FIELD: transport, package.
SUBSTANCE: invention relates to cover (3) for sealing reservoir (1), which cover is provided with circumferential bead (2) on its top edge. He cover (3) is made of polymer film by deep drawing or die casting method and is provided with catching the thickening (2) of reservoir (1) directed essentially downwards edge flange (4), where this edge flange (4) is performed with at least small outward tilting and is provided with multiple inward projections (5), which can catch thickening (2) of reservoir (1) from below. The projections in section have "roofllike" shape. In this structure, the lower of two surfaces of "roof" is positioned more flat than upper surface of "roof" where in the cover there are several recessions with depth decreasing towards edge flange (4).
EFFECT: implementation of cover provides its manual installation onto reservoir with reliable sealing.
