DEFINITION

Classification: 99/323.5

(under subclass 323.4) Device designed to pop corn or other cereal by heat treatment at substantially atmospheric pressure.

(1) Note. The atmospheric pressure in the definition of this subclass refers to the ambient conditions in and around the device and the individual kernel of popcorn. This is to be distinguished from that heat which penetrates into the interior of a kernel, heats at least some of the internal fluid to the point of vaporization, and thus contributes to the bursting of a kernel.
