Abstract

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

First claim

The invention claimed is:

1. A quality management system for products comprising:
a multiplicity of barcode indicators each configured to provide a machine-readable indication of exceedance of at least one threshold by at least one product quality determining parameter, said multiplicity of barcode indicators being configured to provide said machine-readable indication only following actuation thereof, each of said multiplicity of barcode indicators comprising:
a barcode comprising black areas and transparent areas;
a pull strip, said pull strip being suitable to prevent the passage of solvents and coloring agents therethrough before removal thereof; and
a colored area, said colored area disposed behind said pull strip, and said actuation comprises removal of said pull strip;

a barcode indicator reader configured to read said barcode indicators and to provide output indications; and
an indication interpreter configured to receive said output indications and to provide human sensible, product unit specific, product quality status outputs.

2. The quality management system according to claim 1 and wherein prior to said actuation, said barcode indicator is in a first visible state and following said actuation said barcode indicator is in a second visible state, different from said first visible state.

3. The quality management system according to claim 2 and wherein said indicator is not barcode reader-readable when said barcode indicator is in said first visible state.

4. The quality management system according to claim 2 and wherein said indicator is barcode reader-readable when said barcode indicator is in said first visible state.

5. The quality management system according to claim 2 and wherein removal of said pull strip renders portions of said colored area readable through said transparent areas in said barcode and wherein portions of said colored area appear similarly to said barcode in said first visible state and can be read together therewith as a single barcode in said second visible state.

6. The quality management system according to claim 1 and wherein said pull strip comprises a polyester pull strip.

7. The quality management system according to claim 1 and wherein said multiplicity of barcode indicators is configured to provide said machine-readable indication only upon activation thereof which occurs automatically a predetermined time following actuation thereof.

8. The quality management system according to claim 1 and wherein each of said multiplicity of barcode indicators provides a first machine-readable indication prior to said exceedance of said at least one threshold and a second machine-readable indication following said exceedance of said at least one threshold, said first and second machine-readable indications having identical check sum digits.

9. The quality management system according to claim 1 and wherein said indication interpreter comprises a server communicating with said barcode indicator reader and providing at least one of a price indication, a shelf-life indication and a salability output indication.

10. The quality management system according to claim 1 and wherein each of said multiplicity of barcode indicators is configured to provide multiple machine-readable indications for exceedance of multiple ones of said thresholds.
