A packaging method for packaging injection-molded plastic parts in final package units, the injection-molded plastic parts being pipette tips or medical reaction vessels and each having a longitudinal center axis (L A), which preferably extends centrally through an opening, the method comprising the steps of: - simultaneously removing multiple shots of K injection-molded plastic parts from K respective cavities, the K cavities preferably being distributed, in particular evenly, over C clusters, - evenly distributing the K injection-molded plastic parts in a cavity-pure manner over U cavity-pure subgroups in a first storing plane, preferably until each subgroup contains L injection-molded plastic parts, the number L of the injection-molded plastic parts of one subgroup corresponding to the maximum number A of injection-molded plastic parts that can be contained in one final package unit or to an integer divisor of A, - filling up the final package units in a cavity-pure or cavity-sorted manner until the final package units each contain A injection-molded plastic parts, characterized in that the injection-molded plastic parts of the subgroups are subjected to an optical lateral inspection, in particular for shape and/or surface defects, in a lateral inspection device, which comprises at least one digital camera, preferably multiple digital cameras spaced apart in a circumferential direction, before the final packages are filled up, and for this purpose, the subgroups are each divided into S sub-subgroups of injection-molded plastic parts disposed one behind the other, in particular linearly, and the S sub-subgroups are transported through the lateral inspection device one after the other by means of transfer means and are subjected to the lateral inspection there, and the S sub-subgroups are arranged in inspected cavity-pure subgroups in a second storing plane after having passed through the lateral inspection device, their composition preferably corresponding to the composition of the subgroups of the first storing plane in the event that no individual injection-molded plastic parts have been sorted out because of defects detected, and the second storing plane being formed either directly by the final package units or by a stationary or adjustable, preferably horizontal, intermediate storage, and the inspected subgroups being moved from the intermediate storage into the final package units. - simultaneously removing multiple shots of K injection-molded plastic parts from K respective cavities, the K cavities preferably being distributed, in particular evenly, over C clusters, - evenly distributing the K injection-molded plastic parts in a cavity-pure manner over U cavity-pure subgroups in a first storing plane, preferably until each subgroup contains L injection-molded plastic parts, the number L of the injection-molded plastic parts of one subgroup corresponding to the maximum number A of injection-molded plastic parts that can be contained in one final package unit or to an integer divisor of A, - filling up the final package units in a cavity-pure or cavity-sorted manner until the final package units each contain A injection-molded plastic parts, the injection-molded plastic parts of the subgroups are subjected to an optical lateral inspection, in particular for shape and/or surface defects, in a lateral inspection device, which comprises at least one digital camera, preferably multiple digital cameras spaced apart in a circumferential direction, before the final packages are filled up, and for this purpose, the subgroups are each divided into S sub-subgroups of injection-molded plastic parts disposed one behind the other, in particular linearly, and the S sub-subgroups are transported through the lateral inspection device one after the other by means of transfer means and are subjected to the lateral inspection there, and the S sub-subgroups are arranged in inspected cavity-pure subgroups in a second storing plane after having passed through the lateral inspection device, their composition preferably corresponding to the composition of the subgroups of the first storing plane in the event that no individual injection-molded plastic parts have been sorted out because of defects detected, and the second storing plane being formed either directly by the final package units or by a stationary or adjustable, preferably horizontal, intermediate storage, and the inspected subgroups being moved from the intermediate storage into the final package units.
