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.

Claims

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, each of said multiplicity of barcode indicators comprising a pull strip, each of said multiplicity of barcode indicators being operative to provide said machine-readable indication only following actuation thereof, said actuation comprising removal of said pull strip;

a barcode indicator reader operative to read said barcode indicators and to provide output indications; and

an indication interpreter operative to receive said output indications and to provide human sensible, product unit specific, product quality status outputs.

2. A 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, and wherein said indicator is barcode reader-readable at least in said second visible state.

3. A 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. A 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. A quality management system according to claim 1 and wherein said pull strip is suitable to prevent the passage of solvents and coloring agents therethrough before removal thereof.

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

7. A 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.

8. A 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.

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