Abstract

Disclosed is a thermal insulating device comprising: (a) a container or compartment for holding food and/or beverage in a cooled condition, said container comprising thermoformed liner having an average thickness of not greater than about 10 mm, said liner being formed at least in part from material selected from the group consisting of glass-clear polystyrene (GPPS), impact-modified polystyrene (HIPS), styrene-butadiene block copolymers, ASA, SAN, ABS, polyolefins, acrylates and methacrylates, polycarbonates (PCs), polyvinyl chloride (PVC), polyethylene terephthalate (PET) and mixtures, combinations, laminates and layers of these; and (b) thermal insulation adjacent said liner and comprising a polymeric material having closed cells therein wherein said cells are formed from and/or contain a blowing agent comprising at least about 50% by weight of transHFCO-1233zd.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A thermal insulating device for containing item(s) or fluid(s) at a temperature below ambient temperature comprising: (a) a container or compartment for holding food and/or beverage in a cooled condition, said container comprising a food grade high impact polystyrene (HIPS) thermoformed liner having an average thickness of not greater than about 10 mm; and (b) thermal insulation adjacent said liner and comprising a polymeric material having closed cells therein wherein said cells are formed from and/or contain a blowing agent comprising at least about 50% by weight of transHFCO-1233zd. 
     
     
         2 . The thermal insulating device of  claim 1  wherein said liner has an average thickness of not greater than about 5 mm. 
     
     
         3 . The thermal insulating device of  claim 1  wherein said liner has an average thickness of not greater than about 2 mm. 
     
     
         4 . The thermal insulating device of  claim 1  wherein said liner has an average thickness of not greater than about 1 mm. 
     
     
         5 . A refrigerator comprising the thermal insulating device of  claim 1 . 
     
     
         6 . A refrigerator comprising the thermal insulating device of  claim 3 . 
     
     
         7 . A freezer comprising the thermal insulating device of  claim 1 . 
     
     
         8 . A freezer comprising the thermal insulating device of  claim 3 . 
     
     
         9 . A vending machine comprising the thermal insulating device of  claim 1 . 
     
     
         10 . A vending machine comprising the thermal insulating device of  claim 3 . 
     
     
         11 . A reach-in cooler comprising the thermal insulating device of  claim 1 . 
     
     
         12 . A reach-in cooler comprising the thermal insulating device of  claim 3 . 
     
     
         13 . A transport refrigeration unit comprising the thermal insulating device of  claim 1 . 
     
     
         14 . A transport refrigeration unit comprising the thermal insulating device of  claim 3 . 
     
     
         15 . A thermal insulating device for containing item(s) or fluid(s) at a temperature below ambient temperature comprising: (a) a container or compartment for holding food and/or beverage in a cooled condition, said container comprising thermoformed liner having an average thickness of not greater than about 10 mm, said liner being formed at least in part from material selected from the group consisting of glass-clear polystyrene (GPPS), impact-modified polystyrene (HIPS), styrene-butadiene block copolymers, ASA, SAN, ABS, polyolefins, acrylates and methacrylates, polycarbonates (PCs), polyvinyl chloride (PVC), polyethylene terephthalate (PET) and mixtures, combinations, laminates and layers of these; and (b) thermal insulation adjacent said liner and comprising a polymeric material having closed cells therein wherein said cells are formed from and/or contain a blowing agent comprising at least about 50% by weight of transHFCO-1233zd. 
     
     
         16 . The thermal insulating device of  claim 15  wherein said liner has an average thickness of not greater than about 5 mm. 
     
     
         17 . The thermal insulating device of  claim 15  wherein said liner has an average thickness of not greater than about 2 mm. 
     
     
         18 . The thermal insulating device of  claim 15  wherein said liner has an average thickness of not greater than about 1 mm. 
     
     
         19 . A refrigerator comprising the thermal insulating device of  claim 15 . 
     
     
         20 . A refrigerator comprising the thermal insulating device of  claim 17 . 
     
     
         21 . A freezer comprising the thermal insulating device of  claim 15 . 
     
     
         22 . A freezer comprising the thermal insulating device of  claim 17 . 
     
     
         23 . A vending machine comprising the thermal insulating device of  claim 15 . 
     
     
         24 . A vending machine comprising the thermal insulating device of  claim 17 . 
     
     
         25 . A reach-in cooler comprising the thermal insulating device of  claim 15 .
