The container has a bottom and an upward extending sidewall that terminates in a rim. The lid includes a central portion, and an annular gasket positioned to surround a perimeter of the central portion. The annular gasket includes an upper portion coupling the gasket to the central portion; a vertical portion descending downward from the upper portion; and a flexible skirt extending horizontally outward from an outer side of the vertical portion. The lid further includes an annular lid rim positioned to surround a perimeter of the upper portion of the gasket.
