FIELD: vessels sealing.
SUBSTANCE: invention is intended for vessels sealing. A tool is proposed for sealing an opening of a vessel having an inner side of a vessel by means of a lid, the tool comprising a tool plate configured to be inserted into the vessel opening to be sealed, at least one cylindrical roller installed in its initial position on the tool plate and having a smooth side surface. Wherein the specified at least one roller is made with the possibility of deflection with a radial component to the sealing position, as a result of which to the sealing edge of the lid located between the specified at least one cylindrical roller and the inner side of the vessel, and thus to the adhesive layer or the connecting layer, a certain force is applied to ensure sufficient tightness.
EFFECT: invention provides high efficiency in use.
