摘要 A device is disclosed for dispensing food particles at a controlled rate in which a container is used having an aperture located on one side of the container. A tube is attached to the aperture such that food can pass through the tube, then through the aperture and be expelled outside the container. The aperture defines a longitudinal axis coinciding with the axis of the tube. The gap between the tube and an end portion of the device is predetermined to control the rate of consumption of the food particles being expelled from the container.
