Abstract

A soft sided insulated container assembly has a first insulated container portion and a second insulated container portion. The second insulated container portion can be collapsed to a flat position, and secured in place. Either of the container portions may have a liner. The liner in the first container portion may be a substantially rigid liner. The assembly may have a lifting member. In one example the second portion may be hingedly mounted to the first portion, and the lifting member may be mounted such that when the assembly is lifted, the hinge is in an up-and-down orientation. In another embodiment, the lifting member may be eccentrically mounted, such that the assembly may possibly sit more comfortably against a carrier'"'"'s hip. The first container portion may have an auxiliary opening or door, and that door may be more easily opened than the main access of the first insulated container portion.

said second panel being hingedly mounted to said margin of said peripheral wall along one of said long sides thereof;

said second panel being movable between a closed position and an open position relative to said peripheral wall;

a first closure operable releasably to secure said second panel in said closed position;

said second container portion being a soft-sided;

said second soft-sided, container portion being mounted to said second panel of said first, soft-sided, insulated container portion;

said second soft-sided container portion being movable from a collapsed position to an expanded position, and said container assembly including members operable releasably to secure said second container portion in said collapsed position;

said second soft-sided, container portion having a predominantly rectangular footprint corresponding substantially to said predominantly rectangular plan form of said second panel of said first container portion, having respective first and second long sides, and respective first and second short sides; and

said second container portion having a second closure mounted along one of said first and second short sides thereof;

said soft-sided insulated container assembly defining a lunch container assembly adapted for use maintaining either of foods and beverages in a cooled or warmed condition.

2. The container assembly of claim 1 wherein:

said peripheral wall has a pair of first and second short sides, and a pair of first and second long sides, those short and long sides standing along the respective first and second short and long sides of said first panel, said first short side of said peripheral wall being closest adjacent to said second closure member; and

a lifting member is mounted to said peripheral wall whereby said first short side of said peripheral wall is positioned uppermost relative to said second short side of said peripheral wall when said container assembly is supported by said lifting member.

3. The container assembly of claim 2 wherein said lifting member is a handle mounted to said first short side of said peripheral wall of said first, soft-sided, insulated container portion.

4. The container assembly of claim 2 further comprising a second lifting member that includes a shoulder strap.

5. The container assembly of claim 1 wherein said second container portion includes a main panel and a peripheral wall, the main panel has a peripheral margin having a pair of long portions and a short portion adjoining each other in a U-shape, said short portion being distant from said second closure member, and said peripheral wall being collapsible to permit said main panel of said second container portion to move to a position closer to said second panel when said second container portion is in said collapsed position than when said second container portion is in said expanded position.

6. The container assembly of claim 5 wherein said second closure member has a first securement member operable to retain said second closure member in a closed position relative to said second container portion, and a second securement member operable to retain said closure member against said main panel when said second container portion is in said collapsed position.

7. The container assembly of claim 1 wherein an auxiliary lodgement is mounted to one of said long sides of said peripheral wall of said first, soft-sided, insulated container portion opposite to that long portion of said peripheral sidewall to which said second panel is hingedly mounted.

8. The container assembly of claim 7 wherein said lodgement is uninsulated, has a base which may be collapsed against said peripheral wall when not in use, and which has an open end closest to said first short side of said peripheral wall.

9. The container assembly of claim 1 wherein at least one of said first and second container portions has a liner.

10. The container assembly of claim 9 wherein said liner is more rigid than said insulated peripheral wall.

11. The container assembly of claim 1 wherein said insulated container wall of said first insulated container portion includes an outer skin, an inner skin, and a flexible foam insulation layer captured between said inner and outer skins.

12. The container assembly of claim 1 wherein a removable washable liner is mounted within said first insulated container portion.

13. The container assembly of claim 1 wherein said container is in which said length lies in the range of 1 to 2 times said width, and said length is in the range of 2 to 5 times said depth.

14. A lunch box assembly comprising:

a soft-sided insulated container having a first portion and a second portion;

said first portion having the shape of a rectangular box having a length, a width and a depth;

said length and width being greater than said depth;

said length being greater than said width;
