1. A thermoforming device (10), having a molding tool (11), comprising an upper part (12) and a deep-drawing mold (13) underneath the upper part (12), for molding at least one cup (1) into a heated sheet of film (2), the deep-drawing mold (13) forming a side wall (4) and a bottom region (5) on the at least one cup (1), molding of the cup (1) into the deep-drawing mold (13) taking place by producing a positive pressure on the sheet of film (2) in a direction of the deep-drawing mold (13), the deep-drawing mold (13) comprising at least one first part-element (15), with a through-opening (17) for molding the side wall (4), and a second part-element (30), formed as a component that is separate from the at least one first part-element (15), for molding the bottom region (5), the first and second part-elements (15, 30) being movable in relation to one another in such a way that the second part-element (30) can in certain regions be introduced into an end face of the through-opening (17) of the first part-element (15) that is facing the second part-element (30), and a base area (35) of the second part-element (30) that forms the bottom region (5) of the cup (1) being adapted to a cross section of the through-opening (17) in the first part-element (15) in such a way that, to form different container heights, the base area (35) is configured be positioned to different heights (36, 37) of the through-opening (17) in such a way that the base area (35) of the second part-element (30) is arranged circumferentially at a small distance from a circumferential wall (34) of the through-opening (17) of the first part-element (15), characterized in that the deep-drawing mold (13) comprises at least two first part-elements (15) and the second part-element (30), and in that the at least two first part-elements (15) are configured to be adjusted into a position in which the at least two first part-elements are arranged out of alignment outside the upper part (12) and the second part-element (30), the second part-element (30) always being fixed in congruence with the upper part (12).
