Portion feed device for packaging

Abstract

A portion feed device ( 2 ) for a packaging ( 1 ) features a chamber ( 4 ) to accommodate a pourable solid product and a dispensing facility ( 2 ) neighboring onto this chamber. When in use, the inner tube ( 10 ) lies essentially horizontal and features inlet openings ( 51 ) on the dispensing side. By rotating the inner tube ( 10 ) around its main axis the inlet openings ( 51, 61 ) on the feed side can, either in sequence one after another or simultaneously, be brought into at least partial alignment or congruent agreement with the inlet opening or openings ( 13, 16 ) on the chamber side and/or the outlet opening or openings ( 14, 24 ). As a result of this rotation, when in the open setting, these inlet openings ( 51; 13, 16 ) form at least partially a passage between the chamber ( 4 ) and the dispensing facility ( 2 ) and, in a closed setting no passage is provided between the chamber ( 4 ) and the dispensing facility ( 2 ).
