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.

[ What is claimed is:] [1.] A container for delivery of flowable material, comprising:a deformable, one piece, unitary plastic body compressible in a longitudinal direction thereof, and having a first transverse diameter and a shoulder projection, said body defining an interior volume and having an axial length;a neck unitarily formed with said body at one axial end of said body, said neck having a second transverse diameter smaller than said first transverse diameter, said neck having a small projection through which flowable material is delivered;a cup-shaped, one piece bushing formed of a small unitary piece of plastic receiving said body and having a bushing floor and a passage opening in said floor receiving said neck, said floor engaging said shoulder projection of said body;a piston formed of a single, unitary piece of plastic, slidably mounted in said bushing and movable to positions in said bushing relative to said bushing floor; andindicators on said piston and said bushing indicating movement of said piston in said bushing, said indicators including cooperating checking means on said bushing and said piston for force-locking said bushing and said piston in relative positions along a path of movement of said piston;whereby, movement of said piston in said bushing toward said bushing floor reduces said volume of said body by reducing said axial length for regulating quantitative discharge of flowable material through said neck.
