  • Apparatus containing time-sensitive fluid with an indication as to the state of the fluid
    Patent number: 5229751
    Abstract: A perishable fluid container assembly is disclosed as including a timing mechanism in conjunction with a coffee pot, wherein a visible indicator device is energized while the coffee within the pot remains fresh. When the coffee pot is filled with fresh coffee, the visible indicator device first becomes energized, and stays energized even though the coffee pot is temporarily tipped on its side for the dispensing of coffee. After the predetermined time duration has expired, the visible indicator device is de-energized to indicate that the character or freshness of the coffee has expired. Additionally if the coffee pot becomes empty, the visible indicator device becomes de-energized after a short time delay.
