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.

The invention shows a filling transfer apparatus for bone cement with a cylindrical, upwardly open mixing container ( ) and a filling transfer piston ( ) which can be inserted therein, which is removably connected to the sleeve ( ) of a cement injector ( ) and which has an opening ( ) through which the mixed bone cement ( ) can be transferred into the sleeve ( ) through a pressing down of the filling transfer piston ( ). In this an ejection piston ( ) is inserted in the sleeve ( ) and has an aperture ( ) in the region of the opening ( ) for the through-flowing cement which can be closed by a plug ( ) after the removal of the cement injector ( ).

A single-piece plastic lid, having a lower part and a cap. The cap is connected to the lower part via a hinge. The lid has a guarantee strip to ensure that the lid cannot be opened unnoticed and that the lid cannot be removed from the container without damaging the guarantee strip. Thus, the guarantee strip has additional elements which enable a positive fit with both the lower part and the neck of the container. Corresponding positive fit elements are also provided on the container neck, for example in the form of snap-in elements.
