Abstract

A metering device is used for the metered administration of a flowable preparation together with a flowable carrier medium. A storage container for the preparation has at least one access opening. A metering plunger body can be moved in a sealed manner in the storage container between a starting position and at least one metering position. The metering plunger body is hollow. A metering sleeve has on a bottom side an eccentric metering sleeve opening. An inner plunger body has on the bottom side an eccentrically arranged plunger body opening. In a through relative rotation position of the metering sleeve relative to the inner plunger body a passage is provided between the inside of the storage container and the inside of the inner plunger body. In a closed relative rotational position this passage is closed. This results in a user-friendly and compact metering device.
