Container lid and associated assembly

A lid and container assembly includes a container having a rim portion that defines a container opening, and a lid having (i) a cover portion positioned over the container opening, and (ii) a skirt extending from the cover portion and positioned circumferentially around the rim portion. The skirt defines an interior facing surface and an exterior facing surface. The skirt includes a sealing band extending from the interior facing surface positioned in contact with the rim portion. The sealing band defines a vertex along the extent of the sealing band. The vertex possesses (i) a first height at a first circumferential position of the sealing band, and (ii) a second height at a second circumferential position of the sealing band. The second height is greater than the first height. Height of the vertex asymptotically increases as the sealing band extends from the first circumferential position to the second circumferential position.
