Abstract: A packaging unit for accommodating glass rolled onto a winding core is provided. The packaging unit includes at least two wall parts that can be separated from one another and together form a closed unit. A first retaining element is connected to a first wall part and a second retaining element is connected to a second wall part arranged opposite the first wall part. A damping element is connected to at least one retaining element and/or to at least one of the first and second wall parts.

Abstract: A container for wafer like objects includes a container body and a door closing the container body and which is provided with a device for locking and unlocking the door, including locking elements and holding elements in which the locking elements that lock the door engage. At least one locking element includes a first signal element which is operatively connected to a second signal element arranged at a position important for the engagement of the locking element in the holding element.

Abstract: A transportation system (100/200) has a wafer container (100), such as a FOUP, to rest on a support surface (200). The container has kinematic coupling grooves, and the support surface has kinematic coupling pins. Grooves and pins are at least partially electrically conductive and allow coupling an electric device (150) associated with the container to an electrical circuit (250) associated with the support surface. Device and circuit in combination allow to perform a variety of functions, such as monitoring the correct position of the container, and exchanging signals.
