Abstract

A shelf life inference system comprising a container for a plurality of items. The container has coupled to it a tracker operative to read the ID label on each item and to track the exit from and the return to the container of each item separately and to calculate the freshness status of each item upon return to the container.

1 . A system for tracking the freshness state of each of a plurality of perishables associated with a container, comprising an ID label attached to each of said perishables, a tracking device, being responsive to the movement of an ID label exiting or entering a container for updating the shelf life data for the Perishable corresponding to said ID label, said tracking device comprising software operative to calculate the time away from and shelf life used for a perishable while away said container. 
     
     
         2 . A system as in  claim 1 , wherein said container has an access door. 
     
     
         3 . A system as in  claim 1 , wherein said container is a liner.

         5 . A system as in  claim 1 , wherein shelf life monitoring of perishables inside of the container is by zone location. 
     
     
         6 . A system as in  claim 1 , wherein said plurality of perishables associated with the container have varying shelf lives. 
     
     
         7 . A system as in  claim 1 , wherein shelf life calculation for the plurality of perishables is represented as a percentage of life “-left” and “-used” and is based upon the life of the perishable as starting at 100 and ending at 0, the use-by end of life of the perishable. 
     
     
         8 . A system as in  claim 7  wherein the end of life is the perishable's “after when opened” date.
