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.

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.

The invention comprises a container comprising: a base; at least one paper-based sidewall seamed to and extending upwardly from the base, wherein the at least one sidewall comprises a score line near the base that is at least partially circumferential and is configured to be torn through to remove the base from the sidewall; and a liner ply adhered to an interior surface of the sidewall.

A can containing a solid, liquid and/or a gaseous medium which can have excess pressure or can develop such during transport or storage. The cylindrical can shell of the can includes paper or cardboard material and at least two wound layers, and is closed at the bottom with a bottom element and at the top with a cover element. The innermost layer of the can shell consisting of a straight-wound barrier layer, which includes a longitudinal seam that runs in the longitudinal direction of the can and is sealed inwards by a film layer, which overlaps the barrier layer near the longitudinal seam, or the longitudinal seam is sealed by a sealing strip running straight in the longitudinal direction or the longitudinal seam forms an increase in thickness and the longitudinal edge of a further layer faces a flank of the increase in thickness.
