Abstract
A device and system for determining the status of the contents of a container by measuring the period of time which has elapsed since the opening of the container. The present invention provides a flexible mechanism for enabling the user to determine the usability or efficacy of the contents of the container, since such contents typically experience a higher rate of degradation once the container has been opened. Furthermore, the manufacturer is able to provide information related to the expiration date of an unopened container at the time of manufacture, but cannot determine the time at which the container is opened, and hence the expiration date after opening.
Claims21
A device for measuring elapsed time after a container is opened, comprising:
- (a) a seal for being broken when the container is opened;
- (b) a detector for detecting opening of the container;
- and
- (c) a timer activated by said detector after the container is opened, such that said timer starts to measure the elapsed time after being activated by said detector after said seal is broken, wherein said timer measures the total elapsed time after the container is first opened.
A system for monitoring a container after opening, comprising:
- (a) a seal for being broken when the container is opened;
- (b) a detector for detecting opening of the container;
- (c) a timer activated by said detector after the container is opened, such that said timer starts to measure the elapsed time after being activated by said detector after said seal is broken, wherein said timer measures the total elapsed time after the container is first opened;
- and
- (d) an analyzer for receiving data from said timer concerning the elapsed time and for triggering at least one event after the elapsed time passes a threshold.
A system for monitoring a container after opening, comprising:
- (a) a detector for detecting opening of the container;
- (b) a timer activated by said detector after the container is opened, such that said timer starts to measure the elapsed time after being activated by said detector;
- (c) a transmitter for transmitting data from said timer, wherein said timer, said transmitter and said detector are contained in a single unit;
- and
- (d) a remote computational device for receiving said data.
A device for measuring elapsed time after a container is opened, comprising:
- (a) a detector for detecting opening of the container, said detector comprising a first electronic circuit for being broken upon opening of the container and a second electronic circuit for being formed upon breaking of said first electronic circuit;
- and
- (b) a timer activated by said detector after the container is opened by formation of said second electronic circuits such that said timer starts to measure the elapsed time after being activated by said detector.
