Abstract

Disclosed are devices and liners for containing item(s) or fluid(s) at a temperature below ambient temperature comprising: (a) a container or compartment having an interior space and (b) thermal insulation comprising a polymeric material having closed cells therein wherein said cells are formed from and/or contain a blowing agent, said container comprising a liner comprising (i) a first layer comprising ABS and having a surface facing toward said interior space; and (ii) at least a second layer having a surface facing away from said interior space and toward said thermal insulating foam, wherein said second layer of said liner is at least one of (1) a layer formed from an amorphous or semi-crystalline polyamide resin having sufficient composition and thickness to substantially inhibit the migration of said blowing agent toward said interior space; (2) a layer formed from a polymeric material capable of absorbing a substantial portion of said blowing agent molecules emitted from said insulation; and (3) a layer containing a material capable of reacting with a substantial portion of said blowing agent emitted from said insulation.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A device for containing item(s) or fluid(s) at a temperature below ambient temperature comprising: (a) a container or compartment having an interior space for holding food and/or beverage in a cooled condition and (b) thermal insulation comprising a polymeric material having closed cells therein wherein said cells are formed from and/or contain a blowing agent, said container comprising a liner comprising (i) a first layer thermoformed from ABS resin and having a surface facing toward said interior space; and (ii) at least a second layer having a surface facing away from said interior space and toward said thermal insulating foam, wherein said second layer of said liner is at least one of (1) a layer formed from an amorphous or semi-crystalline polyamide resin having sufficient composition and thickness to substantially inhibit the migration of said blowing agent toward said interior space; (2) a layer formed from a polymeric material capable of absorbing a substantial portion of said blowing agent molecules emitted from said insulation; and (3) a layer containing a material capable of reacting with a substantial portion of said blowing agent emitted from said insulation. 
     
     
         2 . The device of  claim 1  wherein said liner has an average thickness of not greater than about 5 mm. 
     
     
         3 . The device of  claim 1  wherein said liner has an average thickness of not greater than about 2 mm. 
     
     
         4 . The device of  claim 1  wherein said liner has an average thickness of not greater than about 1 mm. 
     
     
         5 . A refrigerator comprising the device of  claim 1 . 
     
     
         6 . A refrigerator comprising the device of  claim 3 . 
     
     
         7 . A freezer comprising the device of  claim 1 . 
     
     
         8 . A freezer comprising the device of  claim 3 . 
     
     
         9 . A vending machine comprising the device of  claim 1 . 
     
     
         10 . A vending machine comprising the device of  claim 3 . 
     
     
         11 . A reach-in cooler comprising the device of  claim 1 . 
     
     
         12 . A reach-in cooler comprising the device of  claim 3 . 
     
     
         13 . A transport refrigeration unit comprising device of  claim 1 . 
     
     
         14 . A transport refrigeration unit comprising device of  claim 3 . 
     
     
         15 . The device of  claim 1  wherein said blowing agent comprises transHFCO-1233zd. 
     
     
         16 . A device for containing item(s) or fluid(s) at a temperature below ambient temperature comprising: (a) a container or compartment having an interior space for holding food and/or beverage in a cooled condition and (b) thermal insulation comprising a polymeric material having closed cells containing a blowing agent comprising at least about 50% by weight of trans1-chloro-3,3,3-trifluoropropene (1233zd(E)), said container comprising a liner comprising (i) a first layer comprising ABS polymer and having a surface facing toward said interior space; and (ii) at least a second layer having a surface facing away from said interior space and toward said thermal insulating foam, wherein said second layer is at least one of (1) a layer formed from an amorphous or semi-crystalline polyamide resin having sufficient composition and thickness to substantially inhibit the migration of said blowing agent toward said interior space; (2) a layer formed from a polymeric material capable of absorbing a substantial portion of said blowing agent molecules emitted from said insulation; and (3) a layer containing a material capable of reacting with a substantial portion of said blowing agent emitted from said insulation. 
     
     
         17 . The device of  claim 16  wherein said blowing agent comprises at least about 75% by weight of transHFCO-1233zd. 
     
     
         18 . The device of  claim 16  wherein said blowing agent consists essentially of transHFCO-1233zd. 
     
     
         19 . The device of  claim 17  wherein said first layer is a layer of thermoformed ABS. 
     
     
         20 . The device of  claim 19  wherein said second layer comprises polyamide.
