Stacking device for mesh sterilizing trays

A sieve tray for holding medical products, the sieve tray comprising:

• a sieve tray bottom;
• sieve tray sidewalls arranged on the sieve tray bottom and extending upwards from the sieve tray bottom;
• at least one grip handle rotatably articulated to one of the sieve tray sidewalls of the sieve tray;
• and
• a sieve tray lid closing the sieve tray,
• the sieve tray defining a first indentation or recess surrounding the sieve tray bottom,
• the sieve tray bottom comprising a bottom projection,
• said bottom projection and first indentation or recess being configured for fixing the sieve tray and an identically configured sieve tray in a stacked state in which the sieve tray is fixed against lateral displacement relative to the identically configured sieve tray in a length direction and a width direction, with the bottom projection of the sieve tray fit within the sieve tray sidewalls of the identically configured sieve tray,
• the sieve tray lid comprising a circumferential rim that surrounds a second indentation or recess intermitted in a region of the grip handle,
• the second indentation or recess of the sieve tray lid configured to receive the bottom projection of the identically configured sieve tray, with the bottom projection of the identically configured sieve tray fit within the circumferential rim to fix the sieve tray to the identically configured sieve tray in the stacked state,
• wherein the sieve tray lid is recessed downwards in the region of the grip handle and forms a grip handle-receiving portion, so that in a folded position, the grip handle is flush with a surface of the sieve tray lid.
