disclosure may be practiced. It is to be understood that other structures and environments may be utilized and that structural and functional modifications may be made from the specifically described structures and methods without departing from the scope of the present disclosure. 
     Also, while the terms “front,” “back,” “rear,” “side,” “forward,” “rearward,” “backward,” “height,” “width,” “length,” “volume,” and the like may be used in this specification to describe various example features and elements of the invention, these terms are used herein as a matter of convenience, e.g., based on the example orientations shown in the figures and/or the orientations in typical use. Nothing in this specification should be construed as requiring a specific three dimensional or spatial orientation of structures in order to fall within the scope of the disclosure. 
     Referring to  FIGS. 1-8 , in an embodiment, a portable ice barrel  1  can include an exterior barrel wall  2 , an interior barrel wall  3 , and insulative material  4  positioned in between the exterior barrel wall  2  and the interior barrel wall  3 . The interior barrel wall  3  can be an expandable bladder  3  made of a flexible material. Example flexible materials include but are not limited to flexible plastics, including flexible polyvinyl chloride (PVC) films. In an embodiment, the expandable bladder may be configured to expand from a collapsed position into an expanded position. For example, in the collapsed position, the bladder can be folded into a compact position to reduce the volume of the interior of the bladder. In an example embodiment, in the collapsed position, the expandable bladder can resemble a folded bag. In addition, for example, in the expanded position, the bladder can be expanded to define a cavity of increased volume within the interior of the bladder. The expandable bladder can include an open end  5  and a closed end  6  and a bladder body segment  15  extending between the open end and the closed end. The expandable bladder can include a bladder interior surface  16  and a bladder exterior surface  17 . In an embodiment, the expandable bladder can include a top drape  18  extending from a perimeter of the open end. The top drape can be configured to fold toward the exterior surface  17  proximate the open end. 
     In an embodiment, the expandable bladder can be configured in the expanded position within the exterior barrel wall  2  to define an interior barrel cavity  10  such that the closed end of the bladder can contain ice within the barrel cavity and the open end allows access to the barrel cavity. For example, the open end of the expandable bladder can be secured proximate to a top edge of the exterior wall  2 , and the body segment of the expandable bladder can be positioned within the exterior barrel wall  2 . In an example embodiment, the body segment of the expandable bladder can be cylindrical in shape when the expandable bladder is in the expanded position. In one example, an inner diameter of the body segment can be between about 18 inches to about 24 inches. In another example, a diameter of the exterior wall can be about 1 inch to about 5 inches greater than the diameter of the body segment of the expandable bladder. 
     In one example, the exterior barrel wall  2  includes an exterior wall outside surface  11 , an exterior wall inside surface  12 , an exterior wall top edge  13 , and an exterior wall bottom edge  14 . In an embodiment, the exterior barrel wall  2  is constructed of a semi-rigid material. Example semi-rigid materials include but are not limited to styrene, polyethylene, and vinyl. In one example, the exterior wall outside surface can be suitable for printing thereon. The exterior barrel wall can provide structural support for the interior barrel wall and/or the insulative material. In an embodiment, the exterior barrel wall can be constructed of, for example, a flexible sheet made of semi-rigid material. Example flexible sheets made of semi-rigid material include, for example, styrene sheet, polyethylene sheet, and vinyl sheet. The flexible sheet of rigid material can be flexed into the desired shape of the exterior barrel wall so that a sheet outside surface  11 , sheet inside surface  12 , sheet top edge  13 , and sheet bottom edge  14  become the exterior wall outside surface  11 , the exterior wall inside surface  12 , the exterior wall top edge  13 , and the exterior wall bottom edge  14  of the exterior barrel wall  2 . For example, a sheet right side edge  29  can be folded over a sheet left side edge  30 , or vice versa, and secured at a seam  31  to form a cylinder. Example shapes of the exterior barrel wall include cylindrical, rectangular, and oval. 
     In an embodiment, the insulative material can be a foam material, including for example rigid expanded polystyrene foam material. In an embodiment, the insulative material can provide structural support for the exterior barrel wall and or the interior barrel wall. In and embodiment, the insulative material can have an R-value of at least 5. In an embodiment, the insulative material can be injected into a gap  32  between the exterior wall inside surface and the bladder exterior surface to form an insulative layer  4  there between. 
     In an embodiment, the portable ice barrel can include a top rim  19  secured to the exterior wall top edge. In an embodiment, the top rim can include a top rim channel  20  defined within the top rim. In an embodiment, the top rim can include rim cones  21  positioned in the rim channel. In an embodiment, the rim cones can be spaced an equal distance from each other within the rim channel. In an embodiment, at least a portion of the top drape  18  of the expandable bladder is draped over a portion of the exterior wall top edge and the top rim is positioned such that the portion of the top drape and the portion of the exterior wall top edge are within the top rim channel so that the top rim channel creates a friction fit holding the top drape in position against the exterior wall top edge. 
     In an embodiment, the portable ice barrel can include a bottom rim  22  secured to the exterior wall bottom edge  14 . In an embodiment, the bottom rim can include a bottom rim channel  23  defined within the bottom rim. In an embodiment, the bottom rim can include rim cones  21  positioned in the bottom rim channel. In an embodiment, the rim cones can be spaced an equal distance from each other within the bottom rim channel. In an embodiment, at least a portion of the exterior wall bottom edge is positioned within the bottom rim channel to create a friction fit between the bottom rim and the exterior wall bottom edge to hold the bottom rim in position against the exterior barrel wall. 
     In an embodiment, the expandable bladder includes a drain pipe  7  secured proximate the closed end of the bladder  3 . The drain pipe can include a proximal end  8  and a distal end  9 . The drain pipe proximal end can be secured to the closed end of the expandable bladder. In an embodiment, the drain pipe can be constructed of a plastic material and the proximal end  8  can be secured to the expandable bladder by a suitable plastic welding technique. For example, the drain pipe can be constructed of rigid PVC and welded to the bladder by high frequency welding, including radio frequency heat sealing. In an embodiment, the drain pipe is configured such that the drain pipe distal end extends through the exterior barrel wall. In an embodiment, a drain pipe valve can be secured to the distal end of the drain pipe. Example drain pipe valves can include a one-way check valve or a ball valve. 
     In an embodiment, the portable ice barrel includes a lid  24  configured to removably cover the interior barrel cavity. In an embodiment, the lid can include a lid hinge  27  and lid handle  28 . In an embodiment, the lid handle is a hold defined in the lid  27 . The lid can be constructed of, for example, clarified polypropylene or PEGT. In an embodiment, the portable ice barrel can include a sign holder  25  and a sign holder extrusion  26  configured to hold a sign. In an embodiment, as depicted in  FIG. 7 , the sign holder extrusion  26  is in the form of a clamp. In an embodiment, the portable ice barrel includes a barrel base and casters (not shown). In an embodiment, the barrel base is in the form of a tray on which the bottom of the portable ice barrel can be placed. The barrel base can be the same shape as the portable ice barrel. In an embodiment, casters are secured to the underside of the barrel base to facilitate moving the portable ice barrel by pushing the barrel while it is positioned on the barrel base. In another embodiment, the casters are secured to a collapsible barrel cooler bottom rim with a living hinge by a plurality of support tubes. 
     The portable ice barrel of the instant disclosure can be assembled according to various methods including steps and components disclosed herein. In an embodiment, a barrel form  31  is used to assemble the portable ice barrel of the current disclosure. In an embodiment, the barrel form  31  is shaped in the shape desired for the interior barrel cavity  10 . In an embodiment, the expandable bladder can take the shape of the barrel form  31  when the bladder is expanded and positioned over the form  31  to cover the form  31  with the interior surface of the bladder. In an embodiment, the open end of the expandable bladder is expanded and placed over the barrel form as depicted in  FIG. 8A . In an embodiment, the bladder is pulled down over the form so that the bladder open end is positioned proximate the form open end  33  and the bladder closed end is positioned proximate the form closed end  34 , such as shown by example in  FIG. 8C . 
     In an embodiment, a top rim is positioned over the barrel form  31  so that the top rim encircles the form  31 . In another embodiment, a collapsible top rim with a living hinge is positioned over a collapsible heat stake plate with a living hinge. In an embodiment, the bladder top drape  18  is positioned in the top rim channel  20  so that a portion of the top drape covers a portion of the inside surface of the top rim channel  20 , such as shown by example in  FIG. 8C . In an embodiment, an exterior barrel wall  2  can be positioned around the expandable bladder  3  covering the barrel form  31  so that a gap  32  is defined in between an inside surface  12  of the exterior barrel and the bladder exterior surface  17 . In an embodiment, the exterior barrel wall can be formed by flexing and welding a flexible sheet as described above before the exterior barrel wall is positioned around the interior barrel wall. In addition, in an embodiment, the logos and/or graphics can be printed on the outside surface of the sheet prior to forming the sheet into the exterior barrel wall. In an embodiment, the exterior wall top edge  13  is positioned in the top rim channel and in contact with a portion of the top drape of the expandable bladder which is also positioned in the top rim channel so as to form a friction fit seal between the top drape  18  and exterior wall top edge  13 . In an embodiment, an adhesive can be used to adhere the top drape of the bladder to the top rim channel and/or adhere the exterior wall top edge to the top drape of the expandable bladder. In an embodiment, the distal end of the drain pipe can be positioned to extend through a hole defined in the exterior wall. In an embodiment, a bottom rim can be positioned over the exterior wall bottom edge, such as shown by example in  FIG. 8C . In an embodiment, the dimensions of the exterior barrel wall  2  and the interior barrel wall  3  can be configured so that the gap  32  defined in between the exterior wall inside surface  12  and the bladder exterior surface  17  can be about 1 inch to about 5 inches. In an embodiment, insulative material is inserted into the gap through the bottom of the barrel to form the insulative layer  4 . In an embodiment, the insulative layer covers the bladder body segment. In an embodiment, the insulative layer covers the bladder exterior surface at the closed end of the bladder. In an embodiment, once the insulative layer is in place or cures, the barrel form can be removed to expose interior barrel cavity. In an embodiment, the portable ice barrel is rotated from an upside-down position shown in  FIG. 8C  into an upright position shown in  FIG. 8D  before the barrel form is removed from the interior barrel cavity. In an embodiment, the lid, sign holder, and sign extrusion can be secured to the top rim. In an embodiment, casters can be secured to the underside of a barrel base and the portable ice barrel can be positioned onto the barrel base. In another embodiment, the casters are secured to a collapsible barrel cooler bottom rim with a living hinge by a plurality of support tubes. 
       FIGS. 9-14E  depict another example portable ice barrel  101 . The portable ice barrel  101  can include similar components as the example depicted in  FIGS. 1-8 . These components are labeled with like reference numerals in the accompanying drawings but use 100 series reference numerals. In the example shown in  FIGS. 9-14F , instead of using insulative material  4 , a series of barrel sections or baffles  104 , as shown in  FIG. 11 , are used to provide insulation to the contents of the portable ice barrel  101 . In another example, as shown in  FIG. 15 , an outer and inner layer form a gap of air that provides insulation to the contents of the portable ice barrel  101 .  FIG. 9  shows a top perspective view of the example portable ice barrel  101 , and  FIG. 10  shows a side perspective view. The exterior of the portable ice barrel  101  generally includes a top wall  135 , a lid  124 , a drain pipe  107 , an exterior barrel wall  103 , and a bottom rim  122  which can be configured to receive a series of wheels  137 . The exterior barrel wall  103  can be formed as a graphic panel and can include any name, logo, or symbol depending on the contents and desired advertising. The top wall  135  can have a partial rim  119  and can be configured to receive a lid  124 . The lid  124  provides an opening into the interior barrel cavity  110  formed in the portable ice barrel  101 , and can be hingedly connected to the top wall  135  by hinge  127 . The lid  124  may also include a handle  128 , which can be in the form of a projection for opening the lid  124 . Additionally the top wall  135  can be formed with a notch  128   a  for receiving the handle  128  of the lid  124 . In one example, the lid  124  can be provided with a living hinge (not shown) that separates the lid  124  into two sections such that the lid  124  can be folded into a smaller configuration for easy and compact shipment. 
       FIG. 11  depicts an exploded perspective view of the portable ice barrel  101  showing both the exterior and interior components of the portable ice barrel  101 . In addition to the exterior components described above, the example portable ice barrel  101  can include an insulation layer  160  formed of barrel sections  104 , a bladder or liner  102 , and a base assembly  136  Like in the example shown in  FIGS. 1-8 , the liner  102  forms an interior barrel cavity  110  for receiving contents, such as ice and any desired products. 
     As shown in  FIG. 11 , the barrel sections  104  are configured to fit under the top wall  135  and between the exterior barrel wall and the liner  102 . The barrel sections  104  can each be formed identically. As will be described in further detail below, the barrel sections  104  form the cylindrical insulation layer  160  by trapping air between the liner  102  and the exterior barrel wall  103 . 
     In this example, six barrel sections  104  can be provided. In one example, each of the barrel sections  104  can comprise  30  degrees of the cylinder forming the portable ice barrel  101 . However, any number of sections can be provided for the desired insulation and manufacturability. The barrel sections  104  can be provided with a slight curvature such that they form a cylinder when assembled in the portable ice barrel  101 . The curvature can be slight enough such that the barrel sections  104  can be shipped in a mostly flat configuration. 
       FIGS. 12A-12D  depict perspective side and top views of the portable ice barrel  101  before attachment of the exterior barrier wall  103  onto the portable ice barrel  101 . As shown in  FIGS. 11-12D , the outermost surfaces of the barrel sections  104  can be formed with a series of fins  142 . When the portable ice barrel  101  is assembled, the fins  142  extend from an outermost wall forming the barrel sections  104  to the exterior barrier wall  103 . The fins  142  are configured to trap air between the exterior barrier wall  103  and the liner  102 . Air is generally a good thermal insulator, and helps to slow outside or ambient temperatures from melting the ice or warming the contents stored in the interior barrel cavity  110 . Alternatively, the fins  142  trap air to help prevent heat from escaping the interior barrel cavity  110  should it be desired to store warm contents. In this way, the barrel sections  104  provide thermal insulation to the liner  102  and the contents stored therein. 
       FIGS. 13A-13F  show partially formed barrel sections  104  to illustrate an example connection method for securing the barrel sections  104  together. As shown in  FIGS. 13A-13F , the barrel sections  104  can be provided with tongue and groove type connections  148 . In particular, each side of the barrel sections  104  can be provided with either a tongue  149  or a groove  150 . The tongue  149  can be formed of two L-shaped legs  151  that project outwardly. The L-shaped legs  151  of the tongue  149  can be formed of a thin plastic material such that the legs have a degree of resiliency. Additionally, the groove can be defined by two facing L-shaped legs  152  and a resilient V-shaped projection  153 . The legs  151  can be configured to resiliently extend into the groove  150  such that when the legs  151  of the tongue  149  are placed into contact with the groove  150 , the L-shaped legs  151  contact the L-shaped legs  152  causing the L-shaped legs  151  to resiliently bias against the L-shaped legs  152 . As shown in  FIG. 13D  to secure the barrel sections  140  together the tongue  149  is aligned with the groove  150  such that the legs  151  extend into the groove  150 . Once the L-shaped legs  151  are placed into contact with the L-shaped legs  152 , the barrel sections  140  are held together securely in both a vertical and horizontal direction. It is contemplated that the barrel sections  104  can be secured together using any known connection method such as removable fasteners, adhesives, snap-fit, etc. 
     As shown in  FIGS. 13F-13I , once the barrel sections  104  are secured together, the L-shaped legs  151 , the L-shaped legs  152 , and the V-shaped projection  153  also define a recess for receiving a push-in clip  146  located on a top wall section to secure the top wall  135  to the top of the barrel sections  104 . As depicted in  FIG. 13F , the push-in clip  146  can be a Christmas tree-type clip. As shown in  FIG. 13F , the clips  146  are installed through a hole  158  in the top wall  135 . The clips  146  can be provided with resilient ribs, which extend along the length of the shaft of the clips  146 . When the push-in clips  146  are engaged with the recess formed by the L-shaped legs  151 , the L-shaped legs  152 , and the V-shaped channel, the ribs located on the shaft of the clips  146  maintain the top wall  135  on the barrel sections  104 . In this way, the clip  146  can be designed as a one way, press fit application such that once installed, the clips  146  are extremely difficult to remove to secure the top wall  135  to the insulation layer  160 . The clips  146  can be configured to require no turning of a screw or fastener, which reduces the amount of labor to assemble the portable ice barrel. 
       FIGS. 14A-14E  illustrate partially formed bottom sections of the barrel sections  104  to illustrate a method of connecting the bottom rim  122  to the barrel sections  104 . As shown in  FIGS. 14A-14E , the bottom rim  122  can be provided with a resilient locking tab  154  for securing the bottom rim  122  to the barrel sections  104  without the use of tools. In particular, the bottom rim  122  can be provided with an opening  156 , which provides a cutout for the locking tab  154  to flex. The barrel sections  104  can be provided with a corresponding opening  157  for receiving the locking tab  154 . Once the bottom rim  122  is placed into contact with the barrel sections  104 , the locking tab  154  flexes within the opening  156  and into the corresponding opening  157  to secure the bottom rim  122  to the barrel sections  104 . As shown in  FIG. 14A , the locking tab  154  can be provided with a ramp  154 A, which permits the locking tab to move outwardly when the bottom rim  122  is placed into contact with the barrel sections  144 A- 144 F. Once the locking tab  154  is aligned with the opening  157  the resiliency of the tab moves the ramp  154 A inwardly into the opening  157  to secure the bottom rim  122  to the barrel sections  104 . 
     The liner  102  can be formed of a similar liner material as the example shown in  FIGS. 1-8 . Additionally, as shown in  FIGS. 11, 15, and 13A , a series of clips  140  can be used to support the liner  102  inside the portable ice barrel  101 . In particular, the liner  102  can be held in place onto the insulation layer  160  by a series of clips  140 . The clips  140  can be formed U-shaped such that the clips  140  can extend over the rim of the insulation layer  160  and the liner  102  to securely hold the liner  102  into place in the portable ice barrel  101 . 
     In one example, the top wall  135  can be formed of sections. As shown in  FIGS. 13G and 13E , the sections can make up the hinge  127  for receiving the lid  124 . Although not shown, the sections can also form the partial rim  119 , and can be secured to the sections forming the hinge  127  using any known method. As discussed above, the top wall  135  can be secured to the barrel sections  104  using a push-in clip  146 . 
     The base assembly  136  can be formed of a support disc  138 , a series of supports  139 A- 139 D to form a grid  139 , the bottom rim  122 , and wheels  137 . As shown in  FIG. 14C , the bottom rim  122  can be formed with a wheel mount or projection  162  for receiving the wheels  137 .

As shown in  FIG. 11  each support  139 A- 139 D can be provided with a series of slits  143  for receiving a respective slit  143  on a corresponding support grid  139 . Therefore, the grid  139  can be assembled quickly by aligning the slits  143  on the supports  139 A-D. Although in this example four supports are provided, the grid  139  can be provided with two or more supports depending on the size and desired strength of the base assembly. The supports  139 A- 139 D can be formed of any known and suitable material and in one example can be formed of a plastic material, cardboard, or other like material. In another embodiment, the base assembly can be formed by a single collapsible bottom rim that incorporates a living hinge. The casters are secured to a collapsible barrel bottom rim by a plurality of support tubes. 
     The drain pipe  107  can be formed similar to drain pipe  7  and extends from an interior of the portable ice barrel  101  to the exterior to provide for an outlet for ice water. In one example, the drain pipe  107  can be built into the liner  102 . Additionally, one of the barrel sections  104  can be provided with a die cut hole for receiving the drain pipe  107  there through. 
     To assemble the portable ice barrel, the barrel sections  104  can be connected to one another using the tongue and groove connection as described above. The base  136  can then be assembled by forming the supports  139 A- 139 D into a grid  139 . The disc  138  and the support grid  139  can then be placed inside the insulation layer  160  formed by the barrel sections  140 . The disc  138  and the support grid  139  can then be held in the barrel sections  140  by securing the base rim  122  to the barrel sections  104 . The wheels  137  can then be placed on the base rim  122 , and can be held into place on the base rim  122  via a snap fit. The base rim  122  can be secured to the barrel sections  104  by aligning the tabs  154  with the holes  157 . As shown in  FIG. 13A  the liner  102  can be pulled or stretched over the insulation layer and held into place by the clips  140 . The top wall  135  and partial top rim  119  can then be assembled, and the lid  124  can be secured to the top wall  135 . Once the top wall  135  is formed, the top wall  135  can be secured to the top of the barrel sections  104  by the clips  146 . The top wall  135  and top rim  119  also secure the liner  102  by a press fit between the top rim  119  and the barrel sections  104 . Finally the exterior barrel wall  103  can be printed and then placed around and secured to the barrel sections  104 . 
       FIGS. 15A-15F  depict another example portable ice barrel  201 , where like reference numerals refer to the same or similar elements in all of the various views but include 200 series reference numerals. The example shown in  FIGS. 15A-15F  is similar to the example shown in  FIGS. 9-14E , however this example implements an optional exterior liner  204  instead of barrel sections. The example shown in  FIGS. 15A-15F  also has a different base assembly  236 , but the base disclosed in relation to the example discussed in relation to  FIGS. 9-14E  can optionally be used in conjunction with this example. 
       FIG. 15A  shows an exploded view of the example portable ice barrel  201 . The example portable ice barrel  201  can include lid  224 , which can incorporate living hinges  215 A to allow the lid to be folded for compact shipment or storage. Similar to the example shown above in  FIGS. 9-14E , an insulation layer may be formed by trapping air between the interior liner  202  and the exterior barrel wall  203 . Like in the example shown in  FIGS. 1-8 and 9-14 , the liner  202  forms an interior barrel cavity  210  for receiving contents, such as ice and any desired products. The interior liner  202  can be configured to be collapsible such that it can be packed efficiently during shipment. Fasteners, hole plugs, or clips  240  can be included to secure the top rim  235  to the interior liner  202  and an optional collapsible heat stake plate  206 .

The tops and bottoms of inner liner  202 , outer liner  204 , and exterior wall  203  all include various slots or holes  241  to facilitate the securing of the structures to each other by various types of fasteners. In another example of the portable ice barrel  201 , bottom rim  222  and bottom rim  122  discussed above may include a bottom rim channel defined in the bottom of the rim that attaches by tongue and groove to the bottom edge of the exterior wall  203  which can include a tongue and groove type fitting that secures to the bottom rim  122  or optional bottom rim  222 . Bottom rim  122  and bottom rim  222  may include living hinges  215 B to allow the structure to be folded to decrease shipping volume.  FIG. 15E  depicts a top view of the bottom rim  222 . Collapsible bottom rim  222  incorporates a living hinge  215 B and slots or holes  241  for receiving a series of suitable fasteners. In one example, the bottom rim  222  is secured via fasteners to the bottom of inner liner  202 , outer liner  204 , and exterior wall  203  through the various slots or holes  241 .  FIG. 15F  depicts the bottom rim  222 . As shown in  FIG. 15F , the bottom rim  122  can be provided with support tube projections  218 . During assembly of the portable cooler  201 , the support tubes  208  can be placed over the support tube projections  218 . 
       FIG. 16  shows an example container that can be used to ship or store the portable cooler examples discussed herein. The portable cooler examples discussed here can be configured to be easily collapsible to fit in a much smaller sized container than traditional ice barrels. The container can define a length, a height, and a width. The width of the container can be less than a diameter of the assembled portable ice barrel. In one example, the ratio of the width of the container to the diameter of the assembled portable ice barrel can range from 1 to 5 to 1 to 3. In another example, the ratio of the width of the container to the diameter of the assembled portable ice barrel can range from 1 to 10 to 1 to 2. In the example container, the height is greater than the length, and the length is greater than the width. The components of the portable ice barrel can be shipped in a container having a predominately flat configuration such that the portable ice barrel can be shipped and assembled at the receiving end. In one example, the portable ice barrel can be packaged in a 34″ by 24″ by 12″ box having volumetric capacity of 9792 cubic inches. In one example, the portable ice barrel can be packaged in a 32″ by 24″ by 8″ box having volumetric capacity of 6144 cubic inches. In one example, the portable ice barrel can be packaged in a 34″ by 14″ by 8″ box having volumetric capacity of 3808 cubic inches. 
     In one example, the volumetric capacity of the inner liner of the cooler can be 6295 cubic inches for storing the desired contents. In one example, a ratio of the volumetric storage capacity of the inner liner of the portable cooler to the volume of the container can be between 1.5:1 to 4:1. 
     In another example, the individual components can be shipped separately in individualized containers. The individual components can then be reassembled at the final destination or combined with other units to form complete kits and sold at retail outlets. 
       FIGS. 17A-17O  depict another example insulating device or container  301 , where like reference numerals refer to the same or similar elements in all of the various views but include 300 series reference numerals. The example shown in  FIGS. 17A-17F  is similar to the example shown in  FIGS. 15A-15F ; however, this example implements a series of structural wires or rods  305  for structural support of the insulating device  301  in addition to other variations that will be discussed below. The example insulating device  301  can be configured to be a portable and collapsible cooler similar to the above examples. In one example, the insulating device  301  can fit into a 20 in. by 6 in. by 40 in. box for shipment, and the insulating device  301  can have volumes similar to the volumes discussed in relation to the other examples discussed herein. The example insulating device  301  can include a base  336 , an exterior wall  303 , an interior bladder or liner  302 , a liner rim  306  for securing and retaining the liner  302 , a lid  324 , an exterior liner  304 , and a top rim  335 . 
     In this example, the base  336  can be formed of a bottom plate  322 , casters  337  having wheels, and supports  308 .  FIGS. 17B-17D  show further detail of the bottom plate  322 , where  FIG. 17B  is a top perspective view,  FIG. 17C  is a side view, and  FIG. 17D  is a bottom perspective view. As shown in  FIG. 17B , the bottom plate  322  can include a series of openings  319  for receiving supports  308 , which can be in the form of tubes or cylinders. The supports  308  are configured to support the bottom of the inner liner  302  when the inner liner  302  is filed, for example, with ice, beverages, or other contents. The supports  308  can thus transfer all of the weight of the inner liner  302  contents to the bottom plate  322  of the insulating device  301 . In alternative examples, a single support can be provided or the support can be in the form of a frame that is configured to support the weight of ice and other contents that will be stored in the insulating device  301 . The supports may also be telescopically arranged on the base, such that the supports are configured to extend outward during the assembly of the insulating device  301 . 
     The bottom plate  322  may also include one or more indicators  321  to indicate to the user the orientation of the inner liner  302 , the exterior liner  304 , and the rods  305 . For example, as shown in  FIG. 17B , arrows can direct the user to the back of the insulating device  301  and notches or inserts  366  located in the bottom plate  322  for assembling the insulating device  301 . The series of inserts or notches  366  on the bottom plate  322  are configured to receive the rods  305 . In particular, the inserts  366  are configured to receive the ends  380   a,    380   b  of the wire rods  305 . The inserts  366  can also include a ramp surface that is configured to engage the end of the wire rod  305 . The ramp surface is provided with an angled surface such that when the end of the wire rod  305  engages the notch, the rod  305  can be pushed along the angled surface and held into place by the ramp surface. The rods  305  may also be held into place on the bottom plate  322  with slots. Other connections between the rods  305  and the bottom plate  322  are also contemplated. For example, one or more of a threaded, ball and socket, or bayonet connections are also contemplated. 
     Additionally,  FIG. 17C  shows a side view of the bottom plate  322 . Because the exterior wall  303  is placed onto the insulating device last, the exterior liner  304  may interfere with the placement of the exterior wall  303  over the rim  335 . Specifically, the exterior liner  304  may prevent the user from positioning the exterior wall  303  at a sufficient angle with respect to the rim  335  to allow the exterior wall  303  to be placed within the rim. The bottom plate  322  can, therefore, be provided with an angled or beveled rim  355 , which helps assist in the assembly of the exterior wall  303 . In particular, the angled rim  355  provides a higher point to which the exterior wall  303  can be placed over the bottom plate  322  first and then subsequently flexed around the lower points of the angled portion of the rim  355 . When the exterior wall  303  is installed over the exterior liner  304 , the bottom portion of the exterior wall  303  can be positioned within the bottom plate  322  over the angled rim  355 . Once the exterior wall  303  is installed, the angled rim  355  holds the exterior wall  303  into place. 
     The casters  337  are configured to attach to the bottom plate  322  via an interference fit or snap fit connection to allow for an easy assembly. Specifically, as shown in  FIG. 17D , which is a bottom view of the base plate  322 , holes  359  can be provided in the bottom plate  322  for receiving the casters  337 . The holes  359  can be dimensioned such that the casters  337  fit within the holes  359  by way of an interference fit. However, other types of connection methods are contemplated for securing the casters  337  to the bottom plate  322 . For example, the casters could be connected to the bottom plate  322  by a threaded connection, a ball and socket connection, or a bayonet connection as well as other types of known connections in the art. 
     The exterior wall  303  is shown in  FIG. 17E . The exterior wall  303  can be formed in as a rectangular sheet of material that is configured to roll up into a cylinder, by, for example, adding an adhesive to the strip or area  365  or by way of mechanical fastener and securing the area  365  to the opposite end. In this way, the exterior wall  303  can be formed of a flexible material such that the exterior wall  303  can be easy rolled up into a cylinder shape and can be flexed and collapsed into a smaller volume container for shipment. The exterior wall  303  can include holes  361 , which when aligned, receive a drain pipe or tube  307 . Additionally, the exterior wall  303  can include one or more notches  363  for aligning the exterior barrel wall with the bottom plate  322 . Specifically, the notches  363  can align with the projections  366  on the bottom plate  322 . The wall  303  may also include a graphic area  364  for printing any desired graphics, for example, a brand label, advertisement, price, logo, announcement, etc. It is also contemplated that the exterior wall  303  may also be extruded of a flexible material such that the exterior wall may be collapsible for shipment purposes. 
       FIG. 17F  shows an exploded view of the inner liner  302  and the liner rim  306 . As shown in  FIGS. 17F and 17G , the inner liner  302  can be formed in a cylindrical shape. The inner liner  302  can be formed of a flexible plastic material that is substantially waterproof such that when ice is placed in the inner liner  302  water from the ice does not leak out of the inner liner  302 . A layer of insulation material  367  can be placed on the bottom area of the inner liner  302  on the outside surface or on the inside surface of the inner liner  302  to help maintain the temperature of the inside of the inner liner  302 . Additionally, insulation material can be placed at other areas along the inner liner  302  to help to maintain the temperature of the contents within the inner liner  302 . The inner liner  302  may include a drain or an opening in the bottom of the inner liner  302 , which can be connected to a drain pipe  307 . A drain plug  384 , as shown in FIG.  17 F 1 , can be placed into the drain pipe  307  for selectively opening the drain pipe  307  to selectively control the water from the melted ice exiting the insulating device  301 . The drain plug  384  can include a series of concentric rings  385  that are placed axially along a shaft of the drain plug  384 . The drain plug  384  can also include a dome-shaped head  386 , which includes a handle  386   a  and a series of axially extending ridges  387 , which are configured to engage the exterior liner  304  and the exterior wall  303  to maintain the drain plug  384  in place on the outside of the insulating device  301 . 
       FIG. 17F  also illustrates how the inner liner  302  can be connected to the liner rim  306 . In one example, the inner liner  302  can be connected to the liner rim  306  by heat staking. Specifically, several flanges  370  of the inner liner  302  that project outwardly from the top of the inner liner  302  can be sandwiched between the liner rim  306  and a series of strips  371 , which form a circle around the inner liner  302 . The flanges  370  can also include openings  372  that receive corresponding projections  373  in the strips  371 . The projections  373  of the strips  371  are received in corresponding openings  374  in the liner rim  306 . Each of the projections  373  can then be heated such that they deform to connect the inner liner  302  to the liner rim  306 . Other techniques are contemplated for securing the inner liner  302  to the liner rim  306 . For example, fasteners may be used in the place of the projections  373  and the heat staking method. In other examples, one or more of clips, ties, or straps as well as the other examples discussed herein could be used to secure the inner liner  302  to the liner rim  306 . 
       FIG. 17G  shows a top view of the liner rim  306 . The liner rim  306  also includes notches  375  for receiving and securing the ends of the wires or rods  305 . Additionally, liner rim  306  includes a series of slots  376  for receiving locking tabs  369  of the top rim  335 . The slots  376  may also include a corresponding pin or engagement member for maintaining the locking tabs within the slots  376 . The liner rim  306  can also include a pair of knuckles  377 , which receive integral pins  378  on the lid  324  to form part of a hinge for the lid  324 . 
     The top rim  335 , which may also be referred to as a bezel, is shown in  FIGS. 17H and 17I .  FIG. 17H  shows a top view of the top rim  335 , and  FIG. 17I  shows a partial section of the top rim  335 . The top rim  335  secures around the perimeter of the top of the insulating device  301 , and generally provides a cover over the liner rim  306  of the inner liner  302 . As shown in  FIG. 17I , the top rim  335  can be provided with a series of locking tabs  369 . The locking tabs  369  can be located on the inner perimeter of the top rim  335 , and the locking tabs  369  can be configured to engage the slots  376  of the top rim  335 . As shown in  FIG. 17J , the locking tabs  369  can include an angled portion  369   a,  which can be configured to engage the underside of the slots  376  or an engagement member located within the slot  376  to help in securing the top rim  335  to the insulating device  301 . In other examples, the top rim  335  can be provided with one or more of threads, pin and slot connections, ball and socket, or bayonet connections for securing the top rim  335  to the insulating device  301 . 
     A top view of the lid  324  is shown in  FIG. 17K . The lid  324  can include two pins  378  which can be received in the knuckles  377  located in the liner rim  306 . In addition, the lid  324  can include an opening  379  for receiving a handle  388  such that the lid  324  can be easily lifted and rotated to retrieve the contents of the insulating device  301 . 
       FIG. 17L  shows a partial view of an example wire rod  305 . The example wire rod  305  can be secured between the liner rim  306  and the bottom plate  322 , and can be configured to prevent the expansion of the exterior liner  304 . An example wire rod  305  can include a first coin shaped end  380   a  and a second coin shaped end  380   b.  The first coin shaped end  380   a  is configured to fit in the notches  375  of the liner rim  306 , and the second coin shaped end  380   b  can be configured to fit in the notches  366  on the bottom plate  322 . Therefore, due to the size of the first coin shaped end  380   a  being slightly larger than the notches  375  of the liner rim and the second coin shaped end  380   b  being slightly larger than the notches on the bottom plate  322 , the wire rods  305  can be held in place on the insulating device  301 . 
     The exterior liner  304  is further illustrated in  FIGS. 17N and 17O . The exterior liner  304  can be formed of a rectangular sheet of material and in one example can be formed of a flexible and corrugated plastic material. Each end of the rectangular sheet can be secured together to form the exterior liner  304 , for example, by an adhesive or one or more mechanical fasteners. Once assembled, the material forming the exterior liner  304  can be configured to withstand compression forces in the axial direction. The exterior liner  304  can include insulation material  381 , which can be secured to the inside surface of the exterior liner  304  to provide insulation for the contents in the inner liner  302 . The upper perimeter and the lower perimeter of the exterior liner  304  can be provided with location notches  383 . The exterior liner  304  may also include a series of openings  389  for receiving the drain pipe  307  and plug  384  therein. It is also contemplated that the exterior liner  304  can be formed of an extruded piece of flexible material. 
     To assemble the insulating device  301 , the casters  337  can be secured to the base plate  322 , by placing the casters  337  into the holes  359  in the base plate  322 . With the wheels of the casters  337  on the floor, the exterior liner  304  can then be placed onto the base plate  322 . In one example, the exterior liner  304  can include indicators, e.g. numbers or letters, and the base plate  322  can include corresponding indicators  321 , such that the user can properly align the exterior liner  304  with the base plate  322 . The supports  308  can then be placed into the openings  319  of the base plate  322  for supporting the weight of the inner liner. The inner liner  302  can then be placed into the exterior liner  304 , by aligning the drain pipe  307  with the opening  382  in the exterior liner  304 . The wires or rods  305  can then be placed into the notches  375  of the liner rim  306  and then can be aligned with the inserts  366  of the base. The wires or rods  305  can then be locked into place by sliding the wires or rods  305  along each of the ramps formed on the inserts  366 .

     The example collapsible containers of the instant disclosure can provide for optimized shipping, use, and assembly of the portable ice barrel according to methods disclosed herein. For example, in an embodiment, components of the portable ice barrel are shipped to an assembly location located in the vicinity of the point of use. In an embodiment, a kit which includes the expandable bladder in the collapsed position is shipped to an assembly location. In an embodiment, the kit includes the expandable bladder in the collapsed position, the top rim, the bottom rim, the lid, the barrel base, and casters. In an embodiment, the assembly location includes flexible sheets with which to form the exterior barrel wall as described above. In an embodiment, the assembly location includes facilities to print graphics on the outside surface of the sheet as described above. In an embodiment, the assembly location can include the insulative material. In an embodiment, the assembly location includes a machine and material for injecting polystyrene foam during assembly of the portable ice barrel as described above. In an embodiment, the barrel form, flexible sheets, insulative material, and/or machine for injecting insulative material can be shipped to the assembly location. 
     The methods of shipping, use, and assembly disclosed herein provide several advantages over conventional methods used for conventional ice barrels. For example, conventional ice barrels are often shipped fully assembled to the point of use from a distant location. This results in wasted resources from shipping air in the interior cavity of the barrel. For example, often times, the cost of shipping the fully assembled conventional barrel is greater than the cost of the barrel itself. In addition, conventional ice barrels include injection molded interior walls which add to the weight of the barrel as compared to the portable barrel with expandable bladder disclosed herein. The reduced weight of the portable ice barrel disclosed herein provides efficiencies, for example, in shipping costs and ease of use. Users of conventional barrels often turn the barrel over to empty water from the interior cavity, which can lead to injury due to the weight of the barrel. The reduced weight of the portable barrel of the instant disclosure can, for example, reduce instances of injury from turning the barrel over. 
     The examples discussed herein proves for a lower cost unit, which can be easy shipped, assembled and disassembled at its final location. This may help companies who purchase coolers a tremendous amount of freight cost which, depending the shipping destination could actually exceed the cost of the entire unit itself. Printing outfits around the country in major metropolitan areas can print large, wrap around graphics for the particular region. For example, a printer in Los Angeles would print graphic wraps for the Dodgers, Angels, and Kings in addition to any other regionalized need. The printer would then assemble the coolers with those wraps and ship them out locally at a lower cost. 
     The present disclosure and the accompanying drawings make reference to a variety of examples. The purpose served by the disclosure, however, is to provide examples of the various features and concepts related to the portable ice barrel of the instant disclosure, not to limit the scope of the disclosure to the examples. One skilled in the relevant art will recognize that numerous variations and modifications may be made to the examples described above without departing from the scope of the subject matter disclosed herein.
