<p>A closure device for a container of the kind which is childproof by having an inner threaded cap (10) and an outer cap (16) which operates by turning the outer cap (16) in a closing direction while the inner (10) and outer (16) caps are operably engaged and which is free to rotate in the opposite direction without engagement of the inner cap (10); the improvement being that the outer cap (16) has an aperture (22) and the inner cap (10) has a slot (26) or other feature which can be engaged from outside by a coin or spoon handle. This makes the device easier for the old and infirm to open. <IMAGE></p> |
