Abstract
A plastic container having a storage chamber which graduates from a shoulder section into a bottle neck, in such a way that the length of the bottle neck can be changed about its axis. Thus, this invention provides a constriction between the shoulder section and a pour-out area. The constriction is adjacent the shoulder section and is followed by an area which can be axially compressed. The constriction can serve as a sealing area. Liquid, free-flowing and pourable media can be discharged in doses using a metering element which is fixed to the top of the bottle neck and which penetrates the constriction. By exerting pressure on the metering element, it is possible to establish an open or closed connection between the metering element and the storage chamber of the plastic container.
