A spill resistant lid includes a sealing bead in pressure contact with the inside wall of a container to be closed when the lid is in sealing position with respect to the container to substantially seal the container. The lid includes a first cylindrical wall and a second cylindrical wall spaced apart to form a receiving channel for the top of a container to be sealed. A ridge extends into the channel from the first cylindrical wall to hold the lid in place. The sealing bead extends into the channel from the second cylindrical wall. A central lid portion closes the area inside the second cylindrical wall and applies sealing pressure to the bead. In a preferred embodiment a third cylindrical wall in the central lid portion is joined to the second cylindrical wall by a web. The relative positions of the second cylindrical wall, the web, and the third cylindrical wall are deformed when the lid is in sealing position on the container and such deformation causes the bead to apply sealing pressure to the inside container wall. The central lid portion also preferably includes a container bottom platform and container receiving groove or secondary container platform for receiving and holding the bottom of a container stacked on the lid.

1. A spill resistant lid adapted to be removably and sealably attached to an open topped container having an outside wall and an inside wall with the inside wall forming an inside diameter of the container, comprising:a first cylindrical wall; a second cylindrical wall spaced inwardly from and connected to the first cylindrical wall to form a channel therebetween to receive the open top of said container; a ridge in the first cylindrical wall extending into the channel, said first cylindrical wall and ridge cooperating to allow the wall and ridge to move to enlarge the channel when the top of the container is inserted into the channel and the ridge to move inwardly toward the outside wall of the container when the lid is in sealing position over the top of the container; an inner bead extending from the second cylindrical wall into the channel, said bead having a normal outside diameter larger than the inside diameter of the open container at a location along the inside wall of the container contacted by the inner bead when the lid is in sealing position over the top of the open container; and a central lid portion secured to the second cylindrical wall and closing the area inside the second cylindrical wall, said central lid portion including a third cylindrical wall and a web joining the third cylindrical wall to the second cylindrical wall, wherein the third cylindrical wall is displaced downwardly when the lid is placed in sealing position over the open topped container and the web is displaced at a downward angle with respect to the second cylindrical wall whereby sealing force is applied by the inner bead against the inside wall of the container when the lid is placed in sealing position over the open topped container.
