Abstract: A method of producing a gaseous, hydrogen peroxide-containing sterilization fluid displaying good, uniform sterilization properties is disclosed. The method includes vaporizing liquefied hydrogen peroxide by injecting the liquefied hydrogen peroxide intermittently in finely-divided form into an air current which serves as a vaporization agent, wherein the air current is kept at a constant or insignificantly varying elevated vaporization temperature. An even vaporization temperature of the air current is ensured because the air, prior to vaporization, is heated by heat exchange with a heating element having a large mass or thermal capacity and a large heat exchange surface area which is kept at the desired elevated temperature by regulated energy supplied to the heating element. During breaks in vaporization between the intermittent injection of the liquefied hydrogen peroxide, the heat exchange surface area is heated with the aid of heat stored in the heating element.

Abstract: A packaging container is manufactured through fold forming, vacuum forming, injection molding or other processing to shape a plastically deformable, flexible material, comprising a tubular container body with two longitudinal edges which delimit between them a mainly flat container wall. In order to prevent deformation and/or cracking of the packaging container with normal handling of the side walls, the packaging container is provided with reinforcing elements formed through plastic deformation of the wall material in the region of the longitudinal edges. The reinforcing elements strengthen and stiffen the container and enable it to be conveniently gripped with the hand without the risk of the edges and/or the adjacent side walls being cracked or deformed.
