Plastic container and corresponding metering element with a closure

摘要

Plastic container and associated dosing element comprising a constriction in the container neck which is either closed or open dependent on the position of the axially slidable dosing element, is new. The container neck between the outlet section (16) and the shoulder section (11) is provided with a constriction (121) which is constituted as a sealing section (14) adjoining an axially compressible section (15). The associated dosing element has a cylindrical bottom section which is axially slidable within the constriction (121) of the container neck so that passage from the storage space into the container neck is either closed or open.
