Patent ID: 8790110

Claim:
A one-piece completely disposable device for use in cooking, adapted to dispense food material therefrom in a controlled manner for preparing, filling, assembling and decorating purposes and to then be discarded, said device comprising: an elongated envelope having: (A) a side wall; (B) a first end for inserting such food material into said envelope; and (C) a distal second end having an integral, discharge orifice having an opening for discharging such food material from said envelope through said orifice 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 it passes through said orifice upstream of said opening; wherein said orifice further having: (iii) an axis with a length and running parallel to a flow of such food material through said orifice; and (iv) varying cross sectional dimensions along the length of the said axis; said orifice being manufactured from an elastic material configured to allow said orifice to be initially cut at an initial cutline along the length of said axis of said orifice in order to permit said opening of said orifice to have a desired opening size with a predetermined cross-sectional dimension and to be further cut at further cutlines to permit selection of the desired opening size and to control dispensing a greater amount of the food material out-through the discharge orifice, without interfering with an operation of said protrusions while retaining a treatment capacity of the orifice.
