DEFINITION

Classification: 99/467

(under the class definition) Device including a chamber surrounding the food, and means associated with the chamber for exposing the food to contact with gaseous matter under conditions other than merely ambient or heated atmospheric conditions.

(1) Note. This subclass relates to an enclosed atmosphere that is modified by a gas or gaseous suspension and the modification is accomplished by more than the single means of heating ambient atmosphere (such as by an oven or similar heated enclosure as found in a heating class such as the class for Stoves and Furnaces). The modification usually involves some feature such as: entrapping smoke around the food, adding flavor or moisture, increasing pressure, etc. Also compare the subclasses in the Search This Class, Subclass notes below.

293+, for a steamer or condenser-type beverage making infusor.

352+, especially subclass 356, for "receptacle filling or closing"

359+, for treatment of food already in a "filled receptacle."

372+, and 426+, for a "heated mold" or "confining, conforming or molding support" which may completely enclose the food. 403+, for a boiler or deep fat fryer which may include a lid, but in which the food is treated in "body of heated liquid".
