Covering device for a container

A covering device for a container having an annular rim, comprising

• a holder configured for releasable securement onto the rim of the container,
• a lid pivotally mounted to the holder for pivotal movement about an axis, and
• wherein the holder comprises a clamping element and a counter support which are configured to receive the rim therebetween with the clamping element pressing the rim against the counter support, and with the clamping element comprising two clamping jaws which are moveable toward and away from the rim within a plane which is parallel to a plane defined by the rim,
• wherein the jaws are integrally interconnected and are spaced apart along a curved line which generally corresponds to the curvature of the annular rim, and wherein a coupling member is positioned between said jaws along said curved line,
• wherein the two clamping jaws are moveable between a clamping position wherein the jaws press the rim against the counter support, and an open position, and wherein the two clamping jaws are naturally biased to assume the clamping position,
• wherein said holder further comprises an actuation element for selectively moving the clamping jaws from the clamping position to the open position, with said actuation element comprises two radially directed levers, with each lever being connected to one clamping jaw such that movement of the levers toward each other causes the jaws to move toward the open position.
