1. A sieve basket for receiving medical items to be disinfected or sterilized, the sieve basket comprising a bottom having a plurality of apertures and a base plane bounded by side walls,
the bottom being a sheet metal part comprising periodic corrugations or indentations/bulges projecting from the base plane towards a sieve basket interior and/or towards a sieve basket exterior so that the bottom is given a meshwork surface structure, wherein
the bottom is constructed from a plurality of longitudinal struts running in parallel in the base plane and a plurality of transverse struts running in parallel in the base plane,
the plurality of longitudinal struts and the plurality of transverse struts running perpendicular to each other in the base plane, and
the plurality of longitudinal struts and the plurality of transverse struts undulate up and down in a wave form over the entire bottom with an exception of a transition section in an area of the side walls, in order to form the periodic corrugations or indentations/bulges, and wherein
the apertures, viewed in the base plane, have a rectangular shape and, by means of the corrugations or indentations/bulges, form a three-dimensional roof shape of two triangles towards the sieve basket interior and/or the sieve basket exterior.
