System and method for improved quality management in a product logistic chain
First Claim
1. A product container operative to provide a machine-readable indication of exceedence of at least one threshold by at least one product quality determining parameter, said product container comprising:
- a machine-readable indicator located within said product container, said machine-readable indicator having a first machine-readable state, prior to exceedence of said at least one threshold, and at least one second machine-readable state, following exceedence of said at least one threshold, said machine-readable indicator including;
a machine-readable code defining layer, defining a machine-readable indicator in said first readable state;
a plurality of transparent areas, which, when colored, define, together with said machine-readable code defining layer, said at least one second machine-readable state;
at least one coloring element;
an opaque layer disposed intermediate said machine-readable code defining layer and said at least one coloring element; and
at least one coloring agent located on said at least one coloring element, said at least one coloring agent operative to diffuse through said opaque layer following exceedance of said at least one threshold; and
a transparent portion formed in said product container for viewing said machine-readable indicator.

Abstract
A quality management system for products including a multiplicity of product unit specific indicators, each operative to provide a machine-readable indication of exceedence of at least one threshold by at least one product quality determining parameter, an indicator reader operative to read the product unit specific indicators and to provide output indications and a product type specific indication interpreter operative to receive the output indications and to provide human sensible, product unit specific, product quality status outputs.

4. A quality management system for products comprising:
-
a multiplicity of product containers each operative to provide a machine-readable indication of exceedence of at least one threshold by at least one product quality determining parameter, each of said product containers comprising; a machine-readable indicator located within said product container, said machine-readable indicator having a first machine-readable state, prior to exceedence of said at least one threshold, and at least one second machine-readable state, following exceedence of said at least one threshold, said machine-readable indicator including; a machine-readable code defining layer, defining a machine-readable indicator in said first readable state; a plurality of transparent areas, which, when colored, define, together with said machine-readable code defining layer, said at least one second machine-readable state; at least one coloring element; an opaque layer disposed intermediate said machine-readable code defining layer and said at least one coloring element; and at least one coloring agent located on said at least one coloring element, said at least one coloring agent operative to diffuse through said opaque layer following exceedance of said at least one threshold; and a transparent portion formed in said product container for viewing said machine-readable indicator; an indicator reader operative to read said machine-readable indicators and to provide output indications; and a product type specific indication interpreter operative to receive said output indications and to provide human sensible, product specific, product quality status outputs.

5. A method for quality management for products comprising:
-
employing a multiplicity of product containers, each operative to provide a machine-readable indication of exceedence of at least one threshold by at least one product quality determining parameter, each of said product containers comprising; a machine-readable indicator located within said product container, said machine-readable indicator having a first machine-readable state, prior to exceedence of said at least one threshold, and at least one second machine-readable state, following exceedence of said at least one threshold, said machine-readable indicator including; a machine-readable code defining layer, defining a machine-readable indicator in said first readable state; a plurality of transparent areas, which, when colored, define, together with said machine-readable code defining layer, said at least one second machine-readable state; at least one coloring element; an opaque layer disposed intermediate said machine-readable code defining layer and said at least one coloring element; and at least one coloring agent located on said at least one coloring element, said at least one coloring agent operative to diffuse through said opaque layer following exceedance of said at least one threshold; and a transparent portion formed in said product container for viewing said machine-readable indicator; reading said machine-readable indicators and providing output indications therefrom; and interpreting said output indications to provide human sensible, product unit specific, product quality status outputs.
