Abstract

A container for delivery of flowable material has a plastic, deformable container body which can be compressed in its longitudinal direction and a neck of smaller diameter attached to one body end with formation of a projection. The delivery through the neck projection corresponds to the volume diminution obtained by the length reduction of the body, for quantitative regulation of the material delivered through the neck. A cup-shaped bushing has its floor engaged on a shoulder projection of the body. The bushing floor has a passage opening for the neck. A piston is slidable in the bushing until it contacts the bushing floor. An indicator arrangement makes a visible indication of the movement path of the piston in the bushing.
