A pet feeding device composed of a horizontally upright serving container having an opening in its upper end and an inverted feed-supply container having an opening in its lower end, wherein the open ends are axially inserted in overlapped position and then attached to one another in response to relative movement between the containers transversely of the axes of insertion. A pair of tongue-and-groove assemblies or joints are employed to guide the containers during the relative transverse movement, the tongue component of each joint being integral with the overlapped end of one of the containers and the groove component integral with the proximate overlapped end of the other container. By moving the supply container transversely and rearwardly from its axially inserted position, the tongue components of the joints intermesh progressively mesh with the groove components until the supply container reaches its normal position of use at the rear portion of the serving container. Conversely, by moving the supply container in the opposite direction toward its axially inserted position, the components are unmeshed progressively to disengage it from the supply container.

In a pet feeder of flowable materials, a horizontally disposed serving container (11) provided with a bottom (9), front and rear walls (11b, 11c) and a pair of substantially vertical oppositely disposed sidewalls (11a, 11a), the upper margins of said walls defining an opening (12) in the upper end of the container, and an inverted supply container (14) provided with front and rear walls (14b, 14c) and a pair of substantially vertical oppositely disposed sidewalls (14a, 14a) relatively shorter than the sidewalls of said first opening, the lower margins of the inverted container defining an opening (15) in its lower end, said oppositely disposed sidewall margins of the inverted container being vertically overlapped respectively by and in laterally spaced relation to said oppositely disposed segments of the serving container sidewall margins to thereby provide a passageway between the container ends, in combination with a pair of tongue-and-groove joints (18, 18) respectively connecting said oppositely disposed sidewall margins of the inverted container (14) to said overlapping sidewall segments of the serving container (11), said joints slidably supporting the inverted container upon the serving container and for movement along a path extending forwardly and rearwardly of the feeder, the tongue component (22) of each of said joints (18, 18) being integral with and projecting laterally from one of said connected overlapping sidewall margins and the associated groove component (20) being integral with the other of said connected overlapping sidewall margins and laterally intermeshing with said tongue component (22), each of said joints (18, 18) converging rearwardly and laterally inwardly at an acute angle a relative to said path to cause its tongue and groove components to unmesh longitudinally and laterally, progressively in response to forward movement of the supply container, and conversely, to cause the components to intermesh longitudinally and laterally, progressively in response to rearward movement of the supply container.
