Cover for a waste container

A cover for a waste container comprising:

• a cover plate with a peripheral rim which fits onto a standing upper rim of said waste container;
• said cover plate includinq a recessed circular opening, having an inner periphery, which is closable;
• a circular lid to close said cover plate opening including an outer peripheral wall which fits inside said inner periphery of said cover plate opening;
• co-acting cams located on said inner periphery of said cover plate opening and said outer peripheral wall of said lid for locking said circular lid in said cover plate opening;
• and wherein said co-acting cams located on said inner periphery of said cover plate opening are elongated and are disposed sloping relative to the line of symmetry of said circular lid and wherein at least one cam receiving opening is formed on the inner periphery of said cover plate opening between an end of one said co-acting cam and an other end of an adjacent one of said co-acting cams, wherein each said cam receiving opening serves for passage of one of said co-acting cams located on said outer peripheral wall of said lid, and wherein an axially oriented lower surface of at least one of said co-acting cams which are located on said inner periphery of said cover plate opening and an opposite axial surface of said co-acting cams which are located on said outer peripheral wall each have a plurality of indentations that define different closing positions of said circular lid in said cover plate.

A cover for a waste container comprising:

• a cover plate with a peripheral rim which fits onto a standing upper rim of said waste container;
• said cover plate including a recessed circular opening, having an inner periphery, which is closable;
• a circular lid to close said recessed circular opening of said cover plate, said lid including an outer peripheral wall which fits inside said inner periphery of said cover plate opening;
• and
• co-acting cams located on said inner periphery of said cover plate opening and said outer peripheral wall of said lid for locking said circular lid in a plurality of different closing positions, wherein in a first of said different closing positions said collecting cams cooperate to releasably secure said circular lid onto said cover plate, and in at least a second of said different closing positions said co-acting cams cooperate to permanently attach said circular lid to said cover plate,
• said co-acting cams located on said outer peripheral wall of said lid are resilient hooks which flex independent of said outer peripheral wall of said lid in a direction away from said co-acting cams located on said inner periphery of said cover plate in order to engage said co-acting cams of said inner periphery of said cover plate, and
• said co-acting cams located on said inner periphery of said cover plate are positioned on different levels from each other in order to define said different closing positions as said hooks engage said co-acting cams located on said inner periphery of said cover plate.
