The transfer hose has an outlet end which can be removed from the passage so that it can be manipulated outside the passage and the fluid transferred through the passage via the outlet end. The transfer hose elastically pretensions the elastic spring element in this removal position and the elastic spring element is at least partially relaxed in a stowed position so that, via the elastic spring element, the transfer hose is pulled back from the removal position into the stowed position when the transfer hose, and thus the outlet end, is arranged within the passage. The transfer hose, in the stowed position, is arranged in the passage in a spiral, a helical, and/or a meandering manner via the elastic spring element. ## Claims ### Claim 1 A transfer port for transferring a fluid from a fluid reservoir to a removal area through a passage, the transfer port comprising: the passage which is arranged in a passage plane, the passage comprising a passage axis which is arranged substantially orthogonal to the passage plane; a transfer hose which is arranged within the passage, the transfer hose being configured to guide the fluid, the transfer hose comprising an outlet end which is configured to be pulled out of the passage from a stowed position within the passage to a removal position outside the passage so that the outlet end can be manipulated in the removal position outside the passage and the fluid can be transferred through the passage via the outlet end of the transfer hose; an elastic spring element which is directly mechanically connected to the transfer hose; and a port cover which is arranged pivotably on the passage and which is configured to close the passage, wherein, the transfer hose elastically pretensions the elastic spring element in the removal position and the elastic spring element is at least partially relaxed in the stowed position so that, via the elastic spring element, the transfer hose is pulled back from the removal position into the stowed position when the transfer hose and thus the outlet end is arranged within the passage, and the transfer hose, in the stowed position, is arranged in the passage in at least one of a spiral manner, a helical manner, and a meandering manner via the elastic spring element. ### Claim 2 (depends on 1) The transfer port as recited in claim 1, wherein the transfer hose, in the stowed position, is arranged in the passage in at least one of the spiral manner, the helical manner, and the meandering manner within the passage plane via the elastic spring element. ### Claim 3 (depends on 1) The transfer port as recited in claim 1, wherein, the elastic spring element is guided along the transfer hose and is mechanically connected to the transfer hose along a longitudinal extent of the transfer hose so that the elastic spring element is guided at least partially parallel to the transfer hose, and the elastic spring element is arranged in the passage. ### Claim 4 (depends on 3) The transfer port as recited in claim 3, wherein the elastic spring element is guided along the transfer hose and is mechanically connected to the transfer hose at one contact point or at several contact points along the longitudinal extent of the transfer hose so that the elastic spring element is guided completely parallel to the transfer hose, and the elastic spring element is arranged in at least one of a spiral manner, a helical manner, and a meandering manner in the passage. ### Claim 5 (depends on 4) The transfer port as recited in claim 4, wherein the elastic spring element is arranged in at least one of the spiral manner, the helical manner, and the meandering manner within the passage plane in the passage. ### Claim 6 (depends on 1) The transfer port as recited in claim 1, wherein the elastic spring element is a wire-shaped bending spring. ### Claim 7 (depends on 6) The transfer port as recited in claim 6, wherein the wire-shaped bending spring is formed from at least one of a spring steel and a stainless spring steel. ### Claim 8 (depends on 1) The transfer port as recited in claim 1, wherein, the transfer hose further comprises a connection piece at the outlet end, and the connection piece is configured to establish a connection of the transfer hose to a removal device within the removal area so that, when the connection piece is connected, the transfer of the fluid to the removal device is possible via the connection piece which is sealed off from an environment of the removal area. ### Claim 9 (depends on 1) The transfer port as recited in claim 1, wherein the port cover comprises a bayonet closure which is configured so that the port cover, when closed, can be transferred into at least one of a secured position and a sealed position via the bayonet closure. ### Claim 10 (depends on 1) The transfer port as recited in claim 1, further comprising: a holder which geometrically corresponds to at least one of the outlet end and to the connection piece, the holder being associated with the passage and being configured to accommodate the outlet end. ### Claim 11 (depends on 10) The transfer port as recited in claim 10, wherein the holder is configured to accommodate the connection piece so that a removal of the connection piece from the holder is possible when the port cover is open. ### Claim 12 (depends on 10) The transfer port as recited in claim 10, wherein, the holder is at least one of a clamp holder and a clip holder for the outlet end, and the at least one of the clamp holder and the clip holder is/are configured to enable a removal of the outlet end in a direction which is substantially parallel to the passage axis. ### Claim 13 (depends on 12) The transfer port as recited in claim 12, wherein, the holder is the at least one of the clamp holder and the clip holder for the connection piece at the outlet end, and the at least one of the clamp holder and the clip holder is/are further configured to enable a removal of at least one of the outlet end and the connection piece in the direction which is substantially parallel to the passage axis. ### Claim 14 (depends on 10) The transfer port as recited in claim 10, further comprising: a support device which is arranged in a direction of the fluid reservoir, the support device being configured to have the holder be accommodated thereon. ### Claim 15 (depends on 1) The transfer port as recited in claim 1, wherein the transfer port is a liquid transfer port. ### Claim 16 (depends on 1) A transfer system comprising: a fluid reservoir; a removal area; and the transfer port as recited in claim 1.
