A captive key release closure structure includes a base ring for connection to a rim of a container, a closure member or cap integrally hinged to the base ring, latch indentations on an outer surface of a neck wall of the base ring, and latch pawls on an inner surface of a depending circumferential wall of the cap and aligned with the indentations. A key slot is formed in the cap wall at a position opposite the hinge, and a key receiving recess is formed in the base ring. The latch indentations and pawls are positioned in sets on opposite sides of the key slot and key recess. The closure structure is opened by insertion of a small keylike tool, such as a coin, spoon, or the like, and twisting against the surfaces forming the key slot and recess to separate and thereby release the pawls from the indentations. |
