<p>The present invention relates to a child-proof closure for a container containing a dangerous substance comprising a body adapted to be fitted over a container (8). The body (4) has a top portion and a continuous side wall extending downwardly from the top portion. The closure comprises a series of interlocking elements (1, 2, 3) located on the top portion and the side wall that are adapted to move in a predetermined sequence of steps to facilitate access to the substance. The interlocking elements are slides (1, 2, 3) adapted to slide within corresponding grooves (405) formed in the top portion and the side wall. The side wall has a cylindrical configuration. The closure (4) further comprises a membrane member (5) incorporated in a spaced relationship underneath the top portion. The membrane member comprises an opening (7) provided for limited distribution of the substance. The opening is accessible only after the interlocking (1, 2, 3) elements are placed into an operative or open position. The closure (4) comprises a horizontal slide (2) and two vertical slides (1 , 3) adapted to interlock opposite sides of the horizontal slide (4). The horizontal slide (2) is adapted to move left and right and the vertical slides (1, 3) are adapted to move down, and when in the closed position, the vertical slides (1, 3) are adapted to lock the movement of the horizontal slide (2).</p> |
