Abstract
A portable soft sided insulated container has an impermeable liner that provides a liquid holding barrier. The liner is folded from a single monolithic plastic sheet to reduce or eliminate the need for heat welded seams. The liner seats within the container and has a releasable attachment around its lip for mating with the rim of the container. The container has an insulated lid so that the entire assembly may be closed. The liner can be removed for cleaning, or replacement if punctured. When not in use the entire assembly can be folded into a collapsed position for storage. The container has two storage chambers that share a common insulated dividing wall.
Claims29
A soft sided insulated container comprising:
- an insulated enclosure structure having an upper portion and a lower portion;
- said lower portion having a bottom wall, a front wall, a rear wall, a first end wall and a second end wall co-operatively connected to define a first chamber;
- said upper portion having a first end wall, a second end wall and a spanning wall co-operatively connected to define a second chamber;
- a permanently attached partition mounted between said upper portion and said lower portion, said partition member having a periphery;
- said lower portion having an upper margin matable with said periphery of said partition;
- said upper portion having a lower margin matable with said periphery of said partition;
- said enclosure structure having a first opening defined therein by which to obtain access to said first chamber, and a first closure member operable to inhibit access to said first chamber;
- said enclosure structure having a second opening defined therein by which to obtain access to said second chamber, and a second closure member operable to inhibit access to said second chamber;
- said end walls of said upper portion each having an upper edge having a downwardly concave profile;
- said spanning wall conforming to said downwardly concave profile;
- and
- said partition fully closing off said first and second chambers from each other whereby said partition forms a bottom panel of said upper portion and a top panel of said lower portion.

A soft-sided insulated container comprising:
- an upper portion and a lower portion;
- said upper portion having,
- a rectangular bottom wall having a pair of short sides and a pair of long sides;
- a pair of first and second opposed end walls each standing upwardly of one of said short sides of said bottom wall;
- each of said end walls having an upper edge, said upper edges having a downwardly widening profile;
- an intermediate wall having a front wall margin, a rear wall margin, and a top wall portion intermediate said front and rear wall margins;

- said front wall margin and said rear wall margin being opposed and extending upwardly of respective first and second ones of said long sides of said bottom wall, between said end walls;
- said top wall portion conforming to said profile of said upper edges of said end walls;
- said top wall portion extending between said rear wall margin and said front wall margin;
- said bottom wall, intermediate wall, and said first and second end walls defining a first chamber;
- said insulated container having a first opening defined therein by which to obtain access to said first chamber, and a first closure member operable to inhibit access to said first chamber;
- said lower portion has insulated wall members co-operating with said bottom wall of said upper portion to define a second insulated chamber;
- and
- said insulated container having a second opening defined therein by which to obtain access to said second chamber, and a second closure member operable to inhibit access to said second chamber.
