A dispenser for pet food kibble or other loose material, where a floor panel of adjustable elevation is contained within the dispenser. The floor panel is supported by a spring that adjusts the height of floor panel in response to removal or addition of material. The spring automatically adjusts to maintain the level of material at a constant elevation. The floor panel is sealed with a gasket to prevent material from falling into the chamber below. A transparent window in the front of the container allows a user to view the amount of material left in the container to determine when the container may be refilled. The opening of the container may have a shape approximate to that of a standard bag of material to be used in the dispenser. The spring may be surrounded by a telescoping rod to prevent buckling under the increased weight of material.
