The frame may include perimeter walls and interior walls interconnecting the perimeter walls, thereby forming a plurality of container sections having openings. At least one interior wall may be configured to facilitate heat transfer between neighboring container sections via heat conducting material. The system may include a plurality of access hatches covering at least some of the openings.

Description
- The present disclosure relates generally to thermally insulated container systems. In particular, multi-compartment thermally insulated container systems are described.
- Known thermally insulated container systems are not entirely satisfactory for the range of applications in which they are employed. For example, existing thermally insulated container systems, such as coolers, typically have only one compartment. Thus, opening the lid to the single compartment exposes the contents of the entire container to the ambient atmosphere, thereby diminishing the effectiveness of the container. Furthermore, such single compartment systems are not capable of maintaining several different temperatures simultaneously, as might be desired based on the items to be stored.
- In addition, conventional thermally insulated container systems may allow ice and melt-water to commingle with items which are preferably kept dry. Conventional thermally insulated container systems may also allow for undesired movement of items, for example after ice has melted these items may float.
- Thus, there exists a need for thermally insulated container systems that improve upon and advance the design of known thermally insulated container systems. Examples of new and useful thermally insulated container systems relevant to the needs existing in the field are discussed below.
- Multi-compartment insulated container systems and methods of using the same are described below. In one embodiment, a container system includes a frame. The frame may include perimeter walls and interior walls interconnecting the perimeter walls, thereby forming a plurality of container sections having openings. At least one interior wall may be configured to facilitate heat transfer between neighboring container sections via heat conducting material. The system may include a plurality of access hatches covering at least some of the openings. The plurality of access hatches may be configured to retard heat transfer between the exterior of the frame and the interior via heat insulating material. In some embodiments, the frame may be configured to be housed within an exterior container. The exterior container may be thermally insulated.
- In one embodiment a method of using a multi compartment insulated container system includes the steps of placing a first item into an opening of a first container section of a plurality of container sections, the plurality of container sections being disposed within a heat insulated exterior container; and closing a first access hatch of the first container section, thereby covering the opening and insulating the first item from an ambient environment via heat insulating material disposed in the access hatch. The plurality of container sections may be formed by a frame comprising perimeter walls and interior walls interconnecting the perimeter walls. At least one interior wall is configured to facilitate heat transfer between a neighboring container section via heat conducting material disposed within the at least one interior wall. The first container section may include an opening.

The detailed description and figures provide merely examples of the various inventions described herein. Those skilled in the art will understand that the disclosed examples may be varied, modified, and altered without departing from the scope of the inventions described herein. Many variations are contemplated for different applications and design considerations; however, for the sake of brevity, each and every contemplated variation is not individually described in the following detailed description.
- Throughout the following detailed description, examples of various multi-compartment insulated container systems are provided. Related features in the examples may be identical, similar, or dissimilar in different examples. For the sake of brevity, related features will not be redundantly explained in each example. Instead, the use of related feature names will cue the reader that the feature with a related feature name may be similar to the related feature in an example explained previously. Features specific to a given example will be described in that particular example. The reader should understand that a given feature need not be the same or similar to the specific portrayal of a related feature in any given figure or example.
- The disclosed multi-compartment insulated container systems provide a plurality of separate container sections. Each separate section may have its own thermally insulated access hatch, and thus each section may be kept thermally isolated from the other sections as well as the ambient atmosphere. Thus a user may access each compartment independent of the other compartments, allowing the items in the unaccessed compartments to remain cooler (or hotter) for longer.
- Furthermore, in some embodiments, the walls that separate certain groups of adjacent compartments may be comprised of thermally conductive material. Thus, a heat source (such as a hotpack or an amount of hot water) or a heat sink (such as an amount of ice) may be placed in one compartment, and items to be heated or cooled, as desired, may be placed in an adjacent compartment. In this fashion, items may be kept separate from heat sources and/or heat sinks, thereby keeping the items dry. Furthermore, container sections containing items such as food, beverage or medicine may be opened without exposing the heat source and/or sink in an adjacent compartment section to the ambient environment.
- In addition, by storing items in smaller containers and separately from heat sources and/or sinks, the multi-compartment insulated container system reduces the unwanted shifting of the items due to ice melt or transportation of the multi-compartment insulated container system.
- In some embodiments, the multi-compartment insulated container system may be used in conjunction with a conventional insulated container system, such as a cooler. For example, in some embodiments, the multi-compartment insulated container system may be configured to slide snugly into the interior chamber of a cooler, thereby allowing the lid of the cooler to be closed with the multi-compartment insulated container system inside. In other embodiments, the multi-compartment insulated container system may be used as a stand-alone system.
- With reference to
FIGS. 1-4 , a first example of a multi-compartment insulatedcontainer system 20, will now be described.Container system 20 comprises a frame having perimeter walls 31-34, interior walls 40-49. Interior walls 40-49 may interconnect perimeter walls 31-34, thereby forming a plurality of container sections 51-58 having openings. The openings may be covered by one or more access hatches, such as exemplary access hatches 71-72. - As can be seen in
FIG. 1 , perimeter walls 31-34 may form an outer perimeter surrounding container sections 51-58. In some embodiments, the perimeter walls may be configured to retard heat transfer between the exterior of the frame and the interior of the frame. Thus, perimeter walls 31-34 may function to thermally insulate container sections 51-58 from the ambient atmosphere. In this regard, perimeter walls 31-34 may comprise heat insulating material. In some embodiments, perimeter walls 31-34 may be at least partially hollow, thus trapping air to thermally insulate container sections 51-58. - In a preferred embodiment, heat insulating materials are those materials having a thermal conductivity of not greater than 0.7 W/mK (watts per meter-Kelvin). Examples of insulating materials include polyethylene materials such as high density polyethylene (HDPE) and/or low density polyethylene (LDPE), polypropylene, polyurethane foam, polystyrene, polyamides, and polytetrafluoroethylene (PTFE), some types of wood and/or composites, among many others.
- As shown in
FIG. 1 , interior walls 40-49 interconnect the perimeter walls to form container sections 51-58. While the system ofFIG. 1 includes a 4×2 grid of container sections, as the reader can appreciate, the perimeter walls and interior walls may be arranged in a wide array of configurations to form a multitude of container section configurations. - At least one interior wall may be configured to facilitate heat transfer between neighboring container sections via heat conducting material. For example,
