Abstract

302,877. Weickel, P. July 9, 1928. Drop-delivering apparatus.-In a drop-delivery device comprising a pipette a connected to a bottle stopper b so as to be carried by the stopper within the bottle, the stopper is formed with an air vent c which communicates with the pipette and opens at the side of the stopper so as to be closed when the stopper is placed in the bottle neck. The stopper is made of rubber and the pipette is formed with a beaded' neck h adapted to be inserted in the duct forming the air vent, compression of the pipette by the bottle neck being avoided by forming the part of the stopper which holds it of reduced diameter.
