Soft-sided insulated container with thermal storage member
View Patent ↗A portable, foldable, soft-sided insulated container has an a lid mounted carrier, or seat, for a substantially rigid container of a thermal storage medium, such as water. The container assembly may be free of any rigid tub, and may thus retain the ability to fold. The carrier is a substantially rigid plate or panel, or array, that mounts to an otherwise soft panel. The panel, or portion of a panel, to which the rigid carrier mounts is a panel that may tend to stay substantially flat (or curved) when the container assembly is folded. The mounting is such that the substantially rigid thermal storage medium container can slide in and out of the seat. When not in use the entire assembly can be folded into a collapsed position for storage.
1. A collapsible, soft-sided insulated container assembly comprising:
a soft sided insulated wall structure including a plurality of sides mutually connected along vertices, said wall structure having folds along which said wall structure may be moved between a first position, that first position being a folded position, and a second position, that second position being an expanded position in which said wall structure defines an insulated chamber of said container into which an object may be placed, said wall structure including a closure member movable between open and closed conditions to govern access to said insulated chamber;
said wall structure including a first fabric wall portion having a width, a breadth, and a thickness, said thickness being less than half of either said width and said breadth;
said first fabric wall portion including an inner skin, an outer skin, and a layer of insulation located between said inner skin and said outer skin;
a substantially rigid thermal storage member;
a substantially rigid thermal storage member seat;
said thermal storage member seat including a land conforming to said first fabric wall portion of said wall structure and being mounted adjacent said inner skin thereof such that said thermal storage member seat is, in use, oriented inwardly relative to said insulated chamber;
said thermal storage member seat including a guide, said guide being mounted proud of said inner skin of said fabric wall portion; and
said thermal storage member being slidingly engageable with said guide in a direction predominantly cross-wise to said first fabric wall portion.
2. The collapsible, soft-sided insulated container assembly of claim 1 wherein said first fabric wall portion is oriented such that when said closure member is in said open condition said thermal storage member is exposed and slidably disengageable from said guide.
3. The collapsible, soft-sided insulated container of claim 1 wherein said first fabric wall portion defines a lid panel of said container assembly.
4. The collapsible, soft-sided container assembly of claim 1 wherein said thermal storage member seat includes a pair of guide members defining a track, and said thermal storage member has mating fittings operable to engage and run along said track.
5. The collapsible, soft-sided container assembly of claim 1 wherein said first fabric wall portion remains substantially flat when said assembly is moved to said first position.
6. The collapsible, soft-sided container assembly of claim 1 wherein said first fabric wall portion is a sub-portion of a larger wall panel.
7. The collapsible soft-sided container assembly of claim 1 wherein:
said first fabric wall portion is substantially planar and defines a top wall of the assembly, said top wall being hingedly movable to define said closure member;
said seat being substantially planar;
said seat being mounted to, and being substantially parallel to, said top wall; and
said thermal storage member being movable substantially sideways relative to said top wall to engage and disengage said seat.
8. The collapsible soft-sided container assembly of claim 4 wherein:
said first fabric wall portion is substantially planar and defines a top wall of the assembly, said top wall being hingedly movable to define said closure member;
said seat being substantially planar;
said seat being mounted to, and being substantially parallel to, said top wall; and
said thermal storage member being movable substantially sideways relative to said top wall to engage and disengage said seat.
