Description

FIELD

The present invention relates to a portable ice chest, in particular, a portable ice chest that can provide potable water.

BACKGROUND

Ice chests and portable ice chests are known and widely used. For example, see www.coleman.com. A user of conventional ice chests generally will encounter various drawbacks to these devices. The first is that where beverages or food are stored in an ice chest, and the ice ultimately melts into water, a user retrieving beverage or food stored in the ice chest will be forced to submerge their hand in the cold water, which may not be desirable. Another drawback of a conventional ice chest is that the water in the ice chest that results from the melting ice is not drinkable, due to contamination from the items stored in the ice chest. Such water is generally disposed of without further use. The presently described invention aims to provide a solution to the above-stated problems.

SUMMARY

In one aspect, the present description relates to an ice chest. The ice chest includes a main body and a hinged lid. The main body is made up in part of a bottom, two opposing elongate sides, and two opposing sides. The hinged lid is capable of being positioned over the main body and sealing the ice chest. The main body also includes a first internal compartment, second internal compartment and third internal compartment. The first and second internal compartments are separated from one another by a barrier that is capable of thermal transfer, but prohibits liquid transfers. The third internal compartment is positioned directly below the first and second internal compartments and positioned above the bottom of the main body. The third internal compartment is also capable of retaining liquid. The main body of the ice chest further includes a porous barrier that is positioned between the first and third internal compartments. The porous barrier is capable of filtering liquid traveling between the first and third internal compartments. The main body of the ice chest also has a filtered spout that is positioned on one of the opposing end sides of the third internal compartment. The filtered spout is capable of providing a second filtering mechanism and release mechanism for liquid being retained in the third internal compartment.
In another aspect, the present description relates to an ice chest that includes a first compartment adapted to hold a quantity of ice. When ice melts, water exits the first compartment of the ice chest but remains contained within the ice chest.

According to a first aspect of the invention, a portable ice chest 100 is shown in FIG. 1. A side view of ice chest 100 is shown in FIG. 2. Ice chest 100 includes a main body 102, the main body comprising a bottom 104, two opposing elongate sides (the front and rear sides are not shown for simplicity), and two opposing end sides 106, 108. The walls of ice chest 100 can be constructed from conventional insulating materials with a rugged exterior commonly used in commercially available ice chests and coolers.
Ice chest 100 further includes a lid 110 capable of being hinged and positioned over the main body 102. When closed, lid 110 seals the ice chest 100. Lid 110 can have a hard or soft exterior surface. In addition, lid 110 can include a pullout dual cup holder (not shown).
The main body 102 further includes multiple internal compartments. For example, in the embodiment shown in FIG. 1, the main body 102 includes three separate compartments. A first compartment comprises internal compartment 120. In one aspect, internal compartment 120 is configured to contain ice and/or bottled beverages. Main body 102 also includes a second internal compartment 130 positioned adjacent to internal compartment 120. In one aspect, second internal compartment 130 is configured to contain food, ice, ice packs, and/or bottled beverages. In this aspect of the invention, the second internal compartment 130 is separated by the first internal compartment 120 by a barrier 135 that is capable of thermal transfer, but that prohibits liquid transfer between the compartments 120, 130. As such, barrier 135 is configured to prevent food spillage or liquid flow between compartment 130 and compartment 120, thus reducing the likelihood of potential contamination of ice stored in compartment 120.
In one aspect, internal compartment 130 can have a smaller size/volume than compartment 120. In another aspect, internal compartment 130 can have a larger size/volume than compartment 120. In yet another aspect, internal compartment 130 can have the same size/volume as compartment 120.
In another aspect, compartment 130 can be a removable compartment. For example, a handle 132 can be provided to allow a user to remove compartment 130 when the ice chest is opened. In this aspect, main body 102 can include mechanism, such as slots, guides, or tracks, that slidingly receive removable compartment 130 and allow for the straightforward insertion or removal of the removable compartment 130.
The main body 102 further includes a third internal compartment 140 positioned directly below the first and second internal compartments 120, 130 and positioned above the bottom 104 of the main body 102. According to an aspect of the invention, the third internal compartment 140 is capable of retaining liquid. In this respect, third internal compartment 140 can be referred to as a reservoir 140.
In one example, a porous barrier 145 is positioned between the first and third internal compartments 120, 140. The porous barrier 145 can also be configured to filter liquid flowing between the first and third internal compartments 120, 140. In one aspect, the porous barrier 145 can be constructed as a single piece porous membrane. In another aspect, such as shown in FIG. 1, the porous barrier 145 can be constructed as a two part structure that includes a porous shelf 146 that allows liquid to pass through (and, in some instances, capture macro particles) and a filter 148 that filters the liquid entering compartment 140. In this aspect, filter layer 148 can be positioned within compartment 120 on internal ledge features 147. Simple fastening mechanisms (not shown) can be used to hold filter 148 and/or shelf 146 in place. As such, the lower compartment 140 can capture filtered water resulting from melted ice placed in the first compartment 120. In one aspect the porous shelf can be removable so that the filter 148 can be replaced on a regular basis. Alternatively, filter 148 can be cleaned using a hose or pressurized water spray.
In addition, ice chest 100 can further include a filter-spout combination, referred to herein as a filtered spout 155, positioned on one of the opposing end sides of the reservoir 140 (in FIG. 1, side 108). The filtered spout 155 can provide a second filtering mechanism (in addition to the filtering performed by the filter portion of porous barrier 145 in some aspects). In one aspect, the additional filtering can be provided by a cartridge-type filter 153, disposed at or near and in fluid communication with spout 155. The filter 153 can comprise a replaceable filter. In one aspect, the replaceable filter comprises a conventional water filter, such as those available from Brita (www.brita.com). In addition, filtered spout 155 also provides a release mechanism for liquid being retained in reservoir 140. Thus, this filtering arrangement can be capable of providing a source of potable water.
In another aspect of the invention, ice chest 100 can further include a visual indicator 157 that communicates a condition of the secondary filter. For example, if the condition of the secondary filter is good, the visual indicator 157 can provide a green light indication. If the condition of the secondary filter is not good (e.g., the secondary filter needs to be replaced), then the visual indicator can provide a red light. Other colors or visual indication symbols may also be utilized.
In another aspect of the invention, as shown in FIG. 2, the ice chest can further include a collapsible handle 172 that can be positioned on an external portion of one side of the ice chest, The collapsible handle is configured to extend to a desired height upon actuation of a handle release mechanism. In addition, one or more side handles 177 can also be provided.
In another aspect of the invention, the ice chest 100 further includes an additional drain spout 159 positioned on an end side (e.g., side 106) opposite the end side (e.g., side 108) on which the filtered spout 155 is positioned. The additional drain spout 159 can include an integral or separate end cap (not shown).
Additionally, ice chest 100 can further include at least two wheels (wheel 175 is shown in FIG. 2) positioned beneath the bottom of the main body proximate one of the opposing ends to provide additional ease of transportability. In one aspect, the wheels are configured to pivot and/or are configured to be collapsible.
With the configuration described above, ice chest 100 provides a first compartment 120 adapted to hold a quantity of ice, wherein as ice melts, water exits the first compartment 120 but remains contained within the ice chest in reservoir 140. Thus, if beverages are cooled in compartment 120, even as the ice melts, the beverages are not sitting in a pool of water, thus reducing the likelihood a user would have to submerge his or her hand into an ice cold pool. In addition, ice chest 100 provides a macro filter (e.g., barrier 145) so that the water contained in the reservoir 140 has undergone some filtering. The inclusion of a filtered spout 155 thus provides a source of potable water that can be consumed by the user, without having to waste the water.
Although specific embodiments have been illustrated and described herein, it will be appreciated by those of ordinary skill in the art that a variety of alternate and/or equivalent implementations can be substituted for the specific embodiments shown and described without departing from the scope of the present disclosure. This application is intended to cover any adaptations or variations of the specific embodiments discussed herein. Therefore, it is intended that this disclosure be limited only by the claims and the equivalents thereof.
