A plastic pressure container has an essentially cylindrical container body with an opening closable in a pressure-tight manner by a valve attachment for dispensing a filling product. An interior plunger is arranged in a longitudinally displaceable manner along a longitudinal axis to subdivide the container body into a receiving chamber adjacent to the opening for the filling product and into a separated reservoir in a pressure tight manner, for a pressure medium. The plunger includes two circumferential sealing lips separated in the axial direction. An upper sealing lip extends into the receiving chamber and a lower sealing lip extends into the reservoir, and these are pressed in a fluid-tight manner onto an inner wall which delimits the interior of the container body, by pressure in the receiving chamber and reservoir.

A spray attachment for bringing out fluid substances in the manner of a jet includes a cap with an annularly peripheral, closed skirt with a wall, on whose inner side or outer side first fastener is integrally formed. The first fastener can engage a corresponding second fastener of an outer wall or inner wall of a container neck. The skirt at a longitudinal end is closed off by a cover surface having a recess. A receiving part for receiving an insert part is arranged in the region of the recess, and includes a conical receiving surface for receiving a conical peripheral surface of the insert part. The conical receiving service and the conical peripheral surface delimit at least one through-channel for fluid substance, through which the fluid substance can be brought out.

An injection-molded preform is disclosed for production of a plastic container by a blow-molding method with an elongated, tube-like body, which is closed on its one longitudinal end and has a neck section that is provided with a pour opening on its other longitudinal end, which neck section includes an injection molded connection to an injection molded closure part, wherein the closure part includes: a flip-top closure and an annular section with an inner wall, which inner wall rests directly on an outer surface of the neck section and completely encloses an annular area of the outer surface of the neck section.
