  • Patent number: 5887749
    Abstract: A food container especially for pet feeding has a plurality of compartments at least one compartment of which is circular to house canned wet food. The inside walls of the compartments include a upper rim wall portion set back at a rim wall base elevation between the compartment floors and the container top surface that is the same in all compartments. The setback provides a continuous shoulder lining each compartment adjacent the rim wall base. A lid for the container has at least one closed course protrusion raised in the underside of the lid. The protrusion has peripheral shape and outside dimensions sufficiently corresponding to the peripheral shape and internal dimensions of the rim walls of the circular and the other of the compartments, to interferingly nest the protrusion within the circular and other compartments above the shoulder of the compartments.
