Container and blade arrangement for food preparation appliance

A container configured for a food preparation appliance that would utilize a blade member that would be rotatably positioned within the container, the container having a direction of rotation defined by an expected direction of rotation of the blade within the container, the container comprising:

• a bottom end and an open top end,
• a tubular sidewall extending from the bottom end to the top open end and together with the bottom end defining an interior space of the container, the container being configured to accommodate positioning of the blade member within the interior space of the container, the sidewall having a rim at the open end through which contents to be processed by the appliance are loaded into the interior space of the container, the container having a center;
• said sidewall having a plurality of ribs, each rib projecting inward of the interior space of the container and extending heightwise along at least a portion of the sidewall intermediate the open top end and bottom end of the container, the ribs each having, in the direction of rotation of the blade member, a peak defined as the shortest transverse dimension measured from the center of the container to the sidewall at a respective height along the portion of the sidewall having the rib,
• wherein each rib comprises, in the direction of rotation of the blade member, an inflow segment leading to the peak and including a first slope and an outflow segment leading away from the peak and including a second slope, the outflow segment of one rib transitioning directly into the inflow segment of an adjacent rib in the direction of rotation of the blade member.
