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.
Claims44
A soft-sided insulated container assembly comprising:
- a lower portion having
- a rectangular base having a pair of long edges and a pair of short edges;
- soft-sided insulated front and rear walls attached to, and extending upwardly from, said long edges,
- soft-sided insulated end walls attached to, and extending upwardly from, said short sides,
- said front and rear walls and said end walls co-operating with said base to define said lower portion;
- an upper portion mounted above said lower portion, said upper portion having
- a pair of end walls, each of said end walls having a lower margin mounted adjacent to one of said end walls of said lower portion, and an upper edge, said upper edge having a downwardly concave arcuate profile, and
- a soft-sided insulated spanning wall extending between said end walls of said upper portion, said spanning wall conforming to said concave arcuate profile.
A soft sided insulated container assembly comprising:
- a first insulated container portion, a second insulated container portion and a common wall shared between said first and second container portions;
- said first container portion having a first insulated wall structure and a first chamber defined therewithin;
- said second container portion having a second insulated wall structure and a second chamber defined therewithin;
- said first insulated wall structure having a bottom wall, a front wall, a rear wall and first and second end walls;
- said second insulated wall structure having
- a pair of end walls, each of said end walls having an upper edge having a downwardly concave profile, and
- a spanning wall extending between said end walls and conforming to said downwardly concave profile;
- said common wall being a partition member segregating said first and second chambers from each other, said partition member having a first closure member mounted thereto operable to control access to said first chamber, and having a second closure member mounted thereto operable to control access to said second chamber;
- and
- said common wall having an edge and a hinge mounted along said edge, said hinge permitting said first container portion to move relative to said second container portion.
A soft-sided container assembly comprising:
- a first insulated wall structure having a primary chamber defined therewithin;
- said first insulated wall structure having a lower portion having a bottom wall, a front wall, a rear wall and first and second end walls;
- said first insulated wall structure having an upper portion mounted to said lower portion, said upper portion having a pair of end walls, each of said end walls having a downwardly concave profile, and a spanning wall extending between said end walls and conforming to said downwardly concave profile;
- a second insulated wall structure having a secondary chamber defined therewithin;
- said second insulated structure being removably locatable within said first insulated wall structure.
A soft-sided container assembly comprising:
- a first insulated wall structure having a primary chamber defined therewithin;
- a second insulated wall structure having a secondary chamber defined therewithin;
- said second insulated structure being removably locatable within said first insulated wall structure;
- said first insulated wall structure having a receptacle mounted therewithin for containing a thermal energy storage element, said receptacle being vented to permit air exchange between said first chamber and said receptacle;
- said first insulated wall structure having a first portion, a second portion, and a closure member operable to permit said first portion to be displaced relative to said second portion, thereby giving access to a first volume defined within said first portion, and a second volume defined within said second portion, and said first insulated wall structure has a divider mounted between said first and second portions.
A soft-sided insulated container assembly, comprising:
- a first soft-sided insulated wall structure having a rectangular base, and rectangular sides extending upwardly from said rectangular base, said first insulated wall structure having a first insulated chamber defined therewithin;
- a second soft-sided insulated wall structure having a pair of end walls, said end walls having upper margins defining a lid contour, and a longitudinal wall extending between said end walls and conforming to said lid contour, said second insulated wall structure defining a second insulated chamber therewithin,
- said second insulated wall structure being locatable above said first insulated wall structure;
- and
- an insulated divider mounted between said first and second insulated wall structures to segregate said first chamber from said second chamber.
A soft sided insulated container assembly, comprising:
- a first soft-sided insulated wall structure;
- a second soft-sided insulated wall structure having a pair of end walls, said end walls having upper margins defining a lid contour, and a longitudinal wall extending between said end walls and conforming to said lid contour;
- said second soft-sided insulated wall structure being locatable above said first soft-sided insulated wall structure, said first and second soft-sided insulated wall structures co-operating to define a first chamber therewithin;
- a first closure member mounted to said first and second soft-sided insulated wall structures, said first closure member being operable to permit displacement of said first soft-sided insulated wall structure relative to said second soft-sided insulated wall structure to give access to said first chamber;
- and
- a third soft-sided insulated wall structure defining a second chamber therewithin, said third soft-sided insulated wall structure having a second closure member operable to give access to said second chamber;
- said third soft-sided insulated wall structure being locatable within said first chamber;
- and
- said third soft-sided insulated wall structure being removable from within said first chamber.
