Abstract:
1. An on-demand animal feed apparatus comprising: a receiving chamber configured to transfer animal feed from a feed supply to a feed reservoir, the receiving chamber comprising an upper section to connect to the feed supply, a lower section, and an intermediate section disposed between the upper and lower sections; a base tube connected to the lower section of the receiving chamber, the base tube having an upper portion that cooperates with the receiving chamber to define the feed reservoir, and a lower portion defining a discharge opening for dispensing animal feed; and an elongated actuator disposed at least partially within the base tube along a length of the base tube and having a distal end extending out of a distal end of the base tube to an exterior of the apparatus, the actuator being configured to raise and lower in an axial direction in response to direct contact of the distal end of the elongated actuator and movement of the actuator by an animal, thereby allowing an on-demand transfer of the animal feed from the feed reservoir through the discharge opening, wherein, even when feed is provided in the receiving chamber to a level above the lower section, the lower section of the receiving chamber includes a relief area defining a void above the actuator where no feed is present between movements of the actuator by the animal, and wherein the relief area enables a temporary upward displacement of the animal feed into the void of the relief area when the actuator is raised, wherein the receiving chamber restricts passage of the elongated actuator through the receiving chamber and the base tube restricts passage of the elongated actuator through the base tube, wherein the receiving chamber includes a coupling member and the base tube includes a cooperating coupling member, and wherein the coupling member and cooperating member releasably couple the receiving chamber to the base tube to permit insertion and removal of the elongated actuator from the base tube when the base tube is uncoupled from the receiving chamber, and wherein the receiving chamber comprises a cylindrical outer wall and the lower section of the receiving chamber comprises an inner delivery tube inside of and substantially concentric with the cylindrical outer wall.
