A receptacle comprises a hollow base, a hinged hollow lid and a catch 7 to hold the lid shut, the release mechanism for the catch comprising a plurality of tubular openings 5 leading into the interior of the receptacle and a trigger mechanism 6 which will release the catch, the trigger mechanism being randomly movable so that it can lie directly under each tubular opening, the arrangement being such that a ball when introduced through a tubular opening will either strike the trigger, thus allowing the receptacle to open, or pass into the interior of the receptacle. |
