  • Patent number: 4953763
    Abstract: An animal scent dispensing apparatus includes a housing that can be supported in an elevated position above the ground. A reservoir is supported by the housing for containing an animal scent to be dispensed. An outlet releases fluid scent from the reservoir in a drip-like fashion so that it can be dispensed to fall to the ground. A valved vacuum line operable between open and closed flow positions and communicates with the reservoir for maintaining a vacuum on the reservoir when not dispensing fluid therefrom. A timed valving mechanism fence the reservoir at the vacuum line so that fluid in the reservoir will dispense from the outlet and the outlet defines at least in part the dispensing flow rate as a fluid dispensed from the reservoir. The apparatus has particular utility for deer hunting wherein a scent can be dispensed at multiple times during the day for very short time periods of for example a few seconds.
