ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to containers and, in particular, to systems and methods that utilize containers for storing items so that the temperature of the items may be maintained, raised and/or cooled as desired.
2. Description of the Related Art
Oftentimes, it is desirable to transport items, such as beverages, for example, in a portable container or cooler so that convenient access to the beverages is provided, such as while playing golf, attending sporting events, going to a beach, etc. Hereinbefore, such a container typically has been formed of either insulating material, for maintaining the temperature of previously chilled beverages, or a combination of insulating material and cooling material, such as blue ice, for instance, whereby the cooling material chills a beverage stored within the container and the insulating material tends to maintain the temperature of both the cooling material and the chilled beverages.
For example, U.S. Pat. No. 4,741,176, issued to Johnson, et al., discloses a beverage cooler, which includes a cylindrical freezer-pack insert to be placed into a cup, and a cover. In an embodiment of the Johnson device, the cylindrical freezer-pack insert includes removable sections to change its size, and removable plugs for putting coolant fluid into the removable sections. Since, however, the Johnson device is adapted for inserting within an individual cup, the device is limited for use in cooling one beverage at a time.
As another example, U.S. Pat. No. 4,295,345, issued to Atkinson, discloses a cooling container for canned beverages. The Atkinson device includes a reusable concave container for carrying and cooling canned beverages having a bottom section containing a plurality of cylindrical compartments, a top section containing corresponding compartments having a slow warming cooling gel in the upper end thereof, and a shoulder strap for carrying the container. While it is apparent that the Atkinson device addresses the problem of cooling multiple beverages simultaneously, it does not, however, provide for increased cooling efficiency of the beverages stored therein, as the cooling gel is stored only in the upper end of the container.
It also may be desirable to transport other items in a portable container. By way of example, various items, such as fluids, organs and/or other medical-related items, may require transport. Heretofore, these items typically have been transported within containers that are not specifically adapted for these items. This inadequacy also is prevalent in fields other than the medical industry. Therefore, there is a need for improved coolers which address these and/or other shortcomings of the prior art.
BRIEF SUMMARY OF THE INVENTION
Briefly stated, the present invention is directed to systems and methods that utilize containers for storing and/or transporting items. In this regard, one such method includes: providing an item; providing a container, the container having: an outer shell, a cap, a storage chamber, an insulating material and a re-freezable material, the outer shell defining an interior and having at least one opening for providing access to the interior, the outer shell being formed of a substantially rigid material, the cap being configured to engage the opening, the cap being formed of a substantially rigid material and movable between an open position and a closed position, in the closed position the cap engaging the at least one opening such that the cap and the outer shell encase the interior, the storage chamber being located within the interior and communicating with the at least one opening, the storage chamber being adapted to receive the item such that the storage chamber substantially conforms to the exterior of the item, the insulating material disposed within the interior between the storage chamber and the outer shell, the re-freezable material disposed within the interior between the storage chamber and the insulating material such that the re-freezable material at least partially surrounds the exterior of the item inserted within the storage chamber, the ref-freezable material comprising an acrylate-based superabsorbent; placing the item in the storage chamber of the container; and moving the cap to the closed position.
Another embodiment of a method includes: providing a container sized and shaped to receive an item, the container having: a storage chamber, an insulating material and a re-freezable material, the insulating material defining an interior and having at least one opening for providing access to the interior, the re-freezable material being disposed within the interior, the insulating material comprising soyoyl polyol, the re-freezable material comprising an acrylate-based superabsorbent.
Another embodiment of a method includes: providing a container, the container having: an outer shell, a lid, a storage chamber, an insulating material, and a temperature-maintaining material, the outer shell defining an interior and having at least one opening for providing access to the interior, the outer shell being formed of a substantially rigid material, a lid configured to engage the outer shell and being formed of a substantially rigid material, the lid defining a lid opening and having a cap, the cap movably engaging the lid, the cap being movable between an open position and a closed position, in the closed position the cap engaging the lid opening such that the lid and the outer shell encase the interior, in the open position the lid opening providing access to the interior, the storage chamber being located within the interior and communicating with the at least one opening, the storage chamber being adapted to receive the item, the insulating material being disposed within the interior between the storage chamber and the outer shell, the temperature-maintaining material being disposed within the interior between the storage chamber and the insulating material, the temperature-maintaining material comprising an acrylate-based superabsorbent.
An embodiment of a container includes: an outer shell defining an interior and having at least one opening for providing access to the interior, the outer shell being formed of a substantially rigid material; a lid configured to engage the outer shell and being movable between an open position and a closed position, in the closed position the lid engaging the outer shell such that the lid and the outer shell encase the interior, in the open position the lid providing access to the interior; a storage chamber formed within the interior and communicating with the opening, the storage chamber being adapted to receive at least one item; insulating material disposed within the interior between the storage chamber and the outer shell; an inner wall spaced from the outer shell and located between the outer shell and the storage chamber; and temperature-maintaining material disposed within the interior.
An embodiment of a container includes: an interior defined at least partially by insulating material, the insulating material comprising soyoyl polyol; and a temperature-maintaining material disposed within the interior, the temperature-maintaining material comprising an acrylate-based superabsorbent.
Other systems, methods, features, and advantages of the present invention will be or become apparent to one with skill in the art upon examination of the following drawings and detailed description. It is intended that all such additional systems, methods, features, and advantages be included within this description, be within the scope of the present invention, and be protected by the accompanying claims.
