Disposable food product transport box and ice pouch

Abstract

A bag for dry ice includes a container having a chamber therein for receiving the dry ice; a first layer of insulation at the chamber constructed and arranged to provide a first heat transfer rate; and a second layer of insulation at the chamber spaced apart from the first layer of insulation, and constructed and arranged to provide a second heat transfer rate greater than the first transfer rate. A related method is also provided.

What is claimed is: 
     
         1 . A bag for dry ice, comprising:
 a container having a chamber therein for receiving the dry ice:   a first layer of insulation at the chamber constructed and arranged to provide a first heat transfer rate; and   a second layer of insulation at the chamber spaced apart from the first layer of insulation, and constructed and arranged to provide a second heat transfer rate greater than the first transfer rate.   
     
     
         2 . The bag of  claim 1 , further comprising a top constructed and arranged to seal the chamber with the dry ice therein. 
     
     
         3 . The bag of  claim 1 , further comprising a first side all positioned to support the first layer, a second sidewall positioned to support the second layer, and at least one vent hole in the second sidewall for permitting vapor from the dry ice to be exhausted from said chamber. 
     
     
         4 . The bag of  claim 1 , wherein the container and the first and second layers are constructed of flexible material. 
     
     
         5 . The bag of  claim 1 , further comprising a transport container having a space therein for receiving the bag, and a cover to close-off the space when the bag is disposed therein. 
     
     
         6 . The bag of  claim 5 , wherein the transport container is constructed of cardboard. 
     
     
         7 . The bag of  claim 6 , wherein the cardboard comprises a substance to facilitate biodegradation of said cardboard. 
     
     
         8 . The bag of  claim 1 , wherein the first and second layers of insulation each comprise bubble wrap. 
     
     
         9 . The bag of  claim 5 , wherein the transport container comprises a plurality of compartments, each one of said plurality of compartments sized and shaped to receive a corresponding bag. 
     
     
         10 . The bag of  claim 5 , wherein the transport container comprises insulation material lining the space. 
     
     
         11 . The bag of  claim 10 , wherein the insulation material is selected from the group consisting of bubble wrap, high density foam, and a combination thereof. 
     
     
         12 . A dry ice bag for transporting groceries, comprising:
 a flexible pouch having a space therein for containing dry ice;   a plurality of insulation liners in the space, each of said insulation liners providing a separate and distinct heat transfer rate; and   at least one hole in the flexible pouch proximate one of the plurality of insulation liners having a lowest heat transfer rate and through which vapor form the dry ice may be exhausted from space   
     
     
         13 . The dry ice bag of  claim 12 , further comprising an opening to the space, said opening sealed closed after the dry ice is delivered into said space. 
     
     
         14 . A method of providing heat transfer for products to be transported, comprising:
 positioning the product for transport;   providing a container having a chamber therein for receiving the dry ice, a first layer of insulation at the chamber constructed and arranged to provide a first heat transfer rate, and a second layer of insulation at the chamber spaced apart from the first layer of insulation, and constructed and arranged to provide a second heat transfer rate greater than the first transfer rate; and   orientating the container with one of the first and second layers facing the product.   
     
     
         15 . The method of  claim 14 , wherein the providing further comprises determining an amount of the dry ice to be received in said chamber. 
     
     
         16 . The of  claim 15 , further comprising sealing the chamber dosed after the receiving of said dry ice in said chamber. 
     
     
         17 . The method of  claim 14 , wherein the products comprise groceries. 
     
     
         18 . The method of  claim 14 , further comprising transporting the container to a remote location for receipt of the products and returning the container for subsequent use. 
     
     
         19 . The method of  claim 14 , wherein the orientating comprises contacting the container with the products.
