FIELD: package and storage.
SUBSTANCE: group of inventions is intended for sealing with maximum possible tightness of vessel (1) equipped with hole (2) while maintaining low consumption of material used for cover (3). For this purpose, tool (10) is proposed, which closes hole (2) of vessel (1) with lid (3). Tool (10) comprises plate (12) made with possibility of its introduction into hole (2) of vessel (1). Besides, the tool contains at least one roller (11) installed on plate (12) of the tool. Said at least one roller (11) is configured to deviate from the initial position radially outward, into the sealing position, and returning to its initial position, providing time-limited action of radial force on sealing edge (4) of cover (3). Bead (4) is located between said at least one roller (11) and inner side (5) of vessel.
EFFECT: using the group of inventions enables hermetically sealed vessel.
