Foldable insulated bag with trailing member
A Foldable Insulated Container may be made of a three piece assembly of a base, a front wall and a rear wall. The base may include a reinforcement such as may tend to urge the base to retain a substantially planar orientation, and which may aid in folding the insulated bag. The insulated bag may include a trailing member. The trailing member may be attached to the base. The trailing member may include wheels. The trailing member, or apparatus, may include a retractable wheeled undercarriage.
1 . A foldable insulated bag comprising:
an insulated wall structure, defining an insulated space therewithin;
said wall structure having a closure member operable to govern access to said insulated space; and
said wall structure including a forming panel;
said wall structure, when empty, being movable to a first. flattened position;
said wall structure being foldable about at least a portion of said forming panel to a folded storage position;
said wall structure being securable in said folded storage position; and
an undercarriage mounted to said insulated wall structure to facilitate towing thereof.
2 . The foldable insulated bag of claim 1 wherein said undercarriage is retractable.
3 . The foldable insulated bag of claim 1 wherein said bag includes a retainer, said retainer being operable to secure said bag in said folded storage position.
4 . The foldable insulated bag of claim 1 wherein said bag has a bottom region and a top region, and a suspension member is mounted distantly from said bottom region.
5 . The foldable insulated bag of claim 1 wherein said forming panel includes a stiffener member.
6 . The foldable insulated bag of claim 1 wherein said forming panel has a flexural rigidity greater than any other portion of said bag.
7 . The foldable insulated bag of claim 1 wherein said forming panel has an insulating layer and a stiffening layer.
8 . The foldable insulated bag of claim 1 wherein said bag has a base panel and a sidewall structure mounted about said base panel, said forming panel being said base panel.
9 . The foldable insulated bag of claim 8 wherein said undercarriage is mounted to said base panel.
10 . The foldable insulated bag of claim 1 wherein said undercarriage includes wheels.
11 . The foldable insulated bag of claim 1 wherein said undercarriage is movable between an extended position and a retracted position, and includes a fitting operable to discourage accidental retraction of said undercarriage.
12 . The foldable insulated bag of claim 1 wherein said undercarriage includes a retracted position retainer.
13 . The foldable insulated bag of claim 8 wherein said sidewall structure includes first and second opposed sidewall panels, each sidewall panel having a first edge adjoining said base panel and a second edge distant therefrom. said closure member being mounted to said distant edges.
14 . The foldable insulated bag of claim 13 wherein said first and second members of said retainer are mating hook-and-eye fabric strip portions.
15 . The foldable insulated bag of claim 10 wherein:
said sidewall structure includes first and second opposed sidewall panels, each said sidewall panel having a first edge adjoining said base panel and a second edge distant therefrom;
said base panel has a periphery, said periphery including a first edge adjoining said first edge of said first sidewall panel, and a second edge adjoining said first edge of said second sidewall panel;
said periphery including two opposed remainder portions between said first and second sides, said portions having lengths 2a 1 and 2a 2 respectively;
said first edge of said first sidewall panel having a length. L:
said first edge of said base panel having a length ‘b’; and
said length L being at least as great as b+(a 1 +a 2 ).
16 . The foldable insulated bag of claim 15 wherein said first edge of said first sidewall panel is centered relative to said first edge of said base panel.
17 . The foldable insulated bag of claim 10 wherein:
said sidewall structure includes first and second opposed sidewall panels, each said sidewall panel having a first edge adjoining said base panel and a second edge distant therefrom;
said base panel is rectangular, having two opposed sides of length ‘b’ and two opposed sides of length ‘a’:
said first edge of said first sidewall panel has a length, L; and
said length L being at least as great as b+2a.
18 . The foldable insulated bag of claim 17 wherein said first edge of said first sidewall panel is centered relative to said first edge of said base panel.
