(under the class definition) Subject matter including an outlet pipe extending internally from the container.
(1) Note. A dispenser adapted to operate by suction is placed here when only the container and internal outlet pipe are claimed, even though the arrangement is such that suction is necessary to cause dispensing. Certain types of canteens and those containers for use with spray guns having the internally extending outlet pipe as part of the container assembly are included in this subclass.
