A container made of flexible material having a depending container engaging sidewall and a raised top surface. The depending container engaging sidewall is formed with an inner flange having notches spaced around it length and a resilient outer flange with intermittent elongate bead means aligned with the notches of the inner flange and grooves in a shoulder interconnecting the flanges to engage a rolled top of a container. The intermittent bead means hold the lid firmly to the container and the notches and grooves permit steam accumulating in the container to be vented past ends of the bead means and to atmosphere as directed by the outer flange.
