Abstract: A child-proof container consisting of a casing (2) and a box (3) displaceably arranged therein, whereby the side walls (2a) of the casing at the interior are provided with locking members (4, 5) located diagonally to each other and intended to cooperate with recesses (6) in the side walls of the box, whereby the locking members are arranged to be able to be moved away from locking position in the recesses by means of external forces (A, B), which can be applied with two fingers diagonally on the casing to give this a rhomboidic shape, whereby at the same time a pressure force (C) exerted by a third finger can push the box out of the container.
