ABSTRACT:
A creep feeder furnishes a blow molded container with an inner chamber, a top port and a bottom port. The top port provides passage for feed into the inner chamber and is closed by a snap fit cap. The bottom part provides a throat, narrowing valve seat and narrower delivery tube. A blow molded, hollow valve is enclosed in the bottom part and operates with the valve seat to dispense feed upon demand of an animal. The valve has a bulbous head with a gradually narrowing under surface that engages with the valve seat to close the bottom port. A narrower valve stem hangs in the delivery tube, and the delivery tube keeps the valve substantially aligned in the bottom port to insure proper sealing between the head and valve seat. The device dispenses feed upon an animal pushing up the bottom end of the stem and spacing the head from the seat. Feed in the chamber then flows down through the bottom port. An umbrella hanging in the chamber reduces the weight of the feed resting on the valve head to reduce the force needed to push up the valve for dispensing feed.
