Abstract

System and method for enabling accurate spoilage monitoring of a liquid food product or the like from the moment it is created, until the time it is either consumed or needs to be discarded. In a preferred embodiment of the invention, a container for the food product, or a device to be attached to a container, is equipped with a switch, thermometer, other environmental sensors, controller and alarm. The switch is activated automatically or manually at the moment when the liquid food product is created, and then the temperature and other environmental parameters of the food product are monitored during the subsequent course of time, all the while keeping track of the temperature history of the product throughout the period, until the controller calculates that the maximum safe period has expired; whereupon an alarm is activated to warn the user to discard the product.

Claims

1. A device for holding and mixing perishable products while providing anti-spoilage monitoring, said device comprising:

at least a portion of a container;

a compartment capable of holding a material desired to be mixed with a liquid prior to use;

a seal for maintaining said material within said compartment prior to use;

an actuating element causing said seal to open using one of a direct mechanical connection and an electrical actuation of a motor, and said material to become in mutual association with said liquid, thereby forming mixed contents within said container; and

a controller configured to receive a signal responsive to one or more of said actuating element and a start/stop button indicating commencement of mixing, initiate a timer, perform a calculation on a recurring basis as to the degree of spoilage of the mixed contents in part based on the status of said timer, and actuate an alarm when the calculation determines that the mixed contents have reached a spoilage condition.

2. The device of claim 1, further comprising at least one sensor capable of generating a signal based on a characteristic parameter of the mixed contents, and wherein the calculation of the degree of spoilage is based in part on the timer and in part on the signal corresponding to the characteristic parameter.

3. The device of claim 2, wherein the characteristic parameter corresponds to at least one of the following parameters:

the temperature of the container contents, the ambient temperature surrounding the container, the chemical composition of the mixed contents, the pH of the mixed contents, the ambient light level.

4. The device of claim 1, wherein said seal comprises at least one of a valve and a frangible element.

5. The device of claim 1, wherein said controller has the capacity to be programmed to calculate spoilage based on a plurality of spoilage algorithms, and the desired algorithm to be used may be selected by the user.

6. The device of claim 5, wherein at least one of said spoilage algorithms may be installed in said controller by means of an external device and a communication link.

7. The device of claim 5, wherein at least one of said spoilage algorithms corresponds to a “

non-mixed”

setting.

8. The device of claim 1, wherein said step of actuating an alarm comprises sending a coded signal to an external device through a communication link.

9. The device of claim 1, wherein said controller can send information pertaining to operating parameters and cumulative statistics to an external device through a communication link.

10. The device of claim 1, wherein said container comprises a baby bottle.

11. The device of claim 1, wherein said portion of a container comprises a ring that may be assembled along with a container base to form a baby bottle.

12. A device to enable holding and mixing of perishable food products while providing anti-spoilage monitoring, and which can be attached to a baby bottle or portion thereof, said device further comprising:

a compartment capable of holding a material desired to be mixed with a liquid prior to use;

a seal for maintaining said material within said compartment and said liquid in said baby bottle prior to use;

an actuating element causing said seal to open using one of a direct mechanical connection and an electrical actuation of a motor, and said material to become in mutual association with said liquid, thereby forming mixed contents within said baby bottle; and

a controller configured to receive a signal responsive to one or more of said actuating element and a start/stop button indicating commencement of mixing, initiate a timer, perform a calculation on a recurring basis as to the degree of spoilage of the mixed contents in part based on the status of said timer, and actuate an alarm when the calculation determines that the mixed contents have reached a spoilage condition.

13. The device of claim 12, further comprising at least one sensor capable of generating a signal based on a characteristic parameter of the mixed contents, and wherein the calculation of the degree of spoilage is based in part on the timer and in part on the signal corresponding to the characteristic parameter.

14. The device of claim 13, wherein the characteristic parameter corresponds to at least one of the following parameters:

the temperature of the container contents, the ambient temperature surrounding the container, the chemical composition of the mixed contents, the pH of the mixed contents, the ambient light level.

15. The device of claim 12, wherein said seal comprises at least one of a valve and a frangible element.

16. The device of claim 12, wherein said controller has the capacity to be programmed to calculate spoilage based on a plurality of spoilage algorithms, and the desired algorithm to be used may be selected by the user.

17. The device of claim 16, wherein at least one of said spoilage algorithms may be installed in said controller by means of an external device and a communication link.

18. The device of claim 16, wherein at least one of said spoilage algorithms corresponds to a “

non-mixed”

setting.

19. The device of claim 12, wherein said step of actuating an alarm comprises sending a coded signal to an external device through a communication link.

20. The device of claim 12, wherein said controller can send information pertaining to operating parameters and cumulative statistics to an external device through a communication link.

21. A method for holding and mixing perishable products while providing anti-spoilage monitoring, said method comprising:

providing a compartment capable of holding material desired to be mixed with a liquid prior to use;

providing a seal for maintaining said material within said compartment prior to use;

providing an actuating element which can cause said seal to open using one of a direct mechanical connection and an electrical actuation of a motor, and said material to become in mutual association with said liquid to be mixed, thereby forming mixed contents; and

providing a controller configured to receive a signal responsive to one or more of said actuating element and a start/stop button indicating commencement of mixing, initiate a timer, perform a calculation on a recurring basis as to the degree of spoilage of the mixed contents in part based on the status of said timer, and actuate an alarm when the calculation determines that the mixed contents have reached a spoilage condition.
