Abstract: A cap and a corresponding method of manufacturing the cap for closing a container are described. The cap comprises a spirally wound sleeve comprising a first opening an a second opening, wherein the first opening and the second opening are opposed. Further, the cap comprises a head disk, wherein the head disk is arranged to close the first opening of the sleeve. The sleeve is made of paper. The second opening of the sleeve has a reinforcing element, and the reinforcing element is a structure extending into the interior of the sleeve.

Abstract: The invention relates to a method and a device for producing three-dimensional molded parts from a continuous sheet of a flat, plastically malleable fiber material via deep drawing with a stamp and an associated die, wherein the fiber material between the stamp and the die can be reshaped via a relative movement. The object of the instant invention is to offer a method and a device for producing three-dimensional molded parts in which the reshaping is done via deep drawing from a cut-to-size section in the continuous sheet and which leads to a high reshaping ratio. The problem is solved by connecting the round, rectangular, oval or irregular cut-to-size section for the molded part during the deep-drawing process to the continuous sheet of fiber material via at least one web and otherwise separating it from the continuous sheet via at least one stress-easing cut; a reshaping ratio, as the ratio of the diameter and the depth, of greater than 0.2 can be realized.
