Docking and undocking of liquid carrying lines to and from a docking body

A line end for docking a liquid carrying line to a docking interface of a docking body having a second form that is conically tapered in the direction of flow, said line end comprising:

• a first form that is conically tapered in the direction of flow, which is adapted to the second conically tapered form in such a way that, in the docked state, the first form is situated in concentric opposition to the second form, set apart by an interspace defined therebetween by a sealing ring setting the first and second forms apart from one another,
• at least one cleaning element equipped on the periphery of the first conically tapered form and extending from the first conically tapered form toward the second conically tapered form;
• wherein the interspace is present substantially along the entire length of the coupling region;
• and
• wherein the at least one cleaning element is configured to capture the liquid that accumulates in the interspace.

A method for preventing liquid from being able to continue to flow when a line end of a liquid stream carrying line is undocked from a docking interface of a docking body, the line end being for docking a liquid carrying line to a docking interface of a docking body having a second form that is conically tapered in the direction of flow, said line end comprising:

• a first form that is conically tapered in the direction of flow, which is adapted to the second conically tapered form in such a way that, in the docked state, the first form is situated in concentric opposition to the second form, set apart by an interspace defined therebetween by a sealing ring setting the first and second forms apart from one another, and
• wherein the first conically tapered form is equipped on its periphery with at least one cleaning element, which extends from the first conically tapered form toward the second conically tapered form in order to capture liquid that may accumulate in the interspace,
• wherein the method comprises:
• applying a temperature flow to a coupling region between the docking interface and the line end, causing the liquid in the docking interface and in the line end to harden at least temporarily.
