1. A collapsible container in the form of a collapsible and re-extendable drinking cup, comprising:
a cup-shaped element made of flexible, deformable material having a bottom-side base part, a top part having an opening and side wall sections arranged therebetween, and a lid;
wherein the side wall sections are foldable toward each other along fold lines formed into the material of the cup-shaped element;
wherein the cup-shaped element is collapsible by twisting the base part to the top part;
wherein the fold lines are oriented so that the cup-shaped element constricts between the base part and the top part from torsion when twisting the base part;
wherein in the unfolded state of the cup-shaped element, first fold lines are arranged running from the base part diagonally upward to the top-side opening;
wherein in the unfolded state of the cup-shaped element, second fold lines are arranged running from the base part at a smaller angle to the perpendicular than the first fold lines or substantially perpendicular upward to the top-side opening;
wherein the side wall sections adjacent to the first fold lines and to the second fold lines are configured to swivel opposite to each other,
wherein in the fully unfolded state, the side wall sections adjacent to the first fold lines are oriented inward toward the first fold line, and the side wall sections adjacent to the second fold lines are oriented outward toward the second fold line, wherein an upper region of the cup-shaped element is enclosed by a sleeve and the sleeve is pushed from the underside of the cup-shaped element on to the cup-shaped element.
