1. A device for filling a receptacle with a liquid that is intended in particular for consumption, the device comprising: a balloon-type body that is liquid-tight relative to the liquid and is gas-tight;the balloon-type body insertable into an opening of the receptacle and securable on or in the opening of the receptacle after complete insertion;after complete insertion, the balloon-type body is fillable and inflatable with an expansion medium such that the balloon-type body contacts an inner wall surface of the receptacle in an inflated state of the balloon-type body;the balloon-type body, in an initial state of the balloon-type body prior to inflation, comprises folds that are folded in a circumferential direction of the balloon-type body, wherein the folds have fold pockets that extend in a longitudinal direction of the balloon-type body;wherein the balloon-type body comprises an outer wall surface with a profiling, wherein the profiling is configured such that, in the inflated state of the balloon-type body, a continuous passage is formed extending from a bottom of the receptacle up to the opening of the receptacle, wherein through the continuous passage, upon filling of the receptacle, air contained in the receptacle can flow out or, upon emptying of the receptacle, liquid contained in the receptacle can flow out;wherein the profiling comprises strip-shaped stays formed as one piece together with the balloon-type body, wherein the strip-shaped stays are projecting past a wall surface of the balloon-type body and wherein the strip-shaped stays extend from the bottom of the receptacle up to the opening of the receptacle;wherein the strip-shaped stays each extend in one of the fold pockets of the folds in the initial state of the balloon-type body prior to inflation. 2. The device according to claim 1, wherein the folds are folded in a wavy shape or a zigzag shape, viewed in a cross-section of the balloon-type body. 3. The device according to claim 1, wherein the folds, viewed in a cross-section of the balloon-type body, are embodied as lobes that are arranged so as to rest against an outer circumference of the balloon-type body. 4. The device according to claim 1, wherein the balloon-type body is comprised of an elastically expandable material and, upon inflation of the balloon-type body, the folds of the balloon-type body are initially unfolded and subsequently the elastically expandable material of the balloon-type body is expanded. 5. The device according to claim 1, wherein the balloon-type body is comprised of a non-expandable material and, upon inflation, the folds of the balloon-type body are unfolded. 6. The device according to claim 1, wherein the balloon-type body is comprised of a plastic material and of fibers embedded in the plastic material. 7. The device according to claim 6, wherein the fibers have an expansion capacity that is different from an expansion capacity of the plastic material. 8. The device according to claim 7, wherein the fibers are comprised of a material that is less expandable than the plastic material and the fibers extend substantially in an axial direction of the balloon-type body.
