Tools and process for the production of a container

A method for producing a container using a tool, wherein in a thermoforming process, in particular a plastic deep drawing process

• a molding blank made from a thermoplastic is heated,
• the molding blank is being remolded by means of the positive mold, wherein a container bottom is formed from the molding blank at the bottom section of the positive mold, a circumferential, lateral wall is being integrally formed with the container bottom from the same material at a lateral wall section, and a stacking edge formed as a hollow profile, circumferentially protruding beyond an external contour of the lateral wall of the container around an entire external container face is being formed at a wall arranged at the lateral wall section, wherein the stacking edge is inwardly formed as an open notch toward an inner container side and arranged at a distance from the bottom,
• during remolding of the molding blank into the container, the wall is being arranged in a molding position circumferentially protruding around an entire external face of the positive mold in such a way that an angle smaller than 90° is formed between a wall side directed toward the bottom section and a portion of the associated lateral wall section extending from this wall side toward the bottom section, and
• after molding the molding blank, the wall is being moved into a demolding position, in which a distance of an end of the wall protruding in the molding position to the lateral wall section is reduced.
