The invention relates to containers and systems of containers, for example, trays, that can be arranged at angles of 0 or 180° so that different height positions can be obtained; that include a glider (8) to allow trays to move freely across one another under rapid use by a handler; and locking (5,6), securing (20,21) and support (23) mechanisms to ensure that the upper trays do not become disengaged during sudden movements, and to allow the trays to be stacked or nested, as appropriate for achieving different heights. |
