Collapsible container in the form of a collapsible and re-expandable drinking cup, comprising a cup-like element composed of flexible deformable material with a bottom-side base part, with a top part with an opening, and with side-wall portions (5a, 5b, 5c, 5d) arranged therebetween, wherein the side-wall portions (5a, 5b, 5c, 5d) are foldable in relation to one another along fold lines (7, 8) formed in the material of the cup-like element, wherein the cup-like element is collapsible by way of rotation of the base part in relation to the top part, wherein the fold lines (7, 8) are oriented in such a manner that the cup-like element constricts between the base part and the top part during the rotation of the base part as a result of twisting, wherein, in the expanded state of the cup-like element, first fold lines are arranged so as to extend from the base part upwards towards the top-side opening in an oblique manner, wherein, in the expanded state of the cup-like element, second fold lines are arranged so as to extend from the base part upwards towards the top-side opening at a smaller angle to the vertical than the first fold lines or in a substantially vertical manner, wherein the side-wall portions (5b, 5c and 5a, 5b, respectively) in each case adjacent to the first and second fold lines (7, 8) are pivotable oppositely in relation to one another, characterized in that, in the completely expanded state, the side-wall portions (5b, 5c) in each case adjacent to the first fold lines are oriented inwards towards the first fold line, and the side-wall portions (5a, 5b) in each case adjacent to the second fold lines are oriented outwards towards the second fold line. a cup-like element composed of flexible deformable material with a bottom-side base part, with a top part with an opening, and with side-wall portions (5a, 5b, 5c, 5d) arranged therebetween, wherein the side-wall portions (5a, 5b, 5c, 5d) are foldable in relation to one another along fold lines (7, 8) formed in the material of the cup-like element, wherein the cup-like element is collapsible by way of rotation of the base part in relation to the top part, wherein the fold lines (7, 8) are oriented in such a manner that the cup-like element constricts between the base part and the top part during the rotation of the base part as a result of twisting, wherein, in the expanded state of the cup-like element, first fold lines are arranged so as to extend from the base part upwards towards the top-side opening in an oblique manner, wherein, in the expanded state of the cup-like element, second fold lines are arranged so as to extend from the base part upwards towards the top-side opening at a smaller angle to the vertical than the first fold lines or in a substantially vertical manner, wherein the side-wall portions (5b, 5c and 5a, 5b, respectively) in each case adjacent to the first and second fold lines (7, 8) are pivotable oppositely in relation to one another, characterized in that, in the completely expanded state, the side-wall portions (5b, 5c) in each case adjacent to the first fold lines are oriented inwards towards the first fold line, and the side-wall portions (5a, 5b) in each case adjacent to the second fold lines are oriented outwards towards the second fold line.
