A portable cooler has at least three separate storage compartments that comprise at least one ice-cold storage compartment; at least one dry moderately cold storage compartment; and at least one dry non-cold storage compartment. A temperature gradient construction enables the user to proficiently store food and non-food items of varying water sensitivities and temperature needs. Typically, a wet cooling medium is added to the ice-cold storage compartment. Discrete thermal conduction pathways extend from the ice-cold storage compartment into the moderately cold storage compartment, cooling the moderately cold storage compartment. The less cold compartment and the non-cold compartment are completely dry of water. Each of the compartments has its own lid enabling selective entry and thereby preventing temperature fluctuations and moister transfer when another compartment is accessed. The portable cooler has a plurality of foldable wheels on the base thereof to facilitate portability.

1. An insulated portable cooler, comprising:a. bottom, front, rear, left-side and right-side insulated exterior walls defining a container;b. insulated partition means for separating the interior of said container into at least two separate compartments;c. dividing wall means for separating the interior of said container into at least three separate compartments;d. at least one of said separate compartments functioning as an ice-cold storage compartment;e. at least one of said separate compartments functioning as a dry moderately-cold storage compartment;f. at least one of said separate compartments functioning as a dry non-cold storage compartment;g. thermal conduction pathways located on the bottom of said container extending from the ice-cold storage compartment into the dry moderately-cold storage compartment and adjacent to the dividing wall; andh. insulated individual lid means associated with each of the three separate compartments, said insulated lid means comprising a plurality of lids hinged to the rear exterior wall of the container and being operative to individually seal each compartment and allow selective entry therein;wherein the container has a multi-compartment gradient cooling construction that allows perishable and non-perishable food and non-food items to be stored at ice-cold, dry moderately cold, or dry non-cold temperatures. 2. An insulated portable cooler as recited by claim 1, wherein the ice-cold storage compartment is cooled by an added cooling medium, said cooling medium being selected from the group consisting of block ice, cubed ice, crushed ice, frozen cool packs, and mixtures of ice and salt.3. An insulated portable cooler as recited by claim 1, wherein the ice-cold storage compartment is used for storage of non-water sensitive food items that require ice-cold temperatures and are fully immersed in the cooling medium.4. An insulated portable cooler as recited by claim 1, wherein the ice-cold storage compartment has a drainage valve located near the bottom of the compartment to remove excess water therefrom.5. An insulated portable cooler as recited by claim 1, wherein the thermal conduction pathway comprises a heat conducting metal comprised of copper, aluminum, iron, steel, or tin.6. An insulated portable cooler as recited by claim 5, wherein said heat conducting metal comprises a bar and multiple fingers extending from the bottom of the ice-cold storage compartment and through the dividing wall of the moderately-cold storage compartment, and wherein the total cross sectional area of the said multiple fingers determines the amount of cooling transferred to the moderately-cold storage compartment. 7. An insulated portable cooler as recited by claim 5, wherein said heat conducting metal is covered by an insulating sheath, and said insulating sheath extends over the heat conducting metal.8. An insulated portable cooler as recited by claim 1, wherein the thermal conduction pathway comprises a closed loop coil containing a liquid medium, wherein the coil extends from the bottom of said ice-cold storage compartment and into the dry moderately-cold storage compartment, said coil further extending up into the exterior insulated walls and the dividing wall of the dry moderately-cold storage compartment, wherein the dividing wall has a conductive inner-casing wall surface in the moderately cold storage compartment, and said cooling action being produced by thermal conduction through the coil material and convection currents within the closed loop coil.9. An insulated portable cooler as recited by claim 8, wherein said closed loop coil contains a liquid having a freezing point greater than the temperature of the central storage compartment and may be comprised of salt water, ethylene glycol-water mixtures, or alcohol-water mixtures.10. An insulated portable cooler as recited by claim 8, wherein the closed loop coil is attached to a valve, the valve being interposed to control the convection flow current and the degree of cooling provided to the moderately-cold storage compartment. 11. An insulated portable cooler as recited by claim 1, wherein the dry non-cold storage compartment is completely insulated and dry, and is used to store non-food items and food items that are moisture sensitive and/or do not require cool temperatures.12. An insulated portable cooler as recited by claim 1, wherein the thermal conduction pathway comprises an interior cavity extending along at least two walls comprising the moderately cold storage compartment, the interior cavity extends along the inner perimeter of at least one of the dry moderately-cold storage compartment's insulated exterior walls, a thermally conductive inner-casing wall extends along the inner-most perimeters of said interior cavity so that the interior cavity is located between the inner-casing wall and the insulated exterior wall(s), and said interior cavity and thermally conductive inner-casing wall extend along the dividing wall of the dry moderately-cold storage compartment.13. An insulated portable cooler as recited by claim 12, wherein said interior cavity has at least one entry lid so that cooling medium can be added thereto, said cooling medium being selected from the group consisting of block ice, cubed ice, crushed ice, frozen cool packs, and mixtures of ice and salt.14. An insulated portable cooler as recited by claim 12, wherein the interior cavity has a drainage valve.15. An insulated portable cooler as recited by claim 1, wherein the side insulated exterior walls include foldable handles for lifting and carrying said cooler. 16. An insulated portable cooler as recited by claim 1, wherein there is a plurality of foldable wheels mounted on the bottom of the container to facilitate transportation thereof.17. An insulated portable cooler as recited by claim 16, wherein said plurality of foldable wheels consists of five wheels that are attached to the main body of the container through axles, said wheels being adapted by spring folding means to fold inwards for easy storage.18. An insulated portable cooler as recited by claim 1, further comprising a foldable handle attached to one of the side insulated exterior walls for pulling means.19. An insulated portable cooler as recited by claim 1, wherein the insulated exterior walls, the insulated partition, and the dividing wall are comprised of an insulated flexible polymeric material to allow said cooler to collapse for convenient storage when not in use.20. An insulated portable cooler as recited by claim 1, wherein the outermost exterior of the cooler is a wicker outer casing with insulated exterior walls.21. An insulated portable cooler as recited by claim 1, wherein the thermal conduction pathway comprises both an interior cavity extending along at least two walls comprising the moderately cold storage compartment and a heat conducting metal bar with multiple fingers extending into the moderately cold storage compartment.22. An insulated portable cooler as recited by claim 1, wherein the thermal conduction pathway comprises both an interior cavity extending along at least two walls comprising the moderately cold storage compartment and a closed loop coil containing a liquid medium, the coil extends from the bottom of said ice-cold storage compartment and into the dry moderately-cold storage compartment, said coil further extends up into the exterior insulated walls and the dividing wall of the dry moderately-cold storage compartment, and the dividing wall has a conductive inner-casing wall surface in the moderately cold storage compartment.
