Closure systems for housing pharmaceuticals

A closure system comprising:

• an inner cap including a top surface, a circumferential side wall disposed below the top surface, and a plurality of driving structures disposed proximate a periphery of the top surface of the inner cap, each of the plurality of driving structures including a recess formed into the top surface, and each of the recesses having a bottom wall disposed at least partially on top of the side wall or formed into the side wall;
• a child proof element separated from the inner cap and being configured to be assembled with the inner cap to form a child proof cap having a child proof mode;
• and
• a key having a plurality of projections,
• wherein the child proof element when assembled with the inner cap in the child proof mode is configured to require the plurality of projections of the key to engage at least a portion of the plurality of driving structures of the inner cap to remove the assembled child proof cap when the child proof cap is installed on the container.

A closure system comprising:

• an outer cap including a plurality of driving structures;
• an inner cap dimensioned and configured to be assembled within the outer cap to form an assembled child resistant cap having at least a child resistant mode, the inner cap including:
• a closure engaging mechanism disposed on an interior surface of the inner cap, the closure engaging mechanism dimensioned and configured to engage a corresponding container engaging mechanism for securing the inner cap to a container,
• a plurality of driving structures, at least some of the plurality of driving structures of the inner cap being operable to engage the plurality of driving structures of the outer cap in the child resistant mode when the outer cap is turned in a first direction to screw the assembled closure onto a container and to permit removal of the assembled child resistant cap upon a push-down-and-turn action being applied to the outer cap in a second direction, and
• at least one key receiver disposed proximate an exterior surface of the inner cap;
• and
• a key having at least one projection extending from a handle portion, the at least one projection dimensioned and configured to engage the at least one key receiver of the inner cap for removing the assembled child resistant cap from the container when the key is rotated in the second direction.

A closure system comprising:

• a closure having a top surface, at least one side wall extending from an outer periphery of the top surface, a closure engaging mechanism dimensioned and configured to engage a corresponding container engaging mechanism for securing the closure to a container, and at least one key receiver;
• and
• a key for opening the closure system, the key comprising:
• a base surface and at least one side wall extending from at least a portion of the base surface in a first direction, and
• at least one projection extending from the base surface in the first direction, the at least one projection dimensioned and configured to engage the at least one key receiver of the closure system to rotate the closure for disengaging the closure engaging mechanism from the container engaging mechanism,
• wherein the base surface and the at least one side wall of the key is dimensioned and configured to correspond to the closure such that the base surface of the key covers at least a portion of the top surface of the closure and at least a portion of the side wall of the key abuts the side wall of the closure when the at least one projection of the key is engaged with the at least one key receiver of the closure.
