Abstract: A closure for sealing an opening of a tubular container is disclosed, the closure having a paperboard central panel with a plurality of secondary panels extending angularly therefrom forming a surface around the perimeter of the central panel. A plastic skirt is adhered around the perimeter of the central panel and to one side of the secondary panels opposite the surface to reinforce it. A metal foil layer is adhered to the surface, the foil having a side facing the sidewall of the container with a heat-activated adhesive layer thereon. The closure is positioned on the container with the central panel in registration with the opening and the heat-activated adhesive layer engaging the sidewall of the container. The seal between the closure and the container is effected by subjecting the container to an electromagnetic induction field, whereby eddy currents induced in the metal foil by the field cause the heat-activated adhesive to form a bond between the container sidewall and the secondary panels.

Abstract: A container adapted to be sealed with a lid is disclosed. The container cup has a lip with a raised sealing bead along its length. During sealing, the raised sealing bead compresses, thereby stretching the adhesive layer on the lower portion of the lid out of the way and forming a direct welded seal with the heat-resistant layer of the lid. The adhesive to either side of the sealing bead forms an adhesive seal between the lid and the remaining portion of the lip. This type of double seal is particularly effective in forming a durable, consistent seal when product is present on the lip of the container. The welded seal is also well suited to situations when the cup may be warped or the sealing bead is otherwise caused to be higher along some portion of its length than along other portions.

The projection either extends outwardly from the perimeter such that the projection is non-symmetrically disposed with respect to the imaginary line of any adjacent corner portion, or the projection extends non-continuously from an adjacent corner portion and is substantially symmetrically disposed with respect to the imaginary line of the adjacent corner portion. Containers are also provided with a lip having a substantially triangular-shaped horizontal cross-section.
