Foldable insulated bag
View Patent ↗A soft sided insulated cooler bag has a base and side panels. The base includes a rigid or semi-rigid reinforcement or batten that serve to provide a relatively hard or stiff edge about which the bag can be panel folded over on itself. The upper edge of the bag has a length that is as great as half the periphery of the bottom panel. The bag can be collapsed to a flat position and then panel folded to a storage position. Retainers are provided to keep the bag in the storage position.
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
said forming panel including a stiffener member;
and wherein:
said foldable insulated bag has a base panel and a sidewall structure mounted about said base panel, said forming panel being said base panel;
said foldable insulated bag has a retainer operable to secure said foldable insulated bag in said folded storage position;
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 first edge connected to said first sidewall panel, and a second edge connected to said second sidewall panel;
said base panel has an outer face, and an inward face; in said flattened position said first edge of said base panel lies nearer than said second edge of said base panel to said second edge of said first sidewall panel;
said outer face of said base panel has a first member of said retainer mounted thereto adjacent to said second edge thereof;
said first sidewall panel has a second member of said retainer mounted adjacent to said second edge thereof; and
said base panel is movable to bring said first portion of said retainer into mating engagement with said second portion of said retainer.
2. The foldable insulated bag of claim 1 wherein said first and second members of said retainer are mating hook-and-eye fabric strip portions.
