A container with a material-dispensing portion is disclosed where the material-dispensing portion has an opening disposed in a predetermined plane and has an endless surface, said surface being inclined to said plane. The container is in combination with a sheet-like sealing element having a marginal portion bonded to the surface of the container around the opening and having a median portion overlying the opening, the median portion being inclined with reference to the plane of the opening and making therewith an angle which, at most, slightly exceeds the angle between the plane of the opening and the endless surface of the material dispensing portion.
