  • Patent number: 5279413
    Abstract: The container for flat articles, especially coins, which is part of a storage system for magnetic tape cassettes, in a motor vehicle, comprises a housing open on one side, a slider member insertable in the open side of the housing against a spring force and a locking device for locking the slider member in an inserted position. To provide a particularly reliable way of holding coins of different sizes so that they do not rattle when the container is moved, the slider member has a movable compartment floor which, as the slider member is pushed into the housing, is pressed by spring elements underlying it against an upper housing wall. The upper housing wall can be provided with foam strips and the compartment floor can be corrugated and provided with a fleece to better hold coins without rattling.
