Closing device for wide-mouth containers formed by locally deformable elastic polyethylene or similar plastic substance having similar properties characterized in that it comprises an integral peripheral rim protruding upwards having the inner and outer walls spaced in cross section and a connecting wall to define a groove adapted to receive the peripheral edge or mouth of the container having such outer wall a protruding portion adjacent to the lower edge and having internal side dimensions slightly smaller than the edge or mouth of the container and is constituted and arranged to be flexed outwardly when the edge portion of the container is forced over the mouth thereof thereby closing the interior sides of the outer and connecting walls keeping said inner wall normally taut the central wall and the latter being locally defocused. This can be adjusted by a downward pressure of the fingers to simultaneously facilitate a local distension upwards of the edge and to separate the outer wall thereof by contacting the fingers with an upward thrust of the projecting portion of said outer wall both when the coupling is completed end of the closure to impose a partial vacuum on the container so as to initially disengage the closure of the container.
