  • Patent number: 12116162
    Abstract: A can to contain a liquid and/or a gas is closed with a bottom element and a cover element. The innermost layer is a straight-wound barrier layer having a folded seam extending in a longitudinal direction. The barrier layer includes an inner diffusion-tight layer and an outer kraft paper layer. At least two further straight-wound layers made of paper or cardboard are around the barrier layer of the can shell. Adjoining cardboard or paper surfaces of the barrier layer and a next wound layer are adhered directly to each other. Each of the two further wound layers is longitudinally wound and include in the longitudinal direction an overlapping region with itself. The overlapping region of the next wound layer adjoining the barrier layer is offset relative to the folded seam of the barrier layer and the overlapping regions of the two further wound layers are located at different peripheral regions.

  • CAN
    Publication number: 20240217693
    Abstract: 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.
