A one-piece completely disposable device for use in cooking, adapted for dispensing food material which contain lumps therefrom in a controlled manner for filling and decorating purposes, said device comprising: a one-piece envelope having: (A) a side wall; and (B) an integral, discharge orifice having an opening through which such food material can exit said envelope upon application of external pressure to said side wall; said orifice having: (i) an internal wall; and (ii) protrusions extending inwardly from said internal wall for treating such food material as said food material passes through said orifice upstream of said opening; said orifice being manufactured from an elastic material for allowing said orifice to be deformed in order to facilitate passage of such food material through said orifice despite the presence of lumps within such food material, and for the orifice to be able to apply a pressure to the lumps to break up the lumps, so that they pass through the orifice, and then the orifice returns to its original size and shape.
