ABSTRACT:
In an insulating jug (1) having a stopper (4) on which is arranged a sealing element (13) having a generally radially extending sealing lip (16) that in the closed position lies on a generally radially extedning sealing surface (19) on the housing (2) of the insulating jug (1) , a reliable seal is attained even when there are relatively large discrepancies in the relative dimensions of the sealing parts. This is achieved through the bending stress of the sealing lip (16) being greater than the force extended on the sealing lip (16) by the fluid in the container, and by arranging a free space (23) on the side of the sealing lip (16) facing away from the sealing surface (19).
