Abstract

A plastic container for apportionable delivery of flowable, especially pasty materials, has a discharge opening at one end and a self-contained chamber only open to the inside of the container at the other end. The chamber volume is reducible by manual deformation. The chamber is configured in one piece with the container body. The container body is configured as a cylinder. The inside space of the container body receiving the flowable material is separated from the inner volume of the chamber by a separator piston longitudinally slidable in the container body.
