Abstract

A container device by which a patron of a hotel or motel can leave articles such as shoes outwardly of the patron's room door for pick up and servicing by an attendant, but with the assuredness that the articles are locked for withdrawal only by an attendant who has lock-operation ability. No such ability is required of the patron, who achieves the locked condition of a container by the embrace of the patron's door by an abutment carried by a retainer connected to the container; and it is provided that the room door, in closed condition, itself is used both to block the container's access opening as well as to provide an abutment co-operating with the abutment to block movement of the device away from the door. The abutment is made movable, providing if desired another setting in which a full release of the container is achieved by pulling the abutment and its retainer outwardly of the door.
