Abstract

A child-resistant lock means characterized in that a latch, switch, or like operating member therein adapted to be actuated by the tip of the forefinger is located at the end of an angular passage so that said operating member is inaccessible for operation by the forefinger of a child. The lock means herein is further characterized in that there is a lateral projection thereon adjacent the open end of the angular passage to prevent actuation of the operating member by a slender elongated object such as a stick or pencil.
