A starting material for the containers is produced by mixing inorganic filler with a thermoformable polymer material in such a mixing ratio that the quantity of filler in the produced starting material is at least 40% of the total weight of the mixture. The starting material is extruded into a continuous web which is heated to a temperature suitable for thermoforming of the web, at least 190.degree. C., and is fed into a forming machine of conventional type for thermoforming of the web under vacuum at the above-mentioned temperature for forming web-like continuous, interiorly sterile, cup or beaker shaped containers. The containers are finally separated from one another by incisions in the web regions between the opening contours of each respective container.

The first part is provided with a front plane, a top plane, a bottom plane and two side planes. The second part is mountable on the first part to define a rear plane of the container. The front plane of the container forms an angle of less than 90.degree. with the bottom plane and an angle of greater than 90.degree. with the top plane.

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.
