  • Animal oral feeding/injecting device
    Patent number: 5524576
    Abstract: An animal feeding or injecting device for orally supplying liquids, slurries, gels, and some solids to an animal. This device consists of a tubular container having a tapered end region and an opposite open end through which a plunger passes. A stop or collar is slidable along the outside of the tubular container which not only restricts the distance the plunger can be inserted within the tubular container, but also prevents the tubular container from being inserted too far within the animal's mouth. A connector is secured to both the stop and the plunger so as to prevent the plunger from being inserted too far within the tubular container.
