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.

A METHOD TO PRODUCE PLASTIC TUBE THAT HAS AT LEAST ONE STIFFENER
20180117827 · 2018-05-03 · ·

A plastic tube has an inner tube, a stiffener layer, and an outer tube. The inner tube is arranged the support organ. A corrugated stiffener preform is formed with corner area walls shaped thinner than the other walls. The preform is fed upon the inner tube to form a stiffener layer that advances with a certain pitch upon the inner tube. The corner parts of every stiffener yield and the brush angle () between the lamellas of the outside gets greater than the corresponding brush angle between the lamellas of the inner side. The stiffener is joined to the inner tube with a melted plastic layer and fed upon the stiffener plastic tape joined to the stiffener with a melted plastic layer. Between the settled edges of the plastic tape a spiral weld joint is formed so that the plastic tape forms the outer tube.
