<p>A one-piece cap closure (110) has a base (110) and a cap (120) joined to the base is a movable between an opened and a closed position. The base is provided with a key (170) and the cap is provided with a key-way (190) through which the key extends in an offset position relative to the key-way while the cap is in the closed position. The cap automatically locks the base via the offset orientation of the key with the key-way when the cap is pushed downward onto the base, such closing operation only requiring one finger. To open the closure, the key is turned so that it can pass through the key-way and the cap is lifted from the base, such turning and lifting action requiring both hands to work simultaneously.</p> |
