Conveying storage device and corresponding method

A conveying storage device for containers, comprising:

• a first conveyor which is drivable in a first direction;
• a second conveyor which is drivable in a second direction, wherein the first direction and the second direction are opposite to each other, wherein the first conveyor and the second conveyor are arranged parallel to each other such that the containers are transferable from a first conveying surface of the first conveyor to a second conveying surface of the second conveyor;
• a transfer device for transferring the containers from the first conveying surface to the second conveying surface;
• an additional element;
• and
• a separating element;
• wherein a passage region exists along a transition region between the first conveying surface and the second conveying surface between the transfer device and the separating element, wherein the transfer device is movable into an emptying position during an emptying process of the conveying storage device, wherein the additional element is relatively movable in relation to the transfer device during the emptying process, and wherein the additional element is introducible into the passage region or arranged in the passage region during the emptying process and is adapted to transfer containers to the second conveyor.
