Abstract

They object of the present invention is an TIME MANAGEMENT SYSTEM that integrates a static barcode together with a TIME VARIABLE label referred as TIME VALUE BAR or TVB. The TVB is then linked via a database to product information that vary with time such as useful shelf life, remaining shelf life, price, identity, and expiration of the article. The information is input, stored, linked, output, and managed by a Central Processing Unit (CPU), but it is also partially available to the public via the TVB. In one of the preferred embodiments of the invention the variable bar code system is compatible with the Universal Product Code (UPC) currently in use in most retail shops. In another embodiment the TIME VALUE BAR of the present invention relates a 3D barcode with a VARIABLE TIME label effectively adding a fourth dimension to the barcode thus becoming a 4D barcode system.

Claims

1. A label for delivering information regarding an item, the label comprising:

a common base member;

two separate components, including a first component and a second component, displayed simultaneously on said common base member;

said common base member having an adhesive surface to be attached to the item and a display surface supporting said two separate components on display;

said first component being a time invariable component displaying a first set of printed indicia that does not change over time;

said second component being a time variable component, containing;

a printable layer;

a second set of printed indicia printed on said printable layer;

a chemicals embedded layer composed of an absorbent material embedding a color changing compound selected from the group consisting of organic color changing compounds, inorganic color changing compounds, and their combinations;

a permeable layer internally subdivided into a plurality of areas physically separated one from the other one ; and

a sealant layer;

said two separate components being assembled such that said printable layer lays on said common base member, and said sealant layer is exposed to open air.

2. The label according to claim 1, wherein said first set of printed indicia displayed on said time invariable component is a barcode selected from the group consisting of a linear barcode, a matrix barcode, and a three dimensional barcode.

3. The label according claim 2, wherein said barcode is a G.S.-1 linear barcode U.P.C. compliant.

4. The label according to claim 1, wherein said second set of printed indicia impressed on said printable layer of said time variable component display information that is clear an observer to read and understand.

5. The label according to claim 1, wherein said second set of printed indicia impressed on said printable layer of said time variable component display information that is encoded.

6. The label according to claim 1, wherein said color changing compound is hydroquinone or a compound deriving from or containing the quinone and hydroquinone functional groups.

7. The label according to claim 1, wherein said second set of printed indicia impressed on said printable layer of said time variable component is progressively canceled out by a change in color caused by a reaction of said color changing compound with an atmospheric component comprises molecular oxygen, an oxide of nitrogen, or an oxide of carbon.

8. The label according to claim 7, wherein a chemical present in the air is a chemical that has an effect on pH.

9. The label according to claim 8, wherein said permeable layer allows a certain amount of chemicals present in the air to get in contact with said color changing compound at a certain pre-set rate.

10. The label according to claim 9, wherein said pre-set rate allows for a total discoloration of said barcode in a time interval comprised between one day and ten years.

11. The label according to claim 1, wherein said permeable layer is a zeolite based molecular sieve.

12. The label according to claim 1, wherein said oxide of carbon is selected from the group consisting of carbon monoxide and carbon dioxide.

13. A time management system associated with a product, the time management system comprising:

a label for delivering information regarding the product, the label containing a common base member, two separate components, including a first component and a second component, that does change over time, displayed simultaneously on said common base member, said common base member having an adhesive surface to be attached to the product and a display surface supporting said two separate components on display, said first component being a time invariable component displaying a first set of printed indicia that does not change over time, said second component being a time variable component, containing;

a printable layer, a second set of printed indicia printed on said printable layer, a chemicals embedded layer composed of an absorbent material embedding and a color changing compound selected from the group consisting of organic color changing compounds, inorganic color changing compounds and their combination, a permeable layer internally subdivided into a plurality of areas physically separated one from the other one, and a sealant layer, said two separate components being assembled such that said printable layer lays on said common base member, and said sealant layer is exposed to open air;

a central processing unit (CPU);

a plurality of input devices;

a plurality of output devices;

a plurality of connections to link said CPU to said input and output devices;

a first database coupled to said CPU;

a second database coupled to said CPU; and

a computer software program to manage the information.

14. The time management system according to claim 13, wherein said plurality of connections to link said input and output devices is wireless.

15. The time management system according to claim 13, wherein said input devices are selected from the group consisting of keyboards, mice, and optical scanners.

16. The time management system according to claim 13, wherein said output devices are selected from the group consisting of monitors, printers, smart phones, and cash registers.
