Abstract: A container defines a central longitudinal axis and includes an engagement part that secures a lid to the container. A neck portion is disposed adjacent the engagement part and includes a plurality of recessed portions spaced circumferentially around the neck portion, where each recessed portion has a periphery. The neck portion also includes an outwardly protruding rib disposed along at least a portion of the periphery of at least one recessed portion and an outer surface extending between each pair of adjacent recessed portions. The rib projects outwardly from both the outer surface and the at least one recessed portion.

Abstract: A process for selectively grinding dual-density processed food in a single unit operation in a short-duration manner. Selective grinding as between lower-density and higher-density portions of the dual-density processed food may be effected without the need for moving mechanical parts. A granulated lower-density portion and liberated nonground higher-density portion obtained from the selective grinding treatment performed on dual-density processed food are independently useful for re-use in food production lines.
