The invention relates to a case (10) for disk cartridges comprising a containing part (1) adapted to contain the disk cartridges (D), and a lid part (2) which is provided on an opening (1a) of the containing part (1) via a hinge part (3) and adapted to be freely opened and closed. There are provided at least one pair of locking portions (6a), (6b) which are adapted to be engaged with each other in areas near corners (c) of both side faces of the opening (1a) of the containing part (1) and an opening (2a) of the lid part (2). Therefore, the invention has made it possible to provide the case which can be simply manufactured and can obtain sufficient lock holding force required for practical use.
The invention features a child resistant, moveable closure member and container device and an overcap and container device. The overcap has opposed end walls and opposed sidewalls, with at least one leading locking pin and at least one trailing locking pin in at least one of said sidewalls. The inner closure may have at least one guiding bar, which extends downwardly from its lower surface, that is compatible in shape with an opening slot that may be in at least one of the sidewalls along the upper body of the container. The container further has a fixed cover portion facing the inner closure with a dispensing opening therethrough. At least one of the container sidewalls may have a closing notch, a stopping notch distal to the closing notch, and an opening notch therebetween. When the moveable closure is in the operative closure position, at least one of the leading locking pins is removably engaged in one of the closing notches and at least one of the trailing locking pins is removably engaged in at least one of the open notches, and the at least one guiding bar lies in the opening slot of the container. As the moveable closure is moved to its operative open position, the guiding bar engages and slidably travels along the opening slot. When the moveable closure is in its operative open position, at least one of the leading locking pins is removably engaged in one of the open notches and at least one of the trailing locking pins is removably engaged in one of the stopping notches.
