US Patent 9545175 Food processor with attachment

A blending apparatus is provided which includes a container defining a cavity having a center axis and a substantially rectangular cross section through the center axis. The blending apparatus further includes a lid to cover the cavity defined by the container, and an attachment to fit within the cavity and rotate about the center axis of the cavity. In some arrangements, a set of sides of the container defines (i) a substantially octagonal interior cross section through the center axis at a location adjacent a bottom of the container to prevent lodging of food products at the bottom of the container when the attachment rotates within the cavity; and (ii) a substantially square interior cross section through the center axis at a location further from the bottom of the container.
