Child-proof container

In a child-proof container of the type comprising a drawer which is slidably displaceable in a casing having at least one of its flat side walls made from a material which is flexible in the latitudinal direction and on the inside of said one flat side wall is provided with catch means extending therefrom towards the interior of the casing, the improvement wherein the casing comprises a tubular member which has a rectangular cross-section and is open a both ends, the catch means comprises at least two, spaced apart cam members located one near each one of the open ends of the casing and extending towards the interior thereof a distance exceeding the normal play between the casing and drawer, said cam members each having a substantially flat outer face inclined from said one flat side wall of said casing toward the adjacent open end and a substantially flat end face extending from and substantially perpendicular to said one flat side wall a distance sufficient to extend inside the edge of the adjacent end wall of the drawer when in the closed position thereby preventing unintentional opening of the container, and to release said edge to allow the drawer to be slidingly displaced to the open position by outward bending of said one flat side wall of the casing caused by forces acting toward said casing and substantially perpendicularly to the displacement direction of the drawer, the flat outer inclined face of the other cam member engaging said released edge to resist complete removal of said drawer from said casting.
