ABSTRACT:
A lid with a sealing device for containers includes a horizontal top (2; 50; 62), at least one air tube (6;51;63;73;83) attached to the lid (1;50;60;71;81), one or more suction cups (8;55;67;75;74;85;84) attached to the air tube and a hole (9;53;77;87) made in the lid and communicating with each air tube. Each suction cup accomplishes its sealing action between the lid and the container on which the lid is applied when the air tube to which each suction cup is attached is expanded by a compressed fluid, thereby causing the suction cups to adhere against the edge of the container and/or the lid applied on the container itself.
