Problems solved by technology

Conventional cooler bags are not properly insulated to maintain the temperature inside the bag of below 40° to preserve food perishables stored in the cooler bag and are prone to leak due to the material composition of the bag and the method of construction in insulating the bag.
In addition, conventional cooler bags tend to leak and do

Embodiment Construction

[0013]The preferred embodiment of the cooler bag of the present invention is shown in FIGS. 1, 2A, 2B, 3 and 4 inclusive. The cooler bag 10 comprises two compartments 12 and 14, as shown in FIGS. 2A and 2B with each compartment 12 and 14 enclosing a layer of insulation preferably in the form of a solid sheet of closed cell foam insulation 15 and 17 with each sheet of insulation 15 and 17 being essentially identical in composition and selected from the group consisting of fiberglass, polyurethane or expanded polystyrene and having a minimum thickness of about one inch in dimension. Each insulation sheet 15 and 17 should consist of a multiplicity of closed cells of relatively high density.

[0014]The bag 10 and each of its two compartments 12 and 14 is formed from a composition of flexible plastic, preferably fiber interlaced polyvinyl chloride (PVC). The compartments 12 and 14 of the bag 10 are formed with each compartment surrounding a sheet of insulation 15 and 17, preferably by heat...

Abstract

An insulated cooler bag and method comprising at least two separate and independent sealed compartments with each compartment composed of a flexible resistant plastic with the two compartments joined to form sealed seams along the bottom end of the bag and along opposite sides of the bag further comprising a zipper connected to each compartment at an end corresponding to the top end of the bag for opening and closing the bag based upon the direction of movement of the zipper relative to the side seams such that when the zipper is opened the sealed compartments expose a space therebetween corresponding to the interior of the bag into which items may be inserted for storage and when the zipper is closed the bag the sealed compartments overlap to form a double layer of thick foam cell insulation surrounding the interior of the bag and further comprising a drain plug connected to the interior of the bag.

Description

FIELD OF THE INVENTION[0001]The present invention is directed to an insulated cooler bag and method for insulating a cooler bag so that its interior is able to retain an inside temperature of below 40° for long periods of time to preserve perishables stored in the cooler bag.BACKGROUND OF THE INVENTION[0002]Conventional cooler bags are not properly insulated to maintain the temperature inside the bag of below 40° to preserve food perishables stored in the cooler bag and are prone to leak due to the material composition of the bag and the method of construction in insulating the bag. In addition, conventional cooler bags tend to leak and do not have drain valves for draining or cleaning the bag. Bag leakage causes the interior temperature of the bag to rise which increases the tendency for further leakage and decreases the period of time for preserving the food perishables.[0003]Insulated cooler bags are growing increasingly popular in the marketplace particularly for preserving fres...
