Soft-sided insulated container with thermal storage member

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.
