Abstract

A refrigerator includes at least one refrigerated compartment and a food product management system. The food product management system includes a container for storing foodstuffs in the at least one refrigerated compartment. The container includes a storage zone and a lid. A tag is arranged on the container to provide a consumer with an indication of whether a food item stored in the container is or is not spoiled. The tag can include a timer having a display, an indicator that changes state upon the passage of a predetermined time period and a computer that notifies a consumer, such as through an email, about a parameter associated with the food item in the container. The tag is affixed to the container with adhesive, snaps, clips, hooks and the like or, alternatively, simply integrally formed with the container.

Claims

1. A refrigerator comprising:

a cabinet shell;

a liner arranged within the cabinet shell defining at least one refrigerated compartment; and

a food product management system including;

a container including a lid for storing foodstuffs in the at least one refrigerated compartment;

a tag provided on the container for indicating a storage duration of a food product placed in the container;

a timer operatively associated with the tag, said timer counting a passage of at least one of days, hours and minutes, said timer being activated upon reaching a predetermined temperature, which is below ambient temperature, and deactivated upon reaching a temperature above the predetermined temperature;

a computer operatively connected to the internet;

an RFID detector operatively connected to the computer;

an RFID unit located on the tag and containing information pertaining to at least one foodstuff parameter wherein, upon being placed in a refrigerator, said RFID unit is scanned by the RFID detector for the at least one foodstuff parameter, said computer being adapted to automatically generate an email notification to a consumer regarding the least one foodstuff parameter after a certain period of time on the timer has elapsed; and

an indicator arranged on the tag signaling passage of a predetermined time period, said indicator changing from a first state prior to the predetermined time period lapsing, to a second state upon reaching the predetermined time period.

2. A refrigerator comprising:

a cabinet shell;

a liner arranged within the cabinet shell defining at least one refrigerated compartment; and

a food product management system including;

a tag for indicating a storage duration of a food product;

a timer operatively associated with the tag, said timer counting a passage of at least one of days, hours and minutes, said timer being activated upon reaching a predetermined temperature which is below ambient temperature and deactivated upon reaching a temperature above the predetermined temperature; and

an indicator arranged on the tag signaling passage of a predetermined time period, said indicator changing from a first state prior to the predetermined time period lapsing, to a second state upon reaching the predetermined time period.

3. The refrigerator according to claim 2, wherein the indicator is constituted by a display presenting a numeric representation of at least one of days, hours and minutes.

4. The refrigerator according to claim 2, further comprising:

a plurality of control elements arranged upon the tag, said plurality of control elements being adapted to program the timer with the predetermined time period.

5. The refrigerator according to claim 2, wherein the indicator is constituted by a plurality of lights, each of the plurality of lights being illuminated to progressively signal passage of the predetermined time period.

6. The refrigerator according to claim 5, wherein the tag includes a plurality of control elements, said plurality of control elements being adapted to program the timer with the predetermined time period.

7. The refrigerator according to claim 6, wherein the tag includes a display for reviewing the predetermined time period input through the plurality of control elements.

8. The refrigerator according to claim 2, further comprising:

a controller provided in the tag and operatively connected to the timer; and

a temperature sensor operatively connected to the controller, said temperature sensor being adapted to sense the predetermined temperature and signal the controller to activate the timer.

9. A refrigerator comprising:

a cabinet shell;

a liner arranged within the cabinet shell defining at least one refrigerated compartment; and

a food product management system including;

a tag for indicating a storage duration of a food product;

a computer operatively connected to the internet;

an RFID detector operatively connected to the computer; and

an RFID unit located on the tag and containing information pertaining to at least one foodstuff parameter wherein, upon being placed in a refrigerator, said RFID unit is scanned by the RFID detector for the at least one foodstuff parameter, said computer being adapted to automatically generate an email notification to a consumer regarding the least one foodstuff parameter.

10. The refrigerator according to claim 9, further comprising:

a plurality of control elements arranged upon the tag, said plurality of control elements being adapted to program the RFID device with the at least one foodstuff parameter.

11. The refrigerator according to claim 10, further comprising:

a display for reviewing the at least one foodstuff parameter input through the plurality of control elements.

12. The refrigerator according to claim 11, wherein the at least one foodstuff parameter is constituted by an expiration date associated with a particular food item.

13. The refrigerator according to claim 9, further comprising:

a bar code scanner supported by the cabinet shell; and

a bar code provided on the tag, said bar code containing the at least one foodstuff parameter.

14. A method of tracking an expiration date of a food item placed in a refrigerator comprising:

programming a controller with the expiration date, said controller being provided in a tag adapted to be attached to the food item;

activating a timer to count a time period corresponding to the expiration date, said timer being activated only upon the tag reaching a predetermined refrigerated temperature; and

indicating that the food item has reached the expiration date.

15. The method of claim 14, wherein indicating that the food item has reached the expiration date is constituted by indicating passage of at least one of days, hours and minutes on a numeric display.

16. The method of claim 14, wherein indicating that the food item has reached the expiration date is constituted by activating at least one indicator light.

17. The method of claim 14, wherein indicating that the food item has reached the expiration date includes sequentially activating a plurality of indicator lights as the expiration date approaches.

18. The method of claim 14, wherein the controller is programmed through a plurality of control elements arranged on the tag.

19. The method of claim 14, further comprising:

notifying through an email when the expiration date has arrived.

20. The method of claim 19, further comprising:

scanning an RFID device provided in the tag, said RFID device being programmed with the expiration date.
