DEFINITION

Classification: 141/331

(under subclass 311) Filling apparatus which comprises a funnel, i.e., a fluid supporting and guiding means, gravity discharged, which generally speaking has an inlet opening of greater extent than its outlet opening, with or without additional flow controlling means.

(1) Note. A funnel is intended to receive an unconfined flow, and its outlet is to be inserted within the receiver inlet. In the combinations herein claimed the funnel may be a first, second or third separable portion of a filling system, and may be claimed in any combination with a preceding supply or succeeding receiver or both, or as a subcombination.

(2) Note. So-called funnels with dispensing-type discharge assistants, e.g., movable traps, antibridging screw conveyors etc., have been placed in Class 222 in appropriate subclasses.
