| 摘要 |
The present invention discloses a container to supply fluid material, having a yieldable, plastic container body, which can be compressed in its longitudinal direction, and a neck of less diameter attached to a body end having a projection. The supply through the neck projection corresponds to the volume reduction that is achieved by diminishing the body length in order to quantitatively regulate the material being supplied through the neck. A cup-shaped bushing has a floor in communication with a body flange projection. The bushing floor has a passageway opening for the neck. A piston can be slipped into the bushing until it has been put into contact with the bushing floor. An indicator arrangement establishes a visible indication of the piston movement path in the bushing.
