Abstract
The device comprises a sheath in a synthetic material and including at least one protruding abutment for a latching on a neck of a container and a fitting collar for a portion of this neck. The sheath has a top provided with a sealing foil and is fitted inside a lid including fixation means associated with retainer members for the sheath. A space is defined between the sheath and the lid for accommodating a resilient deformation of the protruding abutment.
