Abstract: A fixture for recycling bottles made of plastics, which includes a base plate and means for anchoring the bottles arranged on the upper side of the base plate and engaging in indentations provided on the bottle bottoms, and a recycling bottle made of plastics to be used with such a fixture and including an indentation on its bottle bottom. In order to facilitate handling of the bottles for recycling purposes and to enable the automated determination of possible deposits for the bottles as well as the simple and rapid recyclability of the bottles, it is provided that the anchoring means, in a sense oriented away from the upper side of the base plate, have decreasing cross sections and barb-shaped formations. Thus, the optimum support of the bottles on the fixture is safeguarded. Preferably, the base plate is located within the projection of the bottles onto the base plate.
