Abstract: A substantially paper-based composite container for an off-gassing product includes a paperboard can body having a substantially gas-impervious liner attached to an inner surface thereof, and a pair of substantially paper-based end closures attached to the opposite ends of the can body, each end closure defining a generally cylindrical sealing panel in contact with an inner surface of the can body. Heat-sealable materials are disposed on opposing surfaces of the sealing panel and can body. The sealing panels of the end closures are attached to the can body by heat seals. The heat seal for at least one of the end closures is discontinuous such that at least one vent channel extends through the heat seal so as to establish fluid communication between an interior of the composite container and the environment outside the composite container. The at least one vent channel is operable to vent excess gas pressure from the interior of the container.

Abstract: The present invention relates to a method for providing a product viewing window in a container. The container has at least a body ply and a liner ply, wherein the body ply has at least one aperture therethrough. The liner ply is adhered across the aperture, forming a window into the container. A window-finishing machine that comprises at least two platens and, optionally, a machine pocket positioned between them, a heating element extending through at least one of the platens, and a pressurized air device engages a container. The heating element heats the window of the container to the desired temperature, pressurized air is injected into the container such that the window is forced at least partially through the aperture of the container (and optionally into contact with the machine pocket wall), and the container window is then cooled to the desired temperature.

Abstract: The present invention relates to a method for providing a product viewing window in a container. The container has at least a body ply and a liner ply, wherein the body ply has at least one aperture therethrough. The liner ply is adhered to the inner surface of the body ply and has a portion extending across the aperture, forming a window into the container. The method involves providing a window-finishing machine that comprises at least two platens and, optionally, a machine pocket positioned between them, a heating element extending through at least one of the platens, and a pressurized air device that is adapted to release pressurized air into the container through at least one of the platens. The container is engaged between the platens in an airtight manner and, optionally, the container window is positioned adjacent the inside wall of the machine pocket. The heating element heats the window of the container to the desired temperature, pressurized air is injected into the container such that the window is forced at least partially through the aperture of the container (and optionally into contact with the machine pocket wall), and the container window is then cooled to the desired temperature.
