Sterile container and lid for a sterile container

A sterile container comprising:

• a receptacle having a bottom and side walls that define a holding space for surgical instruments or material to be held in a sterile state, and
• a generally polygonal lid for closing a complementary shaped opening of said receptacle, said lid comprising:
• a cover plate adapted to cover said holding space in a closure position;
• and
• mounting aids for mounting the lid on said receptacle, the mounting aids comprising:
• a plurality of mounting aid elements extending from respective corners of said cover plate which, in the closure position, each overlap at least partly at least one of said receptacle side walls,
• a plurality of positioning elements for guiding top edges of the receptacle side walls into a peripheral groove of the lid without becoming caught regardless of where the lid is initially placed on said top edges when commencing closure of the container, said groove being open in the direction of the holding space and defined by an inner groove side wall adapted to reside inside said holding space in said closure position and an outer groove side wall adapted to reside outside said holding space in said closure position,
• a peripheral projection spaced inwardly from said inner groove sidewall to provide a channel between said inner groove side wall and said peripheral projection, and
• at least one web connecting a portion of said peripheral projection at one side of said lid to a portion of said peripheral projection at an opposite side of said lid,
• each of said positioning elements spanning said channel and comprising a surface starting from said peripheral projection and ending at a distal end of said inner groove side wall for providing said guiding.
