Abstract
Abstract The flange-like lid rim of a packaging container, including the outwardly projecting gripping part shaped thereon, is laterally enclosed by an all-round rim portion, so that it is not accessible for opening the packaging container. The actuation of the gripping part leads to the separation of a rim extension of the container body engaging below the gripping part and to which the latter is non-detachably connected by a pushbutton connection. The sealing fixing of the lid to the container body takes place by interlocking engagement beads. The packaging container avoids any hot sealing joint as a guarantee seal and is made from completely burnable plastic.
